Definitions

  • the invention relates to an exchanger. Although more particularly intended for applications as an internal exchanger of an air conditioning loop or exchanger between a refrigerant and a coolant, it will be more widely used for any type of heat exchange between two fluids.
  • Such a configuration multiplies the soldering zones, in particular at the junction between the connecting elements and the through holes of neighboring plates. It also multiplies the risks in terms of sealing between each of the fluid circuits. Specific sealing tests are thus necessary.
  • the zones of the plates provided with said connecting elements contribute little or no to the heat exchange. They therefore increase the cost of the exchanger by the mass of material engaged without improving the efficiency of the heat exchange.
  • a heat exchanger according to the preamble of claim 1 is known from the document FR 2 728 666 A .
