Abstract

An electric heating device including a heater housing in which a partition separates a circulation chamber, through which a medium to be heated can flow, from a connection chamber in which electrical connections of a PTC heating element introduced into a recess of a heating rib projecting from the partition into the circulation chamber are exposed. The PTC heating element has at least one PTC element and strip conductors lying against it at both sides, of which at least one strip conductor is covered by an electrical insulation layer. To create an electric heating device which permits a delivery of heat of the PTC heating element to the environment in an improved way, the heating rib is formed by a heating rib frame which comprises at least one window in which the insulation layer is exposed.
