[0076] The embodiments of this utility model 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 utility model, and should not be construed as limiting this utility model.

[0077] In the description of this utility model, it should be understood that the terms "length," "width," "thickness," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined as "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.

[0078] 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.

[0079] The following is for reference. Figures 1-17 The present invention describes a flow path integration module 100 and an air conditioning system 1000 according to embodiments of the present invention.

[0080] like Figure 1 As shown, the flow path integration module 100 according to an embodiment of the present utility model is used in an air conditioning system 1000, and the flow path integration module 100 includes: a substrate 10 and a flow path module 20, the flow path module 20 being disposed on the thickness side of the substrate 10.

[0081] For example, the substrate 10 can serve as a mounting carrier for the flow path module 20, facilitating the positioning and installation of the flow path module 20. This improves the installation convenience of the flow path integrated module 100. For instance, the flow path module 20 can be pre-installed on the substrate 10. After the flow path module 20 and the substrate 10 are assembled to form the flow path integrated module 100, the flow path integrated module 100 can be positioned and installed through the substrate 10. There is no need to position and assemble the substrate 10 and the flow path module 20 separately, thus improving the installation convenience of the flow path integrated module 100.

[0082] Combination Figures 2 to 4 as well as Figure 7 and Figure 8 The flow path module 20 includes flow channel components 21. There are multiple flow channel components 21 and they are spaced apart. Each flow channel component 21 has a first flow channel 211 and the first flow channel 211 has at least two interfaces 212.

[0083] Each first flow channel 211 can be connected to different components of the air conditioning system 1000. For example, the air conditioning system 1000 may include components such as a compressor 201, valves, and heat exchangers. The refrigerant can circulate in the air conditioning system 1000. One of the multiple first flow channels 211 can be connected to the valves and the heat exchangers respectively. For example, one interface 212 of the first flow channel 211 can be connected to the valves, and another interface 212 of the first flow channel 211 can be connected to the heat exchangers. This allows different components of the air conditioning system 1000 to be connected through the flow path module 20, so that the refrigerant can circulate in the air conditioning system 1000. Thus, by setting up the flow path integration module 100, it is beneficial to eliminate the need for corresponding piping for different components of the air conditioning system 1000, simplify the piping setup of the air conditioning system 1000, reduce the production and processing costs of the air conditioning system 1000, and improve the production and assembly efficiency of the air conditioning system 1000. At the same time, it is beneficial to reduce the volume of the air conditioning system 1000, thereby reducing the layout space required for the air conditioning system 1000.

[0084] Combination Figures 1 to 4 as well as Figure 7 The flow path module 20 also includes a connector 22, which is connected between two adjacent flow path components 21, and the connector 22 is set to avoid the interface 212.

[0085] For example, two adjacent flow channels 21 are connected by a connector 22, and the connector 22 is arranged to avoid obstructing the interface 212, so as to ensure the connectivity of the first flow channel 211.

[0086] By connecting the connector 22 between two adjacent flow channel components 21, multiple flow channel components 21 can be connected, which facilitates the modular assembly of the flow path module 20 and helps to improve the strength of the flow channel components 21. Specifically, the connector 22 can support the flow channel components 21, thereby improving the structural strength of the flow channel components 21, and also helps to improve the integration of the flow path module 20, reduce the assembly difficulty of the flow path module 20, and improve the assembly efficiency of the flow path module 20. This, in turn, helps to improve the integration of the flow path integrated module 100, reduce the assembly difficulty of the flow path integrated module 100, and improve the production efficiency of the flow path integrated module 100.

[0087] Combination Figures 1 to 4 as well as Figure 7 The connector 22 is spaced apart from the substrate 10.

[0088] For example, in the thickness direction of the substrate 10, the side of the connector 22 facing the substrate 10 is spaced apart from the substrate 10. It can also be understood that the connector 22 and the substrate 10 are not coplanar, and there is no need to connect the connector 22 to the substrate 10, which helps to reduce the processing difficulty and processing cost of the flow path integration module 100.

[0089] Considering that the refrigerant temperatures in the two first flow channels 211 connected by the same connector 22 may be different, the refrigerant in the two first flow channels 211 connected by the same connector 22 may exchange heat through the connector 22. By setting the connector 22 and the substrate 10 at intervals, an air gap is created between the connector 22 and the substrate 10, which helps to increase the contact area between the connector 22, the substrate 10 and the air, thereby facilitating heat dissipation on the connector 22 and reducing heat exchange between the two first flow channels 211 connected to the same connector 22, thus helping to ensure the performance of the air conditioning system 1000.

[0090] In related technologies, the connecting bridge of the integrated module is usually welded to the base plate. This means that the flatness requirements of the connecting bridge and the base plate are high, which leads to high processing accuracy requirements for the integrated module and affects the processing convenience of the integrated module. Furthermore, due to the small contact area between the connecting bridge and the air, the heat dissipation area of ​​the connecting bridge is small, which makes it easy for heat exchange to occur between the two flow channels connected to the connecting bridge, affecting the working performance of the air conditioning system.

[0091] This application provides a connector 22 so that multiple flow channel components 21 can be connected to form a flow path module 20, thereby improving the integration of the flow path module 20 and reducing the assembly difficulty of the flow path module 20. By further spacing the connector 22 from the substrate 10, it is not necessary to connect the connector 22 to the substrate 10, which helps to reduce the processing difficulty and processing cost of the flow path integrated module 100. In addition, an air gap can be created between the connector 22 and the substrate 10, thereby increasing the contact area between the connector 22, the substrate 10 and the air, thus increasing the heat dissipation area of ​​the connector 22. This helps to reduce the heat exchange between the two first flow channels 211 connected to the same connector 22 through the connector 22, thereby reducing the impact of the connector 22 on the working performance of the air conditioning system 1000.

[0092] In some embodiments, the flow path module 20 is welded to the substrate 10 to improve the sealing performance of the first flow channel 211, and at the same time, it helps to improve the connection strength between the flow path module 20 and the substrate 10, thereby helping to improve the structural strength of the flow path integrated module 100.

[0093] By spacing the connector 22 from the substrate 10, the connector 22 does not need to be welded to the substrate 10. This reduces the flatness requirements of the connector 22 and the substrate 10, thereby reducing the processing accuracy requirements of the flow path integration module 100. This, in turn, helps to improve the production efficiency of the flow path integration module 100 and reduces welding costs, thus reducing the production cost of the flow path integration module 100.

[0094] Combination Figure 1 , Figure 2 as well as Figure 13 In some embodiments of this utility model, the orthographic projections of multiple flow channel components 21 on the substrate 10 are spaced apart; and / or, the orthographic projection of the flow path module 20 on the substrate 10 is located within the outer contour of the substrate 10.

[0095] In some examples, the orthographic projections of multiple flow channel components 21 are spaced apart on the substrate 10. That is, the multiple flow channel components 21 do not overlap in the thickness direction of the substrate 10. It can also be understood that the multiple flow channel components 21 are respectively laid on the substrate 10, so as to facilitate the arrangement of multiple flow channel components 21 on the substrate 10. This is beneficial to improve the assembly convenience of multiple flow channel components 21, so as to achieve reasonable allocation of space on the substrate 10, while reducing the size of the flow path module 20 in the thickness direction of the substrate 10. This is beneficial to reduce the size of the flow path integration module 100 in the thickness direction of the substrate 10, and further beneficial to reduce the size of the air conditioning system 1000, realize the miniaturization design of the air conditioning system 1000, and improve the assembly convenience of the air conditioning system 1000.

[0096] In other examples, the orthographic projection of the flow path module 20 on the substrate 10 is located within the outer contour of the substrate 10. This can also be understood as the flow path module 20 being disposed on the substrate 10, and the orthographic projection area of ​​the flow path module 20 being smaller than the area of ​​the substrate 10, so as to ensure the support effect of the substrate 10 on the flow path module 20, improve the assembly convenience of the flow path module 20, and help improve the stability of the flow path module 20.

[0097] It is understandable that as long as the orthographic projection of the flow path module 20 on the substrate 10 is within the outer contour of the substrate 10, the specific shape of the substrate 10 can be determined according to the actual production requirements. For example, the substrate 10 can be constructed as a square plate, or the shape of the substrate 10 can be roughly adapted to the overall outer contour of the flow path module 20 to improve the processing convenience of the substrate 10.

[0098] In some other examples, the orthographic projections of multiple flow channel components 21 are spaced apart on the substrate 10, while the orthographic projection of the flow path module 20 on the substrate 10 is located within the outer contour of the substrate 10. That is, multiple flow channel components 21 are laid on the substrate 10, and the orthographic projection area of ​​the flow path module 20 is smaller than the area of ​​the substrate 10, so as to achieve reasonable allocation of space on the substrate 10, reduce the size of the flow path module 20 in the thickness direction of the substrate 10, and further improve the assembly convenience and assembly stability of the flow path module 20.

[0099] Combination Figures 2 to 4 as well as Figure 7 In some embodiments of this utility model, at least one of two adjacent flow channel components 21 has a side surface away from the substrate 10 that is coplanar with the side surface away from the substrate 10 of the corresponding connector 22; and / or, there are multiple connectors 22, and at least two connectors 22 have a side surface away from the substrate 10 that is coplanar.

[0100] In some examples, the side surface of at least one of two adjacent flow channel components 21 facing away from the substrate 10 is coplanar with the side surface of the corresponding connector 22 facing away from the substrate 10. For example, the side surface of one of the two adjacent flow channel components 21 facing away from the substrate 10 and the side surface of the corresponding connector 22 (or the connector 22 connected to it) facing away from the substrate 10 are on the same plane; or the side surface of the two adjacent flow channel components 21 facing away from the substrate 10 and the side surface of the corresponding connector 22 (or the connector 22 connected to them) facing away from the substrate 10 are on the same plane, which is beneficial to improving the processing convenience of the flow path module 20. Specifically, when processing the flow channel components 21 and the connector 22, the number of preset height dimensions to be processed can be reduced, thereby improving the processing convenience of the flow path module 20 and thus improving the production efficiency of the flow path module 20.

[0101] It should be noted that the above "height dimension" can be understood as the distance between the side of the flow channel component 21 and the connector 22 facing away from the substrate 10 and the substrate 10.

[0102] In other examples, at least two of the connectors 22 have coplanar surfaces on the side facing away from the substrate 10. For example, there may be four connectors 22, with two of the four connectors 22 having coplanar surfaces on the side facing away from the substrate 10, or three of the four connectors 22 having coplanar surfaces on the side facing away from the substrate 10, or all four connectors 22 having coplanar surfaces on the side facing away from the substrate 10. This reduces the height of the connectors 22 that need to be processed, which is beneficial to improving the processing convenience of the flow path module 20 and thus improving the production efficiency of the flow path module 20.

[0103] In some other examples, the side surface of at least one of two adjacent flow channel components 21 facing away from the substrate 10 is coplanar with the side surface of the corresponding connector 22 facing away from the substrate 10; there are multiple connectors 22, and the side surfaces of at least two connectors 22 facing away from the substrate 10 are coplanar. For example, the side surfaces of multiple flow channel components 21 facing away from the substrate 10 and the side surfaces of multiple connectors 22 facing away from the substrate 10 are all coplanar, so that only one height dimension needs to be set when processing the flow channel components 21 and the connectors 22, so as to further improve the processing convenience of the flow path module 20, thereby helping to improve the production and processing efficiency of the flow path module 20.

[0104] Combination Figure 1 , Figure 7 , Figure 9 and Figure 10 In some embodiments of this utility model, each flow channel component 21 corresponds to at least one connector 22, and a positioning protrusion 11 is provided on the thickness side of the substrate 10, the positioning protrusion 11 abuts against the outer surface of the corresponding flow channel component 21.

[0105] It should be noted that the "outer surface of the flow channel component 21" can be understood as the side surface of the multiple flow channel components 21 that is opposite to each other, or it can be understood as the side surface of the flow channel component 21 that is away from the center of the flow path module 20.

[0106] For example, any two adjacent flow channel components 21 in the plurality of flow channel components 21 are connected by a connector 22. For instance, the flow path module 20 may include three flow channel components 21 arranged in a straight line. Then, the flow channel components 21 located on both sides can be connected to the flow channel component 21 located in the middle position by a connector 22. The flow path module 20 may include a plurality of flow channel components 21 arranged in a circle. Then, any two adjacent flow channel components 21 can be connected by a connector 22. The connector 22 is set to avoid obstructing the interface 212 to prevent the connector 22 from blocking the interface 212 and to ensure the connectivity of the first flow channel 211.

[0107] It is understood that the quantity and arrangement of the above-mentioned flow channel components 21 are examples for the purpose of explanation and understanding, and should not be construed as limitations on this application. The quantity and arrangement of the flow channel components 21 can be determined according to actual production requirements, and no specific limitations are made here.

[0108] The substrate 10 has a positioning protrusion 11 on the side surface facing the flow path module 20 in the thickness direction. The positioning protrusion 11 protrudes in the direction away from the substrate 10. The positioning protrusion 11 can be abutted and engaged with the outer surface of the flow channel component 21 so that the flow path module 20 can be positioned and installed on the substrate 10 through the positioning protrusion 11, which is beneficial to improving the assembly convenience of the flow path module 20.

[0109] Combination Figure 1 , Figure 7 , Figure 9 and Figure 10 In some embodiments of this utility model, there are multiple positioning protrusions 11, including a first positioning protrusion 111 and a second positioning protrusion 112. The first positioning protrusion 111 and the second positioning protrusion 112 are spaced apart along a direction perpendicular to the thickness direction of the substrate 10, and their opposite sides are respectively recessed in a direction away from each other. The flow path module 100 abuts between the first positioning protrusion 111 and the second positioning protrusion 112.

[0110] It should be noted that "the direction perpendicular to the thickness direction of the substrate 10" can be the length direction or the width direction of the substrate 10.

[0111] For example, the first positioning protrusion 111 and the second positioning protrusion 112 may be spaced apart along the length direction of the substrate 10, or the first positioning protrusion 111 and the second positioning protrusion 112 may be spaced apart along the width direction of the substrate 10. The side of the first positioning protrusion 111 opposite to the second positioning protrusion 112 is recessed in a direction away from the second positioning protrusion 112. Correspondingly, the side of the second positioning protrusion 112 opposite to the first positioning protrusion 111 is recessed in a direction away from the first positioning protrusion 111. At least part of the flow path module 20... The flow path module 20 can be embedded between the recess formed by the first positioning protrusion 111 and the recess formed by the second positioning protrusion 112. The flow path module 20 can be abutted and engaged with the first positioning protrusion 111 and the second positioning protrusion 112 respectively. The first positioning protrusion 111 and the second positioning protrusion 112 can limit the flow path module 20 in the direction perpendicular to its recess and in the direction perpendicular to the thickness of the substrate 10, thereby realizing the positioning and installation of the flow path module 20 and the substrate 10, and improving the positioning reliability of the flow path module 20 and the substrate 10.

[0112] In some examples, the first positioning protrusion 111 and the second positioning protrusion 112 may be arranged opposite to each other and spaced apart in the direction perpendicular to the thickness of the substrate 10. For example, the first positioning protrusion 111 and the second positioning protrusion 112 may be arranged opposite to each other and spaced apart in the width direction of the substrate 10. One of the multiple flow channel members 21 of the flow path module 20 may respectively abut against the first positioning protrusion 111 and the second positioning protrusion 112 to realize the positioning and installation of the flow path module 20 and the substrate 10.

[0113] In other examples, the first positioning protrusion 111 and the second positioning protrusion 112 may be staggered and spaced apart in a direction perpendicular to the basic thickness. For example, the first positioning protrusion 111 and the second positioning protrusion 112 may be spaced apart in the width direction of the substrate 10, and the first positioning protrusion 111 and the second positioning protrusion 112 may be staggered in the length direction of the substrate 10. One of the multiple flow channel members 21 of the flow path module 20 may abut against the first positioning protrusion 111, and another flow channel member 21 of the multiple flow channel members 21 may abut against the second positioning protrusion 112 to achieve positioning and installation of the flow path module 20 and the substrate 10.

[0114] It is understandable that the specific arrangement of the first positioning protrusion 111 and the second positioning protrusion 112 can be determined according to actual production requirements, and no specific limitation is made here.

[0115] Combination Figures 1 to 4 as well as Figures 9 to 11In some embodiments of this utility model, the side surface of each flow channel component 21 facing the substrate 10 is fixed to the substrate 10, and the side surfaces of multiple flow channel components 21 facing the substrate 10 are coplanar, and the side surface of the substrate 10 facing the flow path module 20 is a plane; and / or, the substrate 10 is a flat plate, and the thickness of the substrate 10 is greater than or equal to 2 mm.

[0116] Combination Figures 1 to 4 In some examples, the side surface of each flow channel component 21 facing the substrate 10 is fixed to the substrate 10, and the side surfaces of multiple flow channel components 21 facing the substrate 10 are coplanar. The side surface of the substrate 10 facing the flow path module 20 is flat. By making the side surfaces of multiple flow channel components 21 facing the substrate 10 coplanar and constructing the side surface of the substrate 10 facing the flow path module 20 as flat, it is convenient to weld the flow channel component 21 to the substrate 10. It is also beneficial to ensure the sealing effect of the substrate 10 on the first flow channel 211 formed by the flow channel component 21 and reduce the risk of refrigerant leakage between the substrate 10 and the flow channel component 21.

[0117] Combination Figures 9 to 11 In other examples, the substrate 10 is constructed as a flat plate to facilitate the processing and assembly of the substrate 10, and the thickness of the substrate 10 is greater than or equal to 2 mm to improve the structural strength of the substrate 10, improve the support effect of the substrate 10 on the flow path module 20, and reduce the risk of damage to the substrate 10, thereby helping to improve the service life of the flow path integration module 100. In addition, since the structural strength of the substrate 10 is improved, the number of flow channel components 21 provided on the substrate 10 can be increased, so that more flow channel components 21 can be provided on the substrate 10 to further improve the integration of the flow path integration module 100.

[0118] It is understood that the thickness of the substrate 10 can be 2mm, 2.5mm, 2.6mm, 3mm, etc. The specific thickness of the substrate 10 can be determined according to actual production requirements, and no specific limit is made here.

[0119] In some other examples, the side surface of each flow channel component 21 facing the substrate 10 is fixed to the substrate 10, and the side surfaces of multiple flow channel components 21 facing the substrate 10 are coplanar. The side surface of the substrate 10 facing the flow path module 20 is flat, and the substrate 10 is constructed as a flat plate with a thickness greater than or equal to 2 mm. This improves the processing convenience of the substrate 10, facilitates the connection of the flow channel component 21 to the substrate 10, ensures the sealing effect of the substrate 10 on the first flow channel 211 formed by the flow channel component 21, improves the structural strength of the substrate 10, enhances the support effect of the substrate 10 on the flow path module 20, reduces the risk of damage to the substrate 10, and thus helps to improve the service life of the flow path integrated module 100.

[0120] Combination Figure 1 and Figure 7 In some embodiments of this utility model, the flow path integration module 100 further includes a welding ring 23. The welding ring 23 is integrally connected to the interface 212 corresponding to the back substrate 10 and protrudes from the side surface of the corresponding flow channel component 21 opposite to the substrate 10 in the direction away from the substrate 10. The welding ring 23 is suitable for insertion and welding with the corresponding pipeline, and the axial height of the welding ring 23 is greater than or equal to 5mm.

[0121] It should be noted that "axial height of welding ring 23" can be understood as the dimension of welding ring 23 in the thickness direction of substrate 10.

[0122] For example, at least one of the interfaces 212 of the first flow channel 211 is located on the side of the flow channel component 21 away from the substrate 10. The interface 212 located on the side of the flow channel component 21 away from the substrate 10 can be connected to the components of the air conditioning system 1000 through the transition tube 230. The transition tube 230 can be inserted and welded to the welding ring 23 at the corresponding interface 212. By making the axial height of the welding ring 23 greater than or equal to 5mm, it is easier for the transition tube 230 and the welding ring 23 to be inserted and engaged, and it is beneficial to increase the contact area between the welding ring 23 and the transition tube 230, thereby improving the connection reliability between the welding ring 23 and the transition tube 230.

[0123] In other embodiments, the welding ring 23 can be separately disposed from the flow channel component 21, and the welding ring 23 can be fixedly installed at the interface 212 provided on the corresponding back substrate 10 by means of welding or other connection methods.

[0124] In a further embodiment of this utility model, the axial height of the welding ring 23 is greater than or equal to 5 mm and less than or equal to 15 mm. By designing the axial height of the welding ring 23, it is beneficial to improve the reliability of the fit between the welding ring 23 and the corresponding pipeline, and at the same time, it is beneficial to reduce the material used for the welding ring 23, thereby reducing the production and processing cost of the flow path integration module 100.

[0125] When the axial height of the welding ring 23 is less than 5mm, the axial height of the welding ring 23 is too small, resulting in poor insertion reliability between the transition tube 230 and the welding ring 23. It also leads to a small contact area between the transition tube 230 and the welding ring 23, thereby affecting the connection strength between the transition tube 230 and the welding ring 23. When the axial height of the welding ring 23 is greater than 15mm, the axial height of the welding ring 23 is too large, resulting in excessive material usage for the welding ring 23 and increasing the material cost of the flow path module 20.

[0126] Combination Figure 1 and Figure 7In some embodiments of this utility model, the multiple interfaces 212 of the flow path module 20 include a first interface and a second interface. The first interface is disposed along the second direction toward the outer edge of the substrate 10 and is adapted to be connected to the low-pressure valve 203 or the high-pressure valve 204 of the air conditioning system 1000. The second interface is disposed away from the substrate 10.

[0127] It should be noted that "first direction" can be understood as the length direction of the substrate 10 mentioned above, and "second direction" can be understood as the width direction of the substrate 10. For a specific direction diagram, please refer to [reference needed]. Figure 1 or Figure 2 As shown.

[0128] For example, the first interface can be arranged along the second direction toward the outer edge of the substrate 10. There can be one first interface, which can be connected to the low-pressure valve 203 or the high-pressure valve 204 of the air conditioning system 1000. Alternatively, there can be two first interfaces, one of which is connected to the low-pressure valve 203 of the air conditioning system 1000 and the other of which is connected to the high-pressure valve 204. The second interface is arranged in a direction away from the substrate 10. The second interface can be used to connect to other components of the air conditioning system 1000 (such as the throttling element or the reversing valve 202 described below). By making the opening directions of the first interface and the second interface different, the low-pressure valve 203 or the high-pressure valve 204 of the air conditioning system 1000 can be staggered with other components, reducing the risk of interference between the low-pressure valve 203 or the high-pressure valve 204 and other components of the air conditioning system 1000. This improves the integration of the air conditioning system 1000 and enhances the ease of assembly of the air conditioning system 1000.

[0129] Combination Figure 1 , Figure 7 , Figure 9 , Figure 10 and Figure 14 At least one first interface is provided with other flow channel components 21 on both sides in the first direction. A first clearance opening 13 is formed on the substrate 10. The first clearance opening 13 is opposite to the first interface and penetrates the substrate 10 along the thickness direction of the substrate 10. The first direction and the second direction are perpendicular to the thickness direction of the substrate 10.

[0130] Since at least one first interface has other flow channels 21 respectively provided on both sides in the first direction, when the first interface is welded to the low-pressure valve 203 or the high-pressure valve 204, the other flow channels 21 located on both sides of the first interface in the first direction may block the first interface, affecting the delivery of solder to the first interface. This results in poor convenience of welding the first interface to the high-pressure valve 204 or the low-pressure valve 203, and makes it inconvenient to check the welding quality at the first interface. By forming a first clearance opening 13 on the substrate 10 that extends through the substrate 10 along the thickness direction of the substrate 10, and the first clearance opening 13 is arranged opposite to the first interface with other flow channels 21 respectively provided on both sides in the first direction, it is convenient to deliver solder to the first interface with other flow channels 21 respectively provided on both sides in the first direction through the first clearance opening 13, thereby improving the convenience of welding the first interface to the low-pressure valve 203 or the high-pressure valve 204, and making it convenient to check the welding quality at the first interface through the first clearance opening 13.

[0131] Combination Figure 7 and Figure 12 In some embodiments of this utility model, there are two first interfaces. One of the first interfaces is adapted to be connected to the low-pressure valve 203, and other flow channel components 21 are respectively provided on both sides in the first direction. The other first interface is adapted to be connected to the high-pressure valve 204, and other flow channel components 21 are provided on one side of the two sides in the first direction.

[0132] For example, the two first interfaces can be spaced apart in the first direction. The first interface connected to the low-pressure valve 203 is provided with flow channel components 21 connected to other components of the air conditioning system 1000 on both sides in the first direction. The first interface connected to the high-pressure valve 204 is provided with flow channel components 21 connected to other components of the air conditioning system 1000 on one side in the first direction. For example, the first interface connected to the high-pressure valve 204 can be provided at the outer edge of the substrate 10 in the first direction. A portion of the flow channel components 21 is provided on the side of the first interface connected to the low-pressure valve 203 away from the first interface connected to the high-pressure valve 204. Another portion of the flow channel components 21 can be provided between the two first interfaces to improve the structural compactness of the flow path module 20, which is beneficial to reduce the volume of the flow path module 20, thereby reducing the volume of the flow path integration module 100 and improving the integration degree of the flow path integration module 100.

[0133] Combination Figure 5 and Figure 6 In some embodiments of the present invention, the cross-sectional shape of the connector 22 is polygonal, circular or elliptical; or, the connector 22 has a groove 221 formed on at least one side of the two sides in the thickness direction of the substrate 10, and the width of the groove 221 is smaller than the width of the connector 22.

[0134] In some examples, the cross-sectional shape of the connector 22 in the thickness direction parallel to the substrate 10 can be a polygon such as a square, pentagon, or hexagon, or the cross-sectional shape of the connector 22 can be a circle or an ellipse. It is understood that the specific cross-sectional shape of the connector 22 can be determined according to actual production requirements, and no specific limitation is made here.

[0135] Preferably, the cross-sectional shape of the connector 22 can be constructed as square, which is beneficial to improving the processing convenience of the connector 22.

[0136] Combination Figure 5 and Figure 6 In other examples, at least one side wall of the connector 22 extending along its length direction is formed with a groove 221, the groove 221 extending through both ends of the connector 22 along its length direction, and the width of the groove 221 being less than the width of the connector 22.

[0137] For example, the connector 22 can extend along a first direction, which is the length direction of the connector 22. The width direction of the groove 221 and the connector 22 is perpendicular to the first direction and the thickness direction of the substrate 10. The side wall of the connector 22 facing the substrate 10 can be provided with a groove 221 that is recessed in a direction away from the substrate 10, and the width of the groove 221 is smaller than the width of the connector 22, so that the cross-section of the connector 22 can be constructed as U-shaped or L-shaped. Specifically, when the groove 221 is provided at the middle position of the connector 22 in the width direction, the cross-section of the connector 22 can be formed as U-shaped; when the groove 221 is provided on one side of the connector 22 in the width direction, the cross-section of the connector 22 can be formed as L-shaped.

[0138] Alternatively, grooves 221 can be provided on both the side wall of the connector 22 facing the substrate 10 and the side wall of the connector 22 away from the substrate 10. The grooves 221 are located at the middle position of the connector 22 in the width direction, and the width of the grooves 221 is smaller than the width of the connector 22, so that the cross-section of the connector 22 can be formed into an I-shape.

[0139] It is understood that the above-mentioned groove 221 is provided on the side wall of the connector 22 facing the substrate 10 or on the side wall away from the substrate 10, which is only an example of this application. The groove 221 can also be provided on the wall of the connector 22 perpendicular to the substrate 10. The specific location of the groove 221 can be determined according to the actual production requirements, and is not specifically limited here.

[0140] By providing a groove 221 on at least one side wall of the connector 22 extending along its length, it is beneficial to improve the structural strength of the connector 22 and to improve the connection and support effect of the connector 22 to the flow channel component 21 connected thereto, thereby improving the structural strength of the flow path module 20.

[0141] Combination Figures 2 to 4 In some embodiments of this utility model, the cross-sectional area of ​​the connector 22 is less than or equal to the minimum cross-sectional area of ​​the corresponding flow channel 21.

[0142] It should be noted that "the cross-sectional area of ​​the flow channel component 21" can be understood as the cross-sectional area of ​​the flow channel component 21 in the direction perpendicular to the extension of its first flow channel 211, or it can be understood as the cross-sectional area of ​​the flow channel component 21 in the direction perpendicular to the flow of the refrigerant within the flow channel component 21. "The minimum cross-sectional area of ​​the flow channel component 21" does not include the cross-sectional area of ​​its first flow channel 211. In other words, "the minimum cross-sectional area of ​​the flow channel component 21" refers to the cross-sectional area of ​​the physical structure of "flow channel component 21".

[0143] For example, the connector 22 may extend along a first direction, and the end of the connector 22 in the first direction is connected to the flow channel 21. The cross-sectional area of ​​the connector 22 in the thickness direction parallel to the substrate 10 is less than or equal to the minimum cross-sectional area of ​​the flow channel 21 connected to it, so as to reduce the heat exchange between the two flow channel 21 connected to the connector 22, which is beneficial to improving the performance of the air conditioning system 1000.

[0144] In some embodiments of this utility model, the cross-sectional area of ​​the connector 22 is greater than half of the minimum cross-sectional area of ​​the corresponding flow channel component 21, so as to ensure the structural strength of the connector 22, which helps to reduce the risk of damage to the flow path module 20 due to damage to the connector 22. Furthermore, since the connector 22 can be supported between the two flow channel components 21 corresponding to it, ensuring the structural strength of the connector 22 helps to improve the support effect of the connector 22 on the two flow channel components 21 corresponding to it.

[0145] Combination Figure 1 , Figure 2 , Figure 7 , Figure 12 and Figure 17 In some embodiments of this utility model, the air conditioning system 1000 includes an indoor heat exchanger, an outdoor heat exchanger 208, and a first throttling element 205. The first throttling element 205 is connected between the indoor heat exchanger and the outdoor heat exchanger 208. A plurality of flow channel components 21 include a first flow channel component 1 and a second flow channel component 2. The first flow channel component 1 and the second flow channel component 2 are adapted to be connected to the two ends of the first throttling element 205 respectively. The first flow channel component 1 and the second flow channel component 2 are adjacent to each other and connected by a connector 22.

[0146] In some examples, the first flow channel 1 and the second flow channel 2 are respectively connected to both ends of the first throttling element 205. The refrigerant in the air conditioning system 1000 can flow through the first flow channel 211 of the first flow channel 1 and the first flow channel 211 of the second flow channel 2 through the first throttling element 205. By arranging the first flow channel 1 and the second flow channel 2 adjacent to each other, it is convenient for the first flow channel 1 and the second flow channel 2 to be connected to the first throttling element 205 respectively, and it is also convenient for the first flow channel 1 and the second flow channel 2 to be connected through the connector 22. At the same time, since the temperature of the refrigerant flowing through both ends of the first throttling element 205 is similar, it can also be understood that the temperature of the refrigerant flowing through the first flow channel 1 and the second flow channel 2 is similar. The heat exchange between the first flow channel 1 and the second flow channel 2 through the connector 22 is small. Therefore, setting the connector 22 between the first flow channel 1 and the second flow channel 2 can improve the integration of the flow path module 20 while reducing the impact on the performance of the air conditioning system 1000 caused by heat exchange between the flow channel components 21 through the connector 22.

[0147] Combination Figure 1 , Figure 2 , Figure 7 , Figure 12 and Figure 17 In other examples, the multiple flow elements 21 include a third flow element 3 and a fourth flow element 4, which are adapted to be connected to the two ends of the outdoor heat exchanger 208 respectively, and the third flow element 3 and the fourth flow element 4 are adjacent to each other and connected by a connector 22.

[0148] For example, the third flow channel 3 can be connected to one end of the outdoor heat exchanger 208, and the fourth flow channel 4 can be connected to the other end of the outdoor heat exchanger 208. The refrigerant can flow into the outdoor heat exchanger 208 through the fourth flow channel 4 and exchange heat with the external environment. After heat exchange, the refrigerant can flow from the outdoor heat exchanger 208 into the third flow channel 3. The third flow channel 3 and the fourth flow channel 4 are arranged adjacent to each other so that the third flow channel 3 and the fourth flow channel 4 can be connected to the outdoor heat exchanger 208 respectively, and it is also convenient to connect the third flow channel 3 and the fourth flow channel 4 through the connector 22. At the same time, since the connector 22 is spaced apart from the base plate 10, the heat exchange between the third flow channel 3 and the fourth flow channel 4 through the connector 22 can be effectively reduced. This is beneficial to improve the integration of the flow path module 20 while reducing the impact on the performance of the air conditioning system 1000 caused by heat exchange between the flow channel components 21 through the connector 22.

[0149] Combination Figure 1 , Figure 2 , Figure 7 , Figure 12 and Figure 17In some other examples, multiple flow channel components 21 include a first flow channel component 1, a second flow channel component 2, a third flow channel component 3, and a fourth flow channel component 4. The first flow channel component 1 and the second flow channel component 2 are adapted to be connected to the two ends of the first throttling element 205 respectively. The first flow channel component 1 and the second flow channel component 2 are adjacent and connected by a connector 22. The third flow channel component 3 and the fourth flow channel component 4 are adapted to be connected to the two ends of the outdoor heat exchanger 208 respectively. The third flow channel component 3 and the fourth flow channel component 4 are adjacent and connected by a connector 22.

[0150] For example, one of the first flow channel 1 and the second flow channel 2 can be connected to one end of the first throttling element 205, and the other of the first flow channel 1 and the second flow channel 2 can be connected to the other end of the first throttling element 205. The third flow channel 3 can be connected to one end of the outdoor heat exchanger 208, and the fourth flow channel 4 can be connected to the other end of the outdoor heat exchanger 208. Since the first throttling element 205 is connected to the outdoor heat exchanger 208, two of the first flow channel 1, the second flow channel 2, the third flow channel 3, and the fourth flow channel 4 can be simplified to one. For example, the second flow channel 2 can be connected to the inlet of the first throttling element 205. The first flow channel component 1 can be connected to the outlet of the first throttling element 205, the fourth flow channel component 4 can be connected to the inlet of the outdoor heat exchanger 208, and the third flow channel component 3 can be connected to the outlet of the outdoor heat exchanger 208. At the same time, the outlet of the first throttling element 205 is connected to the inlet of the outdoor heat exchanger 208. In this case, only the first flow channel component 1 or the fourth flow channel component 4 is needed to connect the first throttling element 205 to the outdoor heat exchanger 208, which effectively simplifies the number of flow channel components 21, thereby simplifying the structure of the flow path module 20 and improving the integration of the flow path module 20, so as to improve the integration of the flow path integration module 100.

[0151] like Figure 7 As shown, in some embodiments of this utility model, the interfaces 212 of all flow channel components 21 are arranged to avoid the substrate 10.

[0152] For example, when the various components of the air conditioning system 1000 can be connected only through the first flow channel 211 of the flow path module 20, the interfaces 212 of all flow channel components 21 can be arranged to avoid the substrate 10. For example, the interfaces 212 can be arranged in a direction away from the substrate 10, or the interfaces 212 can be arranged in a direction perpendicular to the thickness of the substrate 10 (e.g., a first direction or a second direction), so that the interfaces 212 of all flow channel components 21 can avoid the substrate 10, preventing the substrate 10 from blocking the interfaces 212, and facilitating the connection between the various components of the air conditioning system 1000 and the interfaces 212.

[0153] Or, combine Figures 7 to 11The substrate 10 has at least one second flow channel 14 that penetrates the substrate 10. The surface of the second flow channel 14 facing away from the flow path module 20 forms a first external interface 141. The multiple interfaces 212 of the flow path module 20 include a second external interface and an internal interface. The second external interface is disposed to avoid the substrate 10, and the internal interface is disposed facing the substrate 10 and is connected to the corresponding first external interface 141.

[0154] For example, in order to reasonably allocate the installation positions of the components of the air conditioning system 1000 connected to the flow path integration module 100, at least one component of the air conditioning system 1000 can be disposed on the side of the substrate 10 away from the flow path module 20. The substrate 10 is provided with a second flow channel 14 that extends through it along its thickness direction, and a first external interface 141 is formed on the side of the second flow channel 14 away from the flow path module 20. The first external interface 141 can be used to connect with the component disposed on the side of the substrate 10 away from the flow path module 20. Correspondingly, the flow path module 20 is provided with an internal interface facing the substrate 10. The internal interface communicates with the corresponding first external interface 141, so that the component disposed on the side of the substrate 10 away from the flow path module 20 can be connected to the flow path integration module 100.

[0155] The flow path module 20 also has a second external interface. The second external interface can be set away from the substrate 10 or perpendicular to the thickness direction of the substrate 10 to achieve the second external interface avoiding the substrate 10. The second external interface can be used to connect with the components of the air conditioning system 1000 located on the side of the substrate 10 facing the flow path module 20. Thus, the flow path integration module 100 can connect the components on both sides of its thickness direction, thereby improving the integration of the air conditioning system 1000 while reasonably allocating the installation positions of each component of the air conditioning system 1000 connected to the flow path integration module 100.

[0156] Reference Figure 15 In some embodiments of this utility model, the plurality of flow channel components 21 include a first flow channel component 1, a second flow channel component 2, a fifth flow channel component 5, and a sixth flow channel component 6. The interfaces 212 of the first flow channel component 1, the second flow channel component 2, and the sixth flow channel component 6 are all disposed to avoid the substrate 10. At least one interface 212 of the fifth flow channel component 5 is disposed to avoid the substrate 10. The first flow channel component 1 is adapted to be connected between the outdoor heat exchanger 208 and the first throttling element 205. The second flow channel component 2 and the fifth flow channel component 5 are both adapted to be connected between the first throttling element 205 and the high-pressure valve 204. The sixth flow channel component 6 is adapted to be connected between the reversing valve 202 and the low-pressure valve 203.

[0157] For example, the first flow channel component 1 may be provided with two interfaces 212, both interfaces 212 being disposed away from the substrate 10. One of the two interfaces 212 is connected to the first throttling element 205, and the other of the two interfaces 212 is connected to the outdoor heat exchanger 208; the second flow channel component 2 may be provided with two interfaces 212, one of the two interfaces 212 may be connected to the first throttling element 205, and the other of the two interfaces 212 may be indirectly connected to the high-pressure valve 204; the fifth flow channel component 5 may be provided with two interfaces 212, one of the two interfaces 212 may be disposed along the substrate 10 and connected to the high-pressure valve 204, and the other of the two interfaces 212 may be indirectly connected to the high-pressure valve 204. Another interface 212 in the second flow channel component 2 can be connected to the interface 212 that is indirectly connected to the high pressure valve 204, thereby enabling both the second flow channel component 2 and the fifth flow channel component 5 to be connected between the first throttling element 205 and the high pressure valve 204; the sixth flow channel component 6 can be provided with two interfaces 212, one of which can be set away from the substrate 10, and the other of which can be set along the thickness direction perpendicular to the substrate 10. The interface 212 of the sixth flow channel component 6 that is set away from the substrate 10 can be connected to the reversing valve 202, and the interface 212 of the sixth flow channel component 6 that is set perpendicular to the thickness direction of the substrate 10 can be connected to the reversing valve 202.

[0158] The first flow channel component 1 and the sixth flow channel component 6 are spaced apart along the first direction and connected by a connector 22. The second flow channel component 2 and the fifth flow channel component 5 are spaced apart on one side of the first flow channel component 1 in the second direction and are opposite to each other along the first direction. Each of the second flow channel component 2 and the fifth flow channel component 5 is connected to the first flow channel component 1 by a connector 22. This helps to improve the integration of the flow path module 20 and reduce the volume of the flow path module 20, thereby improving the integration of the flow path integration module 100 and reducing the volume of the flow path integration module 100.

[0159] Furthermore, the interface 212 of the sixth flow channel 6, which is suitable for connection with the low-pressure valve 203, and the interface 212 of the fifth flow channel 5, which is suitable for connection with the high-pressure valve 204, are both arranged along the second direction toward the outer edge of the substrate 10, and their central axes are parallel, with the first direction, the second direction, and the thickness direction of the substrate 10 being perpendicular to each other.

[0160] By arranging the interface 212 of the sixth flow channel component 6 connected to the low-pressure valve 203 and the interface 212 of the fifth flow channel component 5 connected to the high-pressure valve 204 both along the second direction toward the outer edge of the substrate 10, it is convenient to arrange the high-pressure valve 204 and the low-pressure valve 203 on one side of the flow path integration module 100 in the second direction, so as to avoid interference between the high-pressure valve 204 and the low-pressure valve 203 and the components arranged on one side of the substrate 10 in the thickness direction, thereby improving the assembly convenience of the air conditioning system 1000.

[0161] By making the central axes of the interface 212 of the sixth flow channel component 6 connected to the low-pressure valve 203 and the interface 212 of the fifth flow channel component 5 connected to the high-pressure valve 204 parallel, it is beneficial to prevent interference between the low-pressure valve 203 and the high-pressure valve 204. At the same time, it is beneficial to avoid the low-pressure valve 203 and the high-pressure valve 204 occupying too much space on the flow path integration module 100, which would increase the volume of the flow path integration module 100.

[0162] Combination Figure 7 , Figure 8 and Figure 12 In some embodiments of this utility model, the multiple flow channel components 21 further include a third flow channel component 3. The third flow channel component 3 is spaced apart on the other side of the first flow channel component 1 in the second direction and is adapted to be connected between the reversing valve 202 and the outdoor heat exchanger 208. A connecting member 22 is provided between the third flow channel component 3 and the first flow channel component 1, and the interfaces 212 of the third flow channel component 3 are all arranged to avoid the substrate 10.

[0163] For example, the third flow channel 3 is disposed on the side of the first flow channel 1 away from the second flow channel 2 and the fifth flow channel 5 in the second direction, and the third flow channel 3 can be connected to the first flow channel 1 through the connector 22 to improve the integration of the flow path module 20. The third flow channel 3 can be provided with two interfaces 212 disposed away from the substrate 10 along the thickness direction of the substrate 10. One of the two interfaces 212 is connected to the reversing valve 202, and the other of the two interfaces 212 is connected to the outdoor heat exchanger 208. The refrigerant flowing out of the outdoor heat exchanger 208 can flow from the third flow channel 3 to the reversing valve 202.

[0164] Combination Figures 7 to 11 , Figure 12 and Figure 17In some embodiments of this utility model, the air conditioning system 1000 includes a compressor 201 and an economizer 210. The economizer 210 has a first heat exchange flow path 2101 and a second heat exchange flow path 2102 that exchange heat with each other. The outlet of the first heat exchange flow path 2101 is connected to the air supply port 2013 of the compressor 201. The substrate 10 has at least four first external interfaces 141 on the side opposite to the flow path module 20, wherein the four first external interfaces 141 are adapted to be connected to the economizer 210. A fifth flow channel component 5 communicates with one of the first external interfaces 141 and has a second external interface, so that the fifth flow channel component 5 is adapted to be connected between the high pressure valve 204 and the second heat exchange flow path 2102. The plurality of flow channel components 21 also include a seventh flow channel component 7, a second flow channel component 8, a third flow channel component 9, a third flow channel component 10 ... The seventh flow channel 7 is connected to one of the first external interfaces 141 and has multiple second external interfaces, so that the seventh flow channel 7 is suitable for connection between the second heat exchange flow path 2102, the second flow channel 2 and the eighth flow channel 8. The eighth flow channel 8 is connected to one of the first external interfaces 141 and has a second external interface, so that one end of the eighth flow channel 8 is suitable for connection to the seventh flow channel 7 through the second throttling element 206 and the other end is suitable for connection to the inlet of the first heat exchange flow path 2101. The ninth flow channel 9 is connected to one of the first external interfaces 141 and has a second external interface, so that the ninth flow channel 9 is suitable for connection between the outlet of the first heat exchange flow path 2101 and the air inlet 2013.

[0165] For example, both the first heat exchange flow path 2101 and the second heat exchange flow path 2102 are provided with an inlet and an outlet. The inlet and outlet of the first heat exchange flow path 2101 and the second heat exchange flow path 2102 are provided with a first external interface 141 corresponding to each other, so that the first heat exchange flow path 2101 and the second heat exchange flow path 2102 can be connected to the flow path integration module 100 respectively, thereby improving the integration of the air conditioning system 1000.

[0166] The fifth flow channel component 5 has a second external interface and an internal interface. The second external interface of the fifth flow channel component 5 can be connected to the high-pressure valve 204, and the internal interface of the fifth flow channel component 5 can be connected to a first external interface 141 connected to the inlet of the second heat exchange flow path 2102. The refrigerant can flow between the high-pressure valve 204 and the second heat exchange flow path 2102 through the fifth flow channel component 5.

[0167] The seventh flow channel 7 has an internal interface on the side facing the substrate 10. The internal interface of the seventh flow channel 7 can be connected to the first external interface 141 connected to the inlet of the second heat exchange flow path 2102. At the same time, the seventh flow channel 7 has two second external interfaces spaced apart on the side away from the substrate 10. Specifically, two first flow channels 211 can be formed in the seventh flow channel 7. The two first flow channels 211 can extend in different directions, so that the refrigerant flowing into the seventh flow channel 7 from the second heat exchange flow path 2102 can be split in the seventh flow channel 7. Each of the two first flow channels 211 is provided with a second external interface 212. One of the two second external interfaces is connected to the second flow channel 2, and the other of the two second external interfaces is connected to one end of the second throttling element 206.

[0168] The eighth flow channel 8 can be provided with an internal interface on one side facing the substrate 10. The internal interface of the eighth flow channel 8 is connected to the first external interface 141 which is connected to the inlet of the first heat exchange flow path 2101. The eighth flow channel 8 is also provided with a second external interface, which is connected to the other end of the second throttling element 206. Thus, one end of the eighth flow channel is connected to the seventh flow channel 7 through the second throttling element 206, and the other end is connected to the inlet of the first heat exchange flow path 2101.

[0169] The ninth flow channel component 9 is provided with an internal interface, which can be connected to the first external interface 141 that is located opposite to the outlet of the first heat exchange flow path 2101. At the same time, the ninth flow channel component 9 is provided with a second external interface, which can be connected to the air supply port 2013 of the compressor 201.

[0170] Combination Figure 1 , Figures 7 to 11 and Figure 12 In some embodiments of this utility model, the seventh flow channel 7 and the eighth flow channel 8 are both spaced apart on the side of the sixth flow channel 6 away from the first flow channel 1, and the opposite sides of the eighth flow channel 8 are respectively connected to the sixth flow channel 6 and the seventh flow channel 7 through the connecting member 22. The ninth flow channel 9 is spaced apart between the first flow channel 1 and the fifth flow channel 5, and the opposite sides of the ninth flow channel 9 are respectively connected to the first flow channel 1 and the fifth flow channel 5 through the connecting member 22.

[0171] For example, if the first flow channel 1 is disposed on one side of the sixth flow channel 6 in the first direction via a connector 22, then the seventh flow channel 7 and the eighth flow channel 8 can be disposed on the side of the sixth flow channel 6 away from the first flow channel 1 in the first direction. The opposite sides of the eighth flow channel 8 in the first direction are respectively connected to the sixth flow channel 6 and the seventh flow channel 7 via connectors 22. In the second direction, the ninth flow channel 9 is disposed between the first flow channel 1 and the fifth flow channel 5, and the opposite sides of the ninth flow channel 9 in the second direction are respectively connected to the first flow channel 1 and the fifth flow channel 5 via connectors 22.

[0172] Therefore, by setting multiple connectors 22, the first flow channel component 1, the second flow channel component 2, the fifth flow channel component 5, the sixth flow channel component 6, the seventh flow channel component 7, the eighth flow channel component 8, and the ninth flow channel component 9 can be connected into a whole, thereby improving the integration of the flow path module 20 and improving the assembly efficiency of the flow path module 20.

[0173] In some specific embodiments, when the air conditioning system 1000 is in cooling mode, the first throttling element 205 is fully open and the second throttling element 206 is closed. At this time, the temperature of one of the two first flow channels 211 connected to both ends of the first throttling element 205 can be 30°C, and the temperature of the other can be 40°C. When the air conditioning system 1000 is in heating mode, before the first throttling element 205 throttles the refrigerant, the temperature of one of the two first flow channels 211 connected to both ends of the first throttling element 205 can be 15°C, and the temperature of the other can be 25°C. After the refrigerant is throttled, the temperature of one of the two first flow channels 211 connected to both ends of the first throttling element 205 can be 5°C, and the temperature of the other can be 15°C. At the same time, the second throttling element 206 works. Before the second throttling element 206 throttles the refrigerant, the temperature of one of the two first flow channels 211 connected to both ends of the second throttling element 206 can be 20°C, and the temperature of the other can be 30°C. After the second throttling element 206 throttles the refrigerant, the temperature of one of the two first flow channels 211 connected to both ends of the second throttling element 206 can be 15°C, and the temperature of the other can also be 25°C.

[0174] Therefore, the temperature difference between the first flow channel 1 and the second flow channel 2 connected at both ends of the first throttling element 205 is small, and the temperature difference between the seventh flow channel 7 and the eighth flow channel 8 connected at both ends of the second throttling element 206 is small. Thus, the connection of the first flow channel 1 and the second flow channel 2 via the connector 22, and the connection of the seventh flow channel 7 and the eighth flow channel 8 via the connector 22, have little impact on the heat transfer between the flow channel 21.

[0175] In some other embodiments of the present invention, the flow path module 20 includes a first part and a second part. The first part is disposed on one side of the substrate 10 in the thickness direction, and the second part is disposed on the other side of the substrate 10 in the thickness direction. The second part includes at least four flow channel components 21, wherein each of the four flow channel components 21 has a third flow channel. The four third flow channels are correspondingly and connected to the inlet of the first heat exchange flow path 2101, the outlet of the first heat exchange flow path 2101, the inlet of the second heat exchange flow path 2102, and the inlet of the third heat exchange flow path of the economizer 210.

[0176] The inlet of the first heat exchange flow path 2101 and the outlet of the second heat exchange flow path 2102 are arranged adjacent to each other, and the outlet of the first heat exchange flow path 2101 and the inlet of the second heat exchange flow path 2102 are arranged adjacent to each other. Correspondingly, the third flow channel connected to the inlet of the first heat exchange flow path 2101 and the third flow channel connected to the outlet of the second heat exchange flow path 2102 are arranged adjacent to each other, and the two third flow channels are connected by a connector 22. The third flow channel connected to the outlet of the first heat exchange flow path 2101 and the third flow channel connected to the inlet of the second heat exchange flow path 2102 are arranged adjacent to each other, and the two third flow channels are connected by a connector 22.

[0177] Combination Figure 12 and Figure 17 According to an embodiment of the present invention, an air conditioning system 1000 includes: a refrigerant circuit and a flow path integration module 100. The refrigerant circuit includes a compressor 201, a reversing valve 202, a low-pressure valve 203, an indoor heat exchanger, a high-pressure valve 204, a first throttling element 205, and an outdoor heat exchanger 208. The flow path integration module 100 is configured to satisfy at least one of the following conditions so that the flow path integration module 100 is connected to the refrigerant circuit, thereby allowing the refrigerant flowing in the refrigerant circuit to circulate in the refrigerant circuit through the flow path integration module 100.

[0178] Condition A1: At least one flow path 21 is connected between the reversing valve 202 and the low-pressure valve 203. For example, a flow path 21 may be provided between the reversing valve 202 and the low-pressure valve 203. The reversing valve 202 and the low-pressure valve 203 can be connected through the flow path 21 provided between them, so that the refrigerant can flow between the reversing valve 202 and the low-pressure valve 203.

[0179] It is understandable that the number of flow passage components 21 connected between the reversing valve 202 and the low-pressure valve 203 can be determined according to actual usage requirements, as long as at least one flow passage component 21 is connected between the reversing valve 202 and the low-pressure valve 203.

[0180] Condition A2: At least one flow channel 21 is connected between the high-pressure valve 204 and the first throttling element 205. For example, a flow channel 21 can be provided between the high-pressure valve 204 and the first throttling element 205. The high-pressure valve 204 and the first throttling element 205 can be connected through the flow channel 21 provided between them, so that the refrigerant can flow between the high-pressure valve 204 and the first throttling element 205.

[0181] It is understandable that the number of flow channel components 21 connected between the high-pressure valve 204 and the first throttling element 205 can be determined according to actual usage requirements, as long as at least one flow channel component 21 is connected between the high-pressure valve 204 and the first throttling element 205.

[0182] Condition A3: At least one flow channel 21 is connected between the first throttling element 205 and the outdoor heat exchanger 208. For example, a flow channel 21 can be provided between the first throttling element 205 and the outdoor heat exchanger 208. The first throttling element 205 and the outdoor heat exchanger 208 can be connected through the flow channel 21 provided between them, so that the refrigerant can flow between the first throttling element 205 and the outdoor heat exchanger 208.

[0183] It is understandable that the number of flow channel components 21 connected between the first throttling element 205 and the outdoor heat exchanger 208 can be determined according to actual usage requirements, as long as at least one flow channel component 21 is connected between the first throttling element 205 and the outdoor heat exchanger 208.

[0184] Condition A4: At least one flow path 21 is connected between the outdoor heat exchanger 208 and the reversing valve 202. For example, a flow path 21 can be provided between the outdoor heat exchanger 208 and the reversing valve 202. The outdoor heat exchanger 208 and the reversing valve 202 can be connected through the flow path 21 provided between them, so that the refrigerant can flow between the outdoor heat exchanger 208 and the reversing valve 202.

[0185] It is understandable that the number of flow channel components 21 connected between the outdoor heat exchanger 208 and the reversing valve 202 can be determined according to actual usage requirements, as long as at least one flow channel component 21 is connected between the outdoor heat exchanger 208 and the reversing valve 202.

[0186] In some examples, the air conditioning system 1000 may satisfy condition A1, condition A2, condition A3, or condition A4 individually; in other examples, the air conditioning system 1000 may satisfy any two of conditions A1 to A4; in still other examples, the air conditioning system 1000 may satisfy any three of conditions A1 to A4; and in some other examples, the air conditioning system 1000 may satisfy all of conditions A1 to A4.

[0187] It is understandable that the specific conditions that the air conditioning system 1000 needs to meet can be determined according to actual production requirements, and no specific restrictions are made here, as long as the refrigerant circuit of the air conditioning system 1000 can be connected through the flow path integration module 100.

[0188] According to the embodiment of the present invention, the air conditioning system 1000 includes the aforementioned flow path integration module 100. By providing a connector 22, multiple flow channel components 21 can be connected to form a flow path module 20, thereby improving the integration of the flow path module 20 and reducing the assembly difficulty of the flow path module 20. Furthermore, by further spacing the connector 22 from the substrate 10, it is not necessary to connect the connector 22 to the substrate 10, which helps to reduce the processing difficulty and processing cost of the flow path integration module 100. Moreover, an air gap can exist between the connector 22 and the substrate 10, thereby increasing the contact area between the connector 22 and the substrate 10 and the air, thereby increasing the heat dissipation area of ​​the connector 22. This helps to reduce the heat exchange between the two first flow channels 211 connected to the same connector 22 through the connector 22, thereby helping to reduce the impact of the connector 22 on the working performance of the air conditioning system 1000.

[0189] Combination Figure 12 and Figure 17 In some embodiments of this utility model, the refrigerant circuit further includes an electronically controlled radiator 209, and the air conditioning system 1000 further includes an electronically controlled device. The electronically controlled radiator 209 and the electronically controlled device are thermally connected. The plurality of flow channel components 21 include a second flow channel component 2 and a fifth flow channel component 5. One end of the electronically controlled radiator 209 is connected to the high-pressure valve 204 at least through the fifth flow channel component 5, and the other end is connected to the first throttling element 205 at least through the second flow channel component 2.

[0190] For example, the second flow channel component 2 is provided with two interfaces 212 at each end. One of the two interfaces 212 is used to connect to the electronically controlled radiator 209, and the other of the two interfaces 212 is used to connect to the first throttling element 205. The fifth flow channel component 5 is provided with two interfaces 212. One of the two interfaces 212 is connected to the high-pressure valve 204, and the other of the two interfaces 212 is connected to the electronically controlled radiator 209. This realizes that the electronically controlled radiator 209 is connected between the first throttling element 205 and the high-pressure valve 204. Regardless of whether the air conditioning system 1000 is in cooling mode or heating mode, the temperature of the refrigerant flowing to the electronically controlled radiator 209 is reduced. Therefore, when the refrigerant flows into the electronically controlled radiator 209, it can exchange heat with the electronically controlled device, thereby improving the heat dissipation efficiency of the electronically controlled device.

[0191] The thermally conductive connection between the electronically controlled heat sink 209 and the electronically controlled device includes, but is not limited to, direct contact between the electronically controlled heat sink 209 and the electronically controlled device, or connection between the electronically controlled heat sink 209 and the electronically controlled device through a thermally conductive component (such as thermally conductive adhesive). The specific connection method between the electronically controlled heat sink 209 and the electronically controlled device can be determined according to actual production requirements, and is not specifically limited here.

[0192] Combination Figure 12 and Figure 17 In some embodiments of this utility model, the refrigerant circuit further includes an economizer 210. The economizer 210 has a first heat exchange flow path 2101 and a second heat exchange flow path 2102 that exchange heat with each other. Multiple flow channel components 21 include a fifth flow channel component 5, a seventh flow channel component 7, an eighth flow channel component 8, and a ninth flow channel component 9. One end of the second heat exchange flow path 2102 is connected to the high-pressure valve 204 through the fifth flow channel component 5, and the other end is connected to the first throttling element 205 through at least the seventh flow channel component 7. It is also connected to the inlet of the first heat exchange flow path 2101 through the seventh flow channel component 7, the eighth flow channel component 8, and the second throttling element 206. The outlet of the first heat exchange flow path 2101 is connected to the gas supply port 2013 of the compressor 201 through the ninth flow channel component 9.

[0193] For example, both the first heat exchange flow path 2101 and the second heat exchange flow path 2102 are provided with an inlet and an outlet. The inlet and outlet of the first heat exchange flow path 2101 and the second heat exchange flow path 2102 are provided with a first external interface 141 corresponding to each other, so that the first heat exchange flow path 2101 and the second heat exchange flow path 2102 can be connected to the flow path integration module 100 respectively, thereby improving the integration of the air conditioning system 1000.

[0194] The fifth flow channel component 5 has a second external interface and an internal interface. The second external interface of the fifth flow channel component 5 can be connected to the high-pressure valve 204, and the internal interface of the fifth flow channel component 5 can be connected to a first external interface 141 connected to the inlet of the second heat exchange flow path 2102. The refrigerant can flow between the high-pressure valve 204 and the second heat exchange flow path 2102 through the fifth flow channel component 5.

[0195] The seventh flow channel 7 has an internal interface on the side facing the substrate 10. The internal interface of the seventh flow channel 7 can be connected to the first external interface 141 connected to the inlet of the second heat exchange flow path. At the same time, the seventh flow channel 7 has two second external interfaces spaced apart on the side away from the substrate 10. Specifically, two first flow channels 211 can be formed in the seventh flow channel 7. The two first flow channels 211 can extend in different directions, so that the refrigerant flowing into the seventh flow channel 7 from the second heat exchange flow path 2102 can be split in the seventh flow channel 7. Each of the two first flow channels 211 is provided with a second external interface 212. One of the two second external interfaces can be connected to the second flow channel 2 through the electronically controlled heat sink 209. The other of the two second external interfaces can be connected to the second throttling element 206 and connected to the eighth flow channel 8 through the second throttling element 206.

[0196] The eighth flow channel 8 can be provided with an internal interface on one side facing the substrate 10. The internal interface of the eighth flow channel 8 is connected to the first external interface 141 connected to the inlet of the first heat exchange flow path 2101. The eighth flow channel 8 is also provided with a second external interface. The second external interface of the eighth flow channel 8 is connected to one of the second external interfaces of the seventh flow channel 7 through a second throttling element 206. This allows a second throttling element 206 to be provided between the seventh flow channel 7 and the first heat exchange flow path 2101, and the second throttling element 206 can throttle the refrigerant flowing from the seventh flow channel 7 to the first heat exchange flow path 2101.

[0197] The ninth flow channel component 9 is provided with an internal interface, which can be connected to the first external interface 141 that is located opposite to the outlet of the first heat exchange flow path 2101. At the same time, the ninth flow channel component 9 is provided with a second external interface, which can be connected to the air supply port 2013 of the compressor 201.

[0198] Combination Figure 16 and Figure 17 In some embodiments of this utility model, a third throttling element 207 is provided in the seventh flow channel 7. The third throttling element 207 is located in the first flow channel 211 of the seventh flow channel 7, which is connected to the second throttling element 206. The third throttling element 207 throttles the refrigerant flowing through the first flow channel 211 to the second throttling element 206. When the refrigerant flows through the second throttling element 206, the second throttling element 206 can further throttle the refrigerant.

[0199] In some specific embodiments of this utility model, the first throttling element 205 and the second throttling element 206 can be configured as electronic expansion valves, and the opening degree of the electronic expansion valves is adjustable; the third throttling element 207 can be configured as a spiral throttling pin, and the cross-sectional area of ​​the first flow channel 211 can be adjusted by selectively screwing the spiral throttling pin into or out of the first flow channel 211, thereby adjusting the flow rate and pressure of the refrigerant in the first flow channel 211.

[0200] Combination Figure 1 and Figure 17 In some embodiments of this utility model, the refrigerant circuit includes at least one filter element disposed between the high-pressure valve 204 and the outdoor heat exchanger 208, and the filter element is installed at the corresponding interface 212.

[0201] In some examples, the refrigerant circuit may include a filter element, which may be located at the port 212 of the high-pressure valve 204 or at the port 212 of the outdoor heat exchanger 208; in other examples, the refrigerant circuit may include two filters, one of which may be located at the port 212 of the high-pressure valve 204 and the other of which may be located at the port 212 of the outdoor heat exchanger 208.

[0202] By installing filters, the refrigerant can be filtered during its flow, reducing the risk of impurities carried by the refrigerant clogging the high-pressure valve 204 or the outdoor heat exchanger 208, which helps to extend the service life of the air conditioning system 1000.

[0203] like Figure 16 As shown, in some specific embodiments of this utility model, the filter element includes a mounting flange 2201 and a filter screen 2202, and the filter screen 2202 can be installed to the corresponding interface 212 through the mounting flange 2201.

[0204] In some embodiments of this utility model, the filter and the third throttling element 207 can be pre-installed at the corresponding interface 212 of the flow path module 20, and then the flow path module 20, the substrate 10, and the various components of the air conditioning system 1000 (such as the outdoor heat exchanger 208, the high-pressure valve 204, and the low-pressure valve 203) are welded to the corresponding interface 212 of the flow path integration module 100.

[0205] Among them, combined Figure 1 and Figure 12Each of the interfaces 212 on the side of the flow path module 20 facing away from the substrate 10 can be provided with a transition tube 230, and connected to the corresponding component through the transition tube 230. After each component is positioned and installed with the flow path integration module 100, each component can be welded to the corresponding transition tube 230 along the direction from the center of the flow path integration module 100 to the outer edge of the substrate 10.

[0206] It should be noted that, considering that valves such as the first throttling element 205 and the second throttling element 206 are easily damaged by high temperatures, the valves need to be cooled during the welding process.

[0207] Combination Figure 1 and Figure 17 In some embodiments of this utility model, there are multiple filter elements, including: a first filter element 2203, a second filter element 2204, and a third filter element 2205. The first filter element 2203 is connected in series between the first throttling element 205 and the outdoor heat exchanger 208. The first filter element 2203 is installed at the interface 212 of the flow channel element 21 located between the first throttling element 205 and the outdoor heat exchanger 208. The refrigerant circuit also includes an electronically controlled radiator 209. The air conditioning system 1000 also includes an electronically controlled device. The electronically controlled radiator 209 is connected between the high-pressure valve 204 and the first throttling element 205 and is thermally connected to the electronically controlled device. The second filter element 2204 is connected in series between the electronically controlled radiator 209 and the first throttling element 205. The third filter element 2205 is connected in series at the end of the electronically controlled radiator 209 away from the first throttling element 205.

[0208] For example, the first flow channel 1 is provided with two interfaces 212. The first throttling element 205 and the outdoor heat exchanger 208 are respectively connected to the first flow channel 1 through the two interfaces 212. The first filter element 2203 can be provided at the interface 212 of the first flow channel 1 that is connected to the outdoor heat exchanger 208.

[0209] The second flow channel component 2 is provided with two interfaces 212. One of the two interfaces 212 is connected to the first throttling element 205, and the other of the two interfaces 212 is connected to the electronically controlled heat sink 209. At the same time, the electronically controlled heat sink 209 can be connected to the second heat exchange flow path 2102 through the seventh flow channel component 7. Since the second heat exchange flow path 2102 can be connected to the high-pressure valve 204 through the fifth flow channel component 5, the electronically controlled heat sink 209 can be connected between the high-pressure valve 204 and the first throttling element 205. The second filter element 2204 can be set at the interface 212 between the seventh flow channel component 7 and the electronically controlled heat sink 209, and the third filter element 2205 can be set at the interface 212 between the fifth flow channel component 5 and the high-pressure valve 204.

[0210] Therefore, by setting the first filter element 2203, the second filter element 2204 and the third filter element 2205 respectively, the impurities carried by the refrigerant when entering each component are reduced, which helps to improve the service life of the air conditioning system 1000.

[0211] Combination Figure 1 , Figure 7 and Figure 12 In some embodiments of this utility model, the flow path integration module 100 further includes a welding ring 23. The welding ring 23 is integrally connected to the interface 212 corresponding to the back substrate 10 and protrudes from the side surface of the corresponding flow channel component 21 opposite to the substrate 10 in the direction away from the substrate 10. The welding ring 23 is connected to the refrigerant circuit through a transition tube 230, which is inserted into and welded to the welding ring 23.

[0212] It should be noted that "the wall thickness of the welding ring 23" can be understood as the dimension of the annular wall surface forming the welding ring 23 in its radial direction.

[0213] For example, at least one of the interfaces 212 of the flow path module 20 is located on the side of the flow path module 20 away from the substrate 10. The interface 212 located on the side of the flow path module 20 away from the substrate 10 can be connected to the refrigerant circuit through the transition tube 230. The transition tube 230 can be inserted and engaged with the welding ring 23 at the corresponding interface 212 to facilitate the positioning and assembly of the transition tube 230 and the flow path module 20. After the transition tube 230 and the welding ring 23 are inserted and engaged, the transition tube 230 and the welding ring 23 can be connected.

[0214] The wall thickness of the welding ring 23 is greater than or equal to 1 mm and less than or equal to 3 mm. By designing the wall thickness of the welding ring 23, it is beneficial to reduce the processing difficulty of the welding ring 23, and at the same time, it is beneficial to reduce the material used in the welding ring 23, thereby reducing the production cost of the flow path integrated module 100.

[0215] When the wall thickness of the welding ring 23 is less than 1mm, the processing precision requirement of the welding ring 23 is high, which makes the processing of the welding ring 23 difficult. When the wall thickness of the welding ring 23 is greater than 3mm, the welding ring 23 requires more material, which leads to a higher material cost of the flow path integration module 100, and consequently a higher production cost of the flow path module 20.

[0216] Combination Figure 12 as well as Figures 14 to 17In some embodiments of this utility model, at least one flow channel component 21 is connected to the reversing valve 202. The refrigerant circuit also includes a gas-liquid separator 240. The gas-liquid separator 240 includes a separation body 241, an inlet pipe 242, and a gas outlet pipe 243. The separation body 241 has a separation chamber and is located on the other side of the thickness of the substrate 10. The inlet pipe 242 and the gas outlet pipe 243 are both located at one end of the separation body 241 adjacent to the substrate 10. The inlet pipe 242 is arranged to avoid all interfaces 212 so that the inlet pipe 242 passes through the flow path integration module 100 and is connected to the reversing valve 202. The inlet pipe 242 and the flow channel component 21 are respectively connected to different valve ports of the reversing valve 202.

[0217] For example, the reversing valve 202 can be located on the side of the flow path module 20 away from the substrate 10, and the separation body 241 can be disposed on the side of the substrate 10 away from the flow path module 20 in the thickness direction. The inlet pipe 242 and the gas outlet pipe 243 are respectively disposed on the side of the separation body 241 close to the substrate 10 and connected to the separation body 241, so that the separation body 241 can be connected to the reversing valve 202 through the inlet pipe 242. The refrigerant passing through the reversing valve 202 can flow into the separation chamber of the separation body 241 through the inlet pipe 242 and realize the separation of gaseous refrigerant and liquid refrigerant in the separation chamber. The separated gaseous refrigerant can flow out from the separation chamber through the gas outlet pipe 243.

[0218] In this configuration, the inlet pipe 242 is designed to bypass all interfaces 212, allowing it to bypass the flow path integration module 100 and connect to the reversing valve 202. For example, the inlet pipe 242 can pass through the substrate 10, and in the projection plane of the substrate 10 in the thickness direction, the orthographic projection plane of the inlet pipe 242 at the location where it passes through the substrate 10 is offset from the orthographic projection plane of all interfaces 212. This allows the inlet pipe 242 to bypass the flow path integration module 100 and connect to the reversing valve 202, eliminating the need to connect the inlet pipe 242 and the reversing valve 202 to the integration module separately. This achieves the integrated configuration of the flow path integration module 100, the reversing valve 202, and the gas-liquid separator 240, effectively simplifying the connection between the integration module, the reversing valve 202, and the gas-liquid separator 240, reducing the production and processing costs of the air conditioning system 1000, and improving the production and processing efficiency of the air conditioning system 1000.

[0219] Reference Figure 15In some examples, flow path component 21 may include a sixth flow path component 6. The reversing valve 202 may be connected only to the sixth flow path component 6 of the flow path module 20. Simultaneously, the reversing valve 202 may be connected to the inlet pipe 242 of the gas-liquid separator 240. Through the sixth flow path component 6 and the gas-liquid separator 240, the connection positions of the two valve ports of the reversing valve 202 can be determined, thereby enabling the positioning and installation of the reversing valve 202. This effectively simplifies the structure of the flow path module 20 and reduces its production cost. Figure 12 and Figure 14 The flow channel component 21 may include a sixth flow channel component 6 and a third flow channel component 3. The reversing valve 202 may be connected to the third flow channel component 3 and the sixth flow channel component 6 respectively. At the same time, the reversing valve 202 is also connected to the inlet pipe 242 of the gas-liquid separator 240, so that the connection positions of the three valve ports of the reversing valve 202 can be determined, thereby improving the convenience of positioning and installation of the reversing valve 202.

[0220] Combination Figures 12 to 14 In some embodiments of this utility model, the inlet pipe 242 passes through the substrate 10 along the thickness direction of the substrate 10 and extends to the side where the flow path module 20 is located, and the gas outlet pipe 243 is spaced apart on the outer periphery of the substrate 10.

[0221] For example, the inlet pipe 242 is located on the side of the separation body 241 opposite to the substrate 10 in the thickness direction of the substrate 10, and the inlet pipe 242 can pass through the substrate 10 from the separation body 241 along the thickness direction of the substrate 10 so as to connect with the reversing valve 202 located on the side of the flow path module 20 away from the substrate 10. At the same time, the reversing valve 202 is connected to the flow path module 20, thereby realizing the integrated arrangement of the reversing valve 202, the flow path integration module 100 and the gas-liquid separator 240, without having to connect the reversing valve 202 and the gas-liquid separator 240 to the flow path integration module 100 separately. This effectively simplifies the connection between the integration module, the reversing valve 202 and the gas-liquid separator 240, reduces the production and processing cost of the air conditioning system 1000, and helps to improve the production and processing efficiency of the air conditioning system 1000.

[0222] The gas outlet pipe 243 is used to connect to the suction port 2011 of the compressor 201. By arranging the gas outlet pipes 243 at intervals on the outer periphery of the substrate 10, it is convenient to connect the gas outlet pipes 243 to the compressor 201 while preventing interference between the gas outlet pipes 243 and the flow path integration module 100, which is beneficial to improving the assembly convenience of the air conditioning system 1000.

[0223] Combination Figures 9 to 13 In some embodiments of this utility model, the outer edge of the substrate 10 is partially recessed to form a second clearance opening 16 to avoid the gas outlet pipe 243.

[0224] For example, the gas outlet pipe 243 is connected to the suction port 2011 of the compressor 201. The outer edge of the substrate 10 near the compressor 201 can be recessed away from the substrate 10 to form a second clearance opening 16. When the gas outlet pipe 243 is connected to the suction port 2011 of the compressor 201, the substrate 10 can pass through the second clearance opening 16 to avoid the gas outlet pipe 243, preventing the gas outlet pipe 243 from interfering with the substrate 10 and affecting the assembly of the gas outlet pipe 243 and the flow path integration module 100. At the same time, there is no need to set up space outside the substrate 10 for arranging the gas outlet pipe 243, which is beneficial to improve the integration of the air conditioning system 1000 and reduce the volume of the air conditioning system 1000, realizing the miniaturization design of the air conditioning system 1000.

[0225] Combination Figure 12 , Figure 14 as well as Figure 17 In some embodiments of this utility model, the refrigerant circuit further includes an economizer 210. The economizer 210 has a first heat exchange flow path 2101 and a second heat exchange flow path 2102 that exchange heat with each other. The outlet of the first heat exchange flow path 2101 is connected to the gas supply port 2013 of the compressor 201. The second heat exchange flow path 2102 is connected between the high-pressure valve 204 and the first throttling element 205. The inlet of the first heat exchange flow path 2101 is connected between the second heat exchange flow path 2102 and the first throttling element 205 through the second throttling element 206.

[0226] For example, when it is necessary to replenish gas to compressor 201, the refrigerant passing through high-pressure valve 204 can flow into the second heat exchange flow path 2102. Part of the refrigerant flowing out of the second heat exchange flow path 2102 can flow into the first heat exchange flow path 2101 through the second throttling element 206. The refrigerant entering the first heat exchange flow path 2101 can exchange heat with the refrigerant in the second heat exchange flow path 2102 and absorb the temperature of the refrigerant in the second heat exchange flow path 2102. After heat exchange, the temperature of the refrigerant in the first heat exchange flow path 2101 rises and enters compressor 201 through the gas replenishment port 2013 of compressor 201 to replenish gas to compressor 201.

[0227] Meanwhile, another portion of the refrigerant flowing out of the second heat exchange path 2102 can flow to the first throttling element 205, and in this process, the refrigerant flowing to the first throttling element 205 can pass through the electronically controlled radiator 209 and dissipate heat for the electronically controlled module.

[0228] When there is no need to replenish the compressor 201 with gas, the second throttling element 206 can be closed to cut off the first heat exchange flow path 2101.

[0229] Combination Figure 12 and Figure 13In some examples, the orthographic projection of the economizer 210 on the substrate 10 is located within the outer contour of the substrate 10. That is, in the thickness direction of the substrate 10, the economizer 210 can be completely opposite to the substrate 10 to make full use of the space on one side of the substrate 10 in the thickness direction without occupying the space on at least one side of the substrate 10 in the first or second direction. This effectively improves the structural compactness of the air conditioning system 1000, reduces the volume of the air conditioning system 1000, and realizes the miniaturized design of the air conditioning system 1000.

[0230] Combination Figures 12 to 14 In other examples, the air conditioning system 1000 also includes a support plate 300, which includes a connecting portion 310 and a supporting portion 320 connected together. The connecting portion 310 is sandwiched between the base plate 10 and the separate body 241, and the supporting portion 320 supports the side of the economizer 210 away from the base plate 10.

[0231] For example, the connecting portion 310 and the supporting portion 320 are spaced apart in the thickness direction of the substrate 10. The connecting portion 310 is sandwiched between the substrate 10 and the separation body 241, and the connecting portion 310 can be connected to the substrate 10 and the separation body 241 respectively, so as to improve the connection reliability between the gas-liquid separator 240 and the flow path integration module 100.

[0232] The support portion 320 is located on the side of the connecting portion 310 away from the substrate 10 in the thickness direction, and the support portion 320 can be supported on the side surface of the economizer 210 away from the substrate 10. Since the connecting portion 310 is connected to the substrate 10 and the separation body 241 respectively, by having the support portion 320 connected to the connecting portion 310 support the economizer 210, it is beneficial to improve the assembly reliability of the economizer 210.

[0233] In some other examples, the orthographic projection of the economizer 210 on the substrate 10 is located within the outer contour of the substrate 10, and the air conditioning system 1000 also includes a support plate 300, which includes a connecting portion 310 and a supporting portion 320 connected together. The connecting portion 310 is sandwiched between the substrate 10 and the separation body 241, and the supporting portion 320 supports the side of the economizer 210 away from the substrate 10. This is beneficial to improving the integration of the air conditioning system 1000 and to realizing the miniaturization design of the air conditioning system 1000. It is also beneficial to improve the connection reliability between the gas-liquid separator 240 and the flow path integration module 100, and can also improve the assembly reliability of the economizer 210.

[0234] In some embodiments, the substrate 10, the connecting part 310 and the separating body 241 can be fixedly connected by a threaded connector 22 to facilitate the assembly and disassembly of the substrate 10, the connecting part 310 and the separating body 241.

[0235] The following is combined with Figure 12 and Figure 17 This describes the specific structure of the air conditioning system 1000 according to an embodiment of the present invention and the connection relationship between different components.

[0236] The air conditioning system 1000 includes a refrigerant circuit and a flow path integration module 100. The refrigerant circuit includes a compressor 201, a reversing valve 202, a low-pressure valve 203, an indoor heat exchanger, a high-pressure valve 204, a first throttling element 205, a second throttling element 206, a third throttling element 207, an outdoor heat exchanger 208, an economizer 210, and a gas-liquid separator 240. The flow path integration module 100 includes a base plate 10 and a flow path module 20. The flow path module 20 includes a first flow channel component 1, a second flow channel component 206, a third flow channel component 207, a third flow channel component 208, a third flow channel component 209, a fourth flow channel component 200, and a fifth flow channel component 200. The flow channel components 2, 3, 5, 6, 7, 8, and 9 are provided on the substrate 10. Four second channels are provided through the substrate 10 along its thickness direction. The first heat exchange flow path 2101 and the second heat exchange flow path 2102 of the economizer 210 have inlets and outlets respectively. The four second channels are provided and connected to the inlet and outlet of the first heat exchange flow path 2101 and the inlet and outlet of the second heat exchange flow path 2102.

[0237] The sixth flow channel 6 is disposed in the middle region of the orthographic projection surface of the substrate 10 in the thickness direction, and the sixth flow channel 6 is provided with an interface 212 at both ends in its extension direction. One of the two interfaces 212 is disposed in the direction away from the substrate 10 and is connected to the first valve port a of the reversing valve 202. One of the two interfaces 212 is disposed in the second direction towards the outer edge of the substrate 10 and is connected to the low-pressure valve 203. At the same time, the low-pressure valve 203 is connected to one end of the indoor heat exchanger.

[0238] The fifth flow channel 5 is spaced apart from the sixth flow channel 6 along the first direction, and the fifth flow channel 5 is located near the outer edge of the substrate 10 on one side in the first direction. The fifth flow channel 5 is provided with two interfaces 212. One of the two interfaces 212 is located along the second direction toward the outer edge of the substrate 10 and is connected to the high-pressure valve 204. At the same time, the high-pressure valve 204 is connected to the other end of the indoor heat exchanger. The other of the two interfaces 212 is located toward the substrate 10 and is connected to a second flow channel 14 that is connected to the second heat exchange flow path 2102.

[0239] The sixth flow channel 6 is provided with a seventh flow channel 7 on the side away from the fifth flow channel 5 in the first direction. The seventh flow channel 7 forms two first flow channels 211 and is provided with three interfaces 212. One of the three interfaces 212 is provided facing the substrate 10 and is connected to the second channel connected to the outlet of the second heat exchange flow path 2102. The other two of the three interfaces 212 are provided facing away from the substrate 10, and each interface 212 is provided corresponding to one of the first flow channels 211 in the seventh flow channel 7. One of the two interfaces 212 is connected to one end of the electronically controlled heat sink 209 and the other is connected to one end of the second throttling element 206. The seventh flow channel 7 is also provided with a third throttling element 207.

[0240] An eighth flow channel 8 is provided between the sixth flow channel 6 and the seventh flow channel 7. The eighth flow channel 8 is provided with two interfaces 212. One of the two interfaces 212 is arranged in a direction away from the substrate 10 and is connected to the other end of the second throttling element 206. The other of the two interfaces 212 is arranged in a direction away from the substrate 10 and is connected to a second flow channel 14 that is connected to the inlet of the first heat exchange flow path 2101.

[0241] A second flow channel 2 is provided between the sixth flow channel 6 and the fifth flow channel 5. The extension direction of the second flow channel 2 is the same as that of the sixth flow channel 6 and the fifth flow channel 5. Both ends of the second flow channel 2 are provided with interfaces 212 facing away from the substrate 10. One of the two interfaces 212 is connected to the other end of the electronically controlled heat sink 209, and the other of the two interfaces 212 is connected to one end of the first throttling element 205.

[0242] The end of the second flow channel 2 that is away from the electronically controlled radiator 209 is connected to the first flow channel 1. The first flow channel 1 extends in a direction perpendicular to the second flow channel 2 and away from the sixth flow channel 6.

The oil separator module 250 can separate the lubricating oil carried by the refrigerant discharged from the compressor 201. The separated lubricating oil can be collected in the oil separator 251 and sent back to the compressor 201. The refrigerant separated from the lubricating oil can flow to the reversing valve 202.

[0250] The following reference Figure 17 The following is a brief description of the two operating modes of the air conditioning system 1000 according to an embodiment of the present invention.

[0251] Heating mode: The first valve port a and the fourth valve port d of the reversing valve 202 are connected, and the second valve port b and the third valve port c are connected. The discharge port 2012 of the compressor 201 is connected to the fourth valve port d of the reversing valve 202. The high-temperature and high-pressure refrigerant discharged by the compressor 201 passes through the fourth valve port d and the first valve port a of the reversing valve 202, and then flows into the indoor heat exchanger through the low-pressure valve 203 to exchange heat with the indoor environment, thereby increasing the temperature of the indoor environment. After heat exchange, the temperature and pressure of the refrigerant decrease, and it further flows into the second heat exchange flow path 2102 through the high-pressure valve 204. After the second heat exchange flow path 2102, the refrigerant is split. A portion of the refrigerant flows to the electronically controlled radiator 209 to cool the electronic control device. The refrigerant passing through the electronically controlled radiator 209 further passes through the first throttling element 205, which throttles the refrigerant. Then, the refrigerant passes through the outdoor heat exchanger 208 and further through the second valve port b and the third valve port c of the reversing valve 202 before flowing into the gas-liquid separator 240. The gaseous refrigerant can flow through the gas outlet of the gas-liquid separator 240 into the suction port 2011 of the compressor 201 to facilitate the next heat exchange cycle.

[0252] Meanwhile, another portion of the refrigerant passing through the second heat exchange path 2102 flows into the first heat exchange path 2101 after passing through the third throttling element 207 and the second throttling element 206. The third throttling element 207 and the second throttling element 206 can throttle the refrigerant in sequence. After entering the first heat exchange path 2101, the refrigerant exchanges heat with the refrigerant in the second heat exchange path 2102 to increase the temperature of the refrigerant in the first heat exchange path 2101. Then, the refrigerant can further flow into the compressor 201 through the gas inlet 2013 of the compressor 201 to replenish the compressor 201.

[0253] Cooling mode: The fourth valve port d and the second valve port b of the reversing valve 202 are connected, the first valve port a and the third valve port c are connected, and the second throttling element 206 is closed. That is to say, the first heat exchange flow path 2101 is cut off, and the refrigerant will not flow into the first heat exchange flow path 2101. The high-temperature and high-pressure refrigerant discharged from the compressor 201 flows into the outdoor heat exchanger 208 after passing through the fourth valve port d and the second valve port b in sequence. After entering the outdoor heat exchanger 208, the refrigerant exchanges heat with the outdoor environment. After heat exchange, the temperature and pressure of the refrigerant decrease. Then, the refrigerant flows into the electronically controlled radiator 209 after passing through the first throttling element 205. In this process, the first throttling element 205 throttles the refrigerant. The temperature and pressure of the refrigerant are further reduced. After flowing into the electronically controlled radiator 209, the refrigerant cools the electronic control module. Then, the refrigerant flows into the second heat exchange path 2102 and can further flow into the indoor heat exchanger through the high-pressure valve 204 to exchange heat with the indoor environment and reduce the temperature of the indoor environment. After heat exchange, the refrigerant flows out of the indoor heat exchanger and passes through the low-pressure valve 203. The refrigerant flowing out of the low-pressure valve 203 flows into the gas-liquid separator 240 after passing through the first valve port a and the third valve port c, and gas-liquid separation is achieved. The separated gaseous refrigerant can flow back to the compressor 201 through the gas outlet pipe 243 and the suction port 2011 of the compressor 201 to facilitate the next heat exchange cycle.
