GAS-LIQUID SEPARATOR AND REFRIGERATING APPARATUS EQUIPPED THEREWITH

摘要

[PROBLEMS] To provide a gas-liquid separator miniaturized and further enhanced in performance by a surface tension effect. [MEANS FOR SOLVING PROBLEMS] The gas-liquid separator for separating gas-liquid two-phase flow into a gas phase and a liquid phase has a gas-liquid separating mechanism wherein a narrow space is formed in back wash of an inlet pipe of gas-liquid two-phase flow by an inlet partition body a part of which roughly abuts on the groove top of a grooved surface, and wherein a sharply enlarged part is provided in back wash of the inlet partition body so that the gas-liquid two-phase flow is led through the narrow space to a gas-liquid separating chamber and that the liquid phase is held in the groove on the grooved surface by the surface tension effect and continues to flow in the groove, while the gas phase is separated from the liquid phase and goes out of the groove. For carrying out favorable gas-liquid separation, there are provided a relationship between two-phase flow mass flow rate (G) and in-groove flow path cross-sectional area (S1) as well as groove width (b), a ratio of groove width (b) to groove depth (h), b/h, and inflow conditions for directing toward the groove of the two-phase flow along the groove.
