  • Said fold may be a lateral junction flange of the collector to the housing, for example said flange forming with the housing a lateral cavity arranged for maintaining in position a part, in particular the corner or corners, of each of the plates of the heat exchange bundle in the housing.
  • said lateral junction flange of the collector is configured to cooperate with a lateral flange connecting the housing to the collector, preferably along a flat junction surface which promotes a solder connection.
  • said flanges of the collector and the housing are offset relative to each other so as to define a positioning shoulder of said beam to form said lateral cavity arranged to hold a part in position, in particular the corner or corners , of each of the plates of the heat exchange bundle in the housing.
  • the depth of said rim of the collector is greater than that of said rim of the housing.
  • the difference in depth of said flanges is in particular said shoulder for holding in position the corner or corners of the plates of the heat exchanger.
  • the plates of the heat exchange bundle are identical to one another, for example of rectangular format, and their stack delimits a parallelepiped, in particular rectangle.
  • the heat exchanger may comprise a said manifold forming inlet manifold of the heat exchanger and another said collector forming an outlet manifold of the heat exchanger.
  • said collectors are opposed to one another relative to a median plane of the heat exchange bundle.
  • said collectors together comprise four deformations of each of the collectors, able to hold in position each a corner of the heat exchange bundle in the housing.
  • the inlet manifold and / or the outlet manifold are configured to be connected, for example, to a conduit or hose for circulating the first fluid.
  • the exchanger can still form an air intake module in which the outlet manifold is an air distributor, configured to be attached to an engine cylinder head, so as to distribute air to intake pipes. a motor cylinder head.
  • Said exchanger is, for example, aluminum and / or aluminum alloy.
  • the collector can be brazed to said casing in a single operation, this brazing being advantageous when brazing in a single operation or a single blow, of the heat exchanger, said exchanger being previously assembled so that said beam is positioned in said housing by said collector (s) using said positioning stop. It may further be considered that the invention also relates to such a method of manufacturing a heat exchanger.
  • the invention relates to a heat exchanger 1, in particular for a motor vehicle, comprising a heat exchange bundle 3 between a first fluid A (according to arrow) and a second fluid L (according to arrow), and a casing 5 to inside which said beam 3 is housed.
  • Said heat exchanger 1 further comprises at least one manifold 7 secured to said casing 5, for example an air intake manifold 7 fixed to said casing as illustrated in this case and an air outlet manifold (not shown) which may be symmetrical input manifold 7 with respect to a median plane P of the beam 3 or the heat exchanger.
  • Said exchanger is made, for example, of aluminum and / or aluminum alloy.
  • Said first fluid A may be charge air of the vehicle engine.
  • Said second fluid L may be a cooling liquid.
  • the casing 5 here has two parallel upper faces 11 and 13, substantially rectangular, provided with an extension 11a, 13a substantially trapezoidal.
  • the extensions 11a and 13a of these upper and lower faces beyond the section or projection of the bundle 3 constitute the upper and lower faces, respectively, of the collector 7.
  • the casing further comprises two rectangular lateral walls 15, opposite one another, connecting said upper 11 and lower 13 faces. It should be noted that one of them may alternatively (not shown) a collector plate of the beam connected to two side manifolds, respectively inlet and outlet of the second fluid.
  • the casing thus has two open faces 17 opposite each other and called first and second free faces 17.
  • the inlet manifold 7 of the first fluid is connected to the first free face 17 of the housing by an edge 17a of said housing, here said extensions 11a and 13a of said upper faces 11 and lower 13, applied against a corresponding flat flange 18 of a cover 30 of the collector.
  • the housing 5 is connected to the outlet manifold (not shown) at its second free face.
  • the first fluid A passes through the heat exchange bundle 3, guided by the casing 5, right through from the inlet manifold 7 to the outlet manifold, entering and leaving the exchanger by means of tubing 19 connection to conduits or fluid circulation hoses, through respective inlet and outlet ports 21.
  • Each of the walls 11, 13, 15 of the casing here consists of a plate, said plates being secured to each other by their edge, in particular by brazing, to form said casing.
  • Circuits for the circulation of the first fluid A are provided in the heat exchange bundle 3, through disrupters 32, only the disrupters of an upper and lower part of the beam having been represented. More specifically, the beam 3 is formed in the example of parallel plates 23, stacked in a stacking direction D, said plates allowing the circulation of the first and second fluid A, L so as to ensure a heat exchange between said fluids.
  • the plates 23 are grouped in pairs and together define a circulation circuit of the second fluid L.
  • An upper plate and a lower plate of a the same pair of plates 23 complement each other to constitute a circulation duct of the second fluid L.
  • the plates 23 of the same pair comprise two facing bosses (not shown) for passing the second fluid L into the duct formed by said pair of plates, said bosses of a pair of plates being connected to the bosses of neighboring pairs of plates.

  • the circulation circuits of the first fluid A are defined by the plates 23 of two pairs of adjacent plates.
  • the plates 23 here have the general shape of an elongated rectangle of just shorter length than that of the upper and lower faces 11, 13 of the casing and of width equal to that of the side faces 15 of the casing (see also FIG. figure 2 ).
  • the stack of plates 23 forms a rectangular parallelepiped.
  • each of the covers 30 of the manifolds 7 has a side wall 29 connected to the side walls 15 of the housing according to a side flange 29a of the wall 29 of the manifold joining a flange 15a of the wall 15 of the housing.

  • the assembly of the collector on the housing positions the beam in said housing.
  • such positioning takes place, before soldering the parts together. It aims to ensure the quality of brazing by ensuring a prior positioning of parts.
  • such an assembly takes place before passage of the exchanger in a brazing furnace.
  • Such an assembly before brazing can be obtained by crimping the walls 29, 15 of the collector and the housing, here, using teeth 34 of the housing cooperating with clips 36 of the collector ( figure 1 ).
  • the plates 23 are stacked accurately with respect to the casing (transversely to the vertical stacking direction of the plates, in vertical alignment) so as to be held horizontally in the casing while allowing a vertical freedom of movement connecting the plates to one another soldering.
  • the stop formed by the invention does not impinge or very little on the passage surface of the first fluid through the beam. In this way, it is avoided to disturb the flow of said first fluid and to reduce the heat exchange surfaces.
  • this design of the collector formed with casing wall extensions and a single cover 30 facilitates the drawing of said cover 30 by allowing, in a single forming operation to obtain both said beam positioning deformations in the casing as well as the solder joint flanges to the casing.
  • the heat exchanger may also form an air intake module in which the outlet manifold is an air distributor, configured to be attached to an engine cylinder head so as to distribute the air to breech intake pipes.
  • the first fluid then flows through the inlet manifold, the exchanger and the air distributor.
