Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a heat exchange unit having a high heat exchange rate and controlling refrigerant temperature highly accurately. SOLUTION: The heat exchange unit for cooling a circulation refrigerant inside a transport pipe is provided with an external refrigerant tank 2 for storing an external refrigerant 6. The external refrigerant 6 is stored in the external refrigerant tank 2 and cooled by a cold head 4. The transport pipe 5 is immersed in the external refrigerant to cool the circulation refrigerant flowing through the inside of the transport pipe. The transport pipe 5 is efficiently cooled by the external refrigerant 6 from the whole outside circumference, and a heat exchange rate is improved. Controlling a temperature of the external refrigerant 6 by a temperature sensor 8 enables the temperature of the external refrigerant easily to be controlled.
