Definitions

  • the present invention relates to the technical field of motor vehicle equipment, in particular air supply equipment for motor vehicle engines and more particularly to engines whose supply air comes from a compressor or a turbocharger.
  • Charge air Supply air from a supercharger or turbocharger is also called “charge air”.
  • RAS charge air cooler
  • a RAS usually has a swap beam.
  • This exchange bundle comprises a stack of plates or tubes alternately forming circulation channels for the supercharged air to be cooled and channels for the circulation of heat transfer fluid, in particular engine coolant.
  • the heat exchange between the plates or tubes and the supercharging air is carried out partly by means of turbulators.
  • the beam is enclosed in a receptacle or casing which generally has the shape of a straight and hollow cylinder, most often with a rectangular base, connected at one of its open ends to an inlet manifold and to the the other to an outlet collector box (I-shaped configuration, that is to say that the air to be cooled follows a straight line path); or at one of its ends open to an inlet and outlet manifold and at the other to a deflection manifold (U-shaped configuration, i.e. the air to be cooled follows an angled path in order to come out substantially collinearly with its entry direction).
  • I-shaped configuration that is to say that the air to be cooled follows a straight line path
  • U-shaped configuration i.e. the air to be cooled follows an angled path in order to come out substantially collinearly with its entry direction
  • the casing is generally formed of four aluminum parts each forming one of the sides of the hollow cylinder, forming at the open ends of the latter end edges.
  • These aluminum parts usually have a flattened shape, giving them the shape of plates. Some of the plates may present on two of their sides outgoing flanges.
  • these four parts are provided with teeth or staples to produce a mechanical connection, in particular on the outgoing flanges.
  • a collection flange is arranged at each of the open end edges of the hollow cylinder formed by the casing to ensure the connection with the corresponding manifold.
  • These collection flanges have the shape of a band whose size and geometry correspond to that of the end edges of the casing.
  • the headband has square corners that the corner of the end edges of the casing cannot entirely fill, so that between the casing and the collection flange, there are holes which cannot be sealed during brazing.
  • these holes are responsible for air leaks resulting in pressure losses synonymous with loss of performance.
  • a heat exchanger according to the preamble of claim 1 is known from document GB 2 507 495 A .
  • an objective of the present invention is to overcome at least one of the drawbacks of the prior art described above, and in particular to improve the efficiency of the heat exchanger.
  • the outer surface of the hollow cylinder at the corners of the coupling edge is continuous with a smooth transition between two adjacent faces eliminating the triple points responsible for pressure loss.
  • the housing can be made in four housing parts.
  • the housing may comprise two I-housing parts and two C-housing parts.
  • the heat exchanger may further comprise means for holding the housing parts before brazing.
  • two adjacent housing parts each comprising a connection edge for connection to one another, the connection edges being of complementary shape
  • the holding means may comprise a male part on the connection edge of one of the two housing parts and a female part on the connecting edge of the other of the two housing parts.
  • Such holding means are self-locking allowing manipulation of the casing after assembly and before brazing.
  • the male part can be a barricade and the female part a slot.
  • the male part can be the counterpunch of a capital omega
  • the female part a complementary shape
  • a connection edge can comprise one or more male parts and one or more female parts.
  • the shape of each of the male parts can be chosen independently of the others between a merlon and the counterpunch of a capital omega
  • the shape of each of the female parts can be chosen independently of the others between a slot and the shape complementary to the counterpunch of a capital omega.
  • the means retainers may comprise a U-shaped retainer partially covering each of the two housing parts, including a portion of their connecting edges, preferably in the central portions of the connecting edges. Thanks to the U-shaped holding piece, the assembly obtained of the various casing parts in them is robust and stable before the brazing thereof. Furthermore, it reinforces the brazed connection between the various parts of the casing by playing the role of sheathing material, all the more avoiding the formation of holes conducive to air ducts. Finally, it allows further reinforcement of the mechanical strength of the casing by increasing it where the stresses are maximum.
  • the casing can be made in four casing parts comprising two opposed I-shaped casing parts and two opposed C-shaped casing parts, preferably the I-shaped casing parts are smaller than the two C-shaped casing parts.
  • one of the I-shaped casing parts can be a collector plate and the U-shaped retaining part can be a collector box.
  • the collector box can be an air box or a water box.
  • a heat exchanger 1 according to the invention is described below with reference to the figures 1 to 5 .

  • the bundle casing 3 is made of at least two casing parts 34a-34d and substantially defines a hollow parallelepiped whose one face is open (open face 31) so that the four adjacent faces 32a-32d form an end edge bordered on the outer surface of the casing by a coupling edge 33 belonging to the latter.
  • This outer surface is typically made up of the faces of the housing parts 34a-34d and not the edges thereof.
  • the terms “casing parts” designate in the context of this presentation parts which have been assembled and then fixed to each other to form the harness casing 3. Thus, they are not made in one piece with the other.
  • the beam housing 3 may also have another open face 31 opposite this first open face 31 so that the four adjacent faces 32a-32d form another end edge also bordered on the outer surface of the housing another coupling edge 33.
  • the rest of the description will only mention an open face and a coupling border, but what is described for an open face and a coupling border is valid for the other opposite open face and the other coupling edge.
  • the harness casing 3 has a longitudinal axis which is parallel to the four adjacent faces 32a-32d.
  • the coupling edge 33 has rounded corners 331 (for example in an arc of a circle with a radius of between 1.5 and 8 mm), and the housing parts 34a-34d are arranged so that at the level of the edge coupling 33, the outer surface of one substantially extends the outer surface of the other: in other words, at the level of the connection between two housing parts 34a, 34b ; 34b, 34c ; 34c, 34d ; 34d, 34a, the surfaces of the two parts are at the same level.
