Abstract
An electric heating device a PTC heating element, a platelet-type PTC element which has two main side surfaces and face side surfaces extending perpendicular to the main side surfaces, and a casing. The casing forms inlet and outlet openings for the fluid to be heated and forms a circulation chamber in which a heat emitting surface of the PTC heating element is exposed and is coupled in a heat conductive manner to the PTC element. The PTC element is contacted in an electrically conductive manner by way of electrical conductor tracks to different polarities. A high degree of efficiency and a high output is obtained in that the conductor tracks are contacted in an electrically conductive manner to face side surfaces of the PTC element.
