Abstract
A PTC heating element for an electric heating device includes frame which is made of electrically non-conductive material and which encloses at least one PTC element, conductor tracks electrically connected to the PTC element, and insulating layers bearing, in a heat-conductive manner, against an oppositely disposed main side surface of the PTC element. The frame has contact strips which project over itself and which are electrically conductively connected to the conductor tracks for energizing the PTC element with different polarities. In order to provide an electrically well-insulated PTC heating element allows good heat coupling, s a film respectively covers the outer surfaces of the insulating layers. A corresponding PTC heating element may be provided in a circulation chamber of the electric heating device. In this case, the conductor tracks are electrically connected to the PTC element, protrude through a partition wall of the electric heating device, and are exposed and electrically connected in a connection chamber. The connection chamber is separated by the partition wall from the circulation chamber.
