Detailed Implementation

[0040] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0041] Combination Figures 1 to 5According to an embodiment of the present invention, the thermal management device 100 includes a compressor assembly 30, a first heat exchanger assembly 10, and a second heat exchanger assembly 20. The compressor assembly 30, the first heat exchanger assembly 10, and the second heat exchanger assembly 20 are distributed along the axis of the compressor assembly 30. The compressor assembly 30 is disposed between the first heat exchanger assembly 10 and the second heat exchanger assembly 20, and the compressor assembly 30, the first heat exchanger assembly 10, and the second heat exchanger assembly 20 are connected to form a refrigerant circulation loop. After being compressed by the compressor assembly 30, the refrigerant flows into the first heat exchanger assembly 10 for heat exchange. After heat exchange, the refrigerant flows out of the first heat exchanger assembly 10 and flows into the second heat exchanger assembly 20 for a second heat exchange. After the second heat exchange, the refrigerant flows back into the compressor assembly 30 and is recompressed by the compressor assembly 30. The compressed refrigerant then re-enters a new cycle of cooling and heating.

[0042] Compared to placing the first heat exchanger assembly 10 and the second heat exchanger assembly 20 on the same side of the compressor assembly 30, placing the first heat exchanger assembly 10 and the second heat exchanger assembly 20 on opposite sides of the compressor assembly 30 simplifies the assembly structure of the thermal management device 100, improves the integration of the thermal management device 100, and facilitates the individual installation and disassembly of the first heat exchanger assembly 10 and the second heat exchanger assembly 20. Since the first heat exchanger assembly 10 and the second heat exchanger assembly 20 have different operating states and operating environments, separating the first heat exchanger assembly 10 and the second heat exchanger assembly 20 can avoid mutual interference between the operating environments of the first heat exchanger assembly 10 and the second heat exchanger assembly 20, thereby improving the operational stability of the thermal management device 100.

[0043] According to the thermal management device 100 of this utility model embodiment, the compressor assembly 30 is disposed between the first heat exchanger assembly 10 and the second heat exchanger assembly 20, which improves the integration level of the thermal management device 100, simplifies the internal flow path structure, and reduces the space occupied by the thermal management device 100.

[0044] In addition, the thermal management device 100 of this utility model can be used in vehicles or other equipment that requires temperature regulation. This utility model is mainly described in the context of vehicles, but this is not a limitation on the scope of protection of this utility model.

[0045] In some embodiments, the compressor assembly 30 has a first end 301 and a second end 302 distributed along an axis. The first end 301 has a high-pressure chamber, and the second end 302 has a low-pressure chamber. A first heat exchanger assembly 10 is connected to the first end 301, and a second heat exchanger assembly 20 is connected to the second end 302. The first heat exchanger assembly 10 and the second heat exchanger assembly 20 are located at different ends of the compressor assembly 30, which can avoid the temperature of the first heat exchanger assembly 10 during operation and the temperature of the second heat exchanger assembly 20 during operation, thereby improving the cooling and heating efficiency of the thermal management device 100. In addition, the first heat exchanger assembly 10 is close to the high-pressure chamber, and the second heat exchanger assembly 20 is close to the low-pressure chamber, which shortens the flow path length of the refrigerant in the high-pressure chamber into the first heat exchanger assembly 10 and the flow path length of the refrigerant in the second heat exchanger assembly 20 into the low-pressure chamber, thereby reducing the amount of refrigerant used.

[0046] Optionally, the compressor assembly 30 may include a high-pressure housing 77 and a low-pressure housing 76, which are connected. The high-pressure chamber may be located in the high-pressure housing 77 and the low-pressure chamber may be located in the low-pressure housing 76. This can prevent the high-pressure chamber and the low-pressure chamber of the compressor assembly 30 from affecting each other and improve the integration of the compressor assembly 30.

[0047] Combination Figure 2 and Figure 4 In some embodiments, the end face of the first end 301 of the compressor assembly 30 is provided with a first interface 31, which is connected to the high pressure chamber. The first heat exchanger assembly 10 is located on the end face of the first end 301 and is connected to the first interface 31, thereby shortening the flow path of the refrigerant in the high pressure chamber into the first heat exchanger assembly 10 and reducing the amount of refrigerant used.

[0048] For example, the high-pressure chamber is located inside the compressor assembly 30, and the first heat exchanger assembly 10 is connected to the end face of the first end 301 facing away from the high-pressure chamber. The first heat exchanger assembly 10 is connected to the high-pressure chamber, and a first flow path 101 is provided in both the high-pressure chamber and the first heat exchanger assembly 10. One end of the first flow path 101 is connected to the high-pressure chamber, and the other end of the first flow path 101 is connected to the first heat exchanger assembly 10. The first interface 31 can serve as the inlet of the first flow path 101. The refrigerant in the high-pressure chamber can flow into the first heat exchanger assembly 10 through the first flow path 101 and exchange heat, shortening the flow path of the refrigerant from the high-pressure chamber to the first heat exchanger assembly 10, reducing the flow resistance of the refrigerant, and enabling the refrigerant to flow smoothly.

[0049] Optionally, the first interface 31 can be located on the end face of the high-pressure housing 77 near the first heat exchanger assembly 10, which can shorten the length of the first flow path 101 and simplify the flow path structure.

[0050] Combination Figure 2 and Figure 4In some embodiments, the thermal management device 100 has a connection channel 104 that connects the first heat exchanger assembly 10 and the second heat exchanger assembly 20. After heat exchange in the first heat exchanger assembly 10, the refrigerant can flow out of the first heat exchanger assembly 10 through the connection channel 104 and flow to the second heat exchanger assembly 20 for the next heat exchange. This allows the refrigerant to flow within the thermal management device 100 and enables the thermal management device 100 to perform both cooling and heating, simplifying the flow path structure of the connection channel 104.

[0051] In some embodiments, the connecting channel 104 is disposed on the compressor assembly 30. The end face of the first end 301 of the compressor assembly 30 is provided with a second interface 32, which connects to the connecting channel 104. The first heat exchanger assembly 10 is disposed on the end face of the first end 301 and connects to the second interface 32. The end face of the second end 302 of the compressor assembly 30 is provided with a third interface 33, which connects to the connecting channel 104. The second heat exchanger assembly 20 is disposed on the end face of the second end 302 and connects to the third interface 33. After heat exchange, the refrigerant in the first heat exchanger assembly 10 can flow into the second heat exchanger assembly 20 through the connecting channel 104, thereby completing the cooling and heating process of the thermal management device 100. Furthermore, compared to providing multiple flow paths between the first heat exchanger assembly 10 and the second heat exchanger assembly 20, providing a single connecting channel 104 simplifies the flow path structure, shortens the flow path length, and reduces the flow resistance within the connecting channel 104, allowing for smooth refrigerant flow.

[0052] In addition, the connecting channel 104 passes through the compressor assembly 30 and does not exchange heat with the refrigerant and components inside the compressor assembly 30. This avoids heat exchange between the refrigerant in the connecting channel 104 and the refrigerant and components inside the compressor assembly 30. Some of the liquid refrigerant in the connecting channel 104 may be converted into gaseous refrigerant, reducing the heat exchange effect of the first heat exchanger assembly 10. Moreover, the gaseous refrigerant flows into the second heat exchanger assembly 20, where it cannot absorb heat and occupies the heat exchange area, resulting in a decrease in the cooling and heating effect of the thermal management device 100.

[0053] Optionally, the second interface 32 may be located on the end face of the high-pressure housing 77 near the first heat exchanger assembly 10; the third interface 33 may be located on the end face of the low-pressure housing 76 near the second heat exchanger assembly 20.

[0054] In some embodiments, the thermal management device 100 further includes a first valve 40 connected in series in the connection channel 104 and disposed between the first heat exchanger assembly 10 and the second heat exchanger assembly 20. The first valve 40 is used to control the flow of refrigerant from the first heat exchanger assembly 10 to the second heat exchanger assembly 20. The first valve 40 is located at the inlet of the second heat exchanger assembly 20. On the one hand, it controls the flow rate of refrigerant into the second heat exchanger assembly 20, ensuring that the refrigerant flowing out of the outlet of the second heat exchanger assembly 20 is gaseous, reducing the liquid refrigerant content, thereby reducing the possibility of liquid slugging caused by refrigerant entering the compressor, and avoiding insufficient cooling due to insufficient refrigerant flow, ensuring the cooling capacity of the second heat exchanger assembly 20 and improving heat exchange efficiency. On the other hand, it can throttle the low-temperature and high-pressure liquid refrigerant through the throttling orifice of the first valve 40 to become a low-temperature and low-pressure mist-like liquid refrigerant, satisfying the evaporation conditions of the liquid refrigerant, thereby improving the evaporation heat absorption efficiency.

[0055] Combination Figure 5 Optionally, the connecting channel 104 may also include a fourth flow path, which is located between the first valve 40 and the second heat exchanger assembly 20. Since the inlet of the first valve 40 is higher than the outlet of the first valve 40, the fourth flow path is needed to connect the first valve 40 and the second heat exchanger assembly 20. The refrigerant can flow through the first valve 40 and then through the fourth flow path into the second heat exchanger assembly 20, so that the first valve 40 can regulate the flow rate of the refrigerant. Optionally, the first valve 40 may be an electronic expansion valve, a proportional valve, or a throttle valve, etc.

[0056] Combination Figure 4 In some embodiments, the thermal management device 100 has a bypass channel 106 that connects the high-pressure chamber and the second heat exchanger assembly 20. When the normal refrigerant circulation cannot meet the system's cooling and heating requirements, a portion of the refrigerant in the high-pressure chamber can be transported to the second heat exchanger assembly 20 through the bypass channel 106 and mixed with the refrigerant in the second heat exchanger assembly 20, thereby increasing the refrigerant flow rate in the thermal management device 100 and improving its cooling and heating power. Compared to setting multiple flow paths between the high-pressure chamber and the second heat exchanger assembly 20, setting a single bypass channel 106 simplifies the flow path structure and shortens the flow path length. When the refrigerant in the second heat exchanger assembly 20 is insufficient, the refrigerant in the high-pressure chamber can be quickly replenished to the second heat exchanger assembly 20, thereby improving the operating efficiency of the thermal management device 100.

[0057] In some embodiments, a bypass channel 106 is provided on the compressor assembly 30. The first end 301 of the compressor assembly 30 has a fourth interface (not shown in the figure) connected to the bypass channel 106, and the high-pressure chamber is connected to the fourth interface. The second end 302 of the compressor assembly 30 has a fifth interface (not shown in the figure) connected to the bypass channel 106. The second heat exchanger assembly 20 is located on the end face of the second end 302 and connected to the fifth interface. When the ambient temperature is lower than the operating temperature range of the compressor assembly 30, the refrigerant in the high-pressure chamber can flow into the second heat exchanger assembly 20 through the bypass channel 106, increasing the refrigerant flow rate in the second heat exchanger assembly 20, thereby enhancing the cooling and heating capabilities of the thermal management device 100.

[0058] Optionally, the fourth interface may be located on the end face of the high-pressure housing 77 near the second heat exchanger assembly 20; the fifth interface may be located on the end face of the low-pressure housing 76 near the second heat exchanger assembly 20.

[0059] In some embodiments, the thermal management device 100 further includes a second valve 50 connected in series with the bypass channel 106 and positioned between the high-pressure chamber and the second heat exchanger assembly 20. The second valve 50 controls whether the refrigerant in the high-pressure chamber flows into the second heat exchanger assembly 20. When the normal refrigerant circulation can meet the system's cooling and heating needs, the second valve 50 is closed, the bypass channel 106 is not open, and the refrigerant in the high-pressure chamber cannot flow into the second heat exchanger assembly 20 through the bypass channel 106. When the normal refrigerant circulation cannot meet the system's cooling and heating needs, the second valve 50 is open, the bypass channel 106 is open, and the refrigerant in the high-pressure chamber can flow into the second heat exchanger assembly 20 through the bypass channel 106 and mix with the refrigerant in the second heat exchanger assembly 20, increasing the refrigerant flow rate within the thermal management device 100, thereby improving the cooling and heating capabilities of the thermal management device 100.

[0060] Combination Figure 4 and Figure 5 Optionally, the bypass channel 106 may also include a fifth flow path, which is located between the second valve 50 and the second heat exchanger assembly 20. Since the inlet of the second valve 50 is lower than the outlet of the second valve 50, the fifth flow path is needed to connect the second valve 50 and the second heat exchanger assembly 20. The refrigerant can flow through the second valve 50 and then into the second heat exchanger assembly 20 through the fifth flow path, so that the second valve 50 can regulate the flow rate of the refrigerant. Optionally, the second valve 50 may be an electronic expansion valve, a proportional valve, or a throttle valve, etc.

[0061] Combination Figures 3 to 5In some embodiments, the thermal management device 100 has a return channel 105 that connects the second heat exchanger assembly 20 and the low-pressure chamber. After heat exchange in the second heat exchanger assembly 20, the refrigerant flows into the low-pressure chamber through the return channel 105 and re-enters the compressor assembly 30. The compressor assembly 30 has a compression component that draws air from the suction chamber and compresses the refrigerant, causing the refrigerant to re-enter a new cycle of cooling and heating.

[0062] In some embodiments, the second end 302 of the compressor assembly 30 is provided with a sixth interface (not shown in the figure), which connects to the return channel 105. The second heat exchanger assembly 20 is disposed on the end face of the second end 302 and connects to the sixth interface. The sixth interface can serve as the inlet of the return channel 105, allowing the refrigerant in the second heat exchanger assembly 20 to flow into the low-pressure chamber through the return channel 105 and enter a new cycle of cooling and heating.

[0063] Optionally, the sixth interface may be located on the end face of the low-pressure housing 76 near the second heat exchanger assembly 20 to shorten the length of the return channel 105.

[0064] In some embodiments, the return channel 105 includes a first channel 1051 and a second channel 1052, which are connected. The first channel 1051 extends along a direction parallel to the axis of the compressor assembly 30, and the second channel 1052 extends vertically. The compressor assembly 30 includes a compression component that draws in gas from the suction chamber and compresses the refrigerant. The second channel 1052 can transport the gaseous refrigerant in the first channel 1051 to a position closer to the compression component, shortening the suction path of the compression component and thereby improving the compression efficiency of the compressor assembly 30.

[0065] Combination Figure 2 and Figure 3 In some embodiments, the first heat exchanger assembly 10 includes a condenser 11 and a subcooler 12, the condenser 11 being connected to the compressor assembly 30, and the subcooler 12 being connected to the condenser 11 and the second heat exchanger assembly 20.

[0066] For example, the condenser 11 is connected to the high-pressure chamber of the compressor assembly 30. The refrigerant in the high-pressure chamber can flow into the condenser 11 for heat exchange. After heat exchange, the refrigerant flows through the liquid receiver assembly 13 and the subcooler 12 in sequence. The subcooler 12 is connected to the second heat exchanger assembly 20. After secondary heat exchange in the subcooler 12, the refrigerant can flow into the second heat exchanger assembly 20 for the next heat exchange, thus realizing the cooling and heating process of the thermal management device 100.

[0067] Optionally, the condenser 11 and the subcooler 12 are integrated into a single unit by welding, thereby connecting the internal flow paths between the condenser 11 and the subcooler 12, reducing the number of connecting pipes, improving the integration of the thermal management device 100, and thus reducing the total volume of the flow path within the thermal management device 100. This reduces the risk of refrigerant leakage and the amount of refrigerant added, thereby ensuring the safety of the flammable and explosive thermal management system. At the same time, it increases the structural strength of the thermal management device 100 and improves the reliability of the thermal management system.

[0068] In some embodiments, the first heat exchanger assembly 10 includes a receiver assembly 13, which is located on the side of the first heat exchanger assembly 20 near or away from the compressor assembly 30. The receiver assembly 13 is connected to the condenser 11 and the subcooler 12 respectively. The receiver assembly 13 can be located between the subcooler 12 and the compressor assembly 30 to improve the structural strength of the thermal management device 100 and prevent refrigerant leakage from the thermal management device 100 due to the receiver assembly 13 detaching. Alternatively, the receiver assembly 13 can be located on the outside of the condenser 11 and the subcooler 12 away from the compressor assembly 30, making it easy to disassemble the receiver assembly 13 during maintenance, thereby recovering the refrigerant inside the receiver assembly 13 and avoiding refrigerant waste.

[0069] The thermal management device 100 of this utility model is mainly described as having a liquid reservoir assembly 13 located on the side of the first heat exchanger assembly 20 near the compressor assembly 30, but this is not a limitation on the scope of protection of this utility model.

[0070] For example, the first heat exchanger assembly 10 is provided with a first flow path 101, a second flow path 102, and a third flow path 103. The first flow path 101 connects the high-pressure chamber and the condenser 11, the second flow path 102 connects the condenser 11 and the liquid receiver assembly 13, and the third flow path 103 connects the liquid receiver assembly 13 and the subcooler 12. The gaseous refrigerant in the high-pressure chamber flows into the condenser 11 through the first flow path 101 for heat exchange, and part of the gaseous refrigerant is converted into liquid refrigerant. The two-phase refrigerant flows out of the condenser 11 through the second flow path 102 and flows into the liquid receiver. The refrigerant undergoes separation of gaseous and liquid refrigerant in the liquid receiver. The liquid refrigerant flows out of the liquid receiver through the third flow path 103 and flows into the subcooler 12. The liquid refrigerant undergoes secondary heat exchange in the subcooler 12, further reducing the enthalpy of the liquid refrigerant. After the reheating process, the refrigerant flows out from the subcooler 12 and into the second heat exchanger assembly 20 through the connecting channel 104, thereby realizing the cooling and heating process of the thermal management device 100.

[0071] Optionally, the liquid receiver assembly 13 can be integrated with the high-pressure housing 77 of the compressor assembly 30 as a whole, reducing the number of components in the thermal management device 100, thereby increasing the integration level of the thermal management device 100 and enhancing the structural strength of the thermal management device 100, thereby improving the safety of the thermal management system operation.

[0072] In some embodiments, the second heat exchanger assembly 20 includes an evaporator 21, which connects the first heat exchanger assembly 10 and the compressor assembly 30. For example, the evaporator 21 is connected to the first heat exchanger assembly 10 via a connecting channel 104 and to the low-pressure chamber within the compressor assembly 30 via a return channel 105. Refrigerant flowing out of the first heat exchanger assembly 10 flows into the evaporator 21 through the connecting channel 104. After heat exchange in the evaporator 21, the refrigerant flows into the low-pressure chamber through the return channel 105, causing the compression component within the compressor assembly 30 to draw in and compress the refrigerant in the low-pressure chamber. The compressed refrigerant then re-enters the high-pressure chamber, initiating a new cooling and heating cycle.

[0073] In some embodiments, the first heat exchanger assembly 10 includes a first heat exchange fluid flow path 14. The first heat exchanger assembly 10 has a first heat exchange fluid inlet and a first heat exchange fluid outlet on the side opposite to the compressor assembly 30. The first heat exchange fluid flow path 14 is connected between the first heat exchange fluid inlet and the first heat exchange fluid outlet. The first heat exchange fluid flow path 14 is used to exchange heat with the refrigerant in the first heat exchanger assembly 10.

[0074] Optionally, due to the compact internal structure design of the thermal management device 100, the heat exchanger in the first heat exchanger assembly 10 can be a plate heat exchanger, that is, using stacked plates, with the gaps between adjacent plates forming a first inter-plate flow channel and a second inter-plate flow channel that are not interconnected. The first inter-plate flow channel is configured as a flow path for refrigerant, and the second inter-plate flow channel is configured as a first heat exchange fluid flow path 14 for heat exchange fluid. The refrigerant and heat exchange fluid exchange heat through the plates. The heat exchange fluid in the first heat exchange fluid flow path 14 can be an aqueous solution, which is readily available and energy-saving and environmentally friendly, thereby reducing the operating cost of the thermal management device 100; it can also be other types of heat exchange fluids such as oil, a mixture of water and ethylene glycol.

[0075] In some embodiments, the second heat exchanger assembly 20 includes a second heat exchange fluid flow path 22. The second heat exchanger assembly 20 has a second heat exchange fluid inlet and a second heat exchange fluid outlet on the side opposite to the compressor assembly 30. The second heat exchange fluid flow path 22 is connected between the second heat exchange fluid inlet and the second heat exchange fluid outlet. The second heat exchange fluid flow path 22 is used to exchange heat with the refrigerant in the second heat exchanger assembly 20.

[0076] Optionally, due to the compact internal structure design of the thermal management device 100, the heat exchanger in the second heat exchanger assembly 20 can be a plate heat exchanger, that is, using stacked plates, with the gaps between adjacent plates forming a third and fourth inter-plate flow channel that are not interconnected. The third inter-plate flow channel is configured as a flow path for refrigerant, and the fourth inter-plate flow channel is configured as a first heat exchange fluid flow path 14 for heat exchange liquid. The refrigerant and heat exchange fluid exchange heat through the plates. The heat exchange fluid in the second heat exchange fluid flow path 22 can be an aqueous solution, which is readily available and energy-saving and environmentally friendly, thereby reducing the operating cost of the thermal management device 100; or it can be other types of heat exchange fluid such as oil, a mixture of water and ethylene glycol.

[0077] Optionally, the first heat exchange fluid flow path 14 can be used to control the temperature and humidity inside the passenger compartment, and the second heat exchange fluid flow path 22 can be used to control the temperature of the battery system and the temperature and humidity inside the passenger compartment. The heat exchange fluid flow paths in other components can be equipped with independent external radiators and control the temperature of the electric drive system, so as to ensure that the various functional systems of the vehicle reach a good operating state, ensure the driving and riding comfort of the driver and passengers, and also ensure the stable and reliable operation of the vehicle.

[0078] In some embodiments, the compressor assembly 30 has a high-voltage connector 60 for connecting to an external controller, which provides high-voltage wiring to the compressor assembly 30. Compared to using a complete control module, providing a separate high-voltage connector 60 simplifies the structure of the thermal management device 100, thereby further reducing the overall size of the thermal management device 100 and improving its integration.

[0079] Combination Figures 1 to 3 In some embodiments, the high-pressure connector 60 is located at the end of the compressor assembly 30 near the second heat exchanger assembly 20. The compressor assembly 30 includes a compression component for compressing refrigerant, and a motor 73 in the compression component is located near the end of the second heat exchanger assembly 20. The high-pressure connector 60 is electrically connected to the motor 73. The location of the high-pressure connector 60 near the motor 73 can shorten the connection length between the motor 73 and the high-pressure connector 60, thereby reducing power loss.

[0080] For example, the compression component includes a motor 73 spindle, a motor 73, a scroll plate 74, a first bearing, a second bearing, a first balance block 71, and a second balance block 72. A high-voltage connector 60 connects to the high-voltage wiring harness of an external controller, providing high-voltage electricity to the compression component and implementing the interlocking function of the high-voltage system. The high-voltage connector 60 connects to the motor stator via a high-voltage cable, providing three-phase AC power with adjustable frequency and voltage, generating a rotating magnetic field through the motor stator coils. The motor rotor rotates under the influence of this rotating magnetic field, revolving around the axis formed by the first and second bearings. A first balance block 71 and a second balance block 72 are installed at the ends of the motor spindle and motor rotor, respectively. These two balance blocks counteract the unbalanced forces generated by the movement of the motor rotor and scroll plate 74, reducing vibration of the compression component. The scroll plate 74 and the motor rotor are connected together via the motor spindle, and the scroll plate 74 undergoes helical translation under the drive of the motor rotor.

[0081] Optionally, the high-pressure connector 60 is positioned on the peripheral wall of the compressor assembly 30 to facilitate fixing of the high-pressure connector 60 and to facilitate connection of an external controller.

[0082] Optionally, at least a portion of the high-pressure connector 60 protrudes from the outer peripheral surface of the compressor assembly 30 to facilitate connection to the wiring harness of an external controller.

[0083] Optionally, at least a portion of the high-voltage connector 60 is embedded in the peripheral wall of the compressor assembly 30 to facilitate electrical connection between the high-voltage connector 60 and the compression component. The high-voltage connector 60 can be connected to the stator in the compression component via a high-voltage cable to provide AC power to the stator.

[0084] Optionally, a bearing bracket 75 may be provided inside the compressor assembly 30, and a sliding bearing may be installed inside the bearing bracket 75 to support the end of the main shaft of the motor 73; multiple brackets 78 may be provided on the low-pressure housing 76 and the high-pressure housing 77, and each bracket 78 may be connected to a vibration isolation pad (not shown in the figure) by bolts. The vibration isolation pad is connected to the thermal management device 100, thereby isolating the vibration generated by the thermal management device 100 during operation and preventing the vibration from being transmitted to the vehicle, thus improving the user experience; the first heat exchanger assembly 10 and the second heat exchanger assembly 20 may be installed on both sides of the compressor assembly 30 by multiple fixing bolts (not shown in the figure), thereby ensuring a stable connection between the first heat exchanger assembly 10 and the compressor assembly 30 and a stable connection between the second heat exchanger assembly 20 and the compressor assembly 30.

[0085] The thermal management system according to the present utility model includes the aforementioned thermal management device 100. The specific structure of the thermal management device 100 is as described in the above embodiments. Since the present thermal management system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0086] The vehicle according to the present utility model includes the aforementioned thermal management device 100, thermal management system and / or the specific structure of the vehicle refers to the above embodiments. Since the vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0087] The thermal management device 100 of the present invention is described below with reference to the accompanying drawings.

[0088] Combination Figures 1 to 5 The thermal management device 100 according to an embodiment of the present invention includes a compressor assembly 30, a first heat exchanger assembly 10, a second heat exchanger assembly 20, a first valve 40, a second valve 50, a first heat exchange fluid flow path 14, a second heat exchange fluid flow path 22, and a high-pressure connector 60. The compressor assembly 30 is disposed between the first heat exchanger assembly 10 and the second heat exchanger assembly 20, and the high-pressure connector 60 is disposed at the upper end of the compressor assembly 30. The first heat exchanger assembly 10 and the compressor assembly 30 are connected along the axial direction, and the second heat exchanger assembly 20 and the compressor assembly 30 are connected along the axial direction, thereby improving the integration level of the thermal management device 100, simplifying the internal flow path structure, and reducing the space occupied by the thermal management device 100.

[0089] The high-pressure connector 60 is located on the top of the low-pressure housing 76 and close to the second heat exchanger assembly 20. The separate high-pressure connector 60 can simplify the structure of the thermal management device 100, thereby further reducing the overall size of the thermal management device 100 and improving the integration of the thermal management device 100.

[0090] Additionally, the first heat exchanger assembly 10 includes a condenser 11, an evaporator 21, and a liquid receiver assembly 13. The condenser 11 and the subcooler 12 are integrated into one unit. The liquid receiver assembly 13 is located between the high-pressure housing 77 and the subcooler 12. The liquid receiver is connected to the condenser 11 and the subcooler 12. The condenser 11 is connected to the high-pressure chamber. The second heat exchanger assembly 20 includes an evaporator 21. The evaporator 21 is connected to the end face of the low-pressure housing 76 away from the compression component. A connecting channel 104 connects the subcooler 12 and the evaporator 21. A bypass channel 106 connects the high-pressure chamber and the evaporator 21. A return channel 105 connects the evaporator 21 and the low-pressure chamber.

[0091] Combination Figure 5In both cooling and heating modes, the compressed refrigerant flows out of the high-pressure chamber and into the condenser 11 through the first flow path 101 to dissipate heat. The cooled refrigerant then flows into the liquid receiver assembly 13 through the second flow path 102 for separation of gaseous and liquid refrigerant. The liquid refrigerant flows into the subcooler 12 through the third flow path 103 for secondary heat exchange, increasing its subcooling degree. After exiting the subcooler 12, the refrigerant flows to the evaporator 21 through the connecting channel 104. A first valve 40 is installed on the connecting channel 104, regulating the refrigerant flow rate and reducing its pressure to a low-temperature, low-pressure liquid refrigerant. After passing through the first valve 40, the refrigerant flows into the evaporator 21 through the fourth flow path. In the evaporator 21, the refrigerant absorbs heat from the aqueous solution in the second heat exchange liquid flow path 22 to achieve the cooling function. After heat exchange, the gaseous refrigerant flows into the low-pressure chamber of the compressor assembly 30 through the return channel 105. The refrigerant in the low-pressure chamber is compressed and then re-enters the high-pressure chamber, starting a new cycle of cooling and heating. Meanwhile, the second valve 50 is closed, the bypass channel 106 is not open, and there is no refrigerant flow.

[0092] When the ambient temperature is below the operating temperature range of the compressor assembly 30, the refrigerant in the evaporator 21 cannot evaporate effectively, limiting the refrigerant flow and heating capacity of the thermal management system. The second valve 50 opens, and the bypass channel 106 is open. The high-temperature, high-pressure refrigerant in the high-pressure chamber enters the inlet of the second valve 50 through the bypass channel 106. After flowing through the second valve 50, the refrigerant flows into the evaporator 21 through the fifth flow path. In the evaporator 21, the high-temperature, high-pressure refrigerant mixes with the low-temperature refrigerant flowing in from the first valve 40. After mixing, it enters the low-pressure chamber of the compressor assembly 30 through the return channel 105. The bypass channel 106 enables hot gas bypass, increasing the refrigerant flow within the device, thereby allowing the thermal management device 100 to output greater heating power and improving its heating capacity.
