Abstract
Description
Technical Field
[0001] This utility model relates to a liquid distributor for a refrigeration system. Background Technology
[0002] After being throttled, the refrigerant becomes a gas-liquid two-phase substance and flows into the evaporator. Whether the refrigerant can be evenly and equally distributed to each branch of the evaporator has a crucial impact on the performance of the evaporator and the entire refrigeration system. The distributor is an important auxiliary device that mixes the gas and liquid phases and evenly distributes them to each branch of the evaporator.
[0003] After prolonged use, the separator may become clogged, leading to incomplete evaporation in the distribution branches, which in turn causes frost formation and reduces heat exchange efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide a technical solution for a liquid distributor for a refrigeration system, which addresses the shortcomings of existing technologies. It can effectively clean the various throttling orifices, capillary inlet chambers and capillary welding chambers in the liquid distribution section to prevent blockage. It also facilitates the uniform distribution of the gas-liquid two-phase mixture to each liquid distribution branch, thereby improving the working efficiency of the refrigeration system and extending its service life.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A liquid distributor for a refrigeration system, comprising: Liquid inlet section, which is equipped with a liquid inlet chamber; The liquid separation section is equipped with a homogeneous cavity and several capillary welding cavities. The homogeneous cavity is connected to the liquid inlet cavity, and the capillary welding cavity is connected to the throttling orifice through the capillary inlet cavity. The throttling orifice is connected to the homogeneous cavity. Its features are: It also includes a cleaning mechanism, which comprises a cylinder, a tube body, a receiving head, and a brush. The cylinder is connected to the liquid inlet section via an end cap, the tube body is connected to the end cap and located inside the liquid inlet chamber, and the receiving head is located at the top of the tube body. The receiving head has through holes matching the number of throttling orifices. The cylinder is connected to a push-pull plate via a piston rod. The push-pull plate has elastic rods matching the number of through holes, and the elastic rods are equipped with brushes. The cylinder drives the push-pull plate to move up and down, so that the elastic rods drive the brushes to reciprocate along the throttling orifices, the capillary inlet chamber, and the capillary welding chamber for continuous cleaning. Through the design of the above structure, not only can the various throttling orifices, capillary inlet chambers, and capillary welding chambers in the liquid distribution section be effectively cleaned to prevent blockage, but it also facilitates the uniform distribution of the gas-liquid two-phase mixture to each liquid distribution branch, improving the working efficiency of the refrigeration system and extending its service life.
[0006] Furthermore, a mixing mechanism is rotatably connected to the outer side of the tube body. The mixing mechanism includes a rotating sleeve and blades. The rotating sleeve is rotatably connected to the outer side of the tube body, and the blades are distributed in a ring on the outer side of the rotating sleeve. After the gas and liquid phases enter the liquid inlet chamber, they can drive the blades to rotate, which helps to improve the uniformity of the gas and liquid phase mixing.
[0007] Furthermore, the liquid distribution section and the liquid inlet section are integrally machined, which can improve the processing quality and accuracy of the liquid distributor.
[0008] Furthermore, a sealing ring is provided between the end cap and the liquid inlet section, which can improve the sealing performance between the end cap and the liquid inlet section.
[0009] Furthermore, it also includes at least one liquid inlet, which is arranged along the tangential direction of the liquid inlet section and connected to the liquid inlet chamber, so as to facilitate the rotation of the mixing mechanism and improve the uniformity of gas-liquid mixing.
[0010] Furthermore, the top of the liquid separation section is provided with an inclined surface.
[0011] Furthermore, the inner diameters of the capillary welding cavity, the capillary inlet cavity, and the throttling orifice decrease sequentially.
[0012] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects: This invention can not only effectively clean the various throttling orifices, capillary inlet chambers and capillary welding chambers in the liquid distribution section to prevent blockage, but also facilitate the uniform distribution of the gas-liquid two-phase mixture to each liquid distribution branch, thereby improving the working efficiency of the refrigeration system and extending its service life.

[0018] like Figures 1 to 3 As shown, this utility model discloses a liquid distributor for a refrigeration system, comprising: an inlet section 1 and a dispensing section 2, wherein the inlet section 1 is provided with an inlet chamber 6. The dispensing section 2 and the inlet section 1 are integrally formed, which can improve the processing quality and accuracy of the liquid distributor.
[0019] The liquid separation section 2 is provided with a homogeneous cavity 7 and several capillary welding cavities 10. The homogeneous cavity 7 is connected to the liquid inlet cavity 6. The capillary welding cavity 10 is connected to the throttling orifice 8 through the capillary inlet cavity 9. The throttling orifice 8 is connected to the homogeneous cavity 7.
[0020] The inner diameters of the capillary welding cavity 10, the capillary inlet cavity 9, and the throttling orifice 8 decrease sequentially.
[0021] The top of the liquid separation section 2 is provided with an inclined surface 3, and the capillary welding cavity 10 passes through the inclined surface 3.
[0022] The separator also includes a cleaning mechanism, which includes a cylinder 5, a tube 12, a receiving head 11, and a brush 16. The cylinder 5 is connected to the inlet section 1 through an end cap 18. A sealing ring 19 is provided between the end cap 18 and the inlet section 1. The sealing ring 19 can improve the sealing between the end cap 18 and the inlet section 1.
[0023] The tube body 12 is connected to the end cap 18 and located in the liquid inlet chamber 6. The receiving head 11 is located at the top of the tube body 12. The receiving head 11 has through holes 20 that match the number of throttling orifices 8. The cylinder 5 is connected to the push-pull plate 14 through the piston rod 13. The push-pull plate 14 has elastic rods 15 that match the number of through holes 20. The elastic rods 15 have brushes 16. The cylinder 5 drives the push-pull plate 14 to move up and down, so that the elastic rods 15 drive the brushes 16 to move back and forth along the throttling orifice 8, the capillary inlet chamber 9 and the capillary welding chamber 10 for continuous cleaning.
[0024] A mixing mechanism 17 is rotatably connected to the outer side of the tube body 12. The mixing mechanism 17 includes a rotating sleeve 21 and blades 22. The rotating sleeve 21 is rotatably connected to the outer side of the tube body 12. The blades 22 are distributed in a ring on the outer side of the rotating sleeve 21. After the gas and liquid phases enter the liquid inlet chamber 6, they can drive the blades 22 to rotate, which is beneficial to improving the uniformity of the gas and liquid phase mixing.
[0025] The above-mentioned structural design not only effectively cleans the various throttling orifices 8, capillary inlet 9, and capillary welding chamber 10 in the liquid distribution section 2, preventing blockage, but also facilitates the uniform distribution of the gas-liquid two-phase mixture to each liquid distribution branch, improving the working efficiency of the refrigeration system and extending its service life.
