Description

Technical Field

[0001] This invention relates to the field of heating, ventilation and air conditioning (HVAC) equipment technology, specifically to distributors, distribution components, and HVAC equipment. Background Technology

[0002] In existing distributor structures, the fixing method between the cover plate and the orifice plate is often not secure, resulting in poor reliability during use. This not only affects the distributor's performance but also causes insufficient bonding quality, increasing the difficulty and cost of maintenance. Summary of the Invention

[0003] The purpose of this invention is to at least solve the problem of insecure fixing between the cover plate and the diversion orifice plate. This purpose is achieved through the following technical solution:

[0047] like Figures 1 to 12 As shown, according to an embodiment of the present invention, a distributor 100 is provided, including a housing 10, a plate 20, and a flow divider cone 30. The housing 10 is provided with an inlet hole 111. The plate 20 is disposed on the housing 10 and includes a first plate 21 and a second plate 22 that are perpendicularly connected to the axial direction of the inlet hole 111. The first plate 21 is provided with a flow divider hole 201. The second plate 22 is located on the side of the first plate 21 away from the inlet hole 111 and is fitted together. The first plate 21 is provided with a mounting hole 205, and the second plate 22 is provided with a clearance hole 203. The clearance hole 203 and the mounting hole 205 are coaxially arranged and connected. The flow divider cone 30 is fixedly connected to the mounting hole 205 and the clearance hole 203 respectively. The flow divider cone 30 is used to guide fluid from the inlet hole 111 to the flow divider hole 201.

[0048] According to the distributor of the present invention, the diverting cone 30 is tightly fixed to the first plate 21 and the second plate 22 respectively, which effectively solves the problem of loose fixation between the first plate 21 and the second plate 22, enhances the connection strength between the two, and prevents loosening or displacement. At the same time, by providing a clearance hole 203 on the first plate 21 and a mounting hole 205 on the second plate 22, and by providing a clearance hole 203 and a mounting hole 205 coaxially and connected, the diverting cone 30 can be stably fixed between the first plate 21 and the second plate 22. Since the diverting cone 30 is fixed to both the mounting hole 205 and the clearance hole 203 respectively, this double fixing structure effectively improves the installation stability of the diverting cone 30 and avoids the problem of loosening or displacement caused by a single plate support.

[0049] Specifically, the housing 10 is provided with an inflow hole 111 and an expansion cavity 103. The plate 20 closes 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 close to the inflow hole 111 and is provided with multiple diversion holes 201. The second plate 22 is connected to the side of the first plate 21 away from the inflow hole 111 and is provided with multiple insertion holes 202. The multiple diversion holes 201 and the multiple insertion holes 202 are connected in a one-to-one correspondence. The clearance hole 203 passes through the first plate 21 and the second plate 22 sequentially along the axial direction of the inflow hole 111.

[0050] Specifically, the diverting cone 30 has a conical structure. From the top to the bottom of the diverting 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 diversion holes 201 are spaced at equal intervals along the circumferential direction of the diversion cone 30. By arranging the diversion holes 201 at equal intervals, the fluid is ensured to be uniformly distributed in the circumferential direction of the diversion cone 30. Since the intervals between each diversion hole 201 are equal, no deviation or imbalance occurs when the fluid enters the diversion hole 201 from the inlet hole 111, ensuring uniform fluid distribution. This helps avoid situations where the local flow rate is too high or too low. Simultaneously, the equally spaced diversion holes 201 contribute to the balanced distribution of fluid within the expansion chamber 103. When the fluid passes through the diversion cone 30, each diversion hole 201 receives the same amount of fluid, further improving the balance of the distributor 100. This design not only improves the accuracy of fluid distribution but also reduces the occurrence of uneven flow within the expansion chamber 103. If the spacing of the diversion holes 201 is uneven, some diversion holes 201 may experience excessive flow, thereby increasing local pressure and affecting the stability of the distributor 100. Equal spacing can effectively avoid this problem, ensuring that the fluid flow rate and pressure received by each diversion orifice 201 are similar, thereby reducing local pressure fluctuations and improving the overall stability of the system.

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

[0053] like Figures 1 to 6 As shown, in some embodiments, the plate 20 is provided with a positioning structure 2031, which is an annular groove arranged circumferentially along the clearance hole 203. The annular groove is located between the first plate 21 and the second plate 22. The diverting cone 30 includes a second flange 33 in an annular shape, which is fixedly connected to the annular groove. In this embodiment, the design of the annular groove provides more fixing area, increasing the number and strength of fixing points. The second flange 33 of the diverting 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 annular groove clamps and positions the first plate 21 and the second plate 22, ensuring the precise positioning of the diverting cone 30, enabling more accurate fixing operations during installation and reducing possible deviations during fixing. In addition, since the annular groove can effectively disperse stress, the load on the flow divider cone 30 is more uniform during operation, reducing stress concentration at the fixed joint. This makes the flow divider assembly 1000 more resistant to fatigue when facing repeated fluid impacts or long-term operation, thereby extending the service life of the equipment.

[0054] Specifically, the annular groove includes a first stepped countersunk hole 211 and a second stepped countersunk hole 221. The first stepped countersunk hole 211 is located on the end face of the first plate 21 facing away from the inflow hole 111 and is coaxially arranged with the clearance hole 203. The second stepped countersunk hole 221 is located on the end face of the second plate 22 facing the inflow hole 111 and is coaxial with the mounting hole 205. The first stepped countersunk hole 211 and the second stepped countersunk hole 221 enclose each other to form an annular groove. The annular groove formed by the combination of the first stepped countersunk hole 211 and the second stepped countersunk hole 221 provides a clear positioning and fixed position for the second flange 33 of the flow divider cone 30, ensuring that the flow divider 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. Meanwhile, the cooperation of the first step countersunk hole 211 and the second step countersunk hole 221 forms an annular groove, which provides a closed positioning structure, ensuring a tight connection between the flow divider cone 30 and the plate 20, avoiding the problem of fluid leakage, thereby improving the sealing performance of the distributor 100.

[0055] like Figure 6 As shown, it can be understood that, along the axial direction of the clearance hole 203, the first stepped countersunk hole 211 has a first depth (e.g., Figure 6 As shown in h1), the second-step countersunk hole 221 has a second depth (as shown in h1). Figure 6 As shown in h2), 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 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 flow divider 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 connection but also effectively prevents inaccurate or misaligned flange positions during the connection process, thereby improving the accuracy and reliability of the connection. Furthermore, by ensuring that the sum of the depths of the first-step countersunk hole 211 and the second-step countersunk hole 221 equals the thickness of the second flange 33, a tight fit is formed between the second flange 33 and the annular groove. This helps the flow divider cone 30 remain stable under fluid impact, avoiding performance degradation caused by structural loosening.

[0056] like Figure 2 and Figure 5 As shown, it can be understood that, along the radial direction of the clearance hole 203, the first stepped countersunk hole 211 has a first diameter (e.g., Figure 5 As shown in d1), the second-step countersunk hole 221 has a second diameter (as shown in d1). Figure 5 As shown in d2), the first diameter, the second diameter, and the outer diameter of the second flange 33 (as shown in d2). Figure 2(As shown in d4) The three diameters are equal. By designing the first diameter of the first countersunk hole 211, the second diameter of the second countersunk hole 221, and the outer diameter of the second flange 33 to be consistent, the second flange 33 of the flow divider cone 30 can achieve precise engagement 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 flow divider cone 30 during operation. At the same time, since the diameters are equal, the second flange 33 can make close contact with the inner wall of the annular groove, ensuring uniform contact surface during fixing. This uniform contact and fixing can disperse the stress at the fixing point, enhance the firmness and durability of the fixing, and especially when subjected to high-pressure fluid, the stability of the positioning structure is further guaranteed.

[0057] Understandably, the flow divider cone 30 includes an extension section 32, the circumferential sidewall of which is fixedly connected to the clearance hole 203. By providing the extension section 32 and fixing its circumferential sidewall to the inner wall of the clearance hole 203, the fixing strength between the flow divider cone 30 and the plate 20 is further enhanced. The extension section 32 extending into the clearance hole 203 provides a larger linear contact area, thereby increasing the number and strength of the fixing points and preventing the flow divider cone 30 from loosening or shifting during long-term use. In addition, the fixing of the circumferential sidewall of the extension section 32 to the inner wall of the clearance hole 203 provides a larger fixing surface area, which not only improves the fixing strength but also significantly enhances the impact resistance of the flow divider cone 30 when facing high-pressure or high-speed fluids, reduces 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, the second plate 22 is provided with a positioning structure 2031. The positioning structure 2031 includes a third stepped countersunk hole 222 arranged circumferentially along the mounting hole 205. The third stepped countersunk hole 222 is located on the end face of the second plate 22 opposite to the inflow hole 111. The diverting cone 30 includes a second flange 33 in an annular shape, and the second flange 33 is fixedly connected to the third stepped countersunk hole 222. In this embodiment, the third stepped countersunk hole 222 provides a precise fixing and positioning area for the second flange 33 of the diverting cone 30, increasing the contact area for fixing and making the fixing point more stable. At the same time, by providing the third stepped countersunk hole 222 on the second plate 22, the second flange 33 of the diverting cone 30 can be accurately embedded, thereby providing precise radial positioning and a stable fixing connection. This design not only enhances the fixing firmness of the diverting cone 30, but also reduces the offset and error during fixing.

[0059] Understandably, the flow divider cone 30 includes an extension section 32, the circumferential sidewall of which is fixedly connected to the inner wall of the clearance hole 203 and part of the mounting hole 205. The extension section 32 extends into the first plate 21 and the second plate 22, and is fixedly connected to the inner wall of the clearance hole 203 and the inner wall of the mounting hole 205. Through this design, the fixing surface extends from a simple fixing to the plate 20 to the sidewall of the extension section 32, significantly increasing the fixing area. The larger fixing area enhances the connection stability of the first plate 21 and the second plate 22, reducing the possibility of loosening and displacement. Simultaneously, the design of the extension section 32 distributes the stress at the connection point more evenly between the first plate 21 and the second plate 22, reducing the risk of deformation caused by localized stress concentration at the fixing point. This stress dispersion effectively improves the fatigue resistance of the plate 20 under high pressure or high temperature conditions, ensuring its stability during long-term operation. Furthermore, due to the fixed connection between the extension section 32 and the inner wall of the plate 20, the structure is more stable, especially when the diversion assembly 1000 is subjected to vibration or impact, it can effectively reduce the stress on the fixed connection point. This makes the diversion assembly 1000 more durable in vibration environments or rapidly changing fluid pressures, and fatigue fracture is less likely to occur at the connection point.

[0060] like Figure 11 As shown, it can be understood that the third-step countersunk hole 222 has a third diameter (as shown in the figure). Figure 11 As shown in d3, 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, allowing the second flange 33 to be precisely embedded in the countersunk hole, ensuring no radial displacement occurs during the fixing process. This precise fit improves the fixing accuracy, ensuring a stable connection between the diverter cone 30 and the plate 20, and avoiding insufficient fixing strength due to deviation. By tightly embedding the second flange 33 into the third-step countersunk hole 222, which has the same outer diameter, the fixed structure is more stable. During the operation of the distributor 100, especially when facing vibration or high-pressure impact, this precise fit can effectively resist loosening caused by vibration or impact, enhancing the fatigue resistance of the fixing point and the durability of the overall structure.

[0061] In some embodiments, the connection is achieved by providing a welding material layer or an adhesive material layer between the diverter cone and the plate. The welding material layer can be used to connect the diverter cone 30 to the first plate 21 and the second plate 22 by high-temperature melting, while the adhesive material layer can be used to firmly fix the diverter cone 30 between the first plate 21 and the second plate 22 using a high-strength adhesive.

[0062] Specifically, the connection method is integral welding. This integral welding involves uniformly coating a layer of welding paste along the circumferential sidewalls of the second flange 33 and extension 32 in the contact area between the flow divider cone 30 and the plate 20 (including the first plate 21 and the second plate 22). The welding paste should be made of a material suitable for high-temperature welding to ensure effective filling of minute gaps during welding, enhancing the sealing and strength after welding. The flow divider cone 30 is accurately embedded into the pre-set welding position between the first plate 21 and the second plate 22 via the second flange 33. The extension 32 of the flow divider cone 30 is also simultaneously inserted and contacts the inner wall of the clearance hole 203, ensuring complete coverage of the welding area. Next, after positioning the flow divider cone 30, the welding area is heated using suitable welding equipment. The welding paste gradually melts at high temperature, filling the contact gap between the flow divider cone 30 and the plate 20. Under high temperature, the welding paste, the second flange 33 and extension 32 of the flow divider cone 30, and the plate 20 form an integral fusion. The entire welding process ensures uniform distribution of the welding paste, avoiding gaps or incomplete welding. After welding, the temperature is gradually reduced, allowing the welding paste to cool and solidify, forming a stable bond layer. The flow divider cone 30 and the plate 20 are integrally welded using welding paste, forming a tight and durable connection, ensuring structural stability. The welding paste fills tiny gaps during the welding process, ensuring complete coverage and full fusion of the welding area. Through integral welding, the connection between the flow divider cone 30 and the plate 20 is more stable, effectively preventing loosening and detachment.

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

[0064] It is understood that the flow divider cone 30 is coaxially arranged with the inlet hole 111, and multiple flow dividers 201 are spaced apart circumferentially along the flow divider cone 30. The second filter screen is an annular grooved filter screen, with the outer ring of the second filter screen connected to the circumferential edge of the plate 20, and the inner ring of the second filter screen connected to the connection between the plate 20 and the flow divider cone 30. The flow divider 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 flow divider cone 30, thereby improving the accuracy and stability of fluid guidance. After the fluid enters the flow divider cone 30, it will pass through the second filter screen along the circumferential surface of the flow divider cone 30 and enter the second filter chamber, and gradually disperse into each flow divider hole 201, avoiding the deviation and turbulence phenomenon when the fluid enters, thereby improving the stability and uniformity of fluid distribution. The grooved design of the second filter screen not only provides a larger filtration surface area, but also better captures particulate matter in the fluid. The annular structure ensures that the filter screen evenly surrounds the flow divider cone 30, guaranteeing that the fluid undergoes sufficient filtration before entering the flow divider orifice 201, thus enhancing filtration efficiency. Simultaneously, the outer ring of the second filter screen connects to the circumferential edge of the plate 20, and the inner ring connects to the junction of the flow divider cone 30 and the plate 20, forming a sealed filter chamber structure. This effectively prevents fluid from bypassing the second filter screen and directly entering the flow divider orifice 201, ensuring that all fluid undergoes sufficient filtration before entering the flow divider orifice 201, thereby improving filtration accuracy and system reliability.

[0065] Figure 13 As shown, this embodiment also provides a flow-diverting assembly 1000, which includes the aforementioned distributor 100, second connecting pipe 300, and first connecting pipe 200. The second connecting pipe 300 includes an inlet pipe 301 and an outlet 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 insertion part for receiving the inlet pipe 301. The first connecting pipe 200 is connected to the flow-diverting hole 201 and inserted into the insertion hole 202 of the second plate 22. The flow-diverting assembly 1000 takes the distributor 100 as its core part and achieves uniform distribution of fluid through its flow-diverting cone 30, first plate 21, and flow-diverting hole 201. The second connecting pipe 300 is connected to the inlet port 111 of the distributor 100 and is responsible for introducing fluid from the main system into the expansion chamber 103, while the first connecting pipe 200 is connected to the diversion port 201 and is used to further transport fluid from the diversion port 201 to various downstream pipelines or terminal equipment.

[0066] In some embodiments, the diversion assembly 1000 further includes a limiting member, which includes a first limiting plate and a second limiting plate. The first limiting plate has a plurality of first limiting holes, and the second limiting plate has a plurality of second limiting holes. The plurality of first limiting holes and the plurality of second limiting holes are coaxially arranged in a one-to-one correspondence. Compared with the first embodiment, the dual limiting design between the first limiting plate and the second limiting plate, by supporting the first connecting pipe 200 through two coaxial first limiting holes and second limiting holes, significantly enhances the stability of the first connecting pipe 200. Compared with a single limiting plate, the dual limiting plates can effectively prevent any tilting or shaking of the first connecting pipe 200 during installation and fixing, ensuring that it is in the correct position before fixing.

[0067] Understandably, the first and second limiting plates are connected by a support structure. This support structure forms a stable limiting component. It effectively prevents relative displacement between the two limiting plates during fixing or installation, ensuring that the first connecting pipe 200 remains in the accurate limiting position.

[0068] like Figure 14 As shown, this embodiment also provides a heating, ventilation, and air conditioning (HVAC) device 1, which includes the aforementioned distribution assembly 1000, first heat exchanger 2000, second heat exchanger 3000, compressor 4000, refrigeration throttling valve 5000, and four-way valve 6000. After receiving refrigerant from the distribution assembly 1000, the first heat exchanger 2000 undergoes a heat absorption process, causing the refrigerant to evaporate and absorb heat from the environment. The low-pressure gaseous refrigerant received from the first heat exchanger 2000 by the compressor 4000 is pressurized and transformed into 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 regulate the flow direction of the refrigerant and switch between cooling and heating modes. In cooling mode, the refrigerant returns to the compressor 4000 via the second heat exchanger 3000, the cooling expansion valve 5000, the flow distribution assembly 1000, and the first heat exchanger 2000. In heating mode, the refrigerant returns to the compressor 4000 from the first heat exchanger 2000. The design of the entire HVAC system 1 achieves higher fluid control precision through the flow distribution assembly 1000, enhancing system stability. The precise coordination and flow control of each component ensure stable operation of the equipment under different operating conditions, reducing malfunctions and maintenance requirements.
