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] In liquid distribution systems, the design and installation of the dispenser significantly impacts system performance and reliability. Currently available dispensers and the first connecting pipe present significant challenges during installation, particularly during the welding phase. Due to the high precision required for alignment, this often leads to post-weld misalignment. This not only increases installation time and cost but can also impact the dispenser's functionality and service life. Furthermore, misalignment can lead to uneven liquid flow, compromising the overall system's efficiency.

[0003] Existing technologies often lack effective auxiliary tools to ensure precise positioning between the liquid dispenser and the first connecting pipe, which makes the operator face more challenges during the installation process. Therefore, a new auxiliary tooling design is urgently needed to simplify the installation process and improve the alignment accuracy of welding. Utility Model Content

[0042] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0043] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an" and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", "contain" and "have" are inclusive and therefore specify the presence of stated features, steps, operations, elements and / or parts, but do not exclude the presence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof.

[0044] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0045] For ease of description, spatially relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," and the like.

Thus, the example term "below" can encompass both above and below orientations.

[0046] like Figure 9 and Figure 10 As shown, the distributor 100 of this embodiment includes a shell 10, a plate body 20 and a diverter cone 30, wherein the shell 10 is provided with an inflow hole 111, the plate body 20 closes the shell 10 to form an expansion cavity 103, and at least three diverter holes 201 are spaced apart on the plate body 20. The diverter cone 30 is arranged inside the expansion cavity 103 and is connected to the plate body 20. The top end of the diverter cone 30 is arranged opposite to the inflow hole 111, and the fluid is guided from the inflow hole 111 to the diverter hole 201 by the diverter cone 30.

[0047] Specifically, the plate body 20 includes a first plate body 21 and a second plate body 22 connected to each other, at least three diversion holes 201 are opened on the first plate body 21, and at least three insertion holes 202 are opened on the second plate body 22. The at least three diversion holes 201 are connected to the at least three insertion holes 202 in a one-to-one correspondence, and the diversion cone 30 and the first plate body 21 are an integrated structure.

[0048] Furthermore, the flow diversion assembly 1000 includes a distributor 100, a second connecting pipe 300, and a first connecting pipe 200. The second connecting pipe 300 includes an inlet pipe 301 and an inlet pipe 302 connected to each other. The second connecting pipe 300 is connected to the inflow hole 111 through the inlet pipe 301. Specifically, the housing 10 is provided with a first inserting portion 11 for accommodating the inlet pipe 301. The first connecting pipe 200 is connected to the diversion hole 201 and is inserted into the diversion hole 201 of the second plate 22. The flow diversion assembly 1000, with the distributor 100 as its core component, achieves uniform distribution of the fluid through its diversion cone 30, the first plate 21, and the diversion hole 201. The second connecting pipe 300 is connected to the inflow hole 111 of the distributor 100 and is responsible for introducing the fluid from the main system into the expansion chamber 103, while the first connecting pipe 200 is connected to the diversion hole 201 and is used to further transport the fluid from the diversion hole 201 to various downstream pipelines or terminal devices.

[0049] Furthermore, the incoming flow pipe 302 includes a second adapter, and the second adapter of the incoming flow pipe 302 is connected to the inlet pipe 301 .

[0050] like Figures 1 to 8 As shown, according to the embodiment of the present utility model, a diversion component 1000 is proposed, which includes a distributor 100, a limiting member 400 and a plurality of first connecting tubes 200, wherein the distributor 100 is provided with a plurality of diversion holes 201, and the limiting member 400 is provided with a plurality of limiting holes, the plurality of limiting holes correspond one to one with the plurality of diversion holes 201 and are coaxially arranged, each first connecting tube 200 passes through a limiting hole and is connected to a diversion hole 201, and the outer diameter of the first connecting tube 200 is equal to the inner diameter of the limiting hole.

[0051] According to the flow diversion assembly 1000 of this embodiment, the limiting hole on the limiting member 400 is coaxially arranged with the diversion hole 201, and the outer diameter of the first connecting tube 200 is equal to the inner diameter of the limiting hole. This ensures that the first connecting tube 200 can be stably aligned with the diversion hole 201 during installation, avoiding the problem of low welding precision caused by positional offset. At the same time, the mechanical positioning function of the limiting member 400 ensures that the first connecting tube 200 can be accurately fixed in the appropriate position before welding, reducing displacement and vibration of the first connecting tube 200 during welding and further improving welding quality.

[0052] like Figures 1 to 4As shown, in the first embodiment, the limiting member 400 includes a first limiting plate 401, and a plurality of limiting holes are provided on the first limiting plate 401. Along the direction from the first limiting plate 401 to the distributor 100, there is a first distance between the first limiting plate 401 and the distributor 100, and the first distance is greater than zero. The plurality of limiting holes on the first limiting plate 401, since the inner diameter of the limiting holes is equal to the outer diameter of the first connecting tube 200, a certain friction force is generated between the two. This friction force plays a structural role in preventing the first limiting plate 401 from slipping. Therefore, when the first connecting tube 200 passes through the limiting hole, due to the precise matching of the hole diameter and the tube diameter, the first connecting tube 200 can be firmly fixed in the first limiting hole 4011 without any sliding or displacement. At this time, the first connecting tube 200 is kept stable by the tight fit of the first limiting plate 401.

[0053] It is understood that the first distance provides the first connecting pipe 200 with a sufficient fixed length, which means that the straight section of the first connecting pipe 200 can be stably inserted into the limiting hole and the diverter hole 201 and accurately positioned by the limiting hole. In this way, the first connecting pipe 200 will not shake or shift before welding, greatly improving the installation accuracy of the pipeline. The longer the fixed length, the greater the stability of the first connecting pipe 200, which allows the first connecting pipe 200 to remain relatively stationary during the welding process, reducing welding defects caused by movement during the welding process. Through the first distance between the first limiting plate 401 and the distributor 100, the first connecting pipe 200 can be maintained in a straight line and can be precisely aligned with the diverter hole 201. This design ensures that the positions of the first connecting pipe 200 and the diverter hole 201 are highly consistent during welding, eliminating welding deviations caused by inaccurate alignment during traditional welding processes. Before welding, the first connecting pipe 200 has been firmly and accurately inserted into the limiting hole and the diverter hole 201. This structural design reduces the problem of inaccurate welding alignment and thus improves the welding effect.

[0054] Specifically, the first distance is greater than 30 mm. When the first distance is greater than 30 mm, the first connecting tube 200 has a sufficient straight section length between the first limiting plate 401 and the distributor 100, which not only helps to firmly fix the first connecting tube 200 in the appropriate position before welding, but also provides sufficient support to ensure that the first connecting tube 200 will not easily shake or shift during the welding process.

[0055] like Figures 5 to 8As shown, in the second embodiment, the limiting member 400 includes a first limiting plate 401 and a second limiting plate 402. The first limiting plate 401 and the distributor 100 are located on opposite sides of the second limiting plate 402, respectively. The limiting holes include a first limiting hole 4011 and a second limiting hole 4021. The first limiting plate 401 is provided with a plurality of first limiting holes 4011, and the second limiting plate 402 is provided with a plurality of second limiting holes 4021. The plurality of first limiting holes 4011 and the plurality of second limiting holes 4021 are coaxially arranged in a one-to-one correspondence. Correspondingly, the first limiting holes 4011 and the second limiting holes 4021 constitute the limiting holes. Compared to the first embodiment, the dual limiting design between the first limiting plate 401 and the second limiting plate 402 supports the first connecting pipe 200 through the two coaxial first limiting holes 4011 and the second limiting holes 4021, significantly enhancing the stability of the first connecting pipe 200. Compared with a single limiting plate, the double limiting plate can effectively prevent the first connecting pipe 200 from any tilting or shaking during the installation and welding process, ensuring that it is in the correct position before welding.

[0056] Specifically, along the direction from the first limiting plate 401 to the second limiting plate 402, there is a second distance between the first limiting plate 401 and the second limiting plate 402, which is greater than or equal to 30 mm. This second distance of greater than or equal to 30 mm ensures that the first connecting tube 200 has a sufficient straight segment length fixed between the first limiting plate 401 and the second limiting plate 402. The larger support length provides a more stable fixation, preventing the first connecting tube 200 from tilting, shaking, or shifting during welding and installation, and also helps improve alignment accuracy during welding.

[0057] Specifically, along the direction from the second limiting plate 402 to the distributor 100, there is a third distance between the second limiting plate 402 and the distributor 100, and the third distance is greater than or equal to 5 mm. The third distance is greater than or equal to 5 mm, ensuring that there is sufficient space between the second limiting plate 402 and the distributor 100 for the insertion and welding of the first connecting tube 200. The 5 mm distance allows the operator to easily access the welding point between the first connecting tube 200 and the diverter hole 201, avoiding welding inconvenience or errors caused by insufficient space during operation. In addition, the appropriate third distance provides room for subsequent pipeline adjustment and inspection, improving the controllability and convenience of installation.

[0058] It is understood that the stopper 400 further includes a support structure 403, which connects the first stopper plate 401 and the second stopper plate 402. The support structure 403 connects the first stopper plate 401 and the second stopper plate 402, forming a stable stopper 400. The support structure 403 effectively prevents relative displacement between the two stopper plates during welding or installation, ensuring that the first connecting pipe 200 remains in the correct position.

[0059] Specifically, the first limiting plate 401 and the second limiting plate 402 have the same structure and are both circular plates, and the support structure 403 is a support rod, which is coaxially arranged with the first limiting plate 401 and the second limiting plate 402 respectively. The first limiting plate 401 and the second limiting plate 402 are both circular plates with the same structure, which ensures the symmetry of the entire limiting member 400. The circular plate design not only helps to evenly distribute the limiting holes, but also reduces stress concentration points, thereby improving the stability and durability of the overall structure. The coaxially arranged support rods serve as the main axis structure, further enhancing the stability and rigidity between the limiting plates. The support rods provide balanced mechanical support to ensure that the limiting plates remain coaxially aligned during use and avoid any offset. At the same time, the circular plate structure and the coaxial support rod design make the limiting member 400 easier to process and assemble during the manufacturing process. The circular structure makes the arrangement of the limiting holes more uniform, reduces positioning errors, and the coaxial design between the limiting plates ensures the consistency of each limiting hole. Since the support rod and the limit plate are coaxially arranged, the two limit plates can be ensured to always maintain a constant relative position during assembly, thereby improving the positioning accuracy of the first connecting pipe 200 during installation and reducing the need for manual adjustment.

[0060] Furthermore, the support rod has a hollow structure. This significantly reduces the overall weight of the stopper 400 while maintaining its basic support capacity. This is particularly important for large-scale HVAC equipment 1 or the diversion assembly 1000 in complex systems, as reducing weight helps alleviate the burden on the system. This weight reduction also reduces transportation and installation costs, facilitates operation and maintenance, and increases the flexibility of the assembly.

[0061] Specifically, the support structure 403 can also be a hollow support tube, the outer edge of the upper end of the support tube is connected to the circumferential outer edge of the first limiting plate 401, the outer edge of the lower end of the support tube is connected to the circumferential outer edge of the second limiting plate 402, and the first connecting tube 200 located between the first limiting plate 401 and the second limiting plate 402 is accommodated inside the support tube. The support tube, as an integral hollow structure, is connected to the circumferential outer edges of the first limiting plate 401 and the second limiting plate 402 to form a closed structural unit. This not only improves the rigidity of the limiting member 400, but also enhances the stability of the entire diversion assembly 1000. This design can effectively prevent relative displacement or deformation between the two limiting plates, ensure the alignment accuracy and fixing stability of the first connecting tube 200 during use, and improve the reliability of welding and installation.

[0062] In some embodiments, the limiting holes are spaced at equal intervals along the circumference of the limiting member 400. The equal spacing of the limiting holes ensures that the first connecting tubes 200 are symmetrically distributed around the circumference of the limiting member 400. This effectively prevents the first connecting tubes 200 from shifting during welding or assembly, ensuring that each first connecting tube 200 is precisely aligned with the corresponding diverter hole 201. This symmetrical distribution ensures that each first connecting tube 200 is evenly stressed, reducing mechanical stress imbalances caused by uneven distribution and improving the overall alignment accuracy and stability of the diverter assembly 1000.

[0063] like Figure 11 As shown, this embodiment also provides a HVAC device 1, which includes the above-mentioned diversion component 1000, a first heat exchanger 2000, a second heat exchanger 3000, a compressor 4000, a refrigeration throttle valve 5000, and a four-way valve 6000. After the first heat exchanger 2000 receives the refrigerant from the diversion component 1000, the first heat exchanger 2000 performs a heat absorption process, causing the refrigerant to evaporate and absorb heat from the environment. The low-pressure gaseous refrigerant received by the compressor 4000 from the first heat exchanger 2000 is pressurized by the compressor 4000 and converted into a high-pressure gaseous refrigerant, which is then transported to the four-way valve 6000 through a pipeline. The four-way valve 6000 is used to adjust the flow direction of the refrigerant and switch between cooling and heating modes. In cooling mode, the refrigerant passes through the second heat exchanger 3000, the refrigeration throttle valve 5000, the flow diverter assembly 1000, and the first heat exchanger 2000 before returning to the compressor 4000. In heating mode, the refrigerant returns from the first heat exchanger 2000 to the compressor 4000. The design of the entire HVAC system 1 achieves higher fluid control precision through the flow diverter assembly 1000, enhancing system stability. The precise coordination and flow control of each component ensure stable operation under different operating conditions, reducing failures and maintenance requirements.

[0064] 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.
