Abstract
A cooling pump includes a rotor including a rotation axis, a disc fixed with the rotation axis, an impeller fixed with the disc for pressurizing a liquid coolant, and a plurality of permanent magnets arrayed to be fixed with the disc in a ring shape; a case including a pump chamber holding the rotor rotatably, the pump chamber having an inlet and an outlet for the liquid coolant, wherein a part of the bottom wall forming the pump chamber is a heat-receiving portion; a cover including a recess, the cover sealing the case, i.e., pump housing, liquid-tightly; and a circular stator disposed in the recess, the stator generating a rotating magnetic field with a plurality of electromagnets to provide the rotor with torque around the rotation axis, wherein a hydrophilic surface is disposed on the inner surface of the pump chamber.
