Thermal management structure

A heat management structure comprises a heat transfer unit, a heat dissipation structure, a phase change heat storage unit and a heat insulation shell. The heat transfer unit is connected with the heat dissipation structure, and the phase change heat storage unit is arranged on the heat dissipation structure. The heat dissipation structure and the heat insulation shell form a sealed cavity, and the phase change heat storage unit is located in the sealed cavity. The heat transfer unit is connected with a heat source. The graphene phase change material, the internal aluminum heat conduction sheet and the paraffin phase change material embedded in the aluminum heat conduction sheet are utilized to form a complete heat conduction and heat storage system, and heat energy at the hot end of the back face of the semiconductor refrigeration sheet is rapidly transferred to other components in the heat management system built by the semiconductor refrigeration sheet heat management system. Therefore, the good cold compr
