Device for controlling e.g. electrical auxiliary heater for electric vehicle, has printed circuit board fixed with heat coupling surface through connection pins for retaining thermal coupling of component to be cooled with coupling surface

摘要

The device (10) has a printed circuit board (46) arranged in a housing (12). A cooling body (34) is arranged in the housing, and has a heat receiving section (36) with a heat coupling surface (40) for thermally coupling with a component (50) to be cooled. Connection pins (28, 30, 32) are arranged adjacent to the coupling surface and designed as press-fit connection pins, and retaining bores (48) of the board are designed as through connection retaining bores. The board is fixed with the coupling surface through the pins for retaining thermal coupling of the component with the surface.
