Field of the Invention The present invention relates to a refrigerant distributor for branching a refrigerant circuit in a refrigerating cycle such as an air conditioner or a refrigerating machine into a plurality of refrigerant circuits, and in particular, a refrigerant which can realize uniform refrigerant distribution. It is about a shunt.

In order to promote the efficiency of the heat exchanger, the diameter of the refrigerant pipe has been reduced, and as a result, many refrigerant shunts have been used and many proposals have been made. One of the problems relating to the improvement of the refrigerant flow divider is to divide the refrigerant at an equal or predetermined ratio.

１０３へ夫々流出していく。More specifically with reference to the drawings, first, the one shown in FIG. 7 is the most basic shunt,
This flow diverter is composed of one hollow tubular inflow pipe 101 and two outflow pipes 1 of the same diameter that are vertically branched from the inflow port 101.
02 and 103, and a branch space 104 for dividing the refrigerant a from the inflow pipe 101 into the outflow pipes 102 and 103. In this flow divider, the refrigerant a flows in from the inflow pipe 101 as a two-phase flow of the gas phase a1 and the liquid phase a2, and is slightly gas-liquid mixed in the branch space 104, and then the outflow pipe 102,
It flows to 103 respectively.

の流出管１０２へは少なく流れると言った偏流が生じる
結果、冷媒ａの均等の分流が困難となると言った課題が
ある。However, in this type of flow divider, when the two outflow pipes 102 and 103 are arranged side by side (horizontal), the refrigerant is evenly divided, but as shown in FIG. When the two outflow pipes 102 and 103 are arranged so as to be vertically arranged, the liquid phase a2, which is heavier than the gas phase a1, flows into the lower outflow pipe 103 due to the influence of gravity, and the upper outflow pipe 103 flows. There is a problem that it becomes difficult to evenly divide the refrigerant a as a result of the uneven flow that flows to the pipe 102 in a small amount.
【０００５】このような冷媒ａの偏流を防止し、均等な

等に分流させることができる。As a means for preventing such a non-uniform flow of the refrigerant a and realizing a uniform flow distribution, for example, the one shown in FIG. 8 has been proposed (Japanese Patent Laid-Open No. 1-121667). In the flow divider shown in FIG. 8, the central axis of the inflow pipe 201 is eccentric from the intermediate position between the two outflow pipes 202 and 203.
Therefore, the shunts are arranged horizontally and the two outflow pipes 202,
When the 203 are arranged vertically, the refrigerant a (in particular, the liquid phase a2) tends to flow downward due to the influence of gravity.
Can be uniformly divided by adjusting the eccentricity of the inflow pipe 201.

Therefore, it is necessary to design by adjusting the eccentricity amount for each model of the air conditioner or even for the same model, for each location where the shunt is used, and to manufacture the shunt with the eccentricity corresponding thereto.
In addition, the angle at which the shunt is arranged varies depending on the model, and the same model may have a different angle depending on the location where the shunt is used. In this case, if the angle at which the shunt is arranged changes, the effect of gravity will naturally also differ.As a result, a design that adjusts the amount of eccentricity will be made for each location where the shunt is used, and the shunt with the eccentricity will be adjusted accordingly. It is necessary to manufacture a container. At that time, the inflow pipe 201 and the outflow pipes 202, 20
3 can be shared even if the models are different, but the branch spaces 204 that determine the amount of eccentricity must be manufactured in different shapes.

The flow rate of the refrigerant a to each outflow pipe 302, 303 is adjusted (Japanese Patent Laid-Open No. 3-105276). In this flow divider, the flow dividing amount can be adjusted by exchanging the orifice, and even in the production stage, the flow divider main body 300 can be shared by preparing a plurality of types of orifices.

Refrigerant a (gas phase and liquid phase) that tends to flow to the side
Can be divided evenly (or at a predetermined ratio) by adjusting the position of the branching protrusion 5. More specifically, each of the outflow pipes 2 and 3 is formed by the branch protrusion 5.
Besides being able to adjust the opening ratio of the flow path to
Not only the opening ratio can be adjusted, but also the refrigerant a, especially the liquid phase can be directly adjusted. That is, when the branching protrusion 5 is provided on the inner wall surface of the branch space 4 facing in the inflow direction from the inflow pipe 1, the refrigerant a, particularly the liquid phase, that has flowed into the branch space 4 is branched. It hits the projecting protrusion 5 and is distributed to any of the outflow pipes 2 and 3 depending on the hit position. Therefore, by adjusting and arranging the branching protrusion 5 at an appropriate position or shape, it is possible to divide the flow into a predetermined ratio, for example, to divide the flow evenly in the vertical direction. Further, when the branching protrusion 5a is provided on the inner wall surface provided with the inflow pipe 1, the liquid phase is temporarily retained in the branching protrusion 5 to adjust the liquid phase.

That is, the tip portion 5 of the branching projection 5 that is the starting point of branching
4 is arranged at a position below the central axis of the inflow pipe 1. As a result, the refrigerant a (vapor phase and liquid phase), which tends to flow downward much due to the influence of gravity, is made uniform (or a predetermined ratio) by adjusting the position of the branching protrusion 5.
Can be shunted. More specifically, the branching protrusion 5 can adjust the opening ratio of the flow path to the first and second outflow openings 21 and 31, and not only adjust the opening ratio but also the refrigerant a, especially the liquid. A direct adjustment to the phase is possible. That is, the refrigerant a, especially the liquid phase, hits the first branch surface 51 above the tip portion 54 of the branching projection 5 and ascends to flow out to the first outflow pipe 2 through the first outflow opening 21. Then, what hits the lower second branch surface 52 descends and is guided so as to flow out to the second outflow pipe 3 via the second outflow opening 31. Therefore, the tip 54
Is flowing on the central axis of the inflow pipe 1 due to the influence of gravity, the tip 54 is asymmetrical or deviated from the central axis of the inflow pipe 1 in this embodiment. For example, it can be adjusted so as to divide the flow evenly in the vertical direction.

However, in addition to the case of being completely in the upper and lower positions, it may be arranged in a slanted state. Further, the central axis may be arranged so as to be inclined. Furthermore, even when the mounting angle is as shown in FIG. 1, there is a case where the ratio of the split flow to the first and second outflow openings 21 and 31 is not equal, and it is required to flow out at a constant ratio. . In such a case, the tip 54 may be symmetrical with respect to the central axis of the inflow pipe 1 and not displaced. The tip 54 of the branching projection 5 may be located on the central axis, or the branching surfaces 51, 52 may be asymmetric in shape. Conversely, the tip 54 of the branching projection 5 may be located on the central axis. Instead, the branch surfaces 51 and 52 may have symmetrical shapes.

のである。As described above, it is necessary to change the shape and position of the branching protrusion 5 to various ones to adjust the flow dividing ratio. However, in the present application, it is not necessary to change the entire flow divider. For example, as shown in FIG. 3 (B), even if the branching projection 5 is changed to a different shape, or the branching projection 5 having the same shape is used, its mounting position (the central axis of the inflow pipe 1 is It is sufficient to change the amount of deviation relative to. Therefore, in the design and production of the flow divider, all other components of the flow divider can be shared, and it is sufficient to prepare the components having different shapes only for the branching protrusion 5, and if the mounting position is adjusted. The branching projection 5 itself can also be used in common, and many types of flow distributors can be manufactured only by changing the assembly position. In particular, when designing a shunt, it is not enough to use only a computational design, and it is necessary to actually attach the prototype to an air conditioner or a refrigerating machine to set optimal conditions. In that case, in the present application, the protrusion 5 for branching is used.
Only by changing part of the shape or adjusting the mounting position, the prototype can be adjusted and changed in a short time, and it is possible to quickly respond to the needs of the user.
