ABSTRACT:
The protective housing (11) of the module IS placed in the manner of a cap on the outer edge (3) of a cooling body (1), on whose heat contact surface (5) facing the protective housing (11) lie the power components (9) or the circuit bearer (6) of a hybrid circuit (8). The protective housing (11) is made of plastic and has integrated clamp and lock areas (12, 13). The outer edge (3) of the cooling body (1) is fashioned so that by placing on of the protective housing (11) an annular positive and frictional connection can be produced between the protective housing (11) and the cooling body (1). The placing on simultaneously effects the surface pressure between the power components (9) and a heat contact surface (5) of the cooling body (1) by means of frictional connection elements (16, 17, 21) arranged between the power components (9) and the protective housing (11). Using this modular construction, the production of the thermal coupling to the cooling body (1), which would otherwise be additionally required, can be integrated into the cooling body/protective housing assembly procedure.
