Description

Technical Field

[0001] This invention relates to the field of thermal management technology for new energy vehicles, specifically a super-integrated thermal management system for R290 vehicles used in new energy vehicles. Background Technology

[0002] Today's society places increasingly higher demands on energy conservation and emission reduction. Currently, the refrigerant commonly used in automotive air conditioning is R134a, which has a GWP (Global Warming Potential) of 1300 and is a greenhouse gas whose use will be gradually restricted. Furthermore, when used as a medium in heat pump air conditioning systems of new energy vehicles, R134a exhibits poor low-temperature performance and limited applicability. Its efficiency is low and the system is unstable in environments below -10°C, often requiring a PTC (Potentially Transmitted Temperature) heater, resulting in high energy consumption at low temperatures and reduced driving range in cold environments. Therefore, it is necessary to find a refrigerant with a low GWP and high thermal properties to replace it.

[0003] R290 is an environmentally friendly natural working fluid with a GWP of 3 and excellent thermal properties, but it has high flammability, classifying it as a Class A3 flammable medium, posing a safety hazard during system use. Therefore, it is necessary to integrate the R290 refrigerant system. Current research shows high refrigerant-side integration but low water-side integration, and existing front-end low-temperature radiators cannot meet the heat dissipation requirements under high-temperature cooling conditions. Furthermore, the vehicle's electric drive cooling module and air conditioning cooling module require a front-to-back arrangement; placing one in the front will affect the cooling capacity of the other.

The pressurized gaseous refrigerant is then transported to the water-cooled condenser for condensation. The condensed refrigerant is further condensed through the regenerator to ensure that the refrigerant entering the storage tank is pure liquid refrigerant. After passing through electronic expansion valve 1 and undergoing throttling and pressure reduction, it enters the battery cooler, thus completing the refrigerant circuit cycle; the coolant after heat exchange with the refrigerant in the battery cooler enters through inlet 7 of the nine-way valve and exits through the nine-way valve. The air flows out through port five, reaching the indoor cooler and cooling the air in the passenger compartment. It is then pumped back to the battery cooler by the cooling water pump. At the same time, the blower sends the cold air from the indoor cooler to the passenger compartment, further cooling the passenger compartment. The coolant that has exchanged heat with the refrigerant in the water-cooled condenser enters through port eight of the nine-way valve through the liquid heater, exits through port two of the nine-way valve, reaches low-temperature radiator two, then passes through low-temperature radiator one, and dissipates heat to the outside through the electric fan. It then flows through three-way water pipe one, stop valve two, three-way water pipe two, stop valve one, three-way water pipe four, and is pumped back to the water-cooled condenser by the controlled hot water pump.

It enters the indoor heater through the proportional three-way valve one and heats the air in the passenger compartment. Then, after passing through the three-way water pipe five and the three-way water pipe four, it is transported back to the water-cooled condenser by the hot water pump; at the same time, the blower sends the hot air from the indoor heater to the passenger compartment, thereby heating the passenger compartment; the coolant in the battery cooler, after heat exchange with the refrigerant, enters from the inlet seven of the nine-way valve, exits from the outlet two of the nine-way valve, enters the low-temperature radiator two through the three-way water pipe seven, then passes through the low-temperature radiator one, and absorbs heat from the outside through the electric fan.

Then, it is transported back to the battery cooler from the outlet six of the nine-way valve through the four-way water pipe by the chilled water pump.

[0035] d) Dual-source heat pump mode: The electric compressor starts, completing the refrigerant loop circulation, while the hot water pump and chilled water pump start simultaneously; the coolant, after heat exchange with the refrigerant in the water-cooled condenser, enters inlet eight of the nine-way valve, exits from outlet nine of the nine-way valve, and enters the indoor heater through proportional three-way valve one, heating the air in the passenger compartment. Then, after passing through three-way water pipe five and three-way water pipe four, it is pumped back to the water-cooled condenser by the hot water pump; simultaneously, the blower sends the hot air from the indoor heater to the passenger compartment, thus heating the passenger compartment; battery cooling...

[0037] f) Hot gas bypass heat pump: The electric compressor starts and pressurizes the low-temperature, low-pressure refrigerant. Part of the pressurized gaseous refrigerant is sent to the water-cooled condenser for condensation. The condensed refrigerant is further condensed through the regenerator to ensure that the refrigerant entering the liquid tank is pure liquid refrigerant. After passing through the electronic expansion valve 2, it bypasses the battery cooler to reduce heat loss. After being throttled and depressurized by the electronic expansion valve, it merges with another part of the refrigerant after being throttled by the electronic expansion valve 3 and enters the regenerator before returning to the compressor. At the same time, the hot water pump starts. The coolant in the water-cooled condenser, after heat exchange with the refrigerant, enters the inlet 8 of the nine-way valve and exits through the outlet 9 of the nine-way valve.

It enters the water-to-water heat exchanger 1 through the proportional three-way valve 1 and is heated in the battery-side water circuit. Then, after passing through the three-way water pipes 5 and 4, it is transported back to the water-cooled condenser by the hot water pump; the battery water pump transports the water from the battery circuit to the water-to-water heat exchanger 2, where it exchanges heat with the coolant on the cooling side and absorbs heat before entering the power battery to heat the battery; the coolant after heat exchange with the refrigerant in the battery cooler enters from the inlet 7 of the nine-way valve, exits from the outlet 4 of the nine-way valve, and is transported into the electric drive assembly by the electric drive water pump after passing through the three-way water pipe 3.

Then, it is transported back to the battery cooler from the outlet 6 of the nine-way valve through the four-way water pipe by the cooling water pump.

[0041] The operating modes of the electric drive circuit cooling system are as follows:

[0042] a) The electric drive water pump starts and delivers coolant to the electric drive assembly for heat absorption. Then it enters the inlet of the nine-way valve and exits through the outlet of the nine-way valve. It then enters the low-temperature radiator 2 through the three-way water pipe 7. After entering the low-temperature radiator 1 and dissipating heat to the outside through the electric fan, it passes through the three-way water pipe 1, the shut-off valve 2, the three-way water pipe 2, and the three-way water pipe 3 before being delivered to the electric drive assembly by the electric drive water pump.

This invention optimizes the refrigerant circuit, employing only a single water-cooled condenser and battery cooler, thereby minimizing refrigerant charge and ensuring system safety. Furthermore, this invention adds a regenerator after the system's water-to-water heat exchanger, ensuring a subcooled section of the system and optimizing the compressor's suction superheat, thus protecting the compressor's lifespan.

[0045] 2. This invention integrates the water circuit using a nine-way valve, reducing the length of the water circuit pipes used, increasing the usable space in the engine compartment, and saving water circuit pipe costs. Furthermore, the integrated module is located far from the passenger compartment, further ensuring safety. In addition, this invention connects the electric drive cooling and air conditioning cooling in parallel, using two front-end low-temperature radiators connected in parallel, which improves the heat dissipation capacity and can meet the cooling needs of both the electric drive and air conditioning.
