摘要：
An electric heating device includes a plurality of heating elements which are assembled to form a block. Such a heating element is formed from two metal plates, with the interposition of PTC elements. In order to increase the heat transfer, the metal plates are provided with corrugation ribs. Each heating element includes a pair of metal plates which are angled off essentially in the form of an L such that the angled-off sections are connected in a frictionally locking manner to each other. The angled-off sections are arranged at opposite ends of the heating elements and angled in opposite directions, the length of the angled-off sections of the metal plates being dimensioned such that angled-off sections of one pair of metal plates are in mutual abutment with angled-off sections of respectively adjacent pairs of metal plates.
