HEAT EXCHANGE DEVICE

PROBLEM TO BE SOLVED: To provide a heat exchange device in a simple structure, which uniformly cools an object to be cooled. SOLUTION: The heat exchange device 100 includes at least a freezing cycle including a compressor 1, a condenser 2, an expansion valve 3, a refrigerant storage tank 4, refrigerant piping 6 sequentially connecting the elements in order to make a refrigerant circulate, and a heat pipe 5 having a condensing part 52 inserted into the refrigerant storage tank and an evaporating part 51 exposed to the outside of the refrigerant storage tank. Heat exchanging with the cooled object is carried out in the evaporating part 51, and the refrigerant storage tank stores the liquid refrigerant and the gaseous refrigerant which is obtained by evaporating the liquid refrigerant via the heat exchange in the inside thereof, and the refrigerant passing through the expansion valve can flow into the refrigerant storage tank from an inlet side 41, and from an outlet side, the gaseous refrigerant can flow out of a gaseous refrigerant take-out part 42 provided on an upper part in the refrigerant storage tank.
