[0033] In order to meet the needs of rapid heat dissipation or heating, improve the driving experience, and eliminate safety risks, such as Figure 1 As shown, the utility model provides a thermal management system. The thermal management system includes a battery temperature control circuit 1, a first cooling circuit 2, a passenger compartment heating circuit 3 and a second cooling circuit 4.

[0034] Among them, the battery temperature control circuit 1 includes a first water pump 11, a first heater 12, a cooling water circuit of a battery 13 and a first evaporator 14 which are connected in series in sequence. The first cooling circuit 2 includes a first compressor 21 and a first condenser 22 which are connected to each other, and the first evaporator 14 is arranged in series between the first compressor 21 and the first condenser 22. The passenger compartment heating circuit 3 includes a second heater 31, a second evaporator 33 and a second water pump 34 which are connected in sequence, and the passenger compartment heating circuit 3 can be connected or disconnected with the battery temperature control circuit 1. The second cooling circuit 4 includes a second compressor 41 and a second condenser 42 which are connected to each other, and the second evaporator 33 is arranged in series between the second compressor 41 and the second condenser 42.

[0035] Under normal working conditions, the temperature of the battery 13 can be controlled by the battery temperature control circuit 1 and the first cooling circuit 2, and the temperature of the cab can be controlled by the passenger compartment heating circuit 3 and the second cooling circuit 4. When emergency heating or cooling is required, the passenger compartment heating circuit 3 is connected to the battery temperature control circuit 1, so that the first heater 12 and the second heater 31 can be used together to achieve rapid heating, or the first condenser 22 and the second condenser 42 can be used together to achieve rapid cooling, which can meet the needs of rapid heat dissipation or heating, improve the driving experience, and eliminate safety risks.

[0036] Furthermore, the thermal management system further includes a first three-way control valve 7, a first port of the first three-way control valve 7 is connected to the first evaporator 14, a second port of the first three-way control valve 7 is connected to the second heater 31 and the cooling water path of the battery 13, and a third port of the first three-way control valve 7 is connected to the second water pump 34. By controlling the first port and the third port of the first three-way control valve 7 to be connected, the battery temperature control circuit 1 and the passenger compartment heating circuit 3 can be connected. Through the above arrangement, it is convenient to control whether the battery temperature control circuit 1 and the passenger compartment heating circuit 3 are connected.

[0037] Furthermore, the thermal management system further includes a first three-way flow control valve 6, a first port of the first three-way flow control valve 6 is connected to the first evaporator 14, a second port of the first three-way flow control valve 6 is connected to the first port of the first three-way control valve 7, and a third port of the first three-way flow control valve 6 is connected to the cooling water path of the battery 13. By providing the first three-way flow control valve 6, the flow can be adjusted to further improve the control effect.

[0038] Furthermore, a heating core 32 is provided in series in the passenger compartment heating circuit 3, and the heating core 32 is located between the second heater 31 and the second evaporator 33. By providing the heating core 32, the coolant heated by the heater exchanges heat with the cab at the heating core 32, thereby increasing the temperature of the cab.

[0039] Furthermore, the thermal management system further includes an indoor evaporator 43, which is arranged in parallel with the second evaporator 33. By providing two sets of evaporators, the heat exchange area with the cab can be increased, so that when the cab is cooled, heat exchange can be performed quickly, so that the cab can be cooled quickly.

[0040] Furthermore, the thermal management system further includes a motor cooling circuit 5, which includes a motor 51, a third water pump 52 and a radiator 53 connected in series. The second water pump 34 can drive the cooling water circulation, thereby bringing the heat generated by the motor 51 into the radiator 53, and the radiator 53 performs heat exchange with the outside atmosphere, thereby reducing the temperature of the motor 51 and ensuring that the motor 51 can work normally.

[0041] Furthermore, the thermal management system further includes a second three-way flow control valve 8, wherein the first port of the second three-way flow control valve 8 is connected to the motor 51, the second port of the second three-way flow control valve 8 is connected to the second heater 31, and the third port of the second three-way flow control valve 8 is connected to the radiator 53. By controlling the first port and the second port of the second three-way flow control valve 8 to be connected, the motor cooling circuit 5 can be connected to the passenger compartment heating circuit 3, and the passenger compartment can be heated by the cooling water with a higher temperature in the motor cooling circuit 5, so that the heat generated by the motor 51 can be fully utilized to reduce energy consumption. By adjusting the opening of the second three-way flow control valve 8, the amount of cooling water flowing between the motor cooling circuit 5 and the passenger compartment heating circuit 3 can be adjusted. When the first port and the third port of the second three-way flow control valve are connected, the motor cooling circuit 5 and the passenger compartment heating circuit 3 operate independently without affecting each other.

[0042] Furthermore, the thermal management system further includes a second three-way control valve 9, a first port of the second three-way control valve 9 is connected to the radiator 53, a second port of the second three-way control valve 9 is connected to the third port of the second three-way control flow valve 8, and the third port of the second three-way control valve 9 is connected to the third water pump 52. By setting the second three-way control valve 9, when the first port of the second three-way control valve 9 is connected to the second port, the cooling water for cooling the motor 51 is dissipated through the radiator 53. When the second port of the second three-way control valve 9 is connected to the third port, the cooling water does not pass through the radiator 53. When the motor 51 is started, the cooling water is kept at a relatively high temperature, so that the motor 51 can be started efficiently.

[0043] Furthermore, the thermal management system further includes a third three-way control valve 10, a first port of the third three-way control valve 10 is connected to a second port of the second three-way control flow valve 8, a second port of the third three-way control valve 10 is connected to an end of the cooling water path of the battery 13 away from the heater, and a third port of the third three-way control valve 10 is connected to a third port of the second three-way control flow valve 8. By providing the third three-way control valve 10, the control mode of the thermal management system can be further enriched. When the motor 51 needs to be quickly heated or cooled, the battery temperature control circuit 1 can be connected to the motor cooling circuit 5, so that the battery 13 can be heated or the battery 13 can be cooled using the radiator 53.

[0044] Furthermore, fans are provided on one side of the first condenser 22 and the second condenser 42 , and the fans can accelerate air circulation, thereby facilitating rapid cooling of the first condenser 22 and the second condenser 42 .

[0045] This thermal management system can use the battery temperature control circuit 1 and the first cooling circuit 2 to cooperate to cool the battery 13, and the battery 13 can be heated by turning on the first heater 12. By turning on the second heater 31, the passenger compartment heating circuit 3 can be used to heat the passenger compartment; by cooperating with the passenger heating circuit and the second cooling circuit 4, the passenger compartment can be cooled. By connecting the battery temperature control circuit 1 with the passenger compartment heating circuit 3, rapid heating can be achieved. When the battery temperature control circuit 1 is connected to the passenger compartment heating circuit 3, and cooperates with the first cooling circuit 2 and the second cooling circuit 4, rapid cooling can be achieved. The motor cooling circuit 5 can operate independently to cool the motor 51; the motor cooling circuit 5 can also be connected to the passenger compartment heating circuit 3 and / or the battery temperature control circuit 1 to enhance the heating or cooling effect.

[0046] This embodiment also provides a vehicle, including a vehicle body and the above thermal management system. The thermal management system is arranged in the vehicle body and can meet the needs of rapid heat dissipation or heating, improve driving experience, and eliminate safety risks.
