Abstract

Official abstract text for this publication.

An electrical heating device, in particular for a vehicle, includes a heat exchanger body, with a heat transfer surface and an at least partially closed cavity. The at least partially closed cavity has a wall section that at least partially delimits the at least partially closed cavity that is adjacent to the heat transfer surface. A pyrotechnical charge is arranged in the at least partially closed cavity, and the at least partially closed cavity has a further wall section delimiting the at least partially closed cavity at least partially and to which an electrical connection line of the electrical heating device is adjacent.

First claim

Opening claim text (preview).

1 . Electrical heating device for a vehicle, comprising a heat exchanger body, with a heat transfer surface and an at least partially closed cavity, wherein the at least partially closed cavity has a wall section that at least partially delimits the at least partially closed cavity that is adjacent to the heat transfer surface, wherein a pyrotechnical charge is arranged in the at least partially closed cavity, and wherein the at least partially closed cavity has a further wall section delimiting the at least partially closed cavity at least partially and to which an electrical connection line of the electrical heating device is adjacent. 2 . The electrical heating device according to claim 1 , wherein the pyrotechnical charge is arranged at the wall section that partially delimits the at least partially closed cavity. 3 . The electrical heating device according to claim 1 , wherein the further wall section that partially delimits the at least partially closed cavity is opposite to the wall section that partially delimits the at least partially closed cavity. 4 . The electrical heating device according to claim 1 , wherein the at least partially closed cavity is at least partially formed within the heat exchanger body. 5 . The electrical heating device according to claim 4 , wherein the at least partially closed cavity is located between the heat transfer surface and a further heat transfer surface at which electrically generated heat is induced into the heat exchanger body. 6 . The electrical heating device according to claim 1 , wherein the at least partially closed cavity is at least partially formed outside of the heat exchanger body in a cover that also guides the electrical connection line. 7 . The electrical heating device according to claim 1 , wherein the further wall section that partially delimits the at least partially closed cavity is at least partially bordered by predetermined breaking points. 8 . Electrical heating device according to claim 1 , wherein the electrical connection line comprises at least one line's predetermined breaking point that is located in a region of the electrical connection line that is adjacent to the further wall section that partially delimits the at least partially closed cavity. 9 . The electrical heating device according to claim 1 , wherein an anvil is located within the at least partially closed cavity between the pyrotechnical charge and the further wall section that partially delimits the at least partially closed cavity. 10 . The electrical heating device according to claim 1 , wherein the pyrotechnical charge is located within a primer.
