[0069] The whole vehicle thermal management system provided in the application can realize six working modes by controlling the throttling valves and expansion valves in the system, so as to meet the temperature requirements of the passenger compartment, the battery and the cup holder.

[0070] The first working mode (passenger compartment refrigeration, battery refrigeration, cup holder refrigeration): the first throttling valve, the fifth throttling valve, the sixth throttling valve, the seventh throttling valve, the eleventh throttling valve, the twelfth throttling valve, the first expansion valve, the third expansion valve and the fourth expansion valve are opened, and the second throttling valve, the third throttling valve, the fourth throttling valve, the eighth throttling valve, the ninth throttling valve, the tenth throttling valve, the thirteenth throttling valve and the second expansion valve are closed. After the high-temperature and high-pressure gaseous refrigerant is discharged from the air conditioner compressor, it passes through the first pipeline, the third pipeline and the second pipeline in turn and enters the outdoor condenser. After the high-temperature and high-pressure gaseous refrigerant passes through the outdoor condenser, it forms low-temperature and high-pressure supercooled liquid refrigerant. The refrigerant discharged from the outdoor condenser enters the ninth pipeline through the eleventh pipeline. The first part of the refrigerant enters the evaporator through the ninth pipeline to refrigerate the passenger compartment, and then enters the gas-liquid separator through the fourteenth pipeline and the thirteenth pipeline in turn. The second part of the refrigerant enters the battery temperature control device through the ninth pipeline and the eighth pipeline to refrigerate the battery, and then enters the gas-liquid separator through the seventh pipeline, the sixteenth pipeline and the thirteenth pipeline in turn. The third part of the refrigerant enters the cold and hot cup holder device through the ninth pipeline, the tenth pipeline and the sixth pipeline in turn to refrigerate the cold and hot cup holder device, and then enters the gas-liquid separator through the fifth pipeline, the fifteenth pipeline and the thirteenth pipeline in turn. The refrigerant entering the gas-liquid separator is in a gas-liquid mixed state. After being separated by the gas-liquid separator, the gaseous refrigerant enters the air conditioner compressor to form high-temperature and high-pressure gaseous refrigerant, thereby realizing circulation.

The refrigerant entering the gas-liquid separator is in a gas-liquid mixed state, and after separation by the gas-liquid separator, the gaseous refrigerant enters the air conditioning compressor to form high-temperature and high-pressure gaseous refrigerant, thereby realizing circulation.

It then passes through the seventh, sixteenth, and thirteenth pipelines before entering the gas-liquid separator. The other portion passes through the twelfth, ninth, tenth, and sixth pipelines before entering the hot / cold cup holder device to cool it. It then passes through the fifth, fifteenth, and thirteenth pipelines before entering the gas-liquid separator. The refrigerant entering the gas-liquid separator is a gas-liquid mixture.
