摘要

The heater has a housing with an air inlet and air outlet. An insulating plate (8) is arranged in the housing between a heating unit (5) and a housing wall. A gap is provided between heating unit and the insulating plate. The insulating plate has a stabilizing form (9) that resists contact of the insulating plate with the heating unit during thermal expansion of the insulating plate.
