Definitions

  • the invention relates to heat exchangers of the type comprising at least one fluid box with a tubular wall, separated into compartments by a transverse partition, and a multiplicity of parallel tubes, each communicating with a compartment of the fluid box by an opening of said tubular wall.
  • FR-A-2 676 535 which is considered to be the closest state of the art, proposes to introduce the partition into the tubular wall, through an open end thereof, for the bring it into the position it must occupy, then deform the tubular wall on either side of the partition to immobilize it.
  • the invention provides an even simpler solution, particularly suited to the case where the fluid box comprises a single transverse partition.
  • the invention relates to a method for producing a heat exchanger comprising at least one fluid box with a tubular wall, separated into compartments by a transverse partition substantially in the form of a disc, and a multiplicity of parallel tubes, each communicating with a compartment. of the fluid box by an opening of said tubular wall, process in which the partition is introduced into the tubular wall, by an open end of the latter, to bring it into the position which it must occupy.
  • the partition is then deformed by means of tools applied against the two faces of the latter, by expanding it radially so as to immobilize it in said position by clamping in the tubular wall.
  • FIGS. 1 and 2 are views in axial section showing two successive phases of the method according to the invention .
  • the figures show a tubular wall 1 intended for a heat exchanger fluid box, in particular a condenser for an air conditioning installation of the passenger compartment of a motor vehicle, and a transverse partition 2 in the form of a disc intended to separate the interior volume of the fluid box in two compartments 3 and 4.
  • the completed heat exchanger comprises a series of fluid circulation tubes, not shown, oriented perpendicular to the longitudinal axis 5 of the tubular wall and mutually aligned along the latter, the ends of which pass through openings made in the tubular wall, and which open one into compartment 3, the other into compartment 4.
  • the partition 2 In its initial state, as shown in FIG. 1, the partition 2 has opposite faces 6 and 7 which are flat and parallel, and has a diameter slightly less than the inside diameter of the tubular wall 1. It can therefore be inserted therein with play, by one of the open ends thereof, to be brought to the desired location.
  • Two punches 8 and 9 are also introduced with play in the tubular wall, on either side of the partition.
  • the end face of each punch facing the partition, or working face has an annular rib 10 of revolution around axis 5, limited by two frustoconical surfaces, one radially exterior 11, the other radially interior 12, defining between them a circular edge 13.
  • the generatrix of surface 11 forms an angle with axis 5 greater than 45 °, and that of the surface 12 an angle less than 45 °.
  • the annular surface 12 delimits in the working face of the punch a central recess having a flat bottom 16.
  • the working faces of the punches may have a shape different from that described and shown.
  • the recess defined by the frustoconical surfaces 12 and the flat bottom 16 can be eliminated and replaced by a flat surface limited by the circular edge 13.
