Definitions

  • the invention relates to a heat exchanger according to claim 1 and a heater according to claim 11.
  • Generic heat exchangers are well known from a variety of applications from various engineering fields. They serve, among other things, the cooling of a stream and the heating and cooling of another stream. These streams may be liquid, vapor or gaseous and are also called fluids due to their flowable state of aggregation. The streams or fluids do not come into direct contact with each other, but they flow in each case associated flow spaces and transmit their thermal energy through a heat-permeable wall separating the flow spaces. This form of heat transfer is called "indirect" because of the separation of the streams.
