Composite panel including a heating resistor

摘要

The element (10) has a sheet-like heating element (15) e.g. heating foil, arranged between an upper cover plate (11) and a lower cover plate (18). An auxiliary intermediate layer (13) is arranged on both sides of the heating element, where the element is sealed in lateral edge region in a plane of the heating element. The cover plate is made of heat-conductive material such as aluminum, and the heating element is connected with the cover plate in a heat conductive manner on a side turned towards the cover plate and the intermediate layer is made of polypropylene. .
