Abstract

Air heating device comprising a frame (11), a plurality of box sections (16) and PTC-tablets (25). The PTC-tablets (25) are positioned between the box sections (16), functioning as heat sinks. The box sections (16) are extruded from aluminum or aluminum alloys and these extrusions are provided with fins (19,20). The PTC-tablets are connected to the box sections by a conductive adhesive. The invention also relates to an air heating assembly comprising several air heating devices. <IMAGE>
