Heating arrangement using a P.T.C. resistance heating element

Abstract

Abstract 1. A heating device having a plate-shaped cold conductor (ceramic PTC) heating element which is metallized on both its flat faces and is of sandwich formation, plates made of sintered aluminium oxide adjoining both flat faces of the heating element, characterised in that for a one-piece sandwich (Figure 1), the surfaces of the aluminium oxide plates (2), which are respectively located opposite the plate faces (11), are metallized so as to be solderable ; that between the plate surfaces (11) and these metallized surfaces, a layer of ductile solder is in each case provided by means of which the heating element (1) and the aluminium oxide plates (2) are soldered to one another ; and that the terminal tags (22, 23) are soldered to the aluminium oxide plates (2) by means of the solder.
