Description

L'invention se rapporte au domaine des échangeurs de chaleur, en particulier pour véhicules automobiles.The invention relates to the field of heat exchangers, in particular for motor vehicles.

L'invention concerne plus spécifiquement une plaque collectrice pour une boîte collectrice d'un échangeur de chaleur, tel qu'un radiateur ou un échangeur de suralimentation. Généralement, un échangeur de chaleur comprend un faisceau de tubes et deux boîtes collectrices de part et d'autre des tubes, chaque boîte collectrice comprenant une plaque collectrice pour la réception des tubes et un couvercle fixé sur la plaque. On comprend que la liaison entre le couvercle et la plaque collectrice doit être étanche, c'est pourquoi on interpose un joint d'étanchéité entre ces deux pièces.The invention more specifically relates to a header plate for a header box of a heat exchanger, such as a radiator or a charge exchanger. Generally, a heat exchanger comprises a bundle of tubes and two manifolds on either side of the tubes, each manifold comprising a header plate for receiving the tubes and a cover fixed on the plate. It is understood that the connection between the cover and the header plate must be sealed, which is why a seal is interposed between these two parts.

Généralement, la plaque collectrice comprend une gorge périphérique formée par une partie protubérante emboutie, portant les ouvertures de réception des tubes de chaleur et appelée médaillon. Cette gorge s'étend de façon continue sur toute la périphérie de la plaque et permet de loger et positionner le joint avant de rapporter le couvercle. Toutefois, une telle gorge périphérique n'est pas toujours présente de façon continue sur la périphérie de la plaque collectrice. On connait par exemple du document FR2938052 A1 une plaque collectrice présentant une gorge périphérique interrompue au niveau des extrémités longitudinales de la plaque collectrice. Dans ces zones d'extrémité où la gorge est interrompue, le joint est alors positionné directement sur les tubes d'extrémité.Generally, the header plate comprises a peripheral groove formed by a protruding part stamped, carrying the receiving openings of heat tubes and called medallion. This groove extends continuously over the entire periphery of the plate and allows to house and position the seal before bringing the cover. However, such a peripheral groove is not always present continuously on the periphery of the header plate. We know, for example, of the document FR2938052 A1 a collector plate having a peripheral groove interrupted at the longitudinal ends of the collector plate. In these end zones where the groove is interrupted, the seal is then positioned directly on the end tubes.

Or, il se trouve que les tubes de chaleur peuvent avoir une dimension qui varie selon les véhicules, si bien que les plaques collectrices ont des configurations qui varient. On souhaite toutefois avoir une plaque collectrice de forme générale identique quelle que soit la taille des tubes, de façon à standardiser autant que possible la configuration des boîtes collectrices sur les véhicules, par exemple en utilisant un couvercle standard à rapporter sur la plaque. Dans l'art antérieur précité, les tubes d'extrémités permettent de maintenir le joint d'étanchéité car la longueur de ces tubes est similaire à la dimension transversale de la plaque. La présente invention répond à un besoin particulier d'une plaque collectrice qui comporte des tubes d'extrémité trop courts pour maintenir le moyen d'étanchéité contre les bords de la plaque collectrice.However, it turns out that the heat tubes may vary in size depending on the vehicle, so that the collector plates have varying configurations. However, it is desired to have a collector plate of identical general shape regardless of the size of the tubes, so as to standardize as much as possible the configuration of the manifolds on the vehicles, for example by using a standard cover to report on the plate. In the aforementioned prior art, the end tubes make it possible to maintain the seal because the length of these tubes is similar to the transverse dimension of the plate. The present invention addresses a particular need for a header plate which has end tubes too short to hold the sealing means against the edges of the header plate.

Ainsi, la présente invention a notamment pour but de proposer une plaque collectrice permettant de positionner un joint d'étanchéité même avec des tubes de dimension plus petite que le couvercle.Thus, the present invention is intended to provide a header plate for positioning a seal even with tubes of dimension smaller than the lid.

A cet effet, l'invention a pour objet une plaque collectrice pour une boîte collectrice d'un échangeur de chaleur de véhicule automobile, la plaque présentant une dimension transversale et une dimension longitudinale et comportant : un logement périphérique de réception d'un moyen d'étanchéité, disposé sur la périphérie de la plaque collectrice ; une pluralité d'ouvertures pour le passage de tubes d'échange thermique, au moins l'une des ouvertures ne s'étendant que partiellement dans la dimension transversale de la plaque ; la plaque comportant en outre au moins une protubérance locale de positionnement du moyen d'étanchéité, délimitant une partie du logement de réception du moyen d'étanchéité, ladite protubérance locale étant agencée dans le prolongement, selon la direction transversale, d'une ouverture pour le passage d'un tube ne s'étendant que partiellement dans la dimension transversale de la plaque, une partie proéminente accueillant une majorité des ouvertures de passage de tubes d'échange thermique, et une partie disposée en retrait par rapport à la partie proéminente, la partie en retrait s'étendant depuis la partie proéminente jusqu'à un bord transversal de la plaque, le logement périphérique de réception du moyen d'étanchéité étant délimité, en outre de la protubérance locale, par une gorge délimitée par une partie proéminente accueillant une majorité des ouvertures de passage de tubes d'échange thermique, et la protubérance locale étant ménagée sur la partie en retrait, la partie en retrait comprenant éventuellement un plan incliné.To this end, the subject of the invention is a collecting plate for a collecting box of a motor vehicle heat exchanger, the plate having a transverse dimension and a longitudinal dimension and comprising: a peripheral housing for receiving a means for receiving a sealing, disposed on the periphery of the collector plate; a plurality of openings for the passage of heat exchange tubes, at least one of the openings extending only partially in the transverse dimension of the plate; the plate further comprising at least one local protrusion for positioning the sealing means, delimiting a portion of the receiving housing of the sealing means, said local protuberance being arranged in the extension, in the transverse direction, of an opening for the passage of a tube extending only partially in the transverse dimension of the plate, a prominent portion accommodating a majority of the heat exchange tube passage openings, and a part set back with respect to the protruding part, the recessed portion extending from the protruding portion to a transverse edge of the plate, the peripheral receiving housing of the sealing means being delimited, in addition to the local protuberance, by a groove defined by a prominent prominent portion a majority of the passage openings of heat exchange tubes, and the local protuberance being arranged on the p recessed part, the recessed part optionally comprising an inclined plane.

Ainsi, on propose de ménager une protubérance locale pour assurer le positionnement et la mise en place du moyen d'étanchéité, ce qui est particulièrement intéressant dans le cas où une plaque collectrice ne présente pas de gorge périphérique continue et comporte des ouvertures d'extrémité, pour le passage de tubes, dont la longueur ne correspond pas à la largeur de la plaque. On peut ainsi positionner le joint et faciliter sa mise en place. Et quelle que soit la largeur des tubes on peut utiliser un couvercle standard.Thus, it is proposed to provide a local protuberance to ensure the positioning and placement of the sealing means, which is particularly advantageous in the case where a header plate has no continuous peripheral groove and has end openings , for the passage of tubes, the length of which does not correspond to the width of the plate. It can thus position the seal and facilitate its implementation. And whatever the width of the tubes one can use a standard lid.

On entend par « protubérance locale » une saillie rapportée sur ou venue de matière avec la plaque collectrice et ne s'étendant pas d'un bout à l'autre d'un côté transversal ou longitudinal de la plaque. En particulier, la protubérance locale se distingue d'une gorge périphérique continue. On entend par ailleurs par « ouverture ne s'étendant que partiellement dans la dimension transversale de la plaque » une ouverture de passage d'un tube qui ne s'étend pas suffisamment transversalement pour être capable de positionner le moyen d'étanchéité avant de rapporter le couvercle sur la plaque. En d'autres termes, une telle ouverture ne s'étend pas d'un bord longitudinal à l'autre du logement de réception du moyen d'étanchéité, mais uniquement sur une partie de cette distance.The term "local protuberance" means a projection attached to or integral with the header plate and not extending from one end to the other of a transverse or longitudinal side of the plate. In particular, the local protuberance is distinguished from a continuous peripheral groove. Furthermore, the term "opening extending only partially in the transverse dimension of the plate" means a passage opening of a tube which does not extend sufficiently transversely to be able to position the sealing means before reporting the lid on the plate. In other words, such an opening does not extend from one longitudinal edge to the other of the receiving housing of the sealing means, but only over part of this distance.

On notera que, généralement, les ouvertures de passage de tubes ont une section oblongue et s'étendent toutes parallèlement les unes aux autres, dans la direction transversale de la plaque. Par ailleurs, le moyen d'étanchéité est généralement un joint d'étanchéité ayant un contour fermé, destiné à assurer l'étanchéité de la jonction couvercle / plaque collectrice, tout particulièrement l'étanchéité à l'air.It should be noted that, generally, the openings for the passage of tubes have a oblong section and extend all parallel to each other, in the transverse direction of the plate. Furthermore, the sealing means is generally a seal having a closed contour, intended to seal the junction cover / collector plate, especially airtightness.

La protubérance locale permet donc de compenser la réduction de taille du tube utilisé.The local protuberance thus makes it possible to compensate for the reduction in size of the tube used.

La partie proéminente est une partie plane centrale qui émerge de la gorge, elle est généralement emboutie, elle peut être appelée « médaillon ».The prominent part is a central flat part that emerges from the throat, it is usually embossed, it can be called "medallion".

La partie en retrait présente l'avantage de faciliter l'emboutissage de la plaque collectrice. En outre, la partie en retrait porte de préférence une ou plusieurs ouvertures de passage de tubes, si bien qu'il est possible de prévoir des ouvertures au voisinage très proche de l'extrémité longitudinale de la plaque. Par ailleurs, cette partie en retrait permet de faciliter l'assemblage du moyen d'étanchéité sur la plaque collectrice.The recessed portion has the advantage of facilitating the stamping of the collector plate. In addition, the recessed portion preferably carries one or more openings for passage of tubes, so that it is possible to provide openings in the vicinity very close to the longitudinal end of the plate. Moreover, this recessed portion facilitates the assembly of the sealing means on the header plate.

La plaque telle que définie ci-dessus peut en outre comporter l'une ou plusieurs des caractéristiques suivantes, prises seules ou en combinaison.

  • Ladite protubérance locale est disposée à une extrémité longitudinale de la plaque.
  • La plaque comprend au moins deux protubérances locales agencées de part et d'autre d'une ouverture ne s'étendant que partiellement dans la dimension transversale de la plaque.
  • La plaque comprend deux ouvertures d'extrémité disposées aux deux extrémités longitudinales de la plaque, la plaque comprenant une protubérance locale en regard de chacune des ouvertures d'extrémité. Eventuellement, la plaque peut comprendre deux protubérances locales en regard de chacune des ouvertures d'extrémité.
  • La protubérance locale est réalisée par emboutissage de la plaque.
  • La protubérance locale est agencée dans au moins un coin périphérique de la plaque collectrice.
  • La protubérance locale a une paroi sensiblement verticale de façon à maintenir le moyen d'étanchéité sur la plaque, notamment avant de rapporter un couvercle sur la plaque. La protubérance locale se présente par exemple sous la forme d'un bossage dont une des parois est plane.
The plate as defined above may further comprise one or more of the following features, taken alone or in combination.
  • Said local protuberance is disposed at a longitudinal end of the plate.
  • The plate comprises at least two local protuberances arranged on either side of an opening extending only partially in the transverse dimension of the plate.
  • The plate comprises two end openings disposed at both longitudinal ends of the plate, the plate comprising a local protuberance facing each of the end openings. Optionally, the plate may comprise two local protuberances facing each of the end openings.
  • The local protuberance is made by stamping the plate.
  • The local protuberance is arranged in at least one peripheral corner of the collector plate.
  • The local protuberance has a substantially vertical wall so as to maintain the sealing means on the plate, in particular before bringing a cover on the plate. The local protuberance is for example in the form of a boss whose one wall is flat.

L'invention a également pour objet une boîte collectrice d'un échangeur de chaleur comportant une plaque collectrice telle que présentée ci-dessus, un couvercle fixé sur la plaque et un moyen d'étanchéité, le moyen d'étanchéité étant maintenu entre le couvercle et la protubérance locale de positionnement.The invention also relates to a manifold of a heat exchanger comprising a header plate as presented above, a cover fixed to the plate and a sealing means, the sealing means being held between the cover and the local positioning protrusion.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins dans lesquels :

  • la figure 1 est une vue en perspective partielle d'une plaque collectrice selon un mode de réalisation,
  • la figure 2 est une vue schématique de haut de la plaque collectrice de la figure 1 munie d'un moyen d'étanchéité, et
  • la figure 3 est une vue en coupe partielle transversale selon l'axe A-A de la plaque collectrice de la figure 2 sur laquelle est fixé un couvercle.
The invention will be better understood on reading the description which follows, given solely by way of example and with reference to the drawings in which:
  • the figure 1 is a partial perspective view of a header plate according to one embodiment,
  • the figure 2 is a schematic top view of the collector plate of the figure 1 provided with a sealing means, and
  • the figure 3 is a partial cross-sectional view along the axis AA of the collector plate of the figure 2 on which is fixed a lid.

On a représenté sur la figure 1 une plaque collectrice 2 pour une boîte collectrice d'un échangeur de chaleur. Cet échangeur de chaleur est utilisé dans un véhicule automobile, il s'agit par exemple d'un radiateur ou d'un échangeur de chaleur d'air de suralimentation. La boîte collectrice est disposée à l'extrémité d'une pluralité de tubes de chaleur faisant partie de l'échangeur. Cette boîte collectrice comprend la plaque collectrice 2, un couvercle 25 fixé par sertissage sur la plaque collectrice 2, ainsi qu'un moyen d'étanchéité 17 disposé entre la plaque 2 et le couvercle 25.We have shown on the figure 1 a collector plate 2 for a collector box of a heat exchanger. This heat exchanger is used in a motor vehicle, it is for example a radiator or a charge air heat exchanger. The header is disposed at the end of a plurality of heat tubes forming part of the exchanger. This box The manifold includes the header plate 2, a crimped cover 25 on the header plate 2, and a seal 17 disposed between the plate 2 and the cover 25.

La plaque collectrice 2 a une forme générale sensiblement rectangulaire, définissant une dimension transversale T et une dimension longitudinale L. Elle est délimitée par des bords longitudinaux 8a, 8b et des bords transversaux, dont seul un bord 8c est représenté sur la figure 1. La plaque comporte des dents de sertissage 10, localisées sur les bords 8a, 8b, 8c de la plaque, pour son assemblage avec le couvercle 25. La plaque collectrice 2 comporte par ailleurs une pluralité d'ouvertures 4 pour le passage de tubes d'échange thermique. Les ouvertures 4 sont de forme allongée, elles ont une section oblongue allongée s'étendant dans la direction transversale T de la plaque 2.The collector plate 2 has a generally rectangular general shape, defining a transverse dimension T and a longitudinal dimension L. It is delimited by longitudinal edges 8a, 8b and transverse edges, of which only an edge 8c is shown on FIG. figure 1 . The plate comprises crimping teeth 10, located on the edges 8a, 8b, 8c of the plate, for its assembly with the cover 25. The manifold plate 2 also comprises a plurality of openings 4 for the passage of tubes. heat exchange. The openings 4 are of elongated shape, they have an elongated oblong section extending in the transverse direction T of the plate 2.

Dans cet exemple, chacune des ouvertures 4 ne s'étend que partiellement dans la dimension transversale T de la plaque 2, et leur position est décentrée sur la plaque 2 dans la direction transversale T. En effet, les ouvertures 4 sont réparties le long d'un bord longitudinal 8a de la plaque 2 et n'atteignent pas l'autre bord longitudinal opposé 8b, car elles sont configurées pour recevoir des tubes de dimension plus petite que d'autres tubes reçus par une plaque collectrice similaire à la plaque 2.In this example, each of the openings 4 extends only partially in the transverse dimension T of the plate 2, and their position is off-center on the plate 2 in the transverse direction T. In fact, the openings 4 are distributed along the a longitudinal edge 8a of the plate 2 and do not reach the other opposite longitudinal edge 8b, because they are configured to receive tubes of smaller size than other tubes received by a similar plate to the plate 2.

Toujours dans cet exemple, la plaque collectrice 2 est sensiblement symétrique par rapport à son un axe central transversal et comprend une partie proéminente 6, également appelée « médaillon », accueillant une majorité des ouvertures 4 de passage de tubes d'échange thermique. La hauteur de la partie proéminente 6 est sensiblement équivalente à celle des bords longitudinaux 8a, 8b de la plaque. Cette partie proéminente 6 est réalisée par emboutissage de la plaque. Deux plans inclinés 12 s'étendent longitudinalement de part et d'autres de cette partie proéminente 6, et le bas de chaque plan incliné 12 est prolongé par une partie plane horizontale appelée zone d'extrémité 13. Dans cet exemple, chaque plan incliné 12 porte deux ouvertures 4 et chaque zone d'extrémité 13 porte une ouverture 18, appelée ouverture d'extrémité (toutefois, elle pourrait en comporter plusieurs). On comprend que chaque plan incliné 12 forme avec la zone d'extrémité 13 une partie dite « en retrait », disposée en retrait par rapport à la partie proéminente 6 et s'étendant depuis cette partie 6 jusqu'aux bords transversaux 8c de la plaque 2.Still in this example, the collector plate 2 is substantially symmetrical with respect to its transverse central axis and comprises a prominent portion 6, also called "medallion", accommodating a majority of the openings 4 for the passage of heat exchange tubes. The height of the prominent portion 6 is substantially equivalent to that of the longitudinal edges 8a, 8b of the plate. This prominent portion 6 is made by stamping the plate. Two inclined planes 12 extend longitudinally on either side of this prominent portion 6, and the bottom of each inclined plane 12 is extended by a horizontal flat portion called end zone 13. In this example, each inclined plane 12 has two openings 4 and each end zone 13 carries an opening 18, called end opening (however, it could include several). It will be understood that each inclined plane 12 forms with the end zone 13 a so-called "recessed" portion, set back with respect to the protruding portion 6 and extending from this portion 6 to the transverse edges 8c of the plate 2.

Par ailleurs, la plaque collectrice 2 comprend une protubérance locale 20 de positionnement du moyen d'étanchéité 17. Dans cet exemple, la plaque 2 comprend deux protubérances locales 20 (dont une seule est visible sur les figures), chacune étant ménagée dans le prolongement des ouvertures d'extrémité 18 dans la direction transversale T. En d'autres termes, chaque protubérance locale 20 est agencée dans un coin périphérique de la plaque collectrice 2. La protubérance locale 20 est réalisée par emboutissage de la plaque 2. Chaque protubérance locale 20 a une paroi sensiblement verticale 21, de façon à servir de surface d'appui pour le moyen d'étanchéité 17 pour le maintenir sur la plaque 2, comme cela est décrit dans la suite.Furthermore, the manifold plate 2 comprises a local protrusion 20 for positioning the sealing means 17. In this example, the plate 2 comprises two local protuberances 20 (only one of which is visible in the figures), each being arranged in the extension end openings 18 in the transverse direction T. In other words, each local protuberance 20 is arranged in a peripheral corner of the header plate 2. The local protuberance 20 is made by stamping the plate 2. Each local protuberance 20 has a substantially vertical wall 21, so as to serve as a bearing surface for the sealing means 17 to maintain it on the plate 2, as described below.

Comme on peut le voir sur la figure 2, la partie proéminente 6 est délimitée par des bords longitudinaux 14 qui sont verticaux et parallèles aux bords longitudinaux 8a, 8b de la plaque. Des gorges longitudinales 16 sont ainsi délimitées par les bords longitudinaux 14 de la partie proéminente 6 et par les bords longitudinaux 8a, 8b de la plaque 2. Ces gorges longitudinales 16 délimitent deux parties longitudinales d'un logement périphérique de réception du moyen d'étanchéité 17, disposé sur la périphérie de la plaque collectrice 2. Plus précisément, le moyen d'étanchéité 17 est un joint ayant un contour fermé, de forme sensiblement rectangulaire, similaire à la forme de la périphérie de la plaque 2. Les gorges longitudinales 16 sont aptes à recevoir les grands côtés du moyen d'étanchéité 17. Le logement périphérique de réception du moyen d'étanchéité 17 comprend également deux parties transversales, disposées à chaque extrémité longitudinale de la plaque collectrice 2. Ces parties transversales du logement comprennent une première partie transversale 22, délimitée par l'ouverture d'extrémité 18 et le bord transversal 8c de la plaque 2. Les parties transversales du logement comprennent par ailleurs une seconde partie 24, délimitée par le bord transversal 8c de la plaque et la protubérance locale 20. La première et la seconde parties transversales 22, 24 du logement permettent de recevoir un petit côté du moyen d'étanchéité 17. Ainsi, on comprend que le logement périphérique de réception du moyen d'étanchéité 17 est composé principalement, dans cet exemple, des deux parties longitudinales délimitées par les gorges longitudinales 16 et des premières et secondes parties transversales 22, 24, disposées à chaque extrémité longitudinale de la plaque 2, en étant délimitées notamment par les bords transversaux 8c de la plaque.As can be seen on the figure 2 , the protruding portion 6 is delimited by longitudinal edges 14 which are vertical and parallel to the longitudinal edges 8a, 8b of the plate. Longitudinal grooves 16 are thus delimited by the longitudinal edges 14 of the protruding part 6 and by the longitudinal edges 8a, 8b of the plate 2. These longitudinal grooves 16 delimit two longitudinal portions of a peripheral housing for receiving the sealing means. 17, disposed on the periphery of the header plate 2. More specifically, the sealing means 17 is a seal having a closed contour, of substantially rectangular shape, similar to the shape of the periphery of the plate 2. The longitudinal grooves 16 are suitable for receiving the long sides of the sealing means 17. The peripheral receiving housing of the sealing means 17 also comprises two transverse portions disposed at each longitudinal end of the header plate 2. These transverse portions of the housing comprise a first transverse portion 22, delimited by the end opening 18 and the transverse edge 8c of the plate 2. The transverse portions of the housing further comprise a second portion 24, delimited by the transverse edge 8c of the plate and the local protuberance 20. The first and second transverse portions 22, 24 of the housing allow to receive a small side of the sealing means 17. Thus, it will be understood that the peripheral receiving housing of the sealing means 17 is composed mainly, in this example, of the two longitudinal portions delimited by the longitudinal grooves 16 and first and second transverse portions 22, 24 , arranged at each longitudinal end of the plate 2, being defined in particular by the transverse edges 8c of the plate.

On notera que la plaque collectrice 2 peut avantageusement être réalisée à partir d'une bande de tôle, toutes les opérations relatives à sa fabrication et à celle des ouvertures 4, des bords 8a, 8b, 8c, des protubérances locales 20 et de toutes les formes qui la composent étant réalisées par emboutissage, découpage et/ou pliage et autres techniques de mise en forme des métaux en feuille. La protubérance locale 20 pourrait éventuellement être une pièce rapportée, en étant collée ou fixée par tout moyen adapté.It will be noted that the collecting plate 2 can advantageously be made from a sheet metal strip, all the operations relating to its manufacture and that of the openings 4, the edges 8a, 8b, 8c, the local protuberances 20 and all the its forms being made by stamping, cutting and / or folding and other forming techniques of sheet metals. The local protuberance 20 could possibly be an insert, being glued or fixed by any suitable means.

La plaque collectrice 2 est assemblée au couvercle 25 de la façon suivante, en référence à la figure 3. On rapporte tout d'abord le moyen d'étanchéité 17 à l'intérieur du logement de réception composé principalement des gorges 16 et des parties 22, 24. A cet effet, le moyen d'étanchéité 17 est étiré et vient en particulier en butée contre la surface d'appui verticale 21 de la protubérance locale 20 de façon à le maintenir sur la plaque, notamment avant de rapporter le couvercle 25. Une fois le moyen d'étanchéité 17 positionné, on rapporte le couvercle 25 en plaquant son bord 26 dans le logement de réception 16, 22, 24, au-dessus du moyen d'étanchéité 17. Puis on fixe le couvercle 25 par sertissage des dents 10 sur le bord 26 du couvercle 25. Ce sertissage permet de comprimer le moyen d'étanchéité 17 contre la plaque collectrice à l'intérieur du logement de réception 16, 22, 24, et ainsi d'assurer une étanchéité à l'air. Dans l'exemple de la figure 3, l'étanchéité est réalisée au regard des dents de sertissage 10, par prise en sandwich du bord 26 du couvercle et du moyen d'étanchéité 17 entre les dents 10 et une zone 28 de la plaque collectrice 2, correspondant au fond de la gorge délimitée par la protubérance locale 20 et le bord transversal 8c.The collector plate 2 is assembled to the cover 25 in the following manner, with reference to the figure 3 . First of all, the sealing means 17 are reported inside the receiving housing composed mainly of the grooves 16 and the parts 22, 24. For this purpose, the sealing means 17 is stretched and comes into abutment in particular. against the vertical bearing surface 21 of the local protuberance 20 so as to hold it on the plate, in particular before bringing back the lid 25. Once the sealing means 17 is positioned, the lid 25 is reported by pressing its edge 26 in the reception housing 16, 22, 24, above the sealing means 17. Then the cover 25 is fixed by crimping the teeth 10 on the edge 26 of the cover 25. This crimping makes it possible to compress the sealing means 17 against the manifold plate inside the receiving housing 16, 22, 24, and thus to ensure airtightness. In the example of the figure 3 , sealing is performed against the crimping teeth 10, by sandwiching the edge 26 of the cover and the sealing means 17 between the teeth 10 and a zone 28 of the collector plate 2, corresponding to the bottom of the throat delimited by the local protuberance 20 and the transverse edge 8c.

Selon un autre exemple de réalisation, les ouvertures d'extrémité 18 de la plaque collectrice 2, voire toutes les ouvertures 4, sont centrées dans la direction transversale T de la plaque 2 et une protubérance locale 20 est présente de part et d'autre de chaque ouverture d'extrémité 18. En d'autres termes, la plaque collectrice comprend une protubérance locale 20 à chacun de ses coins.According to another exemplary embodiment, the end openings 18 of the header plate 2, or even all the openings 4, are centered in the transverse direction T of the plate 2 and a local protuberance 20 is present on either side of the plate 2. each end opening 18. In other words, the header plate comprises a local protuberance 20 at each of its corners.

Selon encore une variante de réalisation, les protubérances locales sont des pions rapportés par soudage, brasage, collage etc, sur la plaque collectrice ou encore des pions venus de matière avec le reste de la plaqueAccording to another variant embodiment, the local protuberances are pions reported by welding, brazing, gluing etc, on the collector plate or pawns from material with the rest of the plate

On notera que la plaque collectrice est particulièrement avantageuse en ce qu'elle permet de positionner un moyen d'étanchéité 17 sans pour autant requérir des ouvertures 4, 18 pour le passage de tubes s'étendant sur toute la dimension transversale de la plaque, ce qui permet d'améliorer la standardisation des configurations sur les véhicules.It will be noted that the header plate is particularly advantageous in that it makes it possible to position a sealing means 17 without requiring openings 4, 18 for the passage of tubes extending over the entire transverse dimension of the plate. which improves the standardization of configurations on vehicles.
