Description

L'invention concerne un dispositif pour l'assemblage d'au moins un équipement, tel qu'un échangeur de chaleur secondaire, sur un échangeur de chaleur primaire, notamment de véhicule automobile.The invention relates to a device for assembling at least minus equipment, such as a secondary heat exchanger, on a primary heat exchanger, in particular of motor vehicle.

Plus particulièrement, elle concerne un tel dispositif susceptible d'être utilisé lorsque ledit échangeur de chaleur primaire comporte un collecteur de tubes et une boíte collectrice sertie sur le collecteur de tubes, la périphérie dudit collecteur de tubes formant une gorge de réception d'un joint d'étanchéité entre le collecteur de tubes et la boíte collectrice.More particularly, it relates to such a device capable of being used when said heat exchanger primary includes a tube collector and a box collector set on the tube collector, the periphery of said tube collector forming a groove for receiving a gasket between the tube collector and the box collecting.

Il est connu d'assembler sur un échangeur de chaleur, tel qu'un radiateur de refroidissement d'un moteur de véhicule automobile, un ou plusieurs équipements afin de constituer un ensemble, appelé encore module, prêt à être installé dans le véhicule. L'un de ces équipements peut être, par exemple, un échangeur de chaleur secondaire, en particulier un refroidisseur d'air de suralimentation du moteur, un condenseur de climatisation ou un radiateur d'huile. Un autre équipement peut être, par exemple, une buse de ventilateur.It is known to assemble on a heat exchanger, such than a vehicle engine cooling radiator automobile, one or more pieces of equipment in order to constitute a assembly, also called module, ready to be installed in the vehicle. One of these devices can be, for example, a secondary heat exchanger, in particular a cooler engine charge air, a condenser air conditioning or an oil cooler. Another equipment can be, for example, a fan nozzle.

L'assemblage de ces équipements sur l'échangeur est obtenu généralement par l'intermédiaire de pattes solidaires de l'équipement et de vis introduites dans les boítes collectrices de l'échangeur principal. On a également proposé dans le cas de deux échangeurs de chaleur, des systèmes d'assemblage par emboítement ou encliquetage des ensembles collecteurs.The assembly of this equipment on the exchanger is obtained generally by means of legs integral with the equipment and screws introduced into the manifolds of the main exchanger. We also proposed in the case of two heat exchangers, assembly systems by fitting or snapping on the manifold assemblies.

Ces assemblages connus présentent l'inconvénient de nécessiter des opérations coûteuses en temps et en outillage.These known assemblies have the drawback of requiring costly operations in terms of time and tools.

L'invention vise notamment à pallier cet inconvénient. The invention aims in particular to overcome this drawback.

Plus particulièrement, l'invention a pour but de fournir un module d'échange de chaleur dont la réalisation, et notamment les opérations de montage, soit le plus simple possible.More particularly, the invention aims to provide a heat exchange module, the production of which, and in particular assembly operations, as simple as possible.

A cet effet, l'invention a tout d'abord pour objet un dispositif pour l'assemblage d'au moins un équipement, tel qu'un échangeur de chaleur secondaire, sur un échangeur de chaleur primaire, notamment de véhicule automobile, ledit échangeur de chaleur primaire comportant un collecteur de tubes et une boíte collectrice sertie sur le collecteur de tubes, la périphérie dudit collecteur de tubes formant une gorge de réception d'un joint d'étanchéité entre le collecteur de tubes et la boíte collectrice, le dispositif comprenant d'une part des premiers moyens d'encliquetage sur l'extérieur de ladite gorge, et d'autre part des moyens de réception et de blocage dudit équipement.To this end, the invention firstly relates to a device for assembling at least one piece of equipment, such as that a secondary heat exchanger, on a heat exchanger primary heat, in particular of a motor vehicle, said primary heat exchanger comprising a collector of tubes and a manifold set on the manifold tubes, the periphery of said tube collector forming a groove for receiving a seal between the manifold of tubes and the manifold, the device comprising on the one hand, the first snap-on means the outside of said groove, and on the other hand means of receiving and blocking said equipment.

Le montage de l'équipement sur l'échangeur de chaleur peut donc se limiter à de simples opérations d'encliquetage. Il en résulte une simplification du montage du module d'échange de chaleur.The mounting of the equipment on the heat exchanger can therefore be limited to simple latching operations. It results in a simplification of the assembly of the exchange module of heat.

Le sertissage de la boíte collectrice sur le collecteur de tubes s'effectue couramment à l'aide de dents faisant saillie du bord de la gorge, rabattues sur un épaulement de la boíte collectrice. Dans ce cas, lesdits premiers moyens d'encliquetage peuvent comprendre un ensemble de pattes agencées pour prendre appui sur la surface extérieure de la gorge, et au moins une butée agencée pour s'encliqueter sur le bord de la gorge, entre les dents en saillie.The crimping of the manifold on the manifold tubes are commonly done using protruding teeth from the edge of the throat, folded over a shoulder of the box collecting. In this case, said first latching means may include a set of legs arranged to lean on the outer surface of the throat, and minus a stopper arranged to snap onto the edge of the throat, between protruding teeth.

Dans un premier mode de réalisation particulier, lesdits moyens de réception et de blocage comprennent des deuxièmes moyens d'encliquetage complémentaires d'un élément dudit équipement.In a first particular embodiment, said receiving and blocking means comprise second complementary latching means of an element of said equipment.

Dans ce cas, et lorsque l'équipement à assembler est un échangeur de chaleur secondaire, lesdits deuxièmes moyens d'encliquetage peuvent être complémentaires d'une boíte collectrice dudit échangeur de chaleur secondaire.In this case, and when the equipment to be assembled is a secondary heat exchanger, said second means can be complementary to a box collector of said secondary heat exchanger.

Dans un deuxième mode de réalisation particulier, lesdits moyens de réception et de blocage comprennent une partie en saillie comportant des découpes de réception des tubes de circulation de fluide de l'échangeur de chaleur secondaire.In a second particular embodiment, said receiving and blocking means comprise a part in projection comprising cutouts for receiving the tubes of fluid circulation of the secondary heat exchanger.

Dans ce cas, lesdits moyens de réception et de blocage peuvent comprendre un crochet de blocage encliquetable sur une joue dudit échangeur de chaleur secondaire.In this case, said receiving and blocking means may include a locking hook that can be snapped onto one cheek of said secondary heat exchanger.

L'invention a également pour objet un module d'échange de chaleur, notamment de véhicule automobile, comprenant un échangeur de chaleur primaire et au moins un équipement, tel qu'un échangeur de chaleur secondaire, dans lequel ledit équipement est assemblé audit échangeur de chaleur primaire à l'aide d'au moins un dispositif tel que décrit ci-dessus.The invention also relates to a module for exchanging heat, in particular for a motor vehicle, comprising a primary heat exchanger and at least one equipment, such than a secondary heat exchanger, in which said equipment is assembled to said primary heat exchanger using at least one device as described above.

On décrira maintenant, à titre d'exemple non limitatif, deux modes de réalisation particuliers de l'invention, en référence aux dessins schématiques annexés dans lesquels :

  • la figure 1 est une vue partielle en coupe d'un premier mode de réalisation de l'invention ;
  • la figure 2 est une vue à plus grande échelle du détail II de la figure 1 ;
  • la figure 3 est une vue partielle en perspective arrachée de ce premier mode de réalisation ;
  • les figures 4 et 5 sont des vues partielles en perspective du dispositif d'assemblage utilisé ;
  • la figure 6 est une vue partielle en perspective d'un deuxième mode de réalisation de l'invention ;
  • la figure 7 est une vue partielle en perspective du dispositif d'assemblage utilisé dans ce deuxième mode de réalisation ; et
  • les figures 8 et 9 sont des vues en perspective de ce deuxième mode de réalisation avant montage de l'échangeur de chaleur secondaire.
There will now be described, by way of nonlimiting example, two particular embodiments of the invention, with reference to the appended schematic drawings in which:
  • Figure 1 is a partial sectional view of a first embodiment of the invention;
  • Figure 2 is an enlarged view of detail II of Figure 1;
  • Figure 3 is a partial perspective view cut away from this first embodiment;
  • Figures 4 and 5 are partial perspective views of the assembly device used;
  • Figure 6 is a partial perspective view of a second embodiment of the invention;
  • Figure 7 is a partial perspective view of the assembly device used in this second embodiment; and
  • Figures 8 and 9 are perspective views of this second embodiment before mounting of the secondary heat exchanger.

On voit à la figure 1 un échangeur de chaleur primaire 1 avec son faisceau de tubes 2 et un de ses ensembles collecteurs 3, ainsi qu'un échangeur de chaleur secondaire 4 avec son faisceau de tubes 5 et un de ses ensembles collecteurs 6. Les deux échangeurs de chaleur sont assemblés au moyen d'un dispositif d'assemblage 7 du côté représenté, et de toute manière convenable, éventuellement par un dispositif du même type, du côté non représenté.We see in Figure 1 a primary heat exchanger 1 with its bundle of tubes 2 and one of its manifold assemblies 3, as well as a secondary heat exchanger 4 with its tube bundle 5 and one of its manifold assemblies 6. The two heat exchangers are assembled by means of a assembly device 7 on the side shown, and any in a suitable manner, possibly by a device of the same type, on the side not shown.

L'ensemble collecteur 3 est composé pour l'essentiel d'un collecteur de tubes 8 qui reçoit les extrémités des tubes du faisceau 2, et d'une boíte collectrice 9 sertie sur le collecteur de tubes 8.The manifold assembly 3 is essentially composed of a tube collector 8 which receives the ends of the tubes of the bundle 2, and a manifold 9 set on the tube collector 8.

L'ensemble collecteur 6 est sensiblement cylindrique et composé pour l'essentiel de deux profilés en U dont l'un 10 reçoit les extrémités des tubes du faisceau 5 et l'autre 11 est brasé sur le premier.The manifold assembly 6 is substantially cylindrical and composed essentially of two U-shaped profiles, one of which 10 receives the ends of the bundle tubes 5 and the other 11 is soldered on the first.

Les bords du collecteur de tubes 8 forment une gorge 12 dans laquelle est disposé un joint d'étanchéité 13. Les bords de la boíte collectrice 9 forment un bourrelet 14 engagé dans la gorge 12 et en appui sur le joint 13.The edges of the tube collector 8 form a groove 12 in which is arranged a seal 13. The edges of the manifold 9 form a bead 14 engaged in the groove 12 and resting on seal 13.

Le sertissage de la boíte collectrice 9 sur le collecteur de tubes 8 est effectué par un ensemble de dents 15 en saillie du bord 16 de la gorge 12. Les dents 15 sont recourbées et mises en appui sur un épaulement 17 de la boíte collectrice 9. The crimping of the manifold 9 on the collector of tubes 8 is made by a set of projecting teeth 15 from the edge 16 of the groove 12. The teeth 15 are curved and supported on a shoulder 17 of the manifold 9.

Le dispositif d'assemblage 7 est réalisé en matière plastique relativement élastique pour permettre les encliquetages. Il comprend un corps allongé 18 le long duquel font saillie en alternance un premier ensemble de pattes 19 du côté de son montage sur l'échangeur de chaleur 1, et un deuxième ensemble de pattes 20 du côté de l'assemblage de l'échangeur 4. Les pattes 19 comportent à leur extrémité un bec recourbé 21 et les pattes 20 supportent ensemble à leur extrémité un profil continu 22 généralement plan. Le profil 22 est dirigé vers l'extérieur de la concavité des pattes 20.The assembly device 7 is made of plastic relatively elastic to allow snaps. he comprises an elongated body 18 along which protrude in alternating a first set of legs 19 on the side of its mounting on the heat exchanger 1, and a second set of lugs 20 on the assembly side of the exchanger 4. The legs 19 have at their end a curved spout 21 and the legs 20 together support at their end a profile continuous 22 generally planar. Profile 22 is directed to outside of the concavity of the legs 20.

La section transversale du côté concave des pattes 19 et des becs 21 correspond à la section transversale extérieure de la gorge 12, et la section transversale du côté concave des pattes 20 correspond à la section transversale extérieure de l'ensemble collecteur 6. Les concavités des pattes 19 et 20 sont dirigées en sens inverse.The cross section of the concave side of the legs 19 and spouts 21 corresponds to the external cross section of the groove 12, and the cross section of the concave side of the legs 20 corresponds to the outer cross section of the manifold assembly 6. The concavities of the legs 19 and 20 are directed in reverse.

Chaque patte 20 supporte par ailleurs de son côté convexe une butée 23, l'ensemble des butées 23 faisant face à l'ensemble des becs 21. La distance des butées 23 aux pattes 19 est sensiblement égale à la profondeur extérieure de la gorge 12.Each tab 20 also supports on its convex side a stop 23, the set of stops 23 facing the assembly spouts 21. The distance from the stops 23 to the legs 19 is substantially equal to the external depth of the groove 12.

L'assemblage des deux échangeurs s'effectue en encliquetant en premier lieu le dispositif d'assemblage 7 sur la gorge 12 de l'échangeur 1. Les pattes 20 et les becs 21 viennent ainsi entourer la gorge 12, tandis que les butées 23 viennent en appui sur le bord 16 de la gorge 12, entre les dents 15. Les pattes 20 et le profil 22 font alors saillie du côté opposé à l'échangeur 1.The two exchangers are assembled by snap-fastening firstly the assembly device 7 on the groove 12 of the exchanger 1. The legs 20 and the spouts 21 thus come surround the groove 12, while the stops 23 come in press on the edge 16 of the groove 12, between the teeth 15. The tabs 20 and profile 22 then protrude from the opposite side at exchanger 1.

L'échangeur 4 est alors encliqueté sur les pattes 20. Cet encliquetage est favorisé par le profil 22 qui provoque l'écartement des pattes 20 lors de l'appui de l'ensemble collecteur 6. Une fois l'encliquetage réalisé, les pattes 20 maintiennent l'échangeur 4 en enserrant l'ensemble collecteur 6. The exchanger 4 is then snapped onto the lugs 20. This snap is favored by the profile 22 which causes the spacing of the legs 20 when the assembly is pressed collector 6. Once the snap-in has been made, the lugs 20 maintain the exchanger 4 by enclosing the manifold assembly 6.

On décrira maintenant le mode de réalisation des figures 6 à 9 dans lesquelles les mêmes références que dans les figures 1 à 5 ont été utilisées pour désigner les éléments homologues.We will now describe the embodiment of Figures 6 to 9 in which the same references as in the figures 1 to 5 were used to designate the homologous elements.

On voit à la figure 6 l'échangeur primaire 1 assemblé à l'échangeur secondaire 4 au moyen d'un dispositif d'assemblage 7'.FIG. 6 shows the primary exchanger 1 assembled at the secondary exchanger 4 by means of an assembly device 7 '.

Le dispositif 7', représenté en détail à la figure 7, est réalisé en matière plastique relativement élastique et comporte un corps, constitué d'une plaque plane allongée 24, et un ensemble d'organes de fixation réalisés d'une seule pièce avec le corps.The device 7 ′, shown in detail in FIG. 7, is made of relatively elastic plastic and comprises a body, consisting of an elongated flat plate 24, and a set of fixing members made from a single piece with the body.

Un des grands côtés de la plaque 24 forme à chacune de ses extrémités un crochet d'encliquetage 25 de forme complémentaire de celle des joues 26 de l'échangeur 4 pour s'encliqueter chacun sur une de ces joues. Entre les deux crochets 26 est formé un ensemble de paires de dents 27 et 28.One of the long sides of the plate 24 forms each of its ends a snap hook 25 of complementary shape that of the cheeks 26 of the exchanger 4 to snap each on one of these cheeks. Between the two hooks 26 a set of pairs of teeth 27 and 28 is formed.

Chaque paire de dents 27, 28 délimite un espace 29 susceptible de recevoir un des tubes 30 de l'échangeur 4, et les paires de dents sont espacées d'une distance égale au pas des tubes 30. Chaque dent d'une paire de dents porte, en vis-à-vis de l'autre dent de la même paire, des ondulations 31 permettant le maintien d'un tube 30.Each pair of teeth 27, 28 delimits a space 29 capable of to receive one of the tubes 30 of the exchanger 4, and the pairs of teeth are spaced a distance equal to the pitch of the tubes 30. Each tooth of a pair of teeth carries, facing on the other tooth of the same pair, undulations 31 allowing the maintenance of a tube 30.

Sur chacune de ses faces, et du côté opposé aux dents 28, 29, la plaque 24 porte un ensemble de pattes 19' munies de becs 21', et un ensemble de butées 23', ces deux ensembles étant alternés et se faisant face. En fait, les pattes 19', les becs 21' et les butées 23' ont une même conformation et une même disposition relative que les pattes 19, les becs 21 et les butées 23 du premier mode de réalisation, de façon à pouvoir s'encliqueter sur la gorge 12 de l'échangeur 1.On each of its faces, and on the side opposite the teeth 28, 29, the plate 24 carries a set of legs 19 'provided with spouts 21 ', and a set of stops 23', these two sets being alternating and facing each other. In fact, the 19 'legs, the spouts 21 'and the stops 23' have the same conformation and a same relative arrangement as the legs 19, the beaks 21 and the stops 23 of the first embodiment, so that ability to snap onto groove 12 of exchanger 1.

L'assemblage des échangeurs 1 et 4 s'effectue dans le cas présent de la manière suivante. The assembly of exchangers 1 and 4 is carried out in the case present as follows.

Le dispositif 7' est tout d'abord encliqueté sur la gorge 12 comme dans le premier mode de réalisation. On observera que le dispositif 7' est sensiblement symétrique par rapport au plan de la plaque 24 de manière à pouvoir être monté indifféremment dans un sens ou dans l'autre, à l'une ou l'autre extrémité de l'échangeur 1.The device 7 'is first snapped onto the groove 12 as in the first embodiment. We will observe that the device 7 'is substantially symmetrical with respect to the plane of the plate 24 so that it can be mounted indifferently one way or the other, to one or the other end of the exchanger 1.

L'échangeur 4 est ensuite monté sur le dispositif d'assemblage 7'. A cet effet, les tubes 30 de l'échangeur 4 sont insérés dans les espaces 29 et, simultanément, les crochets 25 sont encliquetés sur les joues 26 de l'échangeur 4.The exchanger 4 is then mounted on the assembly device 7 '. To this end, the tubes 30 of the exchanger 4 are inserted in spaces 29 and, simultaneously, the hooks 25 are snapped onto the cheeks 26 of the exchanger 4.

L'invention permet ainsi d'assembler par simple encliquetage l'échangeur 4, ou tout autre équipement, à l'échangeur 1.The invention thus makes it possible to assemble by simple snap-fastening exchanger 4, or any other equipment, at exchanger 1.

L'assemblage se fera de préférence à l'aide de quatre dispositifs montés deux par deux sur des côtés opposés du collecteur de l'échangeur primaire. Toutefois il est possible de réaliser l'assemblage avec deux dispositifs montés respectivement sur ces deux côtés opposés.The assembly will preferably be done using four devices mounted two by two on opposite sides of the collector of the primary exchanger. However it is possible to carry out the assembly with two mounted devices respectively on these two opposite sides.

Le dispositif est de préférence distinct de l'équipement. Cependant il est envisageable, dans certains cas, de réaliser le dispositif d'une seule pièce avec l'équipement, par exemple par moulage d'une matière plastique.The device is preferably separate from the equipment. However it is possible, in some cases, to carry out the one-piece device with the equipment, for example by molding a plastic material.

On a décrit l'assemblage d'un équipement sur une face de l'échangeur primaire mais, bien entendu, deux équipements pourraient être assemblés de la même manière chacun sur une face de l'échangeur primaire.We have described the assembly of equipment on one face of the primary exchanger but, of course, two pieces of equipment could be assembled in the same way each on a face of the primary exchanger.
