Abstract
An electrical heating device for a motor vehicle includes a frame that has openings formed on oppositely situated sides for the passage of a medium to be heated, a layer structure, arranged in the frame, and a connecting housing. The layer structure comprises layers of corrugated-rib elements and heat generating elements, and each heat generating element has at least one PTC element arranged between parallel contact plates. At least one power dissipation generating power switch is provided in the connecting housing. A heat sink lies exposed on the outside of the connecting housing. Improved and adequate cooling of the electrical heating device having the power switch is created as a result of the insertion of the heat sink into the connecting housing in a sealing manner.
