Description

Technical Field

[0001] This utility model belongs to the field of liquid separator technology, and more specifically, it relates to a brass liquid separator with a copper outer shell. Background Technology

[0002] The distributor is an important component in a vapor compression refrigeration cycle system. Its main function is to distribute the refrigerant and ensure that each part receives a uniform supply of refrigerant. The distributor usually includes an inlet pipe and several outlet pipes. After the refrigerant enters the distributor, it is guided to the outlet pipes through the inlet pipe, thereby achieving distribution.

[0003] Existing liquid distributors generally suffer from uneven distribution in practical applications. The internal flow channel design of the liquid distributor is not reasonable enough. After the fluid enters the liquid distributor, due to abrupt changes in the flow channel cross-section and improper bending angles, the flow velocity and flow rate of the fluid at each outlet are significantly different, making it impossible to achieve uniform distribution. This results in inconsistent heat exchange effects of each evaporator, reduces the energy efficiency of the entire refrigeration system, and affects the refrigeration effect.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is a copper-cased, brass-insulated liquid separator, including a liquid separator body. The liquid separator body has a plurality of liquid separator holes evenly distributed around its circumference. A shell is threaded onto the outer circumference of the liquid separator body. An inlet end is provided at the upper end of the shell. The inner diameter of the upper end of the inlet end is smaller than that of the lower end, and it is funnel-shaped. An inlet hole is provided at the upper end of the inlet end. A flow-dividing structure is installed on the liquid separator body. The flow-dividing structure is used to evenly distribute the liquid entering from the inlet hole to each liquid separator hole.

[0006] The upper end of the liquid separator is coaxially provided with an installation groove, and the flow separation structure is detachably installed in the installation groove.

[0007] The diversion structure includes a mounting base, which is set in a mounting groove. A diversion seat is rotatably mounted on the mounting base. The upper diameter of the diversion seat is smaller than the lower diameter, and it is trumpet-shaped. Several diversion baffles are evenly installed on the outer surface of the diversion seat. The diversion baffles are spirally installed, and the outer side of each diversion baffle is in contact with the inner wall of the liquid inlet.

[0008] The inner wall of the housing has an annular groove, and an O-ring is installed in the annular groove.

[0009] A positioning plate is installed inside the liquid inlet, and a filter plate is movably mounted on the positioning plate.

[0010] Both the shell and the liquid inlet are made of copper.

[0011] The separator is made of brass.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model incorporates a funnel-shaped design for the inner wall of the liquid distribution end and the distribution seat, as well as a uniformly spiral-designed distribution baffle. This forces the refrigerant to rotate in a spiral shape after entering the distributor, achieving uniform circumferential distribution through centrifugal force. Combined with the symmetrical layout of the liquid distribution holes, this completely eliminates the flow difference caused by abrupt changes in the flow channel in traditional distributors, ensuring that the refrigerant is evenly distributed to the capillary tube, thereby improving the energy efficiency and cooling effect of the refrigeration system.

[0014] 2. By changing the material of the shell and liquid inlet end from brass to copper, the liquid separator has achieved significant improvements in cost reduction, processing speed, performance, and product weight. The excellent ductility and corrosion resistance of copper make the processing more efficient and the product performance more stable. At the same time, by optimizing the design and processing technology, raw materials are saved and the product is made lighter, which not only reduces production costs but also improves the product's market competitiveness.

[0015] 3. The detachable design of this utility model makes it more convenient to clean, inspect and replace parts. When there is blockage inside the distributor or damage to the parts, the shell and the flow distribution structure can be quickly disassembled for cleaning or replacement, which extends the service life of the distributor and adapts to different refrigerant types and flow requirements.

[0016] 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

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0025] Please see Figures 1-3 As shown:

[0026] This embodiment provides a copper-cased, brass-insulated liquid distributor, including a liquid distributor body 1. The liquid distributor body 1 has a plurality of liquid distributor holes 2 evenly distributed around its circumference, with at least two liquid distributor holes 2. A housing 3 is threaded onto the outer circumferential surface of the liquid distributor body 1. The inner wall of the housing 3 is tightly attached to the outer circumferential surface of the liquid distributor body 1. A liquid inlet end 4 is provided at the upper end of the housing 3. The inner diameter of the upper end of the liquid inlet end 4 is smaller than that of the lower end, and it is funnel-shaped. A liquid inlet hole 5 is provided at the upper end of the liquid inlet end 4. A flow-dividing structure 6 is installed on the liquid distributor body 1. The flow-dividing structure 6 is used to evenly distribute the liquid entering from the liquid inlet hole 5 to each liquid distributor hole 2.

[0027] In practical use, the refrigerant enters the inner cavity of the inlet end 4 through the liquid inlet hole 5. The funnel-shaped design of the liquid inlet end 4 can reduce turbulence and pressure fluctuations caused by direct fluid impact, creating initial conditions for uniform distribution. After entering the liquid inlet end 4, the refrigerant passes through the diversion structure 6 and then enters the diversion hole. The diversion structure 6 optimizes the uniform distribution of the refrigerant, allowing it to be evenly distributed into several liquid distribution holes 2. The refrigerant then flows into several capillary tubes through the liquid distribution holes 2, thereby eliminating the problem of uneven distribution caused by unreasonable flow channel design in traditional liquid distributors. This achieves uniform distribution of refrigerant and improves the overall energy efficiency of the refrigeration system.

[0028] like Figure 3-5As shown, the upper end of the liquid separator 1 is coaxially provided with an installation groove 7. The flow-dividing structure 6 is detachably installed in the installation groove 7. The flow-dividing structure 6 includes an installation seat 8, which is disposed in the installation groove 7. A flow-dividing seat 9 is rotatably installed on the installation seat 8. The upper diameter of the flow-dividing seat 9 is smaller than the lower diameter, and it is funnel-shaped. Several flow-dividing baffles 10 are evenly installed on the outer surface of the flow-dividing seat 9. The flow-dividing baffles 10 are spirally installed, and the outer sides of the flow-dividing baffles 10 are all in contact with the inner wall of the liquid inlet end 4. After the refrigerant enters the liquid separator, it will first come into contact with the funnel-shaped flow-dividing seat. 9. The flared design of the flow divider 9 initially guides the fluid, causing it to diffuse outwards along the surface of the flow divider 9. It is then guided by the spirally arranged flow divider 10 to rotate in a spiral shape. Since the flow divider 10 is evenly distributed and has consistent spiral parameters, the flow distribution of the fluid in the circumferential direction tends to be consistent, so that the refrigerant can be evenly distributed into the liquid distribution hole 2. In addition, the spiral flow divider 10 replaces the abrupt flow channel of the traditional liquid distributor, and the fluid transitions smoothly through the gradual spiral path, avoiding the flow difference caused by abrupt changes in local resistance and achieving uniform distribution of refrigerant.

[0029] like Figure 3 , Figure 6 As shown, a positioning plate 13 is provided inside the liquid inlet 5, and a filter plate 14 is movably arranged on the positioning plate 13. The filter plate 14 can effectively intercept impurities in the fluid, prevent the liquid distribution hole 2 from being blocked and the flow distribution structure 6 from being worn, and significantly improve the reliability of the liquid distributor and the entire refrigeration system.

[0030] like Figure 3 As shown, the shell 3 and the liquid inlet 4 are made of copper, and the liquid separator 1 is made of brass. The shell 3 and the liquid inlet 4 are made of copper, which has the following advantages.

[0031] Reduced labor hours and increased processing efficiency:

[0032] Copper has significantly better ductility than brass, which makes it easier to achieve one-piece molding of complex shapes during processing. Through processes such as stamping, the shell 3 and liquid inlet end 4 can be manufactured in one go, reducing subsequent processing and assembly steps. This not only reduces labor hours but also improves production efficiency and further reduces production costs.

[0033] Performance improvements:

[0034] Copper has a higher density than brass, providing better structural strength and sealing performance. In refrigeration distributors, the high-density copper material can effectively prevent refrigerant leakage and ensure stable system operation.

[0035] Copper exhibits excellent corrosion resistance in various media, particularly in non-oxidizing acid, alkali, and salt solutions. It maintains stable performance even in harsh working environments, thus extending its service life.

[0036] Lightweight advantages:

[0037] The wall thickness of copper can be made as thin as possible within a specified range without affecting product performance. This optimized design makes the copper shell four times lighter than the brass shell, achieving product lightweighting. This not only reduces raw material costs but also facilitates transportation and installation.

[0038] Example 2, as Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown;

[0039] The housing 3 and the liquid separator 1 are connected by threads, which allows the housing 3 and the liquid separator 1 to be disassembled by threads. This facilitates cleaning, inspection and replacement of parts inside the liquid separator. At the same time, an annular groove 11 is provided on the inner wall of the housing 3, and an O-ring 12 is installed in the annular groove 11. When the housing 3 and the liquid separator 1 are tightened by threads, the O-ring 12 will be compressed and deform elastically, thereby filling the tiny gap between the housing 3 and the liquid separator 1 and forming a reliable sealing barrier. This effectively prevents refrigerant from leaking from the threaded connection and ensures stable pressure inside the liquid separator and directional flow of refrigerant.

[0040] The flow distribution structure 6 is detachably fixed in the mounting groove 7 of the liquid distribution body 1 via the mounting base 8, which allows the flow distribution structure 6 with different spiral parameters to be replaced according to different flow requirements, so as to optimize the liquid distribution effect and improve the versatility of the liquid distributor, enabling it to be widely used in various refrigeration systems.

[0041] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
