Description

La présente invention concerne un échangeur thermique pour gaz, en particulier pour les gaz d'échappement d'un moteur.The present invention relates to a heat exchanger for gases, in particular for the exhaust gases of an engine.

L'invention s'applique tout spécialement dans les échangeurs thermiques de recirculation des gaz d'échappement d'un moteur (EGRC).The invention applies most especially in engine exhaust gas recirculation (EGRC) heat exchangers.

CONTEXTE DE L'INVENTIONBACKGROUND OF THE INVENTION

La fonction principale des échangeurs EGR est l'échange de chaleur entre les gaz d'échappement et le fluide caloporteur, dans le but de refroidir les gaz.The main function of EGR exchangers is the exchange of heat between the exhaust gases and the coolant, with the aim of cooling the gases.

Actuellement, les échangeurs thermiques EGR sont largement utilisés pour des applications Diesel afin de réduire les émissions et servent aussi dans des applications à essence pour réduire la consommation de carburant.Currently, EGR heat exchangers are widely used in diesel applications to reduce emissions and are also used in gasoline applications to reduce fuel consumption.

Le marché tend à réduire la taille des moteurs et à appliquer les échangeurs de chaleur EGR non seulement dans les applications haute pression (HP) mais aussi dans celles basse pression (LP); toutes les deux ont un impact sur la conception des échangeurs de chaleur EGR. Les constructeurs de véhicules exigent des échangeurs de chaleur EGR avec de meilleurs rendements et, en même temps, l'espace disponible pour placer l'échangeur et ses composants est de plus en plus petit, ce qui les rend de plus en plus difficiles à intégrer.The market tends to downsize engines and apply EGR heat exchangers not only in high pressure (HP) but also in low pressure (LP) applications; both have an impact on the design of EGR heat exchangers. Vehicle manufacturers are demanding EGR heat exchangers with better efficiencies and, at the same time, the space available to place the exchanger and its components is increasingly small, which makes them increasingly difficult to integrate .

En plus, dans de nombreuses applications l'écoulement du fluide caloporteur pour refroidir les gaz d'échappement tend à se réduire bien que les rendements de l'échangeur soient allés en augmentant.In addition, in many applications the flow of heat transfer fluid to cool the exhaust gases tends to be reduced although the yields of the exchanger have increased.

La configuration actuelle des échangeurs EGR présents sur le marché correspond à un échangeur thermique métallique généralement fabriqué en acier inoxydable ou en aluminium.The current configuration of EGR exchangers present on the market corresponds to a metallic heat exchanger generally made of stainless steel or aluminum.

Fondamentalement, il y a deux types d'échangeurs de chaleur EGR: un premier type consiste en un boîtier à l'intérieur duquel on dispose un faisceau de tubes parallèles pour le passage des gaz, le réfrigérant circulant dans le boîtier, à l'extérieur des tubes, et le second type se compose d'une série de plaques parallèles qui constituent les surfaces d'échange de chaleur, de sorte que les gaz d'échappement et le réfrigérant circulent entre deux plaques, en couches alternées, avec possibilité d'inclure des ailettes pour améliorer l'échange de chaleur.Basically, there are two types of EGR heat exchangers: a first type consists of a casing inside which there is a bundle of parallel tubes for the passage of gases, the refrigerant circulating in the casing, outside tubes, and the second type consists of a series of parallel plates which constitute the heat exchange surfaces, so that the exhaust gases and the refrigerant circulate between two plates, in alternating layers, with the possibility of include fins to improve heat exchange.

Dans le cas d'échangeurs de chaleur à faisceau de tubes, l'assemblage entre les tubes et le boîtier peut être de différents types. Généralement, les tubes sont fixés par leurs extrémités entre deux plaques de support raccordées à chaque extrémité du boîtier, les deux plaques de support présentant une pluralité d'orifices pour l'installation des tubes respectifs.In the case of tube bundle heat exchangers, the assembly between the tubes and the casing can be of different types. Generally, the tubes are fixed by their ends between two support plates connected to each end of the casing, the two support plates having a plurality of orifices for the installation of the respective tubes.

Lesdites plaques de support sont fixées à leur tour à des moyens de raccordement avec la ligne de recirculation, qui peuvent consister en un montage en V ou bien en un collet périphérique de raccordement ou bride, en fonction de la conception de la ligne de recirculation dans laquelle est assemblé l'échangeur. Le collet périphérique peut être assemblé avec un réservoir à gaz, de façon à ce que le réservoir à gaz soit une pièce intermédiaire entre le boîtier et le collet, ou bien le collet peut être assemblé directement au boîtier.Said support plates are fixed in turn to means of connection with the recirculation line, which can consist of a V-mounting or else of a peripheral connection collar or flange, depending on the design of the recirculation line in which the heat exchanger is assembled. The peripheral collar can be assembled with a gas tank, so that the gas tank is an intermediate piece between the housing and the collar, or the collar can be assembled directly to the housing.

Dans les deux types d'échangeurs EGR, la plupart de leurs composants sont métalliques, de sorte qu'ils sont assemblés par des moyens mécaniques et ensuite soudés au four ou soudés à l'arc ou au laser pour assurer l'étanchéité appropriée que requiert cette application.In both types of EGR exchangers, most of their components are metallic, so they are assembled by mechanical means and then welded in the oven or welded by arc or laser to ensure the appropriate sealing that requires this application.

Quelques échangeurs EGR comprennent aussi un filtre dans la ligne d'échappement, qui est généralement constitué par un composant indépendant, quoiqu'il puisse être partiellement intégré à l'échangeur EGR.Some EGR exchangers also include a filter in the exhaust line, which generally consists of an independent component, although it may be partially integrated into the EGR exchanger.

Le brevet EP2273095 concerne un échangeur thermique comprenant un filtre de liquide intégré audit échangeur, qui comprend une zone de filtre dépassant d'une surface plane. Ce filtre est configuré comme un joint et est monté entre la bride de raccordement et le réservoir de gaz au moyen d'éléments de visserie.The patent EP2273095 relates to a heat exchanger comprising a liquid filter integrated with said exchanger, which comprises a filter zone protruding from a flat surface. This filter is configured as a gasket and is mounted between the connection flange and the gas tank by means of fasteners.

Le brevet EP2194351 concerne un échangeur thermique comprenant un filtre à particules pour la filtration des gaz d'échappement, structurellement intégré à l'intérieur du tube d'entrée des gaz de l'échangeur thermique.The patent EP2194351 relates to a heat exchanger comprising a particulate filter for the filtration of exhaust gases, structurally integrated inside the gas inlet tube of the heat exchanger.

Le brevet FR2938051 concerne un échangeur thermique qui comprend un filtre logé dans une position choisie de façon à ce que le filtre soit disposé près d'un côté extrême du faisceau tubulaire.The patent FR2938051 relates to a heat exchanger which comprises a filter housed in a position chosen so that the filter is arranged close to an end side of the tube bundle.

Cependant, ces filtres présentent l'inconvénient de nécessiter un processus d'assemblage ardu et lent puisqu'on utilise des joints supplémentaires et une fixation au moyen des éléments de visserie. En outre, leur volume fait augmenter les dimensions de l'échangeur, avec les problèmes qui en résultent pour le montage dans le compartiment moteur.However, these filters have the disadvantage of requiring an arduous and slow assembly process since additional gaskets and fixing by means of screws and bolts are used. In addition, their volume increases the dimensions of the exchanger, with consequent problems for mounting in the engine compartment.

DESCRIPTION DE L'INVENTIONDESCRIPTION OF THE INVENTION

L'objectif de l'échangeur thermique pour gaz, en particulier les gaz d'échappement d'un moteur, selon la présente invention est de résoudre les inconvénients que présentent les échangeurs connus dans l'art, en offrant un filtre à particules plus économique et simple à assembler dans l'échangeur.The objective of the heat exchanger for gases, in particular the exhaust gases of an engine, according to the present invention is to solve the drawbacks exhibited by the exchangers known in the art, by offering a more economical particulate filter. and simple to assemble in the exchanger.

L'invention concerne un échangeur thermique pour gaz selon l'objet de la revendication indépendante 1.The invention relates to a gas heat exchanger according to the subject of independent claim 1.

De cette façon, on obtient un filtre totalement intégré au réservoir de gaz en une unique pièce, ce qui facilite ainsi son assemblage au boîtier de l'échangeur.In this way, a filter is obtained which is completely integrated into the gas tank in a single piece, which thus facilitates its assembly to the housing of the exchanger.

Le filtre est intégré au réservoir de gaz par soudage. On obtient ainsi une fixation du filtre au réservoir de gaz plus simple, puisqu'il n'est pas nécessaire que le filtre ait un collet métallique ou des pièces intermédiaires de fixation, pas plus que des éléments de visserie, pour être assemblé au réservoir de gaz, comme cela se passait avec les filtres connus.The filter is integrated into the gas tank by welding. A simpler fixing of the filter to the gas tank is thus obtained, since it is not necessary for the filter to have a metal collar or intermediate fixing parts, no more than screws and bolts, to be assembled to the gas tank. gas, as happened with the known filters.

Également, le réservoir de gaz peut être assemblé directement par brasage au four au noyau de l'échangeur thermique et il n'est pas nécessaire d'utiliser une pièce séparée assemblée par des éléments de visserie comme dans l'art antérieur.Also, the gas tank can be assembled directly by furnace brazing to the core of the heat exchanger and it is not necessary to use a separate piece assembled by hardware elements as in the prior art.

De préférence, le filtre est assemblé au réservoir de gaz par soudage par points ou soudage à l'arc.Preferably, the filter is assembled to the gas tank by spot welding or arc welding.

Facultativement, le filtre est en outre assemblé au réservoir de gaz par brasage au four. En général, il suffit d'un assemblage par soudage par points ou à l'arc pour garantir une fixation correcte du filtre. Néanmoins, il est possible d'améliorer la fixation par un brasage au four additionnel.Optionally, the filter is further joined to the gas tank by furnace brazing. In general, only an assembly by spot or arc welding is sufficient to guarantee a correct fixing of the filter. However, it is possible to improve the fixing by additional furnace brazing.

Conformément à l'invention, ledit écran comprend une aile périphérique plate prévue pour l'assemblage d'un seul tenant avec le réservoir de gaz.According to the invention, said screen comprises a flat peripheral wing provided for assembly in one piece with the gas tank.

La configuration en forme d'écran concave permet d'augmenter la superficie de filtration et d'autre part la surface plane de l'aile périphérique facilite la fixation du filtre au réservoir de gaz par soudage, sans qu'il soit besoin de pièces intermédiaires ni d'éléments de visserie.The configuration in the form of a concave screen makes it possible to increase the filtration area and on the other hand the flat surface of the peripheral wing facilitates the fixing of the filter to the gas tank by welding, without the need for intermediate parts. nor any hardware.

Le réservoir de gaz comprend un bord périphérique plat dans sa partie intérieure, destiné à recevoir l'aile périphérique du filtre en vue de leur assemblage l'un à l'autre. De cette façon, on garantit une fixation par soudure permanente et robuste entre les deux pièces.The gas tank comprises a flat peripheral edge in its inner part, intended to receive the peripheral wing of the filter with a view to their assembly to one another. In this way, a permanent and robust welding attachment is guaranteed between the two parts.

Les avantages que procure la présente invention sont résumés ci-après:

  • On obtient un filtre plus économique et plus facile à fabriquer, formé seulement par l'écran de filtration qui comprend l'aile périphérique constituée de la même matière. Néanmoins, si on le souhaite on peut aussi inclure un plan métallique autour de l'écran.
  • L'intégration du filtre simplifie la conception de l'échangeur en éliminant la nécessité d'inclure un collet, un joint et des éléments de visserie. Le résultat est une réduction significative du coût de l'assemblage.
  • L'intégration du filtre au réservoir de gaz implique un moindre volume de l'échangeur thermique par comparaison avec d'autres solutions qui nécessitent un collet ou une pièce supplémentaire.
  • En réduisant le nombre de pièces, on simplifie le processus d'assemblage de l'échangeur et aussi parce que le processus de soudage est beaucoup plus rapide que le processus avec éléments de visserie.
The advantages provided by the present invention are summarized below:
  • A more economical and easier to manufacture filter is obtained, formed only by the filtration screen which comprises the peripheral wing made of the same material. However, if desired, a metallic plane can also be included around the screen.
  • The integration of the filter simplifies the design of the exchanger by eliminating the need to include a collar, gasket and hardware. The result is a significant reduction in assembly cost.
  • The integration of the filter to the gas tank implies a lower volume of the heat exchanger compared to other solutions which require a collar or an additional part.
  • By reducing the number of parts, the heat exchanger assembly process is simplified and also because the welding process is much faster than the process with fasteners.

De cette façon, en obtenant une unique pièce, on facilite son assemblage au boîtier 3 de l'échangeur 1.The exchanger 1 also comprises a particulate filter 7 for filtering the exhaust gases, integrated into the gas tank 6 and forming a single inseparable part capable of being fitted to the housing 3 of the exchanger. In this way, by obtaining a single piece, it facilitates its assembly to the housing 3 of the exchanger 1.

Le filtre 7 est intégré au réservoir de gaz 6 par soudage, que ce soit par soudage par points ou par soudage à l'arc. On obtient ainsi une fixation du filtre 7 au réservoir de gaz 6 plus simple, puisqu'il n'est pas nécessaire que le filtre 7 ait un collet métallique ou des pièces intermédiaires de fixation, pas plus que des éléments de visserie, pour être assemblé au réservoir de gaz 6.The filter 7 is integrated into the gas tank 6 by welding, either by spot welding or by arc welding. A simpler fixing of the filter 7 to the gas tank 6 is thus obtained, since it is not necessary for the filter 7 to have a metal collar or intermediate fixing parts, no more than fasteners, to be assembled. to the gas tank 6.

En général, il suffit d'un assemblage par soudage par points ou à l'arc pour garantir une fixation correcte du filtre 7. Néanmoins, pour améliorer la fixation du filtre 7 au réservoir de gaz 6 on peut en outre appliquer un brasage au four.In general, an assembly by spot or arc welding is sufficient to ensure correct fixing of the filter 7. Nevertheless, to improve the fixing of the filter 7 to the gas tank 6, it is also possible to apply furnace brazing. .

Comme on peut s'en rendre compte sur les figures 2 à 6, le filtre 7 comprend un écran 8 de configuration concave en guise de plateau, avec une aile périphérique 9 plate prévue pour son assemblage d'un seul tenant avec le réservoir de gaz 6. La configuration en forme d'écran 8 concave permet d'augmenter la superficie de filtration et d'autre part la surface plane de l'aile périphérique 9 facilite la fixation du filtre 7 au réservoir de gaz 6 par soudage, sans qu'i soit besoin de pièces intermédiaires ni d'éléments de visserie.As can be seen from the figures 2 to 6 , the filter 7 comprises a screen 8 of concave configuration as a plate, with a flat peripheral wing 9 provided for its assembly in one piece with the gas tank 6. The configuration in the form of a concave screen 8 makes it possible to increasing the filtration area and on the other hand the flat surface of the peripheral wing 9 facilitates the fixing of the filter 7 to the gas tank 6 by welding, without the need for intermediate parts or fasteners.

Le réservoir de gaz 6 comprend dans sa partie intérieure un bord périphérique 10 plat destiné à recevoir l'aile périphérique 9 du filtre 7 en vue de leur assemblage l'un à l'autre. De cette façon, on garantit une fixation par soudure permanente et robuste entre les deux pièces.The gas tank 6 comprises in its inner part a flat peripheral edge 10 intended to receive the peripheral wing 9 of the filter 7 with a view to their assembly to one another. In this way, a permanent and robust welding attachment is guaranteed between the two parts.

Également, le réservoir de gaz 6 comprend un autre collet 11 prévu pour s'emboîter et s'assembler avec le bord du boîtier 3, comme on peut le voir sur la figure 3.Also, the gas tank 6 includes another collar 11 provided to fit and assemble with the edge of the box 3, as can be seen in the picture 3 .
