摘要

The device (1) has an electrical heating element (2) e.g. ceramic positive temperature coefficient heating element, received in a housing (7) for transferring heat through a wall (8) of the housing to a heating medium e.g. air or liquid. The electrical heating element is enclosed in the housing in a fluid-tight manner, and the wall of the housing is elastically stretched against the electrical heating element. A spring element (13) is arranged outside the housing, where the housing is formed by a metallic pipe.
