  • the set of plates 18 comprises a plurality of identical plates 4.
  • the plate set 18 comprises a number of plates 4 which varies according to the model of heat exchanger considered.
  • X4 is a central axis of the game 18 and each plate 4 which is perpendicular to the main surfaces 40 of the plates. In assembled configuration, the axis X4 of the plates 4 is superimposed on the axis X1 of the exchanger 1.
  • the plates 4 are arranged in the game 18 in configuration head to tail, as visible on the Figures 4 to 6 . In other words, each plate 4 is rotated 180 ° about the axis X4 relative to the plate (s) 4 adjacent (s).
  • Each plate 4 of the plate set 18 is of generally rectangular shape.
  • each plate 4 has two main surfaces 40A and 40B, two longitudinal edges 41 and two transverse edges 42 surrounding the surfaces 40.
  • the surfaces 40A of the plates 4 are visible at figures 2 and 6 , while the surfaces 40B are masked there.
  • Each plate 4 also has four rounded corners 43. In the vicinity of each rounded corner 43, the plate 4 is provided with a bore 44 configured to receive the pipe pipe 14.
  • the bores 44 have corrugations.
  • the plate 4 On each short edge 42, the plate 4 has a notch 45 intended to support one of the two guide bars 12.
  • the main surfaces 40A and 40B of the plate 4 are provided with ribs 46.
  • the ribs 46 are formed according to a particular profile, for example a chevron profile, and are intended to define the heat transfer fluid circulation channels. In a manner known per se, the channels determine a turbulent flow of such fluid.
  • the longitudinal edges 41 and the transverse edges 42 have, over their entire length and except the housing 45, corrugations 47 each defining a bottom 48 plane.
  • the bottom 48 of some corrugations 47 is provided with a recess 50 which forms a recessed housing seen from the side of the surface 40A.
  • a wave 47A whose bottom 48 is provided with a housing 50.

  • the plate 4 has along its longitudinal edges 41 eight pairs 54, that is to say four pairs 54 on each edge 41.
  • the reliefs 50 and 52 which are complementary because the outer shape of the rib 52 is adjusted to the inner shape of the recess 50, are made by localized stamping of the edges 41, with a longitudinal direction parallel to the edge 41 on which they are spared.
  • the pairs 54 of reliefs 50 and 52 are formed on the longitudinal edges 41 with central symmetry with respect to the axis X4.
  • the hollow recesses 50 and the protruding members 52 have a semicircular section, as can be seen in FIG. figure 7 .
  • the hollow recesses 50 and the projecting members 52 have a V-section.
  • the cross-section of the hollow recesses 50 and protruding members 52 has another shape which also allows locking in the direction D1.
  • the housings 50 and the members 52 have a section that results from a combination between a semicircle and a V.
  • edges 41 and 42 define polygonal, hexagon-shaped figures 56 staggered along the edges 41 and 42. This offset is due to the head-to-tail configuration with which the plates 4 are arranged.
  • the protruding members 52 of each plate are received in corresponding recessed recesses 50 of the adjacent plate 4.
  • the recessed housing 50 of the central plate 4 accommodates a protruding member 52 of the second plate 4, when the protruding member 52 of the central plate 4 is arranged in a recessed housing 50 of the third plate 4.
  • the pair of reliefs 54 of the central plate defines a recess with corresponding relief pairs 54 of the second and third plates 4.
  • the pair of reliefs 54 of the central plate defines a recess with corresponding relief pairs 54 of the second and third plates 4.
  • between two adjacent plates 4 are present eight recesses.
  • Recesses allow the plates 4 of the game 18 to remain aligned during assembly. Indeed, insofar as the projecting members 52 are locked in the hollow recesses 50 in a direction perpendicular to the edges 41 and the axis X4, and therefore perpendicular to the edges 42, a relative displacement between two or more plates 4 according to this direction is prevented.
  • the ribs 46 of two surfaces 40 of two adjacent plates 4 define the circulation channels of the coolant.
  • the transverse edges 42 of the plates 4 are also provided with pairs 54 of reliefs 50 and 52.
  • the manufacturing process of the plate 4 comprises a step a) of making the ribs 46 on the main surfaces 40 of the plate 4.
  • the method also comprises a step b) of producing the corrugations 47 on the edges 41 and 42 of the plate 4, and finally a step c) of producing the hollow recesses 50 and projecting members 52 on the edges 41 and 42 of the plate 4, at the corrugations 47A and 47B. Steps a) to c) are performed at the same time.
