Description

Collecteur pour échangeur de chaleur Collector for heat exchanger
La présente invention concerne un collecteur pour échangeur de chaleur ainsi qu'un échangeur de chaleur équipé d'un tel collecteur et un procédé d'assemblage associé . The present invention relates to a collector for heat exchanger and a heat exchanger equipped with such a collector and a method of assembly associated.
L'invention trouvera, notamment, ses applications dans le domaine des condenseurs pour les dispositifs de chauffage ou de refroidissement de véhicules automobiles.  The invention will find, in particular, its applications in the field of condensers for heating or cooling devices of motor vehicles.
Toutefois bien que particulièrement prévu pour une telle application 1 ' échangeur pourra être utilisé dans d'autres domaines utilisant des échangeurs comportant des collecteurs en deux parties.  However, although particularly intended for such an application, the exchanger may be used in other fields using exchangers comprising two-part collectors.
ARRIERE PLAN DE L'INVENTION  BACKGROUND OF THE INVENTION
On utilise, dans certains échangeurs de chaleur, un type de collecteur en deux parties dit collecteur bipartite ou boîte à fluide bipartite.  In some heat exchangers, a two-part type collector called bipartite collector or bipartite fluid box is used.
Plus précisément ce type de collecteur comporte une première partie inférieure ou plaque collectrice qui comprend un fond et des parois longitudinales.  More specifically, this type of collector comprises a first lower part or collector plate which comprises a bottom and longitudinal walls.
Ce type de collecteur comporte également une partie supérieure formant un couvercle, cette partie supérieure venant recevoir des brides formant entrée et/ou sortie pour un fluide traversant l' échangeur et/ou des brides formant pattes de fixation permettant la fixation de l' échangeur sur un support .  This type of collector also comprises an upper part forming a cover, this upper part coming to receive flanges forming an inlet and / or outlet for a fluid passing through the exchanger and / or flanges forming fixing lugs allowing the attachment of the exchanger to a support .
Un échangeur de chaleur à tubes comprend généralement un ou deux collecteurs dont la partie inférieure comporte des fentes parallèles pour la réception des extrémités des tubes dans lesquels circule le fluide traversant l' échangeur, ledit fluide débouchant par l'extrémité desdits tubes dans un volume intérieur du collecteur .  A tube heat exchanger generally comprises one or two collectors, the lower part of which has parallel slots for receiving the ends of the tubes in which the fluid passing through the exchanger circulates, said fluid opening through the end of said tubes into an interior volume. of the collector.
Les différents composants de 1 ' échangeur sont généralement métalliques, notamment en alliage d'aluminium, et sont assemblés par brasage. Pour assurer une bonne qualité de brasage, il est nécessaire d'assembler préalablement les composants entre eux, de façon précise. The various components of the exchanger are generally metallic, especially aluminum alloy, and are assembled by brazing. To ensure good quality brazing, it is necessary to assemble the components beforehand, precisely.
Ainsi, l'assemblage d'un échangeur de chaleur comporte de nombreuses étapes préalables d'assemblage. Dans le cas d'un collecteur bipartite on réalise notamment en plus de l'assemblage des tubes métalliques, un premier assemblage entre les parties inférieure et supérieure du collecteur, un second assemblage entre les brides d'entrée/sortie et la partie supérieure du collecteur et un troisième assemblage entre la partie supérieure et les différentes pattes de fixation.  Thus, the assembly of a heat exchanger comprises many preliminary assembly steps. In the case of a bipartite collector, in addition to the assembly of the metal tubes, a first connection is made between the lower and upper portions of the collector, a second connection between the inlet / outlet flanges and the upper part of the collector. and a third assembly between the upper part and the different fixing lugs.
Ces différents assemblages nécessitent deux ou trois étapes selon les modes d'assemblage connus de l'homme du métier ; le procédé d'assemblage de l' échangeur est donc complexe d'autant que les assemblages empruntent à des technologies différentes notamment de sertissage, de clinchage ou encore de soudage.  These different assemblies require two or three steps according to the assembly methods known to those skilled in the art; the assembly method of the exchanger is therefore complex especially as the assemblies use different technologies including crimping, clinching or welding.
On connaît ainsi un premier mode d'assemblage dans lequel le couvercle est serti par des agrafes prévues au niveau de la partie inférieure, la bride d' entrée/sortie est quant à elle maintenue par évasement d'un collet du couvercle et la patte est fixée par une agrafe de la patte traversant la paroi du couvercle.  Thus, a first method of assembly is known in which the cover is crimped by clips provided at the bottom, the inlet / outlet flange is maintained by flaring a collar of the cover and the tab is fixed by a clip of the tab through the wall of the lid.
On connaît également un second mode d'assemblage dans lequel le couvercle est également serti sur la partie inférieure à l'aide d'agrafes disposées sur la partie inférieure, tandis que la bride d' entrée/sortie est sertie par une agrafe disposée sur le couvercle et que la patte de fixation est rapportée sur le couvercle au moyen d'une soudure de type TIG.  A second method of assembly is also known in which the lid is also crimped on the lower part by means of staples arranged on the lower part, while the inlet / outlet flange is crimped by a clip disposed on the cover and that the fixing lug is attached to the cover by means of a TIG type weld.
On connaît également un troisième mode d'assemblage dans lequel le couvercle est serti dans la partie inférieure du collecteur tandis que la bride d'entrée/sortie et la patte de fixation sont rendus solidaires du couvercle par des opérations de clinchage. A third method of assembly is also known in which the cover is crimped into the lower part of the manifold while the flange input / output and the bracket are secured to the lid by clinching operations.
OBJET DE L'INVENTION  OBJECT OF THE INVENTION
La présente invention a pour objet de proposer un échangeur de chaleur dont la structure des différents composants permet un assemblage de la partie inférieure du collecteur et du couvercle ainsi qu'au moins de la ou des brides d' entrée/sortie et/ou de la ou des pattes de fixation en une seule opération de sertissage dès lors que les composants précités ont été positionnés les uns par rapport aux autres .  The object of the present invention is to propose a heat exchanger whose structure of the various components makes it possible to assemble the lower part of the collector and the cover as well as at least the inlet / outlet flange (s) and / or the or fastening lugs in a single crimping operation when the aforementioned components have been positioned relative to each other.

La partie inférieure 3 forme la base du collecteur 2 et comprend un fond 5, des parois longitudinales 6 terminées par des bords longitudinaux 7, par exemple rectilignes, et des parois transversales 8.  The lower part 3 forms the base of the collector 2 and comprises a bottom 5, longitudinal walls 6 terminated by longitudinal edges 7, for example rectilinear, and transverse walls 8.
La partie supérieure 4 forme le couvercle du collecteur 2. Les dimensions du couvercle 4 sont conçues pour permettre l'insertion et la réception du couvercle 4 entre les parois longitudinales 6, lorsque les bords longitudinaux 7 sont en position droite.  The upper part 4 forms the cover of the collector 2. The dimensions of the cover 4 are designed to allow insertion and reception of the cover 4 between the longitudinal walls 6, when the longitudinal edges 7 are in the upright position.
L'échangeur 1 comprend en outre deux brides d'entrée/sortie de fluide 9 permettant chacune la réception d'une conduite de fluide (non représentée dans les figures annexées) .  The exchanger 1 further comprises two fluid inlet / outlet flanges 9 each allowing the reception of a fluid line (not shown in the accompanying figures).
L'échangeur 1 comprend également deux autres brides formant deux pattes de fixation 10. Ces pattes de fixation 10 permettent d'assurer la fixation de l'échangeur 2 sur un support (non représenté dans les figures annexées) , selon diverses possibilités de fixation bien connues de l'homme du métier.  The exchanger 1 also comprises two other flanges forming two fastening lugs 10. These fastening lugs 10 make it possible to secure the exchanger 2 to a support (not shown in the appended figures), according to various fixing possibilities. known to those skilled in the art.
En se reportant cette fois aux figures 2 et 3 on voit que la bride d'entrée/sortie 9 présente un profil particulier 11. Ce profil 11 permet la réception, au niveau des flancs 12 de la bride 9, des bords longitudinaux 7, une fois ces derniers repliés.  Referring now to FIGS. 2 and 3, it can be seen that the inlet / outlet flange 9 has a particular profile 11. This profile 11 allows the reception, at the flanks 12 of the flange 9, of the longitudinal edges 7, a once these folded.
Plus précisément le profil 11 permet l'insertion de la bride d' entrée/sortie 9 entre les bords longitudinaux 7 lorsque ces derniers sont en position droite et le sertissage de la bride 9 par repliement desdits bords longitudinaux 7 sur les flancs 12.  More precisely, the profile 11 allows the insertion of the inlet / outlet flange 9 between the longitudinal edges 7 when the latter are in the upright position and the crimping of the flange 9 by folding said longitudinal edges 7 on the flanks 12.
Dans l'exemple de réalisation des figures annexées, le profil 11 comporte une gorge 13 pratiquée dans un flanc 12 de la bride 9 et sur son autre flanc 12 une excroissance 14. L'excroissance 14 possède une face inférieure 15 épousant sensiblement la forme du couvercle 4 et une face latérale 16 venant en butée contre l'intérieur de la paroi longitudinale 6 de la partie inférieure 3. De cette manière, lorsque les bords longitudinaux 7 sont repliés pour l'un dans la gorge 13 et pour l'autre sur l'excroissance 14 on obtient d'une part le sertissage de la bride 9 sur le couvercle 4 et d'autre part 1 ' enserrement du couvercle 4 entre la bride 9 et la partie inférieure 3. In the embodiment of the appended figures, the profile 11 comprises a groove 13 formed in a flank 12 of the flange 9 and on its other side 12 a protrusion 14. The protrusion 14 has a lower face 15 substantially matching the shape of the lid 4 and a side face 16 abutting the inside of the longitudinal wall 6 of the lower part 3. In this way, when the longitudinal edges 7 are folded for one in the groove 13 and for the other on the protrusion 14 is obtained on the one hand the crimping of the flange 9 on the cover 4 and on the other hand 1 'of the cover 4 between the flange 9 and the lower part 3.
Le sertissage de la bride 9 permet par conséquent de réaliser un maintien fiable du couvercle 4 entre la partie inférieure 3 et la bride 9 en une unique opération de sertissage.  The crimping of the flange 9 therefore makes it possible to securely hold the cover 4 between the lower part 3 and the flange 9 in a single crimping operation.
De manière avantageuse la gorge 13 et l'excroissance 14 s'étendent sur toute la longueur des flancs 12 de la bride 9.  Advantageously, the groove 13 and the protrusion 14 extend over the entire length of the flanks 12 of the flange 9.
De manière avantageuse, les pattes de fixation 10 sont également conçues pour être solidarisées avec le couvercle 4 et la partie inférieure 3 simultanément à l'opération de sertissage des brides 9.  Advantageously, the fixing lugs 10 are also designed to be secured to the lid 4 and the lower part 3 simultaneously with the crimping operation of the flanges 9.
Pour ce faire, et en se reportant principalement à la figure 4 on prévoit que le profil 17 des pattes de fixation 10 comporte, par exemple, deux extrémités 18 en forme de coins 19.  For this purpose, and referring mainly to FIG. 4, it is provided that the profile 17 of the fixing lugs 10 comprises, for example, two wedge-shaped ends 18.
Chaque coin 19 épouse la surface du couvercle 4 et s'insère jusque dans l'espace formé entre le couvercle 4 et les parois longitudinales 6 de la partie inférieure 3. La solidarisation entre les pattes de fixation 10, le couvercle 4 et la partie inférieure est obtenue lorsque les bords longitudinaux 7 sont repliés sur les coins 19 empêchant tout mouvement d'écartement des pattes 10 vis-à- vis du couvercle 4 et de la partie inférieure 3.  Each corner 19 matches the surface of the cover 4 and fits into the space formed between the cover 4 and the longitudinal walls 6 of the lower part 3. The fastening between the fixing lugs 10, the cover 4 and the lower part is obtained when the longitudinal edges 7 are folded over the corners 19 preventing any movement of spacing of the tabs 10 vis-à-vis the cover 4 and the lower part 3.
Il est important de signaler que, de manière avantageuse, les dimensions de la gorge 13 et de l'excroissance 14 sont calculées pour être compatibles avec un angle d' inclinaison déterminé entre la bride 9 et un plan de symétrie du collecteur 2. It is important to point out that, advantageously, the dimensions of the groove 13 and the protrusion 14 are calculated to be compatible with an angle of inclination determined between the flange 9 and a plane of symmetry of the collector 2.
Cette inclinaison est obtenue en jouant sur la longueur de l'excroissance 14 et sur la profondeur de la gorge 13. Il est ainsi possible d'obtenir de manière précise des inclinaisons différentes de la bride 9 par rapport au collecteur 2. On voit ainsi en se reportant à la figure 3 un exemple possible d' inclinaison entre la bride 9 et le collecteur 2, l'inclinaison étant contrôlée par les dimensions de la gorge 13 et de l'excroissance 14.  This inclination is obtained by varying the length of the protrusion 14 and the depth of the groove 13. It is thus possible to precisely obtain different inclinations of the flange 9 with respect to the collector 2. Referring to FIG. 3, a possible example of inclination between the flange 9 and the collector 2, the inclination being controlled by the dimensions of the groove 13 and the protrusion 14.
De la même manière, l'orientation de la patte de fixation 10 par rapport au collecteur 2 est contrôlée en jouant sur la longueur des coins 19. Dans l'exemple de réalisation des figures annexées et tel que particulièrement visible à la figure 4, les coins 19 sont sensiblement identiques, toutefois, pour obtenir d'autres inclinaisons, on pourra prévoir des coins 19 de longueurs non identiques.  In the same way, the orientation of the fixing lug 10 with respect to the collector 2 is controlled by varying the length of the corners 19. In the embodiment of the appended figures and as particularly visible in FIG. The corners 19 are substantially identical, however, to obtain other inclinations, may be provided corners 19 of non-identical lengths.
Comme illustré à la figure 5, l'échangeur conforme à l'invention peut également comprendre une bouteille 40, prévue en communication de fluide avec le collecteur. De façon connue de l'homme de l'art, une telle bouteille est orientée parallèlement au collecteur 2 et présente une paroi 42, définissant un volume intérieure 44. Une telle bouteille sert, notamment, à définir un volume de stockage de fluide et/ou à faciliter la séparation de phases, lorsque elle est associée à un condenseur. Ladite bouteille pourra aussi être équipée d'un filtre et/ou d'une cartouche de matériaux dessicants, non représentés.  As illustrated in FIG. 5, the exchanger according to the invention may also comprise a bottle 40, provided in fluid communication with the collector. In a manner known to those skilled in the art, such a bottle is oriented parallel to the collector 2 and has a wall 42, defining an inner volume 44. Such a bottle serves, in particular, to define a fluid storage volume and / or to facilitate phase separation, when associated with a condenser. Said bottle may also be equipped with a filter and / or a desiccant cartridge, not shown.
Ledit collecteur pourra alors être muni d'une bride, telle qu'évoquée plus haut, définissant cette fois une bride 30 d'accrochage de la bouteille 40, ladite bride d'accrochage 30 étant éventuellement prévue en continuité de matière de la bouteille 40. Dans l'exemple représenté, la bride de fixation 30 est du type à excroissances 14 ou coins 19. Said collector may then be provided with a flange, as mentioned above, this time defining a flange 30 for attaching the bottle 40, said attachment flange 30 possibly being provided in continuity of material of the bottle 40. In the example shown, the fastening flange 30 is of the excrescence type 14 or corners 19.
Il est également important de souligner que pour positionner le couvercle 4 dans la partie inférieure 3 lors du repliement des bords longitudinaux, on prévoit au niveau des parois longitudinales 6 et/ou des parois transversales 8 une déformation locale ou une surépaisseur. Cette déformation local ou surépaisseur constituant une butée d'arrêt 20 empêchant le couvercle 4 de s'enfoncer dans le fond de la partie inférieure 3 en forçant sur les parois longitudinales 6.  It is also important to emphasize that to position the cover 4 in the lower part 3 during the folding of the longitudinal edges is provided at the longitudinal walls 6 and / or transverse walls 8 local deformation or extra thickness. This local deformation or thickening constituting a stop 20 preventing the cover 4 from sinking into the bottom of the lower part 3 by forcing on the longitudinal walls 6.
Cela étant, il est à noter que, de façon connue, le collecteur 2 pourra comprendre des cloisons divisant son volume interne en plusieurs parties, reliées chacune à un nombre donné de tubes de l'échangeur, définissant des passes de circulation de fluide, avec pour effet de permettre une circulation alternée du fluide dans une direction alternée d'une passe à l'autre.  However, it should be noted that, in known manner, the collector 2 may comprise partitions dividing its internal volume into several parts, each connected to a given number of tubes of the exchanger, defining fluid circulation passes, with to effect an alternating circulation of the fluid in an alternating direction from one pass to another.
Dans un tel cas et selon une variante de réalisation, non représentée, le couvercle 4 pourra prendre appui sur la partie inférieure 3 par l'intermédiaire desdites cloisons et/ou des parois transversales 8 de façon alternative et/ou complémentaire à un appui réalisé par les butées d'arrêt 20.  In such a case and according to an alternative embodiment, not shown, the cover 4 can bear on the lower part 3 by means of said partitions and / or transverse walls 8 alternatively and / or complementary to a support made by the stops 20.
On voit ainsi que la structure proposée permet de réaliser simultanément le sertissage des différents type de brides 9, 10, 30 prévues le collecteur 2, tout en assurant le maintien du couvercle 4.  It can thus be seen that the proposed structure makes it possible simultaneously to crimp the various types of flanges 9, 10, 30 provided for the collector 2, while ensuring the maintenance of the cover 4.
Plus précisément, les bords repliés 7 seront présents, par exemple, au niveau desdites brides, tout au moins au niveau de l'une au moins desdites brides, et c'est le sertissage de la ou desdites brides par les bords repliés 7 qui bloquera le couvercle 4 sur la partie inférieure 3. Il pourra aussi être prévu des bords repliés 7 au-delà desdites brides pour assurer un blocage en position du couvercle non seulement par les brides mais également par les parties pliées, alors en contact direct avec ledit couvercle, prévues au-delà des brides. More precisely, the folded edges 7 will be present, for example, at the level of said flanges, at least at the level of at least one of said flanges, and it is the crimping of said flange (s) by the folded edges 7 which will block the lid 4 on the lower part 3. It can also be provided folded edges 7 beyond said flanges to ensure a locking position of the lid not only by the flanges but also by the folded parts, then in direct contact with said cover, provided beyond the flanges.
Le procédé d'assemblage de l'échangeur consiste à réaliser une première étape de positionnement du couvercle 4 du collecteur 2. Pour ce faire le couvercle 4 est inséré dans la partie inférieure 3 jusqu'à la butée d'arrêt 20. Ensuite les différentes brides d' entrée/sortie 9 sont positionnées sur le couvercle 4. Ce positionnement de la bride 9 est aisé puisqu' il suffit de déplacer verticalement les brides 9 jusqu'au contact avec le couvercle 4 en faisant coïncider les ouvertures prévues sur le couvercle 4 avec celles prévues sur les brides 9.  The method of assembling the exchanger consists in carrying out a first step of positioning the cover 4 of the collector 2. To do this, the cover 4 is inserted in the lower part 3 as far as the stop 20. inlet / outlet flanges 9 are positioned on the cover 4. This positioning of the flange 9 is easy since it suffices to move the flanges 9 vertically up to the contact with the cover 4 by making the openings provided on the cover 4 coincide. with those provided on the flanges 9.
Dans le mode de réalisation illustré l'échangeur 1 comporte des pattes de fixation 10 au niveau du collecteur 2, on procède par conséquent également au positionnement des pattes de fixation 10. Toutefois cette étape est naturellement supprimée lorsque les pattes de fixation 10 ne sont pas disposées sur le couvercle du collecteur 2 ou encore dans un mode de réalisation dégradé de l'invention dans lequel les pattes de fixation 10 sont fixées de manière classique sur le couvercle 4 notamment par soudure ou agrafage.  In the embodiment illustrated, the heat exchanger 1 has fastening lugs 10 at the collector 2, the positioning of the fastening lugs 10 is consequently also carried out. However, this step is naturally omitted when the fastening lugs 10 are not removed. disposed on the cover of the collector 2 or in a degraded embodiment of the invention wherein the fastening lugs 10 are fixed in a conventional manner on the lid 4 in particular by welding or stapling.
Le procédé d'assemblage de l'échangeur 1 consiste ensuite à réaliser une étape de repliement des bords longitudinaux 7. Cette étape de repliement permet de positionner l'extrémité des bords longitudinaux 7 dans les gorges 13 et sur les excroissances 14 des brides 9 ainsi que, le cas échéant, sur les coins 19.  The method of assembly of the exchanger 1 then consists in carrying out a step of folding the longitudinal edges 7. This folding step makes it possible to position the end of the longitudinal edges 7 in the grooves 13 and on the protuberances 14 of the flanges 9 and as appropriate, on the corners 19.
Lorsque les bords longitudinaux 7 sont placés sur les flancs 12 des brides 9 et recouvrent les coins 19 des pattes de fixation 10, le sertissage des brides 9 et des pattes 10 est réalisé et le couvercle 4 du collecteur 2 est enserré. L'assemblage des différents composants 3,4, 9 et 10 est par conséquent réalisé simultanément en une seule opération de sertissage. D'autres caractéristiques de l'invention auraient également pu être envisagées sans pour autant sortir du cadre de l'invention définie par les revendications ci- après . When the longitudinal edges 7 are placed on the flanks 12 of the flanges 9 and cover the corners 19 of the attachment lugs 10, the crimping of the flanges 9 and lugs 10 is performed and the cover 4 of the collector 2 is clamped. The assembly of the various components 3, 4, 9 and 10 is therefore performed simultaneously in a single crimping operation. Other features of the invention could also have been envisaged without departing from the scope of the invention defined by the claims below.
Notamment, à titre d'exemple, dans d'autres modes de réalisation le profil 11 des brides 9 pourra être différent et par exemple chaque flanc 12 pourra comprendre une excroissance 14 pour réaliser le sertissage ou encore chaque flanc 12 pourra comprendre une gorge 13 apte à recevoir l'extrémité repliée du bord longitudinal 7.  In particular, by way of example, in other embodiments, the profile 11 of the flanges 9 may be different and for example each flank 12 may comprise an excrescence 14 for making the crimping or else each flank 12 may comprise a groove 13 capable of receiving the folded end of the longitudinal edge 7.
Dans un autre mode de réalisation, les gorges 13 et les excroissances 14 des brides 9 et/ou les coins 19 des pattes 10 ne s'étendent que partiellement sur la longueur des composants 9 et 10.  In another embodiment, the grooves 13 and the protuberances 14 of the flanges 9 and / or the corners 19 of the tabs 10 extend only partially along the length of the components 9 and 10.
Au lieu d'être rectilignes, les bords longitudinaux Instead of being rectilinear, the longitudinal edges
7 pourront se présenter sous la forme de pattes de sertissage distribuées le long des flancs, par exemple régulièrement et/ou de manière à coïncider avec les emplacements des gorges, des excroissances et/ou des coins des brides, l'assemblage étant réalisé après repliement desdites pattes de sertissage. 7 may be in the form of crimping tabs distributed along the sidewalls, for example regularly and / or so as to coincide with the locations of the grooves, protrusions and / or the corners of the flanges, the assembly being performed after folding said crimping tabs.
