Detailed Implementation

[0042] 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.

[0043] Combination Figures 1 to 10 According to an embodiment of the present invention, a thermal management device 100 includes a compression assembly 10 and a heat exchange liquid storage assembly 20. The compression assembly 10 has a first end 101 and a second end 102 opposite to each other along a first direction. The end face of the first end 101 of the compression assembly 10 is provided with an intake port 11 and an exhaust port 12. The heat exchange liquid storage assembly 20 has a first inlet communicating with the exhaust port 12 and a first outlet communicating with the intake port 11. After being compressed by the compression assembly 10, the refrigerant flows into the heat exchange liquid storage assembly 20 through the first inlet and undergoes heat exchange. After heat exchange, the refrigerant flows out of the heat exchange liquid storage assembly 20 through the first outlet, re-enters the interior of the compression assembly 10, and is compressed again by the compression assembly 10. The compressed refrigerant then re-enters a new cycle of cooling and heating.

[0044] The heat exchange storage assembly 20 includes a high-pressure heat exchanger component 21 and a low-pressure heat exchanger component 22. The high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22 are arranged side by side along a second direction at the first end 101 of the compression assembly 10, and the second direction is perpendicular to the first direction. Compared with arranging the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22 along the first direction, arranging the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22 side by side along the second direction can reduce the size of the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22, reduce the length of the thermal management device 100 along the first direction, thereby reducing the overall size of the thermal management device 100, making the components of the thermal management device 100 more compact, reducing the space occupied by the thermal management device 100, which is beneficial to reducing the flow resistance of the refrigerant in the thermal management device 100, and at the same time reducing the production cost of the thermal management device 100.

[0045] According to the embodiment of the present invention, the thermal management device 100 has a high-pressure heat exchanger component 21 and a low-pressure heat exchanger component 22 arranged side by side, which reduces the overall size of the thermal management device 100, which is beneficial to the lightweighting of the thermal management device 100 and improves the integration of the thermal management device 100.

[0046] Combination Figure 2 For example, the first inlet can be located in the high-pressure heat exchanger component 21, and the first outlet can be located in the low-pressure heat exchanger component 22. The compression assembly 10 may include a compressor. The refrigerant compressed by the compressor can be discharged from the exhaust port 12 and enter the high-pressure heat exchanger component 21 through the first inlet for heat exchange. Since the high-pressure heat exchanger component 21 is connected to the low-pressure heat exchanger component 22, the refrigerant after heat exchange flows out of the high-pressure heat exchanger component 21 and into the low-pressure heat exchanger component 22. The compressor can draw air from the suction port 11, and the refrigerant in the low-pressure heat exchanger component flows out from the first outlet and into the compressor. The compressed refrigerant is discharged again from the exhaust port 12 into the high-pressure heat exchanger component 21, thereby realizing the cycle of refrigerant cooling and heating.

[0047] Optionally, the aforementioned first direction can be along the front-back direction (e.g., attached). Figure 1 In the front-back direction, the first end 101 and the second end 102 of the compression component 10 can be arranged along the front-back direction; the aforementioned second direction can be along the left-right direction (e.g., attached). Figure 1 In the left-right direction, the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22 can be arranged in the left-right direction to reduce the overall size of the thermal management device 100; at the same time, the high-pressure heat exchanger component 21 is close to the exhaust port 12 and the low-pressure heat exchanger component 22 is close to the intake port 11, which shortens the refrigerant flow path length, reduces the flow resistance of the flow path, and thus improves the working efficiency of the thermal management device 100.

[0048] 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.

[0049] Combination Figure 1 In some embodiments, the high-pressure heat exchanger component 21 and the compression assembly 10 are distributed along a first direction, and the low-pressure heat exchanger component 22 and the compression assembly 10 are also distributed along the first direction. For example, the first direction can be a front-back direction, and the second direction can be a left-right direction. The high-pressure heat exchanger component 21 and the compression assembly 10 can be arranged along the front-back direction, and the low-pressure heat exchanger component 22 and the compression assembly 10 can also be arranged along the front-back direction. Compared to the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22 being distributed with the compression assembly 10 along the left-right direction or the up-down direction, arranging the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22 along the front-back direction of the compression assembly 10 can reduce the width of the thermal management device 100 (e.g., attached). Figure 1 (left and right directions in the middle) and height (e.g., attached) Figure 1 (in the vertical direction), thereby reducing the space occupied by the thermal management device 100.

[0050] Combination Figure 1 In some embodiments, the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22 are arranged side-by-side along a second direction on the end face of the first end 101 of the compression assembly 10. For example, the first direction can be a front-back direction, and the second direction can be a left-right direction. The high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22 can be arranged side-by-side along the left-right direction. Compared to arranging the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22 along a front-back direction, arranging the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22 side-by-side along the left-right direction can reduce the length of the thermal management device 100 along the front-back direction, thereby reducing the overall volume of the thermal management device 100 and improving the integration of the thermal management device 100.

[0051] Optionally, the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22 can also be arranged side by side in the vertical direction, which can also reduce the length of the thermal management device 100 in the front-to-back direction. This utility model mainly describes the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22 arranged side by side in the horizontal direction, but this is not a limitation on the scope of protection of this utility model.

[0052] Combination Figure 1 , Figure 2 and Figure 10 In some embodiments, the first inlet is located in the high-pressure heat exchanger component 21, and the first inlet is connected to the exhaust port 12 along the first direction; the first outlet is located in the low-pressure heat exchanger component 22, and the first outlet is connected to the suction port 11 along the first direction, which further simplifies the flow path of the thermal management device 100 and reduces costs.

[0053] For example, the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22 can be located on the end face of the first end 101 of the compression assembly 10. The first inlet of the high-pressure heat exchanger component 21 is directly connected to the exhaust port 12, and the first outlet of the low-pressure heat exchanger component 22 is directly connected to the suction port 11. The refrigerant compressed by the aforementioned compressor can flow out of the compressor from the exhaust port 12 and flow into the high-pressure heat exchanger component 21 from the first inlet for heat exchange. Since the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22 are connected, the refrigerant after heat exchange flows from the high-pressure heat exchanger component 21 to the low-pressure heat exchanger component 22. Finally, the refrigerant can flow out from the first outlet and flow into the suction port 11 of the compressor, so that the refrigerant is compressed by the compressor and re-enters the high-pressure heat exchanger component 21, thereby realizing the cycle of refrigerant cooling and heating. The direct connection between the first inlet and the exhaust port 12 and the first outlet and the suction port 11 can reduce the number of flow path pipes in the thermal management device 100 and reduce production costs.

[0054] Optionally, the first direction can be the front-to-back direction, the first inlet and the exhaust port 12 can be connected in the front-to-back direction, and the first outlet and the intake port 11 can be connected in the front-to-back direction, which reduces the number of pipes in the thermal management device 100, thereby reducing production costs.

[0055] Combination Figure 1 and Figure 5 In some embodiments, the heat exchange reservoir assembly 20 further includes a reservoir 211, which is fixedly connected to the side of the high-pressure heat exchanger component 21 away from the compression assembly 10, and is connected to the high-pressure heat exchanger component 21. The reservoir 211 is directly assembled with and connected to the high-pressure heat exchanger component 21, simplifying the flow path of the thermal management device 100 and improving the integration of the thermal management device 100.

[0056] For example, after the refrigerant enters the high-pressure heat exchanger component 21 for heat exchange, some of the gaseous refrigerant releases heat and transforms into liquid refrigerant. Since the high-pressure heat exchanger component 21 and the liquid receiver 211 are connected, the refrigerant after heat exchange flows out of the high-pressure heat exchanger component 21 and into the liquid receiver 211, achieving separation of gaseous and liquid refrigerant. This increases the proportion of gaseous refrigerant in the refrigerant circuit and improves the operating efficiency of the compressor. Compared to using pipes to connect the liquid receiver 211 and the high-pressure heat exchanger component 21, the direct connection between the liquid receiver 211 and the high-pressure heat exchanger component 21 reduces the number of pipes between them, lowers the risk of refrigerant leakage, and thus improves the safety of the thermal management device 100.

[0057] Alternatively, the receiver 211 may be equipped with a desiccant to absorb water vapor and impurities carried in the refrigerant, thereby preventing water vapor from increasing the flow resistance of the refrigerant, reducing the impact of water vapor on the liquefaction and evaporation of the refrigerant, improving the cooling and heating effect of the refrigerant, and thus optimizing the operating performance of the thermal management device 100.

[0058] Optionally, the liquid reservoir 211 may have a liquid inlet and a liquid outlet inside. The liquid outlet may also have a bend to reduce the lateral area of ​​the liquid inlet and the liquid outlet, thereby avoiding hydraulic shock caused by a large outflow of liquid refrigerant.

[0059] Optionally, the high-pressure heat exchanger component 21 and the liquid receiver 211 are integrated into a single unit by welding or bolting. Integrating the high-pressure heat exchanger component 21 and the liquid receiver 211 into a single unit achieves assembly of the thermal management device 100 and connectivity of its internal flow paths. Compared to using connecting pipes to connect individual components, this reduces the number of connecting pipes, increases the integration of the thermal management device 100, and consequently reduces the total volume of the flow paths within the thermal management device 100, lowering the risk of refrigerant leakage. Simultaneously, it significantly reduces the amount of refrigerant required and increases the structural strength of the device, improving the safety of the thermal management system. Furthermore, it saves assembly time for the thermal management system and meets the requirements of tiered assembly on the main assembly line. The reduction in refrigerant charge enhances the safety of the flammable and explosive thermal management system, thereby improving the overall vehicle safety level.

[0060] Combination Figure 1 , Figure 2 and Figure 5In some embodiments, the high-pressure heat exchanger component 21 includes a condenser 212, which is connected to the first inlet and the low-pressure heat exchanger component 22. For example, after the refrigerant is compressed by the aforementioned compressor, it flows out from the exhaust port 12. Since the exhaust port 12 is connected to the first inlet, the compressed refrigerant flows out from the exhaust port 12 and into the condenser 212 from the first inlet. The high-temperature and high-pressure gaseous refrigerant is liquefied and releases heat in the condenser 212, transforming into liquid refrigerant or two-phase refrigerant. Since the condenser 212 is connected to the low-pressure heat exchanger component 22, the refrigerant after heat exchange flows out of the condenser 212 and flows to the low-pressure heat exchanger component 22, completing the condensation process in the cooling and heating cycle of the thermal management device 100.

[0061] Combination Figure 2 and Figure 5 In some embodiments, the high-pressure heat exchanger component 21 includes a liquid receiver 211 and a subcooler 213. The liquid receiver 211 is connected to the condenser 212 and the subcooler 213, and the subcooler 213 is connected to the liquid receiver 211 and the low-pressure heat exchanger component 22. The subcooler 213 enables secondary heat exchange between the condensed saturated liquid and the coolant, further increasing the subcooling of the refrigerant and reducing flash gas generated during the throttling process. This, in turn, helps to increase the evaporation rate of the evaporator 221 and improve the heat exchange efficiency.

[0062] Optionally, the subcooler 213 is located between the liquid receiver 211 and the condenser 212. The subcooler 213 has a through-channel connecting the condenser outlet of the condenser 212 and the liquid receiver inlet of the liquid receiver 211. This ensures that the refrigerant flowing out of the condenser 212 can pass through the subcooler 213 without exchanging heat with it. After entering the liquid receiver 211, the two-phase refrigerant undergoes separation of its static and liquid states. Simultaneously, the liquid receiver outlet of the liquid receiver 211 is connected to the subcooling inlet of the subcooler 213, ensuring that the liquid refrigerant flows out from the liquid receiver outlet and into the subcooling inlet of the subcooler 213, undergoes secondary heat exchange within the subcooler 213, and then flows out of the subcooling outlet. After passing through the subcooler 213, the refrigerant flows directly out of the subcooling outlet and towards the low-pressure controller components.

[0063] In some embodiments, the condenser 212 and the subcooler 213 are integrated into a single unit by welding or bolting. By integrating the condenser 212 and the subcooler 213 into a single unit, the assembly of the high-pressure heat exchanger component 21 and the connection of its internal flow paths are achieved, reducing the number of connecting pipes, increasing the integration of the thermal management device 100, thereby reducing the total volume of the flow channels within the thermal management device 100, reducing the risk of refrigerant leakage, and reducing the amount of refrigerant added. This ensures the safety of the flammable and explosive thermal management system, while also increasing the structural strength of the thermal management device 100 and improving the reliability of the thermal management system.

[0064] Optionally, the first direction can be the front-to-back direction, and the condenser 212 and the subcooler 213 can be distributed along the front-to-back direction to make the flow path between the condenser 212 and the subcooler 213 as short as possible, simplify the number of connecting pipes between the condenser 212 and the subcooler 213, thereby avoiding excessive loss of pressure and heat due to excessively long flow paths and improving the smooth flow of refrigerant.

[0065] Combination Figure 1 , Figure 3 and Figure 4 In some embodiments, the heat exchanger reservoir assembly 20 includes a first valve seat 23. One end of the first valve seat 23 is connected to the low-pressure heat exchanger component 22, and the other end of the first valve seat 23 is connected to the high-pressure heat exchanger component 21. The first valve seat 23 serves as a connection channel between the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22. After heat exchange in the high-pressure heat exchanger component 21, the refrigerant flows into the interior of the first valve seat 23 from the other end of the first valve seat 23 and flows out from one end of the first valve seat 23 into the low-pressure heat exchanger component 22, thereby achieving communication between the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22. This ensures that the refrigerant can circulate normally between the heat exchanger reservoir assemblies 20 and reduces external piping, thereby improving the integration level of the heat exchanger reservoir assembly 20.

[0066] Optionally, the first valve seat 23 can be fixedly connected to the lower end of the low-pressure heat exchanger component 22. The refrigerant outlet of the high-pressure heat exchanger component 21 is located at the lower end of the high-pressure heat exchanger component 21. The first valve seat 23 located at the lower end of the low-pressure heat exchanger component 22 can shorten the flow path of the refrigerant and reduce the flow resistance of the refrigerant, so that the refrigerant can flow smoothly from the high-pressure heat exchanger component 21 into the low-pressure heat exchanger component 22.

[0067] Combination Figure 6 Optionally, the first valve seat 23 and the low-pressure heat exchanger component 22 can be integrated into one unit, which helps to improve the integration of the first valve seat 23 and the low-pressure heat exchanger component 22, reduce external piping, thereby improving the integration of the heat exchange liquid storage assembly 20 and reducing the space occupied by the heat exchange liquid storage assembly 20.

[0068] Combination Figure 1 and Figure 2 In some embodiments, the heat exchange reservoir assembly 20 includes a first valve 24, a first valve seat 23 having a first mounting hole, and the first valve 24 being mounted in the first mounting hole. The first valve 24 acts as a throttling device to regulate the flow rate of refrigerant from the high-pressure heat exchanger component 21 to the low-pressure heat exchanger component 22.

[0069] Specifically, since the first end 101 of the first valve seat 23 is connected to the high-pressure heat exchanger component 21 and the other end of the first valve seat 23 is connected to the low-pressure heat exchanger component 22, and the first valve 24 is installed on the first valve seat 23, the first valve 24 is connected in series between the high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22. The first valve 24 is set at the inlet of the low-pressure heat exchanger component 22. On the one hand, it controls the flow rate of refrigerant into the low-pressure heat exchanger component 22, ensuring that the refrigerant flowing out of the outlet of the low-pressure heat exchanger component 22 is gaseous, reducing the liquid refrigerant content, thereby reducing the possibility of refrigerant entering the compressor and causing liquid slugging, and avoiding insufficient cooling due to insufficient refrigerant flow, ensuring the cooling capacity of the low-pressure heat exchanger component 22 and improving the heat exchange efficiency. On the other hand, it can throttle the low-temperature and low-pressure liquid refrigerant through the throttling orifice of the first valve 24 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.

[0070] Optionally, the first valve 24 can be a throttle valve, an electronic expansion valve, a proportional valve, etc.; the first valve 24 can be integrated into the low-pressure heat exchanger component 22 or the high-pressure heat exchanger component 21, which can further improve the integration level of the heat exchange liquid storage assembly 20, thereby reducing the space occupied by the heat exchange liquid storage assembly 20.

[0071] Combination Figure 1 and Figure 2 In some embodiments, the low-pressure heat exchanger component 22 includes an evaporator 221, which is connected to the high-pressure heat exchanger component 21 and the first outlet. For example, after the gaseous refrigerant undergoes heat exchange in the high-pressure heat exchanger component 21, it is partially converted into liquid refrigerant. Since the evaporator 221 is connected to the high-pressure heat exchanger component 21, the two-phase refrigerant flows from the high-pressure heat exchanger component 21 into the evaporator 221. The refrigerant absorbs heat and vaporizes in the evaporator 221, thus absorbing heat and converting into gaseous refrigerant. Since the suction port 11 is connected to the first outlet, the refrigerant flows through the evaporator 221 and then out of the first outlet, and flows into the suction chamber of the aforementioned compressor through the suction port 11. The compressor can compress the refrigerant again, and the compressed refrigerant can re-enter the high-pressure heat exchanger component 21 for heat exchange, realizing the cooling and heating cycle of the thermal management device 100. The refrigerant can circulate within the thermal management device 100.

[0072] In some embodiments, the compression assembly 10 has an intake chamber and a compression chamber. The compression chamber is located at the first end 101 of the compression assembly 10, and the intake chamber is located at the second end 102 of the compression assembly 10. For example, the first direction can be a front-to-back direction, and the first end 101 and the second end 102 of the compression assembly 10 can be distributed along the front-to-back direction. The intake chamber is away from the heat exchange reservoir assembly 20, and the compression chamber is located at the rear of the intake chamber and communicates with the high-pressure heat exchanger component 21. The compression chamber communicates with the exhaust port 12, and the intake chamber communicates with the intake port 11. The first inlet is located in the high-pressure heat exchanger component 21, and the first outlet is located in the low-pressure heat exchanger component 22. The high-pressure heat exchanger component 21 and the low-pressure heat exchanger component 22 are located on the end face of the first end 101. The compressed refrigerant flows out from the compression chamber through the exhaust port 12. Since the exhaust port 12 is connected to the first inlet, the refrigerant flows from the first inlet into the high-pressure heat exchanger component 21 for heat exchange. The high-pressure heat exchanger component 21 is connected to the low-pressure heat exchanger component 22. The refrigerant after heat exchange flows from the high-pressure heat exchanger component 21 to the low-pressure heat exchanger component 22. The suction port 11 is connected to the first outlet. The refrigerant flows out of the low-pressure heat exchanger component 22 and into the suction chamber. After entering the suction chamber, the refrigerant is compressed again by the aforementioned compressor. The compressed refrigerant enters the compression chamber and flows back into the high-pressure heat exchanger component 21 from the exhaust port 12 to start a new round of cooling and heating cycle.

[0073] Optionally, the compression chamber may be provided with a lubricating oil separation chamber (not shown in the figure), and the exhaust passage may be connected to the lubricating oil separation chamber and the first inlet. The lubricating oil separation chamber is used to separate refrigerant and lubricating oil. Since the compressor operates at a high speed, lubricating oil is required to improve the stability of the compressor operation. The refrigerant discharged by the compressor inevitably carries lubricating oil. The refrigerant carrying lubricating oil can enter the compression chamber and then pass into the lubricating oil separation chamber, where the lubricating oil and refrigerant will be separated.

[0074] Combination Figures 7 to 9 In some embodiments, the compression assembly 10 further includes a first housing 13, a second housing 14, and a compression component, with the compression component disposed within the first housing 13. The second housing 14 has a suction channel 141, one end of which connects to the suction port 11, and the other end connects to the suction chamber of the compression assembly 10. For example, the compression assembly 10 includes a compressor. The first housing 13 can extend along the axial direction of the compressor, and the second housing 14 can extend parallel to the axial direction of the compressor, reducing the thermal resistance during refrigerant flow and improving the performance of the thermal management device 100. By externalizing the suction channel 141, the volume of the compression assembly 10 is reduced, space utilization is improved, and the internal flow path of the compression assembly 10 is simplified, thereby simplifying the structure of the first housing 13 and facilitating refrigerant flow.

[0075] The first outlet is connected to the air intake 11, and the air intake channel 141 is used to guide the refrigerant located in the heat exchange liquid storage component 20 to the air intake chamber, so that the air intake chamber can draw in air.

[0076] Optionally, the compression assembly 10 may also include a third housing, which may be disposed between the first housing 13 and the second housing 14. The connection strength between the first housing 13 and the second housing 14 may be enhanced by providing the third housing. The third housing may also be a plate extending in a direction parallel to the axis of the aforementioned compressor.

[0077] In some embodiments, the compression assembly 10 further includes a high-pressure housing 15 and an end cap housing 16. The high-pressure housing 15 is disposed on the end face of the first end 101, and the end cap housing 16 is disposed on the end face of the second end 102. A first housing 13 is disposed between the high-pressure housing 15 and the end cap housing 16, and a second housing 14 is disposed between the high-pressure housing 15 and the end cap housing 16. This simplifies the structure of the compression assembly 10 and improves its stability and structural strength. At the same time, by using the first housing 13, the second housing 14, the high-pressure housing 15, and the end cap housing 16 to enclose the compression assembly 10, the noise of the thermal management device 100 during operation can be reduced.

[0078] The high-pressure housing 15 is provided with an exhaust channel. One end of the exhaust channel is connected to the exhaust port 12, and the other end of the exhaust channel is connected to the compression chamber of the compression assembly 10. Since the exhaust port 12 is connected to the first inlet, the exhaust channel facilitates the refrigerant in the compression chamber to be guided to the first inlet, so that the refrigerant can flow out of the compression chamber and into the heat exchange storage liquid assembly 20 for heat exchange.

[0079] Optionally, the thermal management device 100 also includes a drive control component, which may be disposed within the end cover housing 16, thereby improving the integration of the thermal management device 100.

[0080] Combination Figure 10 Optionally, the high-pressure housing 15 can be fixed to the first housing 13, the second housing 14 and the third housing by means of bolts or other fixing methods. Multiple bolts can be used to achieve uniform circumferential connection between the high-pressure housing 15 and the first housing 13, the second housing 14 and the third housing, thereby improving the sealing between the housings and ensuring a stable connection between the housings.

[0081] Combination Figure 1 Optionally, a second valve 25 and a third valve 26 may be provided on the high-pressure housing 15. The second valve 25 is used to control the refrigerant to selectively flow to the first inlet and the inlet of the third valve 26. The first end 101 of the second valve 25 can be connected to the compression chamber, the second end 102 of the second valve 25 can be connected to the first inlet, the third port of the second valve 25 can be connected to the inlet of the third valve 26, and the outlet of the third valve 26 can be connected to the suction channel 141.

[0082] The second valve 25 and the third valve 26 can have two working modes. In the first working mode, the second end 102 of the second valve 25 is connected to the first inlet. The refrigerant in the compression chamber can be adjusted by the second valve 25 and flow into the heat exchange liquid storage assembly 20 from the first inlet for heat exchange. At this time, the third valve 26 is in the closed state. In the second working mode, the ordinary refrigerant circulation in the thermal management device 100 cannot meet the cooling and heating requirements of the system. The third valve 26 is in the partially open state. A portion of the refrigerant sent out from the compression chamber can pass through the second valve 25 and enter the heat exchange liquid storage assembly 20. Another portion of the refrigerant passes through the second valve 25 and the third valve 26 and also enters the suction chamber to complete the heating cycle.

[0083] Optionally, the second valve 25 and the third valve 26 can be throttle valves, electronic expansion valves, proportional valves, etc.

[0084] Combination Figure 1 , Figures 7 to 10 In some embodiments, the compression assembly 10 has a first mounting part 31 on the upper part of the first end 101 and a second mounting part 32 on the upper part of the second end 102. The compression assembly 10 has a third mounting part 33 on the lower part of the first end 101 and a fourth mounting part 34 on the lower part of the second end 102. In the projection along the vertical direction, the center of mass of the thermal management device 100 is located in the area enclosed by the first mounting part 31, the second mounting part 32, the third mounting part 33 and the fourth mounting part 34 in the first direction, which ensures that the thermal management device 100 can be in a statically balanced state when upright and hoisted, and avoids the thermal management device 100 from tilting.

[0085] For example, the first mounting part 31 and the second mounting part 32 can be cylindrical, and both extend in the left-right direction. The first mounting part 31 has a first mounting groove, and the second mounting part 32 has a second mounting groove. When the thermal management device 100 is hoisted, the fastener can be fixed by passing through the first and second mounting grooves. The third mounting part 33 can be a mounting bracket, and the third mounting part 33 can have a third mounting hole. The fourth mounting part 34 can have a fourth mounting hole. When the thermal management device 100 is upright, the fastener can be fixed by passing through the third and fourth mounting holes.

[0086] The first mounting part 31 has a first fixing point, the second mounting part 32 has a second fixing point, the third mounting part 33 has a third fixing point, and the fourth mounting part 34 has a fourth fixing point. The center of mass of the thermal management device 100 is located within the horizontal projection area of ​​the plane enclosed by the lines connecting the first, second, third, and fourth fixing points. That is, the center of mass of the thermal management device 100 is located within the area enclosed by the projections of the first mounting part 31, second mounting part 32, third mounting part 33, and fourth mounting part 34 on the horizontal plane. The center of mass being located between the fixing parts can reduce the swaying and shaking of the device under the action of external forces, thereby ensuring that the thermal management device 100 is in a balanced state in the upright position and improving the overall stability of the thermal management device 100.

[0087] Optionally, the second direction can be along the left and right direction, and two third mounting parts 33 can be provided. The two third mounting parts 33 can be respectively provided on both sides of the first end 101 of the compression assembly 10 along the left and right direction; two fourth mounting parts 34 can be provided. The two fourth mounting parts 34 can be provided on both sides of the second end 102 of the compression assembly 10 along the left and right direction. Providing two third mounting parts 33 and two fourth mounting parts 34 can enhance the connection strength between the thermal management device 100 and other components in the vehicle, and ensure the stable connection of the thermal management device 100.

[0088] Optionally, a vibration isolation pad and a support base (not shown in the figure) may be provided at the bottom of the third mounting part 33. The vibration isolation pad can reduce the vibration amplitude of the thermal management device 100 during operation, and the support base can increase the force-bearing area of ​​the thermal management device 100 and ensure the stability of the thermal management device 100 when it is upright.

[0089] Combination Figure 3 and Figure 5 In some embodiments, the high-pressure heat exchanger component 21 includes a first heat exchange fluid flow path 214. The side of the high-pressure heat exchanger component 21 away from the compression assembly 10 is provided with a first heat exchange fluid inlet and a first heat exchange fluid outlet. The first heat exchange fluid flow path 214 is connected between the first heat exchange fluid inlet and the first heat exchange fluid outlet. The first heat exchange fluid flow path 214 is used to exchange heat with the refrigerant in the high-pressure heat exchanger component 21.

[0090] For example, the high-pressure heat exchanger component 21 can be configured as a high-pressure plate heat exchanger, that is, by stacking plates, the gaps between adjacent plates form 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 the refrigerant to flow, and the second inter-plate flow channel is configured as a first heat exchange fluid flow path 214 for the heat exchange fluid to flow. The refrigerant and the heat exchange fluid exchange heat through the plates.

[0091] Optionally, the heat exchange fluid in the first heat exchange fluid flow path 214 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.

[0092] Combination Figure 3 and Figure 6 In some embodiments, the low-pressure heat exchanger component 22 includes a second heat exchange fluid flow path 222. The side of the low-pressure heat exchanger component 22 away from the compression assembly 10 is provided with a second heat exchange fluid inlet and a second heat exchange fluid outlet. The second heat exchange fluid flow path 222 is connected between the second heat exchange fluid inlet and the second heat exchange fluid outlet. The second heat exchange fluid flow path 222 is used to exchange heat with the refrigerant in the low-pressure heat exchanger component 22.

[0093] For example, the low-pressure heat exchanger component 22 can be configured as a low-pressure plate heat exchanger, that is, by stacking plates, the gaps between adjacent plates form a third inter-plate flow channel and a fourth inter-plate flow channel that are not interconnected. The third inter-plate flow channel is configured as a flow path for refrigerant to flow, and the fourth inter-plate flow channel is configured as a second heat exchange fluid flow path 222 for heat exchange fluid to flow. The refrigerant and heat exchange fluid exchange heat through the plates.

[0094] Optionally, the heat exchange fluid in the second heat exchange fluid flow path 222 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.

[0095] Optionally, the first heat exchange fluid flow path 214 can be used to control the temperature and humidity inside the passenger compartment, and the second heat exchange fluid flow path 222 can be used to control the temperature of the battery system and the temperature and humidity inside the passenger compartment.

[0096] Optionally, the second end 102 of the compression assembly 10 may be provided with a refrigerant charging port 37, which facilitates the charging of refrigerant into the compression assembly 10 through the refrigerant charging port 37, simplifies the processing technology of the thermal management device 100, improves the stability and cooling and heating capacity of the thermal management device 100, reduces energy consumption, and is energy-saving and environmentally friendly.

Figure 1(in the left and right direction), the first sensor 35 and the second sensor 36 can be respectively set at the second end 102 of the compression assembly 10 in the left and right direction. The first sensor 35 can be used to monitor the exhaust pressure and temperature of the compression assembly 10, and the second sensor 36 can be used to detect the refrigerant temperature and pressure of the intake channel 141, so as to facilitate the control of the thermal management system.

[0098] 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.

[0099] 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.

[0100] The thermal management device 100 of the present invention is described below with reference to the accompanying drawings.

[0101] Combination Figures 1 to 10 The thermal management device 100 according to an embodiment of the present invention includes a compression assembly 10, a heat exchange liquid storage assembly 20, multiple sensors, multiple fixing bolts 151, a first valve 24, a second valve 25, a third valve 26, and a refrigerant filling port 37. The compression assembly 10 is provided with an end cap housing 16, a high-pressure housing 15, a first housing 13, and a second housing 14. The first housing 13 is disposed between the high-pressure housing 15 and the end cap housing 16, and the second housing 14 is disposed between the high-pressure housing 15 and the end cap housing 16. The compression component is located inside the first housing 13, the intake channel 141 is located inside the second housing 14, the drive control group is located inside the end cover housing 16, and the second valve 25 and the third valve 26 are located inside the high-pressure housing 15. The compression component includes a compressor, the intake chamber of which is located at the first end 101, and the compression chamber of which is located at the second end 102. The first sensor 35 and the second sensor 36 are located on the high-pressure housing 15, and the high-pressure housing 15 is fixedly connected to the first housing 13 and the second housing 14 by bolts. The refrigerant charging port 37 is located on the end cover housing 16.

[0102] The heat exchange liquid storage assembly 20 includes an evaporator 221, a condenser 212, a subcooler 213, and a liquid storage tank 211. The condenser 212 and the subcooler 213 are integrated into one unit. The liquid storage tank 211 is fixed to the rear side of the subcooler 213 in the front-rear direction. The evaporator 221, condenser 212, and subcooler 213 are located on the end face of the high-pressure housing 15 away from the compression assembly 10. The liquid storage tank 211 connects the condenser 212 and the subcooler 213. The lower end of the evaporator 221 is provided with a first valve seat 23. The first valve seat 23 is provided with a first valve 24. The first valve 24 connects the subcooler 213 and the evaporator 221. The evaporator 221 is connected to the suction channel 141, and the condenser 212 is connected to the exhaust channel.

[0103] In this arrangement, the evaporator 221, condenser 212, and subcooler 213 are arranged side by side in the left-right direction. Compared with arranging the evaporator 221, condenser 212, and subcooler 213 in the front-back direction, arranging them side by side in the left-right direction can reduce the space occupied by the evaporator 221, condenser 212, and subcooler 213, thereby reducing the length of the thermal management device 100 in the front-back direction, reducing the overall size of the thermal management device 100, and improving the compactness of the thermal management device 100.

[0104] Combination Figure 2 Under normal circumstances, the second valve 25 and the third valve 26 are in the first working mode, with the second valve 25 open and the third valve 26 closed. The second valve 25 connects the exhaust port 12 and the first inlet. The compressed refrigerant flows from the compression chamber through the first inlet into the condenser 212 for heat exchange. After heat exchange, the refrigerant flows to the liquid receiver 211 for separation of gaseous and liquid refrigerant. After flowing out of the liquid receiver 211, the refrigerant flows into the subcooler 213 to further increase the subcooling degree of the refrigerant. After flowing out of the subcooler 213, the refrigerant flows through the first valve 24 to regulate the flow rate and flows into the evaporator 221 for heat exchange. After heat exchange, the refrigerant flows from the first outlet through the suction channel 141 back to the suction chamber of the compressor. The compressor compresses the refrigerant in the suction chamber, and the compressed refrigerant re-enters the compression chamber. The refrigerant in the compression chamber flows back into the condenser 212, realizing the cooling and heating cycle of the thermal management device 100.

[0105] When the normal refrigerant circulation cannot meet the cooling and heating requirements of the system, the second valve 25 and the third valve 26 are in the second working mode. The second valve 25 is open and the third valve 26 is partially open. A portion of the refrigerant flows through the second valve 25 into the condenser 212. The refrigerant entering the condenser 212 flows sequentially through the condenser 212, the liquid receiver 211, the subcooler 213, the first valve 24, and the evaporator 221, and finally is drawn into the compression assembly 10 through the suction channel 141. At the same time, another portion of the refrigerant also enters the suction channel 141 through the second valve 25 and the third valve 26. The two refrigerants are mixed in the suction channel 141. After mixing, the refrigerant is pressurized again through the compression assembly 10 and flows back into the condenser 212 from the first inlet. This increases the total flow rate of the refrigerant through the compressor 10, increases the output power of the compression assembly 10, and improves the cooling and heating capacity of the thermal management device 100.
