Definitions

  • the invention relates to a heat exchanger, according to the preamble of claim 1.
  • Such Heat exchanger is known from EP-A1-0 593 360.

  • Any fluid box is made up of at least two shell elements, which are tightly joined in a longitudinal plane of the fins / tube block are.
  • these shell elements are made from only two shell elements preferably constructed as half shells. Because the Shell elements in a longitudinal plane of the fins / tube block are assembled, each shell element only needs to be about have half the depth of the entire fluid box, so that the shell elements even with more complex designs streamlined shapes through a deep-drawing process can be produced.
  • the shell elements are preferably either mechanically by clawing, riveting or torken or connected by spot welding. Appropriate solder coatings are used Shell elements then in the area of their joints by brazing tightly connected.
  • each fluid box from at least two shell elements in particular of two half shells, which are in a longitudinal plane of the Ribs / tube block are separated from each other, thus allowed due to the comparatively low drawing depth of each shell element a fluidic adaptation to the respective Strömungsstoff befluß.

  • both half-shells have one each running along their joining edges Joining flange on, in the assembled state of the half shells are interconnected. Through the joining flanges the rigidity of each fluid box is increased because the joining flanges in the assembled state of the half-shell elements have the function of a stiffening rib.
