Abstract

Official abstract text for this publication.

A PTC heating assembly has a plurality of PTC elements and electric strip conductors between which the PTC elements are provided and which are electrically conductively connected to the PTC elements The PTC heating assembly also includes a frame which forms at least one receptacle for the PTC elements and which is provided between the strip conductors. For adjusting the heating power of the PTC heating assembly, at least two strip conductors on at least one side of the PTC elements are electrically conductively connected to PTC elements which deviate from one another.

First claim

Opening claim text (preview).

The invention claimed is: 1 . A PTC heating assembly comprising: a plurality of PTC elements; electric strip conductors between which the PTC elements are provided and which are electrically conductively connected to the PTC elements; and a frame forming at least one receptacle for the PTC elements, wherein the frame is provided between the strip conductors; wherein a plurality of the strip conductors are provided on a first side of the PTC elements and a plurality of the strip conductors are provided on a second opposite side of the PTC elements opposite the first side; and wherein at least one of the strip conductors on the first side of the PTC elements is electrically conductively connected to a plurality of PTC elements which are electrically conductively connected to different opposite strip conductors on the second side of the PTC elements. 2 . The PTC heating assembly according to claim 1 , wherein a plurality of the strip conductors are provided on a first side of the PTC elements, and a single strip conductor is provided on a second side of the PTC elements opposite the first side. 3 . The PTC heating assembly according to claim 2 , further comprising electric insulating layers covering the electrical strip conductors on the second side of the PTC elements. 4 . The PTC heating assembly according to claim 3 , wherein the electric insulating layers are each connected to the frame. 5 . The PTC heating assembly according to claim 1 , further comprising electric insulating layers covering the electrical strip conductors on the second side of the PTC elements. 6 . The PTC heating assembly according to claim 5 , wherein the electric insulating layers are each connected to the frame.
