As shown in fig. 1-4, the diverter 100 of the present application includes a diverter body 101 and an impeller 102. The liquid separator body 101 is internally provided with a main runner 103 and a plurality of sub-runners 104 communicated with the main runner 103, the impeller 102 is arranged at the interface of the main runner 103 and the sub-runners 104, the gas-liquid two-phase refrigerant flows into the main runner 103, and flows into each sub-runner 104 through the interface of the main runner 103 and the sub-runner 104.

The blades can enable the gas-liquid two-phase refrigerant to be decomposed into small-volume bubbles or liquid bubbles through gaps in the blades when flowing through the blades, and the uniformity of mixing of the two-phase refrigerant is improved.

In the present embodiment, the distributor body 101 includes a portion forming the main flow passage 103 and a portion forming the branch flow passage 104, wherein the main flow passage 103 is changed from a small diameter cylinder to a large diameter cylinder in the two-phase refrigerant flow direction through an arc surface having one end recessed, the portion of the main flow passage 103 having a larger diameter is communicated with the plurality of branch flow passages 104, the plurality of branch flow passages 104 are arranged in the circumferential direction of the central axis of the distributor body 101, and the hub of the impeller is disposed on a portion of the branch flow passage 104 surrounding the central axis of the formed distributor body 101, so that the impeller 102 is disposed at the interface of the main flow passage 103 and the branch flow passage 104. The sub-channel 104 is in a stepped cylindrical shape, the diameter of a cylinder communicated with the main channel is smaller, and the diameter of the cylinder at the other end is larger.

In this exemplary embodiment, the dispenser proposed in the present application is described as being applied to a refrigeration system as an example. Those skilled in the art will readily appreciate that numerous modifications, additions, substitutions, deletions, or other changes may be made to the specific embodiments described below in order to adapt the relevant designs of the present application to other types of systems requiring dispensing, and such changes remain within the principles of the dispensers presented herein.

Fig. 5 to 8 show the structure of an impeller of a dispenser of the present application, the impeller 102 comprising a hub 1021 and a plurality of blades 1022, the plurality of blades 1022 being fixedly mounted on the hub, the blades 1022 being substantially S-shaped in cross section. The blades 1022 extend from the hub 1021 in a direction away from the hub 1021, and the cross section of the blades refers to a plane perpendicular to the direction of extension of the blades. The axial hub 1021 and the blades 1022 may be made of metal or non-metal, but are preferably made of engineering plastics, nylon, PPS, PVC, etc., and are required to have a certain strength. In this embodiment the mounting direction of the blades 1022 on the hub 1021 is clockwise, and in other embodiments the mounting direction of the blades 1022 on the hub 1021 is counter-clockwise (as shown in fig. 9).

The hub 1021 and the blades 1022 are formed by separate processes, and then the blades 1022 are fixed to the hub 1021 by welding or adhesion. The number of blades is usually 4-12, preferably 6-10, and in this embodiment the number of blades is 8, uniformly arranged on the hub, or unevenly arranged, but a certain space is ensured between each blade so that the refrigerant can pass through, and the balance performance of the impeller itself is also considered. The S-shaped blade can enhance the liquid separating effect of the liquid separator, and has a simple structure and is convenient to process.

Fig. 10 to 13 show the structure of a vane of a first shape adopted by the impeller of the dispenser of the present application, wherein the cross section of the vane 1022 is two tangential semi-ellipses, which are generally S-shaped, respectively a first semi-ellipse 10221 and a second semi-ellipse 10222, the long axes of the two semi-ellipses being on a straight line. Because the elliptic curve is described by a special equation in the space configuration curve and the outline equation is simple, the two semi-ellipses are tangential to be used as the cross section shape of the blade, so that a good liquid separation effect in a small space range can be realized, the uniformity of the two-phase refrigerant is improved, the die can be simplified, and the cost is reduced.

In this embodiment, the major axes of the two semi-ellipses are equal and centered about the tangent point, i.e., the first semi-ellipse 10221 is congruent with the second semi-ellipse 10222. The adoption of congruence is to facilitate standardized processing and reduce cost. In the present embodiment, the length ratio of the major axis and the minor axis of the first semi-ellipse 10221 and the second semi-ellipse 10222 is 4:1 to 2:1, for example: the major axis of both semi-ellipses is 4mm, then the minor axis may be 1mm to 2mm; the major axis of both semi-ellipses is 2mm and the minor axis may be 0.5mm to 1mm. In this embodiment, the major axis of the first semi-ellipse 10221 and the second semi-ellipse 10222 is specifically selected to be 2mm, and the minor axis thereof is selected to be 1mm. Other semi-ellipses with ratio ranges of major axis to minor axis can not meet the requirement of uniformity of mixing of two-phase refrigerant.

In the present embodiment, the thickness of the blade 1022 is 0.1mm or more and 1/4 or less of the short axis length of the semi-ellipse (first semi-ellipse or second semi-ellipse). The thickness of the blade needs to be selected by considering factors such as the service life, reliability, strength, weight of the blade, and the like, the blade is easy to deform if the thickness is too thin, the service life of the blade is short and unreliable, the weight of the blade is heavier if the thickness is too thick, the waste of materials is easy to cause, and the cost is not beneficial to be reduced. For example, when the minor axis of the semi-ellipse is 2mm, the maximum value of the blade thickness is 0.5mm; when the minor axis of the semi-ellipse is 1mm, the maximum value of the blade thickness is 0.25mm. The thickness of the blade is specifically chosen to be 0.2mm in this embodiment.

As shown in fig. 14, the impeller of the dispenser of the present application adopts a second-shaped blade structure, wherein the cross section of the blade 1022 is generally S-shaped, and is two tangent semi-ellipses, namely a first semi-ellipse 10221 and a second semi-ellipse 10222, and the long axes of the two semi-ellipses are on a straight line. Because the elliptic curve is described by a special equation in the space configuration curve and the outline equation is simple, the two semi-ellipses are tangential to be used as the cross section shape of the blade, so that a good liquid separation effect in a small space range can be realized, the uniformity of the two-phase refrigerant is improved, the die can be simplified, and the cost is reduced. In this embodiment, the major axes of the two semi-ellipses are not equal, i.e., the first semi-ellipse 10221 is not equal to the second semi-ellipse 10222, wherein the major axis of the first semi-ellipse 10221 is greater than the major axis of the second semi-ellipse 10222, and in other embodiments, the major axis of the first semi-ellipse 10221 is less than the major axis of the second semi-ellipse 10222.

In this embodiment, the length ratio of the major axis and the minor axis of the first semi-ellipse 10221 is 4:1 to 2:1, for example: the major axis of the first semi-ellipse is 2mm, then the minor axis may be 0.5 to 1mm; the major axis of the first semi-ellipse is 1mm and the minor axis may then be 0.25 to 0.5mm. The length ratio of the major axis to the minor axis of the second semi-ellipse 10222 is 4:1 to 2:1, for example: the major axis of the second semi-ellipse is 2mm, then the minor axis may be 0.5 to 1mm; the major axis of the second semi-ellipse is 1mm and the minor axis may then be 0.25 to 0.5mm. Other semi-ellipses with ratio ranges of major axis to minor axis can not meet the requirement of uniformity of mixing of two-phase refrigerant. The above options require ensuring that the major axis of the first semi-ellipse is larger than the major axis of the second semi-ellipse. In other embodiments, the above-described selection ranges still apply, except that it is necessary to ensure that the major axis of the first semi-ellipse is smaller than the major axis of the second semi-ellipse.

In this embodiment, the thickness of the blade is greater than or equal to 0.1mm and less than or equal to 1/4 of the length of the minor axis of the minor semi-ellipse of the two tangential semi-ellipses. For example, when the minor axis of the minor one of the two tangential semi-ellipses is 2mm, the maximum value of the blade thickness is 0.5mm; when the minor axis of the half ellipse with the small major axis of the two tangential half ellipses is 1mm, the maximum value of the blade thickness is 0.25mm. The thickness of the blade is specifically chosen to be 0.2mm in this embodiment. The thickness of the blade is selected by considering the factors such as service life, reliability, strength, weight of the blade, and the like, the blade is easy to deform if the blade is too thin, the service life of the blade is short, the blade is unreliable, the weight of the blade is heavy if the blade is too thick, and materials are wasted.

The material of the blade in the above embodiment may be metal or nonmetal, preferably engineering plastic, or nylon, PPS, PVC, or other materials with a certain strength.

The blade 1022 is secured in the mounting slot 1502 by a welding or bonding process or the like. The hub may be metallic or non-metallic, preferably engineering plastic, or nylon, PPS, PVC, or the like. The first end 1503 of the hub 1021 is a rounded convex surface that increases in size from the first end to the second end. The impact of the refrigerant on the hub can be reduced, and the refrigerant can be uniformly distributed among blades around the hub. The second end 1504 of the hub 1021 may be a boss or a cylindrical table, and is mainly used for fixing the hub and the dispenser body, and may be glued, welded, or the like. In other embodiments, the second end 1504 of the hub 1021 may be an external threaded post, and an internal threaded hole needs to be provided at a proper position in the dispenser body 101, so that the second end 1504 of the hub 1021 is fixed in the reserved threaded hole in the dispenser body 101 by a threaded fit to fix the hub and the dispenser body.

In this embodiment, the shape of the slot of the hub mounting slot 1502 corresponds to the cross-sectional shape of the blade 1022 with the major axis of the first semi-ellipse 10221 being greater than the major axis of the second semi-ellipse 10222. In other embodiments, the shape of the slot of the mounting slot 1502 of the hub corresponds to the cross-sectional shape of the blade 1022 with the major axis of the first semi-ellipse 10221 being smaller than the major axis of the second semi-ellipse 10222.
