Abstract:
1. A refrigerant cycle device comprising: a compressor for sucking and compressing a refrigerant; a radiator having a heat radiating portion for radiating high-pressure refrigerant discharged from the compressor, and a refrigerant outlet downstream from the heat radiating portion in a refrigerant flow direction; an ejector that includes a nozzle portion for decompressing and expanding refrigerant, a refrigerant suction port for sucking refrigerant by high-velocity refrigerant flow jetted from the nozzle portion, and a pressure increasing portion in which the high-velocity refrigerant flow and the refrigerant flow sucked from the refrigerant suction port are mixed and the refrigerant pressure is increased by decreasing velocity of the mixed refrigerant flow; a throttle unit for decompressing refrigerant flowing from the refrigerant outlet of the radiator; an evaporator located between a refrigerant downstream side of the throttle unit and the refrigerant suction port, for evaporating the refrigerant from the throttle unit; and a branch portion located in the heat radiating portion upstream of the refrigerant outlet for branching a refrigerant flow from within the heat radiating portion of the radiator, wherein the nozzle portion has a nozzle inlet coupled to the branch portion.
