Patent ID: 7688592

Claim:
A cooling system for devices comprising power semiconductor components, the power semiconductor components being arranged on printed circuit boards along with non-power type semiconductor components, the printed circuit boards arranged in plug-in contact strips of a superordinate circuit carrier, the cooling system comprising: a cooling plate mounted in a pivotable manner, via a tilting mechanism extending from an edge of the cooling plate, to a tilting axis on a plug-in contact strip in a region of one of the power semiconductor components, and which can be pivoted about the tilting axis which extends parallel to the plug-in contact strip, and a cooling grid structure fitted on edges of the cooling plate and projecting in directions parallel to the plug-in contact strip; the cooling plate having a first mounting and maintenance position pivoted away from the power semiconductor component, and a second cooling and operating position wherein the cooling plate is pressed directly onto and covers only the power semiconductor component while the cooling grid structure does not contact or cover the power semiconductor device. but covers only the remaining non-power semiconductor components arranged on the printed circuit board adjacent to the power semiconductor component.
