[0020] Hereinafter, the technical aspects of the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, but it is clear that the described embodiments are merely some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is actually merely explanatory and does not limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As shown in Figures 1 to 4, Example 1 of the present application provides a separator including a separation tube 10 and an impeller 20. Here, the separation tube 10 has a liquid inlet 11, a separation chamber 12, and a plurality of liquid outlets 13, the liquid inlet 11 and the plurality of liquid outlets 13 are all connected to the separation chamber 12, the liquid inlet 11 is located at one end of the separation tube 10, and the plurality of liquid outlets 13 are located at the other end of the separation tube 10. The impeller 20 is provided in the separation chamber 12, and includes a hub 21 and blades 22 provided on the hub 21, and the cross-sectional shape of the blades 22 perpendicular to the extension direction of the blades 22 is elliptical.

[0022] According to the technical aspect provided by the present application, the cross section of the blade 22 is elliptical, which simplifies the structure of the blade 22 and facilitates design and manufacturing. In this manner, the impeller 20 separates the fluid in the separation pipe 10, and not only can the separation effect be ensured, but also the design and manufacturing costs of the blade 22 can be reduced.

[0023] Here, the impeller 20 may be fixed within the separation pipe 10 or may be rotatably provided within the separation pipe 10, and in the present application, the impeller 20 is fixed within the separation pipe 10.

[0024] Specifically, the ratio of the length of the major axis to the length of the minor axis of the elliptical cross section of the impeller 22 is set to between 4:1 and 10:1. In this way, the pressure drop can be reduced while ensuring uniformity of liquid separation. Specifically, the ratio of the length of the major axis to the length of the minor axis may be set to 6:1 or 8:1.

[0025] Here, the blades 22 are inclined on the hub 21, and there is an included angle between the blades 22 and the axis of the hub 21. If the included angle is too large, the pressure drop increases, and if the included angle is too small, the liquid separation effect is poor. In this application, the included angle between the blades 22 and the axis of the hub 21 is set to between 30° and 60°. In this way, not only can the liquid separation effect be ensured, but also the pressure drop can be reduced as much as possible. In this embodiment, the included angle between the blades 22 and the axis of the hub 21 is 45°.

[0026] In this embodiment, the impeller 20 is provided with a plurality of blades 22, and the number of the blades 22 is not less than three, and the number of the blades 22 in the impeller 20 in this application is six or more.

[0027] Here, the wings 22 and the hub 21 may be provided separately, or may be molded as an integral body. By forming the wings 22 and the hub 21 as an integral body, attachment becomes easier.

[0028] Specifically, the impeller 20 is made of plastic. The impeller 20 is made of a plastic material, which has low manufacturing costs and can reduce the weight of the entire device. Specifically, the impeller 20 may be made of polyphenylene sulfide, polyphenylene ether, polyamide, polycarbonate, thermoplastic resin, or polyoxymethylene material.

[0029] In this embodiment, the wings 22 and the hub 21 are provided separately, and it is easy to manufacture these structures separately, which reduces the manufacturing cost of the mold. Also, the side wall of the hub 21 has an attachment groove 211, and one end of the wings 22 is bonded or welded into the attachment groove 211. By providing the attachment groove 211, the connection between the wings 22 and the hub 21 can be strengthened. Specifically, the shape of the attachment groove 211 is matched with the shape of the end of the wings 22. The wings 22 and the hub 21 are connected by an adhesive or welding method, which makes it easy to process them and ensures the strength of the connection between them.

[0030] Here, the hub 21 has a first end and a second end opposite to each other, the first end is disposed toward the liquid inlet 11, and the size of the first end is gradually increased from the first end to the second end, so that the impact of the fluid on the hub 21 can be reduced, and the fluid can be evenly distributed around. The second end of the hub 21 is bonded, welded or screwed to the separation pipe 10. The hub 21 is connected to the separation pipe 10 in the above-mentioned manner, which can facilitate the connection between the two, and is disposed in the separation pipe so as to be rotatable with respect to the impeller, and the present application has a simple structure and low cost.

[0031] 5, Example 2 of the present application provides a separator having multiple impellers 20, which are overlapped in the separating chamber 12, different from Example 1. The above-mentioned structure can improve the separating effect of the separator, so that the fluid is uniformly distributed to each liquid outlet 13.

[0032] Here, the blades 22 of the multiple impellers 20 may be arranged in the same or different directions. By making the arrangement direction of the blades 22 of at least one impeller 20 different from the arrangement direction of the blades 22 of the other impellers 20, the uniformity of liquid separation by the device can be further improved. In this embodiment, two impellers 20 are provided in the liquid separator, and the blades 22 of one impeller 20 are arranged clockwise, and the blades 22 of the other impeller 20 are arranged counterclockwise.

[0033] Here, the two adjacent impellers 20 may be connected by adhesive, welding or screwing, and in this embodiment, the two adjacent impellers 20 are connected by adhesive.

[0034] As shown in FIG. 6, Example 3 of the present application is different from Example 2 in that in the present application, two adjacent impellers 20 are connected by a screwing method, and the end of the hub of the first impeller 20 penetrates the hub of the second impeller 20 and provides a separator that is screwed into the hub of the second impeller 20. The above-mentioned structure makes the connection strong and reliable, and improves the connection strength between the two impellers 20.

[0035] The liquid separator provided by the present application has an elliptical cross section for the blades, which simplifies the structure and reduces manufacturing costs while ensuring the liquid separation effect.The impeller material is made of engineering plastics, which allows the impeller to be manufactured by injection molding, which reduces the molding difficulty and processing cost, reduces the weight of the impeller components, and has higher reliability and application range in the refrigerant system due to the high mechanical lightness and chemical stability of engineering plastics.
