In the use of the refrigerant, the refrigerant flowing into the main flow distributor 11 from the inflow pipe 6 connected to the condenser (not shown) is in a two-phase flow state of a gas phase and a liquid phase. Now, as shown by the arrow in FIG. 1, the refrigerant a flowing from the inflow port 15 of the inflow pipe 6 is directed to the fluid collision surface 23 at the center of the facing surface of the outflow forming plate 16 facing the inflow port 15. collide. As described above, the refrigerant a (gas phase and liquid phase) from the inflow pipe 6 is applied to the fluid collision surface 2
As a result, all the refrigerant bounces evenly and is uniformly dispersed, resulting in a good gas-liquid two-phase mixing state. In this state, the refrigerant further hits the tapered wall 12c of the mantle member 12 and is guided by the tapered wall 12c. Then, the coolant a flows out from the outlets 17, 18, 19 formed in the outlet forming plate 16 to the corresponding outflow pipes 7. Thus, the refrigerant a
Once collides with the fluid collision surface 23, and the refrigerant a, which is uniformly mixed in a good gas-liquid two-phase state, is further guided by the tapered wall 12c of the mantle member 12 so that the refrigerant a has substantially uniform flow conditions. Outflow port 1 of outflow forming plate 16 without receiving pressure loss
Since the refrigerant a passes through the outlets 7, 18 and 19, the flow rate of the refrigerant a to each branch / outflow pipe 7, 7 per unit is proportional to the diameter of the outlets 17, 18 and 19.
