Definitions

  • the applicant has been known such a layer heat exchanger and a method for its preparation.
  • the layer block of the known heat exchanger has separating and cover plates, which are soldered over the entire surface, ie at their contact points. This creates a relatively rigid layer block, which is welded to the housing and / or soldered.
  • a similar layer heat exchanger was by the DE 10 2007 006 615 A1 known.
  • the DE 10 2006 011 508 A1 The applicant was a layer heat exchanger with a layer block of laminated sheets known, which have a bent by 180 ° edge region, which is materially connected to a similar edge region of an adjacent laminated sheet, in particular by soldering using glue strips.
  • the advantage of a Schichthari graduatestragers is provided with a respect to its mechanical properties relatively soft layer block, but still has a high density.
  • the cover and laminations are made of a material that is opposite to the material of the housing has a lower heat resistance, in particular a low hot elastic limit ⁇ 0.2 .
  • a ferritic material can also be selected for the material of the layer and cover plates.
  • the ferritic material in particular an Al-containing material, since this material has a high high temperature corrosion resistance and low Cr evaporation.
  • the wall thickness of the housing is about 1.5 mm and that of the laminations about 0.3 mm.
  • the wall thickness of the housing material can be relatively small relative to the wall thickness of the layer and cover sheet material.
  • the aforementioned measures of different materials for housing and sheets can be supported by structural measures, in particular by the choice of wall thicknesses.
  • a wall thickness of about 1.5 mm and for the sheets a wall thickness of about 0.3 mm is provided for the housing 7.
  • Such a choice of different wall thicknesses would support the above-mentioned choice of different materials or enhance the effect of the invention.
