ECHANGEUR DE CHALEUR COMPRENANT AU MOINS UN ENSEMBLE D'UN FAISCEAU D'ECHANGE DE CHALEUR, DE DEUX COLLECTEURS ET D'UN CARTER ADAPTE POUR RECEVOIR EN SON SEIN LEDIT ENSEMBLE Domaine de l'invention  HEAT EXCHANGER COMPRISING AT LEAST ONE HEAT EXCHANGE BEAM ASSEMBLY, TWO COLLECTORS AND A HOUSING ADAPTED TO RECEIVE IN ITS BRIEF THEREWITH FIELD OF THE INVENTION
La présente invention concerne un échangeur de chaleur, destiné notamment à un véhicule automobile. Plus précisément, l'invention concerne un échangeur de chaleur pourvu d'un carter comprenant une paroi spécifique ainsi qu'un procédé permettant d'obtenir ledit échangeur de chaleur selon l'invention. The present invention relates to a heat exchanger, intended in particular for a motor vehicle. More specifically, the invention relates to a heat exchanger provided with a casing comprising a specific wall and a method for obtaining said heat exchanger according to the invention.
Etat de la technique State of the art
De nos jours, les moteurs à combustion des véhicules automobiles sont fréquemment alimentés en air comprimé afin d'améliorer les performances desdits moteurs. Cet air comprimé est souvent désigné à l'aide du terme « air de suralimentation ». L'air comprimé est obtenu en utilisant un compresseur entraîné par les gaz d'échappement, par exemple. La compression de l'air a pour effet d'échauffer l'air comprimé. Il s'avère nécessaire de refroidir l'air comprimé avant son introduction à l'intérieur de la chambre à combustion du moteur afin de réduire la température dudit air comprimé avant son introduction dans le cylindre. Nowadays, combustion engines of motor vehicles are frequently supplied with compressed air to improve the performance of said engines. This compressed air is often referred to as "boost air". Compressed air is obtained using a compressor driven by the exhaust gas, for example. The compression of the air has the effect of heating the compressed air. It is necessary to cool the compressed air before its introduction into the combustion chamber of the engine to reduce the temperature of said compressed air before its introduction into the cylinder.
Afin de refroidir l'air comprimé, il est connu d'utiliser un échangeur de chaleur comprenant un faisceau d'échange de chaleur constitué d'un l'ensemble de plaques. Les différentes plaques sont positionnées les unes sur les autres et forment, en combinaison, un conduit permettant de guider un premier fluide, tel qu'un liquide, d'une entrée vers une sortie, dans lequel ce liquide est adapté pour refroidir de l'air guidé à l'intérieur d'un deuxième conduit obtenu à l'aide de l'assemblage des plaques. In order to cool the compressed air, it is known to use a heat exchanger comprising a heat exchange bundle consisting of a set of plates. The various plates are positioned one on the other and form, in combination, a conduit for guiding a first fluid, such as a liquid, from an inlet to an outlet, in which the liquid is adapted to cool with water. guided air inside a second duct obtained by means of the assembly of the plates.
Le faisceau d'échange de chaleur, décrit ci-dessus, est positionné à l'intérieur d'un carter ou boîtier. L'obtention d'un échangeur de chaleur est conditionnée par la présence de différents autres composants. Ainsi, un échangeur de chaleur comprend, notamment, au moins un premier et un deuxième collecteurs, lesdits collecteurs étant positionnés aux extrémités opposées du faisceau d'échange de chaleur. En règle générale, les différents composants de l'échangeur de chaleur comprennent du métal. Cela permet la fixation desdits différents composants les uns sur les autres à l'aide d'un processus de brasage, dans un four adapté. The heat exchange bundle, described above, is positioned inside a housing or housing. The obtaining of a heat exchanger is conditioned by the presence of different other components. Thus, a heat exchanger comprises, in particular, at least a first and a second collector, said collectors being positioned at the opposite ends of the heat exchange bundle. In general, the various components of the heat exchanger comprise metal. This allows the fixing of said different components on each other by means of a brazing process, in a suitable oven.
Cependant, au cours du procédé de brasage, lors de la production d'un échangeur de chaleur, les différents composants, situés à l'intérieur du carter, sont soumis à la chaleur diffusée par le four. L'effet de la chaleur sur les différents composants provoque une dilatation desdits composants. Cependant, la dilatation des composants n'est pas identique à la dilatation de la paroi formant le carter. Cette différence engendre un assemblage incorrect des différents composants. En effet, les collecteurs situés à chaque extrémité du faisceau d'échange sont positionnés de manière incorrecte à l'issue du procédé de brasage. However, during the brazing process, during the production of a heat exchanger, the various components, located inside the housing, are subjected to the heat diffused by the oven. The effect of the heat on the various components causes a dilation of said components. However, the expansion of the components is not identical to the expansion of the wall forming the housing. This difference results in incorrect assembly of the different components. Indeed, the collectors located at each end of the exchange bundle are incorrectly positioned at the end of the brazing process.
Objet de l'invention Object of the invention
L'échangeur de chaleur selon la présente invention vise à remédier aux inconvénients des échangeurs de chaleur, tels que divulgués au sein de l'état de la technique, en permettant un assemblage d'un faisceau d'échange de chaleur présent à l'intérieur du carter avant l'assemblage final à l'aide d'un procédé de brasage. The heat exchanger according to the present invention aims to overcome the disadvantages of heat exchangers, as disclosed in the state of the art, by allowing an assembly of a heat exchange bundle present inside. of the housing before final assembly using a brazing process.
A cet effet, la présente invention concerne un échangeur de chaleur adapté pour un échange de chaleur entre un premier et un deuxième fluide, destiné notamment à un véhicule automobile, comprenant au moins un carter permettant de recevoir respectivement en son sein, un premier collecteur, un faisceau d'échange et un deuxième collecteur, dans une direction longitudinale dudit échangeur de chaleur, dans lequel le carter est pourvu d'au moins un premier verrou et un deuxième verrou, le premier verrou étant adapté pour limiter le déplacement dudit premier collecteur, selon la direction longitudinale de l'échangeur de chaleur, le deuxième verrou étant adapté pour limiter le déplacement du deuxième collecteur dans la direction longitudinale de l'échangeur de chaleur. For this purpose, the present invention relates to a heat exchanger adapted for a heat exchange between a first and a second fluid, intended in particular for a motor vehicle, comprising at least one casing for receiving respectively within it, a first collector, an exchange beam and a second collector, in a longitudinal direction of said heat exchanger, wherein the housing is provided with at least a first latch and a second latch, the first latch being adapted to limit the displacement of said first collector, in the longitudinal direction of the heat exchanger, the second latch being adapted to limit the displacement of the second collector in the longitudinal direction of the heat exchanger.
La présence d'au moins un premier et un deuxième verrou, chacun d'entre eux, étant adapté pour limiter le mouvement d'un collecteur dans le sens longitudinal du carter, permet d'éviter que les collecteurs ne soient poussés vers l'extérieur dudit carter sous l'influence de la dilatation du faisceau d'échange de chaleur, lors du processus de brasage. En d'autres termes, les éléments présents à l'intérieur du carter conservent leur position respective malgré la différence de dilatation, de même que le carter lui-même. Cela permet une connexion correcte des différents composants pendant le processus de brasage. The presence of at least a first and a second latch, each of them being adapted to limit the movement of a collector in the longitudinal direction of the casing, prevents the collectors from being pushed outwards. said casing under the influence of the expansion of the heat exchange bundle during the brazing process. In other words, the elements present inside the housing retain their respective position despite the difference in expansion, as well as the housing itself. This allows a proper connection of the different components during the soldering process.

Selon un mode de réalisation de l'invention, les au moins premier et deuxième verrou comprennent une portion de la paroi du carter, s'étendant dans une direction transversale de l'échangeur de chaleur, dans lequel ladite portion de la paroi comprend au moins une fente. Selon un mode de réalisation de l'invention, la portion de la paroi du carter, pour former les au moins premier et deuxième verrou, est positionnée entre le rebord de la paroi du carter et la fente.

According to one embodiment of the invention, the at least first and second latches comprise a portion of the housing wall, extending in a transverse direction of the heat exchanger, wherein said portion of the wall comprises at least a slit. According to one embodiment of the invention, the portion of the housing wall, to form the at least first and second latch, is positioned between the rim of the housing wall and the slot.
Selon un mode de réalisation de l'invention, les au moins premier et deuxième verrou se déplacent de la première position vers la deuxième position, sous l'influence d'une déformation plastique du matériau de la paroi du carter. Selon un deuxième aspect de la présente invention, l'invention concerne une paroi adaptée afin de former le carter pour l'échangeur de chaleur.

Comme montré sur la figure 1, le carter comprend un ensemble d'éléments comprenant une première paroi 3 et une deuxième paroi 4, fixées l'une à l'autre pour, après fixation, envelopper le faisceau d'échange 2. A chacune de ses extrémités, le faisceau d'échange 2 est pourvu de collecteurs 5, 6. L'échangeur de chaleur 1 est par ailleurs pourvu d'un premier élément d'entrée 7 et d'un premier élément de sortie 8, destinés à un premier fluide. Un deuxième élément d'entrée 9 et un deuxième élément de sortie 10, destinés à un deuxième fluide, sont fixés sur l'élément 4 afin de former le carter. FIG. 1 shows, schematically, a heat exchanger 1. The heat exchanger 1 comprises an exchange beam 2 adapted for a heat exchange between a first and a second fluid. The exchange beam 2 is enveloped by a housing. As shown in FIG. 1, the casing comprises a set of elements comprising a first wall 3 and a second wall 4, fixed to each other so that, after fixing, the exchange beam 2 is wrapped. its ends, the exchange beam 2 is provided with collectors 5, 6. The heat exchanger 1 is furthermore provided with a first input element 7 and a first output element 8, intended for a first fluid. A second input element 9 and a second output element 10, for a second fluid, are fixed on the element 4 to form the housing.

La protubérance ainsi créée permet d'éviter un éventuel déplacement des collecteurs 5, 6 selon la direction longitudinale « L » montrée sur la figure 1, lors du déroulement du procédé de brasage. La déformation, permettant d'obtenir une courbure de la portion 45 vers l'intérieur de l'échangeur de chaleur 1, peut être réalisée à l'aide d'un outil adapté connu dans l'art antérieur. FIG. 2 shows in detail the first wall 3 making it possible to form the casing of an exchange bundle 2 according to the invention. The first wall 3 is provided with a first latch 41 and a second latch 51. Each latch 41, 51 corresponds to a slot 44 made in the wall 3. The presence of the slot 44, within the wall 4, allows the displacement of a portion of the wall 3 in an area surrounding said slot 44. The locks 41, 51 are shown in Figure 2, in a first position. In the first position, each latch 41, 51 is located in the same vertical plane as that of the wall 4. The first position of the latches 41, 51 allows the assembly of the different elements, as shown in FIG. different elements are correctly positioned relative to each other, the locks 41, 51 are deformed to obtain the shape as shown in Figure 3, which corresponds to the second position of the locks 41, 51. In the second position, each latch 41, 51 comprises a portion 45 of the wall 4 which forms a protuberance with respect to the vertical plane of the wall 4, in a direction transverse to the longitudinal direction of the wall 4. The protuberance thus created makes it possible to avoid a possible displacement of the collectors 5, 6 in the longitudinal direction "L" shown in Figure 1, during the course of the brazing process. The deformation, making it possible to obtain a curvature of the portion 45 towards the inside of the heat exchanger 1, can be achieved by means of a suitable tool known in the prior art.
Il convient de noter que la figure 1 montre deux verrous 41, 51, à l'une des extrémités de la paroi 4. Etant donné que le boîtier pour l'échangeur de chaleur 1 dispose de quatre parois, comportant chacune deux extrémités, il existe donc huit verrous (2 x 4) à chaque extrémité de l'échangeur de chaleur 1. It should be noted that FIG. 1 shows two latches 41, 51, at one end of the wall 4. Since the housing for the heat exchanger 1 has four walls, each having two ends, there exists therefore eight bolts (2 x 4) at each end of the heat exchanger 1.
La figure 4 montre l'ensemble de la paroi 3 et du collecteur 5, les verrous 41, 51, étant dans la deuxième position. Les verrous 41, 51 forment la protubérance se dirigeant vers l'intérieur de l'échangeur de chaleur 1, et bloquent le déplacement éventuel du collecteur 5 dans la direction longitudinale « L », tel que montré sur la figure 4. II convient de noter que les autres verrous, présentés sur les autres parois, ne sont pas visibles sur la figure 4. Figure 4 shows the assembly of the wall 3 and the collector 5, the latches 41, 51, being in the second position. The latches 41, 51 form the protuberance directed towards the inside of the heat exchanger 1, and block the possible displacement of the collector 5 in the longitudinal direction "L", as shown in FIG. 4. It should be noted that the other locks, presented on the other walls, are not visible in Figure 4.
