Definitions

  • the invention relates to a heat exchanger in the preamble of claim 1 specified genus.
  • Heat exchangers of this type are known in numerous embodiments. You serve when used on tumble dryers, the purpose of drying room to guide incoming, moist process air through process air channels and at the same time to cool with ambient or room air flowing through cooling air ducts.
  • the Heat exchangers act as condensers for the process air, and from this condensing water drips into a collecting vessel. The process air thus dried is returned to the drying room after heating.
  • the process air and cooling air channels are usually perpendicular to each other, so that the heat exchanger in cross flow is flowed through by the process air and the cooling air.
  • Heat exchangers made entirely of metal of the type described at the beginning work perfectly with regard to the desired heat exchange.
