Patent ID: 11445634

Abstract:
A pushing action and a suction action are simultaneously performed on a working fluid passing through a heat transfer base, such that a heat exchange of cooling water can be efficiently performed, according to one embodiment of the present invention. To this end, a water pump for a water cooler for an electronic component, according to one embodiment of the present invention, comprises: a heat transfer base which is positioned at a lower portion and has an upper surface provided with a plurality of channels through which cooling water flows so as to exchange heat with the flowing cooling water; a base cover which is positioned at an upper portion of the heat transfer base so as to cover the top portions of the plurality of channels and has a first through hole and a second through hole vertically penetrating therethrough formed with a predetermined space from each other, wherein a first shaft fixing portion and a second shaft fixing portion are formed in the centers of the first and second through holes, respectively; an inlet impeller which rotates around a first shaft vertically installed on the first shaft fixing portion and pushes the cooling water to the upper surface of the heat transfer base; a discharge impeller which rotates about a second shaft vertically installed on the second shaft fixing portion and sucks the cooling water from the upper surface of the heat transfer base; a chamber portion, positioned at an upper portion of the heat transfer base, which has an inlet chamber and discharge chamber and has an inlet port communicating with the inlet chamber and a discharge port communicating with the discharge chamber formed on one side thereof, wherein the inlet chamber and the discharge chamber accommodate the inlet impeller and the discharge impeller thereinside, respectively; and a driving part including a first motor stator positioned above the inlet chamber and a second motor stator positioned above the discharge chamber.
