Since the refrigerant flowing into the inside is in a gas-liquid two-phase state, a part of the liquid phase L collides and falls on a wall surface around the upper outlet 4 to fall into the body 3.
A liquid pool is formed by stagnating and circulating in the lower portion, and at the same time, a part of the gas phase G is stagnating and circulating in the upper portion of the body 3 to form an air pool. Therefore, the liquid pool is agitated by the gas-liquid two-phase refrigerant supplied from the inflow pipe 5 and the liquid surface pulsates, and the amount of the liquid phase refrigerant distributed to each outlet 4 becomes non-uniform. As a result, each outflow pipe 6 There was a problem that the refrigeration capacity of the heat exchange unit configured thereafter becomes unstable. When the refrigerant flow divider 1 is installed at an angle to the vertical direction, the liquid phase L retained at the lower part of the body 3
Is flowing to the outlet 4 on the lower side in the vertical direction, the gaseous phase L flows more in the outlet 4 on the upper side in the vertical direction, and as a result, the refrigerating capacity of the heat exchange section formed after each outlet pipe 6 varies. Had. Further, the trunk 3 of the refrigerant flow divider 1
Since a liquid pool is formed in the lower portion and the liquid phase L stays, there is also a problem that the amount of refrigerant charged into the system increases as a refrigerant cycle.

In the integrally formed refrigerant flow divider having a plurality of outflow ports, a predetermined position between the inflow port and the outflow port is reduced and a throttle portion is provided, so that gas-liquid separation flowing from the inflow pipe is performed. The flow of the compressed refrigerant is contracted and jetted by the restricting action of the restricting portion, and this flow is caused to collide with the opposing collision wall, and the gas flow is caused by the nozzle effect of the restricting portion and the collision, stirring, and mixing action at the collision wall. The uniformity of the mixed state is promoted, and since the volume surrounded by the narrowed portion, the collision wall and the peripheral wall is small, a plurality of outlet pipes are kept in a uniform gas-liquid mixed state without liquid pool or air pool. The flow is evenly distributed to a plurality of outlets connected to the outlet. Also,
