[0047] like Figures 1 to 12As shown, according to an embodiment of the present utility model, a distributor 100 is proposed, comprising a shell 10, a plate body 20, and a diverter cone 30, wherein the shell 10 is provided with an inflow hole 111, the plate body 20 is arranged on the shell 10, and the plate body 20 comprises a first plate body 21 and a second plate body 22 respectively connected perpendicularly to the axial direction of the inflow hole 111, the first plate body 21 is provided with a diverter hole 201, the second plate body 22 is located on the side of the first plate body 21 away from the inflow hole 111 and is fitly connected, the first plate body 21 is provided with a mounting hole 205, and the second plate body 22 is provided with an avoidance hole 203, the avoidance hole 203 and the mounting hole 205 are coaxially arranged and connected, the diverter cone 30 is respectively fixed to the mounting hole 205 and the avoidance hole 203, and the diverter cone 30 is used to guide the fluid from the inflow hole 111 to the diverter hole 201.

[0048] According to the distributor of the present invention, the diverter cone 30 is tightly fixed to the first plate 21 and the second plate 22, respectively, effectively solving the problem of loose fixation between the first plate 21 and the second plate 22, enhancing the connection strength between the two, and preventing loosening or displacement. At the same time, by providing an avoidance hole 203 on the first plate 21 and a mounting hole 205 on the second plate 22, and by providing the avoidance hole 203 and the mounting hole 205 coaxially and in communication, the diverter cone 30 can be firmly fixed between the first plate 21 and the second plate 22. Since the diverter cone 30 is respectively fixed to the mounting hole 205 and the avoidance hole 203, this dual fixing structure effectively improves the installation stability of the diverter cone 30 and avoids the loosening or displacement caused by the support of a single plate.

[0049] Specifically, the housing 10 is provided with an inflow hole 111 and an expansion cavity 103. The plate 20 encloses the housing 10 to form the expansion cavity 103. The plate 20 includes a first plate 21 and a second plate 22. The first plate 21 is adjacent to the inflow hole 111 and is provided with a plurality of diverter holes 201. The second plate 22 is connected to the side of the first plate 21 facing away from the inflow hole 111 and is provided with a plurality of insertion holes 202. The plurality of diverter holes 201 and the plurality of insertion holes 202 are connected in a one-to-one correspondence. The avoidance hole 203 sequentially passes through the first plate 21 and the second plate 22 along the axis of the inflow hole 111.

[0050] Specifically, the diverter cone 30 is a conical structure. From the top to the bottom of the diverter cone 30, there are a cone 31, an extension section 32 and a second flange 33 in sequence. The extension section 32 is cylindrical. One end of the extension section 32 is connected to the cone 31, and the other end is connected to the second flange 33. The bottom surface of the cone 31 is connected to the extension section 32.

[0051] Specifically, multiple diverter holes 201 are spaced at equal intervals along the circumference of the diverter cone 30. By arranging the diverter holes 201 at equal intervals, the fluid is evenly distributed along the circumference of the diverter cone 30. Because the spacing between each diverter hole 201 is equal, there is no deviation or imbalance when the fluid enters the diverter holes 201 from the inlet hole 111, ensuring uniform fluid distribution. This helps avoid localized flow rates that are too high or too low. At the same time, the equally spaced diverter holes 201 contribute to balanced distribution of the fluid within the expansion chamber 103. When the fluid passes through the diverter cone 30, each diverter hole 201 receives the same amount of fluid, further improving the balance of the distributor 100. This design not only improves fluid distribution accuracy but also reduces the occurrence of uneven flow within the expansion chamber 103. If the spacing between the diverter holes 201 is uneven, excessive flow in some diverter holes 201 may occur, thereby increasing local pressure and affecting the stability of the distributor 100. The equal spacing setting can effectively avoid this problem and ensure that the fluid flow rate and pressure received by each diversion hole 201 are similar, thereby reducing local pressure fluctuations and improving the overall stability of the system.

[0052] Specifically, the diverter cone 30 is coaxially arranged with the inlet hole 111. This coaxial arrangement ensures that after the fluid enters the expansion chamber 103 from the inlet hole 111, it flows directly along the central axis of the diverter cone 30, thereby improving the accuracy and stability of fluid guidance. After entering the diverter cone 30, the fluid is gradually dispersed along the diverter cone 30 to each diverter hole 201, avoiding deviation and turbulence during fluid entry, thereby improving the stability and uniformity of fluid distribution.

[0053] like Figures 1 to 6 As shown, in some embodiments, a positioning structure 2031 is provided on the plate body 20, and the positioning structure 2031 is an annular groove arranged along the circumference of the avoidance hole 203, and the annular groove is arranged between the first plate body 21 and the second plate body 22. The diverter cone 30 includes a second annular flange 33, and the second flange 33 is fixed in the annular groove. In this embodiment, the design of the annular groove provides more fixing area, increases the number and strength of the fixing points. The second flange 33 of the diverter cone 30 fits tightly in the annular groove, further improving the fixing stability and preventing the structure from loosening or shifting under high pressure or long-term use. At the same time, the first plate body 21 and the second plate body 22 are clamped and positioned by the annular groove, ensuring the precise positioning of the diverter cone 30, so that the fixing operation can be completed more accurately during the installation process, reducing the deviation that may occur during the fixing process. In addition, since the annular groove can effectively disperse stress, the load borne by the diverter cone 30 during operation is more uniform, which reduces the stress concentration at the fixed connection, and makes the diverter assembly 1000 have better fatigue resistance when facing repeated fluid impact or long-term operation, thereby extending the service life of the equipment.

[0054] Specifically, the annular groove includes a first step countersunk hole 211 and a second step countersunk hole 221. The first step countersunk hole 211 is provided on the end surface of the first plate 21 facing away from the inflow hole 111 and is coaxially arranged with the avoidance hole 203. The second step countersunk hole 221 is provided on the end surface of the second plate 22 facing the inflow hole 111 and is surrounded by the mounting hole 205. The first step countersunk hole 211 and the second step countersunk hole 221 together form an annular groove. The annular groove formed by the combination of the first step countersunk hole 211 and the second step countersunk hole 221 provides a clear positioning and fixing position for the second flange 33 of the diverter cone 30, ensuring that the diverter cone 30 can be accurately fixed between the first plate 21 and the second plate 22, reducing possible displacement or misalignment during the fixing process, and improving the accuracy and stability of the fixing. At the same time, the first step countersunk hole 211 and the second step countersunk hole 221 cooperate to form an annular groove, providing a closed positioning structure, ensuring a tight connection between the diverter cone 30 and the plate body 20, avoiding the problem of fluid leakage, and thus improving the sealing of the distributor 100.

[0055] like Figure 6 As shown, it can be understood that along the axial direction of the avoidance hole 203, the first step countersunk hole 211 has a first depth (such as Figure 6 h1 in the figure), the second step counterbore 221 has a second depth (as shown in FIG. Figure 6 The sum of the first depth and the second depth is equal to the thickness of the second flange 33 (as shown in h2). Figure 3 (As shown in Figure H). The depths of the first step countersunk hole 211 and the second step countersunk hole 221 precisely match the thickness of the second flange 33 of the diverter cone 30, ensuring that the second flange 33 is fully embedded in the annular groove. This precise fit not only enhances the stability of the fixation, but also effectively prevents the flange from being inaccurately positioned or deviating during the fixation process, thereby improving the accuracy and reliability of the fixation. In addition, by ensuring that the sum of the depths of the first step countersunk hole 211 and the second step countersunk hole 221 is equal to the thickness of the second flange 33, a tight fit is formed between the second flange 33 and the annular groove, which helps the diverter cone 30 remain stable when subjected to fluid impact and avoids performance degradation caused by structural looseness.

[0056] like Figure 2 and Figure 5 As shown, it can be understood that along the radial direction of the avoidance hole 203, the first step counterbore 211 has a first diameter (such as Figure 5 d1 in the figure), the second step counterbore 221 has a second diameter (as shown in FIG. Figure 5 d2 in the figure), the first diameter, the second diameter and the outer diameter of the second flange 33 (as shown in FIG. Figure 2(shown as d4 in the figure). By designing the first diameter of the first step counterbore 211 and the second diameter of the second step counterbore 221 to be consistent with the outer diameter of the second flange 33, the second flange 33 of the diverter cone 30 can be precisely engaged with the annular groove in the radial direction, avoiding loosening or radial displacement of the flange in the annular groove, thereby ensuring the stability of the diverter cone 30 during operation. At the same time, due to the equal diameters, the second flange 33 can be in close contact with the inner wall of the annular groove, ensuring a uniform contact surface during affixation. This uniform contact and affixation can disperse the stress at the affixed joint, enhancing the firmness and durability of the affixed joint. In particular, the stability of the positioning structure is further guaranteed when subjected to high-pressure fluids.

[0057] It is understandable that the diverter cone 30 includes an extension section 32, and the circumferential side wall of the extension section 32 is fixedly connected to the avoidance hole 203. By providing the extension section 32 and fixing its circumferential side wall to the inner wall of the avoidance hole 203, the fixing firmness between the diverter cone 30 and the plate body 20 is further enhanced. The solution of the extension section 32 extending deep into the avoidance hole 203 provides a larger linear contact area, thereby increasing the number and strength of the fixing points, preventing the diverter cone 30 from loosening or shifting during long-term use. In addition, the fixing of the circumferential side wall of the extension section 32 to the inner wall of the avoidance hole 203 provides a larger fixing surface area, which not only improves the firmness of the fixing, but also significantly enhances the impact resistance of the diverter cone 30 when facing high-pressure or high-speed fluids, reduces the stress concentration at the fixing points, and thus improves the reliability of the fixing.

[0058] like Figures 7 to 12 As shown, in some embodiments, a positioning structure 2031 is provided on the second plate body 22, and the positioning structure 2031 includes a third step countersunk hole 222 arranged along the circumference of the mounting hole 205. The third step countersunk hole 222 is provided on the end surface of the second plate body 22 away from the inflow hole 111. The diverter cone 30 includes an annular second flange 33, and the second flange 33 is fixedly connected to the third step countersunk hole 222. In this embodiment, the third step countersunk hole 222 provides a precise fixed positioning area for the second flange 33 of the diverter cone 30, increases the contact area of ​​the fixed connection, and makes the fixed point more stable. At the same time, by providing the third step countersunk hole 222 on the second plate body 22, the second flange 33 of the diverter cone 30 can be accurately embedded, thereby providing precise radial positioning and a stable fixed connection. This design not only enhances the fixing firmness of the diverter cone 30, but also reduces the offset and error during the fixing.

[0059] It is understandable that the diverter cone 30 includes an extension section 32, and the circumferential side walls of the extension section 32 are fixedly connected to the inner wall of the avoidance hole 203 and part of the mounting hole 205. The extension section 32 extends deep into the first plate body 21 and the second plate body 22, and is fixedly connected to the inner wall of the avoidance hole 203 and the inner wall of the mounting hole 205. Through this design, the fixing surface is extended from the simple fixing of the plate body 20 to the side wall of the extension section 32, which significantly increases the fixing area. The larger fixing area enhances the connection stability of the first plate body 21 and the second plate body 22, and reduces the possibility of loosening and displacement. At the same time, the design of the extension section 32 distributes the stress at the connection more evenly between the first plate body 21 and the second plate body 22, reducing the risk of deformation caused by local stress concentration at the fixing point. Stress dispersion effectively improves the fatigue resistance of the plate body 20 under high pressure or high temperature conditions, ensuring its stability during long-term operation. Furthermore, the fixed connection between the extension section 32 and the inner wall of the plate body 20 provides a more stable structure, effectively reducing the stress on the fixed connection points when the diverter assembly 1000 is subjected to vibration or impact. This makes the diverter assembly 1000 more durable in vibration environments or rapidly changing fluid pressures, and the connection is less likely to suffer from fatigue fracture.

[0060] like Figure 11 As shown, it can be understood that the third step counterbore 222 has a third diameter (such as Figure 11 (as shown in d3 in the figure), the third diameter is equal to the outer diameter of the second flange 33. The third diameter of the third step countersunk hole 222 is equal to the outer diameter of the second flange 33, so that the second flange 33 can be accurately embedded in the countersunk hole, ensuring that no radial offset occurs during fixation. This precise fit improves the accuracy of fixation, ensures a stable connection between the diverter cone 30 and the plate body 20, and avoids insufficient fixation strength due to deviation. By tightly embedding the second flange 33 into the third step countersunk hole 222, which is equal to its outer diameter, the structure after fixation is more stable. When the distributor 100 is in operation, especially when facing vibration or high-pressure shock, this precise fit can effectively resist loosening caused by vibration or shock, and enhance the fatigue resistance of the fixing point and the durability of the overall structure.

[0061] In some embodiments, the fixing method is to provide a welding material layer or an adhesive material layer between the diverter cone and the plate body, wherein the welding material layer can connect the diverter cone 30 with the first plate body 21 and the second plate body 22 by high-temperature melting, and the adhesive material layer firmly fixes the diverter cone 30 between the first plate body 21 and the second plate body 22 by using a high-strength adhesive.

[0062] Specifically, the fixing method is integral welding, in which a layer of welding paste is evenly coated along the circumferential sidewalls of the second flange 33 and the extension section 32 in the contact area between the second flange 33 of the diverter cone 30 and the plate body 20 (including the first plate body 21 and the second plate body 22). The welding paste should be made of a material suitable for high-temperature welding to ensure that it can effectively fill small gaps during welding and enhance the sealing and strength after welding. The diverter cone 30 is accurately embedded in the preset welding position between the first plate body 21 and the second plate body 22 through the second flange 33. The extension section 32 of the diverter cone 30 is also inserted at the same time and contacts the inner wall of the avoidance hole 203 to ensure complete coverage of the welding area. Then, after the diverter cone 30 is positioned, the welding area is heated using suitable welding equipment. The welding paste gradually melts at high temperature and fills the contact gap between the diverter cone 30 and the plate body 20. Under the action of high temperature, the welding paste, the second flange 33 and the extension section 32 of the diverter cone 30 and the plate body 20 form an integrated weld. The entire welding process ensures uniform distribution of the solder paste, avoiding gaps or incomplete welds. After welding is complete, the temperature is gradually lowered, allowing the solder paste to cool and solidify, forming a stable bond. The diverter cone 30 and the plate body 20 are integrally welded using solder paste, forming a tight and durable connection that ensures structural stability. The use of solder paste fills small gaps during the welding process, ensuring full coverage and sufficient fusion of the weld area. Through integrated welding, the connection between the diverter cone 30 and the plate body 20 is more stable, effectively preventing loosening and detachment.

[0063] In some embodiments, the distributor 100 further includes a second filter screen. A diverter cone 30 is disposed within the expansion chamber 103 and connected to the plate body 20. A second filter chamber is formed between the second filter screen and the plate body 20, and multiple diverter holes 201 are all connected to the second filter chamber. The diverter cone 30 allows the fluid to be initially diverted after entering the expansion chamber 103. The conical structure of the diverter cone 30 can evenly guide the fluid in all directions of the expansion chamber 103, ensuring that the fluid is evenly distributed on the surface of the second filter screen, reducing fluid turbulence within the expansion chamber 103, optimizing the fluid distribution path, and thereby improving distribution efficiency. The second filter screen is located behind the diverter cone 30 and forms a second filter chamber with the plate body 20, capable of filtering the fluid passing through the diverter cone 30. Since the fluid in the second filter chamber can maintain a uniform flow rate and flow rate under the dual effects of the diverter cone 30 and the second filter screen, the fluid flow received by each diverter hole 201 is relatively balanced. This uniform distribution design can improve the diversion accuracy of the entire system, especially in fluid delivery systems with high precision requirements. It has significant advantages.

[0064] 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 second filter screen is an annular groove-shaped filter screen. The outer ring of the second filter screen is connected to the circumferential edge of the plate body 20, and the inner ring of the second filter screen 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 can ensure 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 along the circumferential surface of the diverter cone 30 into the second filter cavity 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 groove-shaped design of the second filter screen not only provides a larger filtering surface area, but also can better capture particulate matter in the fluid. The annular structure allows the filter to evenly surround the diverter cone 30, ensuring that the fluid is fully filtered before entering the diverter hole 201, thereby enhancing filtration efficiency. Simultaneously, the outer ring of the second filter is connected to the circumferential edge of the plate body 20, while the inner ring is connected to the junction of the diverter cone 30 and the plate body 20, forming a sealed filter chamber structure. This effectively prevents fluid from bypassing the second filter and directly entering the diverter hole 201, ensuring that all fluid is fully filtered before entering the diverter hole 201, thereby improving filtration accuracy and system reliability.

[0065] Figure 13 As shown, this embodiment further 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 inflow hole 111 through the inlet pipe 301. Specifically, the housing 10 is provided with a first inserting portion, 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 is based on 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.

[0066] In some embodiments, the flow diversion assembly 1000 further includes a retaining member, which includes a first retaining plate and a second retaining plate. The first retaining plate is provided with a plurality of first retaining holes, and the second retaining plate is provided with a plurality of second retaining holes. The plurality of first retaining holes and the plurality of second retaining holes are coaxially arranged in a one-to-one correspondence. Compared to the first embodiment, the dual retaining design between the first and second retaining plates supports the first connecting tube 200 via two coaxial first and second retaining holes, significantly enhancing the stability of the first connecting tube 200. Compared to a single retaining plate, the dual retaining plates can effectively prevent any tilting or shaking of the first connecting tube 200 during installation and affixation, ensuring that it is in the correct position before affixation.

[0067] It is understood that the first and second limiting plates are connected by a support structure. The support structure connects the first and second limiting plates, forming a stable limiting member. The support structure effectively prevents relative displacement between the two limiting plates during attachment or installation, ensuring that the first connecting tube 200 remains in the correct limiting position.

[0068] like Figure 14 As 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.
