Abstract

The utility model provides a vehicle and a thermal management system thereof. A refrigerant loop of the vehicle heat management system comprises a compressor, a first heat exchanger, a liquid storage dryer, a first internal heat exchanger, a fourth heat exchanger, a second heat exchanger, a second double-fluid heat exchanger, a first double-fluid heat exchanger, a second internal heat exchanger, a third heat exchanger and a fifth heat exchanger. The flow direction of refrigerants in the first heat exchanger is reversible, the first heat exchanger can serve as an evaporator or a condenser, and the refrigerants in the high-pressure side heat exchange channels and the low-pressure side heat exchange channels in the first internal heat exchanger and the second internal heat exchanger can conduct heat exchange. The direct-type double-steam heat pump air-conditioning system can be formed, the structure of the direct-type double-steam heat pump air-conditioning system is simple, meanwhile, on the basis of a heat pump mode, various working modes such as single refrigeration, double refrigeration, waste heat recovery, battery heating and dehumidification can be achieved, and application and popularization of the vehicle-mounted heat pump system are facilitated.
