A cooler (11) cools target equipment (2) by using latent heat from vaporization of a hydraulic fluid. A cold heat source-type heat exchanger (12) uses the cold heat of a low-temperature, low-pressurerefrigerant circulating through a freezing cycle (30), radiates heat from hydraulic fluid that has vaporized in a cooler (11), and condenses the hydraulic fluid. An air cooled heat exchanger (13) usescold heat of external air, radiates heat from hydraulic fluid that has vaporized in the cooler (11), and condenses the hydraulic fluid. The cooler (11), the cold heat source-type heat exchanger (12),and the air cooled heat exchanger (13) are connected by a gas pipe (14) and a liquid pipe (15). An external air temperature detection unit (16) detects external air temperature. A saturation temperature detection unit (17) detects the saturation temperature of hydraulic fluid circulating through a thermosiphon circuit (10). Heat radiation amount adjustment units (18, 20, 31, 33, 38, 41, 321, 322)adjust the amount of heat radiation from the hydraulic fluid flowing through the cold heat source-type heat exchanger (12), such that the saturation temperature of the hydraulic fluid is higher thanthe external air temperature.
冷却器(11)通过工作流体的蒸发潜热来冷却对象设备(2)。冷热源式热交换器(12)利用在制冷循环(30)中循环的低温低压的制冷剂的冷热而使在冷却器(11)中蒸发的工作流体散热,使工作流体冷凝。空冷式热交换器(13)利用外部空气的冷热而使在冷却器(11)中蒸发的工作流体散热,使工作流体冷凝。冷却器(11)、冷热源式热交换器(12)和空冷式热交换器(13)通过气体配管(14)和液体配管(15)而连接。外部空气温度检测部(16)检测外部空气温度。饱和温度检测部(17)检测在热虹吸回路(10)中循环的工作流体的饱和温度。散热量调整部(18、20、31、33、38、41、321、322)调整在冷热源式热交换器(12)中流动的工作流体的散热量,以使工作流体的饱和温度比外部空气温度高。
