Abstract: A process manufactures a PTC heating element (10) that includes at least one PTC component (20) and, on at least one side (50, 52) of the at least one PTC component (20), at least one carrier (14, 16) permanently connected to the PTC component (20). The process includes arranging solder material (46, 48) between the one side of the at least one PTC component (20), which side is to be permanently connected to the at least one carrier (14, 16), and the at least one carrier to be connected on this side of the at least one PTC component (20). The solder material (46, 48) is melted by induction soldering to connect the at least one PTC component (20) to the at least one carrier (14, 16).

Abstract: A PTC heating element and an electric heating device containing such a PTC heating element are disclosed. The PTC heating element comprises two insulating layers with a metallic coating provided on one side and a PTC element arranged therebetween which is provided on oppositely disposed main side surfaces with a respective metallization which is electrically conductively connected to the coating of one of the insulating layers. The metallization provided on one of the main side surfaces is assigned only to one potential for energizing the PTC element. The metallization provided on the other main side surface is assigned to only the other potential for energizing the PTC element. The metallization of the one main side surface of the PTC element and the metallization of the other main side surface of the PTC element are formed in such a way that the current path (P) through the PTC element is extended relative to the thickness (D) of the PTC element.

The PTC element is provided on oppositely disposed main side surfaces with a respective metallization which is electrically conductively connected to the coating of one of the insulating layers The metallization provided on one of the main side surfaces is assigned only to one potential for energizing the PTC element, and the metallization provided on the other of the main side surfaces is only assigned to the other potential for energizing the PTC element, as well as an electric heating device containing such a PTC heating element. With regard to better heat decoupling, the insulating layer may be glued to the PTC element, and the coating of the insulating layers is in direct electrically conductive contact with the metallization of the PTC element.
