Abstract

The invention under consideration relates to an electric heating device for heating a flowing medium with a housing, in which the at least one electric heating element of the electric heating device is held securely and fully shielded from the medium held in the circulation chamber by a separating wall that divides the housing into a heating chamber and a circulation chamber. The circulation chamber has inlet openings and outlet openings for introducing and removing, respectively, the medium. The heating element is preferably a PTC heating element and is held by means of a clamping force in a recess formed by the separating wall, said recess preferably projecting into the circulation chamber. The invention furthermore relates to a recuperator for converting electrical energy into thermal energy, particularly for an electric drive in a vehicle.
