The invention belongs to the technical field of vehicle thermal management, and particularly relates to a thermal management system of a pure electric vehicle. Comprising a compressor, a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve, a first electronic expansion valve, a second electronic expansion valve, a third large-diameter electronic expansion valve, a condenser, an inner condenser, an evaporator, an air heating PTC, a gas-liquid separator, a water-cooled condenser, a Chiller, a first water pump, a second water pump, a third water pump, a nine-way valve, a radiator, a water heating PTC, a first expansion kettle and a second expansion kettle. The thermal management system of the pure electric vehicle is provided with a refrigerant loop and a refrigerant fluid loop. By controlling the electromagnetic valves and the expansion valves, 27 different refrigerant circulation loops can be formed through combination; by controlling the gears of the nine-way valve, six different refrigerant fluid circulation loops can be formed; more than thirty working modes can be realized, various thermal management requirements of an automobile are met, the driving experience of a user is improved, multi-area heat can be comprehensively recycled, the system performance is improved, and the system energy consumption is reduced.
