Technical Field
[0001] This utility model relates to the field of air conditioning accessories technology, and in particular to a refrigerant distributor. Background Technology
[0002] An air conditioning distributor, also known as a liquid distributor, refrigerant distributor, or liquid dispenser, is a refrigerant distribution device. The refrigerant passes through an expansion valve or capillary tube for throttling, then exits from the main unit and connects to the distributor. The distributor guides the refrigerant evenly into the connecting pipe at its lower end. Existing air conditioning distributors are mostly cylindrical castings with a liquid inlet at one end and several outlets connected to the inlet at intervals around the other end. These distributors are relatively thick, making them unsuitable for use in confined spaces, and their media distribution uniformity is poor, indicating room for improvement. Utility Model Content
[0003] The present invention aims to overcome the defects in the prior art by providing a refrigerant distributor, which is composed of two plates joined together. It is relatively thin and suitable for use in confined spaces. At the same time, the distributor divides the medium through at least two distribution-convergence methods, which effectively improves the uniformity of medium distribution. Furthermore, this structure gives the distributor better pressure resistance.
[0004] To achieve the above objectives, this utility model provides a refrigerant distributor, including a distributor body, an inlet pipe and several outlet pipes connected to the distributor body, wherein the distributor body has an internal distribution channel for diverting the medium flowing in from the inlet pipe to the several outlet pipes. The main body of the distributor is formed by the joining of a first plate and a second plate. The surface of the first plate facing the second plate is provided with a first groove extending from one side to the other side. The surface of the second plate facing the first plate is provided with a corresponding second groove that cooperates with the first groove to form a distribution channel. The distribution channel includes an inlet section connected to the inlet pipe, a plurality of outlet sections connected one-to-one with the outlet pipe, and a flow equalization section connecting the inlet section and the outlet section. The flow equalization section includes at least two distribution sections arranged at intervals and a plurality of connecting sections connecting two adjacent distribution sections.
[0005] The design is further configured such that the first groove structure on the first plate and the second groove structure on the second plate are symmetrical.
[0006] The design is further configured such that the inlet portion of the first groove has a semi-circular cross-sectional shape, and the inlet portion of the second groove also has a semi-circular cross-sectional shape. The inlet portions of the first and second grooves cooperate to form an inlet portion with a circular cross-section, and the liquid inlet pipe is inserted into the inlet portion and the two are welded together.
[0007] The design is further configured such that the cross-sectional shape of the outlet portion of the first groove is semi-circular, and the cross-sectional shape of the outlet portion of the second groove is also semi-circular. The outlet portions of the first groove and the outlet portions of the second groove cooperate to form an outlet portion with a circular cross-section. The liquid outlet pipe is inserted into the outlet portion and the two are welded together.
[0008] The following configuration is further provided: a first flange is provided on the side of the first plate corresponding to the inflow and / or outflow of the medium, a second flange is provided on the corresponding side of the second plate, and a mating ring for abutting against the flange is provided on the inlet pipe and / or outlet pipe.
[0009] The design further includes: both the first plate and the second plate are made of stainless steel and the grooves thereon are formed by stamping.
[0010] Further configuration: Both the inlet and outlet pipes are made of copper.
[0011] Compared with the prior art, the present invention has a reasonable and compact structure. The distributor is composed of two plates joined together, and is relatively thin, making it suitable for use in confined spaces.

[0014] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.
[0015] This utility model relates to a refrigerant distributor, such as... Figure 1 and Figure 2As shown, it includes a distributor body 10, an inlet pipe 20 and several outlet pipes 30 connected to the distributor body 10, wherein the distributor body 10 is internally configured with a distribution channel 13 for diverting the medium flowing in from the inlet pipe 20 to the several outlet pipes 30.
[0016] In this embodiment, as Figure 1 and Figure 2 As shown, the dispenser body 10 is formed by the mating of a first plate 11 and a second plate 12. The first plate 11 is made of stainless steel, and its surface facing the second plate 12 has a first groove 111 formed by stamping, extending from one side (upper end) to the other side (lower end). The second plate 12 is also made of stainless steel, and its surface facing the first plate 11 has a second groove 121 corresponding to the first groove 111 formed by stamping. The first plate 11 and the second plate 12 are welded together, and the first groove 111 and the second groove 121 between them form a dispensing channel 13. This dispensing channel 13 specifically includes an inlet section 131 connected to the inlet connector 20, and several outlet sections corresponding to the outlet connectors 30. The distributor includes a dry outlet section 132 and a flow equalization section 133 connecting the inlet section 131 and the outlet section 132. The flow equalization section 133 includes at least two spaced distribution sections 1331 and several connecting sections 1332 connected between two adjacent distribution sections 1331. Thus, the flow path of the medium in the distributor is: inlet pipe 20 → inlet section 131 → flow equalization section 133 (distribution section 1331 → connecting section 1332 → distribution section 1331...) → outlet section 132 → outlet pipe 30. In this way, the medium is divided in the flow equalization section 133 through at least two distribution-collection methods, which effectively improves the uniformity of the medium distribution in the distributor. Moreover, this structure gives the distributor better pressure resistance and can withstand higher hydraulic pressure.
[0017] In this embodiment, as Figure 2As shown, the first groove 111 on the first plate 11 and the second groove 121 on the second plate 12 are symmetrical structures. Simultaneously, the cross-sectional shape of the inlet portion of the first groove 111 is semi-circular, and the cross-sectional shape of the inlet portion of the second groove 121 is also semi-circular. Thus, the inlet portions of the first groove 111 and the second groove 121 cooperate to form a circular cross-section inlet portion that matches the liquid inlet connector 20, allowing the liquid inlet connector 20 to be reliably installed within the inlet portion by welding. Similarly, the cross-sectional shape of the outlet portion of the first groove 111 is semi-circular, and the cross-sectional shape of the outlet portion of the second groove 121 is also semi-circular. Thus, the outlet portions of the first groove 111 and the second groove 121 cooperate to form a circular cross-section outlet portion that matches the liquid outlet connector 30, allowing the liquid outlet connector 30 to be reliably installed within the outlet portion by welding.
[0018] In the above scheme, such as Figure 2 As shown, the first plate 11 is provided with a first flange 112 on the side (upper end) where the medium flows in and / or the side (lower end) where it flows out, and the second plate 12 is provided with a second flange 122 on the corresponding side. The corresponding inlet pipe 20 and / or outlet pipe 30 are provided with a mating ring 31 for abutting against the flange. In this way, the mating ring 31 and the flange can not only limit the length of the pipe inserted into the distributor body 10, but also increase the welding area, thereby improving the connection strength and reliability between the pipe and the distributor body 10.
[0019] In this embodiment, both the liquid inlet pipe 20 and the liquid outlet pipe 30 are made of copper, preferably red copper, which facilitates the connection of the pipes to the pipes of other components inside the air conditioner.
[0020] Compared with the prior art, the present invention has a reasonable and compact structure. The distributor is composed of two plates joined together, and is relatively thin, making it suitable for use in confined spaces. At the same time, the distributor divides the flow through at least two diversion-convergence methods, which effectively improves the uniformity of medium distribution. Furthermore, this structure gives the distributor better pressure resistance.
[0021] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
