Title:
HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2017/175724
Kind Code:
A1
Abstract:
A heat exchanger (300) is provided with: a heat exchanging part (34); a liquid reservoir (36) in which gas-liquid separation of a gas-liquid double-phase refrigerant, which has flowed out of the heat exchanging part (34), into a gas-phase refrigerant and a liquid-phase refrigerant is carried out, and the liquid-phase refrigerant is retained; an inflow passage (12) that allows the gas-liquid double-phase refrigerant that flows out of the heat exchanging part (34) to flow into the liquid reservoir (36); a gas-phase outflow passage (13) that allows the gas-phase refrigerant to flow out of the liquid reservoir (36); and a liquid-phase outflow passage (14) that allows the liquid-phase refrigerant to flow out of the liquid reservoir (36). The inflow passage (12) is connected so as to communicate with an inflow port (81a) provided above the liquid surface of the liquid-phase refrigerant in the liquid reservoir (36). The gas-phase outflow passage (13) is connected so as to communicate with a gas-phase outflow port (81b) provided above the liquid surface of the liquid-phase refrigerant in the liquid reservoir (36). The liquid-phase outflow passage (14) is connected so as to communicate with a liquid-phase outflow port (81c) provided below the liquid surface of the liquid-phase refrigerant in the liquid reservoir.
