Abstract
A heat generating element for an electrical heating device of a motor vehicle includes a positional frame which forms a receptacle in which a PTC element is accommodated, and two contact plates abutting on oppositely situated sides of the PTC element. A heat generating element has a sheet metal cover that is connected to the positional frame. Also provided are a frame, which has oppositely situated side openings for the passage of a medium to be heated, and a layer structure, which is arranged in the frame and which comprises layers of corrugated-rib and heat generating elements, such that the heat generating element has at least one PTC element arranged between two parallel contact plates. The electrical heating device is protected against EMC via sheet metal covers that are arranged on both sides of the heat generating element and between the corrugated-rib elements and the contact plates.
