1. A process for conducting operating heat of a semiconductor switch to a heating cell which is triggered by the semiconductor switch, comprising the steps of:
- providing a cooling fin on the semiconductor switch;
placing said semiconductor switch over a surface of a first heat and current conducting material strip, said first heat and current conducting material strip being electrically connected to a supply voltage;
placing said first heat and current conducting material strip over a surface of a second heat and current conducting material strip with a heat-conducting insulating film located between the first and second heat and current conducting material strips;
placing said second heat and current conducting material strip on a surface of a frame terminal;
providing a heating cell;
electrically and thermally connecting said frame terminal to said heating cell;
placing said frame terminal on a surface of a second heat-conducting insulating film;
providing a supply terminal; and
then placing said heat-conducting insulating film on a surface of said power supply terminal.

Abstract
A heating element and a process for conducting the operating heat of a semiconductor switch to a heating cell which is triggered by the semiconductor switch via first and second heat and current conducting material strips and a frame terminal with an interposed heat-conducting insulating film. The semiconductor switch is provided with a cooling fin and is applied directly to a surface of the first heat and current conducting material strip.
