[0059] like Figure 8As shown, the automobile thermal management device has a single-passenger cooling function, and the single-passenger cooling function can realize passenger compartment cooling through refrigerant circulation. When the automobile thermal management device turns on the single-passenger cooling function, the first stop valve 422 and the first expansion valve 432 are in an open state, the second stop valve 437, the third stop valve 425, the fourth stop valve 426, the second expansion valve 434 and the third expansion valve 424 are in a closed state, and the sixth port 136 of the six-way valve 13 is connected to the fourth port 134 of the six-way valve 13. The low-temperature and low-pressure gas refrigerant is compressed by the compressor 431 to become a high-temperature and high-pressure gas refrigerant.

The refrigeration principle of the passenger compartment with the mixed refrigeration function is the same as the principle of the passenger compartment refrigeration function mentioned above, wherein, after the high-temperature and high-pressure liquid refrigerant flows to the first refrigerant tee 441, it is divided into two parts by the first refrigerant tee 441, one part of the high-temperature and high-pressure liquid refrigerant flows to the first expansion valve 432 to continue the passenger compartment refrigeration cycle, and the other part of the high-temperature and high-pressure liquid refrigerant flows to the second expansion valve 434, and the high-temperature and high-pressure liquid refrigerant is throttled into a medium-pressure gas-liquid mixture at the second expansion valve 434, and the medium-pressure gas-liquid mixture flows from the refrigerant outlet of the second expansion valve 434 to the cooler 435, and exchanges heat with the high-temperature coolant of the battery at the cooler 435 to form a low-temperature and low-pressure gas refrigerant and a low-temperature coolant, respectively; The compressed gas refrigerant flows from the refrigerant outlet of the cooler 435 to the second refrigerant tee 442, and merges with the low-temperature and low-pressure gas refrigerant flowing out of the evaporator 433 through the second refrigerant tee 442. Driven by the battery water pump 11, the low-temperature coolant flows from the water outlet of the cooler 435 through the second battery tee 32 and then flows to the battery, exchanges heat with the battery assembly 31, reduces the battery temperature and forms high-temperature coolant. The high-temperature coolant flows from the water outlet of the battery to the third port 133 of the six-way valve 13, and flows from the first port 131 of the six-way valve 13 through the first battery tee 15, the battery water pump 11, and the battery heat exchanger 438 in sequence, and then flows to the water inlet of the cooler 435, forming a battery refrigeration cycle.

[0061] like Fig.10As shown, the automobile thermal management system has the passenger compartment dehumidification and heating function. When the automobile thermal management system turns on the passenger compartment dehumidification and heating function, the first expansion valve 432, the third expansion valve 424, the second stop valve 437, and the third stop valve 425 are in an open state, the second expansion valve 434 and the first stop valve 422 are in a closed state, the third port 133 of the six-way valve 13 is connected to the first port 131 of the six-way valve 13, and the sixth port 136 of the six-way valve 13 is connected to the fourth port 134 of the six-way valve 13.

After being split through the seventh refrigerant tee 447, a part of the refrigerant flows from the second port 132 of the seventh refrigerant tee 447 through the third stop valve 425 and then flows to the second port 132 of the eighth refrigerant tee 448, and another part of the refrigerant flows from the third port 133 of the seventh refrigerant tee 447 through the third refrigerant tee 443, the third expansion valve 424, the outdoor heat exchanger 412, the ninth refrigerant tee 449 and the one-way valve 421 in sequence.

When the automobile thermal management device turns on the passenger compartment heat pump heating function, the passenger compartment heat pump heating function has a heat pump mode. In the heat pump mode, the second stop valve 437, the fourth stop valve 426 and the third expansion valve 424 are in an open state, the first stop valve 422, the fourth stop valve 426, the first expansion valve 432 and the second expansion valve 434 are in a closed state, and the sixth port 136 of the six-way valve 13 is connected to the fourth port 134 of the six-way valve 13. The refrigerant flows out from the refrigerant outlet of the compressor 431, flows through the fifth refrigerant tee 445, the second stop valve 437, the indoor condenser 436, the battery heat exchanger 438, the sixth refrigerant tee 446, the seventh refrigerant tee 447, the third refrigerant tee 443, the third expansion valve 424, the outdoor heat exchanger 412, the ninth refrigerant tee 449, the fourth stop valve 426, the tenth refrigerant tee 440, the gas-liquid separator 423, and then flows back to the refrigerant inlet of the compressor 431. The refrigerant absorbs heat at the outdoor heat exchanger and releases heat at the indoor condenser 436 to heat the passenger compartment. This function does not enable the electric heater to heat the passenger compartment, which can reduce energy consumption.

[0063] like Fig.12As shown, the passenger compartment heat pump heating function has a waste heat heating mode. When the external ambient temperature is low, the heat absorption efficiency cannot meet the heating demand, and the battery assembly 31 does not need to be heated, the waste heat heating mode can be turned on. When the waste heat heating mode is turned on, the second stop valve 437, the third stop valve 425 and the second expansion valve 434 are in an open state, the first stop valve 422, the fourth stop valve 426, the first expansion valve 432 and the third expansion valve 424 are in a closed state, the second port 132 of the six-way valve 13 is connected to the fourth port 134 of the six-way valve 13, and the sixth port 136 of the six-way valve 13 is connected to the first port 131 of the six-way valve 13.

The coolant flows out from the water outlet of the motor water pump 12, flows through the motor assembly 21, the second motor tee 22, and the radiator 411 in sequence, and then flows to the sixth port 136 of the six-way valve 13, flows out from the first port 131 of the six-way valve 13, flows through the first battery tee 15, the battery water pump 11, the battery heat exchanger 438, the cooler 435, and the second battery tee 32 in sequence, and then flows to the second port 132 of the six-way valve 13, flows out from the second port 132 of the six-way valve 13, flows through the first motor tee 16, and then flows back to the motor water pump 12. In the waste heat heating mode, the refrigerant absorbs heat from the coolant flowing out of the motor assembly 21 through the radiator 411 and the outdoor heat exchanger 412, and releases heat in the indoor condenser 436 to heat the passenger compartment.

[0064] The passenger compartment heat pump heating function has a wind heating function. When the outdoor heat exchanger 412 and the motor waste heat are unable to meet the passenger compartment heating demand, the pneumatic wind heater 439 can be used to heat the passenger compartment.

[0065] like Fig.13As shown, the automobile thermal management device has a battery forced cooling function. When the automobile thermal management device turns on the battery forced cooling function, the second expansion valve 434 and the third expansion valve 424 are in an open state, the second stop valve 437, the first stop valve 422, the fourth stop valve 426, the third stop valve 425 and the first expansion valve 432 are in a closed state, the third port 133 of the six-way valve 13 is connected to the first port 131 of the six-way valve 13, and the sixth port 136 of the six-way valve 13 is connected to the fourth port 134 of the six-way valve 13.

The motor coolant flows out from the water outlet of the motor water pump 12, flows through the motor assembly 21, the second motor tee 22, and the radiator 411 in sequence, and then flows to the sixth port 136 of the six-way valve 13, flows out from the fourth port 134 of the six-way valve 13, flows through the first motor tee 16, and then flows back to the water inlet of the motor water pump 12. The battery coolant flows out from the water outlet of the battery water pump 11, flows through the battery heat exchanger 438, the cooler 435, and the second battery tee 32 in sequence, and then flows to the third port 133 of the six-way valve 13, flows out from the first port 131 of the six-way valve 13, flows through the first battery tee 15, and then flows back to the battery water pump 11. When the temperature of the battery assembly 31 reaches the temperature point required for cooling, if it is judged that the current vehicle operating condition does not meet the conditions for using the low-temperature radiator 411 of the battery assembly 31 to cool the battery, the battery forced cooling function can be turned on. The refrigerant dissipates heat and cools down through the outdoor heat exchanger 412, and cools the battery coolant through the cooler 435, so that the refrigerant is used to cool the battery, reducing the energy consumption required for battery cooling. When the battery forced cooling function is turned on, the cooling capacity required for cooling is calculated and detected according to the battery SOC, ambient temperature, temperature of the battery assembly 31, liquid temperature of the battery coolant, charging or discharging current, and request signal of the vehicle controller VCU. By controlling the speed of the compressor 431, the opening of the second expansion valve 434, and the speed of the battery water pump 11, the battery can be cooled. When the temperature of the battery assembly 31 drops to the required shutdown temperature point, the battery forced cooling function is exited.

When the temperature of the battery assembly 31 reaches the heating demand temperature point, the battery heat pump heating function can be turned on, the refrigerant is heated through the third expansion valve 424 and the outdoor heat exchanger 412, and the battery coolant is heated through the battery heat exchanger 438, thereby realizing the battery heat pump heating function.

[0067] The automobile thermal management device can determine whether the current working condition allows the use of a heat pump to heat the battery according to the ambient temperature, the heating demand of the passenger compartment, etc. After the battery heat pump heating function is turned on, the required water temperature for battery heating is calculated according to the battery SOC, ambient temperature, the temperature of the battery assembly 31, the liquid temperature of the battery coolant, the charging or discharging current, and the vehicle controller VCU request signal to realize the battery heat pump heating function.

[0068] like Fig.15As shown, the automobile thermal management device has a low-temperature heat dissipation function for the battery. When the ambient temperature is low, the coolant temperature of the battery and the coolant temperature of the motor meet the battery cooling requirements. By switching the six-way water valve in series with the battery circuit and the electric drive circuit, the speed of the battery water pump 11 and the fan speed of the radiator 411 are controlled to achieve the battery heat dissipation function.

[0069] like Fig.16 As shown, the automobile thermal management device has a waste heat recovery battery heating function. When the automobile thermal management device turns on the waste heat recovery battery heating function, the first stop valve 422, the second stop valve 437, the third stop valve 425, the fourth stop valve 426, the first expansion valve 432, the second expansion valve 434 and the third expansion valve 424 are in a closed state, the sixth port 136 of the six-way valve 13 is connected to the first port 131 of the six-way valve 13, and the third port 133 of the six-way valve 13 is connected to the fourth port 134 of the six-way valve 13. The coolant flows out from the outlet of the motor water pump 12, flows through the motor assembly 21, the second motor tee 22, and the radiator 411 in sequence, and then flows to the sixth port 136 of the six-way valve 13, flows out from the first port 131 of the six-way valve 13, flows through the first battery tee 15, the battery water pump 11, the battery heat exchanger 438, the cooler 435, the second battery tee 32, and the battery assembly 31 in sequence, and then flows to the third port 133 of the six-way valve 13, flows out from the fourth port 134 of the six-way valve 13, flows through the first motor tee 16, and then flows back to the motor water pump 12. The heat of the electric drive system is recycled by controlling the water pump speed, the opening of the active air intake grille of the radiator 411, and switching the six-way water valve to the series battery circuit and the electric drive circuit, so that the car can recycle the heat generated by the motor assembly 21 to heat the battery assembly 31 under some working conditions to reduce the energy consumption of heating the battery.

[0070] like Fig.17As shown, the automobile thermal management device has a motor heat dissipation function. When the automobile thermal management device turns on the motor heat dissipation function, the first stop valve 422, the second stop valve 437, the third stop valve 425, the fourth stop valve 426, the first expansion valve 432, the second expansion valve 434 and the third expansion valve 424 are in a closed state, and the sixth port 136 of the six-way valve 13 is connected to the fourth port 134 of the six-way valve 13.

When the motor assembly 21 is higher than the heat dissipation requirement temperature point, it is determined that the vehicle thermal management device does not allow the waste heat heating function and the waste heat recovery battery heating function to be entered, and the motor heat dissipation function is achieved by controlling the speed of the motor water pump 12, the fan speed of the radiator 411, and switching the six-way water valve to the parallel isolation position.

By adding a circulating water valve, a kettle 14, and integrating the battery water pump 11 and the motor water pump 12, the number of parts can be effectively reduced and the device cost can be saved.
