摘要

An electric heating device that provides additional heating for motor vehicles includes several heating elements assembled to form a heating block, and a controller for controlling the heating elements. The controller forms a constructional unit together with the heating block. Contact and/or cooler elements extend between the controller and the heating block. The controller is held at a control means support. Between the controller support and a heating block housing accommodating the heating block, sealing elements are provided through which the contact or cooler elements project and which are sealed by clamping between the controller support and the heating block housing.
