Definitions

  • the invention relates to heat exchangers of the type comprising at least one fluid box with tubular walls, separated into compartments by at least one transverse partition, and a multiplicity of parallel tubes, each communicating with a compartment of the fluid box by a opening of said tubular wall.
  • the object of the invention is to remedy these drawbacks.
  • the invention relates to a method for producing a heat exchanger as defined in the introduction, in which each partition is introduced into the tubular wall, by an open end thereof, to bring it to the place that it must occupy, and the tubular wall is deformed on either side of the partition to immobilize the latter.
  • the ends of the tubular wall can in particular be closed by additional transverse partitions which are also immobilized by deformation of the tubular wall.
  • the tubular wall is brazed to the partition and / or to the tubes in a sealed manner to the fluid which must circulate in the exchanger, this brazing being able in particular to be carried out by melting a fusible metal coating provided on at least one of the parts to be brazed.
  • the tubular wall has, before deformation, an irregular internal profile surrounding the partition at a distance over a substantial fraction of its perimeter
  • the tubular wall is formed by a rolled sheet whose opposite edges are linked, in particular welded, according to a generatrix of the wall, by forming a bead inwards.
  • the invention also relates to a heat exchanger as can be obtained by the process defined above, comprising at least one fluid box separated into compartments by at least one transverse partition, and a multiplicity of parallel tubes, communicating each with a compartment of the fluid box through an opening thereof, the fluid box comprising a tubular wall pierced by said openings and surrounding the edge of the partition, and deformed on either side thereof for immobilize it.
  • the illustrated heat exchanger intended in particular to serve as a condenser in an air conditioning installation of the passenger compartment of a motor vehicle, comprises a fluid box 1 formed by a tubular wall 2 having a multiplicity of openings 3 in each which engages a tube 4 whose cross section is elongated in the transverse direction of the fluid box, the tubes 4 being mutually parallel and perpendicular to the longitudinal direction of the fluid box.
  • One end 5 of each of the tubes 4 is located inside the fluid box 1, the opposite end may be inside another fluid box not shown, similar to the fluid box 1 and extending parallel to it.
  • Dividers 6 constituted by strips of metal sheet curved in the form of a sinusoid are placed in the gaps between the tubes 4 to come into thermal contact with them.
  • tubular wall 2 is pressed towards the inside of the fluid box around the openings 3, forming craters 7 facing outwards.
  • partitions extend transversely inside the fluid box, namely two end partitions 8a and 8b (collectively designated by the reference 8) cooperating with the tubular wall 2 to delimit the interior space of the fluid box, and intermediate partitions 9a, 9b (collectively designated by the reference 9) dividing this interior space into different compartments 10a, 10b, 10c, 10d (the references 10b and 10c correspond to two different compartments or to the same compartment according to whether or not there is at least one other partition, not shown, between the partitions 9a and 9b).
  • Each of the partitions 8 and 9 is immobilized in its place by deformations 11 of the tubular wall 2.
  • these deformations 11 are moldings projecting towards the inside of the fluid box, extending circumferentially from continuously. Two moldings 11 are provided for each partition, placed on either side thereof in the longitudinal direction of the fluid box. These moldings can be replaced by deformations of another type, which can be discontinuous in the circumferential direction.
  • the peripheral edge of the partitions 8 and 9 is tightly brazed to the internal surface of the tubular wall 2, and the external surface of the tubes 4 is tightly brazed to the edges of the openings 3.
  • a tubular wall 2 of cylindrical shape having a uniform internal cross section which is substantially circular and sufficiently large to allow the longitudinal sliding of the partitions 8 and 9, the outline of which is also circular.
  • Each of the partitions is introduced through one of the open ends of the tubular wall and it is made to slide longitudinally to the place it is to occupy.
  • the deformations can be obtained by any known means (jaws, knurls, etc.).
  • the tubular wall 2 is frequently constituted by a rolled and assembled sheet, in particular welded, edge to edge by forming a bead projecting inwards.
  • the partitions can then enter the tubular wall only if the internal diameter of the latter is at least equal to that of the partitions increased by the thickness of the bead, so that an appreciable gap exists between the peripheral edge of the partitions and the internal surface of the tubular wall, over most of the perimeter. It is therefore advantageous that the deformation of the latter is sufficient to eliminate this interval, facilitating the subsequent tight brazing of the edge of the partitions.
  • the seal between the outer surface of the tubes 4 and the openings 3 on the one hand, between the edge of the partitions 8 and 9 and the inner surface of the tubular wall 2 on the other hand, is obtained by brazing by means of a fusible metal coating which is melted by heating the assembled heat exchanger.
  • This coating is preferably provided on the outer surface of the tubular wall 2 for its connection with the tubes, and on the partitions for their connection with the tubular wall. This prevents the presence of such a coating on the internal surface of the tubular wall, which could cause partial closure of the ends of the tubes.
