The invention discloses a thermal management system for coupling a phase change material with a heat conduction copper pipe. The thermal management system mainly comprises a first pipe body, a second pipe body, a battery cell, a first phase change material, a second phase change material, a spiral baffle plate and a spiral radiator. When the battery works, a large amount of heat is generated, heat dissipation is needed when the temperature rises, the heat generated by the battery cell is transmitted to the first phase-change material and the second phase-change material, the two phase-change materials absorb the heat and then transmit the heat to the second pipe body, a part of the heat is taken away by gas in an air channel formed by the spiral baffle plate, and the heat dissipation efficiency is improved. And the other part of the heat is transmitted to the spiral baffle plate through the second pipe body and finally transmitted to the first pipe body and the tooth-shaped spiral fins on the periphery, so th
