Document Type and Number:
WIPO Patent Application WO/2016/056086
Kind Code:
A1
Abstract:
The purpose of the present invention is to enable a divider to equally distribute a refrigerant. A refrigerant pipe (20) is provided with a bent pipe (23) formed in a curved line shape and a downstream pipe (24) formed in a straight line shape and connected to the downstream end of the bent pipe (23). A divider (25) for distributing a refrigerant to a plurality of flow passages (26) is connected to the downstream end of the downstream pipe (24). The inner peripheral-side inner wall of the bent pipe (23), which faces toward the center of curvature of the curved line, is formed as a grooved surface (28) having a groove formed therein, and the outer peripheral-side inner wall of the bent pipe (23), which faces away from the center of curvature of the curved line, is formed as a smooth surface (29).
