PTC heating element and electric heating device for an automotive vehicle comprising such a PTC heating element

摘要

A PTC heating element is provided that includes including a PTC heating element strip conductors via which the PTC element is powered and at least one of which is insulated on an outer surface with an electrical insulation layer. In order to provide improved insulation while maintaining adequate heat transfer from the PTC element to the heat-emitting surface through the electrical insulation layer, the electrical insulation layer comprises a film and an electrically insulating mass of good thermal conductivity applied to the film. Also provided is an electric heating device for an automotive vehicle that is provided with at least one PTC heating element of such a type.
