Abstract
Description
La présente invention concerne un échangeur thermique et a pour objet un échangeur de construction simple, compacte et économique. The present invention relates to a heat exchanger and relates to an exchanger of simple, compact and economical construction.
L'invention concerne plus particulièrement des échangeurs dans lesquels la surface d'échange est constituée par des tales minces embouties, soudées et présentant des ondulations permettant aux tôles de s'appuyer les unes sur les autres tout en conservant un espace libre pour les fluides malgré les efforts dfls aux pressions. Le formage par explosion permet de réa liser des tôles unitaires de très grandes dimensions, plusieurs dizaines de m2 par tôle, autorisant la réalisation d'échangeurs de très grandes surfaces et d'ef- ficacité très élevée. The invention relates more particularly to exchangers in which the exchange surface is constituted by stamped thin sheets, welded and having corrugations allowing the sheets to rest on each other while retaining a free space for the fluids despite efforts due to pressures. Explosion forming makes it possible to produce unitary sheets of very large dimensions, several tens of m2 per sheet, allowing the production of exchangers of very large surfaces and of very high efficiency.
Les tales sont soudées ensemble sur le pourtour, en laissant des ouvertures appropriées pour les entrées et les sorties de fluide, et des bottes de raccordement sont également soudées sur les bords des tales empilées, en regard de ces entrées et sorties de fluides,
On a constaté que la réalisation de ces soudures est une opération délicate et qutil est difficile d'obte- nir une étanchéité satisfaisante, tant entre les tales, qu'aux joints des bottes de raccordement. Les fluides circulant entre les tales, pouvant ttre à une pression supérieure à l'ambiance, il faut prévoir des moyens pour maintenir serré ltempilement et csest une autre difficulté rencontrée dans la réalisation de ces échangeurs, de maintenir des tales à la forme générale plane.The tabs are welded together around the periphery, leaving openings suitable for the inlets and outlets of fluid, and connection boots are also welded on the edges of the stacked tales, facing these inlets and outlets of fluids,
It has been found that making these welds is a delicate operation and that it is difficult to obtain a satisfactory seal, both between the tabs and at the joints of the connection boots. The fluids circulating between the plates, being able to be at a pressure higher than the ambient, it is necessary to provide means for keeping tight the stack and this is another difficulty encountered in the production of these exchangers, to maintain plates with a generally flat shape.
L'invention a pour objet un échangeur du type ci-dessus, qui permet avec une construction facile, dtobo tenir des liaisons solides et une bonne étanchéité. The invention relates to an exchanger of the above type, which allows with easy construction, dtobo hold solid connections and good sealing.
Selon une caractéristique de l'invention, l'ensemble est constitué par un empilage de tales soudées sur le pourtour par ltintermédiaire de de barrettes assurant ltespacement entre plaques, interrompues pour permettre les entrées et sorties des fluides. Les barrettes en metal, de préférence le mEme métal que les tales minces, ont une épaisseur correspondant à l'écart entre deux tables adjacentes et sont disposées sur le pourtour de ltem- pilage, entre les tales, sauf aux endroits correspondant aux entrées et sorties de fluides, et l'on soude ensemble le bord des tales et les barrettes. Les soudures sont beaucoup plus faciles à réaliser, assurent une bonne résistance et sont étanches.De plus, il est beaucoup plus facile de souder les bottes de raccordement pour les entrées et les sorties des fluides0
Selon une autre caractéristique de l'invention, l'empilage de tales formant l'échangeur est disposé dans une enveloppe cylindrique, résistant à la pression, et l'on met en pression l'enceinte extérieure à ltempilement de tales par mise en communication avec 11 entrée du fluide ayant la plus forte pression0 Ceci permet de maintenir les différentes tales (lisses et embouties) au contact sur la totalité de leur surface sans dispositif mécanique. On réalise ainsi le logement de ltéchangeur formé de plaques empilées dans une enveloppe cylindrique, assurant la reprise des efforts de pression du fluide compris entre cette enveloppe cylindrique et ltéchan- geur.According to a characteristic of the invention, the assembly is constituted by a stack of sheets welded around the perimeter by means of bars ensuring the spacing between plates, interrupted to allow the inflows and outflows of the fluids. The metal bars, preferably the same metal as the thin sheets, have a thickness corresponding to the distance between two adjacent tables and are arranged around the perimeter of the pile, between the sheets, except at the places corresponding to the inputs and outputs fluids, and the edges of the blades and the bars are welded together. The welds are much easier to make, provide good resistance and are waterproof, and it is much easier to weld the connection boots for the inputs and outputs of fluids.
According to another characteristic of the invention, the stack of sheets forming the exchanger is arranged in a cylindrical envelope, resistant to pressure, and the external enclosure is pressurized by stacking sheets by placing in communication with 11 entry of the fluid with the highest pressure0 This keeps the different tales (smooth and pressed) in contact over their entire surface without mechanical device. This produces the housing of the exchanger formed of plates stacked in a cylindrical envelope, ensuring the resumption of the pressure forces of the fluid comprised between this cylindrical envelope and the exchanger.
La description qui va suivre, en regard des dessins annexes, donnée à titre d'exemple non limitatif, fera bien comprendre comment ltinvention peut titre réalisée
la figure I est une vue en coupe partielle dtun mode de réalisation dtun échangeur selon ltinven- tison. The description which follows, with reference to the accompanying drawings, given by way of nonlimiting example, will make it clear how the invention can be carried out.
Figure I is a partial sectional view of an embodiment of a heat exchanger according to the invention.
La figure 2 est une vue analogue à la figure 1 pour un autre mode de réalisation. Figure 2 is a view similar to Figure 1 for another embodiment.
La figure 3 est une vue schématique en perspective dtun échangeur selon l'invention, les bottes de raccordement étant supposées transparentes. Figure 3 is a schematic perspective view of an exchanger according to the invention, the connection boots being assumed to be transparent.
La figure 4 est une vue schématique repré sentant la disposition d'ensemble dtun échangeur selon l'invention à deux passes,
La figure 5 est une vue analogue à la figure 4 pour un échangeur à trois passes.FIG. 4 is a schematic view representing the overall arrangement of a heat exchanger according to the invention with two passes,
Figure 5 is a view similar to Figure 4 for a three pass exchanger.
La figure 6 représente une autre disposition d'échangeur à trois passes. Figure 6 shows another three pass heat exchanger arrangement.
L'échangeur de la figure 1 comporte un empilage de tales : une sur deux est une ttle plane 11, et entre deux ttles planes est disposée une ttle 12 présentant des ondulations ou des reliefs sur les deux faces : des reliefs 13 vers le haut et des reliefs 14 vers le bas. Sur les bords de l'empilage, des barrettes 15 maintiennent les tales à l'écartement correspondant aux reliefs des tôles. Les tales et les barrettes sont soudées pour obtenir la solidité de l'assemblage et l'étanchéité aux fluides qui traversent ltéchangeur. The exchanger of FIG. 1 comprises a stack of plates: one in two is a flat head 11, and between two flat heads is arranged a head 12 having undulations or reliefs on the two faces: reliefs 13 upwards and reliefs 14 downwards. On the edges of the stack, bars 15 hold the plates at the spacing corresponding to the reliefs of the sheets. The plates and the bars are welded to obtain the solidity of the assembly and the impermeability to the fluids which pass through the exchanger.
Dans la variante de la figure 2, toutes les ttles ont la même forme et comportent des déformations 16 formant des reliefs sur la mtme face. Les déformations sont décalées ou tracées suivant des angles différents pour ne pas stemboSter les unes dans les autres, afin d'assurer les écarts voulus entre les tales. Sur les bords, les barrettes sont disposées et soudées de la même façon que sur la figure 1. In the variant of FIG. 2, all the ttles have the same shape and include deformations 16 forming reliefs on the same face. The deformations are offset or traced at different angles so as not to stemboSter into each other, to ensure the desired gaps between the tales. On the edges, the bars are arranged and welded in the same way as in Figure 1.
L'échangeur de la figure 3 comporte quatre niveaux de circulation de fluide, délimités par cinq tales 21, 22, 23, 24 et 25, séparées par des barrettes 27, 28, 29 et 30. Bien entendu, en pratique, il pourra y avoir un nombre de tales très supérieur, le principe restant le même. Les tôles sont rectangulaires et la circulation des fluides se fait suivant la grande dimension. Ceci ngest qurun exemple, La forme rectangulaire est avantageuse en pratique, mais nullement nécessaire selon la présente invention.Dans les niveaux correspondant aux barrettes 27 et 29, le fluide circule par exemple de la gauche vers la droite sur la figure, et pénètre dans ltéchangeur par la moitié verticale gauche de l'empilage, les barrettes 27 et 29 étant interrompues sur la moitié gauche du petit cité, pour l'entrée, et sur une moitié du c8té opposé pour la sortie du fluide. The exchanger of FIG. 3 has four levels of fluid circulation, delimited by five plates 21, 22, 23, 24 and 25, separated by bars 27, 28, 29 and 30. Of course, in practice, there may be have a very higher number of tales, the principle remaining the same. The sheets are rectangular and the circulation of fluids takes place along the large dimension. This is only an example. The rectangular shape is advantageous in practice, but not at all necessary according to the present invention. In the levels corresponding to the bars 27 and 29, the fluid circulates for example from left to right in the figure, and enters the exchanger by the left vertical half of the stack, the bars 27 and 29 being interrupted on the left half of the small city, for the inlet, and on one half of the opposite side for the outlet of the fluid.
On a représenté schématiquement les bottes de raccordement 31, 32, 33 et 34, les bottes 31 et 32 étant supposées transparentes pour laisser voir les ouvertures d'entrée et de sortie des fluides. Les bottes de raccordement ont la forme de demi-oylindre, de section droite elliptique par exemple, obturée en haut et en bas par des éléments plans, et chaque botte est soudée à l'empilage suivant deux génératrices verticales.Cette soudure est facilitée ; il en résulte une très bonne solidité et étanchéité grâce à la présence des barrettes0
Comme les fluides traversant ltéchangeur peuvent titre à une pression supérieure à l'atmosphère, les différents fluides pouvant ttre à des pressions dif férentes, il est prévu selon L'invention de placer l'em- pilement à l'intérieur d'une enceinte étanche, dont le volume est mis en communication avec le circuit de fluide dont la pression est la plus forte. Ceci permet de maintenir les différentes tales (lisses et embouties) au contact sur toute leur surfacez sans aucun dispositif mécanique.The connection boots 31, 32, 33 and 34 are shown diagrammatically, the boots 31 and 32 being assumed to be transparent so as to reveal the inlet and outlet openings for the fluids. The connection boots are in the form of a half-cylinder, of elliptical cross section for example, closed at the top and bottom by planar elements, and each boot is welded to the stack according to two vertical generators. This welding is facilitated; this results in very good solidity and tightness thanks to the presence of the bars0
As the fluids passing through the exchanger can be at a pressure higher than the atmosphere, the different fluids being able to be at different pressures, it is provided according to the invention to place the stack inside a sealed enclosure , whose volume is placed in communication with the fluid circuit whose pressure is the highest. This keeps the different tales (smooth and pressed) in contact over their entire surface without any mechanical device.
La figure 4 représente schématiquement un tel -échangeur. Ltempilage 26, avec les bottes de raccordement 31, 32, 33 et 34, est placé à l'intérieur d'une enveloppe cylindrique 35 assurant la reprise des efforts de pression du fluide compris entre cette enveloppe cylindrique et l'échangeur. n premier fluide rentre dans l'empilement par la conduite 37 et sort par la conduite 38, tandis qu'un second fluide, traversant l'échangeur à contre-courant, entre par la conduite 39 et sort par la conduite 41. L'ensemble parallélépipédique tient en pression car on applique à l'extérieur de cet ensemble une pression supérieure ou égale à celle du fluide le plus comprimé, Si la pression utilisée est la pression dudit fluide, on mettra en communication l'enceinte et ledit fluide par une prise de pression située en amont de l'échangeur proprement dit, de façon à ce que la pression dans la calandre soit toujours supérieure à la pression dans les passes, la différence de pression étant due à la perte de charge de la matrice de ltéchan- gour. Figure 4 shows schematically such a heat exchanger. The stack 26, with the connection boots 31, 32, 33 and 34, is placed inside a cylindrical envelope 35 ensuring the resumption of the pressure pressures of the fluid comprised between this cylindrical envelope and the exchanger. n first fluid enters the stack via line 37 and exits via line 38, while a second fluid, passing through the countercurrent exchanger, enters via line 39 and leaves via line 41. The assembly parallelepipedic holds pressure because outside of this assembly is applied a pressure greater than or equal to that of the most compressed fluid, If the pressure used is the pressure of said fluid, the enclosure and said fluid will be brought into communication by a socket pressure located upstream of the exchanger itself, so that the pressure in the calender is always higher than the pressure in the passes, the pressure difference being due to the pressure drop of the ltéchan- gour matrix .
La prise de pression pourra avantageusement titre une prise de pression totale. Les boîtes de raccordement des passes de l'échangeur sont reliées à l'extérieur de l'enceinte par des tuyauteries pouvant être équipées de soufflets pour pallier les problèmes de dilastation éventuels
En supposant que le premier fluide soit à une pression supérieure à celle du second, une ouverture est prévue en 42 dans la conduite 37 pour que le circuit du premier fluide communique avec l'intérieur de l'enceinte et que la pression qui y règne soit celle du premier fluide dans son circuit. L'empilement est solidaire de enceinte au moyen d'entretoises 45, 46, etc, montées de façon à permettre le jeu de dilatation thermique, comme il est bien connu dans la technique.The pressure tap can advantageously be taken as a total pressure tap. The junction boxes of the exchanger passes are connected to the outside of the enclosure by pipes which can be fitted with bellows to alleviate possible dilation problems.
Assuming that the first fluid is at a pressure higher than that of the second, an opening is provided at 42 in line 37 so that the circuit of the first fluid communicates with the interior of the enclosure and that the pressure which prevails there is that of the first fluid in its circuit. The stack is integral with the enclosure by means of spacers 45, 46, etc., mounted so as to allow the thermal expansion clearance, as is well known in the art.
Les tuyauteries 37, 38, 39 et 41 sont normalement soudées à ltenveloppe cylindriquep et pour per- mettre le jeu de dilatation, on prévoit les soufflets 48 et 49 sur les conduites 38 et 39. The pipes 37, 38, 39 and 41 are normally welded to the cylindrical envelope and to allow the expansion clearance, the bellows 48 and 49 are provided on the pipes 38 and 39.
La distribution des fluides peut se faire de plusieurs manières différentes. Au lieu des deux bottes soudées aux extrémités du faisceau, et intérieures à 11 enceinte, une botte peut autre supprimée et le fluide arrive dans une passe à travers la calandre. The distribution of fluids can be done in several different ways. Instead of the two boots welded to the ends of the bundle, and inside the enclosure, a boot can be removed and the fluid arrives in a pass through the grille.
Un tel échangeur peut comporter plus de deux passes. La figure 5 représente, de façon analogue à la figure 4, un échangeur à trois passes0 Pour simplifier, on n'a pas représenté les entretoises, ni les soufflets, ni la prise de pression0 La figure 6 représente une autre disposition à trois passes A, B et C. Comme on l'a déjà indiqué, l'empilement peut avoir une forme autre que rectangulaire, les courants peuvent titre inverses, parallèles, croisés, etcO
Il va de soi que les modes de réalisation dé- crits ne sont que des exemples et qu'il serait possible de les modifier, notamment par substitution d'équiYz- lents techniques, sans sortir pour cela du cadre de l'invention. Such an exchanger can have more than two passes. FIG. 5 represents, in a similar manner to FIG. 4, a three-pass exchanger0 For simplicity, the spacers, the bellows, and the pressure tap have not been shown. FIG. 6 represents another arrangement with three passes A , B and C. As already indicated, the stack can have a shape other than rectangular, the currents can title reverse, parallel, crossed, etcO
It goes without saying that the embodiments described are only examples and that it would be possible to modify them, in particular by substitution of technical equivalents, without departing from the scope of the invention.
