As shown in FIG. 1, there is known a header distributor in which an inflow pipe 1 is connected to an inlet of a header 2 and a plurality of branch pipes 3 are arranged in a longitudinal direction of the header 2.

を均等に分配するのが困難であった。However, when a flow divider is provided between the condenser and the evaporator of the air conditioner, the state of the refrigerant is gas-liquid, that is, two phases of gas and liquid.
In the conventional header flow divider, a drift occurs between the branch pipes depending on the arrangement state of the branch pipes and the operation state of the air conditioner, and it is difficult to evenly distribute the refrigerant.

とができる。BEST MODE FOR CARRYING OUT THE INVENTION
This can be implemented by bundling a plurality of bent branch pipes, inserting them into the inflow pipe, and wrapping the inflow pipe and each branch pipe in a hollow body. Since the gas-liquid refrigerant flowing through the inflow pipe is branched into the inlets of the respective branch pipes in the inflow pipe having a small cross-sectional area, the gas-liquid refrigerant at the branch portion is difficult to be separated into a liquid component and a gas component. Further, since the cross-sectional area of the branch portion corresponding to the inlet of each branch pipe is small, the gas-liquid refrigerant collides with the branch portion at a high flow velocity and is agitated, and the state of the refrigerant in the branch portion becomes homogeneous. By the above-mentioned operation, a homogeneous refrigerant can be evenly distributed to each branch pipe.

体成分に分離され難く、攪拌効果を向上できる。Further, in the present invention, the cross-sectional shape of each branch pipe inserted into the inflow pipe has the same sector shape. Therefore, the cross-sectional area of the branch where the fan-shaped portions are gathered can be smaller than that of the other portion where the gas-liquid refrigerant flows, so that the gas-liquid refrigerant at the branch is difficult to be separated into the liquid component and the gas component, and the stirring effect is reduced. Can be improved.

ることができる。Further, in the present invention, the fan angle of the cross section of the insertion portion of each branch pipe is made larger at the upper part of the branch part than at the lower part. Therefore, the cross-sectional area of each branch pipe of the branch part becomes larger toward the upper side. The gas-liquid refrigerant flowing through the inflow pipe is separated into liquid and gas upward by the difference in specific gravity between liquid and gas. Therefore, by increasing the sectional area of each branch pipe toward the upper side, the mass flow rate of the refrigerant to each branch pipe can be equalized.

状態で均等に分配される。(Embodiment 1) In FIG. 1, circular branch pipes B1, B2, B3, and B4 are bundled and inserted into the tip of an inflow pipe 1, and the periphery thereof is joined. Branch pipe B1, B
2, B3 and B4 are bent at right angles to the inflow direction to change the outflow direction, and the inflow pipe 1 and the branch pipes B1, B
2, B3 and B4 are covered with a hollow body 4 so that the refrigerant does not leak. The hollow body 4 is composed of branch pipes B1, B2, B3, B4
The inflow pipe 1 and the branch pipes B1, B2, B3, and B4 are wrapped so that the flat plate 5 is bent just below the aggregate of the flat plates 5, and are joined at the joints of the flat plates 5. Therefore, the gas-liquid refrigerant flowing from the inflow pipe 1 collides with the branch section 6 and is agitated, and is uniformly distributed to the branch pipes B1, B2, B3, and B4 in the branch section 6 in a uniform state.

Other configurations are the same as those in the first embodiment, and a description thereof will be omitted. Therefore, the cross-sectional area of the branch portion 6 where the insertion portion 7 is gathered can be made smaller than the other portion where the gas-liquid refrigerant flows,
Separation of the liquid component and the gas component can be suppressed, and the stirring effect can be improved. Therefore, a homogeneous refrigerant can be evenly distributed to the branch pipes B1, B2, B3, and B4.

The other configuration is the same as that of the second embodiment, and will not be described. Each branch pipe B1, B2, B in the branch part 6 by the said structure
As shown in FIG. 3B, the cross-sectional areas of the branch pipes 3 and B4 are larger in the upper branch pipes B1 and B2 than in the branch pipes B3 and B4. Then, the gas-liquid refrigerant flowing through the inflow pipe 1 is separated into liquid and gas upward by the difference in specific gravity between liquid and gas. Therefore, the refrigerant that has been vertically gas-liquid separated can be distributed to the branch pipes B1, B2, B3, and B4 at an equal mass flow rate. The flow rate can be freely set for each of the branch pipes B1, B2, B3, and B4 by changing the fan angle A of the cross section.

入れることにより機能を維持することができる。Although each of the above embodiments has been described by taking four branches as an example, it goes without saying that the invention can be applied in the same manner as this embodiment as long as it has two or more branches. In addition, since the branching section 6 has a small cross-sectional area and branches perpendicularly to the inflow direction, the influence of gravity is small and there is no restriction on the installation direction. Further, when the number of branches increases and the diameter of the branch portion 6 increases, the function can be maintained by stopping down before the branch portion 6.
