The heat management system comprises a heating mode and a cooling mode, and the heating mode and the cooling mode cannot be executed simultaneously.

In the cooling mode, the three-way valve assembly 300 controls the refrigerant flowing out of the compressor 100 to flow to the outdoor condenser 101, the first flow regulating device 500 is in a throttling state, the four-way device 4 is in a throttling or cut-off state, the second connecting piece 6 communicated with the sixth cavity 123 serves as an inlet of the refrigerant of the heat exchange assembly 100, the four-way device 4 serves as an outlet of the refrigerant of the heat exchange assembly 100, and the three-way reversing device 3 is in a first working state, that is, the fifth cavity 113 is communicated with the second cavity 112 through the three-way reversing device 3. Taking the four-way device 4 in the cut-off state as an example, the compressor 200, the three-way valve assembly 300, the heat exchange assembly 100, the first flow rate adjusting device 500, and the indoor evaporator 600 in the thermal management system are sequentially communicated to form a refrigerant circuit.

Specifically, the high-temperature and high-pressure refrigerant from the compressor 200 enters the heat exchange assembly 100 through the second connection member 6, is condensed and releases heat in the outdoor condenser 101, the first one-way element 105 is in a conducting state, and the refrigerant flows into the accumulator 102 to be filtered and dried. In the liquid storage assembly 2, when the check valve 26 is in a conducting state, the refrigerant flows from the upper chamber into the lower chamber through the check valve 26, flows through the filter drying device 27 in the lower chamber, is filtered and dried, and then flows out. The refrigerant flowing out of the reservoir 102 enters the supercooling condenser 103 for further condensation and heat release through the reversing action of the three-way reversing device 3, then flows out of the heat exchange assembly 100 through the third hole 414 of the four-way device 4, enters the indoor evaporator 600 after being throttled and depressurized through the first flow regulating device 500, exchanges heat with air in the indoor evaporator 600, absorbs the heat of the air so as to reduce the temperature of the air, achieves the purpose of refrigeration, finally returns to the compressor 200, and circulates in the way. In the cooling mode, the heat exchange assembly 100 has functions of the outdoor condenser 101 and the supercooling condenser 103, and simultaneously performs functions of drying, filtering, and storing the refrigerant. After the refrigerant flows into the lower chamber of the liquid storage assembly 2, the refrigerant cannot flow out of the heat exchange assembly 100 from the first connecting piece 5 because the first connecting piece 5 is in a cut-off state, so that the possibility of the phenomenon of refrigerant backflow is reduced. When the first connecting member 5 of the heat exchange assembly 100 does not have the one-way blocking function, a device having the one-way blocking function may be connected outside the first connecting member 5 to achieve the above function.

In some other embodiments, the refrigerant flowing out of the subcooling condenser 103 may be divided into two paths, one path directly flows out of the heat exchange assembly 100 from the third hole 414 of the four-way device 4, enters the indoor evaporator 600 after being throttled and depressurized by the first flow regulating device 500, and then returns to the compressor 200; the other path of the refrigerant flows out of the heat exchange component from the fourth hole 415 of the four-way device 4, in the four-way device 4, the refrigerant passes through the coil component from the communicating hole 416 and enters the fourth hole 415 after being throttled and depressurized, then the refrigerant flows out of the heat exchange component 100 from the fourth hole 415 and enters the outdoor evaporator 700, the refrigerant exchanges heat with the air or cooling liquid loop 800 in the outdoor evaporator 700, absorbs heat of the air or cooling liquid loop 800 to cool the air or cooling liquid loop, and finally returns to the compressor 200.

In the heating mode, the three-way valve assembly 300 controls the refrigerant flowing out of the compressor 100 to flow to the indoor condenser 400, the first flow rate adjusting device 500 is in a cut-off state, the four-way device 4 is in a throttling state, the first connecting member 5 serves as an inlet of the refrigerant of the heat exchange assembly 100, the four-way device 4 serves as an outlet of the refrigerant of the heat exchange assembly 100, and the three-way reversing valve 3 is in a second working state, that is, the first chamber 111 is communicated with other elements through the three-way reversing valve 3. In the heat management system, the compressor 200, the three-way valve assembly 300, the indoor condenser 400, the heat exchange assembly 100 and the outdoor evaporator 700 are sequentially communicated to form a refrigerant loop.

Specifically, the high-temperature and high-pressure refrigerant coming out of the compressor 200 flows into the indoor condenser 400 to be condensed and release heat, so that the temperature of the indoor condenser 400 is raised, the purpose of heating is achieved, then the refrigerant enters the heat exchange assembly 100 through the first connecting piece 5, at the moment, the second one-way element 106 is in a conducting state, the refrigerant flows into the liquid accumulator 102, is filtered and dried, then is subjected to the reversing action of the three-way reversing device 3, flows into the communicating device 104 from the third channel 313 of the three-way reversing device 3, flows into the four-way device 4 from the communicating device 104, is throttled and depressurized through the four-way device 4, and then flows. In the four-way device 4, the refrigerant enters the fourth port 415 from the communication port 416, and throttling pressure reduction is realized in the process. The refrigerant flowing out of the four-way device 4 enters the outdoor evaporator 700, exchanges heat with the air or cooling liquid loop 800 in the outdoor evaporator 700, absorbs heat of the air or cooling liquid loop 800 to cool the air or cooling liquid loop, and finally returns to the compressor 200, and the cycle is repeated. In the heating mode, the outdoor condenser 101 and the supercooling condenser 102 of the heat exchange assembly 100 do not participate in heat exchange, and the lower chamber of the liquid storage assembly 2 performs functions of drying, filtering and storing the refrigerant, after the refrigerant flows into the lower chamber, because the check valve 26 is in a cut-off state, the refrigerant cannot flow into the upper chamber from the check valve 26 and then enters the fifth chamber 113, so that the possibility of the refrigerant backflow phenomenon is reduced.

In some other embodiments, the refrigerant flowing out of the communicating vessel 104 may be divided into two paths, one path directly flows out of the heat exchange assembly from the third hole 414 of the four-way device 4, enters the indoor evaporator 600 after being throttled and depressurized by the first flow regulating device 500, and then returns to the compressor 200, the indoor evaporator 600 is disposed on the windward side of the indoor condenser 400, and the air is firstly reduced in humidity by the indoor evaporator 600, then is heated by the indoor condenser 400 and then is blown into the passenger compartment, so as to achieve the purposes of heating and dehumidifying; the other path of the refrigerant flows out of the heat exchange assembly 100 from the fourth hole 415 of the four-way device 4, flows into the fourth hole 415 after throttling and pressure reduction from the communicating hole 416 in the four-way device 4, then flows out of the heat exchange assembly 100 from the fourth hole 415, enters the outdoor evaporator 700, and then returns to the compressor 200, and can exchange heat with the cooling liquid loop 800 at the outdoor evaporator 700, so that the temperature reduction of the battery assembly or the motor assembly is realized.
