Title:
GAS-LIQUID SEPARATOR, AND REFRIGERATING DEVICE INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2011247575
Kind Code:
A
Abstract:

To solve a problem on degradation of separating performance found when a component mounting space is restricted in accompany with miniaturization of a refrigerating cycle unit, and miniaturization of each component and the gas-liquid separator are further required, on the other hand, as diameters of an inlet pipe to the gas-liquid separator and a gas-phase outlet pipe are determined on the basis of a prescribed refrigerating capacity of a product such as a refrigerating device, that is, a flow rate of a refrigerant, even when the gas-liquid separator is miniaturized, and the pipe diameters cannot be decreased in accordance with the miniaturization of the gas-liquid separator, the space between a container of the separator and the outlet pipe is narrowed.

In this gas-liquid separator in which a two-phase flow inlet pipe is disposed in a state of being shifted from a central line of the container from a side of an upper wall surface of the cylindrical container, the gas-phase outlet pipe is disposed in a state of vertically penetrating through the center of an upper end of the container, and a liquid-phase outlet pipe is disposed at a lower end of the container, the inlet pipe is mounted from a side face of the container so that a tip of the inlet pipe passes over the gas-phase outlet pipe, and an inclined section toward a center side of the inlet pipe is formed on a part of the inlet pipe reaching the tip of the inlet pipe opposed to the gas-phase outlet pipe, to prevent the inlet pipe from overlapping an outer diameter of the outlet pipe.
