Furthermore, features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] The following reference Figures 1 to 12 The present invention describes a flow path integration module 100 and an air conditioner 1000 according to embodiments of the present invention.

[0027] Combination Figures 1 to 3 According to an embodiment of the present utility model, the flow path integrated module 100 includes: an integrated valve island 10 and a plate heat exchanger 20. The integrated valve island 10 is provided with a plate heat exchanger joint portion 11, and the plate heat exchanger 20 is formed with a mating joint portion 21, which is adapted to be inserted into and sealed with the plate heat exchanger joint portion 11.

[0028] For example, the mating joint 21 and the plate heat exchanger joint 11 can be inserted into each other. For instance, the mating joint 21 can be inserted into the plate heat exchanger joint 11, or the plate heat exchanger joint 11 can be inserted into the mating joint 21. Through the insertion and engagement of the mating joint 21 and the plate heat exchanger joint 11, the plate heat exchanger 20 and the integrated valve island 10 can be connected to each other. This facilitates the positioning and installation of the plate heat exchanger 20 and the integrated valve island 10, improves the assembly convenience of the plate heat exchanger 20, and facilitates the disassembly of the plate heat exchanger 20 and the integrated valve island 10.

[0029] Furthermore, the mating joint 21 and the plate heat exchanger joint 11 are sealed together. For example, sealant can be used to fill the space between the mating joint 21 and the plate heat exchanger joint 11, or a sealing gasket can be provided between the mating surfaces of the mating joint 21 and the plate heat exchanger joint 11 to achieve a seal between the mating joint 21 and the plate heat exchanger joint 11, so as to prevent leakage of the heat exchange medium flowing between the integrated valve island 10 and the plate heat exchanger 20.

[0030] It is understood that the above-mentioned use of sealant or gasket to achieve a sealing fit between the mating joint 21 and the plate heat exchanger joint 11 is only two examples for ease of understanding and should not be construed as a limitation of this application. Other methods can also be used to achieve a sealing fit between the mating joint 21 and the plate heat exchanger joint 11, as long as the sealing effect between the mating joint 21 and the plate heat exchanger joint 11 is guaranteed. No specific limitation is made here.

[0031] In related technologies, plate heat exchangers and integrated valve islands are usually sealed together by welding. However, this method increases the number of weld points in the flow path integrated module, reduces the production and assembly efficiency of the flow path integrated module, and when the materials of the plate heat exchanger and the integrated valve island are different, welding will produce electrochemical corrosion, affecting the reliability of the fit between the plate heat exchanger and the integrated valve island.

[0032] This application facilitates the positioning and installation of the plate heat exchanger 20 and the integrated valve island 10 by inserting and sealing the mating joint 21 with the plate heat exchanger joint 11. It also ensures the sealing between the mating joint 21 and the plate heat exchanger joint 11 without welding, which facilitates the disassembly of the plate heat exchanger 20, prevents leakage between the integrated valve island 10 and the plate heat exchanger 20, and reduces the number of weld points between the plate heat exchanger 20 and the integrated valve island 10. This improves the production and assembly convenience of the flow path integrated module 100 and helps to avoid electrochemical corrosion caused by welding.

[0033] Combination Figures 1 to 5 In some embodiments of this utility model, the flow path integration module 100 further includes a sealing element 30, which is disposed on the mating joint portion 21 and is used to seal the plate heat exchanger portion 11 and the mating joint portion 21.

[0034] For example, the mating joint 21 can be inserted into the plate heat exchanger joint 11, and the seal 30 can be configured as a sealing ring. The outer peripheral wall of the mating joint 21 can be formed with a mounting groove that is recessed in the radial direction away from the plate heat exchanger joint 11. The seal 30 can be embedded in the mounting groove. When the mating joint 21 is inserted into the plate heat exchanger joint 11, the seal 30 can seal between the mating joint 21 and the plate heat exchanger joint 11 in the circumferential direction of the mating joint 21 to prevent the heat exchange medium from leaking from the gap due to the gap between the plate heat exchanger joint 11 and the mating joint 21.

[0035] Combination Figures 4 to 7 In some embodiments of the present invention, the plate heat exchanger 20 includes: a plate heat exchanger body 22 and a connecting plate 23. The connecting plate 23 is disposed on the side of the plate heat exchanger body 22 facing the integrated valve island 10 and is used to connect with the integrated valve island 10. The side of the connecting plate 23 facing the integrated valve island 10 has a mating joint portion 21 that communicates with the plate heat exchanger body 22.

[0036] For example, a medium flow channel for the heat exchange medium is formed inside the plate heat exchanger body 22. A connecting plate 23 is disposed on the side of the plate heat exchanger body 22 facing the integrated valve island 10 so as to connect with the integrated valve island 10. A mating joint 21 is disposed on the side of the connecting plate 23 facing the integrated valve island 10. In the arrangement direction of the connecting plate 23 and the plate heat exchanger body 22, the mating joint 21 can be disposed through the connecting plate 23 so as to communicate with the medium flow channel inside the plate heat exchanger body 22, thereby facilitating the flow of the heat exchange medium between the plate heat exchanger 20 and the integrated valve island 10.

[0037] Therefore, by setting up the connecting plate 23 and connecting the connecting plate 23 to the integrated valve island 10, there is no need to set up a connection point on the plate heat exchanger body 22. This is beneficial to improving the assembly convenience of the plate heat exchanger 20 and the integrated valve island 10, while preventing leakage caused by setting up a connection point on the plate heat exchanger body 22.

[0038] It should be noted that the medium flow channel inside the heat exchanger body 22 can be used as part of the refrigerant circuit of the air conditioner 1000 described below.

[0039] In some embodiments of this utility model, the connecting plate 23 can be integrated with the plate heat exchanger body 22 to simplify the assembly process of the flow path integration module 100 and improve the production and assembly efficiency of the flow path integration module 100. In other embodiments of this utility model, the connecting plate 23 can be separately arranged and connected with the plate heat exchanger body 22 to form an integrated component. For example, the connecting plate 23 and the plate heat exchanger body 22 can be fixedly connected by welding, bonding or snap-fitting to form an integrated component. By making the connecting plate 23 and the plate heat exchanger body 22 separately arranged, it is easier to process the connecting plate 23 and the plate heat exchanger body 22, which is beneficial to improving the production convenience of the plate heat exchanger 20.

[0040] Combination Figure 6 and Figure 7 In some embodiments of this utility model, the connecting plate 23 is connected to the integrated valve island 10 outside the orthographic projection outline of the plate-changing body 22 toward the integrated valve island 10.

[0041] For example, in the first direction, the orthographic projection surface of the plate-mount body 22 is located within the orthographic projection surface of the connecting plate 23, and the orthographic projection outer contour of the connecting plate 23 is spaced apart from the orthographic projection outer contour of the plate-mount body 22. The position where the connecting plate 23 is connected to the integrated valve island 10 is defined as the connection point of the connecting plate 23. The orthographic projection of the connection point is located outside the orthographic projection contour of the plate-mount body 22. That is, in the first direction, the orthographic projection of the connection point is misaligned with the orthographic projection of the plate-mount body 22 to prevent the plate-mount body 22 from interfering with the connection between the connecting plate 23 and the integrated valve island 10, and at the same time, it can prevent the plate-mount body 22 from breaking due to the processing of the connection point.

[0042] It should be noted that "first direction" can be understood as the thickness direction of the integrated valve island 10, or the height direction of the flow path integrated module 100. A specific direction diagram can be found in [reference needed]. Figure 7 and Figure 10 As shown.

[0043] Combination Figures 6 to 9 In some embodiments of this utility model, one of the connecting plate 23 and the integrated valve island 10 is provided with a connecting part 231, and the other of the connecting plate 23 and the integrated valve island 10 may be provided with a connecting mating part 12. The fastener 232 may pass through the connecting part 231 and be connected to the connecting mating part 12.

[0044] In some examples, the connecting plate 23 is provided with a connecting part 231, which is constructed as a screw hole that passes through the connecting plate 23 in a first direction. The integrated valve island 10 is provided with a connecting mating part 12 on the side facing the plate heat exchanger 20. The connecting mating part 12 is constructed as a screw post. The fastener 232 can be configured as a screw, and the fastener 232 can pass through the screw hole and be connected to the screw post, thereby realizing the fixed connection between the plate heat exchanger 20 and the integrated valve island 10.

[0045] In addition, the connection part 231 is provided outside the orthographic projection outline of the connection plate 23 toward the integrated valve island 10 to prevent the plate heat exchanger body 22 from cracking during the processing of the connection part 231, thereby helping to reduce the risk of heat exchange medium leakage from the plate heat exchanger body 22.

[0046] In other examples, the connecting plate 23 is provided with a connecting mating part 12, which is constructed as a screw post. The integrated valve island 10 is provided with a connecting part 231 on the side facing the plate heat exchanger 20. The connecting part 231 can be constructed as a screw hole that passes through the integrated valve island 10 in a first direction. The fastener 232 can be constructed as a screw. The fastener 232 passes through the connecting part 231 provided on the integrated valve island 10 and is connected to the connecting mating part 12 provided on the connecting plate 23, thereby realizing the fixed connection between the plate heat exchanger 20 and the integrated valve island 10.

[0047] It is understood that the above-mentioned positions of the connecting part 231 and the connecting mating part 12, as well as the specific structure of the connecting part 231 and the connecting mating part 12, are merely examples of this application and should not be construed as limitations on this application. The specific positions of the connecting part 231 and the connecting mating part 12, as well as the specific structure of the connecting part 231 and the connecting mating part 12, can be determined according to actual production requirements and are not specifically limited here.

[0048] Combination Figures 7 to 10 In some embodiments of this utility model, the integrated valve island 10 includes: a first raft plate 13, the first raft plate 13 defining a first surface 131 and a second surface 132 formed opposite to each other in a first direction, a plate-connector portion 11 disposed on the first surface 131, and a valve body connector portion 14 disposed on the second surface 132, the valve body connector portion 14 being multiple and used to connect the valve body.

[0049] For example, in the first direction, the side of the first raft plate 13 facing the plate heat exchanger 20 is defined as the first surface 131 of the first raft plate 13, and the side of the first raft plate 13 away from the plate heat exchanger 20 is defined as the second surface 132 of the first raft plate 13. The plate heat exchanger joint portion 11 is provided on the first surface 131 so that the plate heat exchanger joint portion 11 can cooperate with the mating joint portion 21 provided on the plate heat exchanger 20, thereby facilitating the assembly of the plate heat exchanger 20 and the integrated valve island 10.

[0050] Multiple valve body connectors 14 are disposed on the second surface 132. The multiple valve body connectors 14 can be used to connect different valve bodies, such as: four-way valve 70, one-way solenoid valve 102, high-pressure valve 90, low-pressure valve 101, electronic expansion valve 80, etc. During the assembly of the flow path integration module 100, the multiple valve body structural parts can be pre-welded to the corresponding valve bodies. After the pre-assembly welding is completed, the sealing performance of the multiple valve body connectors 14 and the corresponding valve bodies is tested for leaks. In the subsequent final assembly process, the length of the connecting pipes is shorter, which can reduce the number of welding points, thereby reducing the probability of leakage, improving the working stability and reliability of the flow path integration module 100, and also improving the assembly efficiency.

[0051] It is understood that in some embodiments, the integrated valve island 10 includes at least one support plate and a plurality of valve body connectors 14 disposed on the support plate. Through holes can be formed in the support plate, and the valve body connectors 14 can be constructed as flow channel block structures, i.e., the valve body connectors 14 can be constructed as a prism or cylinder structure, and flow channels can be formed inside them, while openings are formed on the end face or side face. These openings can be formed as inlet ends or outlet ends, and the through holes are connected to the inlet ends or outlet ends. A valve body structure can also be correspondingly configured to have one or more inlet ends or one or more outlet ends, so that each flow channel block structure has both an inlet end and an outlet end. This allows the inlet end of the valve body connector 14 to communicate with the corresponding component, and the outlet end to communicate with the corresponding valve body, or the inlet end of an adjacent valve body connector 14 to communicate with the corresponding component. The outlet end is connected to the corresponding valve body, or the adjacent valve body connector 14 is connected, and is connected to different components or different valve bodies respectively, so as to define the series path segment (multiple components, valve bodies, etc. are connected in sequence), parallel path segment (with two or more branches, each branch is equipped with at least one component or valve body), or mixed path segment (including series path segment and mixed path segment) in the refrigerant circuit, and define the valve island structure, such as: the inlet end is connected to the gas-liquid separator 40, oil separator 400 or compressor 300, and the outlet end is connected to the four-way valve 70, electronic expansion valve 80, etc., to form a complete refrigerant circuit, which can reduce the length of the connecting pipes, reduce costs, improve space occupation, reduce the flow resistance and pressure loss of the refrigerant circuit, reduce heat loss, and improve the efficiency of the refrigerant circuit.

[0052] In other embodiments, the integrated valve island 10 may include multiple support plates, and one or more cavities may be formed between adjacent support plates. The cavities may define flow channels, and openings may be provided on the support plates, which communicate with the cavities to achieve communication between adjacent flow channels. Furthermore, the openings on the two outermost support plates in the first direction may be directly formed as valve body connectors 14, or protruding tubes may be further provided on the openings, which form valve body structural parts.

[0053] Of course, it is understood that the integrated valve island 10 may include two or more stacked support plates, with valve body connectors 14 provided between adjacent support plates, and multiple valve body connectors 14 may define multiple flow channels. Any one of the multiple support plates may be formed as a first raft plate 13, such as at least part of the upper plate, middle plate or lower plate of the "valve island" structure being formed as an end cap, or the "valve island" structure may include two or more stacked support plates, with the interlayer cavities of adjacent support plates forming flow channels, located on the two support plates on both sides of the first direction, or with valve body connectors 14 opened on the peripheral edge of the first direction.

[0054] It should be noted that the integrated valve island 10 of this application can be constructed as a "single-layer valve island structure", including one or two support plates, one of which is formed as the first raft plate 13, or it can be constructed as a "multi-layer valve island structure", including three or more support plates, one of which is formed as the first raft plate 13.

[0055] In this way, on the one hand, by setting multiple valve body interface sections on the second surface 132 of the first raft plate 13, multiple valve bodies can be connected to different components through the integrated valve island 10. For example, the flow path integrated module 100 can be applied to the air conditioner 1000. Then, while the integrated valve island 10 is connected to multiple valve bodies, it can also be connected to components such as the compressor 300 and oil separator 400 of the air conditioner 1000 to form a complete refrigerant circuit of the air conditioner 1000. This can reduce the total length of the connecting pipes and the number of solder joints, which can not only reduce the occurrence of refrigerant circuits. The probability of leakage is reduced, improving the safety and reliability of the air conditioner 1000. It can also reduce flow resistance and pressure loss, reduce heat loss in the refrigerant circuit, and improve the efficiency of the air conditioner 1000. On the other hand, by setting the plate heat exchanger joint 11 on the first surface 131, the integrated valve island 10 and the plate heat exchanger 20 can be integrated. The plate heat exchanger body 22 and the integrated valve island 10 are fixed by the connecting plate 23, which facilitates the disassembly and assembly of the plate heat exchanger 20 and the integrated valve island 10. In addition, it can also improve the space occupation of the flow path integrated module 100 and reduce the difficulty of layout.

[0056] Combination Figures 10 to 12 In some embodiments of this utility model, the flow path integrated module 100 further includes a gas-liquid separator 40, the first end of which is disposed on the integrated valve island 10 in the first direction.

[0057] For example, one end of the gas-liquid separator 40 in the first direction can be connected to the first raft plate 13 so that the gas-liquid separator 40 can support the first raft plate 13, thereby solving the installation problem of the first raft plate 13. There is no need to set up an additional installation structure for fixing the first raft plate 13, which helps to simplify the assembly steps of the flow path integration module 100 and improve the production and assembly efficiency of the flow path integration module 100.

[0058] Combination Figures 10 to 12 In some embodiments of this utility model, the flow path integration module 100 further includes a mounting bracket 50, which is connected to the end of the gas-liquid separator 40 away from the integrated valve island 10.

[0059] For example, in the first direction, one end of the flow path integration module 100 is provided with an integrated valve island 10, and the other end of the flow path integration module 100 is connected to a mounting bracket 50. The mounting bracket 50 can be used to support and fix the gas-liquid separator 40. For example, the flow path integration module 100 can be applied to an air conditioner 1000. In the scenario where the flow path integration module 100 is applied to an air conditioner 1000, the mounting bracket 50 can be connected to the housing of the air conditioner 1000 so that the gas-liquid separator 40 can be positioned and installed with the housing through the mounting bracket 50, which is beneficial to improving the assembly reliability of the gas-liquid separator 40.

[0060] Combination Figures 10 to 12 In some embodiments of this utility model, the mounting bracket 50 is formed with a clearance channel 51, which is used to avoid pipeline structures.

[0061] For example, the mounting bracket 50 includes a first plate 52 and a second plate 53. The second plate 53 extends along a first direction and one end of the second plate 53 is connected to the gas-liquid separator 40. The first plate 52 is connected to the end of the second plate 53 away from the gas-liquid separator 40 and is spaced apart from the end of the first plate 52 connected to the gas-liquid separator 40 in the first direction, so that the mounting bracket 50 defines a clearance channel 51 for the passage of pipeline structures.

[0062] Taking the flow path integration module 100 applied to the air conditioner 1000 as an example, the first plate 52 can be connected to the housing of the air conditioner 1000 so that the gas-liquid separator 40 can be positioned and installed with the housing through the mounting bracket 50. Considering that the air conditioner 1000 has a pipeline structure, for example, the air conditioner 1000 can be an outdoor unit of the air conditioner, and the housing has a pipeline structure for connecting with the indoor unit of the air conditioner, in order to facilitate the arrangement of the pipeline structure, the mounting bracket 50 is limited to form an avoidance channel 51 so that the mounting bracket 50 can avoid the pipeline structure through the avoidance channel 51, preventing the pipeline structure from needing to be arranged around because the mounting bracket 50 is located on the route of the pipeline structure. This is beneficial to improving the convenience of arranging the pipeline structure and also to improving the regularity of the housing.

[0063] Combination Figures 10 to 12 In some embodiments of this utility model, the flow path integrated module 100 further includes a support plate 60, which includes a fixed part 61 and a support part 62 connected together. The fixed part 61 is sandwiched between the integrated valve island 10 and the gas-liquid separator 40, and the support part 62 is supported on the side of the plate heat exchanger 20 away from the integrated valve island 10.

[0064] For example, the fixing part 61 and the supporting part 62 are spaced apart in the first direction. The fixing part 61 is sandwiched between the integrated valve island 10 and the gas-liquid separator 40. The fixing part 61 can be connected to the integrated valve island 10 and the gas-liquid separator 40 respectively to improve the connection reliability between the gas-liquid separator 40 and the integrated valve island 10.

[0065] The support portion 62 is located on the side of the fixing portion 61 away from the integrated valve island 10 in the first direction. In the first direction, the support portion 62 can support the plate heat exchanger 20 on the side surface away from the integrated valve island 10. Since the fixing portion 61 is connected to the integrated valve island 10 and the gas-liquid separator 40 respectively, by having the support portion 62 connected to the fixing portion 61 support the plate heat exchanger 20, it is beneficial to improve the assembly reliability of the plate heat exchanger 20.

[0066] Combination Figures 9 to 12 In some embodiments of this utility model, the gas-liquid separator 40 is provided with an inlet pipe 44 and an outlet pipe 43 at one end facing the integrated valve island 10. The second surface 132 has a first region 1321 located within the orthographic projection outline of the gas-liquid separator 40 and a second region 1322 located outside the first region 1321. The inlet pipe 44 is located in the first region 1321 and passes through the first raft plate 13 in the direction from the first surface 131 to the second surface 132. The outlet pipe 43 is located outside the integrated valve island 10.

[0067] For example, the first raft plate 13 is provided with a perforation 133, through which the inlet pipe 44 can pass through the perforation 133 into the flow path structure, and the end of the inlet pipe 44 away from the gas-liquid separator 40 can be set toward the four-way valve 70 so that the inlet pipe 44 can be connected to the four-way valve 70. At the same time, the opening of the valve body connector 14 on the integrated valve island 10 for connecting to the four-way valve 70 is also set toward the four-way valve 70 so that the integrated valve island 10 can be connected to the four-way valve 70.

[0068] By providing a perforation 133, when the inlet pipe 44 passes through the integrated valve island 10, the integrated valve island 10 can avoid the inlet pipe 44, facilitating direct connection between the inlet pipe 44 and the four-way valve 70. The vibration transmitted by the compressor 300 through the four-way valve 70 can be partially dispersed by the gas-liquid separator 40, thereby reducing the vibration transmitted to the integrated valve island 10 to a certain extent, improving the reliability of the integrated valve island 10. Furthermore, since no additional connecting pipeline is required, it is beneficial to reduce the number of solder joints in the flow path integrated module 100, improving the reliability and stability of the flow path integrated module 100. At the same time, it is beneficial to improve the space utilization rate on the integrated valve island 10. In other words, the inlet pipe 44 does not need to occupy the space on the outer periphery of the integrated valve island 10, which is beneficial to improve the integration degree between the gas-liquid separator 40 and the integrated valve island 10, and reduce the space occupied by the flow path integrated module 100.

[0069] Considering the limited space on the integrated valve island 10, the outlet pipe 43 can be set outside the integrated valve island 10 to avoid increasing the volume of the integrated valve island 10 due to the need to design the arrangement space of the outlet pipe 43 on the integrated valve island 10. At the same time, it is beneficial to simplify the processing of the integrated valve island 10 and improve the production efficiency of the integrated valve island 10.

[0070] Combination Figures 9 to 12 In some embodiments of this utility model, in the first direction, the orthographic projection surface of the plate heat exchanger 11 is located within the orthographic projection range of the second region 1322 and is spaced apart from the gas-liquid separator 40.

[0071] For example, after the gas-liquid separator 40 is assembled with the integrated valve island 10, in the first direction, the portion of the second surface 132 opposite to the orthographic projection surface of the gas-liquid separator 40 is defined as the first region 1321, and the portion of the second surface 132 excluding the portion opposite to the orthographic projection surface of the gas-liquid separator 40 is defined as the second region 1322. The plate heat exchanger 11 is disposed on the first surface 131, and the orthographic projection surface of the plate heat exchanger 11 is located within the orthographic projection range of the second region 1322, so that the plate heat exchanger 11 can be spaced apart from the gas-liquid separator 40, thereby facilitating the spaced arrangement of the plate heat exchanger 20 and the gas-liquid separator 40, and preventing the plate heat exchanger 20 and the gas-liquid separator 40 from being unable to be assembled with the integrated valve island 10 due to mutual interference between them.

[0072] Combination Figures 9 to 12 In some embodiments of this utility model, the valve body connector 14 further includes a four-way valve connector 143, which is located in the first region 1321 and is used to connect the four-way valve 70.

[0073] Specifically, the surface area of ​​the first region 1321 is larger than the area of ​​the perforation 133, so that the first region 1321 forms a gap region except for the location where the perforation 133 is provided, and the corresponding four-way valve connector 143 can be formed in the gap region.

[0074] In this way, at least the four-way valve connector 143 and the through hole 133 can be located in the first region 1321, so as to make full use of the space in the first region 1321, realize the compact arrangement of the integrated valve island 10, further reduce the space occupied by the integrated valve island 10, and reduce the difficulty of arranging the integrated valve island 10.

[0075] It is understood that the structure of the embodiments of this application is not limited to this. Other connectors of the valve body connector 14, except for the four-way valve connector 143, can also be integrated into the first region 1321. The design can be made reasonably according to the layout requirements.

[0076] Combination Figures 10 to 12 In some embodiments of this utility model, the valve body connector 14 further includes at least one expansion valve connector 144, a high-pressure valve connector 145, and a low-pressure valve connector 146. The expansion valve connector 144, the low-pressure valve connector 146, and the high-pressure valve connector 145 are all located in the second region 1322 and are respectively used to connect the electronic expansion valve 80, the high-pressure valve 90, and the low-pressure valve 101.

[0077] Taking the application of the flow path integration module 100 to the air conditioner 1000 as an example, when the air conditioner 1000 has an enthalpy-increasing branch, at least two electronic expansion valves 80 need to be installed in the refrigerant circuit, and the corresponding valve body connector 14 includes at least two expansion valve connectors 144. When the air conditioner 1000 does not have an enthalpy-increasing branch, at least one electronic expansion valve 80 needs to be installed in the refrigerant circuit, and the corresponding valve body structure should include at least one expansion valve connector 144.

[0078] Combination Figures 7 to 9 In some embodiments of this utility model, the integrated valve island 10 further includes a second raft plate 15, which is connected to the first raft plate 13 and is used to fix the high-pressure valve 90 and the low-pressure valve 101.

[0079] Therefore, the high-pressure valve 90 and the low-pressure valve 101 are fixed by the second raft plate 15, and the second raft plate 15 is connected to the first raft plate 13, so that the high-pressure valve 90 and the low-pressure valve 101 can be supported by the gas-liquid separator 40 through the integrated valve island 10, without the need for a further connection structure between the low-pressure valve 101 and the high-pressure valve 90 and the housing. This also reduces the number of structural components, lowers the layout difficulty, and improves space occupancy. At the same time, the high-pressure valve 90 and the low-pressure valve 101 do not need to be connected to the housing separately by structural components, which also avoids the connecting pipeline of the low-pressure valve 101 and the high-pressure valve 90 from becoming a noise radiation transmission path of the compressor 300, further improving the working noise.

[0080] like Figure 10 As shown, the air conditioner 1000 according to an embodiment of the present utility model includes a housing and the flow path integration module 100 in the above embodiment. The flow path integration module 100 is disposed inside the housing and is connected to the housing through a mounting bracket 50.

[0081] According to the embodiment of the utility model, the air conditioner 1000 adopts the above-mentioned flow path integrated module 100, which allows the mating joint 21 to be inserted and sealed with the plate heat exchanger joint 11, facilitating the positioning and installation between the plate heat exchanger 20 and the integrated valve island 10. Furthermore, it ensures the sealing between the mating joint 21 and the plate heat exchanger joint 11 without welding, facilitating the disassembly of the plate heat exchanger 20 while preventing leakage between the integrated valve island 10 and the plate heat exchanger 20. It also reduces the number of weld points between the plate heat exchanger 20 and the integrated valve island 10, which is beneficial to improving the production and assembly convenience of the flow path integrated module 100 and helps to avoid electrochemical corrosion caused by welding.

[0082] Combination Figures 10 to 12 In some embodiments of this utility model, the housing includes a chassis assembly 200 disposed at the bottom in a first direction, the compressor 300 of the air conditioner 1000 is positioned and mounted on the chassis assembly 200, and the gas-liquid separator 40 is fixedly connected to the chassis assembly 200 through a mounting bracket 50 to improve the assembly reliability of the gas-liquid separator 40.

[0083] The specific flow path of the refrigerant circuit in this embodiment is as follows: The four-way valve has a first interface, a second interface, a third interface and a fourth interface, and the plate heat exchanger has a first side inlet end, a first side outlet end, a second side inlet end and a second side outlet end.

[0084] The refrigerant discharged from the compressor passes through the oil separator and then enters the first port through the connecting pipe. After passing through the second port, it enters the low-pressure valve connector and then the low-pressure valve, entering the evaporator (i.e., the indoor heat exchanger). After exchanging heat with the environment, the refrigerant enters the high-pressure valve through the high-pressure valve connector. After flowing through the high-pressure valve, it enters the first side inlet. After flowing out from the first side outlet, the refrigerant is divided into two paths. One path flows through the enthalpy-increasing branch. In the enthalpy-increasing branch, the refrigerant is further throttled by an electronic expansion valve before entering the second side inlet. After sufficient heat exchange in the plate heat exchanger, the refrigerant enters the compressor enthalpy-increasing port through the connecting pipe from the second side outlet. Another refrigerant path passes through another electronic expansion valve and enters the condenser (i.e., the outdoor heat exchanger). After exchanging heat with the outdoor environment, the refrigerant enters the third port and then enters the inlet pipe through the fourth port. It undergoes gas-liquid separation in the gas-liquid separator and then enters the compressor return port through the outlet pipe and connecting pipeline to complete one refrigerant cycle in the refrigerant circuit.
