An electrical heating device comprises a housing which encloses a circulation chamber through which a medium can flow, and into which heating ribs protrude. Each of the heating ribs has a U-shaped recess which open into a uniform connecting chamber, which is separated from the circulation chamber by a partition wall provided in the region of the open ends of the U-shaped recesses, and which accommodates at least one PTC heating element that abuts oppositely situated inner sides of the U-shaped recess in heat-conducting contact. A housing cover bears a pump and forms a pump channel. The pump channel opens into an inlet opening of the pump, which is formed by a pump housing. |
