The invention provides a new energy vehicle thermal management system based on a loop heat pipe, and belongs to the technical field of new energy vehicle thermal management. The system comprises a three-electric-heat control system, a heat pump air conditioning system and a water circulation system, the three-electric-heat control system comprises three electric components and a loop heat pipe, and the loop heat pipe comprises a first evaporator, a first liquid storage device, a second evaporator, a second liquid storage device, a main condenser, a secondary condenser, a first cold plate, a second cold plate, a plurality of third cold plates and a first stop valve; the water circulation system is thermally coupled with the three-electric thermal control system and the air conditioning system through the main condenser, the secondary condenser, the first heat exchanger and the second heat exchanger, and a whole vehicle thermal management system is formed. The loop heat pipe is a passive phase-change heat transfer two-phase fluid loop, the heat transfer performance is good, extra power consumption does not need to be provided by a pump, the energy-saving effect is better, the temperature uniformity is high, only the temperature of the liquid storage device needs to be controlled, and the thermal control logic is simpler.
