Abstract
A semiconductor module cooler for supplying a refrigerant from exterior into a water jacket and cooling a semiconductor device disposed on an outer surface of the cooler, includes a heat sink thermally connected to the semiconductor device; a first flow path extending from a refrigerant inlet and arranged with a guide portion having an inclined surface for guiding the refrigerant toward one side surface of the heat sink; a second flow path extending toward a refrigerant outlet and formed with a sidewall parallel to the other side surface of the heat sink; a flow velocity adjustment plate disposed in the second flow path and formed parallel to the other side surface of the heat sink at a distance therefrom; and a third flow path formed at a position communicating the first flow path and the second flow path. The heat sink is disposed in the third flow path.
