Abstract
An electric heating device including PTC heating elements which have electrode sheets arranged on both sides thereof. These electrode sheets supply power to the PTC heating elements and each having connected thereto radiator elements for emitting the heat generated by the PTC heating elements. An electrically insulating layer is arranged between at least one of the electrode sheets and the respective radiator element.
Claims12
An electric heating device having a layered structure of a plurality of PTC heating elements and radiator elements, each PTC heating element being contacted by two electrode sheets so as to supply power thereto, and of said electrode sheets being connected to a radiator element in a heat-conducting manner,
- wherein an electric insulation is provided between one of said electrode sheets and the radiator element connected thereto, and
- wherein an insulating plate for electrically insulating the radiator elements is arranged between neighboring radiator elements.
