Description

Technical Field

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

[0002] For HVAC equipment, there are generally two modes: cooling mode and heating mode. In this case, cooling mode and heating mode refer to the indoor heat exchanger. When the indoor heat exchanger is in cooling mode or heating mode, the outdoor heat exchanger is in heating mode or cooling mode respectively.

[0003] In cooling mode, the compressor compresses the low-temperature, low-pressure refrigerant to a high-temperature, high-pressure state. After flowing into the outdoor heat exchanger, it condenses into a high-pressure, medium-temperature liquid refrigerant. This liquid refrigerant then passes through a throttling device to become a low-temperature, low-pressure two-phase refrigerant. Before entering the indoor heat exchanger, the two-phase refrigerant flows through a distributor. The distributor allocates the two-phase refrigerant according to the refrigerant demand in different flow paths before it enters the indoor heat exchanger for heat exchange, achieving the cooling effect. In this mode, the outdoor heat exchanger acts as the condenser, and the indoor heat exchanger acts as the evaporator. The low-temperature, low-pressure refrigerant after heat exchange eventually enters the compressor's return gas end for subsequent circulation. In heating mode, the compressed refrigerant first enters the indoor heat exchanger for condensation. In this mode, the indoor heat exchanger acts as the condenser, and 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, most distributors use stepped hole structures to install connecting pipes and form welding lap surfaces. To ensure welding quality, a certain lap depth or lap area is generally required. This necessitates that the stepped holes be quite deep, resulting in a heavier distributor and requiring more installation space when connecting the distributor to the connecting pipe, which is detrimental to the assembly of the diversion components. Conversely, reducing the depth of the stepped holes would lead to poor reliability of the lap structure between the distributor and the connecting pipe. Summary of the Invention

[0005] The purpose of this invention is to at least solve the problem of poor connection between existing distributors and connecting pipes. This purpose is achieved through the following technical solution:

[0006] A first aspect of the present invention provides a shunt assembly comprising:

[0007] A distributor having an inlet orifice and a plurality of branch orifices, the plurality of branch orifices being in communication with the inlet orifice;

[0008] A connector is disposed on the distributor and has multiple insertion holes, each insertion hole corresponding to and connected to one of the diversion holes;

[0009] The first connecting tube is connected to the distributor through the connector, and one end of the first connecting tube is inserted into each of the plug holes and the diversion hole is connected to the first connecting tube.

[0010] The diversion assembly of this invention includes a distributor, a connector, and a first connecting pipe. By providing the connector on the distributor for inserting the first connecting pipe and ensuring communication between the first connecting pipe and the diversion hole of the distributor, the connector with the insertion hole provides positioning for the insertion of the first connecting pipe, thus helping to solve the alignment problem between multiple components (the first connecting pipe and the diversion hole). Furthermore, it reduces the structural requirements of the distributor for the insertion of the first connecting pipe, significantly reducing the weight of the distributor and achieving lightweighting of the diversion assembly, thereby reducing component costs. Thirdly, by extending the depth of the insertion hole, the contact area between the connector and the first connecting pipe is increased, thereby improving the connection effect between the distributor and the first connecting pipe and enhancing subsequent welding strength, thus helping to solve the problem of poor connection effect between existing distributors and connecting pipes.

[0057] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0058] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also mean including the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0059] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0060] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.

[0061] like Figures 1-10 As shown, this invention proposes a flow-diverting assembly 1000 for use in a heating, ventilation, and air conditioning (HVAC) system 1. Specifically, the HVAC system 1 may include a compressor 4000, a valve structure, a first heat exchanger 2000, and a second heat exchanger 3000 connected in series. The compressor 4000 is used to compress refrigerant. The refrigerant compressed by the compressor 4000 flows sequentially through the second heat exchanger 3000 and the first heat exchanger 2000, and finally flows back to the compressor 4000. The valve structure includes a four-way valve 6000. The four-way valve 6000 has four ports, two of which are connected to the output and input ends of the compressor 4000, respectively, and the other two ports are connected to the input end of the second heat exchanger 3000 and the output end of the first heat exchanger 2000, respectively.

[0062] The first heat exchanger 2000 and the second heat exchanger 3000 enable the HVAC system 1 to switch between evaporator and condenser functions, i.e., heating mode and cooling mode. In this configuration, one of the heat exchangers 2000 and 3000 is located outside the target space as an outdoor unit, while the other is installed inside the target space as an indoor unit. The outdoor and indoor units work together to form a circulation path, enabling the HVAC system 1 to provide cooling, heating, dehumidification, and air purification to the target space, thereby achieving a comfortable environment. The HVAC system 1 can have one outdoor unit and multiple indoor units; this embodiment does not impose a specific limitation on this.

[0063] In this embodiment, the HVAC equipment 1 is an air conditioner (in other embodiments of the present invention, the HVAC equipment 1 includes, but is not limited to, multi-split air conditioners, heat pumps, water heaters, swimming pool machines, etc.), the first heat exchanger 2000 is an evaporator, and the second heat exchanger 3000 is a refrigerant. The first heat exchanger 2000 and the second heat exchanger 3000 are connected by a flow distribution assembly 1000 to achieve the distribution of refrigerant from the main gas / liquid collection pipe to multiple heat exchanger blocks. At this time, the valve structure also includes a refrigerant throttling valve 5000, which is connected and disposed between the flow distribution assembly 1000 and the second heat exchanger 3000.

[0064] In terms of overall design, such as Figures 1-10 As shown, the diversion assembly includes a distributor 100, a connector 40, and a first connecting pipe 200. The distributor 100 has an inlet 111 and multiple diversion holes 201, which communicate with the inlet 111. The connector 40 is disposed on the distributor 100 and has multiple insertion holes 410, each corresponding to a diversion hole 201. The first connecting pipe 200 is connected to the distributor 100 via the connector 40, with one end of the first connecting pipe 200 inserted into each insertion hole 410, and the diversion holes 201 communicating with the first connecting pipe 200.

[0065] Specifically, by providing a connector 40 on the distributor 100 for inserting the first connecting pipe 200 and ensuring communication between the first connecting pipe 200 and the diversion hole 201 of the distributor 100, the connector 40 with the insertion hole 410 provides positioning for the insertion of the first connecting pipe 200, thus helping to solve the alignment problem between multiple components (the first connecting pipe 200 and the diversion hole 201) during mating. Furthermore, it reduces the structural requirements of the distributor 100 for the insertion of the first connecting pipe 200, significantly reducing the weight of the distributor 100 and achieving lightweighting of the distributor 100, thereby achieving lightweighting of the diversion component and reducing component costs. Thirdly, by extending the depth of the insertion hole 410, the contact area between the connector 40 and the first connecting pipe 200 is increased, thereby improving the connection effect between the distributor 100 and the first connecting pipe 200 and enhancing subsequent welding strength, thus helping to solve the problem of poor connection effect between the existing distributor 100 and the connecting pipe.

[0066] It is necessary to understand that, such as Figure 2 , Figure 3 , Figure 4 and Figure 8 As shown, the distributor 100 has a hemispherical structure. An inlet hole 111 is provided at the bottom of the distributor 100 for the refrigerant to flow in, and multiple diversion holes 201 are provided at the top of the distributor 100, all of which communicate with the inlet hole 111 to allow the refrigerant to flow out of the distributor 100. Combined with... Figure 7 and Figure 10 As shown, the top of the distributor 100 has a mounting surface (not shown in the figure), and the connector 40 is fitted and connected to the mounting surface. At the same time, the connector 40 has multiple insertion holes 410. The first connecting tube 200 is inserted into the insertion holes 410 and fitted and connected to the mounting surface. At this time, the connector 40 can be fixed to the distributor 100 by welding, and the first connecting tube 200 is connected to the connector 40 by welding, thereby realizing the connection between the distributor 100 and the first connecting tube 200.

[0067] It should be noted that in this embodiment, the first connecting pipe 200 and the connector 40 are connected together by welding. At this time, the first connecting pipe 200 has a straight segment that is adapted to connect with the insertion hole 410. The straight segment is a rigid structure, that is, under normal circumstances, the straight segment of the first connecting pipe 200 is not easy to bend. Optionally, the straight segment is made of metal, that is, at least part of the first connecting pipe 200 (the straight segment) is a metal part. This setting can help ensure the fit between the first connecting pipe 200 and the insertion hole 410, and also facilitate subsequent welding and fixing.

[0068] Furthermore, the diameter of the diversion orifice 201 is smaller than the inner diameter of the first connecting pipe 200. Specifically, by limiting the diameter of the diversion orifice 201 to be smaller than the inner diameter of the first connecting pipe 200, the refrigerant, after entering the first connecting pipe 200, changes its flow direction due to the increased flow space, thereby helping to improve the mixing effect of the refrigerant. Optionally, the diameter of the diversion orifice 201 is 0.4 to 0.8 times the inner diameter of the first connecting pipe 200. Optionally, the diameter of the diversion orifice 201 is 0.5 times the inner diameter of the first connecting pipe 200. And because the diversion orifice 201 and the first connecting pipe 200 are concentrically arranged, the flow of the refrigerant is more uniform, and a better mixing effect is ensured.

[0069] In addition, the connection between the connector 40 and the distributor 100 can be made in ways including but not limited to the welding mentioned above, such as screwing, snap-fitting, or other connection methods, as long as the connector 40 can be fixed in the distributor 100.

[0070] Furthermore, the distributor 100 includes a housing 10 and a plate 20, wherein the housing 10 has an expansion cavity 103 communicating with the inlet hole 111, and the expansion cavity 103 has an opening. The plate 20 is disposed on the housing 10 and seals the opening, and the plate 20 is provided with a plurality of diversion holes 201, and the plurality of diversion holes 201 are arranged around the inlet hole 111 as the center.

[0071] Specifically, by defining the expansion cavity 103 in the housing 10 of the distributor 100, the flow rate of the refrigerant after entering the expansion cavity 103 from the inlet hole 111 is slowed down, allowing for preliminary mixing. Simultaneously, by placing the plate 20 at the opening of the housing 10 and providing the diversion holes 201 on the plate 20, the refrigerant from the inlet hole 111 can only flow out through the diversion holes 201. By defining multiple diversion holes 201 arranged around the inlet hole 111, the refrigerant flows from the inlet hole 111 to each diversion hole 201 along the same path, helping to ensure the refrigerant content flowing to each diversion hole 201, thereby ensuring the diversion effect of the distributor 100.

[0072] It is necessary to understand that, such as Figure 3 , Figure 7 and Figure 10As shown, the housing 10 has an overall hemispherical structure. A first insertion portion 11 is provided at the bottom of the housing 10, defining the aforementioned inflow hole 111. The first insertion portion 11 is used to connect with the second connecting pipe 300 described below. Simultaneously, a flow-dividing cavity is defined inside the housing 10, wherein the flow-dividing cavity has an opening. In this embodiment, the flow-dividing cavity includes an expansion cavity 103 and a mounting cavity 104. The inflow hole 111 and the mounting cavity 104 are respectively provided at both ends of the expansion cavity 103. From the direction of the inflow hole 111 towards the mounting cavity 104, i.e., the flow direction of the refrigerant, the inner diameter of the expansion cavity 103 gradually increases. Optionally, the expansion cavity 103 is configured as a hemispherical structure. The minimum inner diameter of the expansion cavity 103 is the same as the diameter of the inflow hole 111, and the maximum inner diameter of the expansion cavity 103 is the aforementioned opening, which is the same as the diameter of the mounting cavity 104. The mounting cavity 104 is connected to the outside and forms the opening of the flow-dividing cavity. The refrigerant entering the expansion chamber 103 from the inlet 111 changes its flow direction due to the altered flow space. This changes the refrigerant's mixing effect within the expansion chamber 103, improving the mixing efficiency. Furthermore, the change in the orifice diameter of the expansion chamber 103 guides the refrigerant flow, which, in conjunction with the diversion orifice 201 described below, ensures a uniform and rapid flow of refrigerant to the diversion orifice 201.

[0073] In this embodiment, the plate 20 has a circular plate structure and is adapted to be disposed in the mounting cavity 104 and to block the opening of the expansion cavity 103. At this time, the plate 20 and the inlet hole 111 are adapted to be disposed on opposite sides of the expansion cavity 103, and the axis of the plate 20 and the axis of the inlet hole 111 are collinear. Simultaneously, the plate 20 has multiple diversion holes 201, which are arranged around the axis of the plate 20. Each diversion hole 201 is connected to a first connecting pipe 200 to regulate flow distribution. The diversion holes 201 and the first connecting pipes 200 are concentrically arranged. By ensuring that the axis of the plate 20 and the axis of the inlet hole 111 are collinear, and in conjunction with the structure of the expansion cavity 103, it is further guaranteed that the refrigerant can flow evenly to each diversion hole 201, ensuring the uniformity of the refrigerant while achieving the effect of refrigerant diversion.

[0074] It should be noted that in this embodiment, the housing 10 includes a main body (not shown in the figure) and a mounting portion 12. The main body defines an expansion cavity 103 for distributing and mixing the refrigerant. The mounting portion 12 is located at one end of the main body and is disposed on opposite sides of the main body corresponding to the first insertion portion 11 for mounting the plate 20 or other components. The mounting portion 12 defines a mounting cavity 104, the inner diameter of which is the same as the maximum inner diameter of the expansion cavity 103.

[0075] Furthermore, the housing 10 can be manufactured by spinning, rolling, or stamping at both ends. Meanwhile, the plate 20 is fixed in the mounting cavity 104 of the housing 10 by welding.

[0076] Additionally, the side of the plate 20 facing away from the expansion cavity 103 is the aforementioned mounting surface. Optionally, the mounting surface and the top end face of the housing 10 are located on the same plane. In another optional embodiment, the mounting surface is parallel to the top end face of the housing 10, and the plate 20 is accommodated inside the mounting cavity 104. In this case, an accommodating space is defined between the mounting surface and the top end of the housing 10 to accommodate a portion of the connector 40, which facilitates the welding and fixing of this portion of the connector 40 to the distributor 100.

[0077] Furthermore, the connector 40 includes a connecting portion 41 and a cylindrical body 42. The connecting portion 41 is fitted and connected to the distributor 100. The cylindrical body 42 is disposed on the connecting portion 41 and is located on the side of the connecting portion 41 opposite to the distributor 100. The cylindrical body 42 defines an insertion hole 410 that passes through the connecting portion 41.

[0078] Specifically, by making the connecting part 41 fit snugly against the distributor 100, a contact point required for welding can be formed between the connecting part 41 and the distributor 100. At this time, by increasing the contact area between the connecting part 41 and the distributor 100, sufficient welding area can be ensured between the connecting part 41 and the distributor 100, thereby improving the connection strength between the connecting part 40 and the distributor 100. The setting of the cylinder 42 not only facilitates the insertion of the first connecting pipe 200, providing convenience for subsequent welding, but also serves as a welding base, improving the connection strength between the cylinder 42 and the first connecting pipe 200.

[0079] It is necessary to understand that, such as Figures 4-10 As shown, in this embodiment, the connecting part 41 and the cylinder 42 are integrally formed. The connecting part 41 is plate-shaped, and one side of the connecting part 41 is attached to the plate 20. At this time, the top surface of the connecting part 41 can cooperate with the inner wall or top surface of the mounting part 12 to form a contact point required for welding, and the peripheral surface of the connecting part 41 can also form a welding surface required for welding with the mounting surface of the plate 20. Meanwhile, the cylinder 42 has a cylindrical structure and forms the insertion hole 410 mentioned above. The first connecting tube 200 is suitable for insertion into the inside of the cylinder 42. The peripheral surface of the first connecting tube 200 can cooperate with the end face of the end of the cylinder 42 away from the connecting part 41 to form a welding surface. Through the welding of the first connecting tube 200 to the cylinder 42 and the welding of the connecting part 41 to the distributor 100, the connection and fixation of the first connecting tube 200 and the distributor 100 can be realized, which helps to improve the structure of the distributor 100 and realize the weight reduction of the distributor 100.

[0080] It should be noted that, due to the setting of the cylinder 42, the insertion depth of the first connecting pipe 200 can be effectively guaranteed or increased, and the thickness requirement of the connecting part 41 for the insertion of the first connecting pipe 200 can be reduced, which helps to reduce the weight of the connecting part 40. Thus, on the basis of ensuring the connection between the first connecting pipe 200 and the distributor 100, the flow distribution component can be made lighter and the component cost can be reduced.

[0081] In some embodiments of this application, there is one connecting part 41 and multiple cylinders 42, and the multiple cylinders 42 are arranged at circumferential intervals along the inlet hole 111.

[0082] Specifically, by defining the connector 40 as having a connecting part 41 and multiple cylinders 42, the structural strength of the connector 40 can be effectively increased. At the same time, by providing a connecting part 41, the connector 41 can be adapted to connect with the distributor 100, so as to achieve the alignment of the insertion hole 410 and the diversion hole 201 when they are mated, thereby achieving the concentric setting of the first connecting pipe 200 and the diversion hole 201, which helps to make the refrigerant flow more uniform and ensure a better mixing effect.

[0083] It is necessary to understand that, such as Figures 3 to 7 As shown, the mounting portion 12 of the housing 10 forms a cylindrical mounting cavity 104, and the connecting portion 41 is configured as a circular plate and is adapted to connect with the mounting cavity 104. At this time, the insertion hole 410 of the cylinder 42 and the diversion hole 201 are concentrically arranged, and when the first connecting pipe 200 is provided in the insertion hole 410, the first connecting pipe 200 and the diversion hole 201 are concentrically arranged. This arrangement helps to solve the alignment problem between multiple accessories (first connecting pipe 200 and diversion hole 201) during the fit. At the same time, multiple cylinders 42 are arranged circumferentially along the inflow hole 111, so that multiple first connecting pipes 200 are arranged circumferentially along the inflow hole 111. With the diversion cone 30 described below, the diversion effect of the distributor 100 can be effectively improved. Optionally, multiple cylinders 42 are arranged at equal intervals along the circumference of the inlet hole 111. On the one hand, this helps to further improve the fit between the first connecting pipe 200 and the diverting cone 30; on the other hand, it can form sufficient welding space to ensure the connection effect between the first connecting pipe 200 and the cylinder 42.

[0084] It should be noted that the periphery of the connecting part 41 and the mounting cavity 104 can be spaced apart. In this case, the connecting part 41 is adapted to connect with the second flange 33 of the diverting cone 30 described below, so as to ensure the concentric arrangement of the insertion hole 410 and the diverting hole 201. In addition, the shape of the connecting part 41 may include, but is not limited to, a circle, such as a square, rhombus, triangle, or pentagon, as long as it can ensure the concentric arrangement of the insertion hole 410 and the diverting hole 201.

[0085] Furthermore, the first end of the distributor 100 is provided with a mounting cavity 104, the connecting part 41 is disposed inside the mounting cavity 104 and is spaced apart from the end face of the first end, and the cylinder 42 is spaced apart from the inner wall of the mounting cavity 104.

[0086] Specifically, by defining the mounting cavity 104 as located at the first end of the distributor 100, and accommodating the connecting portion 41 within the mounting cavity 104 and spaced apart from the end face of the first end, the end face of the first end can be higher than the top surface of the connecting portion 41. This helps prevent solder loss and improves the reliability of the distributor assembly. Simultaneously, the spaced arrangement between the cylinder 42 and the inner wall of the mounting cavity 104 creates a welding gap to accommodate the solder, further enhancing the connection between the connector 40 and the distributor 100.

[0087] It is necessary to understand that, such as Figure 7 As shown, since the housing 10 has a mounting portion 12, the end with the mounting portion 12 is the first end, and the end face of the first end is the first end face. The direction from the inlet hole 111 to the diversion hole 201, i.e., the refrigerant flow direction, is where the connecting portion 41 is located in the middle of the mounting cavity 104, and the welding end of the cylinder 42 and the connecting portion 41 are respectively located on opposite sides of the first end face. The welding end of the cylinder 42 is the end of the cylinder 42 facing away from the connecting portion 41, and is used for welding to the circumferential surface of the first connecting pipe 200. This arrangement allows the welding end of the cylinder 42 to be far from the welding point (contact point) between the connecting portion 41 and the mounting portion 12, facilitating the welding and fixing of the diversion assembly, thereby improving the connection effect between the various parts of the diversion assembly.

[0088] It should be noted that the welding end of the cylinder 42 is spaced apart from the first end face, and the spacing can be optimized according to actual needs. By designing the height or spacing of the cylinder 42, the overlap area between the connector 40 and the first connecting pipe 200 can be effectively increased, which helps to improve welding reliability and enhance welding strength. At the same time, the thickness of the connecting part 41 can be greatly reduced, realizing the weight reduction of the diversion component and reducing the component cost.

[0089] Furthermore, the number of connecting parts 41 is the same as the number of diversion holes 201, and each connecting part 41 is provided with a corresponding cylinder 42.

[0090] Specifically, by limiting the number of connecting parts 41 to be the same as the number of diversion holes 201, the number of connecting parts 41 is multiple. At this time, each connecting part 41 is provided with a corresponding cylinder 42. With this setting, the connecting part 40 can be transformed into a standardized sample that is only related to the pipe diameter specification, which helps to simplify the components of the diversion assembly and improve welding reliability.

[0091] It is necessary to understand that, such as Figures 8 to 10As shown, in this embodiment, the first end face of the mounting part 12 and the top surface of the plate 20 are located on the same plane. Simultaneously, there are multiple connectors 40, and each connector 40 corresponds to one of the multiple diversion holes 201. Each connector 40 includes a cylindrical body 42 and a connecting part 41. The cylindrical body 42 has a circular tube structure, and the connecting part 41 is located at one end of the cylindrical body 42 and extends radially along the cylindrical body 42. The connecting part 41 is fitted and connected to the plate 20. In this case, the connector 40 can be designed according to the pipe diameter of the first connecting pipe 200, the overlapping surface of the welding process (skirt for the connecting part 41), and the depth of the cylindrical body 42, so that the connector 40 forms a standardized sample related to the pipe diameter specification, which helps to simplify the components of the diversion assembly and improve the reliability of welding.

[0092] It should be noted that setting the connector 40 as a standardized sample can, on the one hand, increase the contact area between the connector 41 and the top surface of the plate 20, thereby improving the convenience of welding; on the other hand, it can reduce the correlation between the connector 40 and the distributor 100, thereby improving the applicability of the connector 40 and helping to reduce the manufacturing cost of the diversion assembly.

[0093] Furthermore, in this embodiment, the welding surfaces of the housing 10 and the plate 20, as well as the welding surfaces of the mounting portion 12 and the plate 20, are on the same plane, which helps to improve the convenience of welding and enhances the connection effect between the distributor 100 and the connecting portion 41.

[0094] Furthermore, the diversion assembly also includes a diversion cone 30, which is disposed on the plate 20. The axis of the diversion cone 30 is on the same straight line as the axis of the inlet hole 111. The cone 31 of the diversion cone 30 is located inside the expansion cavity 103. The cone 31 is used to guide the refrigerant from the inlet hole 111 to the diversion hole 201.

[0095] Specifically, by setting a flow divider cone 30 and placing the cone 31 of the flow divider cone 30 inside the expansion cavity 103, a flow guiding surface can be formed in the flow divider cavity. This allows the refrigerant to flow evenly to each flow divider hole 201 after entering the expansion cavity 103, ensuring the flow dividing effect of the flow dividing assembly. At the same time, the setting of the flow divider cone 30 can also work in conjunction with the structure of the expansion cavity 103 to further improve the flow dividing effect of the distributor 100.

[0096] It is necessary to understand that, such as Figure 7 and Figure 10As shown, a flow divider cone 30 is provided on the plate 20. The cone line of the flow divider cone 30 is on the same straight line as the axis of the inlet hole 111. At this time, multiple flow dividers 201 are arranged circumferentially at intervals along the inlet hole 111 and at intervals with the flow divider cone 30. In this embodiment, the flow divider cone 30 has a small-diameter end and a large-diameter end, wherein the large-diameter end is connected to the plate 20. Optionally, the small-diameter end is provided in the expansion cavity 103 and is correspondingly provided to the inlet hole 111. In this case, the refrigerant entering the expansion cavity 103 from the inlet hole 111 will impact the small-diameter end of the flow divider cone 30 and flow to each flow divider hole 201 under the action of the cone surface (drainage surface) of the flow divider cone 30, which helps to ensure the uniformity and speed of refrigerant flow.

[0097] It should be noted that, in addition to placing the small-diameter end in the expansion cavity 103, the small-diameter end can also be placed on the side opposite to the expansion cavity 103, that is, inside the mounting cavity 104. In this case, the internal hollowing-out arrangement of the flow divider cone 30 forms a conical flow guiding space. The refrigerant entering the expansion cavity 103 from the inlet hole 111 will impact the small-diameter end of the flow divider cone 30, and under the action of the conical surface of the flow divider cone 30, it will flow to each flow divider hole 201. Since the inlet hole 111 and the small-diameter end are on the same straight line, the flow guiding space is on the same horizontal plane, and the pressure is the same or similar everywhere, which helps to ensure the uniformity of refrigerant flow.

[0098] It is important to understand that the plate 20 and the diverter cone 30 are integrally formed. By making the diverter cone 30 and the plate 20 integrally formed, the manufacturing and assembly difficulty of the distributor 100 is reduced. Optionally, the diverter cone 30 and the plate 20 are integrally stamped. This results in a simple structure and convenient manufacturing. In this case, the internal hollow design of the diverter cone 30 helps reduce the manufacturing cost of the distributor 100 and ensures the diverter cone 30's guiding effect.

[0099] It should be further understood that the flow divider cone 30 can be integrally formed with the plate 20, or it can be configured as a separate structure. In this embodiment, the flow divider cone 30 and the plate 20 are separate structures. Figure 7As shown, the plate 20 is provided with a clearance hole 203. In this embodiment, the clearance hole 203 is opened in the middle of the plate 20, and the flow divider cone 30 is disposed in the clearance hole 203, with the small-diameter end of the flow divider cone 30 located in the expansion cavity 103. The flow divider cone 30 is disposed in the clearance hole 203 of the plate 20, and the flow divider cone 30 is welded and fixed to the plate 20. This arrangement helps to adjust the insertion depth of the flow divider cone 30, ensuring the distance between the flow divider cone 30 and the inflow hole 111, which helps to improve the applicability of the distributor 100 and adjust the flow divider effect. On the other hand, the flow divider cone 30 can be set as a cone, triangular pyramid, square pyramid, pentagonal pyramid, etc., to adapt to the number of flow divider holes 201, ensuring the flow divider effect. At the same time, it helps to improve the diversity of the flow divider cone 30, thereby improving the applicability of the distributor 100.

[0100] like Figure 7 and Figure 10 As shown, the flow divider cone 30 includes a cone 31, an extension 32, and a second flange 33. The cone 31, extension 32, and second flange 33 are sequentially connected in the direction from the inlet hole 111 toward the plate 20. The extension 32 is adapted to fit the inner wall of the clearance hole 203. Optionally, the cone 31 is disposed inside the expansion cavity 103, and the second flange 33 is fitted and connected to the side of the plate 20 opposite to the expansion cavity 103. By providing the extension 32, which can cooperate with the clearance hole 203, a sealed connection between the plate 20 and the flow divider cone 30 is achieved. Meanwhile, the second flange 33 helps to further improve the sealing effect between the plate 20 and the diverter cone 30; on the other hand, it can also improve the assembly efficiency of the plate 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 20, which helps to further improve the connection effect between the diverter cone 30 and the plate 20.

[0101] It should be noted that when the cone 31 of the flow divider cone 30 is set in the mounting cavity 104, the second flange 33 is attached to the side of the plate 20 facing the expansion cavity 103. At this time, the welding position between the flow divider cone 30 and the plate 20 is the connection between the cone 31 and the plate 20. This setting helps to reduce the impact of welding on the flow of refrigerant, so as to ensure the effect of the flow divider cone 30.

[0102] Furthermore, in this embodiment, the internal hollowing-out design of the diversion cone 30 helps to reduce the weight of the diversion cone 30, thereby ensuring the diversion cone 30's guiding effect while reducing the manufacturing cost of the distributor 100.

[0103] In addition, such as Figures 4 to 7As shown, in this embodiment, when there is only one connecting part 41, the connecting part 41 has an assembly hole 420 in the middle for the connecting part 41 to be adapted to the second flange 33. At this time, the connecting part 41 has a ring-shaped structure, and the inner ring of the connecting part 41 is fitted to the second flange 33 for welding and fixing. At the same time, the outer ring of the connecting part 41 is fitted to the inner wall of the mounting cavity 104 for connecting and fixing the connecting member 40 to the housing 10.

[0104] Furthermore, the first connecting pipe 200 is a rigid component. Specifically, by defining the first connecting pipe 200 as a rigid component, it is helpful to realize the welding of the first connecting pipe 200 to the plate 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 respectively, it is helpful to realize the automated welding of the first connecting pipes 200 to the first heat exchanger, thereby helping to prevent the problem of springback after the first connecting pipes 200 are connected.

[0105] It should be understood that in this embodiment, the first connecting pipe 200 is a rigid component. One end of the first connecting pipe 200 is connected to the insertion part, and the other end of the first connecting pipe 200 is provided with a first adapter 60. As shown in the figure, multiple first connecting pipes 200 extend along different preset paths. By making the pipe body a rigid component, it is easier for the first connecting pipe 200 to connect with the insertion part, facilitating subsequent welding and fixing, and effectively preventing the first connecting pipe 200 from springing back after being inserted into the heat exchanger. The overall structure of the first connecting pipe 200 is simple and easy to process and form, which helps to reduce processing costs and reduce the external size of the distributor 100. It also requires less structural space, which helps to save design space and achieve lightweight design.

[0106] In this embodiment, the first adapter 60 is inserted into the first connecting pipe 200, and the first adapter 60 is adapted to the connection port of the first heat exchanger 2000. The connection method includes, but is not limited to, screw connection, snap connection, snap-fit ​​connection, riveting, bonding, welding, etc. Optionally, the first adapter 60 is fixed to the connection port by welding.

[0107] It should be noted that the material of the first adapter 60 is the same as that of the connector, which helps to improve the connection effect between the first connector 40 and the connector, thereby ensuring the stability of the connection. The material of the first adapter 60 and the first connecting pipe 200 may be the same or different, and no further restrictions are imposed here. Optionally, the first adapter 60 may be made of brass, stainless steel, etc.

[0108] It should be further understood that the distributor 100 has a first insertion portion 11, which defines an inlet orifice 111. The diversion assembly also includes a second connecting tube 300, which is sleeved on the outside of the first insertion portion 11. By providing the first insertion portion 11 on the distributor 100, enabling insertion and connection with the second connecting tube 300, the assembly difficulty of the diversion assembly is reduced, and the assembly efficiency of the diversion assembly is improved.

[0109] As shown in Figures 1, 2, and 3, the bottom of the dispenser 100 protrudes outward and forms a first insert portion 11. The interior of the first insert portion 11 defines an inlet hole 111. Simultaneously, a second connecting pipe 300 is sleeved on the outside of the first insert portion 11. In this embodiment, the second connecting pipe 300 includes an inlet pipe 301, the interior of which defines a cavity. This cavity includes an injection cavity 101 and a connecting cavity (not shown in the figures). The injection cavity 101 is used for the inflow of refrigerant, and the connecting cavity is sleeved on the outside of the first insert portion 11 so that the refrigerant flowing through the injection cavity 101 enters the expansion cavity 103 through the inlet.

[0110] In this embodiment, the inner diameter of the injection cavity 101 is larger than the inner diameter of the connecting cavity. A transition cavity (not shown in the figure) is also provided between the injection cavity 101 and the connecting cavity to ensure that the refrigerant can enter the inlet hole 111. At this time, along the refrigerant flow path, the inlet pipe 301 and the housing 10 cooperate to form the injection cavity 101, the flow stabilizing cavity 102 (inlet hole 111), and the expansion cavity 103, which are connected in sequence. By limiting the inner diameters of the injection cavity 101, the flow stabilizing cavity 102, and the expansion cavity 103, the inlet pipe 301 and the housing 10 cooperate to form a Venturi tube structure, thereby increasing the flow velocity by reducing the flow area and creating a low-pressure area at the throat. The change in refrigerant flow velocity helps to further improve the refrigerant mixing effect and increase the refrigerant flow velocity to each diversion hole 201, thus ensuring the diversion effect of the diversion assembly.

[0111] It should be noted that, in addition to fitting the inlet pipe 301 onto the outside of the first insert portion 11, the end of the inlet pipe 301 near the expansion cavity 103 can also be inserted into the inflow hole 111. Of course, besides the insert method, other methods such as screw connection, flange connection, or welding can also be used. Optionally, multiple welded parts can be provided at the connection between the inlet pipe 301 and the first insert portion 11 to further improve the connection effect between the inlet pipe 301 and the first insert 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 diversion assembly and improve the assembly efficiency of the diversion assembly.

[0113] Furthermore, the second connecting pipe 300 also includes an inlet pipe 301 and a second adapter 70. The inlet pipe 301 is sleeved on the first insert portion 11 and has an inlet cavity 101, the inner diameter of which is larger than the inner diameter of the inlet hole 111. The second adapter 70 is inserted at the end of the inlet pipe 301 opposite to the inlet hole 111.

[0114] Specifically, by setting the inlet pipe 301, the distribution assembly 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 it enters the distributor 100 from the second connecting pipe 300, and improving the refrigerant distribution and mixing effect in conjunction with the distribution cone 30. Simultaneously, the setting of the second adapter 70 allows the inlet pipe 301 to communicate with other connection structures, and by changing the material of the second adapter 70, the inlet pipe 301 can be inserted and welded to other connection structures, thus improving the applicability of the inlet pipe 301 and consequently the applicability of the distribution assembly.

[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 is made of the same material as the inlet pipe 301. By setting 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 inlet pipe 301 is designed to cooperate with the housing 10 to form a Venturi tube structure, and the second adapter 70 further improves the applicability of the distribution assembly, resulting in a better connection effect between the inlet pipe 301 and the connecting pipe, ensuring the stability of refrigerant transmission, and extending the service life of the distribution assembly.

[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 can be screwed onto the outer circumferential surface of the inlet pipe 301, or the connecting pipe and the inlet pipe 301 can be 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 utility model also provides a heating, ventilation and air conditioning (HVAC) device 1, which includes a first heat exchanger 2000, a second heat exchanger 3000, and a distribution assembly 1000, wherein the distribution assembly 1000 is the aforementioned distribution assembly 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.
