Abstract
An electrical heating device includes a housing which encloses a circulation chamber through which a medium can flow and in which heating ribs protrude. The heating ribs are in thermally conducting contact with at least one PTC heating element. A control device is provided in a constructional unit with at least one assembled conductor board. The constructional unit is accommodated in a control housing that comprises a control housing cover and a control housing frame. The control housing frame circumferentially surrounds the assembled conductor board and is formed from a metallic material. During the installation of the control housing on the housing, a control element, producing a power loss, is held by the assembled conductor board and is placed in abutment with a cooling element formed on the housing.
