[0002] In HVAC equipment and similar fluid delivery systems, uniform distribution and filtration of liquids are crucial factors affecting equipment performance and lifespan. Prior art liquid distributors typically consist of a diverter and a filter, but these two components are separated. This separate design not only increases system complexity but also increases manufacturing and installation costs. Furthermore, the diverter's flow distribution is often suboptimal, leading to uneven flow as the liquid flows through different pipelines, thus impacting the overall efficiency of the system.

[0003] Especially under high-pressure and high-speed conditions, existing filters and diverters, when used separately, neither effectively refine droplets nor fully achieve uniform liquid diversion. This separate setup not only increases equipment size and installation complexity, but also increases maintenance costs, resulting in poor overall economic efficiency. Utility Model Content

[0044] like Figures 1 to 4 As shown, according to an embodiment of the present utility model, a distributor 100 is proposed, which includes a shell 10, a plate body 20 and a filter element 51. The shell 10 is provided with an inflow hole 111 and an expansion cavity 103. The plate body 20 is arranged on the shell 10 and closes the expansion cavity 103. A plurality of diversion holes 201 are provided on the plate body 20. The filter element 51 is arranged inside the expansion cavity 103 and connected to the plate body 20. The filter element 51 is arranged between the inflow hole 111 and the plurality of diversion holes 201. The filter element 51 is used to filter the fluid flowing from the inflow hole 111 to the diversion hole 201.

[0045] According to the distributor 100 of the present invention, by directly integrating the filter element 51 and the diverter hole 201 inside the expansion chamber 103, the fluid can flow from the inlet hole 111 through the filter element 51 to the diverter hole 201 when flowing through the distributor 100, avoiding the complexity of the equipment caused by the separate arrangement of the diverter and the filter in the traditional system. This integrated design reduces the number of parts, reduces the manufacturing difficulty and production cost, and reduces the volume of the equipment, making it easier to install and maintain. In addition, the present invention not only simplifies the equipment structure, but also can effectively filter impurities and ensure that the liquid is evenly distributed to each diverter hole 201, avoiding the problem of uneven flow. In addition, under high-pressure or high-speed fluid conditions, the presence of the filter element 51 can also effectively refine the droplets in the liquid and evenly distribute them to each diverter hole 201, which not only improves the pressure resistance of the distributor 100, but also can maintain stable flow distribution under high-speed fluid flow conditions.

[0046] In the first embodiment, the filter element 51 is a first filter screen 511. A first filter cavity 5111 is formed between the first filter screen 511 and the plate body 20. The multiple diverter holes 201 are all connected to the first filter cavity 5111. Specifically, after the fluid enters the expansion chamber 103 through the inlet hole 111, it is first filtered by the first filter screen 511. The filtered fluid then enters the first filter cavity 5111 and is evenly distributed into the downstream pipeline through the diverter holes 201. The first filter cavity 5111 formed between the first filter screen 511 and the plate body 20 not only filters out larger particles when the fluid passes through the first filter screen 511, but also further homogenizes the fluid through the buffering effect within the filter cavity. Because the multiple diverter holes 201 are directly connected to the first filter cavity 5111, the fluid is evenly distributed within the first filter cavity 5111, avoiding the uneven flow rate that may be caused by a single flow channel. This makes the fluid output from each diverter hole 201 more stable and controllable, thereby improving the overall distribution accuracy of the dispenser 100.

[0047] It can be understood that the first filter chamber 5111 is a semi-enclosed filter chamber formed between the first filter screen 511 and the plate body 20. After the fluid enters from the inlet hole 111, it must pass through the first filter screen 511 before entering the first filter chamber 5111. At the same time, the first filter chamber 5111 is also located in the expansion chamber 103.

[0048] Furthermore, the edge of the first filter screen 511 is connected to the edge of the plate body 20. By connecting the edge of the first filter screen 511 to the edge of the plate body 20, the first filter screen 511 is securely mounted, forming a complete first filter chamber 5111. This prevents fluid from bypassing the first filter screen 511 and directly entering the diverter hole 201, thereby ensuring that all fluid is filtered through the first filter screen 511. This significantly improves the reliability and efficiency of filtration. Due to the tight connection between the first filter screen 511 and the edge of the plate body 20, all fluid entering the expansion chamber 103 is forced to pass through the filter screen for filtration and even distribution, further optimizing the fluid flow path. This ensures a more uniform flow of fluid into each diverter hole 201, thereby improving the distribution accuracy of the entire system. Furthermore, by connecting the edge of the first filter screen to the plate body 20, a smooth fluid path is formed, preventing the formation of dead spots or stagnant areas in the filter. This reduces the fluid's residence time within the distributor 100, preventing the accumulation of dirt and particulate matter on the inner surface of the expansion chamber 103, thereby maintaining the cleanliness and effective filtration capabilities of the distributor 100. This is of great significance for extending the service life of the distributor 100. Furthermore, this edge connection design is particularly suitable for applications requiring high-precision filtration and diversion, such as fluid delivery systems like HVAC systems. In these applications, fluid purity and distribution uniformity have a crucial impact on system performance, and the edge connection ensures efficient and stable operation of the fluid delivery system.

[0049] Furthermore, the first filter screen 511 is a spherical cap-shaped filter screen and is arranged to protrude to one side of the inflow hole 111. The height of the first filter screen 511 coincides with the axis of the inflow hole 111. That is, the highest point of the first filter screen 511 is located on the central axis of the inflow hole 111. This design allows the fluid to first contact the central part of the spherical cap-shaped arc filter screen when entering from the inflow hole 111, and then be evenly distributed to the entire surface of the first filter screen 511. The spherical cap-shaped arc design allows the fluid to contact the surface of the first filter screen 511 in a more natural way, reducing the flow resistance caused by the plane structure of the filter screen. This fluid distribution method is more uniform, thereby improving the flow efficiency of the distributor 100 and reducing the energy loss when the fluid flows through the first filter screen 511. At the same time, the spherical cap-shaped arc filter screen has a larger filtering surface area than the flat filter screen. This means that the first filter 511 of the same volume can process more fluid and filter out more particulate matter, further enhancing the filtering effect of the dispenser 100. By increasing the filtering area, the pressure on the filter per unit area is effectively reduced, thereby extending the service life of the first filter 511.

[0050] In the second embodiment, the distributor 100 further includes a diverter cone 30, which is positioned within the expansion chamber 103 and connected to the plate body 20. The filter element 51 is a second filter screen 512, which is an annular, grooved filter screen. The second filter screen 512 surrounds the exterior of the diverter cone 30, forming a second filter cavity 5121 between the second filter screen 512 and the plate body 20. The plurality of diverter holes 201 are connected to the second filter cavity 5121. The diverter cone 30 allows for initial diversion of the fluid after entering the expansion chamber 103. The conical structure of the diverter cone 30 evenly directs the fluid in all directions within the expansion chamber 103, ensuring uniform distribution of the fluid across the surface of the second filter screen 512. This reduces fluid turbulence within the expansion chamber 103, optimizes the fluid distribution path, and thereby improves distribution efficiency. The annular structure allows the filter screen to evenly surround the diverter cone 30, ensuring that the fluid is fully filtered before entering the diverter holes 201, thereby enhancing filtration efficiency. Furthermore, the second filter 512 is located behind the top of the diverter cone 30 and forms a second filter chamber 5121 with the plate body 20, capable of filtering the fluid passing through the diverter cone 30. Because the fluid in the second filter chamber 5121 maintains a uniform flow rate and flow rate due to the dual effects of the diverter cone 30 and the second filter 512, the fluid flow received by each diverter hole 201 is relatively balanced. This uniform distribution design improves the diversion accuracy of the entire system, offering significant advantages, particularly in high-precision fluid delivery systems.

[0051] It is understandable that the diverter cone 30 is coaxially arranged with the inflow hole 111, and multiple diverter holes 201 are arranged at intervals along the circumference of the diverter cone 30. The outer ring of the second filter screen 512 is connected to the circumferential edge of the plate body 20, and the inner ring of the second filter screen 512 is connected to the connection between the plate body 20 and the diverter cone 30. The diverter cone 30 is coaxially arranged with the inflow hole 111. This coaxial arrangement ensures that after the fluid enters the expansion cavity 103 from the inflow hole 111, it flows directly along the central axis of the diverter cone 30, thereby improving the accuracy and stability of fluid guidance. After the fluid enters the diverter cone 30, it will pass through the second filter screen 512 along the circumferential surface of the diverter cone 30 and enter the second filter cavity 5121, and gradually disperse to each diverter hole 201, avoiding deviation and turbulence when the fluid enters, thereby improving the stability and uniformity of fluid distribution. The grooved design of the second filter screen 512 not only provides a larger filtering surface area, but also can better capture particulate matter in the fluid. At the same time, the outer ring of the second filter screen 512 is connected to the circumferential edge of the plate body 20, and the inner ring is connected to the connection between the diverter cone 30 and the plate body 20, forming a sealed filter chamber structure, which effectively prevents the fluid from bypassing the second filter screen 512 and directly entering the diverter hole 201, ensuring that all fluids are fully filtered before entering the diverter hole 201, thereby improving the filtration accuracy and system reliability.

[0052] It is understandable that the plate body 20 includes a first plate body 21 and a second plate body 22 connected to each other, a plurality of diverter holes 201 are provided on the first plate body 21, and a plurality of insertion holes 202 are provided on the second plate body 22, and the plurality of diverter holes 201 are connected to the plurality of insertion holes 202 in a one-to-one correspondence, and the diverter cone 30 and the first plate body 21 are an integral structure, and the diverter cone 30 is a conical structure. The diverter cone 30 and the first plate body 21 are both made of stainless steel, and the diverter cone 30 and the first plate body 21 are extruded through stainless steel, integrating the two parts in one production step, avoiding the complex process of separate processing and then assembly. This not only simplifies the production process and reduces possible errors in each link, but also significantly improves production efficiency. For the manufacturing process, one-piece extrusion molding helps to reduce manufacturing costs and shorten the production cycle. Through one-piece extrusion molding, the matching accuracy between the diverter cone 30 and the first plate body 21 is significantly improved, avoiding dimensional deviations caused by multi-step processing and assembly. The integrated manufacturing process ensures product consistency in geometry, size, and surface finish, thereby improving the processing quality of the entire system. This consistency ensures the precise matching of the diverter cone 30 and the diverter hole 201, so that the fluid flow received by each diverter hole 201 is balanced. At the same time, the integral molding of the diverter cone 30 and the diverter hole 201 plate eliminates the seams and irregular edges between the parts, thereby providing a smooth path for fluid flow. The smooth flow path reduces turbulence and turbulence, allowing the fluid to pass evenly through each diverter hole 201, improving the overall uniformity of the distributor 100. The fluid distribution is more uniform, which can effectively prevent local flow from being too large or too small.

[0053] Furthermore, the extended lines of the axes of the multiple diverter holes 201 pass through the bottom of the second filter cavity 5121. This means that the axis of each diverter hole 201, extending from the diverter hole 201 to the second filter screen 512, passes through the bottom of the second filter cavity 5121. This geometric design ensures that after filtration, the fluid enters the second filter cavity 5121 along the optimized path, making the fluid more uniform and orderly when entering the diverter hole 201, and reducing unnecessary turbulence and energy loss.

[0054] In some embodiments, both the first filter 511 and the second filter 512 are fixed to the plate 20 by welding. By welding, a firm connection is formed between the filter and the plate 20, which will not loosen or shift due to vibration, fluid impact or long-term use.

[0055] In other embodiments, the plate body 20 is provided with reinforcing ribs 23, and the filter element 51 is connected to the plate body 20 via the reinforcing ribs 23. The reinforcing ribs 23 are generally rib-like structures provided on the plate body 20 to enhance the support and fixation effect of the filter element 51. The reinforcing ribs 23 can be designed to be distributed along the circumference of the filter element 51 to ensure that the overall structure of the filter element 51 will not be deformed or fall off under the action of fluid pressure. Figure 2 As shown in the first embodiment, the reinforcing ribs 23 are distributed in a ring shape on the circumferential edge of the plate body 20, and the first filter screen 511 is connected to the circumferential edge of the plate body 20 through the reinforcing ribs 23. Figure 4 As shown, in the second embodiment, the number of reinforcing ribs 23 is two, one of which is distributed in a ring shape on the circumferential edge of the plate body 20, and the outer ring of the second filter screen 512 is connected to the reinforcing rib 23, and the other reinforcing rib 23 is also distributed in a ring shape at the connection between the plate body 20 and the diverter cone 30, and the inner ring of the second filter screen 512 is connected to the reinforcing rib 23.

[0056] It is understandable that the filter element 51 is connected to the reinforcement rib 23 by welding, and the reinforcement rib 23 is also welded to the plate body 20. This welding method provides a fixing effect with high strength and good stability, and is suitable for working conditions of high-pressure or high-flow fluid.

[0057] It is understandable that the reinforcement rib 23 is connected to the filter element 51 by riveting or screws, and then the reinforcement rib 23 is fixed to the plate body 20. This method can ensure a firm connection between the filter element 51 and the plate body 20 while making maintenance and replacement more convenient.

[0058] like Figure 5 As shown, this embodiment also provides a flow diversion assembly 1000, which includes the above-mentioned distributor 100, a second connecting pipe 300 and a first connecting pipe 200. The second connecting pipe 300 includes an inlet pipe 301 and an inlet pipe 302 connected to each other. The second connecting pipe 300 is connected to the inlet hole 111 through the inlet pipe 301. Specifically, the housing 10 is provided with a first inserting portion 11, which is used to accommodate the inlet pipe 301. The first connecting pipe 200 is connected to the diversion hole 201 and is inserted into the inserting hole 202 of the second plate body 22. The flow diversion assembly 1000 uses the distributor 100 as the core part and achieves uniform distribution of the fluid through its diversion cone 30, the first plate body 21 and the diversion hole 201. The second connecting pipe 300 is connected to the inflow hole 111 of the distributor 100 and is responsible for introducing the fluid from the main system into the expansion chamber 103, while the first connecting pipe 200 is connected to the diversion hole 201 and is used to further transport the fluid from the diversion hole 201 to various downstream pipelines or terminal devices.

[0059] like Figure 6As shown, this embodiment also provides a HVAC device 1, which includes the above-mentioned diversion component 1000, a first heat exchanger 2000, a second heat exchanger 3000, a compressor 4000, a refrigeration throttle valve 5000, and a four-way valve 6000. After the first heat exchanger 2000 receives the refrigerant from the diversion component 1000, the first heat exchanger 2000 performs a heat absorption process, causing the refrigerant to evaporate and absorb heat from the environment. The low-pressure gaseous refrigerant received by the compressor 4000 from the first heat exchanger 2000 is pressurized by the compressor 4000 and converted into a high-pressure gaseous refrigerant, which is then transported to the four-way valve 6000 through a pipeline. The four-way valve 6000 is used to adjust the flow direction of the refrigerant and switch between cooling and heating modes. In cooling mode, the refrigerant passes through the second heat exchanger 3000, the refrigeration throttle valve 5000, the flow diverter assembly 1000, and the first heat exchanger 2000 before returning to the compressor 4000. In heating mode, the refrigerant returns from the first heat exchanger 2000 to the compressor 4000. The design of the entire HVAC system 1 achieves higher fluid control precision through the flow diverter assembly 1000, enhancing system stability. The precise coordination and flow control of each component ensure stable operation under different operating conditions, reducing failures and maintenance requirements.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
