The electrical unit has a printed circuit board (,) supporting the circuit, which includes a power component (,) which generates heat. In order to dissipate this heat from the power component, the power component rests on a heat conductive layer (,) which in turn is applied to the upper side (,) of the printed circuit board. This heat conductive layer further has a portion of the lid (,) of the housing resting on it, which serves as a cooling area. Alternatively, the cooling area can be a free-standing cooling element. The heat transfer thus takes place via the heat conductive layer (,) to the cooling element (,) so that the latter may be applied and formed independently of type and form of the power component.

Electrical device, in particular a switching and control unit for motor vehicles

In a control device the printed circuit board (,) rests on a rim (,) of the housing bottom (,). The power components (,) to be cooled are arranged in the area where the printed circuit board (,) rests on the rim (,). In order to achieve an even contact pressure of the printed circuit board (,) over the entire support surface, a contact pressure on the power component (,) or on the printed circuit board (,) is generated with the help of additional aids. It is possible here to use spring elements (,) or elastomer strips (,) acting on the power component (,). Furthermore, multi-part support elements (,), or respectively plastic elements (,) can also be employed, which respectively act directly on the printed circuit board (,). A good heat dissipation from the power component (,) via the rim (,) of the housing bottom is possible by means of this.

Control device, consisting of at least two housing parts

In order to provide protection against disruptive radiation and achieve good conduction of heat, a housing for control devices which has multiple parts is provided with a printed circuit board carrying power components and control elements with a peripherally extending lining of electrically and thermally conducting material. The printed circuit board is clamped between the housing halves in the region of the linings. The power components are contacted by the lining so as to be thermally conducting, while control elements which give off intensive disruptive radiation or are sensitive to such radiation are enclosed within connecting pieces projecting from the walls of the housing parts.
