  • the present invention seeks to provide the best possible corresponding electrical heating devices for these conflicting requirements.
  • the window accordingly forms an opening between the interior of the Schurippenrahmens, which serves to receive the PTC heating element, and the outer surface, which is usually flowed by the medium to be heated.
  • the invention lies in this window the insulating layer free, so that the heat generated by the PTC element must be passed through only through the conductor track and through the insulating layer before this heat can be removed by convection on the surface of the electrical insulating layer.
  • the planteleitwege are shortened accordingly.
  • the electrical performance of the PTC element can be used in the best possible way.
