ABSTRACT:
A power semiconductor component for liquid cooling, includes a semiconductor crystal disc which has at least one pn-junction and two main electrodes which are connected through thermally and electrically conducting multicontacts to thermally and electrically conducting heat sink discs. Together with a circular ceramic ring and further ring-shaped parts, the heat sink discs form a liquid-tight housing around which a cooling liquid can flow. The heat sink discs form the bottom of cooling capsules with a wall, a cover and cooling rods in the interior of the capsules, through which the coolant can flow. The cooling capsules are provided with openings for feeding in and discharging the coolant. The covers of the cooling capsule are provided with electrical connecting eyes. Two half-shells with hydraulic connecting eyes are provided as an outer insulating housing, having a multibranch canal system from holes formed in the connecting eyes of the half-shells to the cooling capsule openings.
