Definitions

  • the invention relates to heat exchangers according to the preamble of claim 1, in particular for motor vehicles.
  • Heat exchangers of this type usually comprise a bundle of tubes and vanes of which at least one end is connected to a header to allow the circulation of a first fluid which exchanges heat with a second fluid sweeping the beam of the heat exchanger.
  • Such a heat exchanger may constitute, for example, an engine cooling radiator or a heating radiator of the passenger compartment.
  • the heat exchanger is usually traversed by the engine coolant.
  • the heat exchanger can also constitute an evaporator or a condenser of an air conditioning circuit.
  • the fluid flowing through the heat exchanger is a coolant.
  • Heat exchangers are also known, known as “plate heat exchangers", which comprise a multiplicity of stacked plates, arranged in pairs facing each other, and arranged to define a multiplicity of chambers for the circulation of heat exchangers. a first fluid, this fluid exchanging heat with a second fluid flowing outside the plates.
  • Heat-exchanging corrugated inserts are also usually provided which are each placed between a plate of one pair and a plate of another adjacent pair.
  • plate heat exchangers are rather used in air conditioning circuits, for example as evaporators, or for cooling an oil, in particular the engine lubricating oil, the gearbox oil, etc.
  • the invention proposes for this purpose a heat exchanger according to claim 1.
  • the first fluid flows countercurrently with respect to the second fluid that circulates outside the plates. This results in a better heat exchange compared to known heat exchangers, whether they are tube bundle heat exchangers or plate heat exchangers.
  • the inlet and the outlet of a plate are formed by openings arranged in the plane of the plate and are each bordered by a collar to allow connection to the inlet and the outlet of an adjacent plate forming part of the plate. an adjacent room.
  • the first fluid feeds the respective inputs of the plates, circulates in the chambers against the current and leaves the plates by their respective outlets.
  • each plate comprises deflectors formed projecting from the lower side of the plate which faces the chamber, to promote the flow of the first fluid against the current.
  • the baffles can be made in different ways.
  • These deflectors may comprise generally straight deflectors favoring a direct flow against the current of the first fluid from the inlet to the outlet.
  • They may also comprise deflectors favoring a U-shaped flow of the first fluid with a first path extending from the entrance and extending in a transverse direction, a second counter-current path and a third path extending in the transverse direction and leading to to the output.
  • the first and third paths the first fluid flows in the transverse direction, that is to say in a direction generally perpendicular to the flow of the second fluid, which does not affect the heat transfer.

  • the manifold is arranged to include an elongated input compartment which communicates with the main entrance and with both entrances the end plate, and an elongate outlet compartment that communicates with the main outlet and with both end plate outlets.

Each of the pairs defines a chamber for the circulation of a first fluid that circulates in each of the plates in generally parallel directions from left to right (in the figure), as shown by the arrows F1.
