Definitions

  • the invention relates to the field of heat exchangers with welded plates.
  • the invention relates to a plate for a heat exchanger and an associated heat exchanger.
  • the heat exchangers have the function of implementing a heat exchange between several fluids without mixing them.
  • Heat exchangers known as "welded plates” have been democratized for several decades. These exchangers have indeed good thermal performance thanks to their large exchange surface, while being compact.
  • a hot fluid and a cold fluid circulate respectively in the two ducts formed between the plates in two orthogonal directions.
  • each plate comprises a main panel having four sides and four joining panels extending from the sides of the main panel.
  • Each plate further comprises vertical fins extending from each corner of the main panel for securing the plate to the side members.
  • the entire plate package must be connected to the side members, this connection being generally made by welding the fins on the side members.
  • a disadvantage of the heat exchanger is that the fins are fragile and tend to deform under the effect of the pressure exerted by the fluids circulating in the ducts on the plates.
  • connection between the vertical fins and the longitudinal members is subjected to high mechanical stresses due in particular to the thermal expansions experienced by the plates. These stresses can cause breaks in the weld bead at the four corners of the plates, which may jeopardize the tightness of the ducts, or even open a gap between the two ducts.
  • each plate has flat-bottomed bowl shaped bosses formed in the main panel.
  • the bosses of two adjacent plates bear against each other to improve the rigidity of the stack.
  • the stack is welded to gutters covering the longitudinal members.
  • bosses have the effect of reducing the flow section of the fluid flow ducts and the bosses may be fouling zones.
  • each plate has an edge fitting into slots made on corner angles.
  • the interlocking of the plates in the corner angles makes it possible to hold the plates together.
  • the plates are welded to the angles by means of a vertical weld bead extending along the corner angle.
  • a disadvantage of the proposed heat exchanger is that the seal between the fluid circuits and the maintenance of the plates between them are only achieved once the plates are permanently welded to corner angles.
  • One of the aims of the invention is to propose a plate for a heat exchanger which allows the production of a sealed pack of plates and without fluid retention zones, without it being necessary to weld the plate pack on the angle plates. angle, and to be able to assemble a complete pack of plates in a heat exchanger.
  • the stack of plates is self-supporting, that is to say that the plates are held together without it being necessary to connect the plates corner angle.
  • the invention also relates to a heat exchanger plate pack formed by stacking a plurality of plates as defined above.
  • first junction panels and the second junction panels of one of the plates of the stack being respectively connected to second junction panels of a first adjacent plate in the stack to define a first conduit.
  • the invention also relates to a heat exchanger comprising a pack of plates as defined above.
  • the plate 1 for heat exchanger shown is formed in a single piece of material.
  • the plate 1 is formed by deformation of a flat sheet of weldable material, such as for example a steel sheet. This deformation can be obtained by stamping and / or folding, in a pressurized chamber or not. Alternatively, the plate 1 can be made by assembling several independent parts.
