Description

Technical Field

[0001] The utility model relates to the technical field of HVAC equipment, in particular to a diversion component and HVAC equipment. Background Art

[0002] For HVAC equipment, there are generally two modes: cooling mode and heating mode. At this time, the cooling mode and heating mode are both for the indoor heat exchanger. When the indoor heat exchanger is in cooling mode or heating mode, the outdoor heat exchanger is in heating mode and cooling mode respectively.

[0003] In cooling mode, the compressor compresses the low-temperature, low-pressure refrigerant to a high-temperature, high-pressure state. The refrigerant then flows into the outdoor heat exchanger, where it condenses into a high-pressure, medium-temperature liquid refrigerant. This liquid refrigerant then passes through a throttling component, transforming it into a low-temperature, low-pressure, two-phase refrigerant. This two-phase refrigerant then flows through a distributor before entering the indoor heat exchanger. The distributor distributes the two-phase refrigerant according to the refrigerant demand for each flow path, and then enters the indoor heat exchanger for heat exchange, achieving the cooling effect. In this case, the outdoor heat exchanger acts as the condenser, and the indoor heat exchanger acts as the evaporator. After heat exchange, the low-temperature, low-pressure refrigerant ultimately enters the return air port of the compressor for subsequent circulation. In heating mode, the compressed refrigerant first enters the indoor heat exchanger for condensation. In this case, the indoor heat exchanger acts as the condenser, while the outdoor heat exchanger acts as the evaporator. The distributor distributes the liquid or gaseous refrigerant flowing from the condenser to the evaporator.

[0004] Currently, distributors often use stepped holes formed between the cover plate and the manifold plate to install connecting pipes, creating a welded lap joint. To ensure weld quality, a certain lap depth or area is typically required, which necessitates a thicker cover plate. Furthermore, the resulting lap joint is less reliable. Furthermore, the presence of the cover plate poses greater challenges to assembly and component alignment. Utility Model Content

[0060] like Figures 1-10 As shown, the present invention proposes a diverter assembly 1000, which is used for a HVAC device 1. Specifically, the HVAC device 1 may include a compressor 4000, a valve structure, a first heat exchanger 2000, and a second heat exchanger 3000 that are connected to each other. The compressor 4000 is used to compress the refrigerant. The refrigerant compressed by the compressor 4000 can flow through the second heat exchanger 3000 and the first heat exchanger 2000 in sequence, and finally flow back to the compressor 4000. The valve structure includes a four-way valve 6000. The four-way valve 6000 has four connecting ports, two of which are connected to the output end and the input end of the compressor 4000 respectively, and the other two connecting ports are connected to the input end of the second heat exchanger 3000 and the output end of the first heat exchanger 2000 respectively.

[0061] The first heat exchanger 2000 and the second heat exchanger 3000 enable the HVAC equipment 1 to switch between two functions: evaporator and condenser, i.e., heating mode and cooling mode. In this case, one of the first heat exchanger 2000 and the second heat exchanger 3000 is located outside the target space and functions as an outdoor unit, while the other is installed inside the target space and functions as an indoor unit. The outdoor and indoor units work together to form a circulation flow path, enabling the HVAC equipment 1 to cool, heat, dehumidify, and purify the air in the target space, thereby achieving a comfortable target space. The HVAC equipment 1 can have one outdoor unit and multiple indoor units, which are not specifically limited in this embodiment.

[0062] In this embodiment, HVAC equipment 1 is an air conditioner (in other embodiments of the present invention, HVAC equipment 1 includes but is not limited to a multi-split unit, a heat pump, a water heater, a swimming pool unit, etc.), first heat exchanger 2000 is an evaporator, and second heat exchanger 3000 is a refrigerator. First heat exchanger 2000 and second heat exchanger 3000 are connected by a flow diversion assembly 1000 to divert refrigerant from the gas / liquid collecting main pipe to multiple heat exchanger blocks. The valve structure also includes a refrigeration throttle valve 5000, which is arranged in communication between the flow diversion assembly 1000 and the second heat exchanger 3000.

[0063] In terms of overall design, Figures 1-10 As shown, the diverter assembly 1000 includes a distributor 100 and a first connecting tube 200. The distributor 100 includes a shell 10 and a plate 20. The shell 10 has an inflow hole 111 and an expansion cavity 103 connected to the inflow hole 111. At this time, the expansion cavity 103 has an opening, and the opening is located at the top of the expansion cavity 103. The plate 20 is arranged on the shell 10 and blocks the opening. A plurality of diverter holes 201 are provided on the plate 20, and each diverter hole 201 corresponds to a first connecting tube 200. A plug-in portion 204 is provided on the plate 20, and the plug-in portion 204 is adapted to be connected to the first connecting tube 200. The plug-in portion 204 has an extension structure 2041 that protrudes from the plate 20. The extension structure 2041 is provided with a diverter hole 201, and the diverter hole 201 is concentrically arranged with the first connecting tube 200.

[0064] Specifically, by providing a shell 10 with an expansion cavity 103, the refrigerant can be quickly introduced into each diversion hole 201 of the plate body 20, which helps to improve the flow effect of the refrigerant. At the same time, by providing a plug-in portion 204 on the plate body 20 so as to be adaptable and connected with the first connecting pipe 200, the contact area between the first connecting pipe 200 and the plate body 20 is effectively increased, and the connection strength between the distributor 100 and the first connecting pipe 200 is improved, which helps to solve the problem of poor overlap between the existing distributor and the distribution pipe. In addition, it also helps to solve the problem of centering between multiple accessories during matching and provides convenience for subsequent welding. At this time, the diversion component 1000 can adopt both plug-in and welding connection methods to further improve the connection strength between the distributor 100 and the first connecting pipe 200.

[0065] Furthermore, the provision of the plug-in portion 204 not only provides a positioning function for the plug-in connection of the first connecting tube 200, but also eliminates the need for a cover plate, simplifies the structure of the diverter assembly 1000, improves welding reliability, and facilitates improved assembly of the diverter assembly 1000. Furthermore, the provision of the plug-in portion 204 also helps disrupt the flow direction of the refrigerant, thereby improving the mixing effect of the refrigerant.

[0066] It should be understood that the dispenser 100 includes a housing 10 and a plate 20. Figure 2 、 Figure 3 and Figure 6 As shown, the shell 10 is a semi-spherical structure, and the interior of the shell 10 defines a diverter chamber. In this embodiment, the diverter chamber includes an expansion chamber 103 and a mounting chamber 104. The expansion chamber 103 is provided with an inflow hole 111 and a mounting chamber 104 at both ends. From the direction of the inflow hole 111 facing the mounting chamber 104, that is, the flow direction of the refrigerant, the inner diameter of the expansion chamber 103 gradually increases. At this time, the minimum inner diameter of the expansion chamber 103 is the same as the aperture of the inflow hole 111, and the maximum inner diameter of the expansion chamber 103 is the same as the aperture of the mounting chamber 104. The mounting chamber 104 is connected to the outside and forms an opening of the diverter chamber. The refrigerant entering the expansion chamber 103 from the inflow hole 111 changes the flow direction of the refrigerant due to the change in the flow space. On the one hand, the refrigerant can be mixed in the expansion chamber 103, thereby improving the mixing effect. On the other hand, the change in the aperture of the expansion cavity 103 can guide the flow of the refrigerant, and further cooperate with the diversion hole 201 to ensure that the refrigerant flows to the diversion hole 201 evenly and quickly.

[0067] In this embodiment, the plate body 20 is a circular plate-shaped structure, and the plate body 20 is suitable for being set in the installation cavity 104. At this time, the plate body 20 and the inflow hole 111 are suitable for being set on opposite sides of the expansion cavity 103, and the axis of the plate body 20 and the axis of the inflow hole 111 are located in the same straight line. At the same time, a plurality of diversion holes 201 are provided on the plate body 20, and the plurality of diversion holes 201 are arranged around the axis of the plate body 20 as the center. Each diversion hole 201 is connected to a corresponding first connecting pipe 200, so as to play a role in regulating flow distribution, and the diversion hole 201 is concentrically arranged with the first connecting pipe 200. By limiting the axis of the plate body 20 and the axis of the inflow hole 111 to be located in the same straight line, and cooperating with the structure of the expansion cavity 103, it can be further ensured that the refrigerant can flow evenly to each diversion hole 201, thereby achieving the effect of refrigerant diversion and ensuring the sameness of the refrigerant.

[0068] It should be noted that in this embodiment, the housing 10 includes a main body (not shown) and a mounting portion 12. The main body defines an expansion chamber 103 for diverting and mixing the refrigerant. The mounting portion 12 is located on one side of the main body and is used to mount the plate 20 or other components. The mounting portion 12 defines a mounting chamber 104, the aperture of which is the same as the maximum inner diameter of the expansion chamber 103.

[0069] Furthermore, in this embodiment, the housing 10 can be manufactured by spinning, coil welding, or stamping at both ends. Besides being configured as the aforementioned hemispherical structure, the housing 10 can also be configured in other shapes, such as a circular tube, a square tube, etc., to ensure that the expansion cavity 103 and the plate 20 are securely mounted. Optionally, the plate 20 is secured to the mounting cavity 104 of the housing 10 by welding.

[0070] Furthermore, the side (top) surface of the plate 20 facing away from the expansion cavity 103 serves as the welding surface. When the plug-in portion 204 is connected to the first connecting tube 200, if the first connecting tube 200 is sleeved onto the outside of the plug-in portion 204, the welding surface is welded to the end of the first connecting tube 200; if the first connecting tube 200 is inserted into the inside of the plug-in portion 204, the welding surface is welded to the circumference of the first connecting tube 200. The provision of the extension structure 2041 disrupts the flow of the refrigerant, thereby improving the mixing effect of the refrigerant.

[0071] In this embodiment, the first connecting tube 200 has a straight section that mates with the plug-in portion 204, and the straight section is concentric with the diversion hole 201. The straight section is a rigid structure, meaning that it is generally not susceptible to bending. This arrangement further ensures the fit between the first connecting tube 200 and the plug-in portion 204, facilitating subsequent welding processes.

[0072] Furthermore, the plug portion 204 is configured as a hole, and one end of the first connecting tube 200 is inserted into the plug portion 204. The extension structure 2041 is located within the expansion cavity 103 and includes a limit plate 2042 disposed parallel to the plate body 20. The limit plate 2042 abuts against the first connecting tube 200, and the diversion hole 201 is provided on the limit plate 2042.

[0073] Specifically, by setting the plug-in portion 204 to be hole-shaped, one end of the first connecting tube 200 can be inserted into the interior of the plug-in portion 204, thereby providing a connection basis for subsequent welding. Moreover, the extension structure 2041 is located inside the expansion cavity 103, which can disrupt the flow direction of the refrigerant in the expansion cavity 103, thereby further improving the mixing effect of the refrigerant. At the same time, the setting of the limiting plate 2042 can achieve its abutment with the end of the first connecting tube 200. On the one hand, it can limit the insertion depth of the first connecting tube 200 and improve the positioning effect of the first connecting tube 200. On the other hand, the limiting plate 2042 serves as the basis for the opening of the diverter hole 201, and the diverter hole 201 is concentrically arranged with the first connecting tube 200, which helps to further improve the mixing effect of the refrigerant.

[0074] It is important to understand that if Figures 3 to 7 As shown, the plate body 20 is provided with a plurality of plug-in parts 204, and the plug-in parts 204 are configured as holes. An extension structure 2041 is protrudingly provided on one end surface of the plate body 20 and formed with the plug-in part 204. The extension structure 2041 has a limiting plate 2042, and the limiting plate 2042 is provided with a diversion hole 201. The limiting plate 2042 and the diversion hole 201 are concentrically arranged. In this embodiment, the plug-in part 204 is configured as a circular hole, and the first connecting tube 200 is inserted into the interior of the plug-in part 204 and abuts against the limiting plate 2042. When the plate body 20 is set in the mounting portion 12 of the shell 10, the extension structure 2041 is located inside the expansion cavity 103. The aperture of the diversion hole 201 is smaller than the inner diameter of the first connecting tube 200. The provision of the extension structure 2041 and the limitation of the aperture of the diversion hole 201 help to achieve multiple changes in the local flow direction of the refrigerant, thereby improving the mixing effect of the refrigerant.

[0075] It should be noted that the thickness of the plate body 20 is two to four times the depth of the extension structure 2041. Furthermore, the extension structure 2041 is spaced apart from the inner wall of the expansion cavity 103. The provision of the extension structure 2041 further enhances the structural strength of the plate body 20 and helps ensure the insertion depth of the first connecting tube 200, thereby improving the installation of the first connecting tube 200 and facilitating welding.

[0076] In addition, the board 20 is disposed in the mounting portion 12 of the housing 10, that is, the board 20 is accommodated in the mounting cavity 104. Figure 3 and Figure 6 As shown, the side of the plate body 20 facing away from the expansion cavity 103 is spaced apart from the end face of the housing 10. When the first connecting tube 200 is inserted into the plate body 20, a welding slit is formed between the first connecting tube 200 and the inner wall of the mounting portion 12, which helps to further improve the welding effect, thereby ensuring the fixing effect of the first connecting tube 200 and the assembly effect of the dispenser 100.

[0077] Furthermore, a protrusion 2043 is provided on the limiting plate 2042 , and the protrusion 2043 is arranged along the circumference of the diversion hole 201 .

[0078] Specifically, the provision of raised portions 2043 on the limiting plate 2042 further alters the refrigerant flow direction and enhances the refrigerant turbulence. Furthermore, the provision of raised portions 2043 along the circumference of the diverter hole 201 helps increase the thickness of the diverter hole 201. This not only helps ensure the effectiveness of the diversion and its regulation, but also effectively prevents blockage of the diverter hole 201 during welding.

[0079] It is important to understand that if Figure 6 and Figure 7 As shown, a protrusion 2043 is provided on the side of the limiting plate 2042 facing away from the expansion cavity 103, that is, the protrusion 2043 is provided inside the plug-in portion 204. Optionally, the protrusion 2043 is provided as an annular structure and is provided along the circumference of the diverter hole 201, which helps to increase the thickness of the diverter hole 201 to ensure effective diversion and effectively prevent the diverter hole 201 from being blocked during welding. Moreover, the provision of the protrusion 2043 can also enable the refrigerant to form a swirl portion when entering the first connecting pipe 200 through the diverter hole 201, thereby further improving the mixing effect of the refrigerant and the flow rate of the refrigerant.

[0080] It should be noted that, in addition to being configured as an annular structure, the raised portion 2043 may also be configured as a plurality of raised portions, and the plurality of raised portions are spaced apart along the circumference of the diversion hole 201 . Such a configuration is also conducive to the adjustment of the diversion.

[0081] In addition, the above-mentioned plug-in part 204 and the diversion hole 201 are made by stamping, and at this time, the plug-in part 204 is a sinking structure. With such a setting, not only the upper cover plate can be eliminated, but also a sinking platform can be pre-punched on the plate body 20 to serve as the welding lap surface of the first connecting pipe 200, thereby helping to simplify the component structure and improve welding reliability.

[0082] Furthermore, the plug-in portion 204 is configured to be columnar, the extension structure 2041 is disposed on a side of the plate body 20 away from the expansion cavity 103 , and the first connecting tube 200 is sleeved on the extension structure 2041 .

[0083] Specifically, in addition to configuring the plug portion 204 as the aforementioned hole-like structure, the plug portion 204 can also be configured as a column. This not only helps to improve the structural strength of the plate body 20, but also allows the first connecting tube 200 to be sleeved onto the extension structure 2041 of the plug portion 204. In this case, the end face of the first connecting tube 200 is abutted against one end face of the plate body 20, providing a connection foundation for subsequent welding. Simultaneously, the diverter hole 201 passes through the plate body 20 to connect the expansion cavity 103 with the first connecting tube 200, thereby ensuring the flow of refrigerant.

[0084] It is important to understand that if Figures 8 to 10 As shown, the plate body 20 is provided with a plurality of plug-in portions 204, each of which is a columnar structure. An extension structure 2041 protrudes from one end surface of the plate body 20 and forms the plug-in portion 204. When the plate body 20 is installed on the housing 10, the extension structure 2041 is located on the side of the plate body 20 facing away from the expansion cavity 103. At this time, the first connecting tube 200 is sleeved on the extension structure 2041, and the diverter hole 201 passes through the plate body 20, connecting the expansion cavity 103 and the first connecting tube 200. The provision of the extension structure 2041 helps to enhance the structural strength of the plate body 20. At the same time, the sleeved connection between the first connecting tube 200 and the plate body 20 helps ensure the installation of the first connecting tube 200 and facilitates welding.

[0085] It should be noted that the plate 20 is disposed in the mounting portion 12 of the housing 10, that is, the plate 20 is accommodated in the mounting cavity 104. Figure 9 As shown, the thickness of the plate 20 is the same as the depth of the mounting cavity 104. At this point, the side of the plate 20 facing away from the expansion cavity 103 is coplanar with the end face of the housing 10. At this point, the welding position of the plate 20 to the housing 10 and the welding position of the plate 20 to the first connecting pipe 200 are coplanar. This helps to improve welding convenience and ensure the assembly effect of the distributor 100.

[0086] Furthermore, a flow disturbance cavity 20411 is formed on a side of the plug-in portion 204 facing the expansion cavity 103 . The inner diameter of the flow disturbance cavity 20411 is larger than the aperture of the diversion hole 201 and smaller than the inner diameter of the first connecting pipe 200 .

[0087] Specifically, the provision of the flow-turbulating chamber 20411 helps increase the size of the turbulent space, thereby improving the refrigerant mixing effect. By limiting the inner diameter of the flow-turbulating chamber 20411 to be larger than the aperture of the diverter hole 201 and smaller than the inner diameter of the first connecting tube 200, the flow direction of the refrigerant is further disrupted, thereby improving the refrigerant mixing effect.

[0088] It is important to understand that if Figure 9 and Figure 10As shown, a flow disturbance chamber 20411 is defined on the side of the plug-in portion 204 facing the expansion chamber 103. When the plate body 20 is positioned within the mounting chamber 104, the flow disturbance chamber 20411 and the expansion chamber 103 cooperate to form a flow disturbance space, thereby enhancing the flow diversion and flow disturbance effects of the dispenser 100. Furthermore, the inner diameter of the flow disturbance chamber 20411 is slightly smaller than the inner diameter of the first connecting tube 200. "Slightly smaller" means that the inner diameter of the flow disturbance chamber 20411 is 75% to 95% of the inner diameter of the first connecting tube 200. Specifically, the inner diameter of the flow disturbance chamber 20411 is 75%, 80%, 85%, 90%, or 95% of the inner diameter of the first connecting tube 200. The inner diameter of the flow disturbance chamber 20411 is 2 to 4 times the inner diameter of the first connecting tube 200. Optionally, the inner diameter of the flow disturbance chamber 20411 is 2 times the inner diameter of the first connecting tube 200. By limiting the inner diameter of the flow-turbulating cavity 20411 to be larger than the diameter of the diverter hole 201 and smaller than the inner diameter of the first connecting tube 200, the refrigerant can change its flow direction after entering the first connecting tube 200 due to the increased flow space, thereby helping to improve the refrigerant mixing effect. Moreover, because the diverter hole 201 is arranged concentrically with the first connecting tube 200, the refrigerant flow is more uniform, ensuring a better mixing effect.

[0089] It should be noted that in this embodiment, the provision of the spoiler cavity 20411 forms a limit plate 2042 on the plug-in portion 204 that is parallel to the plate body 20. Furthermore, a protrusion 2043 is provided on the side of the limit plate 2042 that faces away from the plate body 20. In this case, the protrusion 2043 is provided on the outside of the plug-in portion 204. Optionally, the protrusion 2043 is the same as the above-described protrusion 2043 and will not be described in detail herein.

[0090] In addition, in addition to being arranged on the side of the plug-in part 204 facing the expansion chamber 103, the spoiler chamber 20411 can also be set as two, and along the vertical direction, the two spoiler chambers 20411 are correspondingly arranged on the two side surfaces of the plug-in part 204. At this time, the above-mentioned limiting plate 2042 is formed between the two spoiler chambers 20411. The above-mentioned structure is not shown in the figure. The setting of the two spoiler chambers 20411 can cooperate with each other to further enhance the spoiler effect and improve the mixing effect of the refrigerant.

[0091] Furthermore, the plate body 20 includes a base material and a welding piece that are connected to each other. The base material and the welding piece are integrally formed and define a plug-in portion 204 . The welding piece abuts against the first connecting pipe 200 .

[0092] Specifically, by configuring the plate body 20 as a base material and a welding piece, the base material and the welding piece can be integrally formed by stamping to form the plug-in portion 204. After the connecting pipe is inserted into or sleeved onto the extension structure 2041, the welding of the first connecting pipe 200 to the plate body 20 can be performed without adding solder or a welding ring, which helps to simplify the subsequent construction process.

[0093] It should be understood that in this embodiment, the base material and the welding piece are integrally formed by stamping, which simplifies the manufacturing method. Furthermore, the welding piece is located on the side of the plate body 20 facing the first connecting tube 200. This allows the first connecting tube 200 and the plate body 20 to be directly welded as a whole without the need for solder, which helps simplify subsequent assembly or connection processes. Furthermore, the material of the welding piece is consistent with that of the first connecting tube 200, thereby ensuring a better welding effect.

[0094] Furthermore, the first connecting pipe 200 is a rigid member. Specifically, by defining the first connecting pipe 200 as a rigid member, it is helpful to realize the automated welding of the first connecting pipe 200 and the plate body 20, and to ensure the structural strength of the first connecting pipe 200. Since multiple first connecting pipes 200 can be connected to multiple connection ports of the first heat exchanger 2000 respectively, it is helpful to realize the automated welding of the first connecting pipes 200 and the first connecting pipes 200 and the first heat exchanger 2000, thereby helping to prevent the problem of the first connecting pipe 200 rebounding after connection.

[0095] It should be understood that in this embodiment, one end of the first connecting tube 200 is connected to the plug portion 204, and the other end of the first connecting tube 200 is provided with a first adapter 60. The first connecting tube 200 is a rigid part, and in this case, a rigid part refers to a part that is not easy to bend under normal circumstances. Optionally, the first connecting tube 200 is a metal part, and its material can be aluminum, magnesium alloy, stainless steel, carbon steel, brass, etc. Figure 2 As shown, multiple first connecting tubes 200 extend along different preset paths. At this point, the ends of the first connecting tubes 200 that connect to the plug-in portion 204 define the aforementioned straight segment. By configuring the tube body as a rigid member, the first connecting tubes 200 and the plug-in portion 204 are easily connected and welded together, thereby effectively preventing the first connecting tubes 200 from springing back after being inserted into the heat exchanger. The first connecting tubes 200 have a simple overall structure and are easily processed and formed, which helps reduce manufacturing costs. They also reduce the overall dimensions of the distributor 100, requiring less space for the structure, saving design space, and achieving a lightweight design.

[0096] In this embodiment, one end of the first adapter 60 is inserted into the first connecting tube 200, and the first adapter 60 is adapted to connect to the connection port of the first heater. Connection methods include, but are not limited to, screw connection, clamping connection, snap connection, riveting, bonding, welding, etc. Optionally, the first adapter 60 is fixed to the connection port by welding.

[0097] It should be noted that the material of the first adapter 60 is the same as that of the connecting port, which helps improve the connection between the first connector and the connecting port, thereby ensuring the stability of the connection. The material of the first adapter 60 and the first connecting tube 200 can be the same or different, and no further restrictions are imposed here. Optionally, the first adapter 60 is made of brass, stainless steel, etc.

[0098] Furthermore, the diverter assembly 1000 further includes a diverter cone 30 , which is disposed on the plate body 20 , and the axis of the diverter cone 30 is located on the same straight line as the axis of the inflow hole 111 .

[0099] Specifically, the setting of the diverter cone 30, on the one hand, can also cooperate with the structure of the expansion chamber 103 to re-mix the gas-liquid refrigerant flowing into the expansion chamber 103 from the inlet pipe 301, so as to help improve the mixing effect of the distributor 100; on the other hand, a diversion surface can be formed in the diverter chamber so that the refrigerant can flow evenly to each diverter hole 201 under the action of the diverter cone 30 after entering the expansion chamber 103, thereby ensuring the diversion effect of the diverter component 1000.

[0100] It is important to understand that if Figure 3 、 Figure 6 and Figure 9 As shown, a diverter cone 30 is provided on the plate body 20, and the cone line of the diverter cone 30 is located in the same straight line as the axis of the inflow hole 111, and at this time, a plurality of diverter holes 201 are arranged at intervals along the circumference of the diverter cone 30, and are arranged at intervals from the diverter cone 30. In this embodiment, the diverter cone 30 has a small diameter end and a large diameter end, wherein the large diameter end is connected to the plate body 20. Optionally, the small diameter end is provided in the expansion cavity 103 and is provided corresponding to the inflow hole 111. At this time, the refrigerant entering the expansion cavity 103 from the inflow hole 111 will impact the small diameter end of the diverter cone 30, and under the action of the cone surface of the diverter cone 30, it will flow to each diverter hole 201, which helps to ensure the uniformity and rapidity of the refrigerant flow.

[0101] It should be noted that, in addition to placing the small-diameter end in the expansion chamber 103, the small-diameter end can also be placed on the side away from the expansion chamber 103, that is, the small-diameter end is placed inside the installation chamber 104. In this case, the internal hollowing of the diverter cone 30 forms a conical flow guide space. The refrigerant entering the expansion chamber 103 from the inflow hole 111 will impact the small-diameter end of the diverter cone 30 and, under the action of the conical surface of the diverter cone 30, flow to each diverter hole 201. Since the inflow hole 111 and the small-diameter end are located on the same straight line, the diversion space is on the same horizontal plane, and the pressure at each location is the same or similar, which helps to ensure the uniformity of the refrigerant flow.

[0102] In this embodiment, the diverter cone 30 and the plate body 20 are split structures. Specifically, a avoidance hole 203 is opened in the middle of the plate body 20, and the diverter cone 30 is arranged in the avoidance hole 203, and the small diameter end of the diverter cone 30 is located in the expansion cavity 103. The diverter cone 30 is set in the avoidance hole 203 of the plate body 20, and the diverter cone 30 and the plate body 20 are welded and fixed. Such a setting, on the one hand, helps to adjust the insertion depth of the diverter cone 30, ensure the distance between the diverter cone 30 and the inflow hole 111, and helps to improve the applicability of the distributor 100 and adjust the diversion effect. On the other hand, the diverter cone 30 can be set to different structures such as a cone, a triangular pyramid, a square pyramid, a pentagonal pyramid, etc. to adapt to the number of diverter holes 201 and ensure the diversion effect. At the same time, it helps to improve the diversity of the diverter cone 30, thereby improving the applicability of the distributor 100.

[0103] It should be understood that, as shown in the figure, the diverter cone 30 includes a cone 31, an extension section 32, and a second flange 33. From the direction of the inflow hole 111 toward the plate body 20, the cone 31, the extension section 32, and the second flange 33 are connected in sequence. Among them, the extension section 32 is adapted to the inner wall of the avoidance hole 203. Optionally, the cone 31 is arranged inside the expansion cavity 103, and the second flange 33 is fitted and connected to the side of the plate body 20 facing away from the expansion cavity 103. By providing the extension section 32 so that it can be connected in coordination with the avoidance hole 203, it is helpful to achieve a sealed connection between the plate body 20 and the diverter cone 30. At the same time, the provision of the second flange 33, on the one hand, helps to further improve the sealing effect between the plate body 20 and the diverter cone 30; on the other hand, it can also improve the assembly efficiency of the plate body 20 and the diverter cone 30, thereby improving the assembly effect of the distributor 100; thirdly, the second flange 33 can increase the welding area between the diverter cone 30 and the plate body 20, which helps to further improve the connection effect between the diverter cone 30 and the plate body 20.

[0104] It should be pointed out that when the cone of the diverter cone 30 is set in the installation cavity 104, the second flange 33 is fitly connected to the side of the plate body 20 facing the expansion cavity 103. At this time, the welding position of the diverter cone 30 and the plate body 20 is the connection between the cone and the plate body 20. Such a setting helps to reduce the impact of welding on the flow of refrigerant, so as to ensure the effect of the diverter cone 30.

[0105] Alternatively, the diverter cone 30 can be composed solely of the cone 31 and the extension 32. In this case, the end surface of the extension 32 facing away from the cone 31 can optionally be coplanar with the mounting surface to facilitate welding. Alternatively, the end surface of the extension 32 facing away from the cone 31 can be parallel to the mounting surface, with the extension 32 extending outward to the side of the plate 20 facing away from the expansion cavity 103, or positioned within the avoidance hole 203.

[0106] In some other embodiments of the present application, the diverter cone 30 and the plate body 20 are integrally formed. This integrally formed component helps reduce the difficulty of manufacturing and assembling the distributor 100. Alternatively, the diverter cone 30 and the plate body 20 are integrally stamped. This provides a simple structure and facilitates fabrication. In this case, the hollowed-out interior of the diverter cone 30 helps reduce the manufacturing cost of the distributor 100 while ensuring the diversion effect of the diverter cone 30.

[0107] Furthermore, the distributor 100 has a first inserting portion 11 , which defines an inflow hole 111 . Meanwhile, the flow diversion assembly 1000 further includes a second connecting pipe 300 , which is sleeved on the outside of the first inserting portion 11 .

[0108] Specifically, by providing the first inserting portion 11 on the distributor 100 so as to be plug-connected with the second connecting pipe 300 , it helps to reduce the difficulty of assembling the diverter assembly 1000 and improve the assembly efficiency of the diverter assembly 1000 .

[0109] It is important to understand that if Figure 3 、 Figure 6 and Figure 9 As shown, the bottom of the distributor 100 protrudes outward and is formed with a first plug-in portion 11. The interior of the first plug-in portion 11 defines an inflow hole 111. At the same time, the second connecting pipe 300 is sleeved on the outside of the first plug-in portion 11. In this embodiment, the second connecting pipe 300 includes an inlet pipe 301. The interior of the inlet pipe 301 defines a cavity, which includes an incident cavity 101 and a connecting cavity (not shown in the figure). The incident cavity 101 is used for the inflow of refrigerant, and the connecting cavity is sleeved on the outside of the first plug-in portion 11 so that the refrigerant flowing through the incident cavity 101 enters the expansion cavity 103 through the inflow port.

[0110] In this embodiment, the inner diameter of the incident cavity 101 is larger than the inner diameter of the connecting cavity. At the same time, a transition cavity (not shown in the figure) is provided between the incident cavity 101 and the connecting cavity to ensure that the refrigerant can enter the inflow hole 111. At this time, along the flow path of the refrigerant, the inlet pipe 301 cooperates with the shell 10 to form the incident cavity 101, the steady flow cavity 102 (inflow hole 111), and the expansion cavity 103 connected in sequence. By limiting the inner diameters of the incident cavity 101, the steady flow cavity 102, and the expansion cavity 103, the inlet pipe 301 cooperates with the shell 10 to form a Venturi tube structure, so as to increase the flow rate by reducing the flow area, thereby generating a low-pressure area in the throat. The change in the refrigerant flow rate helps to further improve the refrigerant mixing effect and increase the flow rate of the refrigerant flowing to each diversion hole 201, thereby ensuring the diversion effect of the diversion component 1000.

[0111] It should be noted that, in addition to inserting the inlet tube 301 onto the outside of the first inserting portion 11, the end of the inlet tube 301 closest to the expansion chamber 103 can also be inserted into the interior of the inflow hole 111. Of course, in addition to this insertion method, other methods such as threaded connection, flange connection, and welding can also be used. Optionally, multiple welds can be provided at the connection between the inlet tube 301 and the first inserting portion 11 to further enhance the connection between the inlet tube 301 and the first inserting portion 11.

[0112] In addition, the inlet pipe 301 and the housing 10 can be configured as an integrally formed part. This configuration helps to improve the structural strength of the diverter assembly 1000 and improve the assembly efficiency of the diverter assembly 1000.

[0113] Furthermore, the second connecting tube 300 also includes an inlet tube 301 and a second adapter 70. The inlet tube 301 is sleeved onto the first inserting portion 11 and has an inlet cavity 101. The inner diameter of the inlet cavity 101 is larger than the inner diameter of the inlet hole 111. The second adapter 70 is inserted into the end of the inlet tube 301 facing away from the inlet hole 111.

[0114] Specifically, by providing the inlet pipe 301, the flow-dividing assembly 1000 can form a Venturi tube structure at the connection between the second connecting pipe 300 and the housing 10, thereby increasing the flow rate of the refrigerant after entering the distributor 100 from the second connecting pipe 300, and cooperating with the diverter cone 30 to improve the diversion and mixing effects of the refrigerant. At the same time, the provision of the second adapter 70 enables the inlet pipe 301 to communicate with other connecting structures, and by changing the material of the second adapter 70, the inlet pipe 301 and the other connecting structures can be plugged in and fixed by welding. There is a need to improve the applicability of the inlet pipe 301, and thus improve the applicability of the flow-dividing assembly 1000.

[0115] It should be understood that the second connecting pipe 300 includes an inlet pipe 301 and a connecting pipe (not shown in the figure). In this embodiment, the inlet pipe 301 and the connecting pipe are connected by a second adapter 70. The second adapter 70 is inserted into the inlet pipe 301, and the second adapter 70 and the inlet pipe 301 are made of the same material. By providing a welding point at the connection between the second adapter 70 and the inlet pipe 301, the connection effect between the second adapter 70 and the inlet pipe 301 can be further improved. The provision of the inlet pipe 301 can cooperate with the shell 10 to form a Venturi tube structure, and the provision of the second adapter 70 can further improve the applicability of the diverter assembly 1000, so that there is a better connection effect between the inlet pipe 301 and the connecting pipe, ensuring the stability of the refrigerant transmission and the service life of the diverter assembly 1000.

[0116] It should be noted that in addition to the above connection method, the connecting pipe and the inlet pipe 301 can be directly connected. Optionally, the connecting pipe is screwed to the outer circumference of the inlet pipe 301, or the connecting pipe and the inlet pipe 301 are made of the same material so that the connecting pipe and the inlet pipe 301 can be welded and fixed.

[0117] The second aspect of this practical method also proposes a HVAC equipment 1, which includes a first heat exchanger 2000, a second heat exchanger 3000 and a diversion component 1000. The diversion component 1000 is the above-mentioned diversion component 1000, and at this time, the first connecting pipe 200 is connected to the first heat exchanger 2000, and the distributor 100 is connected to the second heat exchanger 3000.

[0118] Compared with the prior art, the HVAC equipment 1 proposed in the present invention has the technical advantages possessed by the above-mentioned diversion component 1000, which will not be described in detail here.

[0119] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. 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. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
