Description

Technical Field

[0001] This utility model belongs to the field of liquid distributor technology, and in particular relates to a modular air conditioning liquid distributor. Background Technology

[0002] The refrigerant distributor in an air conditioning system is a key component. Its main function is to evenly distribute the gas-liquid mixture of refrigerant, after being throttled by the expansion valve, to each branch of the evaporator, ensuring consistent heat exchange efficiency. Its core function is to optimize refrigerant distribution, preventing localized overcooling or overheating of the evaporator and improving system energy efficiency. Existing liquid distributors, such as the assembled air conditioning liquid distributor disclosed in announcement number CN219454332U, include a conical head body. Although the above products make it easy to remove the filter screen during use, the filter screen is prone to local clogging. After clogging, the dispersion effect of the medium is affected. Therefore, an assembled air conditioning liquid distributor is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a prefabricated air conditioning distributor that solves the existing technical problems.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A prefabricated air conditioning distributor includes: a distributor head and a distributor tube, wherein the distributor head and the distributor tube are detachably disposed, one end of the distributor head is provided with an inwardly extending annular limiting part, and the distributor tube is inserted into the distributor head and a filter element is disposed between the distributor head and the limiting part. The filter element includes a positioning ring located between the distributor tube and the limiting part. A filter screen and a porous plate are fixedly connected to the inner wall of the positioning ring. The filter screen is close to the distributor tube to filter impurities, and the porous plate is close to the limiting part to distribute the medium. The medium is dispersed by the filter screen and the porous plate in the filter element, thereby improving its dispersion effect. Even if the filter screen is partially blocked, the medium can still enter the distributor head evenly.

[0005] In one possible design, a second sealing ring is provided at both ends of the positioning ring, and the two second sealing rings abut against the end of the limiting part and the end of the dispensing tube, respectively.

[0006] In one possible design, the distributor head has a flow-dividing cavity inside. The diameter of the flow-dividing cavity near one end of the distributor tube is smaller than that of the other end and is gradually reduced. By setting the flow-dividing cavity inside the distributor head, when the medium enters the flow-dividing cavity, the flow rate can be reduced and its uniform distribution can be promoted due to the different diameters and gradual reduction at both ends of the flow-dividing cavity.

[0007] In one possible design, the end of the dispenser head away from the dispenser tube is provided with multiple diversion holes, which are connected to the diversion cavity and are evenly distributed in a ring.

[0008] In one possible design, a diverter column is fixedly connected to the inner wall of one end of the distributor head, and the end of the diverter column near the distributor tube is tapered.

[0009] In one possible design, a fixing cap is circumferentially fitted onto the separator tube, and an outwardly extending annular fixing part is integrally formed on the circumference of the separator tube. The fixing cap is threadedly connected to the separator head and the separator tube is fixed through the fixing part. A first sealing ring is adhered to the inner wall of one end of the fixing cap to seal the separator head and the separator tube.

[0010] In one possible design, a regulating valve is installed at one end of the distributor tube.

[0011] In this application, a second sealing ring is provided on both sides of the positioning ring and placed into the dispenser head. It is limited by the limiting part. Then, the dispenser tube is inserted into the dispenser head. The fixing cap is rotated to connect and fix the dispenser tube to the dispenser head. After the fixing cap is locked, the connection between the two is sealed by the first sealing ring and the second sealing ring to prevent leakage. When the medium passes through the filter screen, impurities are filtered out. After passing through the perforated plate, the medium is further distributed. Even if the filter screen is partially blocked, the medium can still enter the distributor head evenly, improving the medium dispersion effect. When the medium enters the distribution chamber, the flow rate is reduced and the medium is further evenly distributed due to the different diameters and gradual setting at both ends of the distribution chamber.

[0012] The embodiments of this utility model have the following beneficial effects: In this invention, by installing a filter element between the dispenser head and the dispenser tube, the medium is dispersed through the filter screen and porous plate in the filter element, thereby improving the dispersion effect. Even when the filter screen is partially blocked, the medium can still enter the dispenser head evenly. In this invention, by setting a flow-dividing cavity inside the distributor head, when the medium enters the flow-dividing cavity, the flow rate can be reduced and its uniform distribution can be promoted due to the different diameters and gradual setting at both ends of the flow-dividing cavity. In this invention, the medium is dispersed by the filter screen and porous plate in the filter element, thereby improving the dispersion effect. Even when the filter screen is partially blocked, the medium can still enter the distributor head evenly. At the same time, the diameters at both ends of the distribution chamber are different and gradually set, which can reduce the flow rate and promote its re-distribution evenly.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0021] In one embodiment: Please refer to Figures 1-3 As shown, this embodiment provides a prefabricated air conditioning distributor, including: a distributor head 1 and a distributor tube 2. The distributor head 1 and the distributor tube 2 are detachably disposed. One end of the distributor head 1 is provided with an inwardly extending annular limiting part 15. The distributor tube 2 is inserted into the distributor head 1 and a filter element 6 is disposed between it and the limiting part 15. The limiting part 15 limits the filter element 6 and the distributor tube 2, which facilitates the connection between the distributor head 1 and the distributor tube 2. The filter element 6 includes a positioning ring 11, which is located between the distributor tube 2 and the limiting part 15. The inner wall of the positioning ring 11 is fixedly connected to a filter screen 12 and a porous plate 13. The filter screen 12 is close to the distributor tube 2 to filter impurities, and the porous plate 13 is close to the limiting part 15 to distribute the medium. When the medium passes through the filter screen 12, the impurities in it are filtered by the filter screen 12. After passing through the porous plate 13, the medium can be distributed a second time. Even if the filter screen 12 is partially blocked, the medium can still enter the distributor head 1 evenly, improving the medium dispersion effect.

[0022] The positioning ring 11 is provided with a second sealing ring 14 at both ends. The two second sealing rings 14 abut against the ends of the limiting part 15 and the dispensing tube 2, respectively, and seal the limiting part 15 and the dispensing tube 2 through the second sealing rings 14 to prevent leakage.
