Electical heating device of low height

摘要

The electrical heater, as an additional motor vehicle heater unit, has an open housing. The housing contains a layered structure (80) with at least one radiator (74), at least one heating unit (81) with at least one positive temperature coefficient (PTC) heater (78) and at least one spring (82) to hold the layered structure in place under tension. The structure has insulated contacts for the PTC heater. The housing has a lower section and at least one wedge displacement body to reinforce the holding tension on the layered structure at right angles to it.
