Abstract (en)
An object is to provide a radiator capable of enhancing heat exchanging performance, and further reducing a refrigerant temperature at a refrigerant flow passage outlet, and a supercritical pressure refrigeration cycle using the same. A radiator 19 for radiating heat of a refrigerant whose pressure is supercritical pressure, including: multiple plate fins 31; and a plurality of refrigerant flow passages 34A to 34F formed by a heat transfer pipe group 33, wherein the refrigerant flow passages 34A to 34F include inlet heat transfer pipes 40A to 40C and outlet heat transfer pipes 42A1, 42A2, and intermediate heat transfer pipes 41A1 to 41C1, 41A2, 41B2, 41A3, 41B3, and a flow passage cross sectional area of the refrigerant flow passages 34A to 34F is gradually reduced from the inlet heat transfer pipes 40A to 40C to the outlet heat transfer pipes 42A1, 42A2.
