Definitions
- the present invention relates to the fields of thermodynamics and mechanics, and more specifically concerns a thermal regulation device for an electrical energy storage system.
- Such electrical energy storage systems are used in particular in electric or hybrid vehicles which are equipped, in addition to their service batteries intended to supply their on-board networks, with high-voltage batteries, of the order of 200 to 800 volts, intended in particular to supply their electric traction motors and other high-voltage devices.
- These high-voltage electrical energy storage systems are generally composed of electrical energy storage units, also called electrical energy storage cells, electrically grouped in battery packs, for example arranged under the floors of these vehicles.
- thermal regulation devices are necessary to cool the energy storage components that compose them, since an excessive increase in their temperature can damage them to the point of causing their destruction. These thermal regulation devices can also be useful for warming the energy storage components when their temperature is too low, for example when starting vehicles in very cold weather, since at low temperatures their performance is generally too low to allow these vehicles to operate optimally.
- thermal regulation devices each having a tube arranged between two rows of cells and within which heat transfer fluid is able to circulate.
- the tube has corrugations allowing a maximum contact surface with each cell to which it is adjacent. The contact between the tube and the cells allows an evacuation, or an input, of calories via the heat transfer fluid.
- a fluid distribution box is arranged at one end of the tube and heat transfer fluid inlet and outlet pipes are connected to this distribution box.
- the heat transfer fluid arriving via the inlet pipe flows at least partly into the tube via an inlet chamber provided in the distribution box, while the fluid leaving the tube, after having recovered calories for example to lower the temperature of the battery pack, flows into the outlet pipe via a return chamber also provided in the distribution box.
- the latter In order to allow the circulation of the heat transfer fluid within the tube, the latter is pierced with a multitude of circulation channels along which the heat transfer fluid circulates from one longitudinal end of the tube to the other. These channels are grouped into two circulation assemblies in order to allow circulation of heat transfer fluid in a first direction, away from the distribution box, distinct from circulation of heat transfer fluid in a second opposite direction.
- the inlet chamber within the distribution box fluidically communicate with the first circulation assembly within the tube and to make the return chamber fluidically communicate within the distribution box with the second circulation assembly within the tube, ensuring that there is no direct communication from the inlet chamber to the return chamber, to prevent, for example, heat transfer fluid heated during its passage through the tube from passing from the second circulation assembly to the inlet chamber and being reinjected hot into the tube.
- the inventors have designed such a regulation device, described in a patent application FR3125636, shown in part in figures 1 and 2, and which comprises a tube 6, a distribution box formed of two shells assembled one on the other in particular by means of attachment tabs 40, only one of the shells 11 being shown in FIG. i, in order to visualize the interior of the tube 6 and the arrival and return chambers of the distribution box.
- a regulation device described in a patent application FR3125636, shown in part in figures 1 and 2, and which comprises a tube 6, a distribution box formed of two shells assembled one on the other in particular by means of attachment tabs 40, only one of the shells 11 being shown in FIG. i, in order to visualize the interior of the tube 6 and the arrival and return chambers of the distribution box.
- the cold heat transfer fluid arrives via an inlet pipe 18b through an inlet orifice 46 in the arrival chamber, delimited by two hollows 42 of the shells 11 assembled one on top of the other, it enters channels 8 of a first heat transfer fluid circulation
- a return box connected to the other end of the tube 6 brings the heated heat transfer fluid into channels 8 of a second circulation assembly 23, adjacent to the first circulation assembly 21 in the tube 6, to the end face 12 of the tube 6.
- the heated heat transfer fluid enters the return chamber, delimited by two hollows 41 of the shells 11 assembled one on top of the other, then leaves through an outlet orifice 43 in an outlet pipe 18a connected to the return chamber.
- these chambers are separated by a central wall 44 formed by a rib on each of the shells 11. These ribs are brought into contact with a sealing zone 48 provided on the end face 12 between the first circulation assembly 21 and the second circulation assembly 23.
- this sealing zone 48 is a strip of material occupying the entire thickness and width of the tube between the first circulation assembly 21 and the second circulation assembly 23. Since the tube 6 is formed by extrusion, in this thermal regulation device, this strip of material extends longitudinally over the entire length of the tube 6, and is therefore expensive in material compared to its function. In addition, although the sealing zone 48 is thicker than a wall 50 delimiting two channels 8 of the same circulation assembly, it thermally transfers a lot of calories from the second circulation assembly 23 to the first circulation assembly 21, which is not desired. Finally, depending on the tube-distribution box assembly method chosen, it is not always possible to bring the ribs of the shells into contact with the sealing zone 48.
- the end of the tube 6 is inserted into a complementary receiving portion of the distribution box, thus ensuring the seal between the tube 6 and the distribution box, this insertion being carried out until contact between the ribs and the sealing zone 48, before brazing the tube 6 to the distribution box.
- first assembly method it is appropriate in this first assembly method to consider the dimension chain between a first corrugation of the tube 6, that is to say the corrugation or corrugation closest to the distribution box, and the center of a tube 18a, 18b for example, in order to be able on the one hand to ensure that the tube is well pressed against the cells and on the other hand to ensure that the distribution box of this tube can be connected via the tubes to a neighboring distribution box for the correct circulation of heat transfer fluid from one tube to the other.
- the manufacturing tolerance of the tube added to that of the distribution box implies a significant tolerance between the first corrugation of the tube 6 and the elements fixed on the distribution box such as the pipes 18a and 18b.
- a second assembly method the end of the tube 6 is inserted into a complementary receiving portion of the distribution box, thereby ensuring sealing between the tube 6 and the distribution box, until a longitudinal end of the shells 11 reaches a stop external to the regulating device, this external stop ensuring that the longitudinal end of the shells 11 is at a predetermined distance from the first corrugation of the tube 6.
- This second assembly method allows better control of the distance between the pipes 18a, 18b of the distribution box. distribution and the first corrugation, avoiding a link in the dimension chain and therefore reducing the necessary tolerance between the center of a tube 18a, 18b and the first corrugation, which does not depend on a manufacturing tolerance between the first corrugation and the end face 12 of the tube 6, unlike the first assembly method.
- this second assembly method does not guarantee that the ribs 44 of the distribution box are in contact with the sealing zone 48 and therefore a slight internal leak between the channels 8 of the first circulation assembly 21 and the channels 8 of the second circulation assembly 23 is possibly created.
- the inventors have therefore designed another tube 6b of another regulating device shown in FIG. 3, and also described in patent application FR3125636.
- This tube 6b comprises elements common to the tube 6, referenced in the same way, in particular a first circulation assembly 21 and a second circulation assembly 23 connected by a material bridge forming a sealing zone 48b on an end face 12b of the tube 6b.
- the distribution box of this other regulating device is identical to that described previously in relation to the tube 6.
- the material bridge connecting the two circulation assemblies 21, 23 is thinner than the central material strip of the tube 6.
- the tube 6b has much lower thermal conduction between the first circulation assembly 21 and the second circulation assembly 23.
- a cutting operation transverse of the tube 6b previously emerging in the form of a profile from an extrusion die generates a longitudinal burr at the sealing zone 48b.
- the cutting operation consists of a first pre-cutting step during which blades ci, C2 cut the profile on either side in a transverse direction T, that is to say along the width of the tube 6b, then in a second drawing step during which the tube 6b is separated longitudinally from the profile.
- this second drawing step which causes the longitudinal burr at the sealing zone 48b, because this zone, centered in the thickness of the tube 6b, has not undergone the pre-cutting step.
- this longitudinal burr prevents, during the assembly process mentioned above, any contact between the ribs 44 of the shells 11 of the distribution box, and the sealing zone 48b at the end face 12b.
- the tube 6b therefore allows better thermal insulation between the first circulation assembly 21 and the second circulation assembly 23, but requires an additional cutting operation to remove the longitudinal burr before assembling the tube 6b with the distribution box to allow contact between the ribs 44 and the sealing zone 48b at the end face 12b.
- thermo regulation device for an energy storage system, comprising a first heat transfer fluid circulation assembly and a second heat transfer fluid circulation assembly combined in the same tube while limiting the thermal conductivity and the fluid communication between these two circulation assemblies, and having a simple assembly, capable of allowing good alignment with another similar thermal regulation device without requiring restrictive manufacturing tolerances.
- the present invention aims to remedy at least in part the drawbacks of the prior art, by providing a thermal regulation device for an energy storage system, an energy storage system comprising such a device, a method of assembling such a device and a method of manufacturing a tube of such a device, in which the tube of the device comprises two heat transfer fluid circulation assemblies sufficiently insulated from each other thermally and fluidically, while reducing the manufacturing tolerances required in particular with respect to the tube of the thermal regulation device according to the invention.
- the invention proposes a thermal regulation device for cooling and/or heating components whose operation is sensitive to temperature, these components being in particular intended for energy storage and possibly being battery cells of electrical energy storage devices, comprising:
- a distribution box configured to be connected to a fluid inlet pipe and to a fluid outlet pipe, the distribution box comprising a fluid inlet chamber capable of being served by the inlet pipe and a fluid return chamber capable of serving the outlet pipe,
- each assembly comprising a plurality of circulation channels along which the heat transfer fluid circulates from one longitudinal end of the tube to the other, a first fluid circulation assembly communicating with the arrival chamber and a second fluid circulation assembly communicating with the return chamber, the fluid circulation assemblies having, in cross-section of the tube, long edges inscribed on two parallel straight lines, the material bridge breaking the continuity of material on at least one of the parallel straight lines by forming at least one longitudinal clearance of material on the tube, the thermal regulation device being characterized in that the distribution box comprises at least one rib separating the arrival chamber from the return chamber, a portion of the rib being housed in the clearance of material at a junction zone of the tube with the distribution box. distribution and in that the material bridge comprises a notch opening on an end face of the tube, the distribution box comprising a longitudinal excess thickness forming a projection from the rib and housed at least partly in the notch.
- the term “longitudinal” relates to a longitudinal direction which is understood as the direction along the main extension dimension of the tube, i.e. in the direction of its length.
- a transverse direction is understood as a direction orthogonal to the longitudinal direction, oriented in the direction of the width of the tube, i.e. parallel to the long edges of the cross-section of the tube which is made in a plane orthogonal to the longitudinal direction.
- Each of these long edges is inscribed on a straight line parallel to a straight line on which the other long edge is inscribed.
- the term “parallel” is of course understood as “substantially parallel” due to manufacturing tolerances, i.e. to within +/- 5 degrees.
- the tube of the thermal regulation device according to the invention therefore has a transversely oblong section allowing a cutting operation as described in the prior art.
- the circulation assemblies of the tube each have an alignment of channels between their long edges, the thickness of the tube at each circulation assembly, therefore orthogonal to the longitudinal and transverse directions, accommodating only one channel.
- the tube therefore has a thin section extending over the width of the tube, allowing good thermal conduction with cells of a storage system in which the thermal regulation device is used.
- the tube may include corrugations (or undulations) allowing good contact with these cells when they are cylindrical.
- the width of the tube is generally imposed by the size of the cells to be cooled, for example the height of their cylindrical shape if the thermal regulation device is housed between two rows of cells. If each row of cells comprises n superimposed cylindrical cells, the height to be considered can of course be multiplied by the same factor n.
- Each tube width thus defined for a storage system imposes a dimensioning and a number of channels in the fluid circulation assemblies, this number being able to be identical or different in each of these fluid circulation assemblies.
- this dimensioning takes into account the mechanical strength of the tube, faced with a maximum pressure of the fluid circulating in the channels, of several bars, and takes into account the thermal performance of the tube, in order to effectively cool or heat the cells, and this with very good thermal homogeneity between the different channels of the same fluid circulation assembly.
- the tube of the thermal regulation device according to the invention is preferably formed by extrusion and its cross section is therefore preferably identical over the entire length of the tube, except at its end comprising the notch, produced for example during a step of cutting an extruded profile of the tube.
- the tube is machined, and the material bridge is not present over the entire longitudinal length of the tube, but over certain portions of this length and in particular at the end of the tube.
- the material bridge is thinner than the strip of material of the prior art shown in FIG. 2.
- the material bridge is in one piece and has only two ends transversely to the tube, for example being of a cross section similar to that of FIG. 3.
- the assembly of the thermal regulation device according to the invention does not require great precision in the dimensioning of the end of the tube relative to a first corrugation of the tube or more generally to a first contact surface provided with an element to be cooled, the first corrugation or contact surface being that closest to the distribution box.
- the production of the notch at the end of the material bridge makes it possible to eliminate the longitudinal burr created when cutting the tube, which allows better control of the relative positions of the distribution box and the tube.
- the longitudinal excess thickness inserted in the notch makes it possible to greatly limit the circulation of fluid between the first circulation assembly and the second circulation assembly regardless of the longitudinal position of the longitudinal excess thickness in the notch, since this circulation will be controlled by the transverse position of the longitudinal excess thickness relative to the side walls of the circulation assemblies which frame it.
- the seal between the circulation assemblies of the tube is complete. It should be noted that the longitudinal excess thickness extending orthogonally to the transverse and longitudinal directions can therefore merge with the rib if the latter stops longitudinally at the level of a bottom wall of the notch.
- the clearance of material forming on the tube a groove extending longitudinally on the tube, the rib fills the groove on a longitudinal portion of the bridge of material, and the longitudinal excess thickness forms a longitudinal stop capable of coming against the bottom wall of the notch, the excess thickness starting on the rib in the notch and ending at a longitudinal end of the distribution box on the side opposite the tube.
- a distance between a lateral edge of the longitudinal excess thickness and a lateral edge of the notch is between 0.02 and 0.2 times a width of the notch.
- This distance is the most controllable in terms of dimension chain and guarantees low fluid circulation between the circulation assemblies even when the longitudinal excess thickness is quite far from a bottom wall of the notch, orthogonal to the lateral edges of the notch.
- the width of the notch is of course the transverse distance between the lateral edges of the notch. This dimensioning makes it possible to limit an internal leak between the first circulation assembly and the second circulation assembly, so as to maintain an acceptable thermal efficiency of the thermal regulation device according to the invention.
- the distance between an end edge of the longitudinal excess thickness and the bottom wall of the notch is non-zero but smaller than the distance between the end face of the tube and the end edge of the longitudinal excess thickness, these distances being measured longitudinally and therefore in the direction of the length of the tube. This further limits the passage of fluid from one circulation assembly to the other, in particular when the contours of the longitudinal excess thickness are rounded, which is the case when the distribution box is formed partly by stamping.
- the distance between the end face of the tube and the end edge of the longitudinal excess thickness, when the tube is inserted into the distribution box, is greater than or equal to a radius of curvature characterizing a rounded edge between a lateral edge of the longitudinal excess thickness and the end edge of the longitudinal excess thickness.
- the longitudinal excess thickness is in contact with the material bridge on the bottom wall of the notch, preventing any circulation of fluid between the circulation assemblies or limiting it to the maximum when the end edge of the longitudinal excess thickness is rounded.
- the longitudinal excess thickness in fact makes it possible to cover the entire thickness of the tube, possibly in cooperation with another longitudinal excess thickness or another rib as explained below.
- the distribution box comprises a receiving portion of a shape complementary to a longitudinal end portion of the tube in the junction zone, the longitudinal end of the tube being fitted into the receiving portion.
- This complementary shape produced in particular by means of the ribs mentioned above, makes it possible to ensure sealing between the distribution box and the tube.
- the tube is for example brazed with the distribution box once the tube is inserted into it.
- the recesses forming the chambers on the one hand, and the ribs on the other hand, are easily formed by stamping metal plates forming each one of the two shells, which are then brazed or welded to each other to form the distribution box.
- the excess thickness(es) of the ribs are preferably formed by stamping and therefore do not necessarily correspond to an excess of material on the ribs, but to an extension of the latter in the direction of the thickness of the distribution box.
- the shells are preferably one-piece.
- the ribs are alternatively formed by a deformation of the sheet metal, or by an excess of material.
- the ribs contribute to the sealing between the distribution chambers by longitudinally separating the two recesses on each of the shells.
- the ribs with the longitudinal excess thickness(es) form a central wall separating the two chambers on a longitudinal portion of the distribution box over the entire thickness thereof, and fill the material clearances formed by the material bridge on another longitudinal portion of the distribution box covering the junction zone, so as to ensure sealing between the tube and the distribution box.
- the ribs extend longitudinally in fact from an edge of each shell corresponding to a longitudinal end of the receiving portion, in contact with the material bridge, to an unstamped area of the shell extending to the opposite edge of the shell.
- the non-stamped areas of the shells are pressed together when the shells are assembled and then brazed, thus extending the seal between the two chambers longitudinally to the opposite edge of each shell.
- the ribs therefore extend longitudinally beyond the walls of the material bridge from the tube to the distribution box.
- the material bridge connects the two circulation assemblies by forming two material clearances on the tube, each corresponding to a longitudinal groove on the tube.
- the tube is preferably made of metal material, such as aluminum, and formed by extrusion then cutting.
- the distribution box is formed by two shells fixed to one another, each shell comprising a first recess forming one half of the inlet chamber and a second recess forming one half of the return chamber.
- the distribution box is preferably also made of metal material, for example aluminum.
- the distribution box unlike the tube, is preferably made by stamping. Alternatively, the distribution box is machined. Materials other than aluminum are of course conceivable for the tube and the distribution box, provided that they are thermally conductive and have sufficient mechanical strength to not deform under the pressure of the heat transfer fluid.
- the distribution box comprises a rib on each shell, the rib separating the arrival chamber from the return chamber and filling at least on the junction zone, one of the longitudinal grooves, the rib being surmounted by a longitudinal excess thickness housed at least partly in the notch, the longitudinal excess thicknesses being in contact with each other.
- the distribution box comprises a rib on each shell, the rib separating the arrival chamber from the return chamber and filling at least on the junction zone, one of the longitudinal grooves, the rib of one of the shells being surmounted by a longitudinal excess thickness housed at least partly in the notch, said longitudinal excess thickness being in contact with the rib of the other of the shells.

- FIG. 12 represents steps of a method of assembling a thermal regulation device according to the invention in one embodiment of the invention.
- FIG. 4 illustrates an embodiment of a thermal regulation device 4 according to the invention, comprising an aluminum tube 60, one longitudinal end of which is fitted into a distribution box 100 and the other longitudinal end of which is fitted into a return box 20.
- the circulation of the fluid is said to be U-shaped, that is to say with the same portion of heat transfer fluid which circulates in two opposite directions Si, S2 of circulation within the tube 60.
- the thermal regulation device 4 comprises corrugations to optimize its exchange surface with cylindrical battery cells.
- a first corrugation 63 of the tube is positioned so that the pipes of the distribution box 100 are coaxial with other pipes of another distribution box 100 as explained below.
- the heat transfer fluid arrives in the thermal regulation device 4 via an inlet pipe 18b connected in a sealed manner to an inlet chamber 410 (referenced FIG. 8) of the distribution box 100, enters a first circulation assembly 61 of the tube 60, circulates in the first direction Si to the return box 20 which diverts it to a second circulation assembly 62 of the tube 60.
- the heat transfer fluid circulates in the second direction S2 to a return chamber 420 (referenced FIG. 8) of the distribution box 100, then leaves via an outlet pipe 18a connected in a sealed manner to the return chamber 420.
- the thermal regulation device 4 is in fact used to cool an electrical energy storage system 1 shown in FIG. 5, intended in particular to equip an electric or hybrid vehicle.
- This electrical energy storage system 1 comprises several electrical energy storage members 2, here cylindrical cells 2, accumulators of energy and electrically connected to each other in series.
- the cylindrical cells 2 are arranged vertically, that is to say perpendicular to the plane in which the electrical energy storage system is mainly located.
- the electrical energy storage system 1 comprises several thermal regulation devices 4 each comprising a tube 60, arranged between two rows 3 of cylindrical cells 2, or flanking such a row 3 at the edge of the energy storage system 1, so as to allow a thermal exchange between the thermal regulation devices 4 and the cylindrical cells 2.
- the tubes 60 are corrugated in order to allow an optimal exchange surface with the cylindrical cells 2. They are made for example of aluminum.
- the arrangement of the thermal regulation devices 4 is such that the return boxes 20 of the thermal regulation devices 4 are on the same side of the energy storage system 1, outside the rows 3 of cylindrical cells 2. Similarly, the distribution boxes 100 of the thermal regulation devices 4 are all on the opposite side of the energy storage system 1, outside the rows 3 of cylindrical cells 2.
- a connection system 18, detailed below makes it possible to connect all the distribution boxes 100 together, so that they can receive a heat transfer fluid from the same heat transfer fluid inlet 14 for the entire energy storage system 1, and so that this heat transfer fluid can be evacuated by the same heat transfer fluid evacuation 16 for the entire energy storage system 1.
- connection system 18 provides for each thermal regulation device 4 between two rows 3 of cylindrical cells 2: - an inlet pipe 18b serving the arrival chamber 410 of the distribution box 100 of the thermal regulation device 4,
- an evacuation pipe 18e capable of receiving an outlet pipe 18a from a distribution box 100 of a thermal regulation device 4 adjacent to the thermal regulation device 4 comprising this evacuation pipe 18e.
- Each service pipe 18c includes in particular a toroidal seal 36 for ensuring the sealing of its fitting into an inlet pipe 18b, and each outlet pipe 18a includes a toroidal seal for ensuring the sealing of its fitting into an evacuation pipe 18e.
- the seals 36 are held radially tight by the fitting of the corresponding pipes, which are held one inside the other by the presence of a ring 52 preventing their relative axial displacement.
- the tube 60 of this embodiment of the invention is shown in FIG. 7, seen in cross-section, that is to say in a plane orthogonal to a longitudinal direction oriented along the length of the tube 60, at the level of a solid part of a material bridge 64 connecting the first fluid circulation assembly 6i of the tube 60, and the second fluid circulation assembly 62 of the tube 60.
- This cross-section shows the tube 60 on the one hand according to its width, corresponding to the largest dimension of the tube 60 on this cross-section, and in the direction of alignment of the channels 8 relative to each other in each fluid circulation assembly 61, 62, and on the other hand according to its thickness, in a direction orthogonal to that of the width of the tube.
- the width of the tube 60 is oriented in a transverse direction T and the thickness of the tube 60 in a direction E.
- the channels 8 are each separated by a wall 50 in the width direction of the tube 60. It can be seen that the tube 60 is very thin, of the order of a few millimeters, a single channel 8 being able to be housed in the thickness direction of the tube 60, which allows the tube 60 to be cut at the outlet of an extrusion die by a first pre-cutting step then a second drawing step.
- the first fluid circulation assembly 61 therefore has, in the width of the tube 60 on this cross section, a first long edge 612 which is inscribed on a first straight line di, and a second opposite long edge 611 which is inscribed on a second straight line d2 substantially parallel to the first straight line di.
- the second fluid circulation assembly 62 has in the width of the tube 60 on this cross section, a first long edge 622 which is inscribed on the first straight line di, and a second long edge 621 which is inscribed on the second straight line d2.
- the material bridge 64 breaks the continuity of material on the parallel lines di, d2 by forming a first clearance of material 66 between the two edges 612, 622 on a first longitudinal face of the tube 60, and a second clearance of material 65 between the two edges 611, 621 on a second longitudinal face of the tube 60 opposite the first longitudinal face of the tube 60.
- the tube 60 being formed by extrusion, in this embodiment of the invention, these material clearances 65, 66 extend over the entire length of the tube, forming longitudinal grooves opening towards the outside of the tube 60, between the circulation assemblies 61, 62.
- the tube 60 comprises a notch 642, visible in FIG. 8, formed in these longitudinal grooves and opening onto an end face 602 (referenced FIG. 9) of the tube 60.
- the end face 602 is a flat surface comprising the opening of the channels 8 of the circulation assemblies 61, 62. It is parallel, at the level of the notch 642, to a bottom wall 644 of the notch 642.
- the notch 642 cooperates with sealing means 440 of the distribution box 100 when the tube 60 is inserted into the distribution box 100, now described in relation to FIG. 8.
- a longitudinal direction L to which the term “longitudinal” refers is oriented along the length of the tube 60, orthogonal to the transverse direction T oriented along the width of the tube 60 and to the direction E oriented along the thickness of the tube 60.
- These directions are also used to position the distribution box 100 in Figures 8 to 10.
- the largest dimension of the distribution box 100 is oriented along the transverse direction T, this largest dimension being oriented along the width of the tube 60 when the latter is fitted into the distribution box 100.
- an intermediate dimension of the distribution box 100, oriented in the direction of insertion of the tube 60, is oriented along the longitudinal direction L, and the smallest dimension or thickness of the distribution box 100 is oriented along the direction E.
- the distribution box 100 is formed of two shells 111 assembled against each other and then brazed. Lateral hooking tabs on one of the shells allow the shells 111 to be held against each other during brazing.
- the distribution box 100 is made of aluminum, in this embodiment of the invention. Alternatively, it can of course be made of another material, metal or polymer for example.
- Each shell 111 comprises a first recess forming one half of the arrival chamber 410 and a second recess forming one half of the return chamber 420. These recesses are for example formed by stamping. Each first recess is pierced with an orifice bordered by a cylindrical base 181 intended to receive either an inlet pipe 18b or a service pipe 18c.
- each second recess is pierced with an orifice bordered by a cylindrical base 183 intended to receive either an outlet pipe 18a or an evacuation pipe 18e.
- the distribution box 100 extends longitudinally from a junction edge 1112 of each shell 111 with the tube 60, therefore proximal to the tube 60, to a free edge 1114 of each shell, opposite the junction edge 1112, therefore distal to the tube 60.
- the distribution box 100 comprises a receiving portion of a shape complementary to at least one longitudinal portion of a junction zone 600 on the end of the tube 60, this junction zone being fitted into this receiving portion, when the tube 60 is inserted into the distribution box 100.
- the receiving portion is complementary to the junction zone 600 at least on the longitudinal portion of this junction zone 600 extending longitudinally from the junction edge 1112 of each shell 111 to the bottom wall 644 of the notch.
- Each shell 111 further comprises a rib 441 separating the two chambers and matching the shape of one of the material clearances 65, 66 longitudinally over the entire junction zone 600.
- each rib 441 of a shell 111 fills an end portion of a longitudinal groove formed by a material clearance 65, 66, such that the shells 111 grip the material bridge 64 in a pincer movement at the junction zone 600. Due to the contact planes between each rib 441 and the material bridge 64, parallel to the transverse T and longitudinal L directions, the ribs 441 do not fill the notch 642 on the junction zone. 6oo, in this embodiment of the invention. According to the invention, and as will be detailed below, the notch 642 is partially occupied by a longitudinal excess thickness 442 forming on each rib 441 a projection in the direction E.
- each longitudinal excess thickness 442 begins on the corresponding rib 441, with an end edge 4422 located at a distance from the junction edge 1112 of the shell 111, from where the rib 441 begins, and extends longitudinally to the non-stamped zone of the shell 111 located between the two chambers 410, 420.
- the longitudinal distance between the start of the rib 441 and the start of the longitudinal excess thickness 442 makes it possible, thanks to the complementary shapes of the ribs 441 and the material bridge 64 over this distance, to ensure sealing between the tube 60 and the distribution box 100.
- the longitudinal excess thicknesses 442 and the ribs 441 also form the sealing means 440 between the two chambers.
- the ribs 44 formed for example by stamping, participate in separating the arrival chamber 410 from the return chamber 420, by forming a central wall between these two chambers, and therefore participate in the sealing between the arrival chamber 410 and the return chamber 420.
- the ribs 441 extend longitudinally between the two chambers from the joining edge 1112 of each shell 111, to an unstamped area of the shell 111 extending in the vicinity of the free edge 1114 of the shell 111.
- the unstamped areas of the shells 111 are pressed against each other during assembly of the shells 111 and then brazed, and thus extend the seal between the two chambers longitudinally to the free edge 1114 of each shell 111.
- the ribs 441 have a thickness extending on the shell 111 in the direction E up to the material bridge 64 only, when the tube 60 is inserted into the distribution box 100.
- the heat transfer fluid can therefore pass from the channels 8 of the second circulation assembly 62 on the end face 602 of the tube 60 to the bottom wall 644 of the notch 642, and circulate on this bottom wall 644 to the circulation channels 8 of the first circulation assembly 61 by going up on the end face 602 of the tube 60.
- the longitudinal excess thicknesses 442 extend into the notch, forming a projection on their respective rib 441 along the direction E, until they meet one another and obstruct, at least partially, the notch.
- this sealing cannot be complete if the end edge 4422 does not touch the bottom wall 644 of the notch, or if none of the lateral edges 4426, 4424 of the longitudinal excess thickness 442 touches one of the lateral edges 646, 648 of the notch 642, the lateral edges of the longitudinal excess thickness 442 and of the notch 642 extending in the longitudinal direction L.
- the end edge 4422 of the longitudinal excess thickness 442 touches the bottom wall 644 of the notch, or one of the lateral edges 4426, 4424 of the longitudinal excess thickness 442 touches one of the lateral edges 646, 648 of the notch 642, the corresponding edge(s) of the extra thickness 442 having a flat surface parallel to the bottom wall 644 or to one of the lateral edges 646, 648 of the notch 642.
- complete sealing is achieved between the circulation assemblies 61, 62.
- the excess thickness 442 being produced by stamping, its edges are rounded, and as a result the sealing between the circulation assemblies 61, 62 is not complete but is sufficient thanks in particular to the control of the relative distances between the lateral edges 4426, 4424 of the longitudinal excess thickness 442 and the lateral edges 614, 616, 624, 626 of the circulation assemblies 61, 62.
- the width of the notch is smaller than the transverse distance between the two circulation assemblies 61, 62.
- the longitudinal excess thickness 442 is itself, at least over a longitudinal end portion, of a width less than the width of the rib 441 whose thickness it extends, so as to be able to be housed in the notch 642.
- the manufacturing tolerances of the shells 111 and the tube 60 allow a distance d between one of the lateral edges 4426, 4424 of the longitudinal excess thickness 442 and one of the lateral edges 646, 648 of the notch 642 to be between 0.02 and 0.2 times the width of the notch 642.
- this distance d is approximately half a millimeter, and the width of the notch approximately 4 millimeters.
- the largest dimension of the internal leak section between the two chambers is therefore of the order of half a millimeter, or four times less than in the prior art.
- the notch 642 extends transversely from the lateral edges 614, 616 of the first circulation assembly 61 to the lateral edges 624, 626 of the second circulation assembly 62.
- the distance d between one of the lateral edges 4426, 4424 of the longitudinal excess thickness 442 and one of the lateral edges 614, 616, 624, 626 of the circulation assemblies 61, 62 is between 0.02 and 0.2 times a distance between the lateral edges 614, 616 of the first circulation assembly 61 and the lateral edges 624, 626 of the second circulation assembly 62.
- a distance h between the end edge 4422 of the longitudinal excess thickness 442 and the bottom wall 644 of the notch is smaller than the distance between the end face 602 of the tube 60 and the end edge 4422 of the excess thickness 442, these distances being measured in the longitudinal direction L.
- the distance h can be half a millimeter or several millimeters without the internal leakage being greater in both cases, provided that the distance d is controlled and remains identical, for example of about half a millimeter.
- the longitudinal depth of the notch 642 is of course always greater than the distance h.
- the distance between the end face 602 of the tube 60 and the end edge 4422 of the longitudinal excess thickness 442, when the tube 60 is inserted into the distribution box 100, is greater than or equal to a radius of curvature R characterizing a rounded edge between a lateral edge 4424, 4426 of the longitudinal excess thickness and the end edge 4422 of the longitudinal excess thickness 442.
- the manufacturing method 300 comprises:
- pre-cutting step 304 of a part of the profile of the tube 60 thus manufactured this pre-cutting being carried out transversely to the tube 60 along the parallel lines di, d2, at a location spaced longitudinally from one end of the profile of the tube 60, from the length of the tube 60, and
- the pre-cut and separated part forms a tube 60 of the thermal regulation device 4 without a notch.
- a last step is a cutting step 308 of the notch 642 on one end of the material bridge 64 of the tube 60 without a notch resulting from the separation step 306. It should be noted that in this embodiment, each pre-cutting and separation step forms one end of the remainder of the tube profile 60, not yet pre-cut, which will be used to manufacture another tube.
- the distribution box 100 is formed by superimposing the two shells 111 against each other.
- a longitudinal end of the tube 60 is inserted inside the distribution box 100 until the longitudinal excess thicknesses 442 on the ribs 441 of the shells 411 are housed at least partly in the notch 642 of the material bridge 64.
- a third step 206 the assembly formed by the distribution box 100 and the tube 60 thus inserted into the distribution box 100 is brazed.
- the tube 60 is inserted into the distribution box 100 until the end edge 4422 of the longitudinal excess thickness 442 reaches the bottom wall 644 of the notch. This limits as much as possible the circulation of fluid between the two chambers 410, 420 of the distribution box 100.
- the longitudinal end of the tube 60 is inserted inside the distribution box 100 by bringing the latter against a stop external to the thermal regulation device 4 and placed at a predetermined distance between the first corrugation 63 of the tube 60 and its longitudinal end.
- This variant generally does not ensure contact between the end edges 4422 of the longitudinal excess thicknesses 442 with the bottom wall 644 of the notch 642. Nevertheless, any internal leakage that may be created is controlled.
