Heating element and heating device containing a heating element

摘要

The element has a positive temperature coefficient (PTC) heating element (5) and elongate U-shaped insulating housings (2, 3) surrounding the PTC heating element. Electric conductor tracks (10) are in contact with the PTC heating element on opposing sides (1). Outer surfaces of each of the electric conductors are covered by an insulating layer (7) that has two interconnected plastic sheets, and the insulating layers are fixedly connected to the housing. The plastic sheets are connected to one another and enclose a knitted fiber fabric. An independent claim is also included for a heating device for heating air.
