Abstract
A semiconductor module cooler supplies a coolant to a water jacket from outside and cools a semiconductor device arranged on an outer surface of the cooler. The semiconductor module cooler has a heat sink thermally connected to the semiconductor device; a first flow channel arranged inside the water jacket with a guide section extending from a coolant inlet and having an inclined surface for guiding the coolant toward one side surface of the heat sink; a second flow channel arranged inside the water jacket in parallel to the first flow channel and extending to a coolant outlet; and a third flow channel formed inside the water jacket at a position connecting the first flow channel and the second flow channel. The coolant inlet and the coolant outlet are formed on a same wall surface of the water jacket, and the heat sink is arranged in the third flow channel.
