Patent ID: 8261813

Claim:
An electronic device cooling apparatus which allows refrigerant liquid to circulate and flow in a cooling system by using a pump so as to cool a heat generating portion of an electronic device, the apparatus comprising: a heat generating portion cooling unit which is connected to the pump and releases heat received from the heat generating portion to the refrigerant liquid through a fin portion so as to cool the heat generating portion; and a refrigerant cooling portion which cools the refrigerant liquid that has received heat from the fin portion, the refrigerant liquid flowing out of the heat generating portion cooling unit, wherein the heat generating portion cooling unit includes therein separately a first flow channel through which the refrigerant liquid discharged from a discharging port of the pump flows to the outside of the heat generating portion cooling unit through the fin portion which forms a part of the first flow channel, and a second flow channel through which the refrigerant liquid that is guided to the outside and passes through the refrigerant cooling portion flows towards a sucking port of the pump, each of the first and second flow channels being sealed with a pressing member which is made of flexible material and located in the heat generating portion cooling unit, and the pressing member forming a part of each of the first and second flow channels; and wherein each of the discharging port and the sucking port of the pump is connected to the heat generating portion cooling unit through a piping member.
