ABSTRACT:
A heat-generating element of a heating device for heating air including at least one PTC element, electric strip conductors lying on the PTC elements and a longish positioning frame that forms at least one frame opening for holding the minimum of one PTC element. A heat-generating element that is improved with a view to safety from electric flashovers and leakage currents is created with the invention under consideration by providing at least one insulating layer, which covers the strip conductor on its exterior side that is turned away from the positioning frame. The insulating layer in any case is sealed against the long sides of the positioning frame by a compressible sealing bead. A heating device for heating air with multiple heat-generating elements is also disclosed.
