The invention relates to a charging pile thermal control system based on a pulsating heat pipe and a control method thereof. A charging pile thermal control system based on a pulsating heat pipe comprises a charging pile shell, a power module and a fan, and the power module is provided with a heat dissipation assembly and a heat compensation assembly; the pulsating heat pipe for heat dissipation is bent into a U-shaped structure, sleeved with a phase-change material sleeve plate and in surface contact with the power module, the middle of the pulsating heat pipe is an evaporation end, and two wings of the pulsating heat pipe are condensation ends. The pulsating heat pipe for heat compensation is bent into a U-shaped structure, sleeved with the phase change material sleeve plate and in surface contact with the power module, the middle portion of the pulsating heat pipe is a condensation end, the two wing portions of the pulsating heat pipe are evaporation ends, and electric heaters are arranged at the evaporation ends. A heat dissipation mode of coupling the micro-channel flat plate pulsating heat pipe and the phase-change material is adopted, the pulsating heat pipe is free of a core and a pump and does not need gravity assistance, the contact area is increased in a flat plate mode, the upper limit of heat dissipation power is improved, the temperature uniformity is improved by adding the phase-change material, energy is saved, and the stability and continuity of a heat dissipation system are improved.
