Abstract
An electric heating device includes an electric control device with a control housing that is in structural unity with a housing of a power section. The power section has a frame forming a heating chamber. At least one PTC heating device with at least one PTC element and conductor elements is provided in the heating chamber. The control housing forms a chamber which is separated from the frame by a partition wall. A heat sink projects from the partition wall into the power section. The electric control device has a printed circuit board and at least one power switch which generates a power loss and which is connected in a heat-conducting manner to a surface of a heat sink. An electrically insulating layer and a spring element, which holds the power switch applied under pretension against the surface of the heat sink, are provided between the power switch and the heat sink.
