Definitions

  • the present invention relates to heat exchangers constituted by 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 coolant and the fluid to be heated or cooled.
  • the invention mainly consists in making the end piece of each fitting have a thread which opens out inside an annular groove capable of forming a housing for the edge of the perforation formed in the end plate or plates for receiving said end piece, the thin annular space which remains at the end of screwing at the bottom of the aforementioned groove being closed in leaktight manner by the assembly braze.
  • soldering has the sole function of sealing the fixing, the retention in place of each fitting being ensured by screwing the threaded end piece into the terminal plate (s).
  • Fig. 1 is a vertical section showing the general arrangement of the elements which constitute a heat exchanger established in accordance with the invention.
  • Fig. 2 reproduced fig. 1 after fitting the fittings by screwing.
  • Fig. 3 shows in the same way the exchanger obtained after brazing the assembly.
  • 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 or perforations 1 b which correspond to it, until the edge of the latter come into the groove 4 c (see fig. 2).
