Description

Ensemble de deux pièces serties l'une sur l'autre  Set of two pieces set one on the other
L'invention concerne un ensemble de deux pièces serties l'une sur l'autre, un collecteur comprenant ledit ensemble et un échangeur de chaleur comprenant ledit collecteur. The invention relates to a set of two parts crimped on one another, a manifold comprising said assembly and a heat exchanger comprising said collector.
Quoique non exclusivement, les échangeurs thermiques concernés sont destinés à équiper des véhicules et correspondent, dans une application préférentielle, aux condenseurs prévus sur les boucles ou circuits de climatisation des véhicules. Cependant, d'autres applications de ces échangeurs thermiques sont également envisageables sans sortir du cadre de l'invention. Although not exclusively, the heat exchangers concerned are intended to equip vehicles and correspond, in a preferred application, condensers provided on the loops or air conditioning circuits of the vehicles. However, other applications of these heat exchangers are also conceivable without departing from the scope of the invention.
Il est connu des condenseurs comprenant un faisceau de tubes parallèles et deux collecteurs dans lesquels sont raccordées, de façon fixe et étanche, les extrémités correspondantes des tubes. Ainsi, le fluide de la boucle de climatisation, peut circuler d'un collecteur à l'autre, à travers les tubes dans lesquels le fluide passe de la phase vapeur à la phase liquide par échange de chaleur avec un flux d'air, balayant les tubes. Ces échangeurs sont assemblés par brasage. Condensers comprising a bundle of parallel tubes and two collectors are known in which the corresponding ends of the tubes are connected in a fixed and sealed manner. Thus, the fluid of the air conditioning loop, can flow from one manifold to the other, through the tubes in which the fluid passes from the vapor phase to the liquid phase by heat exchange with a flow of air, sweeping the tubes. These exchangers are assembled by soldering.
Les collecteurs comprennent une plaque collectrice à paroi ouverte longitudinalement et un couvercle fermant la plaque collectrice, après brasage. Pour pré-assembler le couvercle et la plaque collectrice avant brasage, il est connu de les sertir. Pour cela, la plaque collectrice possède des bords relevés dont une portion périphérique est sertie autour du couvercle pour fermer le collecteur. The collectors comprise a collector plate with a wall open longitudinally and a cover closing the collector plate after brazing. To pre-assemble the lid and the collector plate before soldering, it is known to crimp them. For this, the collector plate has raised edges, a peripheral portion is crimped around the cover to close the collector.
Ces collecteurs connus présentent l'inconvénient de devoir appliquer à la portion de bord périphérique de la plaque collectrice un effort trop important lors de l'opération de sertissage et de risquer ainsi la déformation du couvercle, ce qui pourra empêcher un brasage correct du couvercle et de la plaque collectrice. These known collectors have the disadvantage of having to apply to the peripheral edge portion of the collector plate excessive force during the crimping operation and thus risk the deformation of the cover, which may prevent proper brazing of the cover and the collector plate.
Une solution pour éviter les problèmes de déformation lors de l'opération de sertissage est d'utiliser une contre forme, nommée « fourchette >> permettant d'empêcher la transmission des efforts de sertissage au couvercle. Une telle solution reste compliquée à mettre en œuvre car nécessitant un outillage spécifique. L'invention a pour but de surmonter les problèmes précités. One solution to avoid the problems of deformation during the crimping operation is to use a counter form, called "fork" to prevent the transmission of crimping forces to the lid. Such a solution remains complicated to implement because requiring specific tools. The object of the invention is to overcome the aforementioned problems.
Elle propose à cet effet un ensemble de deux pièces serties l'une sur l'autre par repliement d'au moins une portion de bord périphérique de l'une, dite première pièce, sur l'autre, dite seconde pièce. Selon l'invention, ladite première pièce présente une zone formant charnière facilitant le repliement de ladite portion de bord périphérique. It proposes for this purpose a set of two pieces crimped one over the other by folding at least a peripheral edge portion of one, said first piece, on the other, said second piece. According to the invention, said first piece has a hinge area facilitating the folding of said peripheral edge portion.
L'effort nécessaire à appliquer sur ladite portion de bord périphérique lors du sertissage de ladite première pièce sur ladite deuxième pièce sera ainsi moins important et réduira le risque de déformation du collecteur. De plus, elle pourra être mis en œuvre sans pièce faisant contre forme. The force required to apply to said peripheral edge portion during crimping of said first piece on said second piece will be less important and reduce the risk of deformation of the collector. In addition, it can be implemented without counterpart parts.
Selon différents modes de réalisation, ladite portion de bord périphérique présente une partie amincie par rapport à une autre partie de la première pièce, destinée à offrir une résistance à la pression d'un fluide. On définit de la sorte ladite zone charnière. According to various embodiments, said peripheral edge portion has a thinned portion relative to another portion of the first piece, intended to provide resistance to the pressure of a fluid. In this way, said hinge zone is defined.
Par exemple, la partie amincie peut s'étendre de ladite zone charnière au bord distal de ladite première pièce. Ladite première pièce présentant une dimension d'extension longitudinale, la partie amincie est, par exemple, continue le long de ladite extension longitudinale. Avantageusement, on peut prévoir une amorce de pliage au niveau de ladite zone charnière, par exemple située au niveau d'une base de ladite partie amincie. For example, the thinned portion may extend from said hinge zone to the distal edge of said first piece. Said first piece having a dimension of longitudinal extension, the thinned portion is, for example, continuous along said longitudinal extension. Advantageously, a folding primer can be provided at said hinge zone, for example located at a base of said thinned portion.
De préférence, ladite partie amincie présente une épaisseur comprise entre 25% et 75% de l'épaisseur de l'autre partie. Preferably, said thinned portion has a thickness between 25% and 75% of the thickness of the other part.
En particulier, elle peut présenter une épaisseur comprise entre 40% et 60% de l'épaisseur de l'autre partie. L'invention concerne aussi un collecteur d'un échangeur de chaleur comprenant une plaque collectrice et un couvercle, ladite plaque collectrice constituant ladite première pièce et ledit couvercle constituant ladite seconde pièce de l'ensemble tel que défini ci-dessus. De préférence, ledit collecteur comprend un couvercle en forme de U avec une base et des ailes longitudinales reliées à la base par une zone incurvée. La zone charnière est en vis-à-vis des ailes, à proximité de la zone incurvée. L'invention concerne également un échangeur de chaleur, notamment condenseur d'un système de climatisation de véhicule automobile, muni d'un collecteur tel que défini ci-dessus. In particular, it may have a thickness of between 40% and 60% of the thickness of the other part. The invention also relates to a collector of a heat exchanger comprising a collector plate and a cover, said collector plate constituting said first part and said cover constituting said second part of the assembly as defined above. Preferably, said manifold comprises a U-shaped lid with a base and longitudinal wings connected to the base by a curved area. The hinge zone is vis-à-vis the wings, near the curved area. The invention also relates to a heat exchanger, including a condenser of a motor vehicle air conditioning system, provided with a collector as defined above.

Figure 2 is a cross section of the collector after crimping the collector plate around the cover.
La figure 3 est une coupe transversale de la plaque collectrice avant l'opération de sertissage. Figure 3 is a cross section of the header plate prior to the crimping operation.
La figure 4 est une vue similaire à la figure 3, illustrant une variante de réalisation. Figure 4 is a view similar to Figure 3, illustrating an alternative embodiment.
L'invention pourra trouver son application dans un échangeur de chaleur tel que représenté sur la figure 1 . Cet échangeur est, par exemple, un condenseur d'une boucle de climatisation de l'habitacle d'un véhicule. The invention can be applied in a heat exchanger as shown in FIG. This exchanger is, for example, a condenser of an air conditioning loop of the passenger compartment of a vehicle.
L'échangeur 1 pourra comprendre, un faisceau de tubes parallèles 2 dont les extrémités 2A sont reliées, de manière fixe et étanche, à des collecteurs ou boîtes collectrices respectivement amont 3 et aval 4 selon le sens de circulation du fluide, notamment du fréon, circulant dans la boucle considérée. A ces collecteurs sont respectivement rapportées des brides de raccordement fluidiques d'entrée 5 et de sortie 6. En particulier, les tubes 2 dans lesquels circule le fluide ont une section transversale oblongue et entre ceux-ci sont agencés des intercalaires 7 augmentant la surface d'échange thermique entre le fluide circulant dans l'échangeur 1 et le flux d'air extérieur traversant celui-ci. L'intérieur des tubes 2 peut aussi inclure des perturbateurs qui, à l'instar des intercalaires, augmentent la surface d'échange thermique et la tenue mécanique des tubes. Il pourra aussi s'agir de tubes extrudés. Chaque tube définit, par exemple, une pluralité de canaux internes, parallèles, de circulation de fluide. Les collecteurs amont 3 et aval 4 sont globalement identiques et ont une forme générale tubulaire. Ils sont de type « bipartite », c'est-à-dire que chacun d'eux se compose d'une plaque collectrice 8 et d'un couvercle 9. The exchanger 1 may comprise a bundle of parallel tubes 2 whose ends 2A are connected, in a fixed and sealed manner, to collectors or manifolds respectively upstream 3 and downstream 4 according to the direction of flow of the fluid, in particular Freon, circulating in the considered loop. To these collectors are respectively reported inlet fluid connection flanges 5 and outlet 6. In particular, the tubes 2 in which the fluid flows have an oblong cross section and between these are arranged spacers 7 increasing the surface area of the fluid. heat exchange between the fluid flowing in the exchanger 1 and the outside air flow therethrough. The inside of the tubes 2 may also include disrupters which, like the spacers, increase the heat exchange surface and the mechanical strength of the tubes. It may also be extruded tubes. Each tube defines, for example, a plurality of internal, parallel, fluid flow channels. The upstream and downstream 3 and 4 collectors are generally identical and have a generally tubular shape. They are of "bipartite" type, that is to say that each of them consists of a collector plate 8 and a cover 9.
L'exemple d'ensemble de deux pièces serties l'une sur l'autre, conforme à l'invention et représenté sur la figure 2 est un collecteur d'échangeur de chaleur tel qu'évoqué ci-dessus. La première pièce représentée est une plaque collectrice 8 et la deuxième, un couvercle 9 desdits collecteurs. The overall example of two pieces crimped to one another, according to the invention and shown in Figure 2 is a heat exchanger collector as evoked above. The first part shown is a header plate 8 and the second, a cover 9 of said manifolds.
La plaque collectrice 8 a, par exemple, une section transversale sensiblement en U et sa paroi définit ainsi un fond 1 1 prolongé de deux branches ou ailes latérales 14, parallèles, dont l'extrémité distale des bords périphériques délimitent une ouverture longitudinale 15 obturée par le couvercle sur la figure. Dans le fond 1 1 de la plaque collectrice 8 sont ménagées des fentes oblongues 18 tout du long de celui-ci, dans lesquelles sont reçues les extrémités correspondantes des tubes parallèles 2. Elles pourront être bordées de collets 30. The collecting plate 8 has, for example, a substantially U-shaped cross-section and its wall thus defines a bottom 1 1 extended by two parallel branches or side wings 14, the distal end of the peripheral edges delimiting a longitudinal opening 15 closed by the lid on the figure. In the bottom 1 1 of the header plate 8 are formed oblong slots 18 all along thereof, in which are received the corresponding ends of the parallel tubes 2. They may be flanked by collars 30.
Le couvercle 9 présente, par exemple, lui aussi, une section transversale en U dont la paroi 20 forme un fond légèrement concave 21 prolongé par des branches ou ailes latérales 22, parallèles, plus courtes que celles de la plaque collectrice 8. La dimension, notamment en largeur du couvercle, est telle que les branches latérales 22 s'ajustent tête-bêche entre les branches latérales 14 de la plaque collectrice 8. The cover 9 has, for example, also a U-shaped cross section whose wall 20 forms a slightly concave bottom 21 extended by parallel branches or side wings 22, shorter than those of the collecting plate 8. The dimension, in particular in width of the lid, is such that the lateral branches 22 fit head to tail between the lateral branches 14 of the header plate 8.
L'assemblage du couvercle 9 et de la plaque collectrice 8 définit un espace interne 24 dans lequel est amené à circuler le fluide de la boucle. De par la forme emboîtée des U de la plaque 8 et du couvercle 9, la section transversale du collecteur 3 ou 4 est approximativement rectangulaire, mais pourrait être différente. Des cloisons, non représentées, sont éventuellement prévues à chacune des extrémités longitudinales du collecteur pour fermer le collecteur. Des cloisons intermédiaires, pouvant rendre deux parties du collecteur hermétiques l'une de l'autre peuvent également être prévues. Ces cloisons comprennent par exemple, une butée pour le positionnement du couvercle 9. The assembly of the cover 9 and the manifold plate 8 defines an internal space 24 in which is circulated the fluid of the loop. Due to the nested shape of the U of the plate 8 and the cover 9, the cross section of the collector 3 or 4 is approximately rectangular, but could be different. Partitions, not shown, are optionally provided at each of the longitudinal ends of the collector to close the collector. Intermediate partitions, which can make two parts of the collector hermetic to one another can also be provided. These partitions comprise, for example, a stop for positioning the cover 9.
Si l'on se reporte à nouveau à la figure 1 , on peut voir que les brides d'entrée 5 et de sortie 6 sont prévues sur respectivement les collecteurs amont et aval. Les deux brides 5, 6 notamment dans le cas de collecteurs à cloisons de séparation internes pourraient se trouver sur le même collecteur tubulaire 5 respectivement aux extrémités de celui-ci, comme le montre la bride 6 en trait pointillé sur la figure 1 . La fonction des brides d'entrée 5 et de sortie 6 est d'assurer les connexions fluidiques via des conduites non représentées entre, dans l'exemple, un compresseur de la boucle en question, tourné vers le collecteur amont 3 et l'espace intérieur du collecteur amont tubulaire 3, et entre l'espace intérieur 24 du collecteur aval tubulaire 4 et un détendeur tourné vers celui-ci, via des passages de fluide ménagés dans les brides. Referring again to Figure 1, it can be seen that the inlet flanges 5 and outlet 6 are provided on the upstream and downstream collectors respectively. The two flanges 5, 6 especially in the case of collectors with internal partition walls could be on the same tubular collector 5 respectively at the ends thereof, as shown by the flange 6 dotted line in Figure 1. The function of the inlet and outlet flanges 6 is to ensure the fluidic connections via unrepresented ducts between, in the example, a compressor of the loop in question, facing the upstream collector 3 and the interior space. tubular upstream collector 3, and between the inner space 24 of the tubular downstream collector 4 and an expander turned towards it, via fluid passages in the flanges.
Pour information, on a représenté, par la référence 35, d'autres brides rapportées par sertissage sur les collecteurs tubulaires 3, 4 et destinées à la fixation de l'échangeur 1 sur des supports appropriés du véhicule et/ou à l'accrochage d'une bouteille de stockage de fluide en communication de fluide avec l'un des collecteurs. For information, there is shown, by reference 35, other flanges reported by crimping on the tubular collectors 3, 4 and intended for fixing the exchanger 1 on appropriate supports of the vehicle and / or the attachment of a fluid storage bottle in fluid communication with one of the collectors.
Une telle bouteille, par exemple raccordée au collecteur aval, a pour but d'assurer la filtration et la déshydratation du fluide frigorigène, de compenser les variations de volume du fluide frigorigène et/ou d'assurer la séparation de la portion de fluide qui pourrait être encore en phase gazeuse à la sortie du condenseur de la portion de fluide en phase liquide. L'opération de sertissage pourra permettre de pré-assembler non seulement la plaque collectrice 8 et le couvercle 9, mais aussi les brides d'entrées 5 et de sorties 6 des fluides, les brides 35 destinées à la fixation de l'échangeur 1 sur des supports appropriés du véhicule et/ou à l'accrochage de la bouteille de stockage de fluide. Ces éléments sont sertis, par exemple, entre le couvercle 9 et la portion de bord périphérique 12 de la plaque collectrice 8. On obtient de la sorte un pré-assemblage de tous ces éléments en une seule opération. Such a bottle, for example connected to the downstream collector, is intended to ensure the filtration and dehydration of the refrigerant, to compensate for the variations in the volume of the refrigerant and / or to ensure the separation of the fluid portion that could still be in the gas phase at the condenser outlet of the liquid phase fluid portion. The crimping operation may allow to pre-assemble not only the manifold plate 8 and the cover 9, but also the inlet flanges 5 and the fluid outlet flanges 6, the flanges 35 intended for the attachment of the exchanger 1 to appropriate supports of the vehicle and / or attachment of the fluid storage bottle. These elements are crimped, for example, between the cover 9 and the peripheral edge portion 12 of the collector plate 8. In this way, a pre-assembly of all these elements is obtained in a single operation.
La figure 2 illustre plus généralement un ensemble de deux pièces serties l'une sur l'autre par repliement d'au moins une portion de bord périphérique 12 de l'une dite première pièce, ici la plaque collectrice 8, sur l'autre dite seconde pièce, ici le couvercle 9. Dans l'exemple illustré, la portion de bord périphérique 12, destinée à être sertie, est située au niveau d'une extrémité libre des ailes latérales 14 de la plaque collectrice 8. FIG. 2 more generally illustrates a set of two pieces crimped on one another by folding at least one peripheral edge portion 12 of a said first piece, here the collecting plate 8, on the other said second part, here the cover 9. In the illustrated example, the peripheral edge portion 12, intended to be crimped, is located at a free end of the lateral flanges 14 of the header plate 8.
Selon l'invention, le sertissage de la portion de bord périphérique 12 de ladite première pièce 8 sur la deuxième pièce 9 est facilité par la présence d'une zone charnière 16 sur ladite première pièce 8. According to the invention, the crimping of the peripheral edge portion 12 of said first piece 8 on the second piece 9 is facilitated by the presence of a hinge zone 16 on said first piece 8.
L'effort nécessaire sera donc moins important pour sertir ladite portion de bord périphérique 12 de ladite première pièce 8 sur ladite deuxième pièce 9. Cela permettra non seulement de réduire le risque de déformation du collecteur mais aussi d'éviter l'utilisation de pièce faisant contre forme. The force required will be less important to crimp said peripheral edge portion 12 of said first part 8 of said second part 9. This will not only reduce the risk of deformation of the collector but also to avoid the use of part making against form.
En outre, dans le cas d'un pré-assemblage plus complet où la bouteille est pré-assemblée entre la plaque collectrice et le couvercle pour être sertie en même temps qu'eux, l'étroitesse entre le couvercle et la bouteille implique l'utilisation de lames de sertissage de faible section donc cassante. En réduisant l'effort nécessaire au sertissage de ladite portion de bord périphérique 12 de ladite première pièce 8 sur ladite deuxième pièce 9 on réduit également le risque de casse des lames de sertissage de faible section. De préférence, mais non exclusivement, le sertissage est facilité par l'amincissement de tout ou partie de ladite portion de bord périphérique 12 de la première pièce 8 par rapport à une autre partie 14 de la première pièce, destinée à offrir une résistance à la pression d'un fluide, ici le reste des ailes latérales 14 et le fond 1 1 de la plaque collectrice 8. L'amincissement de paroi est obtenu par toute opération mécanique appropriée (laminage, étirage, emboutissage, etc.). In addition, in the case of a more complete pre-assembly where the bottle is pre-assembled between the collector plate and the lid to be crimped together with them, the narrowness between the lid and the bottle involves the use of crimping blades of small section thus brittle. By reducing the effort required to crimp the said portion of peripheral edge 12 of said first piece 8 on said second piece 9 is also reduced the risk of breakage crimping blades small section. Preferably, but not exclusively, crimping is facilitated by the thinning of all or part of said peripheral edge portion 12 of the first piece 8 relative to another portion 14 of the first piece, intended to provide resistance to the pressure of a fluid, here the rest of the lateral wings 14 and the bottom 1 1 of the collector plate 8. The wall thinning is obtained by any appropriate mechanical operation (rolling, drawing, stamping, etc.).
Autrement dit, la portion de bord périphérique 12, destinée au sertissage, présente une partie amincie 13, c'est-à-dire, une partie dont l'épaisseur de matière est plus faible que l'épaisseur de matière au niveau d'une partie de la première pièce, destinée à résister à la pression du fluide. Dans l'exemple illustré, la partie amincie 13 présente une épaisseur inférieur à celle du reste des ailes latérales 14 et/ou du fond 1 1 de la plaque collectrice 8. In other words, the peripheral edge portion 12, intended for crimping, has a thinned portion 13, that is to say, a part whose thickness of material is smaller than the thickness of material at a part of the first part, intended to resist the pressure of the fluid. In the example illustrated, the thinned portion 13 has a thickness less than that of the rest of the lateral wings 14 and / or the bottom 1 1 of the header plate 8.
La figure 3 nous présente une vue en coupe de la première pièce 8 avant sertissage de la portion de bord périphérique 12 autour de la deuxième pièce 9. Dans cet exemple, la partie amincie 13 s'étend de la zone charnière au bord distal de la première pièce. Autrement dit, elle couvre l'ensemble de la portion 12 destinée au sertissage. FIG. 3 shows a sectional view of the first piece 8 before crimping the peripheral edge portion 12 around the second piece 9. In this example, the thinned portion 13 extends from the hinge zone to the distal edge of the first piece. In other words, it covers the entire portion 12 for crimping.
La partie amincie 13 peut, dans le cas où, comme dans l'exemple illustré, la première pièce présente une dimension d'extension longitudinale, être continue le long de ladite dimension d'extension longitudinale. The thinned portion 13 may, in the case where, as in the example illustrated, the first piece has a dimension of longitudinal extension, be continuous along said longitudinal extension dimension.
La figure 4 nous illustre un exemple facilitant d'avantage encore le repliement par sertissage de la portion de bord périphérique 12 de la première pièce 8 sur la deuxième pièce 9 en ajoutant au niveau de la zone de sertissage 16, une amorce de pliage 17. Cette amorce de pliage 17 se situe par exemple du coté intérieur de ladite première pièce 8. Pour faciliter au mieux le repliement par sertissage de la portion de bord de périphérie 12 de la première pièce 8 sur la deuxième pièce 9 sans risquer sa casse, il est prévu que la partie amincie 13 de ladite portion de bord périphérique 12 présente une épaisseur comprise, par exemple, entre 25% et 75% de l'épaisseur de l'autre partie. FIG. 4 illustrates an example which further facilitates crimping folding of the peripheral edge portion 12 of the first piece 8 on the second piece 9 by adding at the crimping zone 16, a folding primer 17. This folding primer 17 is for example the inner side of said first piece 8. To facilitate the best folding by crimping the periphery edge portion 12 of the first piece 8 on the second piece 9 without risk of breaking, it is expected that the thinned portion 13 of said peripheral edge portion 12 has a thickness of, for example, between 25% and 75% of the thickness of the other part.
Plus précisément il est prévu que la partie amincie 13 de la portion de bord périphérique 12 présente une épaisseur comprise entre 40% et 60% de l'épaisseur de l'autre partie, notamment environ 50% Dans le cas où, comme illustré, l'ensemble de deux pièces serties l'une sur l'autre est un collecteur dont le couvercle 9 est en forme de U avec une base 21 et des ailes longitudinales 22 reliées à la base par une zone incurvée 23, la zone charnière 16, ici la base de la zone amincie 13, peut se situer en vis-à-vis des ailes longitudinales 22, à proximité de la zone incurvée 23. Autrement dit, la zone charnière 16 est plus proche de la zone incurvée du couvercle 9 que du bord opposé desdites ailes 22. More specifically it is expected that the thinned portion 13 of the peripheral edge portion 12 has a thickness of between 40% and 60% of the thickness of the other portion, in particular about 50%. set of two pieces crimped one on the other is a collector whose lid 9 is U-shaped with a base 21 and longitudinal wings 22 connected to the base by a curved zone 23, the hinge zone 16, here the base of the thinned zone 13 may be situated opposite the longitudinal wings 22, close to the curved zone 23. In other words, the hinge zone 16 is closer to the curved zone of the cover 9 than to the edge opposite of said wings 22.
