わされる。In other words, the gas-liquid two-phase fluid (4) that has flowed into the distribution pipe (1)
, [vapor phase (4a) and liquid phase (4b)] rise on the inner peripheral surface as an annular flow with a substantially uniform liquid film thickness. Therefore, the liquid film passing through the inlet of each capillary (2)
). The flow rate of liquid flowing into each capillary is expressed by the following equation based on the relationship between the distribution pipe (1) and each capillary (2).
３６０ ＤここでＧ

is the flow rate of the outflow from the capillary, Giu is the flow rate of the inflow, D is the inner diameter of the distribution tube, d is the inner diameter of the capillary, and θ is the above angle.
したがって分配管の内径りが一様で、かつ複数の分流用
細管の内径ｄがすべて同じ分配器では下流側の細管はど
流入液流量が小さくなるため、流出液流量も低下するこ
とになる。Therefore, in a distributor in which the inner diameter of the distribution pipe is uniform and the inner diameter d of all the plurality of dividing thin tubes is the same, the flow rate of inflow liquid in each of the thin tubes on the downstream side will be small, and the flow rate of outflow liquid will also be reduced.

る。Therefore, as shown in the embodiment shown in FIG. 1, the inner diameter of the distribution pipe (1) is continuously reduced in the flow direction of the fluid passing through the interior, and the diameter on the downstream side is made smaller, so that four pipes can be connected to each other. This is intended to equalize the flow rate of liquid flowing out from the capillary.

細管（２）からの流出液流量を均等にすることができる
。In the embodiment shown in FIG. 1 above, the inner diameter of the distribution pipe is continuously reduced on the downstream side of the fluid to equalize the flow rate of liquid flowing into each capillary. As shown in another embodiment of the present invention in Figure 3, even if the inner diameter of the distribution pipe is gradually reduced on the downstream side of the fluid, the flow rate of the liquid flowing out from each capillary tube (2) can be made equal. .
