Phase-change material coupling vapor chamber and thermal management system of copper high-thermal-conductivity material

The invention discloses a thermal management system for coupling a phase change material with a vapor chamber and a copper high-thermal-conductivity material, and the thermal management system comprises a subsystem which comprises a first fin, the vapor chamber, a second fin, a fin tube, a battery cell and the phase change material; a plurality of second fins wrap the outer wall of the finned tube in a surrounding manner, and the adjacent second fins are parallel to each other and are arranged at equal intervals; a plurality of battery cells are correspondingly mounted in the finned tubes to form a battery pack; the centers of the battery core, the finned tube and the second fins are positioned on the same axis; the phase change material is in a honeycomb shape and is composed of a plurality of hexagonal cylinders which are tightly arranged, each hexagonal cylinder is provided with a vertical through groove, and the finned tubes are arranged in the vertical through grooves; honeycomb-shaped vapor chambers are
