Definitions

  • the invention relates to heat exchangers, especially for motor vehicles.
  • a manifold for heat exchanger comprising a collector plate closed by a wall so as to define a chamber into which at least one manifold opens.
  • a collector box is known from the document EP-A-718580 .
  • the collector plate which is also called a perforated plate, has a plurality of holes in which the tube ends which constitute the heat exchanger bundle are received. To these tubes are associated fins contributing to increase the heat exchange surface.
  • the header plate is closed by a wall so as to define a chamber that communicates with the tubes to allow the circulation of a fluid in the beam.
  • the aforementioned wall is provided with at least one tubing to allow entry or exit of the aforementioned fluid.
  • tubing must be shaped in a particular manner, for example bent, to present a nozzle extending in a given direction to be fitted with a flexible conduit.
  • Collector boxes of this type are already known in which the collector plate is metallic, while the wall is molded of plastic material with the tubing or pipes associated therewith.
  • the seal between the header plate and the wall is provided by means of a seal, the header plate being provided with claws folded or crimped against a peripheral rim of the wall.
  • Collector boxes of this type are also known in which the various elements are metal parts assembled together by brazing.
  • the object of the invention is in particular to overcome the aforementioned drawbacks.
  • the constituent elements of the header can be brazed in an oven, along with the rest of the heat exchanger, which significantly simplifies the manufacturing operations.
  • the two lateral flanks of the first part are generally planar and parallel to each other and are connected perpendicular to the bottom.
  • the two lateral flanks of the first part each comprise a peripheral groove for receiving a longitudinal edge of the second part. This contributes to a good temporary maintenance of the first part and the second part between them.
  • this temporary support can be provided by the fact that the two lateral flanks of the first part each comprise a series of cutouts delimiting bearing regions formed projecting from the inner side for receiving a longitudinal edge of the second part. .
  • these bearing regions are each formed by stamping the side flanks of the inner side.
  • each longitudinal edge of the second part is provided with protruding lugs adapted to engage respectively in the cuts of the lateral flanks.
  • the second lid part is defined by a strip shaped to have generatrices generally parallel to each other.
  • the two side flanks advantageously have respective extensions vis-à-vis, at least one of which is provided with an opening for the tubing.
  • the first part and the second part are each obtained by stamping and cutting a metal sheet.
  • the latter is advantageously a sheet made of a material comprising aluminum.
  • the invention in another aspect, relates to a heat exchanger comprising at least one manifold as defined above.
  • the manifold comprises a first portion 10 and a second portion 12 each formed from a metal sheet, preferably aluminum, which is shaped by conventional cutting and stamping operations.
  • the first part 10 has a bottom 14 which is generally flat and of elongated rectangular shape.
  • This bottom 14 is intended to form the collector plate, also called “plate with holes", of the manifold.
  • This bottom comprises for this purpose a plurality of spaced holes 16 of elongated shape intended to receive tubes 18 forming part of a bundle of a heat exchanger ( Figures 1 and 2 ).
  • these are flat tubes between which fins 20 are arranged in the form of corrugated inserts.
  • the sheet further comprises two lateral flanks 22 folded vis-à-vis, which are generally planar and parallel to each other. These flanks are connected substantially perpendicular to the bottom 14 by two fold lines 24 which are parallel to each other.
  • the lateral flanks 22 are of elongate shape and comprise, in their central part, respective extensions 26 and 28 arranged in facing relation and each having a "cocked hat" shape.
  • the extension 26 has an opening 30, while the extension 28 is completely closed.
  • the opening 30 is circular in shape and is intended to allow the adaptation of a tubular 32 of circular section.
  • the two lateral flanks 22 of the first portion 10 each comprise a peripheral groove 34 for receiving a longitudinal edge 38 of the second portion 12. This contributes to a good temporary retention of the first part and the second part between them.
  • the second portion 12 forming a lid is defined by a strip shaped to have generatrices generally parallel to each other.
  • the constituent elements of the header can be brazed in an oven, along with the rest of the heat exchanger, which significantly simplifies the manufacturing operations.
  • the header plate is included in the second part 52, while the bottom 54 of the first part 50 is closed and is connected to the lateral flanks 56.
  • the two parts can be achieved by conventional operations of cutting and stamping a metal sheet.
  • the temporary maintenance is provided in that the two lateral flanks 78 of the first part 72 each comprise a series of cutouts 86 delimiting bearing regions 88 formed projecting from the inner side for the reception of a longitudinal edge 90 of the second portion 74. These bearing regions 88 are each formed by stamping the side flanks 78 on the inner side.
  • Each longitudinal edge 90 of the second portion 74 is provided with lugs 92 projecting to engage respectively in the cutouts 86 of the lateral flanks 78 ( Figures 15 to 17 ).
  • the two parts can be made by conventional cutting and stamping operations.
  • the assembly After assembly of the two parts and the tubing, the assembly can be brazed in an oven, along with the rest of the heat exchanger to be manufactured.
  • the invention finds particular application to heat exchangers for motor vehicles to constitute for example a cooling radiator of the engine, or a heating radiator of the passenger compartment.
