Abstract
A heat-generating element of a heating device for heating air includes at least one PTC element and, lying on opposing side surfaces of the PTC element, electric strip conductors. 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 an insulating gap between the PTC element and the positioning frame material that circumferentially surrounds the frame opening. Also disclosed is a heating device for heating air with multiple heat-generating elements, each heat-generating element comprising at least one PTC element and, lying on opposing side surfaces of the PTC element, electric strip conductors and multiple heat-emitting elements that are arranged in parallel layers and that are held in position in a frame on opposing sides of the heat-generating element with a spring bias. Due to the use of a heat-generating element, the heating device is protected from electric flashovers and leakage currents with a higher degree of certainty.
