Definitions

  • the invention relates to the field of heat exchangers, in particular for motor vehicles.
  • 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.
  • 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.
  • 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.
  • a peripheral groove is not always present continuously on the periphery of the header plate.
  • the heat tubes may vary in size depending on the vehicle, so that the collector plates have varying configurations.
  • 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.
  • the present invention is intended to provide a header plate for positioning a seal even with tubes of dimension smaller than the lid.
  • 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 pro
  • 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.
  • 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.
  • the local protuberance is distinguished from a continuous peripheral groove.
  • 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.
  • 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.
  • the sealing means is generally a seal having a closed contour, intended to seal the junction cover / collector plate, especially airtightness.
  • the local protuberance thus makes it possible to compensate for the reduction in size of the tube used.
  • the prominent part is a central flat part that emerges from the throat, it is usually embossed, it can be called "medallion".
  • the recessed portion has the advantage of facilitating the stamping of the collector plate.
  • 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.
  • this recessed portion facilitates the assembly of the sealing means on the header plate.
  • 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.
  • a collector plate 2 for a collector box of a 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the manifold plate 2 comprises a local protrusion 20 for positioning the sealing means 17.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the collector plate 2 is assembled to the cover 25 in the following manner, with reference to the figure 3 .
  • the sealing means 17 are reported inside the receiving housing composed mainly of the grooves 16 and the parts 22, 24.
  • 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.
  • the lid 25 is reported by pressing its edge 26 in the reception housing 16, 22, 24, above the sealing means 17.
  • 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.
  • 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.
  • 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.
  • the header plate comprises a local protuberance 20 at each of its corners.
  • 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
  • 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.
