[0076] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where 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 drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0077] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "thickness", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In addition, the features defined with "first", "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise stated, the meaning of "a plurality" is two or more.

[0078] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0079] Next, refer to Figures 1 - 17 Describe the flow path integration module 100 and the air conditioning system 1000 according to the embodiments of the present invention.

[0080] As Figure 1 shown, for the flow path integration module 100 according to the embodiments of the present invention, the flow path integration module 100 is used for the air conditioning system 1000, and the flow path integration module 100 includes: a substrate 10 and a flow path module 20, and the flow path module 20 is provided on one side of the thickness of the substrate 10.

[0081] Exemplarily, the substrate 10 can serve as the installation carrier of the flow path module 20, facilitating the positioning and installation of the flow path module 20, thereby contributing to improving the installation convenience of the flow path integration module 100. For example, 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 integration module 100, the flow path integration module 100 can be positioned and installed through the substrate 10, eliminating the need to separately position and assemble the substrate 10 and the flow path module 20, and improving the installation convenience of the flow path integration module 100.

[0082] Combined with Figures 2 - 4 and Figure 7 and Figure 8 , the flow path module 20 includes flow channel members 21. There are multiple flow channel members 21 which are spaced apart. Each flow channel member 21 has a first flow channel 211 therein, and the first flow channel 211 has at least two interfaces 212.

[0083] Each first flow channel 211 can be respectively connected to different components of the air conditioning system 1000. For example, the air conditioning system 1000 can 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 respectively connected to the valves and the heat exchanger. For example: one interface 212 of this first flow channel 211 can be connected to the valves, and the other interface 212 of this first flow channel 211 can be connected to the heat exchanger, enabling 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 providing the flow path integration module 100, it is beneficial to eliminate the need to correspondingly arrange pipelines for different components of the air conditioning system 1000, simplify the pipeline arrangement of the air conditioning system 1000, reduce the production and processing costs of the air conditioning system 1000, and is beneficial to improving 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 facilitating reducing the layout space required for the air conditioning system 1000.

[0084] Combined with Figures 1 - 4 and Figure 7 , the flow path module 20 further includes a connecting member 22. The connecting member 22 is connected between two adjacent flow channel members 21, and the connecting member 22 is arranged to avoid the interfaces 212.

[0085] Exemplarily, two adjacent flow channel members 21 among the multiple flow channel members 21 are connected by one connecting member 22, and the connecting member 22 is arranged to avoid the interfaces 212 to prevent the connecting member 22 from blocking the interfaces 212 and ensuring the connection effect of the first flow channel 211.

[0086] By connecting the connecting member 22 between two adjacent flow channel members 21 to connect multiple flow channel members 21, it is convenient to achieve modular assembly of the flow path module 20, which is beneficial to improving the strength of the flow channel member 21. Specifically, the connecting member 22 can play a role in supporting the flow channel member 21, thereby achieving the improvement of the structural strength of the flow channel member 21, and being beneficial to the integration degree of the flow path module 20, and being beneficial to reducing the assembly difficulty of the flow path module 20 and improving the assembly efficiency of the flow path module 20. Consequently, it is beneficial to improve the integration degree of the flow path integration module 100, reduce the assembly difficulty of the flow path integration module 100, and at the same time, the production efficiency of the flow path integration module 100 can be improved.

[0087] Combined with Figures 1 - 4 and Figure 7 , wherein, the connecting member 22 is arranged at an interval from the substrate 10.

[0088] Exemplarily, in the thickness direction of the substrate 10, there is an interval between the side of the connecting member 22 facing the substrate 10 and the substrate 10. It can also be understood that the connecting member 22 and the substrate 10 are not coplanar, and there is no need to connect the connecting member 22 to the substrate 10, which is beneficial to reducing the processing difficulty and processing cost of the flow path integration module 100.

[0089] Considering that the temperatures of the refrigerants in the two first flow channels 211 connected by the same connecting member 22 may be different, then the refrigerants in the two first flow channels 211 connected by the same connecting member 22 may exchange heat through the connecting member 22. By arranging the connecting member 22 at an interval from the substrate 10, an air gap is formed between the connecting member 22 and the substrate 10, which is beneficial to increasing the contact area between the connecting member 22, the substrate 10 and the air. Furthermore, it is beneficial to the heat dissipation on the connecting member 22, beneficial to reducing the heat exchange between the two first flow channels 211 connected to the same connecting member 22, and thus beneficial to ensuring the performance of the air conditioning system 1000.

[0090] In the related art, the connection bridge of the integrated module is usually welded to the bottom plate, which means that there are high requirements for the flatness of the connection bridge and the bottom plate, resulting in high requirements for the processing accuracy of the integrated module and affecting the processing convenience of the integrated module. Moreover, due to the small contact area between the connection bridge and the air, the heat dissipation area of the connection bridge is small, resulting in easy heat exchange between the two flow channels connected to the connection bridge and affecting the working performance of the air conditioning system.

[0091] In this application, by providing the connecting member 22, multiple flow channel members 21 can be connected to form the flow path module 20, improving the integration degree of the flow path module 20 and reducing the assembly difficulty of the flow path module 20. By further spacing the connecting member 22 from the substrate 10 without connecting the connecting member 22 to the substrate 10, it is beneficial to reduce the processing difficulty and cost of the flow path integration module 100, and an air gap can be formed between the connecting member 22 and the substrate 10, which is conducive to increasing the contact area between the connecting member 22, the substrate 10 and the air, so as to increase the heat dissipation area of the connecting member 22, and is beneficial to reducing the heat exchange between the two first flow channels 211 connected to the same connecting member 22 through the connecting member 22, thus being beneficial to reducing the influence of the connecting member 22 on the working performance of the air conditioning system 1000.

[0092] In some embodiments, the flow path module 20 is connected to the substrate 10 by welding to improve the sealing performance of the first flow channel 211, and at the same time is beneficial to improving the connection strength between the flow path module 20 and the substrate 10, and further beneficial to improving the structural strength of the flow path integration module 100.

[0093] Among them, by spacing the connecting member 22 from the substrate 10, that is to say, the connecting member 22 does not need to be welded to the substrate 10, so as to reduce the requirements for the flatness of the connecting member 22 and the substrate 10, which is beneficial to reducing the processing precision requirements for the flow path integration module 100, and further beneficial to improving the production and processing efficiency of the flow path integration module 100. At the same time, the welding cost can be reduced, thus being beneficial to reducing the production and processing cost of the flow path integration module 100.

[0094] Combined with Figure 1 、 Figure 2 and Figure 13 , in some embodiments of the present invention, the orthographic projections of multiple flow channel members 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 members 21 are spaced apart on the substrate 10, that is to say, multiple flow channel members 21 do not overlap in the thickness direction of the substrate 10, and it can also be understood that multiple flow channel members 21 are respectively laid on the substrate 10, so as to facilitate the arrangement of multiple flow channel members 21 on the substrate 10 respectively, which is beneficial to improving the assembly convenience of multiple flow channel members 21. While achieving a reasonable distribution of the space on the substrate 10, it is beneficial to reduce the size of the flow path module 20 in the thickness direction of the substrate 10, thereby being beneficial to reducing the size of the flow path integration module 100 in the thickness direction of the substrate 10, and further beneficial to reducing the size of the air conditioning system 1000, realizing the miniaturized design of the air conditioning system 1000 and improving the assembly convenience of the air conditioning system 1000.

[0096] In some 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. It can also be understood that the flow path module 20 is provided on the substrate 10, and the area of the orthographic projection of the flow path module 20 is smaller than the area of the substrate 10, so as to ensure the supporting effect of the substrate 10 on the flow path module 20, improve the assembly convenience of the flow path module 20, and contribute to improving the stability of the flow path module 20.

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

[0098] In still some other examples, the orthographic projections of multiple flow channel members 21 are spaced on the substrate 10, and at the same time, 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 to say, multiple flow channel members 21 are laid on the substrate 10, and the area of the orthographic projection of the flow path module 20 is smaller than the area of the substrate 10, so as to achieve a reasonable allocation of the space on the substrate 10, reduce the size of the flow path module 20 in the thickness direction of the substrate 10, and contribute to further improving the assembly convenience and assembly stability of the flow path module 20.

[0099] Combined with Figures 2 - 4 and Figure 7 , in some embodiments of the present invention, the surface of at least one of two adjacent flow channel members 21 facing away from the substrate 10 and the surface of the corresponding connecting member 22 facing away from the substrate 10 are coplanar; and / or, there are multiple connecting members 22, and the surfaces of at least two connecting members 22 facing away from the substrate 10 are coplanar.

[0100] In some examples, the surface of at least one of two adjacent flow channel members 21 facing away from the substrate 10 and the surface of the corresponding connecting member 22 facing away from the substrate 10 are coplanar. For example, the surface of one of two adjacent flow channel members 21 facing away from the substrate Ⅰ0 and the surface of the corresponding connecting member 22 (which can also be understood as the connecting member 22 connected to it) facing away from the substrate 10 are in the same plane; or the surfaces of two adjacent flow channel members 21 facing away from the substrate 10 and the surfaces of the corresponding connecting members 22 (which can also be understood as the connecting members 22 connected to the two) facing away from the substrate 10 are in the same plane, which is conducive to improving the processing convenience of the flow path module 20. Specifically, when processing the flow channel members 21 and the connecting members 22, the number of preset height dimensions to be processed can be reduced, which is conducive to improving the processing convenience of the flow path module 20 and thus conducive to improving the production and processing efficiency of the flow path module 20.

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

[0102] In some other examples, the side surfaces of at least two of the plurality of connecting members 22 facing away from the substrate 10 are coplanar. For example, there can be four connecting members 22, and the side surfaces of two of the four connecting members 22 facing away from the substrate 10 are coplanar, or the side surfaces of three of the four connecting members 22 facing away from the substrate 10 are coplanar, or the side surfaces of all four connecting members 22 facing away from the substrate 10 are coplanar, so as to reduce the preset height dimension of the connecting members 22 to be processed, which is beneficial to improving the processing convenience of the flow path module 20, and thus beneficial to improving the production and processing efficiency of the flow path module 20.

[0103] In still some other examples, the side surface of at least one of two adjacent flow channel members 21 facing away from the substrate 10 is coplanar with the side surface of the corresponding connecting member 22 facing away from the substrate 10; there are a plurality of connecting members 22, and the side surfaces of at least two connecting members 22 facing away from the substrate 10 are coplanar. For example, the side surfaces of the plurality of flow channel members 21 facing away from the substrate 10 and the side surfaces of the plurality of connecting members 22 facing away from the substrate 10 are all coplanar, so that when processing the flow channel members 21 and the connecting members 22, only one height dimension needs to be set, so as to further improve the processing convenience of the flow path module 20, and thus beneficial to improving the production and processing efficiency of the flow path module 20.

[0104] Combined with Figure 1 、 Figure 7 、 Figure 9 and Figure 10 , in some embodiments of the present invention, each flow channel member 21 corresponds to at least one connecting member 22, and a positioning protrusion 11 protrudes from one side of the thickness of the substrate 10, and the positioning protrusion 11 abuts against the outer surface of the corresponding flow channel member 21.

[0105] It should be noted that the "outer surface of the flow channel member 21" can be understood as the side surfaces of the plurality of flow channel members 21 facing away from each other, or it can also be understood as the side surface of the flow channel member 21 away from the central position of the flow path module 20.

[0106] Exemplarily, any two adjacent flow channel members 21 among the multiple flow channel members 21 are connected by a connecting member 22. For example, the flow path module 20 may include three flow channel members 21 arranged in a straight line. In this case, the flow channel members 21 located on both sides can be respectively connected to the flow channel member 21 located in the middle through a connecting member 22. The flow path module 20 may include multiple flow channel members 21 arranged in a circular shape. In this case, any two adjacent flow channel members 21 can be connected by a connecting member 22. The connecting member 22 is arranged in an avoidance manner with respect to the interface 212 to prevent the connecting member 22 from blocking the interface 212 and ensure the communication effect of the first flow channel 211.

[0107] It can be understood that the number and arrangement mode of the above-mentioned flow channel members 21 are only examples given for the convenience of explanation and understanding, and should not be construed as a limitation to this application. The number and arrangement mode of the flow channel members 21 can be determined according to actual production requirements and are not specifically limited herein.

[0108] On one surface of the substrate 10 facing the flow path module 20 in the thickness direction, positioning protrusions 11 are provided. The positioning protrusions 11 protrude in a direction away from the substrate 10. The positioning protrusions 11 can be in abutting fit with the outer surface of the flow channel member 21, so that the flow path module 20 can be positioned and installed on the substrate 10 through the positioning protrusions 11, which is beneficial to improving the assembly convenience of the flow path module 20.

[0109] Combined Figure 1 、 Figure 7 、 Figure 9 and Figure 10 , in some embodiments of the present invention, 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 arranged at intervals in a direction perpendicular to the thickness direction of the substrate 10, and the opposite sides of the two facing each other 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] Exemplarily, the first positioning protrusion 111 and the second positioning protrusion 112 may be arranged at intervals along the length direction of the substrate 10, or the first positioning protrusion 111 and the second positioning protrusion 112 may be arranged at intervals along the width direction of the substrate 10. One side of the first positioning protrusion 111 facing the second positioning protrusion 112 is recessed in a direction away from the second positioning protrusion 112. Correspondingly, one side of the second positioning protrusion 112 facing the first positioning protrusion 111 is recessed in a direction away from the first positioning protrusion 111. At least a part of the flow path module 20 may 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 may be in abutting fit with the first positioning protrusion 111 and the second positioning protrusion 112 respectively, and the first positioning protrusion 111 and the second positioning protrusion 112 may limit the flow path module 20 in a direction perpendicular to the recess and perpendicular to the thickness direction of the substrate 10, thereby realizing the positioning and installation of the flow path module 20 on the substrate 10 and being beneficial to 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 opposite and arranged at intervals in a direction perpendicular to the thickness direction of the substrate 10. For example, the first positioning protrusion 111 and the second positioning protrusion 112 may be opposite and arranged at intervals in the width direction of the substrate 10. One of the plurality of flow channel members 21 of the flow path module 20 may be in abutting fit with the first positioning protrusion 111 and the second positioning protrusion 112 respectively to realize the positioning and installation of the flow path module 20 on the substrate 10.

[0113] In other examples, the first positioning protrusion 111 and the second positioning protrusion 112 may be offset and arranged at intervals in a direction perpendicular to the thickness direction of the substrate. For example, the first positioning protrusion 111 and the second positioning protrusion 112 may be arranged at intervals in the width direction of the substrate 10, and the first positioning protrusion 111 and the second positioning protrusion 112 may be offset in the length direction of the substrate 10. One of the plurality of flow channel members 21 of the flow path module 20 may be in abutting fit with the first positioning protrusion 111, and another one of the plurality of flow channel members 21 may be in abutting fit with the second positioning protrusion 112 to realize the positioning and installation of the flow path module 20 on the substrate 10.

[0114] It can be understood that the specific arrangement positions of the first positioning protrusion 111 and the second positioning protrusion 112 may be determined according to actual production requirements and are not specifically limited herein.

[0115] Combined with Figures 1 - 4 and Figures 9 - 11, in some embodiments of the present invention, one side surface of each flow channel member 21 facing the substrate 10 is respectively fixed to the substrate 10, and one side surfaces of a plurality of flow channel members 21 facing the substrate 10 are coplanar, and one 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] Combined with Figures 1 - 4 , in some examples, one side surface of each flow channel member 21 facing the substrate 10 is respectively fixed to the substrate 10, and one side surfaces of a plurality of flow channel members 21 facing the substrate 10 are coplanar, and one side surface of the substrate 10 facing the flow path module 20 is a plane. By making one side surfaces of a plurality of flow channel members 21 facing the substrate 10 coplanar and configuring one side surface of the substrate 10 facing the flow path module 20 as a plane, it is convenient to weld the flow channel members 21 to the substrate 10, and it is beneficial to ensure the blocking effect of the substrate 10 on the first flow channel 211 formed by the flow channel members 21, and reduce the risk of refrigerant leakage between the substrate 10 and the flow channel members 21.

[0117] Combined with Figures 9 - 11 In other examples, the substrate 10 is configured 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 supporting effect of the substrate 10 on the flow path module 20, and reduce the risk of damage to the substrate 10, thereby being beneficial to improving 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 members 21 provided on the substrate 10 can be increased, so that more flow channel members 21 can be provided on the substrate 10 to further improve the integration degree of the flow path integration module 100.

[0118] It can be understood that the thickness of the substrate 10 can be 2 mm, 2.5 mm, 2.6 mm, 3 mm, etc. The specific thickness of the substrate 10 can be determined according to actual production requirements and will not be specifically limited here.

[0119] In still other examples, one side surface of each flow channel member 21 facing the substrate 10 is respectively fixed to the substrate 10, and one side surfaces of a plurality of flow channel members 21 facing the substrate 10 are coplanar, and one side surface of the substrate 10 facing the flow path module 20 is a plane. At the same time, the substrate 10 is configured as a flat plate, and the thickness of the substrate 10 is greater than or equal to 2 mm to improve the processing convenience of the substrate 10, facilitate the connection of the flow channel members 21 to the substrate 10, and at the same time be beneficial to ensuring the blocking effect of the substrate 10 on the first flow channel 211 formed by the flow channel members 21, and can improve the structural strength of the substrate 10, improve the supporting effect of the substrate 10 on the flow path module 20, and reduce the risk of damage to the substrate 10, thereby being beneficial to improving the service life of the flow path integration module 100.

[0120] Combined withFigure 1 and Figure 7 In some embodiments of the present invention, the flow path integration module 100 further includes a welding ring 23. The welding ring 23 is integrally connected to the interface 212 disposed corresponding to the side facing away from the substrate 10, and protrudes from the surface of the corresponding flow channel member 21 on the side facing away from the substrate 10 in the direction away from the substrate 10. The welding ring 23 is adapted to be inserted and welded with the corresponding pipeline, and the axial height of the welding ring 23 is greater than or equal to 5 mm.

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

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

[0123] In other embodiments, the welding ring 23 can be separately provided from the flow channel member 21, and the welding ring 23 can be fixedly installed at the interface 212 disposed corresponding to the side facing away from the substrate 10 through connection means such as welding.

[0124] In a further embodiment of the present invention, 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 mating reliability between the welding ring 23 and the corresponding pipeline, and at the same time, it is beneficial to reduce the material consumption of the welding ring 23, thereby being beneficial to reducing the production and processing cost of the flow path integration module 100.

[0125] Wherein, when the axial height of the welding ring 23 is less than 5 mm, the axial height of the welding ring 23 is too small, the insertion reliability between the transition pipe 230 and the welding ring 23 is poor, and it will result in a small contact area between the transition pipe 230 and the welding ring 23, thereby affecting the connection strength between the transition pipe 230 and the welding ring 23; when the axial height of the welding ring 23 is greater than 15 mm, the axial height of the welding ring 23 is too large, resulting in excessive material consumption of the welding ring 23 and increasing the material cost of the flow path module 20.

[0126] Combined with Figure 1 and Figure 7, in some embodiments of the present invention, the multiple interfaces 212 of the flow path module 20 include a first interface and a second interface. The first interface is arranged towards the outer edge of the substrate 10 along the second direction 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 arranged facing away from the substrate 10.

[0127] It should be noted that the "first direction" can be understood as the length direction of the substrate 10 described above, and the "second direction" can be understood as the width direction of the substrate 10. For a specific direction illustration, reference can be made to Figure 1 or Figure 2 as shown.

[0128] Exemplarily, the first interface can be arranged towards the outer edge of the substrate 10 along the second direction. There can be one first interface, and one first interface can be connected to the low-pressure valve 203 or the high-pressure valve 204 of the air-conditioning system 1000. Or there can be two first interfaces. One of the two first interfaces is connected to the low-pressure valve 203 of the air-conditioning system 1000, and the other of the two first interfaces is connected to the high-pressure valve 204. The second interface is arranged facing away from the substrate 10. The second interface can be used to be connected to other components of the air-conditioning system 1000 (such as the throttle element or the reversing valve 202 described below). By making the opening directions of the first interface and the second interface different, it is convenient to stagger the low-pressure valve 203 or the high-pressure valve 204 of the air-conditioning system 1000 from other components, reduce 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, improve the integration degree of the air-conditioning system 1000, and at the same time, is beneficial to improving the assembly convenience of the air-conditioning system 1000.

[0129] Combined with Figure 1 、 Figure 7 、 Figure 9 、 Figure 1 and ​ , at least one first interface is respectively provided with other flow path members 21 on both sides in the first direction. A first avoidance through hole 13 is formed on the substrate 10. The first avoidance through hole 13 is opposite to the first interface and penetrates through the substrate 10 along the thickness direction of the substrate 10. The first direction, the second direction and the thickness direction of the substrate 10 are perpendicular to each other in pairs.

[0130] Since other flow path members 21 are respectively provided on both sides of at least one first interface in a first direction, when the first interface is welded and connected to the low-pressure valve 203 or the high-pressure valve 204, the other flow path members 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, resulting in poor convenience in welding the first interface to the high-pressure valve 204 or the low-pressure valve 203, and it is not convenient to inspect the welding quality at the first interface. By forming a first avoidance through-hole 13 on the substrate 10 that penetrates the substrate 10 along the thickness direction of the substrate 10, and the first avoidance through-hole 13 is oppositely arranged with the first interface where other flow path members 21 are respectively provided on both sides in the first direction, it is convenient to deliver solder to the first interface where other flow path members 21 are respectively provided on both sides in the first direction through the first avoidance through-hole 13, improving the welding convenience between the first interface and the low-pressure valve 203 or the high-pressure valve 204, and it is convenient to inspect the welding quality at the first interface through the first avoidance through-hole 13.

[0131] Combined with ​ and ​ In some embodiments of the present invention, there are two first interfaces. One of the first interfaces is adapted to be connected to the low-pressure valve 203, and other flow path members 21 are respectively provided on both sides of it in the first direction. The other first interface is adapted to be connected to the high-pressure valve 204, and other flow path members 21 are provided on one of the two sides of it in the first direction.

[0132] Exemplarily, the two first interfaces can be spaced apart in the first direction. The first interface connected to the low-pressure valve 203 is respectively provided with flow path members 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 a flow path member 21 connected to other components of the air-conditioning system 1000 on one of the two sides in the first direction. For example, the first interface connected to the high-pressure valve 204 can be arranged at the outer edge of the substrate 10 in the first direction. A part of the flow path members 21 is arranged 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, and another part of the flow path members 21 can be arranged between the two first interfaces to improve the structural compactness of the flow path module 20, which is beneficial to reducing the volume of the flow path module 20, and thus beneficial to reducing the volume of the flow path integration module 100 and improving the integration degree of the flow path integration module 100.

[0133] Combined with ​ and ​ In some embodiments of the present invention, the cross-sectional shape of the connecting member 22 is polygonal, circular or elliptical; or, at least one side of the connecting member 22 in the thickness direction of the substrate 10 is formed with a groove 221, and the width of the groove 221 is smaller than the width of the connecting member 22.

[0134] In some examples, in the thickness direction parallel to the substrate 10, the cross-sectional shape of the connector 22 can be a polygon such as a square, pentagon, or hexagon, or the cross-sectional shape of the connector 22 can also be a circle or an ellipse, etc. It can be understood that the specific cross-sectional shape of the connector 22 can be determined according to actual production requirements and is not specifically limited here.

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

[0136] Combine ​ and ​ In other examples, a groove 221 is formed on at least one side wall of the connecting member 22 extending along its length direction, and the groove 221 passes through both ends of the connecting member 22 along the length direction of the connecting member 22, and the width of the groove 221 is smaller than the width of the connecting member 22.

[0137] For example, the connector 22 can extend along a first direction, then the first direction is the length direction of the connector 22, the groove 221 and the width direction of the connector 22 are perpendicular to the first direction and the thickness direction of the substrate 10, and the side wall of the connector 22 facing the substrate 10 can be set in a groove 221 that is recessed in the 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 a U-shape or an L-shape. Specifically, when the groove 221 is set in the middle position of the connector 22 in the width direction, the cross-section of the connector 22 can be formed as a U-shape; when the groove 221 is set on one side of the width direction of the connector 22, the cross-section of the connector 22 can be formed as an L-shape.

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

[0139] It can be understood that the arrangement of the above-mentioned groove 221 on the side wall of the connecting part 22 facing the substrate 10 or the side wall facing away from the substrate 10 is only an example of the present application. The groove 221 can also be arranged on the wall of the connecting part 22 perpendicular to the substrate 10. The specific setting position of the groove 221 can be determined according to actual production requirements and is not specifically limited here.

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

[0141] Combined with ​ , in some embodiments of the present invention, the cross-sectional area of the connecting member 22 is less than or equal to the minimum cross-sectional area of the corresponding flow channel member 21.

[0142] It should be noted that the "cross-sectional area of the flow channel member 21" can be understood as the cross-sectional area of the flow channel member 21 in the direction perpendicular to the extension direction of the first flow channel 211 it has, or it can be understood as the cross-sectional area of the flow channel member 21 in the direction perpendicular to the flow direction of the refrigerant within the flow channel member 21. The "minimum cross-sectional area of the flow channel member 21" does not include the cross-sectional area of the first flow channel 211 it has. That is to say, the "minimum cross-sectional area of the flow channel member 21" refers to the cross-sectional area of the physical structure of the "flow channel member 21".

[0143] Exemplarily, the connecting member 22 can extend along the first direction, and the end of the connecting member 22 in the first direction is connected to the flow channel member 21. The cross-sectional area of the connecting member 22 in the direction parallel to the thickness direction of the substrate 10 is less than or equal to the minimum cross-sectional area of the flow channel member 21 connected thereto, so as to reduce the heat exchange between the two flow channel members 21 connected to the connecting member 22, which is beneficial to improving the performance of the air conditioning system 1000.

[0144] In some embodiments of the present invention, the cross-sectional area of the connecting member 22 is greater than one-half of the minimum cross-sectional area of the corresponding flow channel member 21, so as to ensure the structural strength of the connecting member 22, which is beneficial to reducing the risk of damage to the flow path module 20 caused by damage to the connecting member 22. And since the connecting member 22 can be supported between the two flow channel members 21 correspondingly arranged, ensuring the structural strength of the connecting member 22 is beneficial to improving the support effect of the connecting member 22 on the two flow channel members 21 correspondingly arranged.

[0145] Combined with ​ , ​ , ​ , ​ and ​ , in some embodiments of the present invention, 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. The plurality of flow channel members 21 include a first flow channel member 1 and a second flow channel member 2. The first flow channel member 1 and the second flow channel member 2 are adapted to be correspondingly connected to the two ends of the first throttling element 205 respectively, and the first flow channel member 1 and the second flow channel member 2 are adjacent and connected by the connecting member 22.

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

[0147] Combined with ​ 、 ​ 、 ​ 、 ​ and ​ In other examples, the multiple flow path members 21 include a third flow path member 3 and a fourth flow path member 4. The third flow path member 3 and the fourth flow path member 4 are respectively and correspondingly connected to two ends of the outdoor heat exchanger 208. The third flow path member 3 and the fourth flow path member 4 are adjacent and connected through the connecting member 22.

[0148] For example, the third flow path member 3 can be connected to one end of the outdoor heat exchanger 208, and the fourth flow path member 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 path member 4 and exchange heat with the external environment. The refrigerant after heat exchange can flow into the third flow path member 3 from the outdoor heat exchanger 208. The third flow path member 3 and the fourth flow path member 4 are arranged adjacent to each other, so as to facilitate the connection of the third flow path member 3 and the fourth flow path member 4 to the outdoor heat exchanger 208 respectively, and facilitate the connection of the third flow path member 3 and the fourth flow path member 4 through the connecting member 22. At the same time, since the connecting member 22 is arranged at an interval from the substrate 10, the heat exchange between the third flow path member 3 and the fourth flow path member 4 through the connecting member 22 can be effectively reduced. Therefore, it is beneficial to improve the integration degree of the flow path module 20 while reducing the influence on the performance of the air conditioning system 1000 caused by heat exchange between the flow path members 21 through the connecting member 22.

[0149] Combined with ​ 、 ​ 、 ​ 、 ​ and ​, in some other examples, the multiple flow channel members 21 include a first flow channel member 1, a second flow channel member 2, a third flow channel member 3, and a fourth flow channel member 4. The first flow channel member 1 and the second flow channel member 2 are adapted to be respectively and correspondingly connected to the two ends of the first throttling element 205. The first flow channel member 1 and the second flow channel member 2 are adjacent and connected by a connecting member 22. The third flow channel member 3 and the fourth flow channel member 4 are adapted to be respectively and correspondingly connected to the two ends of the outdoor heat exchanger 208. The third flow channel member 3 and the fourth flow channel member 4 are adjacent and connected by a connecting member 22.

[0150] For example, one of the first flow channel member 1 and the second flow channel member 2 can be connected to one end of the first throttling element 205, and the other of the first flow channel member 1 and the second flow channel member 2 can be connected to the other end of the first throttling element 205. The third flow channel member 3 can be connected to one end of the outdoor heat exchanger 208, and the fourth flow channel member 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 member 1, the second flow channel member 2, the third flow channel member 3, and the fourth flow channel member 4 can be simplified into one. For example: the second flow channel member 2 can be connected to the inlet of the first throttling element 205, the first flow channel member 1 can be connected to the outlet of the first throttling element 205, the fourth flow channel member 4 can be connected to the inlet of the outdoor heat exchanger 208, and the third flow channel member 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. Then, at this time, only the first flow channel member 1 or the fourth flow channel member 4 can be used to realize the communication between the first throttling element 205 and the outdoor heat exchanger 208, effectively simplifying the number of the flow channel members 21, thereby facilitating the simplification of the structure of the flow path module 20 and improving the integration degree of the flow path module 20 to realize the improvement of the integration degree of the flow path integration module 100.

[0151] As ​ shown, in some embodiments of the present invention, the interfaces 212 of all the flow channel members 21 avoid the substrate 10.

[0152] Exemplarily, when the components of the air-conditioning system 1000 can be communicated only through the first flow channel 211 of the flow path module 20, the interfaces 212 of all the flow channel members 21 can avoid the substrate 10. For example, the interface 212 can be arranged in a direction away from the substrate 10, or the interface 212 can be arranged in a direction perpendicular to the thickness direction of the substrate 10 (such as the first direction or the second direction) to realize that the interfaces 212 of all the flow channel members 21 avoid the substrate 10, prevent the substrate 10 from blocking the interface 212, and facilitate the communication between the components of the air-conditioning system 1000 and the interface 212.

[0153] Or, in combination with ​, the substrate 10 has at least one second flow channel 14 therein. The second flow channel 14 penetrates through the substrate 10, and a first external interface 141 is formed on one surface of the second flow channel 14 facing away from the flow path module 20. The multiple interfaces 212 of the flow path module 20 include a second external interface and an internal interface. The second external interface is arranged to avoid the substrate 10, and the internal interface is arranged facing the substrate 10 and is communicated with the corresponding first external interface 141.

[0154] Exemplarily, 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 arranged on one side of the substrate 10 facing away from the flow path module 20. The substrate 10 is provided with a second flow channel 14 penetrating through it along its thickness direction, and a first external interface 141 is formed on one side of the second flow channel 14 facing away from the flow path module 20. The first external interface 141 can be used to connect to the component arranged on one side of the substrate 10 facing away from the flow path module 20. Correspondingly, the flow path module 20 is formed with an internal interface arranged facing the substrate 10, and the internal interface is communicated with the corresponding first external interface 141, so that the component arranged on one side of the substrate 10 facing away from the flow path module 20 can be communicated with the flow path integration module 100.

[0155] The flow path module 20 is further formed with a second external interface. The second external interface can be arranged to face away from the substrate 10 or perpendicular to the thickness direction of the substrate 10 to realize the arrangement of the second external interface avoiding the substrate 10. The second external interface can be used to connect to the component of the air-conditioning system 1000 located on one 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 in its thickness direction, so as to improve the integration degree of the air-conditioning system 1000 while reasonably allocating the installation positions of the components of the air-conditioning system 1000 connected to the flow path integration module 100.

[0156] Refer to ​ , in some embodiments of the present invention, the multiple flow path members 21 include a first flow path member 1, a second flow path member 2, a fifth flow path member 5, and a sixth flow path member 6. The interfaces 212 of the first flow path member 1, the second flow path member 2, and the sixth flow path member 6 all avoid the substrate 10. At least one interface 212 of the fifth flow path member 5 avoids the substrate 10. The first flow path member 1 is adapted to be connected between the outdoor heat exchanger 208 and the first throttling element 205. Both the second flow path member 2 and the fifth flow path member 5 are adapted to be connected between the first throttling element 205 and the high-pressure valve 204. The sixth flow path member 6 is adapted to be connected between the reversing valve 202 and the low-pressure valve 203.

[0157] Exemplarily, the first flow channel member 1 may be provided with two interfaces 212, both of the two interfaces 212 are arranged 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 member 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 member 5 may be provided with two interfaces 212. One of the two interfaces 212 may be arranged along an avoidance of the substrate 10 and connected to the high-pressure valve 204, and the other of the two interfaces 212 may be connected to the interface 212 of the second flow channel member 2 that is indirectly connected to the high-pressure valve 204, thereby realizing that both the second flow channel member 2 and the fifth flow channel member 5 are connected between the first throttling element 205 and the high-pressure valve 204; the sixth flow channel member 6 may be provided with two interfaces 212. One of the two interfaces 212 may be arranged away from the substrate 10, and the other of the two interfaces 212 may be arranged along the thickness direction perpendicular to the substrate 10. The interface 212 of the sixth flow channel member 6 arranged away from the substrate 10 may be connected to the reversing valve 202, and the interface 212 of the sixth flow channel member 6 arranged along the thickness direction perpendicular to the substrate 10 may be connected to the reversing valve 202.

The second flow channel member 2 and the fifth flow channel member 5 are arranged at intervals on one side of the first flow channel member 1 in the second direction, and they are opposite to each other along the first direction. A connecting member 22 is respectively provided between each of the second flow channel member 2 and the fifth flow channel member 5 and the first flow channel member 1. Thus, it is beneficial to improve the integration degree of the flow path module 20, reduce the volume of the flow path module 20, and thus be beneficial to improving the integration degree of the flow path integration module 100 to reduce the volume of the flow path integration module 100.

[0159] In addition, the interface 212 of the sixth flow channel member 6 adapted to be connected to the low-pressure valve 203 and the interface 212 of the fifth flow channel member 5 adapted to be connected to the high-pressure valve 204 are both arranged along the second direction towards the outer edge of the substrate 10, and their central axes are parallel. The first direction, the second direction and the thickness direction of the substrate 10 are perpendicular to each other in pairs.

[0160] By arranging the interface 212 of the sixth flow channel member 6 connected to the low-pressure valve 203 and the interface 212 of the fifth flow channel member 5 connected to the high-pressure valve 204 both along the second direction towards 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 mutual interference between the high-pressure valve 204 and the low-pressure valve 203 and the components arranged on one side in the thickness direction of the substrate 10, and improve the assembly convenience of the air-conditioning system 1000.

[0161] By making the central axes of the interface 212 of the sixth flow path member 6 connected to the low-pressure valve 203 and the interface 212 of the fifth flow path member 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, and at the same time, it is beneficial to avoid the settings of the low-pressure valve 203 and the high-pressure valve 204 occupying too much space on the flow path integration module 100, resulting in an increase in the volume of the flow path integration module 100.

The third flow path member 3 is spaced on the other side of the first flow path member 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 path member 3 and the first flow path member 1, and the interfaces 212 of the third flow path member 3 are all arranged to avoid the substrate 10.

[0163] Exemplarily, the third flow path member 3 is arranged on the side of the first flow path member 1 away from the second flow path member 2 and the fifth flow path member 5 in the second direction, and the third flow path member 3 can be connected to the first flow path member 1 through the connecting member 22 to improve the integration degree of the flow path module 20. Among them, the third flow path member 3 can be provided with two interfaces 212 arranged 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 to the reversing valve 202 through the third flow path member 3.

[0164] Combined with ​ 、 ​ and ​In some embodiments of the present invention, the air conditioning system 1000 includes a compressor 201 and an economizer 210.

[0170] Combine ​ 、 ​ and ​ In some embodiments of the present invention, the seventh runner member 7 and the eighth runner member 8 are both spaced apart on a side of the sixth runner member 6 away from the first runner member 1, and opposite sides of the eighth runner member 8 are respectively connected to the sixth runner member 6 and the seventh runner member 7 via connecting members 22. The ninth runner member 9 is spaced apart between the first runner member 1 and the fifth runner member 5, and opposite sides of the ninth runner member 9 are respectively connected to the first runner member 1 and the fifth runner member 5 via connecting members 22.

[0171] Exemplarily, the first flow channel member 1 is disposed on one side of the sixth flow channel member 6 in the first direction through the connecting member 22. Then, the seventh flow channel member 7 and the eighth flow channel member 8 can be disposed on the side of the sixth flow channel member 6 away from the first flow channel member 1 in the first direction. The two opposite sides of the eighth flow channel member 8 in the first direction are respectively connected to the sixth flow channel member 6 and the seventh flow channel member 7 through the connecting member 22. In the second direction, the ninth flow channel member 9 is disposed between the first flow channel member 1 and the fifth flow channel member 5, and the two opposite sides of the ninth flow channel member 9 in the second direction are respectively connected to the first flow channel member 1 and the fifth flow channel member 5 through the connecting member 22.

[0172] Thus, by providing a plurality of connecting members 22, the first flow channel member 1, the second flow channel member 2, the fifth flow channel member 5, the sixth flow channel member 6, the seventh flow channel member 7, the eighth flow channel member 8, and the ninth flow channel member 9 can be connected as a whole to improve the integration degree of the flow path module 20 and is conducive to improving the assembly efficiency of the flow path module 20.

[0173] In some specific embodiments, when the air-conditioning system 1000 is in the cooling mode, the first throttling element 205 is in the fully open state and the second throttling element 206 is closed. At this time, the temperature of one of the two first flow channels 211 respectively 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 the heating mode, before the first throttling element 205 throttles the refrigerant, the temperature of one of the two first flow channels 211 respectively 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 first throttling element 205 throttles the refrigerant, the temperature of one of the two first flow channels 211 respectively connected to both ends of the first throttling element 205 can be 5°C, and the temperature of the other can be 15°C; meanwhile, the second throttling element 206 operates. Before the second throttling element 206 throttles the refrigerant, the temperature of one of the two first flow channels 211 respectively 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 respectively 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] Thus, the temperature difference between the first flow channel member 1 and the second flow channel member 2 connected to both ends of the first throttling element 205 is small, and the temperature difference between the seventh flow channel member 7 and the eighth flow channel member 8 connected to both ends of the second throttling element 206 is small. Therefore, connecting the first flow channel member 1 and the second flow channel member 2 through the connecting member 22 and connecting the seventh flow channel member 7 and the eighth flow channel member 8 through the connecting member 22 have little influence on the heat transfer between the flow channel members 21.

The outdoor heat exchanger 208 and the reversing valve 202 can be connected through the flow channel member 21 provided therebetween, so that the refrigerant can flow between the outdoor heat exchanger 208 and the reversing valve 202.

[0185] It can be understood that the number of the flow channel members 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 member 21 is connected between the outdoor heat exchanger 208 and the reversing valve 202.

[0186] In some examples, the air-conditioning system 1000 can separately meet Condition A1 or Condition A2 or Condition A3 or Condition A4; in some other examples, the air-conditioning system 1000 can meet any two of Conditions A1 to A4; in still some other examples, the air-conditioning system 1000 can meet any three of Conditions A1 to A4; in some other examples, the air-conditioning system 1000 can meet all of Conditions A1 to A4.

[0187] It is understandable that the specific conditions satisfied by the air-conditioning system 1000 can be determined according to actual production requirements and will not be specifically limited here, as long as it is ensured that the refrigerant circuit of the air-conditioning system 1000 can be connected through the flow path integration module 100.

[0188] In the air-conditioning system 1000 according to the embodiment of the present invention, since the air-conditioning system 1000 includes the above-mentioned flow path integration module 100, by providing the connecting member 22, a plurality of flow path members 21 can be connected to form the flow path module 20, improving the integration degree of the flow path module 20 and reducing the assembly difficulty of the flow path module 20. By further arranging the connecting member 22 at an interval from the substrate 10 without connecting the connecting member 22 to the substrate 10, it is beneficial to reduce the processing difficulty and processing cost of the flow path integration module 100, and an air gap can be formed between the connecting member 22 and the substrate 10, which is conducive to increasing the contact area between the connecting member 22 and the substrate 10 and the air, so as to increase the heat dissipation area of the connecting member 22, and is beneficial to reducing the heat exchange of the two first flow paths 211 connected to the same connecting member 22 through the connecting member 22, thereby being beneficial to reducing the influence of the connecting member 22 on the working performance of the air-conditioning system 1000.

Whether the air-conditioning system 1000 is in the refrigeration mode or the heating mode, the temperature of the refrigerant flowing to the electric control radiator 209 is reduced. Therefore, when the refrigerant flows into the electric control radiator 209, heat exchange can be carried out on the electric control device, improving the heat dissipation efficiency of the electric control device.

[0195] An internal interface is provided on the side of the seventh flow channel component 7 facing the substrate 10, and the internal interface of the seventh flow channel component 7 can be connected to the first external interface 141 connected to the inlet of the second flow heat exchange path. At the same time, two second external interfaces set at intervals from each other are provided on the side of the seventh flow channel component 7 facing away from the substrate 10. Specifically, two first flow channels 211 can be formed in the seventh flow channel component 7, and the two first flow channels 211 can extend in different directions, so that the refrigerant flowing into the seventh flow channel component 7 from the second heat exchange path 2102 can be diverted in the seventh flow channel component 7.

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

[0198] Combine ​ and ​ In some embodiments of the present invention, a third throttling element 207 is provided in the seventh flow channel component 7. The third throttling element 207 is provided in the first flow channel 211 connected to the second throttling element 206 in the seventh flow channel component 7, and 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 the present invention, 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 valve 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 where it is located can be adjusted by selectively screwing the spiral throttling pin into or out of the first flow channel 211, so as to adjust the flow rate and pressure of the refrigerant in the first flow channel 211.

[0200] Combined with ​ and ​ , in some embodiments of the present invention, the refrigerant circuit includes at least one filter element provided 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, and the filter element may be provided at the interface 212 of the high-pressure valve 204, or the filter element may be provided at the interface 212 of the outdoor heat exchanger 208; in other examples, the refrigerant circuit may include two filter elements, one of the two filter elements may be provided at the interface 212 of the high-pressure valve 204, and the other of the two filter elements may be provided at the interface 212 of the outdoor heat exchanger 208.

[0202] By providing the filter element, the refrigerant can be filtered by the filter element during the flow process, so as to reduce the risk that the impurities carried by the refrigerant block the high-pressure valve 204 or the outdoor heat exchanger 208, which is beneficial to improving the service life of the air-conditioning system 1000.

[0203] As ​ shown, in some specific embodiments of the present invention, the filter element includes a mounting flange 2201 and a filter net 2202, and the filter net 2202 can be installed at the corresponding interface 212 through the mounting flange 2201.

[0204] In some embodiments of the present invention, the filter element 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 is welded to the corresponding interface 212 of the substrate 10 and each component of the air-conditioning system 1000 (such as the outdoor heat exchanger 208, the high-pressure valve 204, the low-pressure valve 203, etc.) and the flow path integration module 100.

[0205] Among them, combined with ​ and ​ , transition pipes 230 can be provided at the interfaces 212 provided on the side of the flow path module 20 facing away from the substrate 10, and are connected to the corresponding components through the transition pipes 230. After the positioning and installation of each component and the flow path integration module 100 are completed, each component can be welded to the corresponding transition pipe 230 along the direction from the central position of the flow path integration module 100 to the outer edge of the substrate 10.

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

[0207] Combined with ​ and ​ , in some embodiments of the present invention, there are multiple filter elements and they include: 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 member 21 located between the first throttling element 205 and the outdoor heat exchanger 208. The refrigerant circuit further includes an electronic control radiator 209. The air-conditioning system 1000 further includes an electronic control device. The electronic control radiator 209 is connected between the high-pressure valve 204 and the first throttling element 205 and is in heat conduction cooperation with the electronic control device. The second filter element 2204 is connected in series between the electronic control radiator 209 and the first throttling element 205. The third filter element 2205 is connected in series at one end of the electronic control radiator 209 away from the first throttling element 205.

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

[0209] Two interfaces 212 are provided on the second flow channel member 2. 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 electronic control radiator 209. At the same time, the electronic control radiator 209 can be connected to the second heat exchange flow path 2102 through the seventh flow channel member 7. And since the second heat exchange flow path 2102 can be connected to the high-pressure valve 204 through the fifth flow channel member 5, it can be realized that the electronic control radiator 209 is connected between the high-pressure valve 204 and the first throttling element 205. Among them, the second filter element 2204 can be provided at the interface 212 of the seventh flow channel member 7 connected to the electronic control radiator 209, and the third filter element 2205 can be provided at the interface 212 of the fifth flow channel member 5 connected to the high-pressure valve 204.

[0210] Thus, by respectively providing the first filter element 2203, the second filter element 2204, and the third filter element 2205, the impurities carried by the refrigerant when entering each component are reduced, which is beneficial to improving the service life of the air-conditioning system 1000.

[0211] Combined with ​ , ​ and ​, in some embodiments of the present invention, the flow path integration module 100 further includes a welding ring 23. The welding ring 23 is integrally connected to the interface 212 disposed corresponding to the side facing away from the substrate 10, and protrudes from the side surface of the corresponding flow path member 21 facing away from the substrate 10 in the direction away from the substrate 10. The welding ring 23 is connected to the refrigerant circuit through a transition pipe 230, and the transition pipe 230 is inserted 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] Exemplarily, at least one of the interfaces 212 of the flow path module 20 is located on the side of the flow path module 20 facing away from the substrate 10. The interface 212 located on the side of the flow path module 20 facing away from the substrate 10 can be connected to the refrigerant circuit through a transition pipe 230. The transition pipe 230 can be inserted and mated with the welding ring 23 at the corresponding interface 212, so as to facilitate the positioning and assembly of the transition pipe 230 and the flow path module 20, and when the transition pipe 230 is inserted and mated with the welding ring 23, the transition pipe 230 and the welding ring 23 can be...

[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 consumption of the welding ring 23 and reduce the production cost of the flow path integration module 100.

[0215] Among them, when the wall thickness of the welding ring 23 is less than 1 mm, the processing accuracy requirements for the welding ring 23 are high, resulting in great processing difficulty of the welding ring 23; when the wall thickness of the welding ring 23 is greater than 3 mm, it will lead to more material consumption of the welding ring 23, thus resulting in high material cost of the flow path integration module 100, and further resulting in high production cost of the flow path module 20.

[0216] Combined with ​ and ​ , in some embodiments of the present invention, at least one flow path member 21 is connected to the reversing valve 202. The refrigerant circuit further includes a gas-liquid separator 240. The gas-liquid separator 240 includes a separation main body 241, an inlet pipe 242, and a gas outlet pipe 243. The separation main body 241 has a separation chamber and is disposed 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 main body 241 adjacent to the substrate 10. The inlet pipe 242 is arranged to avoid all the interfaces 212, so that the inlet pipe 242 bypasses the flow path integration module 100 and is connected to the reversing valve 202. The inlet pipe 242 and the flow path member 21 are respectively connected to different valve ports of the reversing valve 202.

[0217] Exemplarily, the reversing valve 202 may be located on a side of the flow path module 20 facing away from the substrate 10. The separation body 241 may be disposed on a side of the substrate 10 facing 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 a side of the separation body 241 close to the substrate 10 and connected to the separation body 241, so as to facilitate connecting the separation body 241 to the reversing valve 202 through the inlet pipe 242. The refrigerant passing through the reversing valve 202 may flow into the separation chamber of the separation body 241 through the inlet pipe 242 and achieve separation of gaseous refrigerant and liquid refrigerant in the separation chamber. The separated gaseous refrigerant may flow out of the separation chamber through the gas outlet pipe 243.

[0218] Among them, the inlet pipe 242 is arranged to avoid all the interfaces 212, so that the inlet pipe 242 bypasses the flow path integration module 100 and is connected to the reversing valve 202. For example, the inlet pipe 242 may penetrate through the substrate 10, and in the projection plane in the thickness direction of the substrate 10, the front projection plane of the position where the inlet pipe 242 penetrates through the substrate 10 is misaligned with the front projection planes of all the interfaces 212, so that the inlet pipe 242 bypasses the flow path integration module 100 and is connected to the reversing valve 202. Without respectively connecting the inlet pipe 242 and the reversing valve 202 to the integration module, the integrated setting of the flow path integration module 100, the reversing valve 202 and the gas-liquid separator 240 can be realized, and the connection between the integration module, the reversing valve 202 and the gas-liquid separator 240 can be effectively simplified, the production and processing cost of the air-conditioning system 1000 can be reduced, and the production and processing efficiency of the air-conditioning system 1000 is facilitated to be improved.

[0219] Referring to ​ , in some examples, the flow channel member 21 may include a sixth flow channel member 6. The reversing valve 202 may be only connected to the sixth flow channel member 6 of the flow path module 20. At the same time, the reversing valve 202 may be connected to the inlet pipe 242 of the gas-liquid separator 240. Through the sixth flow channel member 6 and the gas-liquid separator 240, the connection positions of the two valve ports of the reversing valve 202 can be determined, so that the positioning installation of the reversing valve 202 can be realized, and the structure of the flow path module 20 can be effectively simplified, and the production cost of the flow path module 20 can be reduced; combined with ​ and ​ , the flow channel member 21 may include a sixth flow channel member 6 and a third flow channel member 3. The reversing valve 202 may be respectively connected to the third flow channel member 3 and the sixth flow channel member 6. 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, which is beneficial to improving the convenience of the positioning installation of the reversing valve 202.

[0220] Combined with ​, in some embodiments of the present invention, the inlet pipe 242 penetrates through the substrate 10 in 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 on the outer peripheral side of the substrate 10.

[0221] Exemplarily, the inlet pipe 242 is provided 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 penetrate through the substrate 10 from the separation body 241 in the thickness direction of the substrate 10, so as to be connected to 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 setting of the reversing valve 202, the flow path integration module 100 and the gas-liquid separator 240, without separately connecting the reversing valve 202 and the gas-liquid separator 240 to the flow path integration module 100 respectively, effectively simplifying the connection between the integration module, the reversing valve 202 and the gas-liquid separator 240, reducing the production and processing cost of the air-conditioning system 1000, and being beneficial to improving the production and processing efficiency of the air-conditioning system 1000.

[0222] The gas outlet pipe 243 is used to be connected to the suction port 2011 of the compressor 201. By arranging the gas outlet pipe 243 at intervals on the outer peripheral side of the substrate 10, while connecting the gas outlet pipe 243 to the compressor 201, it is possible to prevent interference between the gas outlet pipe 243 and the flow path integration module 100, which is beneficial to improving the assembly convenience of the air-conditioning system 1000.

[0223] Combined with ​ , in some embodiments of the present invention, a partial depression is formed at the outer edge of the substrate 10 to form a second avoidance through-hole 16 for avoiding the gas outlet pipe 243.

[0224] Exemplarily, the gas outlet pipe 243 is connected to the suction port 2011 of the compressor 201. The outer edge of the substrate 10 close to the compressor 201 can be recessed away from the substrate 10 to form a second avoidance through-hole 16, so that when the gas outlet pipe 243 is connected to the suction port 2011 of the compressor 201, the substrate 10 can avoid the gas outlet pipe 243 through the second avoidance through-hole 16, preventing interference between the gas outlet pipe 243 and the substrate 10 from 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 a space outside the substrate 10 for arranging the gas outlet pipe 243, which is beneficial to improving the integration degree of the air-conditioning system 1000 and is beneficial to reducing the volume of the air-conditioning system 1000, realizing the miniaturized design of the air-conditioning system 1000.

[0225] Combined with ​ , ​ and ​, in some embodiments of the present invention, 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 replenishing 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 a second throttling element 206.

[0226] Exemplarily, when gas replenishment is required for the compressor 201, the refrigerant passing through the high-pressure valve 204 can flow into the second heat exchange flow path 2102. A 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 the compressor 201 through the gas replenishing port 2013 of the compressor 201 to achieve gas replenishment for the compressor 201.

[0227] Meanwhile, another part of the refrigerant flowing out of the second heat exchange flow path 2102 can flow towards the first throttling element 205. And during this process, the refrigerant flowing towards the first throttling element 205 can pass through the electronic control radiator 209 and dissipate heat from the electronic control module.

[0228] When gas replenishment is not required for the compressor 201, the second throttling element 206 can be closed to cut off the first heat exchange flow path 2101.

[0229] Combined with ​ and ​ , in 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 to say, in the thickness direction of the substrate 10, the economizer 210 can be completely disposed opposite to the substrate 10, so as 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 direction or the second direction, effectively improving the structural compactness of the air-conditioning system 1000, reducing the volume of the air-conditioning system 1000, and realizing the miniaturized design of the air-conditioning system 1000.

[0230] Combined with ​ , in some other examples, the air-conditioning system 1000 further includes a support plate 300. The support plate 300 includes a connected connection portion 310 and a supporting portion 320. The connection portion 310 is clamped between the substrate 10 and the separation main body 241, and the supporting portion 320 supports the side of the economizer 210 facing away from the substrate 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 clamped 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 to improve the connection reliability between the gas-liquid separator 240 and the flow path integration module 100.

[0232] The supporting portion 320 is located on the side away from the substrate 10 in the thickness direction of the substrate 10 with respect to the connecting portion 310, and the supporting portion 320 can support the surface of the economizer 210 on the side facing away from the substrate 10. Since the connecting portion 310 is connected to the substrate 10 and the separation body 241 respectively, by supporting the economizer 210 with the supporting portion 320 connected to the connecting portion 310, 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 further includes a support plate 300. The support plate 300 includes a connected connecting portion 310 and a supporting portion 320. The connecting portion 310 is clamped between the substrate 10 and the separation body 241, and the supporting portion 320 supports the side of the economizer 210 facing away from the substrate 10. Thus, it is beneficial to improve the integration degree of the air-conditioning system 1000, facilitate the miniaturization design of the air-conditioning system 1000, improve the connection reliability between the gas-liquid separator 240 and the flow path integration module 100, and also improve the assembly reliability of the economizer 210.

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

[0250] The following refers to ​ briefly describe two working modes of the air-conditioning system 1000 according to the embodiments of the present invention.

[0251] Heating mode: The first valve port a and the fourth valve port d of the reversing valve 202 are communicated, and the second valve port b and the third valve port c are communicated. The exhaust 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 from the compressor 201 passes through the fourth valve port d and the first valve port a of the reversing valve 202, and then further flows into the indoor heat exchanger through the low-pressure valve 203 and exchanges heat with the indoor environment to increase the temperature of the indoor environment. After heat exchange, the temperature and pressure of the refrigerant decrease and further flow into the second heat exchange flow path 2102 through the high-pressure valve 204. After passing through the second heat exchange flow path 2102, the refrigerant is branched. Part of the refrigerant flows to the electronic control radiator 209 to cool the electronic control device. The refrigerant passing through the electronic control radiator 209 further passes through the first throttling element 205. The first throttling element 205 throttles the refrigerant, and then the refrigerant passes through the outdoor heat exchanger 208 and further passes through the second valve port b and the third valve port c of the reversing valve 202 and flows into the gas-liquid separator 240. The gaseous refrigerant can flow into the suction port 2011 of the compressor 201 through the gas outlet of the gas-liquid separator 240 to facilitate the next heat exchange cycle.

[0252] At the same time, the other part of the refrigerant passing through the second heat exchange flow path 2102 sequentially passes through the third throttling element 207 and the second throttling element 206 and then flows into the first heat exchange flow path 2101. The third throttling element 207 and the second throttling element 206 can throttle the refrigerant in sequence. After the refrigerant enters the first heat exchange flow path 2101, it exchanges heat with the refrigerant in the second heat exchange flow path 2102 to increase the temperature of the refrigerant in the first heat exchange flow path 2101, and then the refrigerant can further flow into the compressor 201 through the gas replenishing port 2013 of the compressor 201 to replenish gas to the compressor 201.

[0253] Refrigeration mode: The fourth valve port d and the second valve port b of the reversing valve 202 are communicated, the first valve port a and the third valve port c are communicated, 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 by 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 the refrigerant enters the outdoor heat exchanger 208, it exchanges heat with the outdoor environment. The temperature and pressure of the refrigerant after heat exchange are reduced. Then the refrigerant flows into the electronic control radiator 209 after passing through the first throttling element 205. In this process, the first throttling element 205 throttles the refrigerant, and the temperature and pressure of the refrigerant are further reduced. After the refrigerant flows into the electronic control radiator 209, it cools the electronic control module. Then the refrigerant flows into the second heat exchange flow 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. The refrigerant after heat exchange 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 realizes gas-liquid separation. 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 for the next heat exchange cycle.
