At least one communication channel is formed in the valve island body. At least two interfaces of the communication channel are formed on the surface of the valve island body. The support is connected with the valve island body to support the valve island body. The weight of the valve island body is W, and 50g≤W≤2334g is met. The valve island body is directly used to replace the original multi-section welded pipeline. The communication channel is connected through a preset integrated flow channel in the valve island body. The pipeline does not need to be additionally spliced, and a redundant straight section and a bending radius for meeting the bending process requirement do not need to be arranged, so that the fluid transmission path is simplified. Since the material consumption and the welded connector consumption of the original multi-section pipeline are replaced by the integrated communication channel, and the weight of the valve island body is controlled in a reasonable range, compared with a traditional transmission system composed of a multi-section pipeline and a welded connector, the overall weight is significantly reduced.

Description

Technical Field

[0001] This application relates to the field of household appliances, and in particular to a valve island module, valve island assembly, and air conditioner. Background Technology

[0002] In related technologies, air conditioning systems include multiple components that are connected to each other through pipes. However, current pipe connections require welding multiple pipe sections together, and pipe bends must have straight sections and bending radii. Both straight sections and bending radii have a minimum size, which leads to complex pipework, resulting in heavy pipes, high costs, and inconvenient installation. Therefore, how to reduce the weight of the pipes has become the technical problem to be solved in this application. Utility Model Content

[0003] This application aims to at least address one of the technical problems existing in the prior art. To this end, one objective of this application is to provide a valve island module that can reduce the weight of the piping.

[0007] According to the valve island module of this application embodiment, by setting a valve island body, at least one connecting channel integrated inside the valve island body can directly replace the original multi-section welded pipeline. The connecting channel achieves fluid conduction through an integrated flow channel preset in the valve island body, eliminating the need for additional pipeline splicing and redundant straight sections and bending radii to meet bending process requirements, thereby simplifying the fluid transmission path.

[0022] The following is a brief description of the valve island assembly according to an embodiment of this application. The valve island assembly according to an embodiment of this application includes valve island modules of any of the above embodiments. The valve island modules are constructed in multiple ways. Since the valve island assembly according to this embodiment is provided with multiple valve island modules of any of the above embodiments, the valve island assembly has replaced multiple sections of welded pipes through a single valve island module and a connecting channel. When multiple valve island modules are composed of valve island modules, the valve island assembly does not need to set redundant straight sections, bending structures and welded parts for each channel. The number of fluid transmission channels can be expanded simply by combining the interfaces of the valve island modules. This makes the overall weight of the assembly significantly reduced compared to traditional multi-channel pipeline systems, further enhancing the technical effect of weight reduction. At the same time, the valve island assembly composed of multiple valve island modules can flexibly increase or decrease the number of valve island modules according to actual fluid transmission needs, which greatly reduces the workload of re-cutting and welding pipes due to functional adjustments in traditional pipeline systems. The installation efficiency is significantly improved, and the cost and construction period loss caused by pipeline modification are reduced.

[0025] The air conditioner according to the embodiments of this application includes a valve island module or valve island assembly of any of the above embodiments. Since the air conditioner according to this embodiment is equipped with a valve island module or valve island assembly of any of the above embodiments, and the air conditioner has a requirement for multi-channel fluid transmission, the connecting channel of the valve island module can replace the original multi-section welded pipes of the air conditioner. The valve island assembly can achieve integrated transmission of multi-channel fluids through the combination of multiple valve island modules, which can significantly reduce the total length of the internal pipes of the air conditioner, the number of welding points, and the redundant structure caused by bending requirements, directly reducing the overall weight of the air conditioner, while also reducing the amount of pipe material used and controlling... Production costs are reduced; secondly, the interface of the valve island module / assembly simplifies the docking process with components such as the compressor, heat exchanger, and solenoid valve inside the air conditioner, eliminating the need for segmented pipe cutting, bending, and welding, thus shortening the assembly period. Furthermore, the integrated structure of the valve island module / assembly is more compact, effectively utilizing the limited internal space of the air conditioner and improving the regularity of the internal structure. Simultaneously, the connection channels of the valve island module / assembly have no welding sealing risks, reducing the risk of air conditioner malfunctions such as decreased cooling / heating efficiency and refrigerant leakage due to pipe welding leaks, ensuring long-term stable operation of the air conditioner.

[0026] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0029] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0030] The following is for reference. Figures 1-6 This application describes a valve island module 100 according to an embodiment of the present application.

[0031] According to an embodiment of this application, the valve island module 100 includes: a valve island body 1 and a support member. The valve island body 1 has at least one communicating channel 11 formed inside, and at least two interfaces of the communicating channel 11 are formed on the surface of the valve island body 1. The support member is connected to the valve island body 1 to support the valve island body. The weight of the valve island body 1 is W, and satisfies: 50g≤W≤2334g.

[0032] In related technologies, air conditioning systems include multiple components that are connected to each other through pipes. However, current pipe connections require welding multiple pipe sections together, and pipe bends must have straight sections and bending radii. Both straight sections and bending radii have a minimum size, which leads to complex pipework, heavy pipework, high cost, and inconvenient installation.

[0033] Understandably, in response to the core problem of the need for welding connections between multiple pipe sections in related technologies, and the complexity of pipe structures due to process requirements for straight sections and minimum bending radii, at least one connecting channel 11 integrated inside the valve island body 1 provides a structural replacement for traditional multi-section welded pipes. The fluid conduction function is accomplished by the integrally formed connecting channel 11 inside the valve island body 1, avoiding the need for welding and splicing of multiple pipe sections, and also avoiding the need to reserve redundant straight sections and minimum bending radii to meet pipe bending processes. This eliminates the structural redundancy caused by splicing and process limitations in traditional pipe systems, simplifying the pipe structure. At the same time, the valve island body 1 needs to achieve load-bearing function through support components to ensure the stability of the connection with the pipe. In this supported state, the vibration generated by the compressor operation will be transmitted to the valve island along the pipeline. If the valve island body 1 is too light, its own inertia is not enough to offset the vibration impact, which will cause excessive vibration at the connection between the valve island body 1 and the pipeline, and at the same time cause high-frequency vibration of the valve island body 1. If the valve island body 1 is too heavy, although it can enhance the vibration resistance, it will increase the load on the support components and the overall weight of the system, which does not meet the requirements of lightweighting.

[0034] Therefore, based on the above-mentioned vibration transmission characteristics and support stability requirements, this application limits the weight of the valve island body 1 to a specific threshold range. This range can ensure that the valve island body 1, under the support of the support components, can form sufficient inertia through its own weight to suppress the vibration of the connection parts and the body caused by the vibration transmission of the compressor, thereby avoiding reliability problems such as sealing failure and loosening of internal components of the valve island body 1 caused by vibration. It can also avoid the increase in system burden caused by excessive weight, thereby meeting the reliability requirements of the support components while taking into account the goal of lightweight system design.

[0035] Furthermore, the weight composition of a conventional piping system includes the weight of pipes in multiple sections, the weight of welded connections, and the additional weight of pipes in redundant straight sections and bends. The aforementioned weights are replaced by the valve island body 1, and the weight of the valve island body 1 is in the range of 50g to 2334g, which is lower than that of a conventional transmission system composed of multiple pipes and welded connections under the same fluid transmission conditions.

[0036] Understandably, in fluid transmission scenarios involving small valve island bodies 1 with low flow rates and short distances, traditional solutions require splicing multiple pipe sections to meet the requirements. However, because each pipe section needs to reserve a minimum straight section and bending radius, its total weight will still exceed 50g. Valve island body 1, on the other hand, achieves the same conduction function with a weight of 50g while reducing weight, and has sufficient inertia to suppress vibration of the connection parts and body caused by compressor vibration transmission. The weight limit of 2334g is suitable for the fluid transmission system requirements of medium and large valve island bodies 1. For traditional systems that require splicing multiple long pipe sections and include multiple bending nodes, their total weight often exceeds 2334g significantly due to the increase in the amount of pipe material and the number of welded parts. Valve island body 1, through the integration of multiple internal connecting channels 11, can replace multiple sets of traditional pipes. When meeting the requirements of larger flow rates or multi-path transmission, the weight is still controlled within 2334g, avoiding the problems of excessive weight, increased cost, and installation difficulties caused by the increase in the number of pipes in traditional systems.

[0037] When W is less than 50g, the size of the valve island body 1 needs to be significantly reduced due to weight constraints. Integrating at least one connecting channel 11 and opening at least two interfaces within this reduced size will result in the inner diameter of the connecting channel 11 and the structural strength of the body being insufficient to meet basic fluid transmission requirements. This could lead to the connecting channel 11 having an excessively small inner diameter, failing to achieve effective fluid flow, or the valve island body 1 having an excessively thin wall thickness, making it prone to structural damage under installation, docking, or fluid pressure. Consequently, it cannot replace traditional multi-section pipelines to complete the fluid transmission function, and the core goal of weight reduction cannot be achieved. Furthermore, when W is less than 50g, the inertia generated by the mass of the valve island body 1 itself is insufficient to offset the vibration energy transmitted by the compressor through the pipeline. When the compressor vibration is transmitted along the support to the connection point of the valve island body 1 under the support condition, the valve island body 1, due to its insufficient inertia, cannot form effective vibration damping and will generate high-frequency, large-amplitude vibrations synchronously with the vibration energy. Excessive vibration will directly cause repeated stress impacts at the connection of the valve island body 1, which can easily cause the interface sealing structure to fail and refrigerant leakage problems. At the same time, the valve core, electromagnetic coil and other precision components inside the valve island body 1 will also shift in position or loosen the connection between components due to continuous vibration, which will damage the normal on and off control function of the valve island and ultimately lead to a decrease in the reliability of the air conditioning system, making it unable to meet the basic reliability requirements under the premise of pipe support.

[0038] When W is greater than 2334g, the weight of the valve island body 1, which exceeds 2334g, will be close to or even exceed the total weight of some medium and large traditional pipeline systems, and will not be able to demonstrate the weight advantage over traditional pipelines. At the same time, the excessive weight of the valve island body 1 will increase the difficulty of handling during installation, and will require the design of a more stable fixing structure to support its weight, which will lead to a decrease in installation convenience.

[0039] It should be noted that traditional pipeline systems require welding, positioning, and bending operations section by section, which is cumbersome and prone to sealing failure due to welding quality. In contrast, the valve island module 100 connects to external components through the interface on the surface of the valve island body 1, simplifying the installation process. At the same time, the integrated connecting channel 11 avoids the sealing risks caused by too many welding points.

[0040] In short, by setting up the valve island body 1, and integrating at least one connecting channel 11 within the valve island body 1, the original multi-section welded pipeline can be directly replaced. The connecting channel 11 achieves fluid conduction through a pre-set integrated flow channel within the valve island body 1, eliminating the need for additional pipeline splicing and redundant straight sections and bending radii to meet bending process requirements, thereby simplifying the fluid transmission path. Since the material consumption and welding connection consumption of the original multi-section pipeline are replaced by the integrated connecting channel 11, the overall weight is significantly reduced compared to the traditional transmission system composed of multi-section pipelines and welded components. Moreover, there is no need to perform segmented welding, positioning, and bending operations on the multi-section pipeline; it only requires docking with external components through at least two interfaces on the surface of the valve island body 1, reducing installation procedures and operational difficulty, and avoiding the sealing reliability risks caused by pipeline welding.

[0041] In some embodiments of this application, the support is constructed as a support pipe 6, the valve island body 1 is connected to at least one support pipe 6, and the support pipe 6 is adapted to communicate with the pipeline system. The diameter of the support pipe 6 is between 16mm and 19mm, including 16mm or 19mm. Of course, other diameter support pipes can also be used to support or lift the valve island module 100 while ensuring reliability.

[0042] According to some embodiments of the present application, the valve island module 100 has a valve island body 1 constructed of aluminum and its weight satisfies: 50g≤W≤975g.

[0043] Understandably, the valve island body 1 is constructed of aluminum, which inherently possesses low density. Combined with its integrated connecting channel 11, it can replace traditional multi-section welded pipes, eliminating the redundant weight generated by splicing and bending processes in traditional pipes. Furthermore, the low density of aluminum further amplifies the weight optimization effect, allowing the weight to be controlled within a reasonable range while ensuring fluid conduction. If the valve island body 1 weighs less than 50g, even with the low density of aluminum, integrating at least one connecting channel 11 and opening at least two interfaces on such a lightweight body would result in insufficient structural strength, making it impossible to replace the function of traditional pipes. When the weight of the valve island body 1 exceeds 975g, although the density of aluminum is lower than that of traditional pipes, the weight of the aluminum valve island body 1 that exceeds the standard will be close to or even exceed that of the traditional pipeline system under the same fluid transmission conditions, and the weight advantage cannot be reflected. The range of 50g≤W≤975g not only makes use of the characteristics of aluminum to ensure that the body has sufficient strength and normal channel function while being lightweight, but also avoids losing the advantage due to excessive weight. At the same time, the ease of processing aluminum allows for more precise forming of the connecting channel 11, ensuring stable fluid transmission.

[0044] According to some embodiments of the present application, the valve island module 100 has a valve island body 1 constructed of stainless steel and a weight that satisfies: 765g≤W≤2334g.

[0045] Understandably, stainless steel possesses high strength and high corrosion resistance, making it suitable for scenarios requiring stable fluid transmission, pressure resistance, and resistance to media corrosion. Similarly, the internally integrated connecting channel 11 can replace traditional multi-section welded pipes, eliminating structural redundancy caused by splicing and bending processes in traditional pipes. Stainless steel has a higher density than aluminum, and this weight range ensures that the main body has sufficient wall thickness to maintain high strength and meet structural stability requirements under fluid pressure. At the same time, the integrated connecting channel 11 avoids redundant weight in traditional pipes, achieving weight optimization of traditional multi-section stainless steel pipes and achieving the core goal of reducing overall weight. Furthermore, the corrosion resistance of stainless steel can prevent fluid media from eroding the channel, extending the module's service life and ensuring long-term reliable operation.

[0046] If the valve island body 1 weighs less than 765g, due to the high density of stainless steel, controlling the weight within this range would require a significant reduction in the body wall thickness and volume. This would result in an excessively small inner diameter of the connecting channel 11, failing to meet normal flow requirements. Simultaneously, an excessively thin wall thickness would lead to insufficient structural strength, making the body prone to deformation or even breakage during installation, connection, or under fluid pressure. This would prevent the realization of basic fluid transmission functions and would also fail to demonstrate the strength advantages of stainless steel, thus losing its value as a replacement for traditional pipelines. If the valve island body 1 weighs more than 2334g, although it may improve structural strength and channel capacity, an excessively heavy valve island body 1 would increase the difficulty of installation and handling, requiring additional fixing structures and reducing installation convenience. The range of g≤W≤g can effectively replace traditional multi-section pipelines while ensuring that the valve island module 100 has sufficient strength, meets the requirements for fluid transmission functions and corrosion resistance, achieving the technical effects of weight reduction and simplified installation.

[0047] According to some embodiments of the present application, the valve island module 100 has a communication channel 11 formed inside the valve island body 1, and a first interface and a second interface connected to the communication channel 11 are formed on the surface of the valve island body 1; and satisfies: 50g≤W≤150g.

[0048] Understandably, for a small valve island module 100 with a connecting channel 11 inside the valve island body 1, the single connecting channel 11 achieves the connection between the first interface and the second interface through the integrated structure inside the valve island body 1. This can replace the multi-section welded pipes used for fluid transmission between two points in traditional scenarios. There is no need to reserve redundant straight sections and bending radii to meet the bending process, nor is there a need for additional welded connectors. The weight range of 50g to 150g makes the weight of the valve island body 1 significantly lower. At the same time, external docking can be completed through only two interfaces, which greatly simplifies the installation process and improves the ease of assembly. Meanwhile, the weight range of 50g to 150g ensures that the valve island body 1 has sufficient wall thickness to support the forming of the connecting channel 11, avoiding insufficient structural strength of the body due to flow channel processing, while maintaining the miniaturization characteristics, making it suitable for scenarios with compact installation space requirements. Furthermore, the lightweight design further reduces the difficulty of positioning and fixing during installation, indirectly improving the overall assembly efficiency of the system.

[0049] According to some embodiments of this application, the valve island module 100 further includes: a valve assembly 2, which is disposed on the valve island body 1 and at least a portion of the valve assembly 2 is housed in the communication channel 11 and used to control the conduction state of the communication channel 11; or, the valve assembly 2 is connected to the communication channel 11 through a pipeline and used to control the conduction state of the communication channel 11.

[0050] At least a portion of the valve assembly 2 is housed within the connecting channel 11, or is connected to the connecting channel 11 via a pipeline. When at least a portion of the valve assembly 2 is housed within the connecting channel 11, the connection between the valve assembly 2 and the connecting channel 11 does not require additional transition joints or short pipes. This reduces the number of weld points generated by connecting multiple pipe sections and pipe connections in traditional piping systems. Due to the reduction in the number of weld points, it is not necessary to weld each pipe section and test the sealing performance point by point, reducing the dependence on the precision of the assembly process, thereby improving production efficiency and simplifying the assembly process. It also reduces leakage risk points and avoids sealing problems caused by process deviations, material fatigue, and other factors at welded parts in traditional piping systems. This enhances the long-term operational stability of the piping system and meets the requirements of the outdoor unit of the air conditioner for the sealing and reliability of the air conditioning piping. When the assembly 2 is connected to the connecting channel 11 via a pipeline, the installation position of the valve assembly 2 can be flexibly adjusted to adapt to different spatial layout requirements, without affecting the precise control of the conduction state of the connecting channel 11.

[0051] It should be noted that the valve assembly 2 controlling the conduction state of the connecting channel 11 means that the valve assembly 2 can control the opening and closing of the connecting channel 11, or the flow rate within the connecting channel 11, or further control the flow rate or opening and closing of the connecting channel 11 according to the linkage and synchronization of other devices.

[0052] like Figure 2 As shown, the valve island module 100 according to some embodiments of this application includes: a base 3; flow channel 31, wherein at least two flow channel 31 are configured and connected to the base 3, and a connecting channel 11 is formed in the flow channel 31, and at least two flow channel 31 are spaced apart on the base 3.

[0053] At least two flow channels 31 are connected to the base 3 and spaced apart on the base 3, so that there is no direct metal connection structure between the flow channels 31. The space between the flow channels 31 forms a physical gap 32. The thermal conductivity of the air in the gap 32 is much lower than that of the metal. When there is a temperature difference in the refrigerant in the refrigerant flow channels in different flow channels 31, the heat transfer path changes. The heat of the high-temperature flow channel 31 needs to be transferred to the base 3 first, and then transferred from the base 3 to the low-temperature flow channel 31, or through the gap 32 between the flow channels 31 for heat radiation and air convection. Since the connection between the base 3 and the flow channel 31 is only a local contact, the heat conduction area is greatly reduced compared to the large-area connection of the integral molded body. At the same time, the gap 32 formed by the interval of the flow channels 31 blocks the main heat conduction path of direct metal connection. The heat transfer rate through the air is much lower than that of direct metal conduction. In addition, each flow channel 31 independently carries the refrigerant flow channel, and there is no continuous metal structure between the flow channels. This avoids the efficient heat conduction channels formed by the body connection structure between the flow channels in related technologies, thereby reducing the amount of heat exchange between flow channels at different temperatures and reducing the adverse effects of heat transfer on the overall flow path energy efficiency.

[0054] According to some embodiments of the present application, each flow channel 31 of the valve island module 100 is constructed as a block and any two flow channel sections 31 are spaced apart from each other to form a gap 32 for airflow channels.

[0055] Since there is no direct metal connection between the block-shaped flow channels 31, the original continuous solid heat conduction path is blocked. Therefore, heat transfer between the flow channels 31 must be achieved through the air within the gaps 32. The thermal conductivity of air is much lower than that of metal materials, which significantly reduces the rate of heat conduction through the gaps 32.

[0056] Meanwhile, airflow can flow within the gap 32. The flowing airflow will carry away some of the heat from the surface of the flow channel 31, forming convective heat transfer. Convective heat transfer will not directly transfer heat to another flow channel 31, but will dissipate the heat to the environment, reducing the net heat exchange between the flow channel 31. The spacing of the block flow channel 31 reduces the relative surface area of ​​the two flow channel 31. Compared with the large area of ​​metal contact between the flow channels in the integral molding structure, the heat exchange area is significantly reduced. According to Fourier's law, the amount of heat transfer is positively correlated with the heat exchange area. Therefore, the reduction of the heat exchange area further reduces the total amount of heat transfer between the flow channel 31 and reduces the impact of heat transfer between the flow channel 31.

[0057] like Figure 3 As shown, the valve island module 100 according to some embodiments of this application includes: a first valve island body 4, in which a first connecting channel 41 is formed, a first refrigerant port 42 is formed, and a first spacer edge 43 is formed on one side of the first valve island body 4; a second valve island body 44, in which a second connecting channel 45 is formed, a second refrigerant port 46 is formed, and a second spacer edge 47 is formed on one side of the second valve island body 44, the second spacer edge 47 being spaced apart from the first spacer edge 43 to form an airflow channel 48.

[0058] In the valve island assembly 200 of this application embodiment, a first connecting channel 41 is formed in the first valve island body 4 and a first refrigerant port 42 is provided. A second connecting channel 45 is formed in the second valve island body 44 and a second refrigerant port 46 is provided. A first spacer edge 43 on one side of the first valve island body 4 and a second spacer edge 47 on one side of the second valve island body 44 are spaced apart, so that the first valve island body 4 and the second valve island body 44 are relatively independently arranged. At the same time, the spacer area of ​​the two spacer edges forms an airflow channel 48. The first refrigerant port 42 and the second refrigerant port 46 are adapted to communicate with the plate heat exchanger 7. When welding and assembling with the plate heat exchanger 7, the first refrigerant port 42 and the second refrigerant port 46 are first connected to the plate heat exchanger 7. One valve island body 1 (such as the first valve island body 4) is welded and positioned with the corresponding interface of the plate heat exchanger 7. At this time, the second valve island body 44 is not constrained by the structure of the first valve island body 4. It can make slight adjustments to its posture or position according to the actual positional relationship between its own interface and the remaining interfaces of the plate heat exchanger until the interface is completely aligned before welding is completed. Conversely, the second valve island body 44 can be welded first and then the first valve island body 4 can be adjusted. The phased adjustment and welding method eliminates the problem of interface tolerance that cannot be compensated due to welding deformation in traditional integrated valve islands. This significantly improves the assembly smoothness of the valve island component 200 and the plate heat exchanger in the air conditioning system, thereby improving the overall assembly efficiency.

[0059] Meanwhile, since a first partition edge 43 is formed on one side of the first valve island body 4 and a second partition edge 47 is formed on one side of the second valve island body 44, the first partition edge 43 and the second partition edge 47 are separated to form an airflow channel 48. Moreover, the first valve island body 4 has a first connecting channel 41 and the second valve island body 44 has a second connecting channel 45. There is a temperature difference between the refrigerant in the two channels. If the first valve island body 4 and the second valve island body 44 are in direct contact, heat will be transferred quickly through solid conduction, causing the refrigerant temperature in the channel to deviate from the design conditions and affecting the heat exchange efficiency of the air conditioning system. However, after the two bodies are separated by the airflow channel 48, the solid conduction path is cut off, and heat transfer needs to be carried out through the air in the gap 32. The thermal conductivity of air is much lower than that of the metal body, which greatly reduces the heat transfer rate between the two bodies, thereby ensuring the stability of the refrigerant temperature in the first connecting channel 41 and the second connecting channel 45 and optimizing the thermal performance of the air conditioning system.

[0060] Furthermore, in this embodiment, the first valve island body 4 and the second valve island body 44 achieve functional integration through the internal first connecting channel 41 and the second connecting channel 45, replacing the traditionally dispersed multiple valves and connecting pipelines. This integrates the valves that originally needed to be arranged separately into the first valve island body 4 and the second valve island body 44, reducing the number of independent valves, lowering their weight, and saving on material costs. At the same time, since the high-pressure side and low-pressure side pipelines are separated, if a pipeline on one side fails, only the equipment on the corresponding pipeline needs to be replaced, without having to replace both the high-pressure side and low-pressure side pipelines, thus reducing maintenance costs.

[0061] like Figure 4 As shown, the valve island module 100 according to some embodiments of this application includes: a first plate 5 and a second plate 51, the first plate 5 and the second plate 51 are attached to each other in the thickness direction, a flow channel groove 52 is formed on at least one wall surface of the first plate 5 and the second plate 51 facing each other, a communication channel 11 is defined in the flow channel groove 52 and located between the first plate 5 and the second plate 51, and a flow channel interface 12 communicating with the communication channel 11 is formed on one of the first plate 5 and the second plate 51.

[0062] According to some embodiments of this application, the valve island module 100 is connected by a first plate 5 and a second plate 51 in the thickness direction. Flow channels 52 are provided on the opposing walls of the two plates. After being attached, a connecting channel 11 is formed between the plates, thereby replacing the traditional medium transportation path of refrigerant or gas formed by welding segmented pipes. This structure does not need to consider the gap 32 that must be reserved when connecting segmented pipes in the traditional way, as well as the minimum straight section size and minimum bending radius size of the pipes. It greatly improves the integration of the air conditioning pipe system and reduces the space occupation of the air conditioning pipes. Compared with the traditional scattered segmented pipe settings, it significantly reduces the space occupation. At the same time, since it is not necessary to form a medium passage by welding multiple pipe segments, it directly reduces the large number of weld points generated by welding connections in the traditional way, avoiding the problem of many weld points.

[0063] According to some embodiments of the present application, the valve island module 100 has two or more flow channel interfaces 12, and at least one is provided on the first plate 5 and the second plate 51 respectively; or the flow channel interfaces 12 are multiple, and the multiple flow channel interfaces 12 are arranged on the first plate 5 or the second plate 51.

[0064] The arrangement of the aforementioned flow channel interfaces 12 can all be adapted to the connecting channel 11 between the first plate 5 and the second plate 51. At least one flow channel interface 12 is provided on the first plate 5 and the second plate 51 respectively. Since each plate carries at least one flow channel interface 12 and each interface is connected to the connecting channel 11 between the plates, the medium can enter the connecting channel 11 from the interface of one plate and then flow out from the interface of the other plate. This allows for more flexible matching of the medium connection requirements of external components at different locations. There is no need to adjust the orientation or position of the interface through additional pipeline conversion, which shortens the transport path of the medium between the external components and the connecting channel 11 and reduces the space occupied by the path.

[0065] As for the flow channel interface 12, which is arranged on the first plate 5 or the second plate 51, multiple interfaces are concentrated on the same plate and connected to the connecting channel 11. This allows the medium connection ends of multiple external components to be concentrated on the same side of the valve module assembly, which facilitates the centralized arrangement and management of external pipelines, reduces the crossing or detour of external pipelines caused by their dispersed connection to different plates, and reduces the complexity of the external pipeline system.

[0066] like Figure 5 As shown, in the valve island module 100 according to some embodiments of this application, the thickness of the first plate 5 is n, the thickness of the second plate 51 is m, and the depth of the flow channel groove 52 is d, and satisfies: 0 < d / m ≤ 10, 0 < d / n ≤ 10.

[0067] It is understandable that when 0 < d / m ≤ 1 and 0 < d / n ≤ 1, the depth of the channel groove 52 is less than the corresponding plate thickness. This means that the channel groove 52 is only opened inside the plate and does not penetrate the plate. At this time, the ungrooved area of ​​the plate can form a complete structural support, which can effectively resist the pressure impact generated when the refrigerant flows in the channel, and avoid the structural strength reduction of the plate due to excessive groove depth. At the same time, the shallower channel groove 52 can make the connecting channel 11 formed after the two plates are attached have a more uniform wall thickness, reduce the local stress concentration caused by uneven wall thickness, and ensure the structural reliability of the channel in long-term operation.

[0068] When 1 < d / m ≤ 10 and 1 < d / n ≤ 10, the depth of the channel groove 52 is greater than the corresponding plate thickness. In this case, the channel groove 52 can form a deeper recess on the plate. With the adhesion of another plate, a connecting channel 11 with a larger cross-sectional area can be constructed, which improves the flow capacity of the refrigerant and meets the needs of large-flow refrigerant transportation. At the same time, although the groove depth in this range exceeds the plate thickness, the limitation of d / m ≤ and d / n ≤ can avoid the channel groove 52 being too deep, which would cause the remaining structure of the plate to be too thin. This ensures that the plate can still maintain its basic load-bearing capacity and prevents deformation during assembly or use. By controlling the ratio of the depth of the channel groove 52 to the plate thickness, the balance and optimization of the function of the connecting channel 11 and the structural performance of the plate are achieved without changing the basic structure of the plate and the channel groove 52.

[0069] According to some embodiments of the present application, the valve island module has a flow channel formed inside the support member, and the support member is connected to the flow channel interface on the surface of the valve island body 1, so that the flow channel is connected to the connecting channel through the flow channel interface.

[0070] It is understood that, in addition to supporting the valve island body 1, the support component forms a flow channel inside it, which connects to the flow channel interface 12 on the surface of the valve island body 1. This allows external fluid to be directly introduced into the connecting channel 11 of the valve island body 1, eliminating the need for an additional independent fluid transmission pipeline to connect the external fluid source to the valve island body 1. This reduces the number of pipelines and connection nodes in the system, avoiding the increased weight and leakage risks caused by additional pipelines and connection nodes, while simplifying the overall structural layout of the system. Furthermore, since the support component is directly connected to the valve island body 1 and the flow channel is integrated inside the support component, the support component in this application simultaneously serves as both a support and a fluid transmission function. Only one installation is required to complete the support fixation and flow channel docking, reducing installation procedures and debugging steps, and lowering installation and time costs.

[0071] According to some embodiments of the present application, the valve island module has a support structure as a flow channel tube, and a flow channel is formed inside the flow channel tube.

[0072] Furthermore, when the support component is constructed as a flow channel pipe, the internal flow channel can be directly connected to the flow channel interface 12 of the valve island body 1. While supporting and fixing the valve island body 1, it can stably transmit fluid through the tubular flow channel. The installation method of the tubular support component is flexible, and the installation angle can be adjusted according to the system space layout to adapt to different pipeline routing requirements. The flow channel pipe type support component integrates support and flow channel functions in a single structure, eliminating the need to set up separate support components and flow channel components. This reduces the connection nodes in the system and lowers the risk of leakage caused by the connection of multiple components. At the same time, it can be flexibly selected according to the space size of the air conditioning system, the number of fluid transmission paths, and other requirements, improving the adaptability of the valve island module.

[0073] According to some embodiments of this application, the valve island module has a support member connected to the top, side, or bottom of the valve island body 1.

[0074] First, the support component can be connected to the top, side, or bottom of the valve island body 1, allowing for multi-position connections to adapt to different installation layout requirements. When there is a fixed point at the top of the installation space, the support component can be connected to the top for suspended fixation; when there is a support structure on the side, it can be connected to the side for side-mounted positioning; and when it needs to be fixed to a flat carrier, it can be connected to the bottom for seated installation, eliminating the need for additional environmental modifications or customized structures, significantly improving installation adaptability. Second, by connecting the support component at different positions, the installation posture and height of the valve island body 1 can be precisely adjusted, ensuring smooth connection between the interface and external components, reducing adjustment procedures, and providing stable force support for the body to prevent deformation and ensure the integrity of the internal communication channels. Finally, the connection between the support component and the body forms an independent support system, eliminating the need to rely on the docking structure for load-bearing, preventing interface failure due to additional stress, ensuring support reliability, and improving overall operational stability.

[0075] According to some embodiments of the present application, the valve island module has a support structure as a valve plate 8, and the valve plate 8 has positioning holes and / or screw holes on both sides.

[0076] It is understandable that when the support component is constructed as valve plate 8, valve plate 8 is fixed on valve island body 1. Positioning holes and screw holes are provided on both sides of valve plate 8. Valve plate 8 is fixed to valve island body 1 by screws, and fixing screw holes are provided on valve plate 8 to connect valve island module 100 with valve plate 8. At the same time, valve plate 8 is also provided with positioning holes, which are suitable for connecting with other fixed components in air conditioner to support valve island module.

[0077] like Figure 6 As shown, the valve island assembly 200 according to an embodiment of this application is briefly described below. The valve island assembly 200 according to an embodiment of this application includes valve island modules 100 of any of the above embodiments. Multiple valve island modules 100 are constructed. Since multiple valve island modules 100 of any of the above embodiments are provided on the valve island assembly 200 according to this embodiment, the valve island assembly 200 replaces multiple welded pipe sections through a single valve island module 100 via a connecting channel 11. When multiple valve island modules 100 form the valve island assembly 200, the valve island assembly 200 does not need to have a separate channel for each channel. The redundant straight sections, bending structures, and welded parts can be expanded to include more fluid transmission paths simply by combining the interfaces of the valve island module 100. This significantly reduces the overall weight of the component compared to traditional multi-path piping systems, further enhancing the weight reduction effect. At the same time, the valve island assembly 200, composed of multiple valve island modules 100, can flexibly increase or decrease the number of valve island modules 100 according to actual fluid transmission needs. This greatly reduces the workload of re-cutting and welding pipes required for functional adjustments in traditional piping systems, significantly improving installation efficiency and reducing costs and time losses caused by pipe modifications.

[0078] A valve island assembly 200 according to some embodiments of this application includes: a plate heat exchanger 7 having a plurality of plate heat exchanger interfaces; three valve island modules 100, namely a first valve island module 71, a second valve island module 72, and a third valve island module 73, wherein the first valve island module 71 and the second valve island module 72 are respectively connected to the plate heat exchanger 7, and a first valve island flow channel and a second valve island flow channel are respectively formed inside the first valve island module 71 and the second valve island flow channel are respectively connected to different plate heat exchanger interfaces; the first valve island module 71 is provided with a first valve pipe 711 connected to the first valve island flow channel; the third valve island module 73 has a third valve island flow channel and is also provided with a second valve pipe 731.

[0079] The first valve island module 71, the second valve island module 72, and the third valve island module 73 are connected by internally formed first valve island flow channels, second valve island flow channels, and third valve island flow channels. The first valve island flow channels and second valve island flow channels are connected to the interfaces of different plate heat exchangers 7. This replaces the traditional technology that relies on multiple welded pipe sections to connect various devices. It avoids the problems of traditional pipe connections, which require each pipe section to reserve a straight section and a minimum bending radius to meet the bending process requirements, and adjacent pipes need to be welded together, resulting in an increase in the total length of the pipe and an expansion of the space occupation. The internal flow channels of the valve island are an integrated structure, which does not require additional redundant lines for bending, nor does it require welding to achieve inter-segment connections. This not only shortens the effective length of the fluid transmission path, but also reduces the number of welding nodes, thereby significantly improving the integration of the pipe system and greatly reducing the space occupation of the pipes inside the air conditioner outdoor unit. At the same time, due to the shortened pipe length and the reduction of welding nodes, the consumption of raw materials and welding process costs are reduced, solving the problems of long pipes, large space occupation, and high costs under the traditional connection method.

[0080] It should be noted that the first valve pipe 711 is adapted to be connected to the high-pressure valve 10, the second valve pipe 731 is adapted to be connected to the low-pressure valve 20, and the third valve island module 73 is connected to the four-way valve 74.

[0081] like Figure 6 As shown, the valve plate 8 is connected to the first valve island module 71 and the second valve island module 72 on both sides by screws.

[0082] The air conditioner according to an embodiment of this application is briefly described below.

[0083] The air conditioner according to the embodiments of this application includes a valve island module 100 or a valve island assembly 200 of any of the above embodiments. Since the air conditioner according to this embodiment is provided with a valve island module 100 or a valve island assembly 200 of any of the above embodiments, the air conditioner has the requirement of multi-channel fluid transmission. The connecting channel 11 of the valve island module 100 can replace the original multi-section welded pipes of the air conditioner. The valve island assembly 200 can realize the integrated transmission of multi-channel fluids through the combination of multiple valve island modules 100, which can significantly reduce the total length of the internal pipes of the air conditioner, the number of welding points, and the redundant structure caused by bending requirements, directly reducing the overall weight of the air conditioner, and at the same time reducing the amount of pipe material used. Firstly, it controls production costs. Secondly, the interface of the valve island module 100 / valve island assembly 200 simplifies the docking process with components such as the compressor, heat exchanger, and solenoid valve inside the air conditioner, eliminating the need for segmented pipe cutting, bending, and welding, thus shortening the assembly period. Furthermore, the integrated structure of the valve island module 100 / valve island assembly 200 is more compact, effectively utilizing the limited space inside the air conditioner and improving the regularity of the internal structure. At the same time, the connecting channel 11 of the valve island module 100 / valve island assembly 200 has no welding sealing risks, which can reduce the risk of air conditioner failures such as decreased cooling / heating efficiency and refrigerant leakage caused by pipe welding leaks, ensuring long-term stable operation of the air conditioner.
