Definitions

  • the present invention relates to a heat exchanger as defined in the preamble of the single claim and known, for example, from document WO-A-86/05866.
  • Such heat exchangers consist of a stack of plates which are shaped and arranged so as to define, between two reinforcing plates, two separate circuits for the circulation of the heat transfer fluid and the fluid to be heated or cooled.
  • each connector is improved by having at the inner end thereof an axial extension of reduced thickness which, after introduction into the perforation of the end plate is turned over to form a rim similar to the open head of a rivet, the assembly obtained then being passed to the usual brazing operation.
  • each connection a cylindrical end piece which is provided with a thread allowing, after crossing the envisaged reinforcement plate, its screwing in a perforation of one or two end plate (s) (s) of stacking.
  • This nozzle has a groove into which the aforementioned thread opens and which receives the edge of the aforementioned perforation, which groove is then filled with a brazing bead during the brazing operation intended for the sealed assembly of the plates.
  • solder has the sole function of sealing the fastener, the retention in place of each fitting being ensured by screwing the threaded end piece into the terminal plate (s).
  • the exchanger shown is of the conventional type with regard to its general structure, in the sense that it consists of a stack of heat exchange plates 1 held between two reinforcing plates 2 and 3.
  • Each plate 1 is obtained by stamping of a stainless steel sheet, at least one of the faces of which is coated with a layer of solder 1 a ; the stamping tool is profiled so as to determine in each of the plates 1, in addition to a peripheral rim ensuring the guiding of the stack, four depressions or cuvettes (only two of which appear on the drawing) which open in pairs on one or the other of the two faces of the plate considered.
  • the bottom of each bowl is pierced in 1 b and it is understood that if care is taken to reverse the orientation of the successive plates 1 of the stack, there is obtained between the two plates 2 and 3 an assembly defining two independent circuits for the two fluids concerned.
  • One of the plates 2 and 3, namely the upper plate 2 in the example considered, must obviously be equipped with at least four connections for the connection of the two circuits with the installation to which the exchanger must be incorporated.
  • Each of these fittings, referenced 4, is profiled to receive the end of a junction pipe 5.
  • each connector 4 has a cylindrical end piece 4 which has a thread 4b which one end opens out inside an annular groove 4c. It will be observed that the length of each end piece 4 a and the axial positioning of the groove 4 c thereon vary depending on whether the connection 4 envisaged must be associated with a single plate 1 (case of the connection located on the right in the drawing) or to two superposed plates 1, so that in any event each connector 4 communicates well with the end of the circuit to which it corresponds.
  • each connector 4 is first introduced into a perforation 2 a of the upper plate 2, then into the perforation 1 b of the plate or plates 1 envisaged.
  • the diameter of the perforations 1 b is such that by rotation of each fitting, the end piece 4 a is screwed by its thread 4 b into the perforation (s) 1 b which correspond to it, until the edge of the latter come into the groove 4 c (see fig. 2).
