The pipes are connected between two support plates (7) anchored at both ends of the casing, where the casing and the support plates have a substantially rectangular cross-section. Each support plate includes protuberances arranged in proximity to a peripheral zone, where the protuberances (9) includes raised portions that come into contact with a peripheral surface area of the casing.

Description

La présente invention concerne un échangeur thermique pour gaz, en particulier les gaz d'échappement d'un moteur, du type comprenant une pluralité de conduits parallèles disposés à l'intérieur d'un boîtier, au moyen desquels les gaz devant être refroidis par échange thermique avec un fluide de refroidissement circulent, lesdits conduits étant couplés entre deux plaques de support fixées au niveau des deux extrémités dudit boîtier, et le boîtier ainsi que les plaques de support présentant une section sensiblement rectangulaire.The present invention relates to a heat exchanger for gas, in particular the exhaust gas of an engine, of the type comprising a plurality of parallel ducts arranged inside a housing, by means of which the gases to be cooled by exchange thermal circuit with a cooling fluid circulate, said conduits being coupled between two support plates fixed at both ends of said housing, and the housing and the support plates having a substantially rectangular section.

L'invention s'applique tout particulièrement à des échangeurs thermiques dont le boîtier, les plaques de support et les conduits parallèles présentent une section transversale sensiblement rectangulaire. De préférence, elle s'applique à des échangeurs thermiques de petite taille tels que des échangeurs de recirculation des gaz d'échappement d'un moteur (EGRC).The invention is particularly applicable to heat exchangers whose housing, support plates and parallel ducts have a substantially rectangular cross section. Preferably, it applies to small heat exchangers such as engine exhaust gas recirculation (EGRC) exchangers.

Arrière-plan de l'inventionBackground of the invention

Dans certains échangeurs thermiques pour le refroidissement des gaz, par exemple ceux qui sont utilisés dans des systèmes de recirculation des gaz d'échappement jusqu'à l'admission d'un moteur à explosion, les deux moyens qui effectuent des échanges thermiques sont séparés par une paroi.In certain heat exchangers for cooling the gases, for example those used in exhaust gas recirculation systems until the admission of an internal combustion engine, the two means which carry out heat exchanges are separated by a wall.

Plus particulièrement, les gaz circulent dans un ensemble de tubes ou de conduits parallèles disposés à l'intérieur d'un boîtier et ils sont refroidis par échange thermique avec un fluide de refroidissement qui circule en dehors des conduits de passage des gaz.More particularly, the gases circulate in a set of tubes or parallel conduits arranged inside a housing and they are cooled by heat exchange with a cooling fluid which circulates outside the gas passage ducts.

Les tubes sont fixés au niveau de leurs extrémités entre deux plaques de support couplées à chaque extrémité du boîtier. Les deux plaques de support présentent une pluralité d'orifices pour le logement des tubes respectifs.The tubes are fixed at their ends between two support plates coupled to each end of the housing. The two support plates have a plurality of orifices for accommodating the respective tubes.

Les gaz sont amenés au moyen d'un faisceau de tubes de l'échangeur à partir d'un conduit d'admission ; dans la mesure où le diamètre du conduit d'admission est inférieur au diamètre du boîtier et du faisceau de tubes de l'échangeur, il existe entre ces derniers un réservoir d'admission qui est évacué progressivement.The gases are supplied by means of a bundle of tubes of the exchanger from an intake duct; insofar as the diameter of the intake duct is less than the diameter of the housing and the tube bundle of the exchanger, there exists between them an intake tank which is evacuated progressively.

On connaît des échangeurs thermiques dont le boîtier et les plaques de support présentent une section transversale sensiblement rectangulaire. Dans ce cas, le montage de l'échangeur consiste tout d'abord à assembler au préalable l'ensemble formé par le boîtier, la pluralité de tubes et les plaques de support. Par la suite, on poursuit par l'application sur ledit ensemble d'une pâte de soudure, l'assemblage des réservoirs à gaz et la soudure au four de l'échangeur thermique complet.Heat exchangers are known whose housing and support plates have a substantially rectangular cross section. In this case, the assembly of the exchanger consists first of all to assemble beforehand the assembly formed by the housing, the plurality of tubes and the support plates. Thereafter, it continues with the application on said assembly of a solder paste, the assembly of gas tanks and the oven welding of the complete heat exchanger.

Dans la pratique, il a été constaté que les plaques de support assemblées au préalable peuvent subir des déplacements non souhaités au cours du montage du reste des composants, dans la mesure où il n'existe ni soudure ni aucune union mécanique entre les plaques de support et le boîtier avant de mener à bien la soudure au four de la totalité de l'échangeur thermique.In practice, it has been found that the previously assembled support plates can undergo unwanted displacements during assembly of the remaining components, since there is no welding or mechanical union between the support plates. and the housing before carrying out the baking of the entire heat exchanger.

On connaît certaines solutions permettant d'immobiliser les plaques de support au cours de l'assemblage de l'échangeur thermique ; par exemple, les plaques de support peuvent présenter un rebord destiné à mettre en prise le contour du boîtier, ou encore les plaques de support sont mises en prise par le boîtier. Il est également possible d'utiliser la soudure au four ou la soudure au laser pour unir les deux composants.Some solutions are known for immobilizing the support plates during assembly of the heat exchanger; for example, the support plates may have a flange for engaging the contour of the housing, or the support plates are engaged by the housing. It is also possible to use baking or laser welding to join the two components together.

Dans le cas d'échangeurs thermiques dont le boîtier et les conduits présentent une section sensiblement circulaire, une solution connue consiste à effectuer des protubérances au moyen d'un outil servant de poinçon sur la plaque de support. D'une part, les protubérances permettent à l'opérateur d'identifier rapidement la face qui doit être située contre le boîtier, dans la mesure où ladite face est celle qui comprend les protubérances. D'autre part, lesdites protubérances ont également pour fonction d'éviter le mouvement relatif des plaques de support par rapport au boîtier au cours du montage avant la soudure au four. Il est possible d'obtenir cet effet grâce au contact par frottement des protubérances avec la zone périphérique du boîtier, dans la mesure où ces protubérances doivent être effectuées dans une zone proche de la périphérie des plaques de support.In the case of heat exchangers whose housing and ducts have a substantially circular section, a known solution is to make protrusions by means of a tool serving as a punch on the support plate. On one hand, the protuberances allow the operator to quickly identify the face to be located against the housing, insofar as said face is the one that includes the protuberances. On the other hand, said protuberances also have the function of preventing the relative movement of the support plates relative to the housing during the assembly before the welding in the oven. It is possible to achieve this effect through frictional contact of the protuberances with the peripheral zone of the housing, insofar as these protuberances must be made in an area near the periphery of the support plates.

Cependant, dans la pratique, il a été constaté qu'il est très difficile de mécaniser un boîtier présentant une section parfaitement circulaire, dans la mesure où il existe un risque en ce que certaines des protubérances peuvent se trouver en dehors de la zone périphérique du boîtier, ce qui a pour conséquence que les plaques de support se déplacent au cours du montage préalable à la soudure au four.However, in practice, it has been found that it is very difficult to mechanize a housing having a perfectly circular section, to the extent that there is a risk that some of the protuberances may be outside the peripheral zone of the case, which causes the support plates to move during pre-assembly to the baking process.

Description de l'inventionDescription of the invention

L'objet de la présente invention est de résoudre les inconvénients mentionnés ci-dessus, en développant un échangeur thermique qui permet d'immobiliser les plaques de support au cours du montage et de la soudure de l'échangeur.The object of the present invention is to solve the disadvantages mentioned above, by developing a heat exchanger which immobilizes the support plates during assembly and welding of the exchanger.

L'échangeur thermique pour gaz, en particulier les gaz d'échappement d'un moteur, objet de la présente invention, est du type comprenant une pluralité de conduits parallèles disposés à l'intérieur d'un boîtier, au moyen desquels les gaz devant être refroidis par échange thermique avec un fluide de refroidissement circulent, lesdits conduits étant couplés entre deux plaques de support fixées au niveau des deux extrémités dudit boîtier, et le boîtier ainsi que les plaques de support présentant une section sensiblement rectangulaire ; l'échangeur thermique est caractérisé en ce que chaque plaque de support comprend des protubérances disposées à proximité de sa zone périphérique, lesdites protubérances comprenant des reliefs susceptibles d'entrer en contact avec une superficie périphérique du boîtier.The gas heat exchanger, in particular the exhaust gas of an engine, object of the present invention, is of the type comprising a plurality of parallel ducts arranged inside a housing, by means of which the gases in front of being cooled by heat exchange with a cooling fluid circulate, said ducts being coupled between two support plates fixed at both ends of said housing, and the housing and the support plates having a substantially rectangular section; the heat exchanger is characterized in that each support plate comprises protuberances arranged near its peripheral zone, said protuberances comprising reliefs likely to come into contact with a peripheral surface of the housing.

De cette façon, grâce au frottement produit entre les protubérances et la superficie périphérique du boîtier, il est possible d'éviter tout mouvement non souhaité des plaques de support au cours de l'assemblage et de l'application de la soudure au four de l'échangeur thermique.In this way, thanks to the friction produced between the protuberances and the peripheral surface of the housing, it is possible to avoid any unwanted movement of the support plates during the assembly and application of the oven welding. 'heat exchanger.

De manière avantageuse, les protubérances sont disposées de façon symétrique sur chaque plaque de support. De cette façon, il est possible d'empêcher la rotation desdites plaques de support.Advantageously, the protuberances are arranged symmetrically on each support plate. In this way, it is possible to prevent the rotation of said support plates.

Selon un mode de réalisation de l'invention, chaque plaque de support comprend au moins quatre protubérances.According to one embodiment of the invention, each support plate comprises at least four protuberances.

De préférence, chaque plaque de support comprend six protubérances, quatre protubérances étant disposées au niveau de chaque coin de la plaque de support et les deux protubérances restantes étant disposées dans la zone médiane de deux latérales opposées.Preferably, each support plate comprises six protuberances, four protuberances being disposed at each corner of the support plate and the two remaining protuberances being disposed in the middle zone of two opposite sides.

De manière avantageuse, les reliefs des protubérances sont orientés vers l'intérieur de l'échangeur pour assembler les plaques de support avec le boîtier.Advantageously, the reliefs of the protuberances are oriented towards the inside of the exchanger to assemble the support plates with the housing.

De préférence, la hauteur des reliefs est de 0,5 mm avec une tolérance de +0,1 / -0,2 mm ; le diamètre des protubérances est de 2 mm avec une tolérance de +0 / -0,2 mm ; et la distance des protubérances par rapport au bord de la plaque de support est d'approximativement 1,05 mm avec une tolérance de +0,1 / -0 mm.Preferably, the height of the reliefs is 0.5 mm with a tolerance of +0.1 / -0.2 mm; the diameter of the protuberances is 2 mm with a tolerance of +0 / -0.2 mm; and the distance of the protuberances from the edge of the support plate is approximately 1.05 mm with a tolerance of +0.1 / -0 mm.

Description d'un mode de réalisation préféréDescription of a preferred embodiment

Comme représenté sur la figure 1, l'échangeur thermique 1 est constitué d'un boîtier 2 qui contient un faisceau de tubes 3 parallèles, destinés au passage des gaz devant être refroidis. A l'intérieur du boîtier 2, en dehors des tubes 3, un fluide de refroidissement circule, depuis une admission 4 jusqu'à une évacuation (non représentée).As shown on the figure 1 , the heat exchanger 1 consists of a housing 2 which contains a bundle of parallel tubes 3 for the passage of gases to be cooled. Inside the housing 2, outside the tubes 3, a cooling fluid flows from an inlet 4 to an outlet (not shown).

Les gaz devant être refroidis entrent dans l'échangeur 1 à partir d'un conduit d'alimentation 5 et à travers un réservoir d'admission 6, qui est évacué progressivement.The gases to be cooled enter the exchanger 1 from a supply duct 5 and through an intake tank 6, which is discharged progressively.

Le faisceau de tubes 3 est fixé par ses extrémités entre deux plaques de support 7 couplées à chaque extrémité du boîtier 2, la figure 1 représentant celle qui est située au niveau de l'admission. Chaque plaque de support 7 présente une pluralité d'orifices 8 pour le logement des tubes 3 respectifs (se reporter à la figure 2).The bundle of tubes 3 is fixed at its ends between two support plates 7 coupled to each end of the housing 2, the figure 1 representing that which is located at the admission level. Each support plate 7 has a plurality of orifices 8 for accommodating the respective tubes 3 (see FIG. figure 2 ).

De plus, chaque plaque de support 7 comprend un ensemble de protubérances 9 disposées à proximité de sa zone périphérique. Comme représenté sur les figures 3 et 4, lesdites protubérances 9 comprennent des reliefs 10 orientés vers l'intérieur du boîtier 2, susceptibles d'entrer en contact avec une superficie périphérique 11 du boîtier 2 (se reporter à la figure 1).In addition, each support plate 7 comprises a set of protuberances 9 disposed near its peripheral zone. As shown on Figures 3 and 4 , said protuberances 9 comprise reliefs 10 directed towards the inside of the housing 2, capable of coming into contact with a peripheral surface 11 of the housing 2 (refer to FIG. figure 1 ).

Par la suite, les caractéristiques géométriques des protubérances 9 selon le présent mode de réalisation sont décrites :

  • On effectue six protubérances 9 distribuées de façon symétrique, quatre protubérances 9 étant disposées à chaque coin de la plaque de support 7 et les deux autres protubérances 9 restantes étant disposées dans la zone médiane de deux latérales opposées.
  • Les reliefs 10 des protubérances 9 sont orientés vers l'intérieur de l'échangeur 1 pour assembler les plaques de support 7 avec le boîtier 2.
  • La hauteur des reliefs 10 est de 0,5 mm avec une tolérance de +0,1 / -0,2 mm.
  • Le diamètre des protubérances 9 est de 2 mm avec une tolérance de +0 / -0,2 mm.
  • La distance des protubérances 9 par rapport au bord de la plaque de support 7 est d'approximativement 1,05 mm avec une tolérance de +0,1 / -0 mm.
Subsequently, the geometric characteristics of the protuberances 9 according to the present embodiment are described:
  • Six protuberances 9 are distributed symmetrically, with four protuberances 9 being arranged at each corner of the support plate 7 and the remaining two remaining protuberances 9 being arranged in the median zone of two opposite sides.
  • The reliefs 10 of the protuberances 9 are oriented towards the inside of the exchanger 1 to assemble the support plates 7 with the housing 2.
  • The height of the reliefs 10 is 0.5 mm with a tolerance of +0.1 / -0.2 mm.
  • The diameter of the protuberances 9 is 2 mm with a tolerance of +0 / -0.2 mm.
  • The distance of the protuberances 9 from the edge of the support plate 7 is approximately 1.05 mm with a tolerance of +0.1 / -0 mm.

Afin de procéder au montage de l'échangeur thermique 1, il faut tout d'abord procéder à l'assemblage préalable de l'ensemble formé par le boîtier 2, la pluralité de tubes 3 et les plaques de support 7. Par la suite, on procède à l'application sur ledit ensemble d'une pâte de soudure, l'assemblage des réservoirs à gaz 6 et la soudure au four de l'échangeur thermique 1 complet.In order to proceed with the assembly of the heat exchanger 1, it is first necessary to proceed to the preliminary assembly of the assembly formed by the housing 2, the plurality of 3 and the support plates 7. Subsequently, the application is made on the assembly of a solder paste, the assembly of the gas reservoirs 6 and the oven welding of the complete heat exchanger 1.

Grâce au frottement produit entre les protubérances 9 et la superficie périphérique 11 du boîtier 2, il est possible d'immobiliser les plaques de support 7, évitant tout déplacement non souhaité desdites plaques 7 au cours dudit assemblage préalable, ainsi qu'au cours du montage du reste des composants et de la soudure au four finale.Thanks to the friction produced between the protuberances 9 and the peripheral surface 11 of the housing 2, it is possible to immobilize the support plates 7, avoiding any unwanted displacement of said plates 7 during said prior assembly, as well as during assembly the rest of the components and the final oven weld.
