Thermal management pipeline system for a vehicle, thermal management control method, device and vehicle

A thermal management pipeline system for a vehicle, comprising:

• a first refrigerant circulating pipeline configured for cooling or heating a driver cab of the vehicle in a thermal management mode for the driver cab;
• a second refrigerant circulating pipeline configured for cooling or heating a battery of the vehicle by using cooling capacity or heat obtained from the first refrigerant circulating pipeline in a thermal management mode for the battery, and further configured for heating the battery of the vehicle by using a refrigerant flowing into the second refrigerant circulating pipeline from a third refrigerant circulating pipeline in a thermal management mode for waste heat utilization;
• and
• the third refrigerant circulating pipeline configured for cooling an electric drive system of the vehicle in a thermal management mode for the electric drive system, wherein:
• the thermal management mode for the driver cab comprises a cooling mode for the driver cab and a heating mode for the driver cab, the first refrigerant circulating pipeline comprises:
• a first three-way valve and a second three-way valve, configured to be set to a first open state to communicate with a cooling pipeline in the first refrigerant circulating pipeline in the cooling mode for the driver cab, and further configured to be set to a second open state to communicate with a heating pipeline in the first refrigerant circulating pipeline in the heating mode for the driver cab;
• and
• wherein the cooling pipeline in the first refrigerant circulating pipeline comprises:
• a first sub-pipeline comprising a compressor, the second three-way valve, a first heat exchanger, the first three-way valve, a regenerator, a first electronic expansion valve, a third electromagnetic valve, a cold air core, and a gas-liquid separator which are connected sequentially, wherein the gas-liquid separator is further connected to the compressor;
• and
• a second sub-pipeline comprising the first three-way valve, a second electronic expansion valve, the regenerator and the compressor which are connected sequentially, wherein the first electronic expansion valve and the second electronic expansion valve are in a throttling state in the cooling mode for the driver cab, and the third electromagnetic valve is in an open state in the cooling mode for the driver cab.
