PURPOSE:To obtain a stable cooling performance by providing a cooler between a liquid reservoir and a suction-discharge pipe to prevent flow-out of a refrigerant from the liquid reservoir due to overheat of a heating body or the like in a circulation device wherein cooling is made by liquefying heated refrigerant vapor through condensation. CONSTITUTION:When the heating body 9 such as a semiconductor element and an electronic apparatus starts to heat and thereby the temperature rises, refrigerant vapor 7c is generated from refrigerant liquid 7a, goes into a condensor 3 through a vapor pipe 2 and is liquefied through condensation in the condensor, and refrigerant liquid 7d returns into an evaporator 1 through a return pipe 4. The heating body 9 is cooled by this circulation. When the heating body is overheated and the vapor penetrates into the liquid reservoir 6 through a connecting pipe 5, sealing by the liquid 8 turns impossible and the liquid flows out to the suction-discharge pipe 10. On this occasion, the refrigerant vapor is liquefied by a cooler 11 provided between the pipe and the liquid reservoir and connected with a refrigerator 12 and is returned to the reservoir 6 from the return pipe 12. By this constitution, the cooling device by boiling having the constantly stable cooling performance can be obtained. |
