As shown in fig. 1 to 4, the flow divider 100 of the present application includes a dispenser body 101 and an impeller 102. A main flow passage 103 and a plurality of branch flow passages 104 communicated with the main flow passage 103 are arranged in the liquid distributor body 101, the impeller 102 is arranged at the interface between the main flow passage 103 and the branch flow passages 104, and gas-liquid two-phase refrigerant flows into the main flow passage 103 and flows into each branch flow passage 104 through the interface between the main flow passage 103 and the branch flow passages 104.

In the exemplary embodiment, the liquid distributor 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 design of the present application to other types of systems requiring liquid separation, and such changes are within the scope of the principles of the liquid dispenser as set forth herein.

Fig. 5 to 8 show the structure of the impeller of the liquid distributor 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 blade 1022 extends from the hub 1021 in a direction away from the hub 1021, the cross-section of the blade referring to a plane perpendicular to the direction of extension of the blade. The material of the axial hub 1021 and the blades 1022 may be metal or non-metal, but need to be consistent, and preferably engineering plastics, nylon, PPS, PVC, etc. need to have certain strength. In this embodiment, the blades 1022 are mounted on the hub 1021 in a clockwise direction, and in other embodiments, the blades 1022 are mounted on the hub 1021 in a counterclockwise direction (as viewed in FIG. 9).

The hub 1021 and the blades 1022 are separately formed, and then the blades 1022 are fixed to the hub 1021 by welding or by gluing. The number of blades is generally 4-12, preferably 6-10, in this embodiment 8, uniformly arranged on the hub, or not uniformly arranged, but to ensure that there is a certain space between each blade for the refrigerant to pass through, and also to take into account the balancing properties of the impeller itself. Adopt S type blade can strengthen knockout' S branch liquid effect to simple structure is convenient for process.

Fig. 10 to 13 show a first type of vane configuration for the impeller of the liquid distributor of the present application, in which the cross-section of the vane 1022 is two tangential semi-ellipses, roughly S-shaped, and respectively a first semi-ellipse 10221 and a second semi-ellipse 10222, the major axes of the two semi-ellipses being aligned. Because the elliptic curve has a special equation in a space configuration curve for description and the contour line equation is simple, two semiellipses are tangent to each other to be used as the section shape of the blade, so that a good liquid separation effect in a small space range can be realized, the uniformity of a two-phase refrigerant is improved, a mold can be simplified, and the cost is reduced.

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

In the present embodiment, the thickness of the vane 1022 is equal to or greater than 0.1mm and equal to or less than 1/4 of the minor axis length of the semi-ellipse (first semi-ellipse or second semi-ellipse). The selection of blade thickness needs factors such as considering blade life, reliability, intensity and blade weight, and too thin then the blade is easy to be out of shape, and the blade life-span is short, and is unreliable, and too thick then blade weight is heavier, causes the waste of material easily, is unfavorable for reduce cost. For example, when the minor axis of the semi-ellipse is 2mm, the maximum value of the blade thickness is 0.5 mm; when the minor axis of the semi-ellipse is 1mm, the maximum value of the blade thickness is 0.25 mm. The thickness of the blade is specifically selected to be 0.2mm in this embodiment.

As shown in fig. 14, the impeller of the liquid distributor of the present application adopts a second-shaped blade structure, in which the cross section of the blade 1022 is substantially S-shaped, and is formed by two tangential semi-ellipses, a first semi-ellipse 10221 and a second semi-ellipse 10222, and the major axes of the two semi-ellipses are in a straight line. Because the elliptic curve is described by a special equation in a space configuration curve and the contour line equation is simple, two semiellipses are tangent to form the section shape of the blade, so that a good liquid separation effect in a small space range can be realized, the uniformity of a two-phase refrigerant is improved, the mold can be simplified, and the cost is reduced. In this embodiment, the major axes of the two semi-ellipses are not equal, that is, the first semi-ellipse 10221 and the second semi-ellipse 10222 are not equal, wherein the major axis of the first semi-ellipse 10221 is larger than the major axis of the second semi-ellipse 10222, and in other embodiments, the major axis of the first semi-ellipse 10221 may be smaller than the major axis of the second semi-ellipse 10222.

In this embodiment, the ratio of the length of the major axis to 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 1 mm; the major axis of the first semi-ellipse is 1mm, then the minor axis may be 0.25 to 0.5 mm. The ratio of the length 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 1 mm; the major axis of the second semi-ellipse is 1mm, then the minor axis may be 0.25 to 0.5 mm. Other semi-ellipses with the ratio range of the major axis and the minor axis can not meet the requirement of the mixing uniformity of the two-phase refrigerant. The above selection requires 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 options are still applicable, except that the major axis of the first semi-ellipse is ensured to be smaller than the major axis of the second semi-ellipse.

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

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