A shunt 100 according to an embodiment of the present utility model is described in detail below in conjunction with fig. 1-8.

Referring to fig. 1-4, a shunt 100 according to an embodiment of the present utility model may include a shunt 1, a shunt 2, and a filter 3. The shunt tube 1 is provided with an inlet 11 and a plurality of spaced shunt ports 12, the shunt tube 1 is used for shunting media, and the media can flow in from the inlet 11 of the shunt tube 1 and then flow out from the plurality of spaced shunt ports 12. Alternatively, the left side of the shunt tube 1 is provided with an inlet 11, the right side is provided with a plurality of shunt ports 12 which are separated, and the number of the shunt ports 12 can be three, four, five, etc.

A flow path is formed from the inlet 11 to the plurality of shunt ports 12, the shunt 2 is disposed on the flow path so that the medium flowing in from the inlet 11 flows out from the plurality of shunt ports 12 through the shunt 2, and the filter 3 is disposed on the flow path so that the medium flowing in from the inlet 11 flows out from the plurality of shunt ports 12 through the filter 3. Thus, the medium flowing out of each of the shunt ports 12 is the medium passing through the shunt member 2 and the filter member 3.

When the medium is in a gas-liquid two-phase state, the medium flowing out through the flow dividing piece 2 can maintain the gas-liquid two-phase state, so that the medium is prevented from being unevenly distributed in the pipe of the flow dividing pipe 1.

By providing the filter member 3, the flow divider 100 has a filtering function, and the integration level of the product is improved. The filter element 3 can filter the impurity in the medium on the one hand, on the other hand is favorable to the medium misce bene, for example when the medium is gas-liquid refrigerant, gas-liquid mixture can mix more evenly through the filter element 3, reduces gas-liquid separation degree, and then reduces the noise that gas-liquid refrigerant produced, improves the reposition of redundant personnel effect.

According to the flow divider disclosed by the embodiment of the utility model, the medium flowing in from the inlet 11 flows out from the plurality of the flow dividing ports 12 after passing through the flow dividing part 2 and the filtering part 3, so that the product integration level is high, and the mixing of gas-liquid refrigerants is facilitated.

In some embodiments, as shown in fig. 1 to 4, the flow dividing member 2 is provided with a flow dividing through hole 21, the flow dividing member 2 is disposed in the flow dividing pipe 1 and the flow dividing member 2 is located between the inflow port 11 and the plurality of flow dividing ports 12, so that the medium flowing from the inflow port 11 flows to the plurality of flow dividing ports 12 through the flow dividing through hole 21. Specifically, the medium flowing from the inlet 11 flows through the flow dividing through holes 21 of the flow dividing member 2 to the plurality of flow dividing holes 12, and the medium flowing from the inlet 11 accelerates to flow out from the flow dividing through holes 21 due to a certain pressure difference between both sides in the thickness direction of the flow dividing through holes 21. For example, when the medium is in a gas-liquid two-phase state, the medium flowing out of the shunt hole 21 can maintain the gas-liquid two-phase state, thereby avoiding uneven distribution of the medium in the tube of the shunt tube 1. Optionally, the flow dividing member 2 is a structure with a flow dividing function, such as a single-hole gasket, a porous gasket, and the like, and one or more flow dividing through holes 21 can be formed in the flow dividing member 2, and the plurality of flow dividing through holes 21 can enable media to be mixed more uniformly.

In some embodiments, as shown in fig. 2 and 3, the plurality of flow dividing through holes 21 includes a first sub-through hole 211 and a plurality of second sub-through holes 212 spaced apart in the circumferential direction of the flow dividing member 2, the first sub-through hole 211 being located at the center of the flow dividing member 2, the cross-section of the first sub-through hole 211 being formed in a circular shape. By providing the plurality of flow dividing through holes 21 on the flow dividing member 2, the medium passing through the flow dividing through holes 21 is accelerated, and the medium is atomized into fine droplets by utilizing the shearing effect of the high-speed gas, so that the medium is uniformly distributed on the flow cross section of the flow dividing pipe 1, and the flow of the medium flowing out from each flow dividing port 12 is uniform. For example, when the medium is in a gas-liquid two-phase state, the flow dividing through hole 21 can accelerate the gas-liquid medium, atomize the liquid into fine liquid drops by utilizing the shearing effect of the high-speed gas, and fully and uniformly mix the gas and the liquid on the flow section under the carrying of the high-speed gas.

In some embodiments, as shown in fig. 2, the second sub-vias 212 are elongated strip-shaped holes. The arrangement can make the accelerating effect of the medium better, and can more fully utilize the shearing effect of the high-speed gas, thereby further enabling the medium to be uniformly distributed on the flow cross section. The shape of the second sub-through hole 212 may be rectangular, racetrack, or the like.

In some embodiments, the second sub-aperture 212 extends in a circumferential or radial direction of the shunt 2. Specifically, as shown in fig. 4, the second sub-through holes 212 may extend in the circumferential direction of the flow splitter 2, wherein the second sub-through holes 212 extend in an arc shape in the circumferential direction of the flow splitter 2, and of course, the second sub-through holes 212 may also extend in the radial direction of the flow splitter 2. The arrangement of the second sub-through holes 212 is more reasonable, so that the accelerating effect of the medium is better, and the shearing effect of high-speed gas can be more fully utilized, so that the medium is uniformly distributed on the flow cross section.

For example, as shown in fig. 2, the second sub-through holes 212 are distributed along the circumferential direction of the flow splitter 2, and the second sub-through holes 212 extend in a straight line, the shape of the cross section of the second sub-through holes 212 is a racetrack shape, and the plurality of second sub-through holes 212 are uniformly spaced apart in the circumferential direction of the flow splitter 2.

The accelerating effect of the medium can be improved, the shearing effect of high-speed gas can be fully utilized, the medium is further uniformly distributed on the flow section, meanwhile, the second sub through holes 212 are round holes, the processing is convenient, and the processing efficiency of the flow dividing piece 2 can be improved.

For example, in the embodiment shown in fig. 3, the second sub-through holes 212 are circular holes, and the plurality of second sub-through holes 212 are uniformly spaced in the circumferential direction of the flow splitter 2.

According to some embodiments of the present utility model, as shown in fig. 3, the plurality of second sub-through holes 212 are a plurality of circles arranged at intervals in the radial direction of the flow splitter 2. This arrangement can increase the flow rate of the medium through the flow divider 2, thereby increasing the flow dividing efficiency of the flow divider 100.

For example, in the embodiment shown in fig. 3, the plurality of second sub-through holes 212 are uniformly distributed in the circumferential direction of the flow splitter 2 and are arranged at intervals of two turns in the radial direction of the flow splitter 2.

Further, in the radial direction of the flow divider 2, the plurality of second sub-through holes 212 of two adjacent turns are staggered. It will be appreciated that the second sub-via 212 of one of the adjacent turns is located between the second sub-via 212 of the other adjacent turn. This can improve the atomizing effect on the medium.
