Abstract
A cooling device comprises a circulation passage through which a liquid coolant flows, and a pump provided in the circulation passage configured to circulate the liquid coolant along the circulation passage. The pump includes, (1) a pump casing including a pump chamber into which the liquid coolant flows, (2) an impeller mounted in the pump chamber to push out the liquid coolant from the pump chamber to the circulation passage, and (3) an injection portion provided in the pump casing configured to inject the liquid coolant to the pump chamber.
Claims20
A cooling device, comprising:
- a circulation passage through which a liquid coolant flows;
- and
- a pump provided in the circulation passage to circulate the liquid coolant along the circulation passage, the pump including,
- (1) a pump casing including a pump chamber into which the liquid coolant flows,
- (2) an impeller mounted in the pump chamber to output the liquid coolant from the pump chamber to the circulation passage, and
- (3) an injection portion provided in the pump casing to inject the liquid coolant into the pump chamber.
A cooling device, comprising:
- a circulation passage through which a liquid coolant absorbing a heat of a heat generating element flows;
- a heat radiation portion arranged in the circulation passage to radiate the heat that the liquid coolant conveys;
- and
- a pump provided in the circulation passage configured to circulate the liquid coolant along the circulation passage, the pump including,
- (1) a pump casing including a reserve tank to reserve the liquid coolant and a pump chamber which communicates with the reserve tank,
- (2) an impeller mounted in the pump chamber to output the liquid coolant from the pump chamber to the circulation passage,
- (3) a first opening portion provided in the pump casing, and
- (4) a second opening portion provided in the pump casing.
An electronic apparatus, comprising:
- a housing in which a heat generating element is arranged;
- and
- a cooling device housed in the housing to radiate heat generated by the heat generating element by using a liquid coolant, the cooling device including:
- a circulation passage through which the liquid coolant flows, and
- a pump provided in the circulation passage configured to circulate the liquid coolant along the circulation passage, the pump including,
- (1) a pump casing including a pump chamber into which the liquid coolant flows;
- (2) an impeller mounted in the pump chamber to output the liquid coolant from the pump chamber to the circulation passage, and
- (3) an injection portion provided in the pump casing configured to inject the liquid coolant to the pump chamber.
