ABSTRACT:
Heating device with a heating element of a material with positive temperature coefficient, of which two opposite sides are contacted by planar electrodes and give off the heat produced through the electrodes and planar sheets of insulating material covering the same to two heat-absorbing surfaces of a heater. The sheets of insulating material are coated on their side facing the heating element over a large area with a solder and are soldered to the electrodes. This insures permanent good heat transfer between the electrodes and the insulating material covering them. The firmly joining together of the heating element and the sheets of insulating material to form a structural unit facilitates the assembly, i.e., the installation of the heating device.
