Without conflict, the features in the following various embodiments and implementation manners can be combined arbitrarily with each other.

[0027] The vehicle of the present application is adapted to high-temperature regions where the cold demand is strong and the heat demand is not very strong. Such a region can be, for example, the Middle East region. The vehicle includes multiple working modes, which include but are not limited to one or more combinations of an air-conditioning heating mode, a battery heating mode, a battery preheating mode, an air-conditioning cooling mode, a battery cooling mode, a motor cooling mode, and a heat exchanger cooling mode. The vehicle includes a thermal management system for controlling the operation of one or more combinations of the working modes.

[0028] Figure 1 The principle block diagram of the thermal management system 1 of the present application is shown. As Figure 1 shown, the thermal management system 1 includes a compressor 11, a first heat exchanger 12, a second heat exchanger 13, a heat dissipation component 14, a control valve 15, a motor component 16, a third heat exchanger 17, a battery component 18, and a heating core 19. In Figure 1In the illustrated embodiment, the vehicle thermal management system 1 can be adapted to regions with not very strong heat demand, and is used to implement at least one or a combination of multiple working modes including the independent heat dissipation mode of the first heat exchanger 12, the shared heat dissipation mode of the motor assembly 16 and the first heat exchanger 12, the heat dissipation mode of the heat dissipation assembly 14 for the battery assembly 18, the heat pump heating mode for the passenger compartment, and the heating mode of the waste heat of the motor assembly 16 for the battery assembly 18. For details, please refer to the embodiments below. Figures 2 to 6 as shown in the embodiment of

[0029] In Figure 1 the illustrated embodiment, the control valve 15 includes a five-way valve. The control valve 15 includes a first communication port 151, a second communication port 152, a third connection port 153, a fourth communication port 154, and a fifth communication port 155. The control valve 15 is selectively switched between the above five communication ports to achieve the switching between the above working modes. In this embodiment, the control valve 15 includes an electric control valve. The on / off of the communication ports of the electric control valve is controlled by the vehicle on-board controller. In some other embodiments, the control valve 15 can also be other valves, which is not limited.

[0030] Figure 2 Shown is Figure 1 a principle block diagram of an embodiment of the thermal management system 1 as shown. As Figure 2 shown, the compressor 11, the first heat exchanger 12, and the second heat exchanger 13 are connected and form a first heat exchange circuit S1. The first heat exchange medium is filled in the first heat exchange circuit S1. The first heat exchange medium can be a refrigerant, for example, it can be a refrigerant medium. The control valve 15 is selectively controlled so that when the first communication port 151 is communicated with the second communication port 152, the heat dissipation assembly 14 is communicated with the first heat exchanger 12 to form a second heat exchange circuit S2, and the second heat exchange medium is filled in the second heat exchange circuit S2. The second heat exchange medium can be a coolant, for example, it can be cooling water. The first heat exchanger 12 exchanges heat between the first heat exchange medium in the first heat exchange circuit S1 and the second heat exchange medium in the second heat exchange circuit S2, and the heat dissipation assembly 14 dissipates heat from the second heat exchange medium in the second heat exchange circuit S2. In this embodiment, the first heat exchanger 12 can be a water-cooled condenser. The second heat exchanger 13 can be an evaporator. As Figure 2As shown by the arrows, when both the first heat exchanger 12 and the passenger compartment 20 have a cooling requirement, the compressor 11 is controlled to start. The compressor 11 compresses the first heat exchange medium (refrigerant) and then outputs high-temperature and high-pressure gas. After passing through the first heat exchanger 12, the first heat exchanger 12 condenses and dissipates heat, and the output is high-temperature and high-pressure refrigerating liquid. Then it passes through the second heat exchanger 13, the second heat exchanger 13 absorbs heat and cools down, and outputs low-temperature and low-pressure gas. Finally, the low-temperature and low-pressure gas refrigerant returns from the second heat exchanger 13 to the compressor 11, thus realizing the refrigeration function of the passenger compartment. In the above process, the heat of the first heat exchange medium (refrigerant) will be taken away by the second heat exchange medium (cooling water), causing the temperature of the second heat exchange medium (cooling water) to rise. If the second heat exchange medium (cooling water) is not cooled in time, it may affect the temperature of the first heat exchange medium (refrigerant), thereby affecting the refrigeration effect of the passenger compartment 20. Therefore, in this embodiment, the heat dissipation component 14 is used to dissipate heat from the second heat exchange medium (cooling water) in the first heat exchanger 12, so as to realize the independent heat dissipation mode of the first heat exchanger 12, enhance the refrigeration effect of the passenger compartment 20 of the vehicle, be adaptable to areas with strong cooling requirements, reduce system complexity, and reduce the weight and cost of the whole vehicle.

[0031] In Figure 2 the embodiment shown, the compressor 11, the first heat exchanger 12 and the third heat exchanger 17 are connected and form a third heat exchange circuit S3. The third heat exchange circuit S3 is filled with a first heat exchange medium. The first heat exchange medium can be a refrigerant, for example, it can be a refrigerant. The control valve 15 is selectively controlled so that when the fourth communication port 154 and the fifth communication port 155 are connected, the third heat exchanger 17 is connected to the battery assembly 18 and forms a fourth heat exchange circuit S4. The fourth heat exchange circuit S4 is filled with a second heat exchange medium. The second heat exchange medium can be a coolant, for example, it can be cooling water. The third heat exchanger 17 exchanges heat between the first heat exchange medium in the third heat exchange circuit S3 and the second heat exchange medium in the fourth heat exchange circuit S4 to dissipate heat from the battery assembly 18. In this embodiment, the first heat exchanger 12 can be a water-cooled condenser. The third heat exchanger 17 can be a cooler. As Figure 2As shown by the arrow in [Fig. 0], when the battery module 18 has a cooling requirement, the compressor 11 is controlled to operate. The compressor 11 compresses the first heat exchange medium (refrigerant) and outputs high-temperature and high-pressure gas. After passing through the first heat exchanger 12, the first heat exchanger 12 condenses and dissipates heat, and the output is high-temperature and high-pressure refrigerating liquid. Then it passes through the third heat exchanger 17. The third heat exchanger 17 can act as an evaporator, absorb heat and cool down, and output low-temperature and low-pressure gas. Finally, the low-temperature and low-pressure gas refrigerant returns from the third heat exchanger 17 to the compressor 11. The first heat exchange medium (low-temperature and low-pressure refrigerating gas) output by the third heat exchanger 17 exchanges heat with the second heat exchange medium (cooling water). The temperature of the second heat exchange medium (cooling water) decreases, which can cool down the battery module 18, thus realizing the cooling function of the battery module 18. In this working mode, the motor module 16 has no heat exchange requirement, which is suitable for the fast charging mode of the battery module 18, can extend the service life of the battery module 18, and reduce the failure risk of the battery module 18. This thermal management system 1 can, on the basis of realizing the independent heat dissipation mode of the first heat exchanger 12 and the cooling function of the passenger compartment 20, also realize the cooling of the battery module 18, and realize the common heat dissipation of the first heat exchanger 12 and the battery module 18. The system implementation method and structure are simple.

[0032] Figure 3 As shown in Figure 1 the schematic block diagram of another embodiment of the thermal management system 1 shown in [Fig. 0]. Figure 3 The embodiment shown in Figure 1 the embodiment shown in [Fig. 0] is similar. The main difference is that, in Figure 3 the embodiment shown in [Fig. 0], the control valve 15 is selectively controlled so that when the first communication port 151 is in communication with the second communication port 152 and the second communication port 152 is in communication with the third communication port 153, the motor module 16 is in parallel with the second heat exchange circuit S2, and the motor module 16 is in communication with the heat dissipation module 14. The heat dissipation module 14 cools down the second heat exchange medium in the second heat exchange circuit S2 and dissipates heat from the motor module 16. In this embodiment, as Figure 3 shown by the arrow in [Fig. 0], when there are cooling requirements for the vehicle passenger compartment 20, the first heat exchanger 12, the motor module 16, and the battery module 18, the compressor 11, the first heat exchanger 12, the second heat exchanger 13, and the third heat exchanger 17 are controlled to work together, which not only realizes the independent heat dissipation mode of the first heat exchanger 12 and the cooling function of the passenger compartment 20, but also realizes the cooling of the battery module 18 and the motor module 16. In this embodiment, the motor module 16 is in parallel with the second heat exchange circuit S2, and the motor module 16 is in communication with the heat dissipation module 14. By using the same heat dissipation module 14, not only can the first heat exchanger 12 be dissipated of heat, but also the motor module 16 can be cooled. In this way, the branch for adjusting the flow rate of the cooling water can be omitted, the system complexity can be reduced, and the vehicle weight and cost can be reduced.

[0033] Figure 4 As shown inFigure 1 Schematic block diagram of another embodiment of the thermal management system 1 shown. Figure 4 The embodiment shown is similar to Figure 1 the embodiment shown. The main difference is that, in Figure 4 the embodiment shown, the control valve 15 is selectively controlled such that when the first communication port 151 communicates with the fourth communication port 154 and the second communication port 152 communicates with the fifth communication port 155, the second heat exchange circuit S2 and the fourth heat exchange circuit S4 communicate and form a fifth heat exchange circuit S5. The heat dissipation assembly 14 cools the second heat exchange medium in the fifth heat exchange circuit S5 to dissipate heat from the battery assembly 18, wherein the first heat exchanger 12, the second heat exchanger 13, and the third heat exchanger 17 do not work. In this embodiment, as Figure 4 indicated by the arrows in, this mode is applicable to spring and autumn seasons when there is no cooling demand and no heating demand, and the compressor 11, the first heat exchanger 12, the second heat exchanger 13, and the third heat exchanger 17 do not need to work. The heat dissipation assembly 14 and the battery assembly 18 are connected in series, and the heat dissipation assembly 14 is used to cool or maintain the temperature of the battery assembly 18. In this way, at a lower power consumption, the temperature of the battery assembly 18 can be effectively maintained, thereby reducing costs.

[0034] Figure 5 Shown as Figure 1 Schematic block diagram of another embodiment of the thermal management system 1 shown. As Figure 5 shown, the heating core 19 is provided in the passenger compartment 20. When the heating core 19 works, it can heat the passenger compartment 20. The compressor 11, the first heat exchanger 12, and the third heat exchanger 17 all work. The second heat exchanger 13 does not work. The heating core 19 communicates with the first heat exchanger 12 and forms a sixth heat exchange circuit S6. The second heat exchange medium is filled in the sixth heat exchange circuit S6. The second heat exchange medium can be a coolant, such as cooling water. The heating core 19 is used to heat the second heat exchange medium in the sixth heat exchange circuit S6 to heat the first heat exchange medium in the third heat exchange circuit S3. The first heat exchange medium can be a refrigerant, such as refrigerant. The control valve 15 is selectively controlled such that when the second communication port 152 communicates with the fifth communication port 155 and the third communication port 153 communicates with the fourth communication port 154, the fourth heat exchange circuit S4 communicates with the motor assembly 16 and the heat dissipation assembly 14 and forms a seventh heat exchange circuit S7. The second heat exchange medium is filled in the seventh heat exchange circuit S7. The third heat exchanger 17 exchanges heat between the first heat exchange medium in the third heat exchange circuit S3 and the second heat exchange medium in the seventh heat exchange circuit S7, and heats the second heat exchange medium in the seventh heat exchange circuit S7 to heat the battery assembly 18 and the motor assembly 16 respectively. In this embodiment, as Figure 5As shown by the arrow in the figure, when there is a heating requirement for the passenger compartment 20, the motor assembly 16, and the battery assembly 18 of the vehicle, the heating core 19 is controlled to work. On the one hand, the heating function of the passenger compartment 20 can be realized; on the other hand, the second heat exchange medium in the sixth circuit S6 can be heated by the heating core 19 to heat the first heat exchange medium in the third heat exchange circuit S3, so as to indirectly heat the temperature of the second heat exchange medium in the seventh heat exchange circuit, thus realizing the common heating function of the motor assembly 16 and the battery assembly 18. This thermal management system 1 is applicable to the situation where the vehicle has just started and the ambient temperature is around -15°C, and the passenger compartment, the motor assembly 16, and the battery assembly 18 of the vehicle all need to be heated, with lower system complexity and cost.

[0035] Figure 6 As shown Figure 1 is a schematic block diagram of another embodiment of the thermal management system 1 shown. Figure 6 The embodiment shown is similar to Figure 5 the embodiment shown. The main difference is that in Figure 6 the embodiment shown, the compressor 11, the first heat exchanger 12, the second heat exchanger 13, the third heat exchanger 17, and the heating core 19 do not work. The motor assembly 16 and the battery assembly 18 are connected in series to form a seventh heat exchange circuit S7. The motor assembly 16 generates heat and transfers the heat to the second heat exchange medium in the seventh heat exchange circuit S7 to heat the battery assembly 18. Figure 6 The embodiment shown is compared with Figure 5 the embodiment shown. It is applicable to the situation where the ambient temperature is around 0°C and the vehicle has started running. The waste heat of the motor assembly 16 is used to heat the battery assembly 18, and there is no need for the compressor 11, the first heat exchanger 12, the second heat exchanger 13, the third heat exchanger 17, and the heating core 19 to work, reducing the power consumption and cost of the whole vehicle.

[0036] In Figure 5 and Figure 6 the embodiment shown, the thermal management system 1 further includes a switching valve 21, which is connected to the heat dissipation assembly 14. The switching valve 21 includes a first switching port 211, a second switching port 212, and a third switching port 213. In Figure 2 , Figure 3 and Figure 4 the embodiment shown, the switching valve 21 is selectively switched so that when the first switching port 211 is communicated with the second switching port 212, the first heat exchanger 12 is communicated with the heat dissipation assembly 14. In Figure 5 the embodiment shown, the switching valve 21 is selectively switched so that when the first switching port 211 is communicated with the third switching port 213, the first heat exchanger 12 is communicated with the heating core 19. By setting the switching of the switching valve 21, the structure is simple and the cost is low.

[0037] In Figure 1In the illustrated embodiment, the thermal management system 1 further includes an internal heat exchanger 22, which is respectively connected to the compressor 11, the first heat exchanger 12 and the second heat exchanger 13. By providing the internal heat exchanger 22, the on-off of the heat exchange pipeline between the first heat exchanger 12 and the second heat exchanger 13 is controlled to improve the heat exchange efficiency of the system. In Figure 1 In the illustrated embodiment, the thermal management system 1 further includes a communication branch 23, which is connected between the first heat exchange circuit S1 and the third heat exchange circuit S3. By providing the communication branch 23, the flow rate or pressure of the first heat exchange medium in the first heat exchange circuit S1 and the third heat exchange circuit S3 can be adjusted.

[0038] In Figure 1 In the illustrated embodiment, the thermal management system 1 further includes a first expansion valve 24, which is provided upstream of the second heat exchanger 13 and is used to control the flow rate or pressure of the first heat exchange medium in the first heat exchange circuit S1. The thermal management system 1 further includes a second expansion valve 25, which is provided upstream of the third heat exchanger 17 and is used to control the flow rate or pressure of the first heat exchange medium in the third heat exchange circuit S3. The provision of the first expansion valve 24 and the second expansion valve 25 has a simple structure and low cost.

[0039] In Figure 1 In the illustrated embodiment, the thermal management system 1 further includes a plurality of power components 26, which are provided in the heat exchange circuit filled with the second heat exchange medium. The power component 26 can be a power water pump, which plays a driving role and can be provided in the heat exchange circuit filled with the second heat exchange medium to enhance the circulation speed of the second heat exchange medium. For example, the power component 26 is provided in the second heat exchange circuit S2 and can also be provided in the fourth heat exchange circuit S4. In Figure 1 In the illustrated embodiment, the thermal management system 1 further includes an expansion water tank 27, which is connected to the circuit filled with the second heat exchange medium to supply the second heat exchange medium to the circuit filled with the second heat exchange medium, ensuring the stable operation of the thermal management system 1.
