Abstract
Claims
1. A liquid-cooled pump device, comprising: A housing comprising a liquid inlet, a bottom opening, a top opening, and a liquid outlet; A top assembly for mounting to the top opening of the housing, the top assembly comprising: a cover for coupling to the top opening and forming an impeller chamber; an impeller for being disposed in the impeller chamber; and a motor for being disposed on the cover, the motor including a circuit board, a stator and a rotor, the circuit board being disposed on the cover, the stator being disposed on the circuit board, and the rotor being coupled to the impeller; and a bottom assembly for mounting to the bottom opening of the housing, the bottom assembly comprising: a cover membrane; and a base for coupling to the bottom opening and forming a heat exchange chamber with the cover membrane, the base being thermally coupled to a heat source; And a water guide plate, which is installed on the heat exchange chamber.
2. The liquid-cooled pump device as claimed in claim 1, wherein the impeller, the motor, and the cover are assembled in a sequentially stacked manner.
3. The liquid-cooled pump device as claimed in claim 1, wherein the water guide plate, the cover membrane, and the base are assembled in a sequentially stacked manner.
4. The liquid-cooled pump device as claimed in claim 1, wherein the impeller includes a disc-shaped portion and at least one blade for coupling to the disc-shaped portion, and the blade extends longitudinally toward the housing when assembled.
5. The liquid-cooled pump device as claimed in claim 1, wherein the top assembly includes a top sealing ring located between the housing and the cover, and the bottom assembly includes a bottom sealing ring located between the housing and the base.
6. The liquid-cooled pump device as claimed in claim 1, wherein the stator and the rotor are arranged along a rotational axis of the impeller.
7. The liquid-cooled pump device as claimed in claim 1, wherein the bottom assembly includes a fin structure located in the heat exchange chamber and the fin structure is thermally coupled to the base.
8. The liquid-cooled pump device as claimed in claim 1, wherein the water guide plate includes a first opening, at least one second opening, and a central platform, the first opening being adjacent to one side of the water guide plate and arranged along a longitudinal axis of the water guide plate, the second opening being arranged along the other side of the water guide plate, and the central platform being arranged along the longitudinal axis of the water guide plate and in fluid communication with the second opening.
9. The liquid-cooled pump device as claimed in claim 8, wherein the water guide plate includes a groove disposed on the opposite side of the central platform, the groove being in fluid communication with the first opening and the heat exchange chamber.
10. The liquid-cooled pump device as claimed in claim 9, wherein the trench includes a first portion and a second portion, the first portion being in fluid communication with the first opening and having a progressive depth, and the second portion having a constant depth equal to the minimum depth of the first portion.
11. The liquid-cooled pump device as claimed in claim 9, wherein the first opening and the groove form a first connecting channel, the second opening and the central platform form a second connecting channel, the liquid inlet is in fluid communication with the heat exchange chamber through the first connecting channel, the heat exchange chamber is in fluid communication with the impeller chamber through the second connecting channel, and the impeller chamber is in fluid communication with the liquid outlet.
12. The liquid-cooled pump device as claimed in claim 8, wherein the water guide plate includes two second openings, each of the two second openings extending along opposite sides of the central platform, the opposite sides of the central platform being parallel to the longitudinal axis of the water guide plate.
13. A liquid-cooled pump device, comprising: A housing includes a liquid inlet, a partition, a top sidewall, a bottom sidewall, and a liquid outlet, the liquid inlet and the liquid outlet being arranged on the same side of the housing; a cover for forming an impeller chamber with the partition and the top sidewall; an impeller for being disposed in the impeller chamber; a motor for being disposed on the cover, the motor having a stator and a rotor, the stator being disposed on the cover and the rotor being coupled to the impeller; a base for being coupled to the housing and thermally coupled to a heat source; a covering membrane for forming a heat exchange chamber with the base; and a water guide plate for being disposed on the heat exchange chamber.
14. The liquid-cooled pump device as claimed in claim 13, wherein the water guide plate, the cover membrane, and the base are assembled in a sequentially stacked manner.
