In the absence of conflict, the features of the following embodiments and implementations may complement or be combined with each other.

[0028] According to a specific embodiment of the three-way reversing device 3 of the present application, referring to Figure 2 , Figure 7 and Figure 8The three-way reversing device 3 includes a block portion 31, a drive assembly 32, a transmission assembly 33 and a core portion 34, and the core portion 34 is assembled in the block portion 31. The transmission assembly 33 includes a rod portion 331, one end of the rod portion 331 is connected to the drive assembly 32, and the other end of the rod portion 331 is connected to the core portion 34, that is, after the assembly is completed, the transmission assembly 33 is partially assembled in the drive assembly 32, and partially assembled in the block portion 31. The drive assembly 32 can drive the rod portion 331 to rotate counterclockwise or clockwise. Since the rod portion 331 is connected to the core portion 34, the rod portion 331 will drive the core portion 34 to rotate counterclockwise or clockwise.

[0029] In this embodiment, the block portion 31 is substantially a hexahedral structure, and the block portion 31 includes a first surface 310, a second surface 320 and a third surface 330. Figure 7 For example, the first surface 310 is the upper side surface, the second surface 320 is the lower side surface, and the third surface 330 is the right side surface. The block portion 31 includes a first groove portion 314 and a second groove portion 317. The block portion 31 has a first channel 311, a second channel 312, a third channel 313, an installation channel 318, and an assembly channel 316. The second channel 312 and the third channel 313 are not connected in the block portion 31, and the first channel 311 can selectively connect to the second channel 312 or the third channel 313. The first channel 311, the second channel 312, the third channel 313, the installation channel 318 and the assembly channel 316 are all formed with openings on the outer surface of the block part 31, the openings of the second channel 312 and the third channel 313 are located on the same side of the block part 31, that is, the third surface 330, the opening of the first channel 311 is located on the other side of the block part 31, that is, the first surface 310, the opening of the assembly channel 316 is located on another side of the block part 31, and the opening of the installation channel 318 is located on another side of the block part 31, wherein the core part 34 is assembled into the block part 31 through the installation channel 318, and the opening of the installation channel 318 is blocked after the core part 34 is placed into the block part 31. Among them, the opening of the first channel 311 is formed on the bottom wall of the first groove part 314, and the opening of the assembly channel 316 is formed on the bottom wall of the second groove part 317. The first groove portion 314 is formed by partially recessing the first surface 310 into the block portion 31 , and the second groove portion 317 is also recessed into the block portion 31 .

[0030] In order to facilitate the assembly of the components connected to the second channel 312 and the components connected to the third channel 313, the block part 31 also includes a fitting surface 315, which can be a part of the third surface 330. The fitting surface 315 matches the shape of the component, and the fitting surface 315 is arranged to fit the outer surface of the component. For example, the fitting surface 315 is a concave arc, and the component is partially accommodated in the space formed by the concave fitting surface 315, thereby increasing the connection area between the block part 31 and the component and improving the stability of the connection. The openings of the second channel 312 and the third channel 313 are both formed on the fitting surface 315, which is convenient for communication.

[0031] Reference Figure 8 The third channel 313 includes a first sub-channel 3131, a second sub-channel 3132 and a third sub-channel 3133. One end of the third sub-channel 3133 can be communicated with the circulation channel 341, and the other end is communicated with the second sub-channel 3132. One end of the second sub-channel 3132 away from the third sub-channel 3133 is communicated with the first sub-channel 3131. One end of the first sub-channel 3131 away from the second sub-channel 3132 forms an opening at the third surface 330 of the block portion 31. In this embodiment, the second channel 312, the third sub-channel 3133 and the first sub-channel 3131 are arranged in parallel. The third sub-channel 3133 and the second channel 312 are respectively located on opposite sides of the core portion 34. The second sub-channel 3132 is partially inclined relative to the first sub-channel 3131 and partially perpendicular to the first sub-channel 3131. It is understandable that by providing a two-stage second sub-channel 3132 , the third sub-channel 3133 can be connected to the first sub-channel 3131 after turning ninety degrees, so that the openings of the second channel 312 and the third channel 313 can be formed on the same side of the block portion 31 .

[0032] In some other embodiments, the second sub-channel 3132 may also be a one-stage structure, and the second sub-channel 3132 is perpendicular to the first sub-channel 3131. In some other embodiments, the second sub-channel 3132 may also be a one-stage structure, and the second sub-channel 3132 is inclined compared to the first sub-channel 3131.

[0033] The rod 331 of the transmission assembly 33 extends into the block portion 31 through the assembly channel 316, thereby connecting with the core portion 34. The portion of the rod 331 exposed outside the assembly channel 316 is connected to the drive assembly 32, and the drive assembly 32 is partially accommodated in the groove cavity of the second groove portion 317, which is conducive to improving the stability of the installation of the drive assembly 32 and the block portion 31. The component connected to the first channel 311 is partially accommodated in the groove cavity of the first groove portion 314, and the component is attached to or connected to the side wall of the first groove portion 314, which is used to improve the stability of the installation.

[0034] In this embodiment, the core part 34 is located in the mounting hole 318, and the core part 34 can rotate in the mounting hole 318. The core part 34 is roughly spherical and has a circulation channel 341, and the first channel 311 is connected to the circulation channel 341. The core part 34 includes a first hole 342 and a second hole 343, the first hole 342 and the second hole 343 are vertically arranged, and the first hole 342 and the second hole 343 are connected, and the hole cavity of the first hole 342 and the hole cavity of the second hole 343 jointly form the circulation channel 341 of the core part 34, that is, the circulation channel 341 is roughly L-shaped. The rod part 331 is vertically arranged with the first hole 342 and the second hole 343. It can be understood that when the rod part 331 drives the core part 34 to rotate, the first hole 342 and the second hole 343 both rotate counterclockwise or clockwise around the rod part 331.

[0035] One of the first hole 342 and the second hole 343 is communicated with the first channel 311, and the other is communicated with the second channel 312 or the third channel 313. In this embodiment, the first channel 311, the second channel 312 and the first sub-channel 3131 are straight-cylindrical channels, and the second channel 312 and the first sub-channel 3131 are arranged in parallel. The axial extension direction of the first channel 311 is defined as the first direction, and the arrangement direction of the second channel 312 and the first sub-channel 3131 is defined as the second direction. The first direction is parallel to or coincides with the second direction, and the second channel 312 and the first sub-channel 3131 are both perpendicular to the first direction. According to the state of the core body 34, when the axial extension direction of the first hole 342 is parallel to or coincident with the first direction, the axial extension direction of the second hole 343 is perpendicular to the first direction, the first hole 342 is connected to the first channel 311, and the second hole 343 is connected to the second channel 312; when the axial extension direction of the second hole 343 is parallel to or coincident with the first direction, the axial extension direction of the first hole 342 is perpendicular to the first direction, the second hole 343 is connected to the first channel 311, and the first hole 342 is connected to the third channel 313.

[0036] The three-way reversing device 3 has a first working state and a second working state. In the first working state, the first channel 311, the second channel 312 and the circulation channel 341 are connected; in the second working state, the first channel 311, the third channel 313 and the circulation channel 341 are connected.

[0037] In this embodiment, the second channel 312 is arranged in parallel with the first sub-channel 3131, and the openings of the second channel 312 and the third channel 313 are located on the same surface of the block 31. Therefore, when the three-way reversing device 3 is assembled with other components, the components connected to the second channel 312 and the components connected to the third channel 313 can be assembled on the same side of the block 31, so that the structure is more compact and occupies less space after assembly. In addition, the first channel 311 is perpendicular to the first sub-channel 3131 and the third channel 313, and the components connected to the first channel 311 can be arranged close to the components connected to the second channel 312, reducing the occupied space in the first direction, further making the structure more compact after assembly, which is conducive to reducing the occupied space.

The first end cover 114 blocks one end of the first header 11, and the second end cover 115 blocks the other end of the first header 11. The first partition 116 and the second partition 117 are both located between the first end cover 114 and the second end cover 115. The first partition 116 and the second partition 117 are plugged into the first header 11.

The third end cover 124 blocks one end of the second header 12, and the fourth end cover 125 blocks the other end of the second header 12. The third partition plate 126 and the fourth partition plate 127 are both located between the third end cover 124 and the fourth end cover 125. The third partition plate 126 and the fourth partition plate 127 are plugged into the second header 12. The third partition plate 126 and the fourth partition plate 127 are arranged at intervals, thereby dividing the inner cavity of the second header 12 into three chambers, wherein the sixth cavity 123 is between the third end cover 124 and the third partition plate 126, the fourth cavity 122 is between the third partition plate 126 and the fourth partition plate 127, and the third cavity 121 is between the fourth partition plate 127 and the fourth end cover 125.

[0042] It should be understood that, in this embodiment, the first manifold 11 is a pipe, and the first cavity 111, the second cavity 112, and the fifth cavity 113 are formed by separating a pipe by the first partition 116 and the second partition 117.

Similarly, the second manifold 12 may also include at least two pipes, and the sixth cavity 123, the fourth cavity 122, and the third cavity 121 may be located in independent pipes.

[0043] Since the structures of the first end cover 114, the second end cover 115, the third end cover 124, the fourth end cover 125, the first partition 116, the second partition 117, the third partition 126 and the fourth partition 127 and the connection relationship between the partitions and the collecting pipe are well known to those skilled in the art, they are not described in detail in this application.

[0044] Reference Figures 4 to 6 The second heat exchange tube 132 and the first heat exchange tube 131 each include a plurality of flat tubes 13, the length of the flat tube 13 is greater than the width, the width of the flat tube 13 is greater than the thickness, the flat tube 13 has a plurality of through holes arranged along the width direction of the flat tube 13, and all the flat tubes 13 are arranged in parallel along the thickness direction of the flat tube 13.

[0045] The connecting tube 14 and the flat tube 13 are arranged in parallel along the thickness direction of the flat tube 13, and the cross-sectional area of ​​the connecting tube 14 is greater than or equal to the cross-sectional area of ​​the flat tube 13. In this embodiment, the shape of the connecting tube 14 is similar to that of the flat tube 13, the length of the connecting tube 14 is substantially the same as that of the flat tube 13, the width of the connecting tube 14 is substantially the same as that of the flat tube 13, but the thickness of the connecting tube 14 is greater than that of the flat tube 13. In some other embodiments, the shape of the connecting tube 14 may not be similar to that of the flat tube 13, for example, the outer contour of the cross section of the connecting tube 14 is square, circular or other shapes.

[0046] Reference Figure 5 The connecting tube 14 includes at least one middle rib 141, which is located in the inner cavity of the connecting tube 14. The inner cavity of the connecting tube 14 includes at least two chambers, and the middle rib 141 is located between two adjacent chambers. The cross-sectional area of ​​the chamber of the connecting tube 14 is greater than the cross-sectional area of ​​the through hole of the flat tube 13.

[0047] Integrating the connecting pipe 14 connected to the third channel 313 into the heat exchange core 1 and combining it with the three-way reversing device 3 can make the structure of the entire heat exchange assembly 100 more compact and occupy less space. Making the appearance of the connecting pipe 14 flat and similar to the appearance of the flat tube 13 can further make the structure of the heat exchange assembly 100 more compact. Since the connecting pipe 14 only serves as a connection, the processing difficulty of the connecting pipe 14 is relatively small and easy to implement.

[0048] In this embodiment, in order to reduce the heat exchange between the first heat exchange tube 131 and the connecting tube 14, the heat exchange component 100 also includes an intermediate plate 15, one end of the intermediate plate 15 is connected to the first collecting tube 11, and the other end is connected to the second collecting tube 12. The intermediate plate 15 is located between the first heat exchange tube 131 and the connecting tube 14, and is spaced a certain distance from both. This can reduce the heat exchange between the first heat exchange tube 131 and the connecting tube 14, and can also increase the strength of the heat exchange component 100.

The one-way valve 26 is spaced apart from the cover 25 and connected to the cover 25. The one-way valve 26 divides the inner cavity of the cylinder 28 into an upper chamber and a lower chamber. The inner cavity between the cover 25 and the one-way valve 26 is the upper chamber, which is connected to the fifth chamber 113. The inner cavity between the cover 25 and the second end 22 is the lower chamber, which is connected to the first channel 311.

[0055] The heat exchange assembly 100 also includes a four-way device 4, which includes a coil assembly 42 and a base 41. The base 41 is fixedly connected to the second header 12, and the coil assembly 42 is fixedly connected to the base 41. A portion of the coil assembly 42 is located inside the base 41. To facilitate the assembly and fixation of the base 41 and the second header 12, the base 41 includes a first side wall 411. The shape of the first side wall 411 matches the shape of the outer wall of the second header 12, and the first side wall 411 fits the outer wall of the second header 12. For example, the first side wall 411 is concave in a direction away from the second header 12, that is, the first side wall 411 is an inwardly concave arc, and the tube wall portion of the second header 12 is accommodated in the space formed by the inward concave first side wall 411, thereby increasing the connection area between the base 41 and the second header 12 and improving the stability of the connection.

[0056] The base 41 is a roughly hexahedral structure. The base 41 has a first hole 412, a second hole 413, a third hole 414, a fourth hole 415 and a connecting hole 416.

The coil assembly 42 controls whether the connecting channel 416 is connected or not connected with the fourth channel 415, and the coil assembly 42 cooperates with the base 41 to control the size of the opening of the connecting channel 416 and the fourth channel 415. It can be understood that the coil assembly 42 and the base 41 constitute an expansion valve, wherein the first channel 412 is an inlet channel and the fourth channel 415 is an outlet channel, and the structural design of the expansion valve is well known to those skilled in the art, and this application will not be repeated here.

[0058] In the present application, the openings of the first channel 412 and the second channel 413 are both located on the first side wall surface 411, and the first side wall surface 411 is in contact with the second collecting pipe 12. Combined with the arrangement of the three-way reversing device 3 and the connecting pipe 14, the refrigerant in the fourth chamber 122 and the refrigerant in the third chamber 121 can both flow out of the heat exchange component 100 through the third channel 414, or flow out of the heat exchange component 100 from the fourth channel 415 after the flow of the refrigerant is adjusted by the coil assembly 42, so that the heat exchange component 100 has a high degree of integration, a compact structure, and occupies a small space.

[0059] The heat exchange assembly 100 further includes a first connector 5 and a second connector 6. The first connector 5 is fixedly connected to the barrel 28 of the liquid storage assembly 2, and is used to connect the liquid storage assembly 2 and other components, so that the inner cavity of the liquid storage assembly 2 is in communication with the inner cavity of the other components; the second connector 6 is fixedly connected to the second header 12, and is used to connect the second header 12 and other components, so that the inner cavity of the second header 12 is in communication with the inner cavity of the other components.

The second connector 6 has a through hole, which connects the outside of the heat exchange assembly 100 and the through hole on the second header 12 corresponding to the sixth cavity 123.

[0060] According to the second embodiment of the heat exchange assembly 100 of the present application, the structure of this embodiment is substantially the same as that of the first embodiment of the heat exchange assembly 100, except that: Fig.11 and Fig.12 , the heat exchange component 100 does not include the four-way device 4, but includes a third connector 7 and a fourth connector 8. The third connector 7 and the fourth connector 8 are both fixedly connected to the second manifold 12, and are respectively used to connect the second manifold 12 and other components. The third connector 7 is provided with a through hole for connecting the fourth chamber 122 and the outside of the heat exchange component 100, and the fourth connector 8 is provided with a through hole for connecting the third chamber 121 and the outside of the heat exchange component 100. According to the application of the heat exchange component 100 in the thermal management system, the outlets of the third connector 7 and the fourth connector 8 can be connected to the same expansion valve through a pipeline, or connected to an expansion valve respectively, so that the heat exchange component 100 is suitable for different thermal management system structures, and the application scenarios are relatively rich. In this embodiment, the structures of the first connector 5, the second connector 6, the third connector 7 and the fourth connector 8 are roughly the same, and the connector structure is well known to those skilled in the art, and this application will not repeat it here.

[0061] According to the third embodiment of the heat exchange assembly 100 of the present application, the structure of this embodiment is substantially the same as that of the first embodiment of the heat exchange assembly 100, except that: Figures 13 to 15The structure of the first connecting member 5 is different. In this embodiment, the first connecting member 5 is integrated with a valve core of a one-way device, and the first connecting member 5 has a one-way conduction function. Specifically, the first connecting member 5 includes a main body 51, a valve core 52 and a plug cover 53. The main body 51 is fixedly connected to the cylinder 28 of the liquid storage assembly 2.

[0062] The valve core 52 is located in the main body 51, and the valve core 52 is located in the through hole of the first connector 5. The valve core 52 controls the one-way flow of the refrigerant from the outside of the heat exchange assembly 100 to the inside of the cylinder 28, and the reverse flow is cut off. In order to facilitate the assembly of the first connector 5, the liquid storage assembly 2 and other components, and to improve the integration of the heat exchange assembly 100, the through hole of the first connector 5 is roughly in a "Z" shape, and the liquid storage assembly 2 and other components are respectively assembled on the left and right sides of the first connector 5, and the available space is relatively large, and the assembly is more convenient.

[0063] To facilitate the installation of the valve core part 52, the first connecting member 5 is provided with a process hole (not shown in the figure) with one end closed and the other end open, and the plugging cover 53 blocks the open end of the process hole. The plugging cover 53 is at least partially located in the main body 51, and the plugging cover 53 is sealed and connected to the main body 51, and the plugging cover 53 supports and fixes the valve core part 52. The plugging cover 53 can be used to limit the axial displacement of the valve core part 52 while achieving the sealing of the process hole.

[0064] In this embodiment, when the three-way reversing device 3 is in the first working state, the first connecting member 5 is in the cut-off state, the one-way valve 26 of the liquid storage assembly 2 is in the conducting state, the upper chamber of the liquid storage assembly 2 is connected to the lower chamber, the fifth chamber 113 is connected to the upper chamber, and the lower chamber of the liquid storage assembly 2 is connected to the second chamber 112 through the three-way reversing device 3. At this time, the outside of the heat exchange assembly 100 cannot be connected to the lower chamber of the liquid storage assembly 2 through the first connecting member 5; when the three-way reversing device 3 is in the second working state, the first connecting member 5 is in the conducting state, the one-way valve 26 of the liquid storage assembly 2 is in the cut-off state, the upper chamber of the liquid storage assembly 2 is not connected to the lower chamber, the lower chamber of the liquid storage assembly 2 is connected to the first chamber 111 through the three-way reversing device 3, and the outside of the heat exchange assembly 100 is connected to the lower chamber of the liquid storage assembly 2 through the first connecting member 5.

[0065] In some thermal management systems, a liquid storage device is connected in series in the circulation loop of the heating mode, and a liquid storage device is also connected in series in the circulation loop of the cooling mode, which are used to remove moisture and impurities in the refrigerant, ensure the quality of the refrigerant, and improve the quality of the refrigerant cycle. However, the heating mode and the cooling mode will not run at the same time. Therefore, when designing the system, the refrigerant in the cooling mode flow path and the refrigerant in the heating mode flow path can flow through the same liquid storage device respectively, thereby saving the number of components in the system and simplifying the system structure. However, when the heating mode and the cooling mode use the same liquid storage device, refrigerant reflux may occur. If reflux occurs, part of the refrigerant will be stored in components that do not participate in heat exchange, which will reduce the refrigerant flowing in the system, which is not conducive to the operation of the system. The relevant technology requires the use of at least two one-way devices to avoid the occurrence of refrigeration reflux. The heat exchange component 100 in the present application includes a liquid storage component 2 integrated with a one-way valve 26 and a filter-drying device 27, and a first connector 5 integrated with a valve core of a one-way device and connected to the inner cavity of the liquid storage component 2, which can be used to reduce the possibility of refrigerant reflux. The one-way valve 26 is arranged in the cylinder 28, and the core portion 52 is arranged in the first connector 5. In addition, the first connector 5 can also be used as a connecting pressure plate for connecting the heat exchange component 100 with pipelines or components, which is beneficial to saving system pipeline components, and can make the system structure more compact and conducive to miniaturization.

[0066] According to the fourth embodiment of the heat exchange assembly 100 of the present application, the structure of this embodiment is substantially the same as that of the first embodiment of the heat exchange assembly 100, except that: Fig.16 The heat exchange component 100 does not include the four-way device 4, but includes a third connector 7 and a fourth connector 8. The third connector 7 and the fourth connector 8 are both fixedly connected to the second header 12, and are respectively used to connect the second header 12 and other components. The third connector 7 is provided with a through hole for connecting the fourth cavity 122 and the outside of the heat exchange component 100. The fourth connector 8 is provided with a through hole for connecting the third cavity 121 and the outside of the heat exchange component 100. The structure of the first connector 5 is the same as the structure of the first connector 5 in the third embodiment of the heat exchange component 100.

[0067] The "outside of the heat exchange component 100" and "other components" are mentioned many times in this application. It should be understood that when the heat exchange component 100 is applied to a thermal management system, it will be connected to many components, that is, there are many external spaces connected to the heat exchange component 100. The "outside of the heat exchange component 100" mentioned in many places in this application can refer to the same place or different places; the "other components" mentioned in many places in this application can refer to the same place or different places; the "outside of the heat exchange component 100" and "other components" mentioned in many places in this application can also refer to the same place, depending on the specific application of the heat exchange component 100 in the thermal management system.

[0068] The present application also provides a thermal management system, referring to Fig.17 , taking the structure of the heat exchange component 100 as the structure of the third embodiment as an example. In this embodiment, the thermal management system includes a heat exchange component 100, a compressor 200, a three-way valve component 300, an indoor condenser 400, a first flow regulating device 500, an indoor evaporator 600 and an outdoor evaporator 700.

[0069] In this embodiment, the heat exchange assembly 100 is integrated by an outdoor condenser 101, a liquid storage tank 102, a three-way reversing device 3, a subcooling condenser 103, a connecting vessel 104, a first one-way element 105, a second one-way element 106 and a four-way device 4. The function of the outdoor condenser 101 is realized by the fifth cavity 113 of the first header 11, the second heat exchange tube 132 and the sixth cavity 123 of the second header 12; the function of the liquid storage 102 is realized by the lower cavity of the liquid storage assembly 2 and the filter drying device 27; the function of the subcooling condenser 103 is realized by the second cavity 112 of the first header 11, the fourth cavity 122 of the second header 12 and the first heat exchange tube 131; the function of the connecting vessel 104 is realized by the first cavity 111 of the first header 11, the third cavity 121 of the second header 12 and the connecting tube 14; the function of the first one-way element 105 is realized by the one-way valve 26; the function of the second one-way element 106 is realized by the first connecting member 5. The three-way valve assembly 300 controls the refrigerant flowing out of the compressor 100 to flow to the outdoor condenser 101 or to the indoor condenser 400 according to different system working conditions. Optionally, the three-way valve assembly 300 may be a three-way ball valve, or a combination of two stop valves.

[0070] The thermal management system includes a heating mode and a cooling mode, and the heating mode and the cooling mode cannot be executed at the same time.

[0071] In the cooling mode, the three-way valve assembly 300 controls the refrigerant flowing out of the compressor 100 to flow to the outdoor condenser 101, the first flow regulating device 500 is in a throttling state, the four-way device 4 is in a throttling or cut-off state, the second connector 6 connected to the sixth chamber 123 serves as the refrigerant inlet of the heat exchange assembly 100, the four-way device 4 serves as the refrigerant outlet of the heat exchange assembly 100, and the three-way reversing device 3 is in a first working state, that is, the fifth chamber 113 is connected to the second chamber 112 through the three-way reversing device 3. Taking the four-way device 4 in the cut-off state as an example, the compressor 200, the three-way valve assembly 300, the heat exchange assembly 100, the first flow regulating device 500, and the indoor evaporator 600 in the thermal management system are sequentially connected to form a refrigerant circuit.

[0072] Specifically, the high-temperature and high-pressure refrigerant from the compressor 200 enters the heat exchange assembly 100 through the second connector 6, condenses and releases heat in the outdoor condenser 101, and the first one-way element 105 is in a conducting state, and the refrigerant flows into the liquid storage 102 to be filtered and dried. In the liquid storage assembly 2, the one-way valve 26 is in a conducting state at this time, and the refrigerant flows from the upper chamber into the lower chamber through the one-way valve 26, flows through the filter drying device 27 in the lower chamber to be filtered and dried, and then flows out. The refrigerant flowing out of the liquid storage 102 enters the subcooling condenser 103 through the reversing action of the three-way reversing device 3 to further condense and release heat, and then flows out of the heat exchange assembly 100 from the third channel 414 of the four-way device 4, and enters the indoor evaporator 600 after throttling and reducing pressure through the first flow regulating device 500, exchanges heat with the air in the indoor evaporator 600, absorbs the heat of the air to cool it down, and finally returns to the compressor 200, and the cycle continues. In the cooling mode, the heat exchange assembly 100 has the functions of an outdoor condenser 101 and a subcooling condenser 103, and at the same time has the functions of drying, filtering, and storing the refrigerant. After the refrigerant flows into the lower chamber of the liquid storage assembly 2, since the first connector 5 is in a cut-off state, the refrigerant cannot flow out of the heat exchange assembly 100 from the first connector 5, so as to reduce the possibility of the refrigerant backflow phenomenon. When the first connector 5 of the heat exchange assembly 100 does not have a one-way cut-off function, a device with a one-way cut-off function can be connected to the outside of the first connector 5 to achieve the above function.

[0073] In some other embodiments, the refrigerant flowing out of the subcooling condenser 103 can be divided into two paths, one path flows out of the heat exchange component 100 directly from the third channel 414 of the four-way device 4, enters the indoor evaporator 600 after throttling and reducing the pressure through the first flow regulating device 500, and then returns to the compressor 200; the other path flows out of the heat exchange component from the fourth channel 415 of the four-way device 4, and in the four-way device 4, enters the fourth channel 415 after throttling and reducing the pressure through the coil assembly from the connecting channel 416, and then the refrigerant flows out of the heat exchange component 100 from the fourth channel 415 and enters the outdoor evaporator 700, exchanges heat with the air or the coolant circuit 800 in the outdoor evaporator 700, absorbs heat from the air or the coolant circuit 800 to cool it down, and finally returns to the compressor 200.

[0074] In the heating mode, the three-way valve assembly 300 controls the refrigerant flowing out of the compressor 100 to flow to the indoor condenser 400, the first flow regulating device 500 is in the cut-off state, the four-way device 4 is in the throttling state, the first connector 5 serves as the refrigerant inlet of the heat exchange assembly 100, the four-way device 4 serves as the refrigerant outlet of the heat exchange assembly 100, and the three-way reversing device 3 is in the second working state, that is, the first chamber 111 is connected to other components through the three-way reversing device 3. In the thermal management system, the compressor 200, the three-way valve assembly 300, the indoor condenser 400, the heat exchange assembly 100, and the outdoor evaporator 700 are connected in sequence to form a refrigerant circuit.

[0075] Specifically, the high-temperature and high-pressure refrigerant from the compressor 200 flows into the indoor condenser 400 to condense and release heat, heats the air to increase its temperature, and achieves the purpose of heating. Then, it enters the heat exchange assembly 100 through the first connector 5. At this time, the second one-way element 106 is in a conducting state. The refrigerant flows into the liquid storage 102, is filtered and dried, and then passes through the reversing action of the three-way reversing device 3. The refrigerant flows into the connecting vessel 104 from the third channel 313 of the three-way reversing device 3. The refrigerant flowing out of the connecting vessel 104 enters the four-way device 4, and flows out of the heat exchange assembly 100 after throttling and reducing the pressure of the four-way device 4. In the four-way device 4, the refrigerant enters the fourth channel 415 from the connecting channel 416, and throttling and reducing the pressure are achieved in this process. The refrigerant flowing out of the four-way device 4 enters the outdoor evaporator 700, exchanges heat with the air or the coolant circuit 800 in the outdoor evaporator 700, absorbs the heat of the air or the coolant circuit 800 to reduce its temperature, and finally returns to the compressor 200, and the cycle continues. In the heating mode, the outdoor condenser 101 and the subcooling condenser 102 of the heat exchange component 100 do not participate in the heat exchange, and the refrigerant is dried, filtered and stored in the lower chamber of the liquid storage component 2. After the refrigerant flows into the lower chamber, since the one-way valve 26 is in the cut-off state, the refrigerant cannot flow from the one-way valve 26 into the upper chamber and then into the fifth chamber 113, so as to reduce the possibility of refrigerant reflux.

[0076] In some other embodiments, the refrigerant flowing out of the communicating vessel 104 can be divided into two paths. One path flows out of the heat exchange component directly from the third channel 414 of the four-way device 4, enters the indoor evaporator 600 after throttling and reducing the pressure through the first flow regulating device 500, and then returns to the compressor 200. The indoor evaporator 600 is arranged on the upwind side of the indoor condenser 400. The air first passes through the indoor evaporator 600 to reduce the humidity, and then is blown into the passenger compartment after being heated by the indoor condenser 400, so as to achieve the purpose of heating and dehumidification; the other path flows out of the heat exchange component 100 from the fourth channel 415 of the four-way device 4, enters the fourth channel 415 after throttling and reducing the pressure through the connecting channel 416 in the four-way device 4, and then flows out of the heat exchange component 100 from the fourth channel 415 and enters the outdoor evaporator 700, and then returns to the compressor 200. At the outdoor evaporator 700, heat exchange can be carried out with the coolant circuit 800 to achieve cooling of the battery assembly or the motor assembly.

[0077] The present application integrates the outdoor condenser 101, the liquid storage 102, the subcooling condenser 103, the connecting vessel 104, the first one-way element 105, the second one-way element 106, the three-way reversing device 3 and the four-way device 4 to form a heat exchange component 100, and integrates the liquid storage 102 and the first one-way element 105 to form a liquid storage component 2, and the second one-way element 106 is integrated into the first connecting piece 5. The refrigerant can be filtered, dried and stored in the liquid storage component 2 during cooling and heating. During cooling and heating, the refrigerant in the lower chamber is filtered, dried and stored due to the first one-way element. 105 and the second one-way element 106 are both one-way flows, reducing the possibility of backflow, and canceling the pipeline connections between the outdoor condenser 101 and the first one-way element 105, the first one-way element 105 and the liquid reservoir 102, the second one-way element 106 and the liquid reservoir 102, the liquid reservoir 102 and the three-way reversing device 3, and the three-way reversing device 3 and the subcooling condenser 103. A connecting vessel 104 and a four-way device 4 are also provided to reduce the space occupied by the heat exchange component and simplify the system structure, making the system more compact and conducive to the miniaturization of the system.
