[0021] Reference below Figure 1-Figure 7 A thermal management system 100 according to an embodiment of the present invention is described, and the present invention also provides a vehicle.

[0022] The thermal management system 100 includes: a first control valve 61, the first control valve 61 is connected with a high-pressure heat exchange circuit 10, a battery heat exchange circuit 20, a radiator circuit 30 and a heat exchange circuit 40, and the first control valve 61 selectively connects one or more of the high-pressure heat exchange circuit 10, the battery heat exchange circuit 20, the radiator circuit 30 and the heat exchange circuit 40. The first control valve 61 includes: a plurality of valve ports, the plurality of valve ports are respectively connected with the high-pressure heat exchange circuit 10, the battery heat exchange circuit 20, the radiator circuit 30 and the heat exchange circuit 40, and by controlling the connection of the plurality of valve ports, one or more of the high-pressure heat exchange circuit 10, the battery heat exchange circuit 20, the radiator circuit 30 and the heat exchange circuit 40 are selectively connected.

[0023] The thermal management system 100 further includes: an air conditioning system, which exchanges heat with the heat exchanger circuit 40 and the heating circuit 50. The thermal management system 100 further includes: a heating circuit 50, which can be used for heating the passenger compartment. The air conditioning system and the heating circuit 50 exchange heat through the condenser 71, and the refrigerant and the coolant exchange heat at the condenser 71 to achieve heat exchange between the air conditioning system and the heating circuit 50.

[0024] For example, Figure 2 and Figure 3 As shown, the first control valve 61 can connect the radiator circuit 30 and the high-pressure heat exchange circuit 10, so that the radiator circuit 30 and the high-pressure heat exchange circuit 10 form a closed circuit, and the heat generated by the high-pressure device in the high-pressure heat exchange circuit 10 is brought to the radiator circuit 30 through the coolant, thereby realizing the heat dissipation of the high-pressure device.

[0025] And, if Figure 4 and Figure 5 As shown, the first control valve 61 can connect the two ends of the battery heat exchange circuit 20, forming a closed loop in the battery heat exchange circuit 20 to achieve uniform temperature of the battery pack 21.

[0026] For example, Figure 3 As shown, the first control valve 61 can connect the high-pressure heat exchange loop 10 and the battery heat exchange loop 20 in parallel and then connect them in series with the radiator 31. The high-pressure heat exchange loop 10 and the battery heat exchange loop 20 are connected in parallel and then connected in series with the radiator loop 30. The coolant flows between the radiator 31, the high-pressure heat exchange loop 10 and the battery heat exchange loop 20, so that the heat generated by the battery pack 21 and the high-voltage device can be transported to the radiator 31 and dissipated to the outside, thereby achieving heat dissipation of the battery pack 21 and the high-voltage device.

[0027] For example, Figure 4 As shown, the first control valve 61 can connect the battery heat exchange loop 20, the high-pressure heat exchange loop 10 and the heat exchanger loop 40. The battery heat exchange loop 20, the high-pressure heat exchange loop 10 and the heat exchanger loop 40 are connected in series with each other, and the battery heat exchange loop 20, the high-pressure heat exchange loop 10 and the heat exchanger loop 40 are connected in series to form a closed loop. The heat exchanger loop 40 exchanges heat with the air-conditioning system, and the refrigerant of the air-conditioning system absorbs the waste heat generated by the high-pressure device. When the condenser 71 is connected in series with the battery heat exchange loop 20, the heat can be used to heat the battery pack 21.

[0028] like Figure 2 As shown, the first control valve 61 can be connected in series with the heat exchanger circuit 40 and the battery heat exchange circuit 20. The heat exchanger circuit 40 can absorb the heat of the battery pack 21, and the heat exchanger circuit 40 transfers the heat to the air conditioning system, which can be used for heating the passenger compartment.

[0029] like Figure 2As shown, the first control valve 61 can connect the high-pressure heat exchange loop 10 and the heat exchanger loop 40. The heat generated by the high-pressure device is brought to the heat exchanger loop 40 through the coolant, and then the waste heat of the high-pressure device is recovered, and the waste heat can be used for defrosting in a cold environment; and because the heat exchanger loop 40 is connected to the air conditioning system, the heat at the heat exchanger loop 40 can be transferred to the condenser 71 through the refrigerant, thereby realizing heating of the passenger compartment.

[0030] The first control valve 61 is used to form at least one closed loop between the radiator 31, the heat exchanger 41, the battery heat exchange loop 20 and the high-pressure heat exchange loop 10, that is, the heat generated by the high-pressure heat exchange loop 10 or the battery heat exchange loop 20 can be transported to the remaining loops or devices, so that the heat generated by the thermal management system 100 can be effectively utilized.

[0033] The first control valve 61 includes: a first valve port, a second valve port, a third valve port, a fourth valve port, a fifth valve port, a sixth valve port, a seventh valve port, an eighth valve port and a ninth valve port.

[0038] The thermal management system 100 further includes: a fifth branch 87, a fifth branch 87, one end of the fifth branch 87 is connected to the first control valve 61, and the other end of the fifth branch 87 is connected to the other end of the first check valve 64 and one end of the second check valve 65. One end of the fifth branch 87 is connected to the sixth valve port, and the other end of the fifth branch 87 is connected to one end of the second check valve 65.

[0039] like Figure 2 and Figure 3 As shown, the fifth branch 87 connects the sixth valve port and one end of the second one-way valve 65, the first control valve 61 can connect the sixth valve port and the ninth valve port, the other end of the second one-way valve 65 is connected to the seventh valve port, and the first control valve 61 connects the seventh valve port and the eighth valve port, thereby, the radiator circuit 30 and the high-pressure heat exchange circuit 10 can be connected in series.

[0041] The thermal management system 100 further includes: a first stop valve 66, one end of which is connected to one end of the battery heat exchange loop 20, and the other end of which is connected to one end of the heat exchange loop 40.

The sixth branch 88 connects the third valve port and one end of the heat exchange loop 40. If the first control valve 61 connects the second valve port and the eighth valve port and connects the third valve port and the ninth valve port (such as Figure 4 As shown), the heat exchanger circuit 40, the high-pressure heat exchange circuit 10 and the radiator circuit 30 are connected in series, and the heat exchanger 41 can absorb the heat of the motor 11 and the ambient heat, which can be used for heating the passenger compartment or heating the battery.

[0042] The heating circuit 50 includes: a condenser 71, an electric heater 52 and a heater core 51. The electric heater 52 and the condenser 71 are connected in series. One end of the condenser 71 is selectively connected to the multi-way pipe 63 and one end of the heater core 51, and the other end of the condenser 71 is connected to one end of the electric heater 52. The other end of the electric heater 52 is connected to the other end of the heater core 51 and the first control valve 61. The refrigerant of the air-conditioning system can flow through the condenser 71, and the coolant of the heating circuit 50 can flow through the condenser 71, that is, the condenser 71 is not only a part of the air-conditioning system, but also a part of the heating circuit 50. In this way, when the air-conditioning system is running, the condenser 71 will generate heat, and thus the heat can be transferred to the battery heat exchange circuit 20 or the heater core 51 through the first control valve 61 and the second control valve 62 to achieve heating of the battery pack 21 or heating of the passenger compartment, so that the heat generated by the condenser 71 can be reasonably utilized; the radiator circuit 30 and the condenser 71 can also be connected in series through the first control valve 61 and the second control valve 62 to transfer heat to the radiator circuit 30, and the heat can be dissipated to the outside through the radiator 31 to achieve cooling of the condenser 71.

The refrigerant in the air conditioning system exchanges heat with the coolant at the heat exchanger 41, so that the refrigerant can absorb the heat of the battery heat exchange circuit 20 or the high-pressure heat exchange circuit 10 or the environment. The refrigerant flows out of the compressor 73 and releases heat at the condenser 71 . The refrigerant that has released heat absorbs heat at the evaporator 72 or the heat exchanger 41 and finally returns to the compressor 73 . When the passenger compartment is cooled, the refrigerant absorbs heat from the passenger compartment at the evaporator 72 , and the coolant flowing through the condenser 71 releases heat to the heating circuit 50 .

[0049] Furthermore, the heat exchanger 41 is connected in parallel with the evaporator 72, so that the refrigerant can flow to the heat exchanger 41 to absorb heat after releasing heat in the condenser 71. The heat absorbed by the refrigerant from the heat exchanger 41 can be used to be transferred to the heating circuit 50 at the condenser 71 for heating the passenger compartment; or, the refrigerant can flow to the evaporator 72 to absorb heat after releasing heat in the condenser 71.
