Abstract
A water-cooled motor controller includes a capacitor, a water-cooled plate, and a power module stacked in a controller housing. The power module is fixedly connected to the water-cooled plate. The water-cooled plate is provided with a cooling medium flow channel on one side facing the power module, and the other side of the water-cooling plate on which the cooling medium flow channel faces away from the power module side contacts the capacitor through an insulating and thermally conductive material for heat exchange. The water-cooled plate and the controller housing are fixedly connected to each other with a cooling medium passage provided therebetween. A cooling medium flows in from the controller housing, and then flows out of the controller housing after being heat exchanged by the water-cooled plate. The present invention utilizes upper and lower surfaces of the water-cooled plate to dissipate heat from the capacitor and the power module simultaneously.
