To improve the heat exchange efficiency of a gas cooler by preventing a refrigerant on the inlet side of the gas cooler and a refrigerant on the outlet side of the gas cooler from exchanging heat with each other.
Heat exchangers 1, 1a functioning in a refrigerating cycle using a supercritical refrigerant comprise heat transfer tubes 2, 2a and a plurality of heat transfer fins 3, 3a. The heat transfer tubes allow the supercritical refrigerant to flow through. The plurality of heat transfer fins are connected to the heat transfer tubes to assist the heat exchange between a first fluid and the supercritical refrigerant in the heat transfer tubes. The plurality of heat transfer fins are arranged separated with respect to the flow direction R1 of the supercritical refrigerant.
