[0069] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0070] The following describes a thermal management system 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0071] like Figure 1 As shown, the thermal management system 100 according to the embodiment of the present invention includes a first heat exchanger 7 , a second heat exchanger 6 , a compressor 1 and a fluorine pump 4 .

[0072] The first heat exchanger 7 is used to adjust the temperature of the passenger compartment, the second heat exchanger 6 is used to exchange heat with the battery pack, the compressor 1 and the fluorine pump 4 can be switchably connected to the first heat exchanger 7, and the compressor 1 and the fluorine pump 4 can be switchably connected to the second heat exchanger 6.

[0073] Compressor 1 is used to compress the refrigerant and drive it to flow, thereby using the refrigerant to achieve cooling or heating. When the first heat exchanger 7 is connected to compressor 1, the compressor 1 drives the refrigerant to flow through the first heat exchanger 7, which can achieve cooling or heating of the passenger compartment. When the second heat exchanger 6 is connected to compressor 1, the compressor 1 drives the refrigerant to flow through the second heat exchanger 6, which can achieve heating or cooling of the battery pack.

[0074] Fluorine pump 4 is used to drive the circulation of refrigerant. Specifically, when the ambient temperature is low, the refrigerant is suitable for heat exchange with the ambient temperature, releasing heat in the environment and becoming a cooler refrigerant. Fluorine pump 4 is connected to first heat exchanger 7. When fluorine pump 4 drives the refrigerant through first heat exchanger 7, the cooler refrigerant can cool the passenger compartment. Fluorine pump 4 is connected to second heat exchanger 6. When fluorine pump 4 drives the refrigerant through second heat exchanger 6, the cooler refrigerant can cool the battery pack.

[0075] Specifically, while the first heat exchanger 7 is used to cool the passenger compartment, it can also dehumidify the passenger compartment. When the ambient temperature is low, when the driver and passengers enter the passenger compartment, their breathing and other factors increase the humidity inside the passenger compartment. When the dew point of the air on the inner surface of the glass is higher than the glass temperature, the glass fogs up, which can affect the driver's vision. Therefore, dehumidification of the passenger compartment is essential.

[0076] When the first heat exchanger 7 is used to cool the passenger compartment, the low temperature on the surface of the first heat exchanger 7 can be used to achieve the purpose of condensation and dehumidification, thereby reducing the humidity inside the entire passenger compartment. When the humidity inside the passenger compartment decreases, the dew point temperature of the air on the corresponding glass surface decreases, thereby reducing the risk of glass fogging.

[0077] It should be noted here that the first heat exchanger 7 and the second heat exchanger 6 may both be connected to the compressor 1 and disconnected from the fluorine pump 4, so that the compressor 1 can be used to cool or heat the battery pack and the passenger compartment; the first heat exchanger 7 and the second heat exchanger 6 may both be connected to the fluorine pump 4 and disconnected from the compressor 1, so that the fluorine pump 4 can be used to cool the battery pack and the passenger compartment; or one of the first heat exchanger 7 and the second heat exchanger 6 may be connected to the compressor 1 and disconnected from the fluorine pump 4, and the other of the first heat exchanger 7 and the second heat exchanger 6 may be connected to the fluorine pump 4 and disconnected from the compressor 1, so that the compressor 1 can be used to heat or cool one of them, and the fluorine pump 4 can be used to cool the other one.

[0078] Specifically, either the fluorine pump 4 or the compressor 1 can be working, or the fluorine pump 4 and the compressor 1 can be working at the same time without affecting each other. When the fluorine pump 4 and the compressor 1 are working at the same time, the refrigerant flowing through the fluorine pump 4 and the refrigerant flowing through the compressor 1 are located in two different flow paths and do not affect each other.

[0079] Among them, when the compressor 1 is in the refrigeration cycle, the gas at the exhaust port needs to be increased to a higher pressure to realize the heat transfer function. In the refrigeration cycle of the fluorine pump 4, the driving force of the fluorine pump 4 on the liquid refrigerant is only used to overcome the resistance of the system flow path. Therefore, the power of the fluorine pump 4 is much lower than the power of the compressor 1.

[0080] By using the fluorine pump 4 to drive the flow of refrigerant, the passenger compartment and the second heat exchanger 6 can be cooled by using the refrigerant with a lower temperature after heat exchange with the environment. In this way, the fluorine pump 4 can replace some of the refrigeration working conditions of the compressor 1, thereby reducing the frequency of use of the compressor 1, increasing the service life of the compressor 1, reducing the energy consumption of the thermal management system 100, and saving resources.

[0081] According to the thermal management system 100 of the embodiment of the present invention, the compressor 1 and the fluorine pump 4 can work simultaneously, so as to make full use of the fluorine pump 4 to replace the refrigeration of the compressor 1 in some working conditions. For example, the fluorine pump 4 is used to cool the passenger compartment and the battery pack, so as to reduce the frequency of use of the compressor 1, increase the service life of the compressor 1, reduce the energy consumption of the thermal management system 100, and save resources.

[0082] The following describes a thermal management system 100 according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0083] In some specific embodiments of the present invention, Figure 1 As shown, the thermal management system 100 according to the embodiment of the present invention includes a first heat exchanger 7 , a second heat exchanger 6 , a compressor 1 and a fluorine pump 4 .

[0084] In some embodiments of the present invention, Figure 1 、 Figure 2 As shown, the compressor 1 has an exhaust port and an intake port, and the intake port is selectively connected to the first heat exchanger 7 to enable the passenger compartment to be cooled by the compressor 1. The thermal management system 100 also includes an in-vehicle condenser 5, and the exhaust port is selectively connected to the in-vehicle condenser 5 to heat the passenger compartment.

[0085] Driven by the compressor 1, the refrigerant flows through the in-vehicle condenser 5 and the first heat exchanger 7 in sequence. The high-temperature and high-pressure gaseous refrigerant discharged from the exhaust port of the compressor 1 releases heat at the in-vehicle condenser 5 when flowing through the in-vehicle condenser 5 to heat the passenger compartment. The refrigerant flowing through the in-vehicle condenser 5 flows to the first heat exchanger 7, and the refrigerant absorbs heat in the first heat exchanger 7 to cool part of the passenger compartment, thereby achieving dehumidification of the passenger compartment.

[0086] That is to say, compressor 1 can simultaneously achieve heating and dehumidification of the passenger compartment. Specifically, when the ambient temperature is low, the passenger compartment needs to be heated to improve the comfort of the driver and passengers. However, due to the increase in humidity in the car, the dew point temperature of the air on the inner surface of the window is higher than the glass temperature, and the glass will fog up, so dehumidification is required. Therefore, dehumidification and heating must coexist.

[0087] In some embodiments, as Figure 2As shown, a first throttle member 26 is provided between the in-vehicle condenser 5 and the first heat exchanger 7. The compressor 1 is used to compress the gaseous refrigerant to form a high-temperature and high-pressure gaseous refrigerant. When the high-temperature and high-pressure gaseous refrigerant flows through the in-vehicle condenser 5, it is suitable for releasing heat at the in-vehicle condenser 5, and the high-temperature and high-pressure gaseous refrigerant becomes a high-temperature liquid refrigerant. The high-temperature liquid refrigerant becomes a low-temperature liquid refrigerant after flowing through the first throttle member 26. When the low-temperature liquid refrigerant flows through the first heat exchanger 7, it absorbs heat at the first heat exchanger 7 to achieve cooling of part of the passenger compartment, thereby achieving cooling and dehumidification treatment of the passenger compartment.

[0088] In some specific embodiments of the present invention, Figure 3 As shown, the thermal management system 100 includes a first mode. In the first mode, the exhaust port is connected to the in-vehicle condenser 5 to heat the passenger compartment, and the fluorine pump 4 is connected to the first heat exchanger 7 to cool and dehumidify the passenger compartment. The compressor 1 is used to heat the in-vehicle condenser 5, and the fluorine pump 4 is used to cool and dehumidify the first heat exchanger 7, thereby dehumidifying the passenger compartment while heating the passenger compartment.

[0089] Among them, compared with making the compressor 1 drive the refrigerant to flow through the in-vehicle condenser 5 and the first heat exchanger 7 in sequence, the compressor 1 is used to simultaneously realize heating of the in-vehicle condenser 5 and cooling and dehumidification of the first heat exchanger 7, so that the compressor 1 drives the refrigerant to flow through the in-vehicle condenser 5, and the fluorine pump 4 drives the refrigerant to flow through the first heat exchanger 7, and the compressor 1 is used to realize heating of the in-vehicle condenser 5, and the fluorine pump 4 is used to realize cooling and dehumidification of the first heat exchanger 7. In this way, the refrigerant driven by the compressor 1 does not need to flow through the first heat exchanger 7 when flowing through the in-vehicle condenser 5, so as to reduce the gas temperature difference between the exhaust port and the intake port of the compressor 1, and to save the energy consumption of the compressor 1.

[0090] In some specific embodiments of the present invention, Figure 1 As shown, the thermal management system 100 includes a first refrigerant flow path 31 and a second refrigerant flow path 32, the first refrigerant flow path 31 and the second refrigerant flow path 32 are connected in parallel, one end of the first heat exchanger 7 is switchably connected to one end of the first refrigerant flow path 31 and one end of the second refrigerant flow path 32, the other end of the first heat exchanger 7 is switchably connected to the other end of the first refrigerant flow path 31 and the other end of the second refrigerant flow path 32, one end of the in-vehicle condenser 5 is connected to the other end of the second refrigerant flow path 32, and the other end of the in-vehicle condenser 5 is connected to one end of the second refrigerant flow path 32.

[0091] The fluorine pump 4 is connected to the first refrigerant flow path 31, and the compressor 1 is connected to the second refrigerant flow path 32, so that the fluorine pump 4 and the compressor 1 can work independently, so that the refrigerant driven by the fluorine pump 4 and the refrigerant driven by the compressor 1 do not interfere with each other.

[0092] Specifically, in the first mode, as Figure 3 As shown, one end of the first heat exchanger 7 is connected to one end of the first refrigerant flow path 31, and the other end of the first heat exchanger 7 is connected to the other end of the first refrigerant flow path 31. One end of the in-vehicle condenser 5 is connected to one end of the second refrigerant flow path 32, and the other end of the in-vehicle condenser 5 is connected to the other end of the second refrigerant flow path 32. The fluorine pump 4 drives the refrigerant to circulate between the first refrigerant flow path 31 and the first heat exchanger 7, and the compressor 1 drives the refrigerant to circulate between the second refrigerant flow path 32 and the in-vehicle condenser 5.

[0093] Or, as Figure 2 As shown, one end of the first heat exchanger 7 is connected to the other end of the second refrigerant flow path 32, and the other end of the first heat exchanger 7 is connected to one end of the second refrigerant flow path 32. One end of the in-vehicle condenser 5 is connected to the other end of the second refrigerant flow path 32, and the other end of the in-vehicle condenser 5 is connected to the other end of the first heat exchanger 7. The compressor 1 drives the refrigerant to circulate between the second refrigerant flow path 32, the in-vehicle condenser 5, and the first heat exchanger 7.

[0094] In some optional embodiments of the present invention, Figure 4 As shown, the thermal management system 100 includes a second mode. In the second mode, the exhaust port is connected to the in-vehicle condenser 5 to heat the passenger compartment, and the fluorine pump 4 is connected to the second heat exchanger 6 to cool the battery pack, so as to utilize the compressor 1 to heat the passenger compartment and utilize the fluorine pump 4 to cool the battery pack.

[0095] In some optional embodiments of the present invention, Figure 5 As shown, the exhaust port is connected to the in-vehicle condenser 5 to heat the passenger compartment, and the intake port is connected to the second heat exchanger 6 to cool the battery pack, so as to utilize the compressor 1 to heat the passenger compartment and cool the battery pack at the same time.

[0096] In some embodiments, as Figure 5 As shown, a second throttling member 24 is provided between the in-vehicle condenser 5 and the second heat exchanger 6. The compressor 1 is used to compress the gaseous refrigerant to form a high-temperature and high-pressure gaseous refrigerant. When the high-temperature and high-pressure gaseous refrigerant flows through the in-vehicle condenser 5, it is suitable for releasing heat at the in-vehicle condenser 5, and the high-temperature and high-pressure gaseous refrigerant becomes a high-temperature liquid refrigerant. The high-temperature liquid refrigerant becomes a low-temperature liquid refrigerant after flowing through the second throttling member 24. When the low-temperature liquid refrigerant flows through the second heat exchanger 6, it absorbs heat at the second heat exchanger 6 to achieve cooling of part of the passenger compartment and cooling of the battery pack at the same time.

[0097] Among them, compared with making the compressor 1 drive the refrigerant to flow through the in-vehicle condenser 5 and the second heat exchanger 6 in sequence, the compressor 1 is used to simultaneously realize heating of the in-vehicle condenser 5 and cooling of the second heat exchanger 6, so that the compressor 1 drives the refrigerant to flow through the in-vehicle condenser 5, and the fluorine pump 4 drives the refrigerant to flow through the second heat exchanger 6, and the compressor 1 is used to heat the in-vehicle condenser 5, and the fluorine pump 4 is used to cool the second heat exchanger 6. In this way, the refrigerant driven by the compressor 1 does not need to flow through the second heat exchanger 6 after flowing through the in-vehicle condenser 5, so as to reduce the gas temperature difference between the exhaust port and the intake port of the compressor 1, and to save the energy consumption of the compressor 1.

[0098] In some specific embodiments of the present invention, Figure 4 、 Figure 5 As shown, the thermal management system 100 includes a first refrigerant flow path 31 and a second refrigerant flow path 32, the first refrigerant flow path 31 and the second refrigerant flow path 32 are connected in parallel, one end of the second heat exchanger 6 is switchably connected to one end of the first refrigerant flow path 31 and one end of the second refrigerant flow path 32, the other end of the second heat exchanger 6 is switchably connected to the other end of the first refrigerant flow path 31 and the other end of the second refrigerant flow path 32, one end of the in-vehicle condenser 5 is connected to the other end of the second refrigerant flow path 32, and the other end of the in-vehicle condenser 5 is connected to one end of the second refrigerant flow path 32.

[0099] The fluorine pump 4 is connected to the first refrigerant flow path 31, and the compressor 1 is connected to the second refrigerant flow path 32, so that the fluorine pump 4 and the compressor 1 can work independently, so that the refrigerant driven by the fluorine pump 4 and the refrigerant driven by the compressor 1 do not interfere with each other.

[0100] Specifically, in the second mode, as Figure 4 As shown, one end of the second heat exchanger 6 is connected to one end of the first refrigerant flow path 31, and the other end of the second heat exchanger 6 is connected to the other end of the first refrigerant flow path 31. One end of the in-vehicle condenser 5 is connected to the other end of the second refrigerant flow path 32, and the other end of the in-vehicle condenser 5 is connected to one end of the second refrigerant flow path 32. The fluorine pump 4 drives the refrigerant to circulate between the first refrigerant flow path 31 and the second heat exchanger 6, and the compressor 1 drives the refrigerant to circulate between the second refrigerant flow path 32 and the in-vehicle condenser 5.

[0101] Or, as Figure 5 As shown, one end of the second heat exchanger 6 is connected to one end of the second refrigerant flow path 32, and the other end of the second heat exchanger 6 is connected to the other end of the second refrigerant flow path 32. One end of the in-vehicle condenser 5 is connected to the other end of the second refrigerant flow path 32, and the other end of the in-vehicle condenser 5 is connected to the other end of the second heat exchanger 6. The compressor 1 drives the refrigerant to circulate between the second refrigerant flow path 32, the in-vehicle condenser 5, and the second heat exchanger 6.

[0102] In some embodiments of the present invention, Figure 6 、 Figure 7 As shown, the compressor 1 has an exhaust port and an intake port, which are switchably connected to the second heat exchanger 6 to heat or cool the battery pack.

[0103] like Figure 6 As shown, in this embodiment, the exhaust port is connected to the second heat exchanger 6. At this time, the high-temperature and high-pressure gaseous refrigerant flowing out of the exhaust port of the compressor 1 is suitable for releasing heat at the second heat exchanger 6 when flowing through the second heat exchanger 6, thereby heating the battery pack.

[0104] In some embodiments, as Figure 6 As shown, the thermal management system 100 also includes a fourth heat exchanger 10 and a loop flow channel. The fourth heat exchanger 10 includes a first flow channel and a second flow channel. The loop flow channel includes the first flow channel. One end of the second flow channel is connected to the other end of the second heat exchanger 6, and the other end of the second flow channel is connected to the air intake of the compressor 1. A third throttling device 22 is provided between the second heat exchanger 6 and the fourth heat exchanger 10.

[0105] The compressor 1 is used to compress the gaseous refrigerant to form a high-temperature and high-pressure gaseous refrigerant. When the high-temperature and high-pressure gaseous refrigerant flows through the second heat exchanger 6, it is suitable for releasing heat at the second heat exchanger 6, and the high-temperature and high-pressure gaseous refrigerant becomes a high-temperature liquid refrigerant. The high-temperature liquid refrigerant becomes a low-temperature liquid refrigerant after flowing through the third throttling element 22. When the low-temperature liquid refrigerant flows through the second flow path of the fourth heat exchanger 10, it absorbs heat at the fourth heat exchanger 10 to absorb the heat in the heat exchange medium in the first flow path.

[0106] Specifically, the loop flow channel also includes a water pump 15, which is used to drive the circulation of the heat exchange medium. The loop flow channel includes a heat exchange flow channel for exchanging heat with the motor 14. When the low-temperature heat exchange medium flows through the heat exchange flow channel, it is suitable for taking away the heat from the motor 14. When the refrigerant absorbs the heat in the heat exchange medium in the first flow path at the fourth heat exchanger 10, the heat generated by the motor 14 can be utilized. For example, when the refrigerant flows through the second heat exchanger 6 after the refrigerant, this part of the heat can be used to heat the battery pack.

[0107] Furthermore, the circuit flow path also includes a radiator 12. The first flow path is switchably connected to the radiator 12 and the heat exchange flow path via a three-way valve 11. Specifically, when the first flow path is connected to the radiator 12, a water pump 15 drives the heat exchange medium to circulate within the first flow path, radiator 12, and heat exchange flow path. The heat absorbed by the heat exchange medium in the heat exchange flow path is dissipated at the radiator 12, thereby dissipating heat from the motor 14. A fan 13 is provided at the radiator 12 to improve the heat dissipation efficiency of the radiator 12.

[0108] When the first flow path is connected to the heat exchange medium, the water pump 15 drives the heat exchange medium to circulate between the first flow path and the heat exchange flow path. At this time, the heat absorbed by the heat exchange medium at the heat exchange flow path is suitable for heat exchange with the refrigerant in the second flow path at the fourth heat exchanger 10, so as to transfer the heat generated by the motor 14 to the refrigerant, so as to facilitate subsequent work using the heat generated by the motor 14, such as using the heat generated by the motor 14 to heat the passenger compartment or heat the battery pack.

[0109] like Figure 7 As shown, in this embodiment, the air intake is connected to the second heat exchanger 6. When the low-temperature and low-pressure liquid refrigerant flows through the second heat exchanger 6, it is suitable for absorbing heat at the second heat exchanger 6, thereby cooling the battery pack.

[0110] In some embodiments, as Figure 7 As shown, the thermal management system 100 also includes an off-vehicle condenser 2, which is arranged between the exhaust port of the compressor 1 and the second heat exchanger 6. A second throttling device 24 is provided between the off-vehicle condenser 2 and the second heat exchanger 6. The compressor 1 is used to compress the gaseous refrigerant to form a high-temperature and high-pressure gaseous refrigerant. When the high-temperature and high-pressure gaseous refrigerant flows through the off-vehicle condenser 2, it is suitable for releasing heat at the off-vehicle condenser 2, and the high-temperature and high-pressure gaseous refrigerant becomes a high-temperature liquid refrigerant. The high-temperature liquid refrigerant becomes a low-temperature liquid refrigerant after flowing through the second throttling device 24. When the low-temperature liquid refrigerant flows through the second heat exchanger 6, it absorbs heat at the second heat exchanger 6 to achieve cooling of the battery pack.

[0111] In some specific embodiments of the present invention, Figure 8 As shown, the thermal management system 100 also includes a third mode. In the third mode, the exhaust port is connected to the second heat exchanger 6, and the fluorine pump 4 is connected to the first heat exchanger 7, so as to utilize the compressor 1 to heat the battery pack and utilize the fluorine pump 4 to cool the passenger compartment.

[0112] In some specific embodiments of the present invention, Figure 9 As shown, the exhaust port is connected to one end of the second heat exchanger 6 , the other end of the second heat exchanger 6 is connected to the other end of the first heat exchanger 7 , and one end of the first heat exchanger 7 is connected to the air inlet of the compressor 1 .

[0113] A first throttling member 26 is provided between the other end of the second heat exchanger 6 and the other end of the first heat exchanger 7. The compressor 1 is used to compress the gaseous refrigerant to form a high-temperature and high-pressure gaseous refrigerant. When the high-temperature and high-pressure gaseous refrigerant flows through the first heat exchanger 7, it is suitable for releasing heat at the first heat exchanger 7, and the high-temperature and high-pressure gaseous refrigerant becomes a high-temperature liquid refrigerant. The high-temperature liquid refrigerant becomes a low-temperature liquid refrigerant after flowing through the first throttling member 26. When the low-temperature liquid refrigerant flows through the first heat exchanger 7, it absorbs heat at the first heat exchanger 7 to achieve heating of the battery pack and cooling of the passenger compartment.

[0114] Among them, compared with allowing the compressor 1 to drive the refrigerant to flow through the first heat exchanger 7 and the second heat exchanger 6 in sequence, the compressor 1 is used to simultaneously realize heating of the first heat exchanger 7 and cooling of the second heat exchanger 6, so that the compressor 1 drives the refrigerant to flow through the first heat exchanger 7, and the fluorine pump 4 drives the refrigerant to flow through the second heat exchanger 6, and the compressor 1 is used to realize heating of the first heat exchanger 7, and the fluorine pump 4 is used to realize cooling of the second heat exchanger 6. In this way, the refrigerant driven by the compressor 1 does not need to flow through the first heat exchanger 7 after flowing through the second heat exchanger 6, which is convenient for reducing the gas temperature difference between the exhaust port and the intake port of the compressor 1, and saving the energy consumption of the compressor 1.

[0115] In some embodiments of the present invention, Figure 10 As shown, the thermal management system 100 also includes a fourth mode. In the fourth mode, the fluorine pump 4 is connected to the first heat exchanger 7 and the second heat exchanger 6 respectively to achieve cooling of the battery pack and refrigeration of the passenger compartment.

[0116] Specifically, in the fourth mode, one end of the fluorine pump 4 is respectively connected to one end of the first heat exchanger 7 and one end of the second heat exchanger 6, and the other end of the fluorine pump 4 is respectively connected to the other end of the first heat exchanger 7 and the other end of the second heat exchanger 6. When the fluorine pump 4 drives the refrigerant with a lower temperature to flow through the first heat exchanger 7 and the second heat exchanger 6 respectively, the refrigerant with a lower temperature can be used to cool the first heat exchanger 7 and the second heat exchanger 6, thereby cooling the battery pack and the passenger compartment.

[0117] In some optional embodiments of the present invention, Figure 10 As shown, in the fourth mode, the first heat exchanger 7 and the second heat exchanger 6 are arranged in parallel, so that under the drive of the fluorine pump 4, a part of the refrigerant can be driven to flow to the first heat exchanger 7, and the other part of the refrigerant can be driven to flow to the second heat exchanger 6, thereby realizing cooling of the first heat exchanger 7 and the second heat exchanger 6.

[0118] In some embodiments of the present invention, the thermal management system 100 also includes a storage box and a third heat exchanger 8. The third heat exchanger 8 is used to adjust the temperature inside the storage box. The compressor 1 can be switchably connected to the third heat exchanger 8 to achieve cooling of the third heat exchanger 8 by the compressor 1, and then the third heat exchanger 8 is used to achieve cooling of the storage box, so as to reduce the temperature inside the storage box and enable the storage box to be used as a refrigerator.

[0119] like Figure 11 As shown, in this embodiment, one end of the third heat exchanger 8 is connected to the air inlet of the compressor 1. When the low-temperature and low-pressure refrigerant flows through the third heat exchanger 8, it is suitable for absorbing heat at the third heat exchanger 8 to achieve cooling of the storage box.

[0120] Furthermore, the thermal management system 100 also includes an outdoor condenser 2, which is arranged between the exhaust port of the compressor 1 and the third heat exchanger 8. A fourth throttling device 27 is provided between the outdoor condenser 2 and the third heat exchanger 8. The compressor 1 is used to compress the gaseous refrigerant to form a high-temperature and high-pressure gaseous refrigerant. When the high-temperature and high-pressure gaseous refrigerant flows through the outdoor condenser 2, it is suitable for releasing heat at the outdoor condenser 2, and the high-temperature and high-pressure gaseous refrigerant becomes a high-temperature liquid refrigerant. The high-temperature liquid refrigerant becomes a low-temperature liquid refrigerant after flowing through the fourth throttling device 27. When the low-temperature liquid refrigerant flows through the third heat exchanger 8, it absorbs heat at the third heat exchanger 8 to achieve cooling of the storage box.

[0121] In some examples, such as Figure 12 As shown, while compressor 1 is used to cool third heat exchanger 8, the passenger compartment can also be cooled simultaneously. Compressor 1 drives high-temperature, high-pressure refrigerant through external condenser 2 and then flows to first and third heat exchangers 7 and 8. After releasing heat at external condenser 2, a portion of the refrigerant flows through first throttle 26 and then flows to first heat exchanger 7. This refrigerant absorbs heat from first heat exchanger 7, thereby cooling and dehumidifying the passenger compartment. Another portion of the refrigerant flows through third throttle 22 and then flows to third heat exchanger 8. This refrigerant absorbs heat from third heat exchanger 8, thereby cooling the storage compartment.

[0122] In some examples, such as Figure 13 As shown, when the compressor 1 is used to cool the third heat exchanger 8, the passenger compartment can also be heated at the same time. The compressor 1 drives the high-temperature and high-pressure refrigerant to flow through the in-vehicle condenser 5 and then to the third heat exchanger 8. The high-temperature refrigerant releases heat at the in-vehicle condenser 5 to heat the passenger compartment, and the low-temperature refrigerant absorbs heat at the third heat exchanger 8 to cool the storage box.

[0123] In some examples, such as Figure 14As shown, while compressor 1 is used to cool the third heat exchanger 8, it can also simultaneously cool the battery pack. Compressor 1 drives the high-temperature, high-pressure refrigerant through the external condenser 2 and then flows to the second heat exchanger 6 and the third heat exchanger 8. After releasing heat at the external condenser 2, a portion of the refrigerant flows through the second throttle member 24 and then flows to the second heat exchanger 6. The refrigerant is suitable for absorbing heat from the second heat exchanger 6, thereby cooling the battery pack. The remaining portion of the refrigerant flows through the third throttle member 22 and then flows to the third heat exchanger 8. The refrigerant is suitable for absorbing heat from the third heat exchanger 8, thereby cooling the storage compartment.

[0124] In some examples, such as Figure 15 As shown, when the compressor 1 is used to cool the third heat exchanger 8, the battery pack can also be heated at the same time. The compressor 1 drives the high-temperature and high-pressure refrigerant to flow to the third heat exchanger 8 after passing through the second heat exchanger 6. The high-temperature refrigerant releases heat at the second heat exchanger 6 to heat the battery pack, and the low-temperature refrigerant absorbs heat at the third heat exchanger 8 to cool the storage box.

[0125] In some examples, such as Figure 16 As shown, while using compressor 1 to cool the third heat exchanger 8, it can also simultaneously cool the passenger compartment and the battery pack. Compressor 1 drives high-temperature, high-pressure refrigerant through the external condenser 2, then flows to the first heat exchanger 7, the second heat exchanger 6, and the third heat exchanger 8. After releasing heat at the external condenser 2, a portion of the refrigerant flows through the first throttle 26 and flows to the first heat exchanger 7. The refrigerant absorbs heat from the first heat exchanger 7, thereby cooling the passenger compartment. A portion of the refrigerant flows through the second throttle 24 and flows to the second heat exchanger 6. The refrigerant absorbs heat from the second heat exchanger 6, thereby cooling the battery pack. Another portion of the refrigerant flows through the third throttle 22 and flows to the third heat exchanger 8.

[0126] In some examples, such as Figure 17 As shown, when the compressor 1 is used to cool the third heat exchanger 8, the passenger compartment can also be cooled and the battery pack can be heated at the same time. The compressor 1 drives the high-temperature and high-pressure refrigerant to flow through the second heat exchanger 6 and then to the third heat exchanger 8 and the first heat exchanger 7. The high-temperature refrigerant releases heat at the second heat exchanger 6 to heat the battery pack, and the low-temperature refrigerant absorbs heat at the third heat exchanger 8 to cool the storage box. The low-temperature refrigerant absorbs heat at the first heat exchanger 7 to cool the passenger compartment.

[0127] In some examples, such as Figure 18As shown, when the compressor 1 is used to cool the third heat exchanger 8, the heating of the passenger compartment and the cooling and dehumidification of the passenger compartment can also be achieved at the same time. The compressor 1 drives the high-temperature and high-pressure refrigerant to flow through the in-vehicle condenser 5 and then to the third heat exchanger 8 and the first heat exchanger 7. The high-temperature refrigerant releases heat at the in-vehicle condenser 5 to heat the passenger compartment; the low-temperature refrigerant absorbs heat at the third heat exchanger 8 to cool the storage box; and the low-temperature refrigerant absorbs heat at the first heat exchanger 7 to cool and dehumidify the passenger compartment.

[0130] like Figure 20 As shown, in this embodiment, the third heat exchanger 8 is connected to the fluorine pump 4. When the low-temperature and low-pressure refrigerant flows through the third heat exchanger 8, it is suitable for absorbing heat at the third heat exchanger 8 to achieve cooling of the storage box.

[0131] In some examples, such as Figure 21 As shown, while the fluorine pump 4 is used to cool the storage box, the passenger compartment can also be cooled. The first heat exchanger 7 and the third heat exchanger 8 are both connected to the fluorine pump 4. The fluorine pump 4 drives the refrigerant to flow to the first heat exchanger 7 and the third heat exchanger 8 respectively. The low-temperature refrigerant absorbs heat at the first heat exchanger 7 to cool the passenger compartment, and the low-temperature refrigerant absorbs heat at the third heat exchanger 8 to cool the storage box.

The low-temperature refrigerant absorbs heat at the second heat exchanger 6 to cool the battery pack, and the low-temperature refrigerant absorbs heat at the third heat exchanger 8 to cool the storage box.

[0133] In some examples, such as Figure 23 As shown, while the fluorine pump 4 is used to cool the storage box, the battery pack and the passenger compartment can also be cooled. The first heat exchanger 7, the second heat exchanger 6 and the third heat exchanger 8 are all connected to the fluorine pump 4. The fluorine pump 4 drives the refrigerant to flow to the first heat exchanger 7, the second heat exchanger 6 and the third heat exchanger 8 respectively. The low-temperature refrigerant absorbs heat at the first heat exchanger 7 to cool the passenger compartment; the low-temperature refrigerant absorbs heat at the second heat exchanger 6 to cool the battery pack; the low-temperature refrigerant absorbs heat at the third heat exchanger 8 to cool the storage box.

[0138] In summary, it can be concluded that compressor 1 can be used to cool and heat second heat exchanger 6, thereby cooling and heating the battery pack. Compressor 1 can also be used to cool first and third heat exchangers 7, 8, thereby cooling the passenger compartment and storage compartment. Fluorine pump 4 can be used to cool part or all of first, second, and third heat exchangers 7, 6, 8.
