It can realize more than 20 functional modes. The following specifically introduces the working process of two typical functional modes of the thermal management integrated module of this embodiment.

[0082] Working mode 1: Passenger compartment cooling, battery pack cooling and motor and electronic control module heat dissipation

[0083] In this mode, the refrigerant integrated module part 1 and the water-cooled integrated module part 2 work at the same time. The refrigerant working cycle path of the refrigerant integrated module is: the refrigerant is discharged from the electric compressor and enters the refrigerant inlet hole 131 of the water-cooled condenser in the refrigerant integrated module. The high-temperature refrigerant flows through the water-cooled condenser 13 to perform heat exchange with the coolant flowing through the water-cooled condenser. Then the refrigerant enters the liquid storage dryer 16 through the first refrigerant flow channel 121. After leaving the liquid storage dryer, it enters the electronic expansion valve 15 through the second refrigerant flow channel 122. After entering the electronic expansion valve, the refrigerant passes through the 2 refrigerant inlet holes of the electronic expansion valve. The first refrigerant flows out from the first outlet 161 of the electronic expansion valve through the third refrigerant flow channel 123 into the water-cooled evaporator 14, and the low-temperature refrigerant flows through the water-cooled evaporator to exchange heat with the coolant flowing through the water-cooled evaporator. Then the refrigerant returns to the compressor through the refrigerant outlet hole 134 of the water-cooled evaporator. The second refrigerant enters the passenger compartment air-conditioning box through the second outlet 153 of the electronic expansion valve. After heat exchange in the passenger compartment air-conditioning box, the low-temperature refrigerant returns to the electric compressor through the passenger compartment air-conditioning box outlet, forming a complete refrigerant circulation loop to achieve the function of cooling the passenger compartment.

[0086] Working mode 2: passenger compartment heating, battery pack heating and motor and electronic control module heat dissipation (heat pump)

[0087] In this mode, the refrigerant integrated module part 1 and the water-cooled integrated module part 2 work simultaneously. The refrigerant working circulation path of the refrigerant integrated module part 1 is: the refrigerant is discharged from the electric compressor and enters the refrigerant inlet hole 131 of the water-cooled condenser in the refrigerant integrated module. The high-temperature refrigerant flows through the water-cooled condenser to exchange heat with the coolant flowing through the water-cooled condenser, and then enters the liquid storage dryer 16 through the first refrigerant flow channel 121. After exiting the liquid storage dryer, it enters the electronic expansion valve 15 through the second refrigerant flow channel 122. After entering the electronic expansion valve, the refrigerant enters the water-cooled evaporator through the first outlet 152 of the electronic expansion valve through the third refrigerant flow channel 133. The low-temperature refrigerant flows through the water-cooled evaporator to exchange heat with the coolant flowing through the water-cooled evaporator, and then the refrigerant returns to the compressor through the refrigerant outlet 142 of the water-cooled evaporator, forming a complete refrigerant circulation loop.

[0088] The first electronic water pump 25, the second electronic water pump 26 and the third electronic water pump 27 in the water-cooled integrated module part 2 are started, the first five-way valve 22 is switched to connect port No. 2 2202 with port No. 5 2205, and connect port No. 4 2204 with port No. 1 2201, the second five-way valve 23 is switched to connect port No. 2 2302 with port No. 3 2303, and connect port No. 4 2304 with port No. 5 2305, the third five-way valve 24 is switched to connect port No. 2 2402 with port No. 1 2401, and connect port No. 4 2404 with port No. 5 2405, the three-way water valve 28 is in the middle state, and the opening of the two outlets is adjusted according to the water temperature. Specifically, the coolant flows out through the first electronic water pump 25, enters the water heater through the thirteenth water channel 2013, flows out from the water heater and enters the heater of the passenger compartment air conditioning box, and then flows out into the inlet 281 of the three-way water valve. The three-way water valve is in the middle state, and the opening of the water valve is adjusted by the problem of the coolant. After flowing out through the first outlet 282 of the three-way water valve, the coolant flows out through the fourteenth water channel 2014 and enters the water channel inlet 133 of the water-cooled condenser in the refrigerant integrated module. The coolant flowing through the water-cooled condenser exchanges heat with the high-temperature refrigerant in the water-cooled condenser, and the coolant is heated. The heated coolant flows out from the water outlet 134 of the water-cooled condenser and enters the No. 2 port 2302 of the second five-way valve through the seventh water channel 2007, and flows out from the No. 3 port 2303 of the second five-way valve through the first water channel 2001 and enters the first electronic water pump 25, forming a coolant circulation loop. In this coolant circulation loop, the coolant heated by the water-cooled condenser enters the heater of the passenger compartment air-conditioning box, and is circulated through the blower of the air-conditioning box. The circulating air in the vehicle exchanges heat with the high-temperature coolant of the air-conditioning box heater, thereby achieving the function of heating the air in the passenger compartment.

[0089] Another channel of heated coolant flows out through the second outlet 283 of the three-way water valve, enters the second electronic water pump 26 through the sixth water channel 2006, and then enters the battery pack through the fifteenth water channel 2015. The heated coolant flows through the battery pack to exchange heat with the battery pack, thereby achieving the function of heating the battery pack. After flowing out of the battery pack, the coolant enters the No. 4 port 2204 of the first five-way valve through the fourth water channel 2004, and then flows out from the No. 1 port 2201 of the first five-way valve into the first water channel 2001. After entering the first water channel, the coolant merges with the previous coolant and enters the first electronic water pump 25 through the first water channel 2001, forming a complete circulating water circuit. This complete circulating water circuit realizes the functions of heating the passenger compartment and the battery pack.

[0090] At the same time, the third electronic water pump 27 starts to work, and the coolant flows out of the third electronic water pump 27, enters the No. 2 port 2202 of the first five-way valve through the second water channel 2002, and then flows out through the No. 5 port 2205 of the first five-way valve and enters the water-cooled evaporator 14 in the refrigerant integrated module through the fifth water channel 2005. The coolant flowing through the water-cooled evaporator exchanges heat with the low-temperature refrigerant in the water-cooled evaporator. The cooled coolant flows out from the water outlet 144 of the water-cooled evaporator, enters the No. 4 port 2304 of the second five-way valve through the eighth water channel 2008, and then flows out through the No. 5 port 2205 of the second five-way valve. The coolant flows out from port 5 2305 of the five-way valve, enters port 2402 of the third five-way valve through the ninth water channel 2009, flows out from port 1 2401 of the third five-way valve, and enters the water inlet of the motor and electronic control module through the tenth water channel 2010. The coolant flows through the motor and electronic control module and returns to the third electronic water pump 27 from the outlet of the motor and electronic control module through the twelfth water channel 2012, forming a coolant circulation loop. During this circulation loop, the cooled coolant flows through the motor and electronic control module, achieving the purpose of cooling the motor and electronic control module, thereby realizing the heat dissipation function of the motor and electronic control module.
