[0002] With the improvement of people's living standards, air conditioners have become an indispensable appliance in daily life. Air conditioners can regulate indoor temperature to improve user comfort. In related technologies, the piping system of the outdoor unit of an air conditioner includes multiple devices connected by pipes. In this connection method, because the pipes are connected by welding sections together, each section of pipe must have a straight section and a bending radius. Both the straight section and the bending radius have a minimum size, which makes it impossible to make the piping system more compact. Therefore, this connection method uses long pipes, occupies a lot of space, and has high material and processing costs. At the same time, the connection of various devices through pipes makes the piping system complex, with many welding points, and the risk of fluid leakage at the welding points is high.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The valve island assembly 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0026] like Figures 1-4 , Figures 13-16 and Figures 21-22 As shown, a valve island assembly 100 according to an embodiment of the present invention includes: a plate heat exchanger assembly 10 and a second valve island 20.

[0027] Specifically, the plate heat exchanger assembly 10 includes a plate heat exchanger 11 and a first valve island 12. The plate heat exchanger 11 forms a plate heat exchanger interface 111, and the first valve island 12 is connected to the plate heat exchanger 11 and communicates with the plate heat exchanger interface 111. A second valve island 20 is connected to a first pressure valve 21, and the second valve island 20 is detachably connected to the plate heat exchanger assembly 10.

[0028] In related technologies, the piping system of an air conditioner outdoor unit includes multiple devices connected by pipes. In this connection method, the pipes are connected together by welding sections of pipe. Each section of pipe must have a straight section and a bending radius. Both the straight section and the bending radius have a minimum size, which makes it impossible to make the piping system more compact. Therefore, this connection method uses long pipes, occupies a lot of space, and has high material and processing costs. At the same time, the connection of various devices through pipes makes the piping system complex, with many welding points, and the risk of fluid leakage at the welding point locations is high.

[0029] In this application, the first valve island 12 and the second valve island 20 can be used to integrate and install other components to achieve communication between these components and the plate heat exchanger 11. For example, in some embodiments, the first valve island 12 can integrate and install filters, throttle valves 92, etc., and the second valve island 20 can integrate and install multi-way valves 91, throttle valves 92, filters, etc. Furthermore, the first valve island 12 and the second valve island 20 have internally formed valve island flow channels, which can achieve communication between different components to achieve fluid flow. For example, the first valve island 12 flow channel of the first valve island 12 can be directly connected and communicated with the plate heat exchanger interface 111 of the plate heat exchanger 11, and the second valve island 20 flow channel of the second valve island 20 can be directly or indirectly connected and communicated with the plate heat exchanger interface 111. For example, the second valve island 20 flow channel of the second valve island 20 can be connected and communicated with the first valve island 12 flow channel of the first valve island 12.

[0030] By setting up a first valve island 12 and a second valve island 20, the traditional technology of connecting various devices by relying on multiple welded pipe sections can be replaced. This 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 pipes and an expansion of the space occupied. The internal flow channel of the valve island is an integrated structure, which eliminates the need for additional redundant lines required for bending and the need for inter-segment connections through welding. 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 occupied by 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.

[0031] Meanwhile, by setting the first valve island 12 and the second valve island 20, the originally dispersed fluid transmission paths are concentrated in the internal flow channel of the valve island, which greatly simplifies the overall structure of the pipeline system. Due to the reduction in the number of weld points in this application, the risk of leakage caused by welding defects is reduced, and the operational reliability of the pipeline system is improved.

[0032] In addition, the first valve island 12 and the plate heat exchanger 11 are integrated into a plate heat exchanger assembly 10, and the second valve island 20 is connected to the plate heat exchanger assembly 10, forming an integrated module. This further optimizes the internal spatial layout of the air conditioner outdoor unit and improves the overall structural compactness. On the other hand, the various components of the air conditioner outdoor unit will vibrate during operation. Integrating them into an integrated module to improve rigidity also helps to reduce the superposition of vibrations, effectively reducing the impact of vibration on the flow channel sealing and improving the service life of the piping system.

[0033] During use, when a component malfunctions and needs replacement or repair, replacing or disassembling the entire valve island assembly 100 would result in high maintenance costs and significant operational difficulties. In this application, the second valve island 20 is detachably connected to the plate heat exchanger assembly 10. This allows operators to separate the second valve island 20 from the plate heat exchanger assembly 10 before repairing or replacing the faulty component. This eliminates the need to replace modules that do not contain the faulty component, reducing maintenance costs, while modules containing the faulty component can be disassembled for individual operation, improving the convenience of replacement or repair.

[0034] Furthermore, the first valve island 12 and the second valve island 20 are two separately configured valve islands. The first valve island 12 is directly connected to the plate heat exchanger 11, while the second valve island 20 does not need to be directly connected to the plate heat exchanger 11. Therefore, the material selection for the first valve island 12 and the second valve island 20 can be more flexible and they do not interfere with each other. For example, the first valve island 12 can be made of the same material as the plate heat exchanger 11, such as stainless steel, so that the first valve island 12 and the plate heat exchanger 11 can be directly welded together, eliminating the need for intermediate piping, and the weld surface is less prone to breakage. The second valve island 20 can be made of a different material than the plate heat exchanger 11, such as aluminum alloy, which is lightweight, low-cost, and easy to process.

[0035] In short, the valve island assembly 100 according to this utility model embodiment replaces the traditional multi-connection welded pipeline with the first valve island 12 and the second valve island 20, eliminating the need for welding nodes and straight sections and minimum bending radii required for bending, reducing pipeline length dependence, improving pipeline integration and reducing space occupation; it also reduces the number of welding points, simplifies the pipeline system structure, avoids the hidden dangers of complex pipelines, and reduces costs due to pipeline shortening and structural simplification. In addition, the second valve island 20 is detachably connected to the plate heat exchanger assembly 10, allowing the second valve island 20 and the plate heat exchanger assembly 10 to be disassembled separately for component repair and replacement, reducing maintenance costs and operational difficulty.

[0036] According to some embodiments of this utility model, such as Figures 1-2 , Figures 13-16 and Figures 21-22 As shown, the valve island assembly 100 also includes a first support member 40 and a second support member 50.

[0037] The plate heat exchanger assembly 10 is mounted on the first support member 40, and the second valve island 20 is mounted on the second support member 50. The second support member 50 is connected to the first support member 40. By connecting the plate heat exchanger 11, the first valve island 12, and the second valve island 20, the first support member 40 and the second support member 50 can transmit and disperse the vibrations generated by each component, avoiding excessive vibration amplitude of a single component or the superposition of vibrations, thus effectively reducing vibration. This reduces the impact of vibration on the sealing performance of the internal flow channels of the valve island and the sealing performance of the connection between the valve island and the plate heat exchanger 11, indirectly ensuring the stability of fluid transmission and extending the service life of the pipeline system.

[0038] In some embodiments, such as Figures 11-22 As shown, the first support member 40 and the second support member 50 are detachably connected. When it is necessary to separate the second valve island 20 from the plate heat exchanger assembly 10, the connection between the first support member 40 and the second support member 50 can be disassembled, which is simple and convenient.

[0039] In the embodiments of this application, the detachable connection method can be flexibly set, and can be, but is not limited to, fastener 90 connection, snap-fit, etc.; the fixed connection method can be, but is not limited to, welding, integral molding connection, etc. Among them, the fastener 90 connection has high strength, is easy to disassemble and assemble, and is not easily damaged after repeated disassembly and assembly, which helps to improve service life. Fastener 90 can be bolts, screws, etc.

[0040] In other embodiments, such as Figures 1-9 As shown, the first support member 40 and the second support member 50 can be integrally formed to improve support stability and the effect of transmitting and dispersing vibration. In addition, the plate heat exchanger assembly 10 is detachably connected to the first support member 40; or the second valve island 20 is detachably connected to the second support member 50; or, the plate heat exchanger assembly 10 is detachably connected to the first support member 40, and the second valve island 20 is detachably connected to the second support member 50.

[0041] Therefore, when it is necessary to separate the second valve island 20 from the plate heat exchanger assembly 10, the plate heat exchanger assembly 10 can be separated from the first support member 40, or the second valve island 20 can be separated from the second support member 50, so as to facilitate individual repair or replacement of the components.

[0042] In some embodiments of this utility model, such as Figures 1-2 , Figures 13-16 and Figures 21-22As shown, the valve island assembly 100 also includes a valve plate 30, which is connected to the plate heat exchanger assembly 10. A first pressure valve 21 is mounted on the valve plate 30, and a second pressure valve 15 is connected to the plate heat exchanger assembly 10 and mounted on the valve plate 30. The first pressure valve 21 is integrated not only into the second valve island 20 but also mounted on the valve plate 30, and the second pressure valve 15 is integrated not only into the plate heat exchanger assembly 10 but also mounted on the valve plate 30. This improves the installation stability of the first pressure valve 21 and the second pressure valve 15 and reduces the vibration of the first pressure valve 21 and the second pressure valve 15 during operation.

[0043] Furthermore, the valve plate 30 is detachably connected to the plate heat exchanger assembly 10, and the first pressure valve 21 and the second pressure valve 15 are detachably mounted on the valve plate 30. By separating the valve plate 30 and the plate heat exchanger assembly 10, and the second pressure valve 15 and the valve plate 30, the plate heat exchanger assembly 10 and the second valve island 20 can be separated. Furthermore, by separating the first pressure valve 21 and the valve plate 30, the second valve island 20 and the valve plate 30 can be separated. This allows for the individual disassembly of the plate heat exchanger assembly 10 and the second valve island 20 without the need to disassemble or replace the valve plate 30 together.

[0044] The connection structure of components such as the first support member 40, the second support member 50, and the valve plate 30 according to some embodiments of the present invention is described below with reference to the accompanying drawings.

[0045] According to some embodiments of this utility model, such as Figure 2 , Figure 5 , Figures 11-12 , Figures 14-19 and Figures 21-22 As shown, the first support member 40 includes a first connecting plate 41 and a second connecting plate 42. The first connecting plate 41 is connected to the plate heat exchanger assembly 10, and the second connecting plate 42 is located on one side of the plate heat exchanger assembly 10 in the horizontal direction and is connected to the edge of the first connecting plate 41. The second support member 50 includes a third connecting plate 51, and the second valve island 20 is supported and connected to the third connecting plate 51. The third connecting plate 51 is connected to the second connecting plate 42.

[0046] Here, the third connecting plate 51 and the second connecting plate 42 can be directly connected or indirectly connected. For example, in some embodiments, the third connecting plate 51 extends with a fourth connecting plate 52 bent toward the direction close to the second connecting plate 42, and the second connecting plate 42 is connected to the fourth connecting plate 52. Alternatively, the second connecting plate 42 extends with a flange bent toward the direction close to the third connecting plate 51, and the flange is connected to the third connecting plate 51.

[0047] The first connecting plate 41 and the second connecting plate 42 generally form an L-shaped bent plate structure, and the third connecting plate 51 and the fourth connecting plate 52 generally form an L-shaped bent plate structure, so that the second connecting plate 42 and the fourth connecting plate 52 can be connected from one side of the plate heat exchanger assembly 10 in the horizontal direction. This not only allows the connection structure between the first connecting plate 41 and the plate heat exchanger assembly 10 and the connection structure between the third connecting plate 51 and the second valve island 20 to be horizontally staggered, which facilitates the connection operation, but also allows the second connecting plate 42 and the fourth connecting plate 52 to occupy less space, which is beneficial to improving the structural compactness.

[0048] In some embodiments where the first support member 40 and the second support member 50 are integrally formed, such as... Figure 2 and Figure 5 As shown, the second connecting plate 42 and the fourth connecting plate 52 are integrally formed. In other words, the first support member 40 and the second support member 50 can be obtained by sheet metal processing from a complete plate, which simplifies the processing procedure.

[0049] In some embodiments where the first support member 40 and the second support member 50 are detachably connected, such as Figures 11-12 , Figures 14-19 and Figures 21-22 As shown, the third connecting plate 51 is detachably connected to the second connecting plate 42. For example, the second connecting plate 42 and the fourth connecting plate 52 can be connected by fasteners 90. The fasteners 90 enable the detachable connection between the second connecting plate 42 and the fourth connecting plate 52, thereby enabling the detachable connection between the first support member 40 and the second support member 50. This facilitates the disassembly of the first support member 40 and the second support member 50 when it is necessary to separate the second valve island 20 and the plate heat exchanger assembly 10, improving maintenance convenience and reducing the cost of replacing parts.

[0050] Optionally, the second connecting plate 42 is provided with a sixth connecting hole 421, and the fourth connecting plate 52 is provided with a seventh connecting hole 521. The fastener 90 passes through the sixth connecting hole 421 and the seventh connecting hole 521 and is locked (by a nut or by providing an internal thread in the connecting hole) to connect the second connecting plate 42 and the fourth connecting plate 52.

[0051] Optionally, such as Figure 16 and Figure 22 As shown, in the horizontal direction perpendicular to the penetration direction of the sixth connecting hole 421, the sixth connecting hole 421 is staggered from the plate switch assembly 10, so that the plate switch assembly 10 will not interfere with the disassembly and assembly of the fastener 90, making the disassembly and assembly operation more convenient.

[0052] According to some embodiments of this utility model, such as Figures 5-8 , Figures 11-12 and Figures 21-22As shown, the first support member 40 includes a first connecting plate 41. The first connecting plate 41 is supported on the lower side of the plate heat exchange assembly 10, and the first connecting plate 41 has a first connecting hole 411 that extends vertically through it. A fastener 90 passes through the first connecting hole 411 and is connected to the plate heat exchange assembly 10.

[0053] This allows for a detachable connection between the first support member 40 and the plate heat exchanger assembly 10. When it is necessary to separate the plate heat exchanger assembly 10 and the second valve island 20, or to disassemble the plate heat exchanger assembly 10, the connection between the first support member 40 and the plate heat exchanger assembly 10 can be detached, facilitating the individual disassembly of the plate heat exchanger assembly 10. Furthermore, the connection between the first connecting plate 41 and the plate heat exchanger assembly 10 can be detached and assembled from the lower side of the first connecting plate 41, making it less likely to be obstructed by other components and further simplifying the detachment and assembly process.

[0054] It is worth noting that the fastener 90 can be integrated into the circuit board heat exchanger assembly 10, or the circuit board heat exchanger assembly 10 can have a connection hole through which the fastener 90 passes. For example Figures 5-8 As shown, the fastener 90 is integrated into the plate heat exchanger assembly 10. The fastener 90 passes through the first connecting hole 411, and the free end of the fastener 90 is locked with the nut to realize the connection between the plate heat exchanger assembly 10 and the first connecting plate 41.

[0055] According to some other embodiments of this utility model, such as Figures 15-18 As shown, the first connecting plate 41 is sandwiched between the plate heat exchanger 11 and the first valve island 12, and the first connecting plate 41 is fixedly connected to both the plate heat exchanger 11 and the first valve island 12. In the above embodiment, it is beneficial to increase the connection area between the first connecting plate 41 and the plate heat exchanger assembly 10, thereby improving the connection strength. The connection method can be, but is not limited to, welding.

[0056] It is worth noting that the first connecting plate 41 can be arranged separately from the plate heat exchanger interface 111 of the plate heat exchanger 11, or the first connecting plate 41 can be provided with through holes for the plate heat exchanger interface 111 to pass through.

[0057] According to some embodiments of this utility model, such as Figure 5 , Figures 8-12 and Figures 19-20 As shown, the second support member 50 includes a third connecting plate 51, which has a second connecting hole 511 extending vertically through it. The second valve island 20 has a third connecting hole 22 extending vertically through it. Fasteners 90 pass through the third connecting hole 22 and the second connecting hole 511 to connect the second valve island 20 and the second support member 50.

[0058] This allows for a detachable connection between the second valve island 20 and the second support member 50. When it is necessary to separate the second valve island 20 from the plate heat exchanger assembly 10 or to disassemble the second valve island 20 separately, the connection between the second valve island 20 and the second support member 50 can be detached. The third connecting plate 51 and the second valve island 20 are arranged vertically, and the fasteners 90 can be inserted in the vertical direction without being easily obstructed or interfered with by other components, making disassembly and assembly operations more convenient.

[0059] In some embodiments, such as Figure 5 , Figures 11-12 and Figure 19 As shown, the air conditioner 1000 includes a gas-liquid separator 60. The second support member 50 can be supported and installed on the gas-liquid separator 60, so that the second valve island 20 and the second support member 50 can be integrated with the gas-liquid separator 60 into a whole, so as to further improve the overall structural rigidity and structural reliability, which is beneficial to reduce vibration and facilitate the flow channel communication between the gas-liquid separator 60 and the second valve island 20 or the first valve island 12.

[0060] Here, the second support 50 and the gas-liquid separator 60 can be fixedly connected by welding or other means, or they can be detachably connected by fasteners 90 or other means.

[0061] For example, continue to refer to Figure 5 , Figures 11-12 and Figure 19 The gas-liquid separator 60 has a gas distribution pipe 61 at its top, which can be used to connect with the second valve island 20 to achieve flow channel connection. The second support member 50 has a through hole 512, through which the gas distribution pipe 61 passes, and the second support member 50 is welded to the gas-liquid separator 60. By providing the through hole 512, the connection between the second support member 50 and the gas-liquid separator 60 can be avoided, which helps to increase the welding area and improve the connection strength. In addition, the cooperation between the gas distribution pipe 61 and the through hole 512 can play a certain limiting role in the horizontal direction, which also helps to improve the connection stability.

[0062] In some embodiments including the valve plate 30, the valve plate 30 can be used to support and fix the pressure valve. For example, in some embodiments, the plate heat exchanger assembly 10 includes a second pressure valve 15, and both the first pressure valve 21 and the second pressure valve 15 are detachably mounted on the valve plate 30 to reduce vibration during the operation of the pressure valve. Optionally, the first pressure valve 21 is a low-pressure valve, and the second pressure valve 15 is a high-pressure valve.

[0063] In some embodiments, such as Figures 1-7As shown, a fifth connecting plate 13 is provided on one side of the plate heat exchanger 11 in the horizontal direction, and the valve plate 30 is connected to the fifth connecting plate 13 by a fastener 90. Specifically, the fastener 90 passes through the valve plate 30 and the fifth connecting plate 13 in the horizontal direction to achieve a detachable connection between the valve plate 30 and the plate heat exchanger 11. The fastener 90 is not easily obstructed by other components, making it easy to assemble and disassemble.

[0064] For example, the plate heat exchanger 11 has a fifth connecting plate 13 on one side along the first horizontal direction, and the valve plate 30 includes a support plate and a connecting plate. The connecting plate is connected to the lower edge of the support plate. The support plate is used to install a pressure valve, and the connecting plate is used to connect with the fifth connecting plate 13.

[0065] In other embodiments, such as Figures 13-22 As shown, the plate heat exchanger assembly 10 also includes a third valve island 14, which is connected to the plate heat exchanger 11 and communicates with the plate heat exchanger interface 111. By setting the third valve island 14, flow path integration can be further achieved, thereby reducing the number of tubes connected to the plate heat exchanger 11, reducing weld points, and simplifying piping.

[0066] Furthermore, the first valve island 12 and the third valve island 14 are respectively connected to the valve plate 30 by fasteners 90. By disassembling the connection between the first valve island 12 and the third valve island 14 and the valve plate 30, the valve plate 30 can be separated from the valve assembly 10, so as to facilitate the individual disassembly of the valve plate 30 or the second valve island 20 connected to the valve plate 30.

[0067] For example, the first valve island 12 and the third valve island 14 can be arranged along a second horizontal direction. The valve plate 30 includes a support plate and two connecting plates. The two connecting plates are respectively connected to both ends of the support plate in the second horizontal direction. The two connecting plates are located on the opposite sides of the first valve island 12 and the third valve island 14. The connecting plates are provided with an eighth connecting hole 32, and the opposite sides of the first valve island 12 and the third valve island 14 are each provided with a ninth connecting hole 17. Fasteners 90 pass through the eighth connecting hole 32 and the corresponding ninth connecting hole 17 along the second horizontal direction to achieve a detachable connection between the valve plate 30 and the plate heat exchanger assembly 10.

[0068] In some embodiments, such as Figure 1 and Figure 2 As shown, the valve plate 30 has a downwardly recessed mounting groove 31, in which the first pressure valve 21 and the second pressure valve 15 are supported and installed. The bottom wall of the mounting groove 31 can provide support for the pressure valves (such as the first pressure valve 21 and the second pressure valve 15), and the side wall of the mounting groove 31 can provide a limiting function for the pressure valves, thereby allowing the pressure valves to be mounted on the valve plate 30.

[0069] In some specific embodiments, such as Figure 2 , Figures 14-15 and Figures 21-22 As shown, the pressure valve and valve plate 30 can also be connected by fasteners 90, which can be inserted into the pressure valve and valve plate 30 in a horizontal direction (such as the first horizontal direction). This not only improves the stability of the valve plate 30 for the installation of the pressure valve and enhances the vibration reduction effect, but also enables a detachable connection between the pressure valve and valve plate 30, facilitating the separate disassembly of the plate heat exchanger assembly 10 and the second valve island 20.

[0070] According to some embodiments of this utility model, such as Figures 1-7 As shown, at least one plate heat exchanger interface 111 is provided with a connecting pipe 113, one of which is connected to a second pressure valve 15. The second pressure valve 15 is detachably connected to the valve plate 30. The second pressure valve 15 and the plate heat exchanger interface 111 are connected by the connecting pipe 113. The length of the connecting pipe 113 can be set to be relatively short to reduce cost and vibration. The detachable connection between the second pressure valve 15 and the valve plate 30 facilitates the individual disassembly of the valve plate 30 and the second valve island 20 connected to the valve plate 30.

[0071] According to some other embodiments of this utility model, such as Figures 13-18 As shown, a connecting end face 112 is formed on the plate heat exchanger 11, and the connecting end face 112 is provided with a plurality of plate heat exchanger interfaces 111. A first connecting wall 141 is formed at the bottom of the third valve island 14. The first connecting wall 141 is provided with at least one first flow channel interface. The first connecting wall 141 is directly opposite to the connecting end face 112 and welded together so that the first flow channel interface is connected to the plate heat exchanger interface 111. A second pressure valve 15 is connected to the third valve island 14, and the second pressure valve 15 is detachably connected to the valve plate 30.

[0072] The connecting end face 112 of the plate heat exchanger 11 is directly opposite to the first connecting wall 141 of the third valve island 14, and the first flow channel interface and the plate heat exchanger interface 111 are respectively located on the directly opposite first connecting wall 141 and connecting end face 112, so that the connection between the two can be initially aligned in the early stage of assembly, avoiding assembly deviation caused by interface misalignment.

[0073] In addition, the first connecting wall 141 and the connecting end face 112 can form a clear positioning guide by the cooperation of the protrusion and the recess. During assembly, it is only necessary to insert the protrusion into the recess to quickly and accurately align the first flow channel interface with the corresponding plate heat exchange interface 111. There is no need to use additional tools to adjust the interface position, which greatly reduces the difficulty of assembly positioning and significantly improves the convenience of connection operation.

[0074] Regarding the connection between the first valve island 12 and the plate heat exchanger 11, in some embodiments, such as Figures 17-18As shown, a connecting end face 112 is formed on the plate heat exchanger 11, and the connecting end face 112 is provided with a plurality of plate heat exchanger interfaces 111. A second connecting wall 121 is formed at the bottom of the first valve island 12, and the second connecting wall 121 is provided with at least one second flow channel interface. The second connecting wall 121 is directly opposite to the connecting end face 112 and welded together so that the second flow channel interface communicates with the plate heat exchanger interface 111.

[0075] The direct alignment of the second connecting wall 121 and the connecting end face 112 of the first valve island 12 also enables the initial positioning of the second flow channel interface and the corresponding plate heat exchanger interface 111. Optionally, the cooperation structure of the protrusions and recesses of the second connecting wall 121 and the connecting end face 112 can also achieve rapid alignment of the second flow channel interface on the second connecting wall 121 with the corresponding plate heat exchanger interface 111, further enhancing the convenience of the overall connection operation.

[0076] The second connecting wall 121 is welded to the connecting end face 112, which also helps to increase the area of ​​the welding connection and improve the reliability of the connection; and eliminates the intermediate connecting pipe 113 body, making the structure more compact and the pipeline system simpler.

[0077] In some embodiments, such as Figures 6-7 As shown, the plate heat exchanger 11 is provided with a fourth connection hole 114, the first valve island 12 is provided with a fifth connection hole 123, and the fastener 90 passes through the fifth connection hole 123 and the fourth connection hole 114 to connect the first valve island 12 and the plate heat exchanger 11.

[0078] The above connection method not only enables the detachable connection between the first valve island 12 and the plate heat exchanger 11, allowing for individual replacement and maintenance of components, but also ensures that the connection between the first valve island 12 and the plate heat exchanger 11 is not limited by material. The first valve island 12 can be made of the same material as the plate heat exchanger 11, or it can be made of a different material. For example, the first valve island 12 can be made of aluminum alloy to reduce weight and cost, while the plate heat exchanger 11 can be made of stainless steel.

[0079] According to some embodiments of this utility model, such as Figures 1-2 , Figures 11-16 and Figures 21-22 As shown, the first support member 40 or the plate heat exchanger 11 is provided with a sixth connecting plate 70, and the valve island assembly 100 also includes a third support member 80. The third support member 80 is installed on the housing 200 of the air conditioner 1000 and is connected to the sixth connecting plate 70.

[0080] Therefore, the first support member 40 provides fixed support for the valve island assembly 100 within the housing 200. This effectively secures the valve island assembly 100 within the housing 200, constraining its position within the housing 200. Simultaneously, it supports the valve island assembly 100 and fixes the assembly positions of various components, achieving space optimization and minimizing the number of components. Furthermore, the first support member 40 provides stable support for the valve island assembly 100, reducing the likelihood of vibration and improving the stability of its installation.

[0081] For example, the housing 200 includes an outer shell and a partition. The partition is located inside the outer shell and divides the space inside the outer shell into a first chamber and a second chamber. The compressor 300 and valve island assembly 100 are located in the first chamber, and the outdoor heat exchanger and outdoor fan are located in the second chamber. The third support member 80 may include a support platform and fixing structures located at both ends of the support platform. The fixing structures at both ends are connected to the outer shell and the partition, respectively. When the air conditioner 1000 is operating, air will flow in the second chamber. Therefore, the third support member 80, the compressor 300, and the valve island assembly 100 are located in the first chamber to prevent the air from causing the pipes in the first chamber to shake. This improves the stability of the connection between the valve island assembly 100 and the compressor 300 and reduces the possibility of pipe breakage.

[0082] In some embodiments, the connection between the third support member 80 and the housing 200 is detachable. When it is necessary to disassemble the valve island assembly 100, the connection between the third support member 80 and the housing 200 can be detached; and the selection of materials for the third support member 80 and the housing 200, as well as the maintenance and replacement of the third support member 80, are more flexible and convenient.

[0083] In some embodiments, the connection between the third support member 80 and the sixth connecting plate 70 is detachable. When it is necessary to disassemble the valve island assembly 100, the connection between the third support member 80 and the sixth connecting plate 70 can be detached, so that the third support member 80 does not need to be separated from the housing 200, thereby avoiding damage to the structure of the housing 200.

[0084] According to some embodiments of this application, the valve island assembly 100, such as Figure 3 and Figure 15As shown, the plate heat exchanger 11 has plate heat exchanger interfaces 111 connected to the first valve island 12 and plate heat exchanger interfaces 111 not connected to the first valve island 12, which are spaced apart. The valve pipe on the second valve island 20, used for connecting to the first pressure valve 21, is located between the first valve island 12 and the plate heat exchanger interfaces 111 connected to the first valve island 12. For example, in an embodiment including a third valve island 14, a portion of the plate heat exchanger interfaces 111 are connected to the first valve island 12, and another portion are connected to the third valve island 14. The first valve island 12 and the third valve island 14 are spaced apart, and the valve pipe is located between the first valve island 12 and the third valve island 14. As another example, in an embodiment where the plate heat exchanger interfaces 111 and the filter assembly 16 are connected via a connecting pipe 113, and the filter assembly 16 is connected to a second pressure valve 15, the valve pipe on the second valve island 20 used for connecting to the first pressure valve 21 is located between the first valve island 12 and the filter assembly 16.

[0085] Taking an embodiment including the third valve island 14 as an example, it can be understood that the space provided by the first valve island 12 and the third valve island 14, spaced apart, for the valve pipe of the second valve island 20, allows the valve pipe to form a compact spatial combination with the first valve island 12 and the third valve island 14. This avoids the space waste caused by the dispersed arrangement of components, further improves the space utilization of the entire valve island assembly 100, and reduces the overall space occupation of the piping system. The spacing between the first valve island 12 and the third valve island 14 can avoid mutual interference caused by direct contact between components, ensuring the independent and stable operation of the internal flow channels of the first valve island 12 and the third valve island 14. Combined with the integrated fixation of the three valve islands by the support members, the vibration of the two spaced valve islands can be more evenly transmitted and dispersed through the support members under the constraint of the support members, avoiding the superposition of vibrations caused by close contact between components. The valve pipe located in the middle can also reduce its displacement or damage caused by the vibration of the outdoor unit by the overall vibration reduction effect brought by the support members within the space between the two valve islands, indirectly ensuring the stability of fluid transmission and extending the service life of the assembly.

[0086] An air conditioner 1000 according to an embodiment of the present invention includes a valve island assembly 100 according to an embodiment of the present invention. Since the valve island assembly 100 according to an embodiment of the present invention has the aforementioned beneficial technical effects, the air conditioner 1000 according to an embodiment of the present invention, through the first valve island 12 and the second valve island 20, replaces the traditional multi-connection welded pipes, eliminating the need for welding nodes and straight sections and minimum bending radii required for bending, reducing pipe length dependence, improving pipe integration and reducing space occupation; it also reduces the number of welding points, simplifies the pipe system structure, avoids the hidden dangers of complex pipes, and reduces costs due to shorter pipes and simplified structure. Furthermore, the second valve island 20 is detachably connected to the plate heat exchanger assembly 10, allowing the second valve island 20 and the plate heat exchanger assembly 10 to be disassembled separately for component repair and replacement, reducing maintenance costs and operational difficulty.

[0087] An air conditioner 1000 according to a specific embodiment of the present invention will now be described in detail with reference to the accompanying drawings. It is to be understood that the following description is merely illustrative and should not be construed as limiting the present invention.

[0088] like Figures 1-10 As shown, an air conditioner 1000 according to a specific embodiment of the present invention includes a housing 200, a compressor 300, a gas-liquid separator 60, and a valve island assembly 100. The valve island assembly 100 includes a plate heat exchanger assembly 10, a second valve island 20, a first support member 40, a second support member 50, a third support member 80, and a valve plate 30. The plate heat exchanger assembly 10 includes a plate heat exchanger 11, a first valve island 12, a filter assembly 16, a second pressure valve 15, and a throttle valve 92. The upper side of the second valve island 20 is integrated with a first pressure valve 21, a multi-way valve 91, and a throttle valve 92.

[0089] The plate heat exchanger 11 has four plate heat exchanger ports 111 on its upper surface, two of which are equipped with connecting pipes 113. A first valve island 12 is located above the plate heat exchanger 11, and is in surface-to-surface contact with and welded to the plate heat exchanger 11. The flow channel of the first valve island 12 communicates with the plate heat exchanger ports 111 without connecting pipes 113. A filter assembly 16 is welded to the connecting pipes 113 on the plate heat exchanger 11, and a second pressure valve 15 is connected to the filter assembly 16. A gas-liquid separator 60 is located on one side of the plate heat exchanger 11 in the first horizontal direction. A second valve island 20 is located above the plate heat exchanger 11 and communicates with the gas separation pipe body 61 of the gas-liquid separator 60.

[0090] The first support member 40 includes a first connecting plate 41 and a second connecting plate 42. The first connecting plate 41 is located below the plate heat exchanger 11 and connected to the plate heat exchanger 11 by fasteners 90. The second connecting plate 42 is located between the plate heat exchanger 11 and the gas-liquid separator 60 in a first horizontal direction. In the first horizontal direction, a sixth connecting plate 70 is provided on the side of the plate heat exchanger 11 facing away from the gas-liquid separator 60. The sixth connecting plate 70 is connected to the edge of the first connecting plate 41 away from the second connecting plate 42. The third support member 80 is connected to the sixth connecting plate 70 by fasteners 90 passing through along the first horizontal direction.

[0091] The second support member 50 includes a third connecting plate 51 and a fourth connecting plate 52. The third connecting plate 51 is welded to the top cover of the gas-liquid separator 60, and the second valve island 20 is connected to the third connecting plate 51 by fasteners 90 passing through it vertically. The fourth connecting plate 52 is located between the plate heat exchanger 11 and the gas-liquid separator 60, and is arranged vertically with the second connecting plate 52 and integrally formed.

[0092] The plate heat exchanger 11 has a fifth connecting plate 13 on the side away from the gas-liquid separator 60 in the first horizontal direction. The valve plate 30 is connected to the fifth connecting plate 13 by fasteners 90 passing through in the first horizontal direction. The first pressure valve 21 and the second pressure valve 15 are supported in the mounting groove 31 of the valve plate 30 and are connected to the valve plate 30 by fasteners 90 passing through in the first horizontal direction.

[0093] When the second valve island 20 needs to be disassembled separately, the fasteners 90 connecting the second valve island 20 and the third connecting plate 51 can be removed, the fasteners 90 connecting the first pressure valve 21 and the valve plate 30 can be removed, and the pipelines of the second valve island 20 and components such as the gas-liquid separator 60 and the first valve island 12 can be separated, so that the second valve island 20 can be removed separately. When the plate heat exchanger assembly 10 needs to be disassembled separately, the second valve island 20 can be removed first, and then the fasteners 90 connecting the fifth connecting plate 13 and the third support member 80 can be removed, and the fasteners 90 connecting the plate heat exchanger 11 and the first connecting plate 41 can be removed, so that the plate heat exchanger assembly 10 can be removed separately.

[0094] like Figures 11-12 As shown, the air conditioner 1000 according to the second embodiment of the present invention differs from that of the first embodiment in that: the second connecting plate 42 and the fourth connecting plate 52 are stacked along the first horizontal direction and connected by two fasteners 90 passing through the first horizontal direction. These two fasteners 90 are located on both sides of the plate heat exchanger 11 in the second horizontal direction to facilitate disassembly of the fasteners 90 and to prevent interference with the plate heat exchanger 11. The second horizontal direction is perpendicular to the first horizontal direction.

[0095] When it is necessary to disassemble the plate heat exchanger assembly 10 separately, the fasteners 90 connecting the second connecting plate 42 and the fourth connecting plate 52 can be removed without removing the fasteners 90 connecting the first connecting plate 41 and the plate heat exchanger 11. This allows the plate heat exchanger assembly 10 to be moved out from the lower side of the second valve island 20 without disassembling the second valve island 20, thus allowing the plate heat exchanger assembly 10 to be removed separately.

[0096] like Figures 13-20As shown, the air conditioner 1000 according to the third embodiment of this utility model differs from the second embodiment in that: the plate heat exchanger 11 does not have a connecting pipe 113 at the plate heat exchanger interface 111; the plate heat exchanger assembly 10 includes a third valve island 14, which is connected to different plate heat exchanger interfaces 111, and the third valve island 14 is connected to a second pressure valve 15. The plate heat exchanger 11 does not have a fifth connecting plate 13; the two ends of the valve plate 30 are connected to the first valve island 12 and the third valve island 14 respectively by fasteners 90 passing through in the second horizontal direction. The first connecting plate 41 is sandwiched between the plate heat exchanger 11 and the first valve island 12, and between the plate heat exchanger 11 and the third valve island 14, and is welded to the plate heat exchanger 11, the first valve island 12, and the third valve island 14.

[0097] like Figure 21 and Figure 22 As shown, the air conditioner 1000 according to the fourth embodiment of this utility model differs from the second embodiment in that: the plate heat exchanger 11 does not have a connecting pipe 113 at the plate heat exchanger interface 111; the plate heat exchanger assembly 10 includes a third valve island 14, which is connected to different plate heat exchanger interfaces 111, and the third valve island 14 is connected to a second pressure valve 15. The plate heat exchanger 11 does not have a fifth connecting plate 13; the two ends of the valve plate 30 are connected to the first valve island 12 and the third valve island 14 respectively by fasteners 90 passing through in the second horizontal direction.

[0098] Other configurations and operations of the air conditioner 1000 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
