Description
Titre : Module d'échange de chaleur pour deux circuits d'échange de chaleur Title: Heat Exchange Module for Two Heat Exchange Circuits
La présente invention concerne un échangeur de chaleur destiné à refroidir un fluide circulant dans un circuit grâce à un flux d'air.The present invention relates to a heat exchanger for cooling a fluid flowing in a circuit through a flow of air.
Elle a plus particulièrement comme objet, mais non exclusivement, un module d'échange de chaleur pour véhicules automobiles comportant deux circuits distincts d'échange de chaleur, dans lesquels circulent un même fluide caloporteur (fluide transportant de la chaleur), le fluide de ces deux circuits étant refroidi par un même flux d'air.It has more particularly as object, but not exclusively, a heat exchange module for motor vehicles comprising two separate heat exchange circuits, in which circulate the same heat transfer fluid (fluid carrying heat), the fluid of these two circuits being cooled by the same air flow.
On connaît à l'heure actuelle un multi- échangeur à fluide identique dans les deux circuits thermiques tel que présenté dans le document EP155886. Une telle réalisation est un module d'échange de chaleur destiné à être parcouru par au moins un fluide caloporteur d'une première et d'une deuxième boucle d'échange de chaleur, ledit fluide étant le même dans les deux boucles, ledit module comprenant au moins deux échangeurs de chaleur possédant chacun une boîte collectrice d'entrée, une boîte collectrice de sortie, un faisceau d'échange de chaleur dans lequel circule ledit fluide caloporteur en relation avec lesdites boîtes, lesdits faisceaux étant propres à être balayés successivement par un même flux d'air.At present, a multi-exchanger with identical fluid is known in the two thermal circuits as presented in document EP155886. Such an embodiment is a heat exchange module intended to be traversed by at least one heat transfer fluid of a first and a second heat exchange loop, said fluid being the same in both loops, said module comprising at least two heat exchangers each having an inlet manifold, an outlet manifold, a heat exchange bundle in which said heat transfer fluid circulates in relation to said boxes, said bundles being adapted to be successively scanned by a same airflow.
L'inconvénient principal de ce type d'échangeurs de chaleur réside dans le fait que leurs boîtes collectrices sont entièrement réalisées en aluminium, ce qui les rend coûteuse, en particulier à cause de leurs fabrications plus complexe. En effet, il est notamment nécessaire de rapporter des moyens de fixation ainsi que les tubulures nécessaires pour l'entrer et la sortie du ou des fluides.The main disadvantage of this type of heat exchanger lies in the fact that their collector boxes are made entirely of aluminum, which makes them expensive, in particular because of their more complex fabrications. Indeed, it is in particular necessary to report fastening means and the tubing necessary to enter and exit the fluid or fluids.
La présente invention entend remédier aux inconvénients des échangeurs de chaleur existants en proposant une réalisation particulière apte à autoriser l'utilisation d'une autre matière que l'aluminium, et plus précisément une matière non-métallique, à savoir le plastique.The present invention intends to overcome the drawbacks of existing heat exchangers by proposing a particular embodiment capable of authorizing the use of a material other than aluminum, and more specifically a non-metallic material, namely plastic.
Ainsi, l'invention concerne un module d'échange de chaleur destiné à être parcouru par au moins un fluide caloporteur d'une première et d'une deuxième boucle d'échange de chaleur, ledit fluide étant le même dans les deux boucles, ledit module comprenant au moins deux échangeurs de chaleur possédant chacun une boîte collectrice d'entrée, une boîte collectrice de sortie, un faisceau d'échange άo chaleur dans lequel circule ledit fluide caloporteur en relation avec lesdites boîtes, lesdits faisceaux étant propres à être balayés successivement par un même flux d'air, caractérisé en ce que les boîtes collectrices d'entrée et de sortie sont communes aux deux échangeurs de chaleur.Thus, the invention relates to a heat exchange module intended to be traversed by at least one heat transfer fluid of a first and a second heat exchange loop, said fluid being the same in both loops, said module comprising at least two heat exchangers heat each having an inlet manifold, an outlet manifold, a heat exchanger bundle in which circulates said heat transfer fluid in relation to said boxes, said bundles being adapted to be successively scanned by a same air flow , characterized in that the inlet and outlet manifolds are common to both heat exchangers.
On entend par l'expression « boîtes collectrices d'entrée et de sorties communes » le fait que ces boîtes collectrices sont constituées du ou de ces mêmes éléments, autrement dit le ou les éléments utilisé(s) constitue(nt) la structure, ou la constitution de ces boîtes collectrices.The expression "common inlet and outlet manifolds" means that these manifolds consist of the same element or elements, ie the element (s) used constitute (s) the structure, or the constitution of these collector boxes.
Grâce à l'invention et le fait que le module d'échange de chaleur soit apte à la circulation de deux fluides identiques, on peut prévoir sans mesure particulière que la plaque collectrice soit commune aux deux rangs de tubes de chacun des circuits thermique, respectivement basse et haute températures. En effet, les phénomènes de dilatation thermique dans un multi- échangeur, c'est-à-dire incluant au moins deux fluides circulant dans deux circuits distincts, sont très différents lorsque ces deux fluides sont différents et lorsque ces deux fluides sont identiques. Lorsque ces deux fluides sont identiques (c'est-à-dire mêmes caractéristiques thermiques : conduction, conversion et rayonnement de chaleur), même à des températures différentes, les dilatations thermiques sont bien moindres que lorsque ces deux fluides sont de nature différente et par ailleurs à des températures différentes. Ainsi, la plaque collectrice commune aux deux rangs de tubes de chacun des circuits thermiques de fluide n'est rendu possible que lorsque les fluides de deux circuits sont les mêmes.Thanks to the invention and the fact that the heat exchange module is suitable for the circulation of two identical fluids, it can be provided without any particular measure that the collector plate is common to the two rows of tubes of each of the thermal circuits, respectively low and high temperatures. Indeed, the phenomena of thermal expansion in a multi-exchanger, that is to say including at least two fluids flowing in two separate circuits, are very different when these two fluids are different and when these two fluids are identical. When these two fluids are identical (that is to say, the same thermal characteristics: conduction, conversion and heat radiation), even at different temperatures, the thermal expansions are much less than when these two fluids are of different nature and by elsewhere at different temperatures. Thus, the collector plate common to the two rows of tubes of each of the fluid thermal circuits is made possible only when the fluids of two circuits are the same.
Par ailleurs, la présente invention permet l'utilisation d'un couvercle en plastique, en particulier pour la partition longitudinale et/ou la ou les partition(s) transversales/axiales, ce qui réduit sensiblement les coûts de matière ainsi que les coûts de fabrication car le plastique est plus facile à travailler pour la conception d'une boîte de forme particulière. Relativement au procédé de fabrication, on notera que le procédé de réalisation d'une boîte collectrice selon l'invention n'est pas modifié ou complexifié par rapport à l'art antérieur.Furthermore, the present invention allows the use of a plastic cover, in particular for the longitudinal partition and / or the transverse / axial partition (s), which substantially reduces the material costs as well as the costs of manufacturing because plastic is easier to work for the design of a particular form box. With respect to the manufacturing process, it should be noted that the method of making a box collector according to the invention is not modified or complicated compared to the prior art.

Un mode de réalisation de l'invention sera décrit ci-après, à titre d'exemple non limitatif, en faisant référence aux dessins annexés dans lesquels : - La figure 1 représente un collecteur selon l'invention réceptionnant deux rangées de tubes ;An embodiment of the invention will be described hereinafter, by way of non-limiting example, with reference to the appended drawings in which: - Figure 1 shows a manifold according to the invention receiving two rows of tubes;
- La figure 2 est une vue schématique d'en haut considérant les deux rangées de tubes et leur séparation par la cloison longitudinale issue du couvercle du collecteur ;- Figure 2 is a schematic view from above considering the two rows of tubes and their separation by the longitudinal partition from the cover of the collector;
- La figure 3 illustre un autre collecteur selon l'invention vue d'en haut avec une cloison transversale ou axiale.- Figure 3 illustrates another collector according to the invention seen from above with a transverse or axial partition.
Le collecteur choisi pour illustrer l'invention comprend un couvercle 1 et une plaque collectrice 2. Ces deux éléments 1, 2 sont communs aux deux rangées de tubes 3, 4, donc aux deux circuits d'échange de chaleur et forment indifféremment le collecteur d'entrée ou de sortie pour l'un et/ou l'autre de ces deux circuits d'échange de chaleur.The collector chosen to illustrate the invention comprises a cover 1 and a collector plate 2. These two elements 1, 2 are common to the two rows of tubes 3, 4, therefore to the two heat exchange circuits and form indifferently the collector input or output for one and / or the other of these two heat exchange circuits.
Le couvercle 1 est en matière plastique, par exemple en polyamide, et présente une section de forme sensiblement semi-circulaire avec une branche linéaire 5 s'étendant de sa périphérie ou contour. Ce couvercle 1 comprend des extrémités de forme sensiblement parallélépipédique 6, légèrement décalées des extrémités issues de la section circulaire du couvercle. Ces extrémités parallélépipédiques 6 permettent ou sont adaptées pour le sertissage du couvercle 1 sur la plaque collectrice 2. En effet, la plaque collectrice 2 s'étend sensiblement de façon coplanaire, et classique, dans sa partie destinée à la réception des extrémités de tubes de chacune des rangées 3, 4 et comprend à ses extrémités respectivement une partie recourbée 7 destinée à accueillir ou loger les extrémités parallélépipédiques. Par ailleurs, les parties recourbées 7 de la plaque collectrice 2 se terminent par des dents 8, ou analogues, de sertissage destinées à être serties sur les extrémités parallélépipédiques 6 du couvercle 1 et fixer ses deux éléments 1 et 2 entre eux. Accessoirement, il sera prévu un élastomère ou joint d'étanchéité 9 destiné à améliorer le sertissage/fixation en évitant toute fuite de fluide. La plaque collectrice 2 comprend ici deux séries d'orifices pour la réception de chacun des faisceaux d'échange de chaleur 3, 4, en l'occurrence les extrémités de tubes. Ces deux rangées d'orifices sont alignées de sorte que les orifices, ou leurs rangées respectives, présentent le même pas.The lid 1 is made of plastic, for example polyamide, and has a section of substantially semicircular shape with a linear branch 5 extending from its periphery or contour. This lid 1 comprises ends of substantially parallelepipedal shape 6, slightly offset from the ends from the circular section of the lid. These parallelepipedal ends 6 allow or are adapted for crimping the cover 1 on the collector plate 2. In fact, the collector plate 2 extends substantially coplanar, and conventional, in its part intended for receiving the ends of the tubes of each of the rows 3, 4 and comprises at its ends respectively a curved portion 7 for receiving or housing the parallelepipedal ends. Furthermore, the bent portions 7 of the header plate 2 end with teeth 8 or similar, crimping intended to be crimped on the parallelepipedic ends 6 of the cover 1 and fix its two elements 1 and 2 between them. Incidentally, there will be provided an elastomer or seal 9 for improving the crimping / fixing avoiding any leakage of fluid. The collecting plate 2 here comprises two series of orifices for receiving each of the heat exchange beams 3, 4, in this case the ends of tubes. These two rows of orifices are aligned so that the orifices, or their respective rows, have the same pitch.
La cloison longitudinale 5 présente une section de matière décroissante en direction de la plaque collectrice 2. A la base de la cloison longitudinale 5, c'est-à-dire du côté de la plaque collectrice 2, on pourra prévoir de disposer également (à l'instar de la fixation des parties parallélépipédiques 6 avec la plaque collectrice 2) un joint d'étanchéité 9 dans une gorge 13, prévue entre les deux séries d'orifices de la plaque collectrice 2, destiné à éviter le mélange des fluides de chacune des boîtes collectrices 10, I LThe longitudinal partition 5 has a section of decreasing material in the direction of the header plate 2. At the base of the longitudinal partition 5, that is to say on the side of the collector plate 2, provision may also be made for as is the fixing of the parallelepipedal parts 6 with the header plate 2) a seal 9 in a groove 13, provided between the two series of orifices of the header plate 2, intended to prevent the mixing of the fluids of each manifolds 10, IL
On pourra envisager que le joint d'étanchéité 9 prévu pour le sertissage de la plaque collectrice 2 sur le couvercle 1 et le joint d'étanchéité 9 prévu dans la gorge 13 soient un seul et même joint s'étendant sur toute la longueur de la gorge 13 et sur toute la périphérie de la plaque collectrice 2. Bien entendu, on pourra également prévoir que le joint d'étanchéité disposé dans la gorge 13 soit distinct de celui disposé sur le pourtour de la plaque collectrice 2.It may be envisaged that the seal 9 provided for crimping the header plate 2 on the cover 1 and the seal 9 provided in the groove 13 are one and the same seal extending over the entire length of the groove 13 and over the entire periphery of the header plate 2. Of course, it may also be provided that the seal disposed in the groove 13 is distinct from that disposed on the periphery of the header plate 2.
Dans l'exemple choisi pour illustrer l'invention, le module de l'invention comprend deux circuits d'échange de chaleur, donc deux rangées de tubes 3, 4. La rangée de tubes 4 pour laquelle ces derniers présentent les plus petites dimensions, normalement exclusivement en largeur, correspond au circuit à haute température (circuit HT), c'est-à-dire au circuit présentant le fluide dont la chaleur est la plus importante/grande.In the example chosen to illustrate the invention, the module of the invention comprises two heat exchange circuits, thus two rows of tubes 3, 4. The row of tubes 4 for which they have the smallest dimensions, normally exclusively in width, corresponds to the high temperature circuit (HT circuit), that is to say the circuit having the fluid whose heat is the largest / largest.
La cloison longitudinale 5 est ici issue directement du moulage formant l'ensemble du couvercle 1 mais on pourrait bien entendu envisager que cette cloison 5 soit rapportée et fixée au contour (ou périphérie) du couvercle 1. Par ailleurs, comme représenté sur la figure 3 avec un exemple d'une seule et unique cloison transversale/axiale 12, le couvercle 1 selon l'invention pourra comprendre une ou plusieurs cloisons transversales ou axiales 12 destinées à former autant de circuits d'échange de chaleur ou, pour un même circuit, autant de passes que désirées. On choisi ici d'illustrer l'invention avec deux sous-collecteurs 10, 11 qui ne présentent pas des dimensions égales, en l'occurrence le plus petit des deux sous-collecteurs 11 est destiné au circuit haute température. Bien entendu, on pourra prévoir que ces deux sous- collecteurs 10, 11 présentent des dimensions égales, c'est-à-dire notamment que la cloison de répartition 5 s'étende rigoureusement au milieu, ou au centre, du couvercle 1 afin de séparer le collecteur en deux parties identiques.The longitudinal partition 5 is derived directly from the molding forming the entire cover 1, but it could of course be envisaged that this partition 5 be attached and fixed to the contour (or periphery) of the cover 1. Moreover, as shown in FIG. with an example of a single transverse / axial partition 12, the lid 1 according to the invention may comprise one or more transverse or axial partitions 12 intended to form as many heat exchange circuits or, for the same circuit, as many passes as desired. We choose here to illustrate the invention with two sub-collectors 10, 11 which do not have equal dimensions, in this case the smaller of the two sub-collectors 11 is intended for the high temperature circuit. Of course, it can be provided that these two sub-collectors 10, 11 have equal dimensions, that is to say in particular that the distribution partition 5 extends rigorously in the middle, or in the center, of the cover 1 in order to separate the collector into two identical parts.
On notera que chacune des boîtes collectrices 10, 11 sont toujours contiguës, c'est-à-dire que la paroi de partition 5 forme pour chacune 10, 11 une paroi externe. Ainsi, les boîtes collectrices 10, 11, associées l'une à l'autre, présentent un profil semi-circulaire car chacune des boîtes collectrices constitue une partie du profil demi-circulaire de la réunion desdites deux boîtes collectrices 10, 11 ; la réunion des deux chambres collectrices étant constitué par un couvercle unique monobloc 1. Le module d'échanges de chaleur sera idéalement utilisé pour un même fluide caloporteur. Le fluide des différents circuits d'échange de chaleur pourra consister en un mélange d'eau et de glycol, mélange formant « eau de refroidissement » classiquement utilisé pour les moteurs à combustion des véhicules automobiles. L'un et/ou l'autre des deux circuits d'échange de chaleur pourra par exemple être destiné à refroidir le moteur à combustion du véhicule, à refroidir l'huile utilisé par exemple pour la boîte automatique de changement de vitesse ou à refroidir l'air de suralimentation. Note that each of the manifolds 10, 11 are always contiguous, that is to say that the partition wall 5 forms for each 10, 11 an outer wall. Thus, the collector boxes 10, 11, associated with each other, have a semicircular profile because each of the manifolds constitutes part of the semicircular profile of the meeting of said two collector boxes 10, 11; the meeting of the two collector chambers being constituted by a single monoblock cover 1. The heat exchange module will be ideally used for the same heat transfer fluid. The fluid of the various heat exchange circuits may consist of a mixture of water and glycol, a mixture forming "cooling water" conventionally used for combustion engines of motor vehicles. One and / or the other of the two heat exchange circuits may for example be intended to cool the combustion engine of the vehicle, to cool the oil used for example for the automatic gearbox or to cool the air of supercharging.
