Abstract

An electric heating device includes a casing which forms inlet and outlet openings for a fluid to be heated and a circulation chamber communicating with the inlet and outlet openings, and into which at least one PTC heating element with at least one PTC element projects which is, for electrical contact, provided with contact strips which are exposed in a connection chamber which is separated from the circulation chamber by way a partition wall. The casing further forms a control chamber for accommodating a control device which, with regard to controlling, is coupled to the at least one PTC heating element. An integrally formed casing base member, made of a plastic material, forms the partition wall and walls which circumferentially surround the circulation chamber and the connection chamber.
