The invention discloses a whole vehicle thermal management system based on a fuel heater. The system comprises a refrigerant loop, a battery cooling liquid loop and an air conditioner cooling liquid loop which are connected through a heat exchanger. The battery cooling liquid loop comprises a power battery and a battery cooling water pump, and the power battery, the battery cooling water pump and the heat exchanger are sequentially connected. The air conditioner cooling liquid loop comprises an air conditioner heating water pump, a fuel oil heater, an electronic three-way valve and an air conditioner heater which are sequentially connected, the other port of the electronic three-way valve is connected with the heat exchanger, and the heat exchanger is further connected with the air conditioner heating water pump to form a loop so that heat exchange is achieved between the air conditioner cooling liquid loop and the battery cooling liquid loop. Aiming at a low environment temperature (less than-20 DEG C), the heating effect of the whole vehicle is obviously improved, the thermal comfort in cold seasons is improved, the energy of a power battery is not consumed, and the endurance mileage is favorably increased; in addition, the heating effect of the battery pack is obviously improved, and the energy of the power battery is not consumed.
