Therefore, the liquid dispenser provided by the embodiment can solve the problems of insufficient fluid mixing and poor distribution effect in the prior art.

Specifically, in this embodiment, the liquid chamber 23 may be surrounded by the inflow plate 21, the dividing plate 22 and the inner wall of the cylinder 10, so as to ensure that the fluid can be fully mixed in the liquid chamber 23, and the liquid can flow out from the liquid outlet 221 after mixing.

Or as other embodiments, a connection plate 24 may be provided between the inflow plate 21 and the distribution plate 22, the connection plate 24 having a ring-shaped plate-like structure, and the inflow plate 21 and the distribution plate 22 being respectively installed at both ends of the connection plate 24. The shape of the outer wall of the connection plate 24 is adapted to the shape of the inner wall of the cylinder 10 so that the connection plate 24 is installed in the cylinder 10. By adopting such a structural arrangement, the distribution structure 20 can be conveniently made into a single structure, the disassembly, assembly and adjustment are convenient, the sealing effect of the liquid distribution cavity 23 of the distribution structure 20 is ensured, the liquid distribution cavity 23 is convenient to mix, and the liquid distribution is effectively carried out through the liquid distribution outlet 221 after the mixing. Specifically, the inflow plate 21 and the flow dividing plate 22 may constitute a liquid dividing chamber 23 for fluid mixing, and the liquid dividing chamber 23 is preferably a circular chamber having a flanging hole. The liquid separating cavity 23 is arranged behind the filter screen 30 and in front of the outflow end 12, so that the clean fluid can be ensured to be separated, and the radiator is prevented from being damaged due to the impact of impurities. In addition, the communication cavity 13 may be a rectangular cavity or other cavities with symmetry centers according to different requirements and air conditioner settings. It should be noted here that: the connecting plate 24 and the inflow plate 21, and the dividing plate 22 may be in a split structure, or the connecting plate 24 and the inflow plate 21 may be in an integrated structure, or the connecting plate 24 and the dividing plate 22 may be in an integrated structure.

In this embodiment, the inlet 211 is a circular hole, the inlet plate 21 is a circular plate, and the center of the inlet 211 coincides with the center of the inlet plate 21 (the "center coincidence" herein may allow the center of the inlet 211 and the center of the inlet plate 21 to be within a certain error range). The plurality of liquid separation outlets 221 are provided, the plurality of liquid separation outlets 221 are spatially arranged around the symmetry axis of the inlet 211, and the plurality of liquid separation outlets 221 are equally spaced along the circumferential direction.

Specifically, the plurality of liquid separation outlets 221 is defined as two or more, the inlet 211 is provided at the center of the inlet plate 21, and may be provided concentric with the inlet plate 21 (here, concentric circle arrangement includes concentric circle arrangement within a tolerance allowable range, "concentric circle arrangement" may be understood as that the center of the inlet 211 coincides with the center of the inlet plate 21), the plurality of liquid separation outlets 221 are spatially arranged around the symmetry axis of the inlet 211, and the plurality of liquid separation outlets 221 are arranged at equal intervals in the circumferential direction. With such a configuration, it is ensured that the fluid flowing through the inlet 211 can uniformly flow through the liquid separating outlet 221 to the outlet 12, so as to uniformly separate the liquid from the fluid, and enhance the flow performance of the fluid, thereby enhancing the working efficiency of the air conditioning system.

In this embodiment, the inlet 211 is a first flanging opening, and the flanging of the first flanging opening extends along the direction from the inlet 211 to the liquid separating outlet 221, and the flanging of the first flanging opening is disposed on one side of the inlet plate 21 close to the separating plate 22, or the flanging is located in the liquid separating cavity 23. With the arrangement, a guide channel can be provided for the fluid through the flanging of the first flanging opening, so that the fluid can be conveniently guided to a preset position.

Specifically, when the number of the liquid separating outlets 221 is plural, the liquid separating outlets 221 are symmetrically arranged with the symmetry center of the inlet 211, so that the flange of the first flange directs the fluid to the plate surface of the flow dividing plate 22 between the liquid separating outlets 221 and collides, the fluid bounces back into the liquid separating cavity 23 after colliding and can rebound with the plate surface of the inlet plate 21 again, and the fluid is collided and rebounded for a plurality of times, so that the mixing uniformity of the liquid separating cavity 23 is improved better, and the uniform liquid separation of the fluid is realized better. In addition, the flanging of the first flanging opening is equivalent to providing an accelerating channel, so that the flow velocity of the fluid entering the liquid separating cavity 23 is increased, the impact and rebound of the fluid are improved, and the mixing uniformity is improved.

Specifically, the liquid separating outlet 221 is a second flanging opening, and the flanging of the second flanging opening extends along the direction from the inlet 211 to the liquid separating outlet 221, and the flanging of the second flanging opening is disposed on one side of the flow dividing plate 22 away from the inlet 21. By adopting the structure, the second flanging opening can be conveniently connected with the pipe fitting to be connected, and the installation is convenient.

Specifically, the first flanging structure of the inlet 211 may be symmetrically arranged along the symmetry center into a plurality according to specific requirements. The radius of the liquid separating outlet 221 is smaller than that of the inlet 211, and the arrangement can increase the flow velocity of the fluid at the liquid separating outlet 221, so that the heat exchange efficiency in the heat exchanger can be improved.

As shown in fig. 2, in the present embodiment, the distance between the inlet plate 21 and the flow dividing plate 22 is L1, the flanging length of the first flanging opening is L2, the radius of the inlet 211 is R1, the radius of the liquid dividing outlet 221 is R2, and the radial distance between the inlet 211 and the liquid dividing outlet 221 is d.

Specifically, the relationship between the above values is as follows:

1/5 is less than or equal to L2/L1 is less than or equal to 1/3, and the arrangement can ensure that the fluid flows out in sufficient space, avoid the condition that the fluid flowing out in the first flanging opening bounces into the first flanging opening due to the too close distance between the flanging of the first flanging opening and the flow dividing plate 22 or avoid the condition that the fluid cannot collide and rebound for many times due to the too far distance between the flanging of the first flanging opening and the flow dividing plate 22, so that the fluid can be fully mixed in the liquid dividing cavity 23.

The arrangement of R2/R1 which is more than or equal to 1/4 and less than or equal to 1/2 can enable the fluid to enter the second flanging hole through the first flanging opening, so that further acceleration is achieved, and the overall working efficiency of the system is further improved.

1/2.Ltoreq.d/R1.ltoreq.2/3, it should be noted that the radial distance between the inlet 211 and the outlet 221 may refer to the distance between the symmetry axis of the inlet 211 and the symmetry axis of the outlet 221, and the outlet 221 is disposed around the inlet 211. By setting the radial distance between the inlet 211 and the liquid separating outlet 221 within the above distance ratio, the liquid flowing out through the inlet 211 can be impacted onto the flow dividing plate 22 and rebound into the liquid separating cavity 23, so that the fluid can be fully mixed in the liquid separating cavity 23, and the mixing uniformity is improved.

In the present embodiment, an inlet pipe 41 is installed at the inflow end 11, and a liquid separation pipe 42 is installed at the liquid separation outlet 221.

Specifically, the dispenser in the present embodiment further includes a filter screen 30, and the filter screen 30 is installed in the communication chamber 13 and is disposed between the inflow end 11 and the distribution structure 20 in the axial direction of the cylinder 10. With such arrangement, by providing the cylinder 10 having the inflow end 11, the outflow end 12 and the communication chamber 13in the dispenser, and providing the distribution structure 20 and the filter screen 30 in the communication chamber 13, the filter screen 30 can filter the fluid flowing into the distribution structure 20, so that the separate arrangement of the dispenser and the filter in the air conditioning system is not required, and the two can be integrated into one body, thereby reducing the space for installation as much as possible.

In this embodiment, the filter screen 30 includes a mounting section 31 and a filter section 32 that are connected to each other. The shape of the mounting section 31 is adapted to the shape of the inner wall of the cylinder 10 forming the communication chamber 13 and conforms to the inner wall of the cylinder 10. Meanwhile, the diameter of the filtering section 32 gradually decreases along the extending direction of the mounting section 31 to the filtering section 32. By adopting the structure, the filter screen 30 and the barrel 10 can be conveniently matched and installed through the installation section 31, and meanwhile, the filter section 32 of the filter screen 30 forms a funnel-shaped structure, so that the filter area can be effectively increased, and the filter effect is enhanced.

In this embodiment, the barrel 10 has a limiting protrusion 14, and along the axial direction of the barrel 10, the limiting protrusion 14 is located on one side of the mounting section 31 away from the inflow end 11, and the limiting protrusion 14 abuts against the filtering section 32 to limit. The spacing protruding 14 is provided to help the barrel 10 to abut against the filter screen 30, and limit the filter screen 30 along the direction from the inflow end 11 to the outflow end 12, so that the filter screen 30 can be prevented from moving in the working process, and the reliability and stability of the liquid dispenser assembly are enhanced.

In this embodiment, the limiting protrusion 14 is formed by recessing from the sidewall of the cylinder 10 into the communication cavity 13 along the radial direction of the cylinder 10. By adopting the arrangement, the limiting structure can be not required to be independently arranged, only the cylinder body 10 is required to be processed and formed, the installation difficulty is reduced, the manufacturing cost is saved, and meanwhile, the hidden danger of stability reduction caused by independently arranging the limiting structure can be avoided due to the integral structure of the limiting bulge 14 and the cylinder body 10.

In this embodiment, the cartridge 10 further comprises a flared section 15 and a liquid separation section 16 connected to each other, the inlet end 11 being formed at the end of the flared section 15 remote from the liquid separation section 16, and the outlet end 12 being formed at the end of the liquid separation section 16 remote from the flared section 15. The mounting section 31 of the filter screen 30 is mounted at the liquid separation section 16. Along the axial direction of the barrel 10 from the inflow end 11 to the outflow end 12, the section diameter of the flaring section 15 is gradually increased, the mounting section 31 of the filter screen 30 is positioned between the limiting boss 14 and the flaring section 15, the mounting section 31 can be abutted with the flaring section 15 to limit the direction of the filter screen 30 from the outflow end 12 to the inflow end 11, namely, the filter screen 30 can be axially limited through the limiting boss 14 and the flaring section 15. Thus, as a further embodiment, a clearance fit between the mounting section 31 and the inner wall of the barrel 10 may also be provided. In addition, with such arrangement, the fluid pressure in the liquid separation section 16 is smaller than the fluid pressure in the flaring section 15, so that the fluid impact force applied to the filter screen 30 is reduced, and meanwhile, the filter screen 30 with a sufficient area is conveniently arranged for full filtration, and the filtering effect is improved.

In a second embodiment of the present invention, there is provided a heat exchanger assembly including: the heat exchanger and the liquid separator provided in the first embodiment are connected with the heat exchanger, so that liquid separation and filtration can be completed before fluid enters the heat exchanger, and meanwhile, the fluid can be accelerated before entering the heat exchanger due to the existence of the flanging hole structure, so that the heat exchange efficiency of the heat exchanger is improved.
