The device takes the flat micro heat pipe array as the core heat transfer element and the lauric acid as the phase change heat storage material. An experimental test system was set up to test the heat and storage of the phase-change heat accumulator under different air flow rates and inlet temperatures. The average temperature performance of the flat heat pipe array during storage and storage, the temperature change inside the heat accumulator, And heat storage power were experimentally studied and analyzed. The results show that the micro-heat pipe array module shows good average temperature during the process of heat storage and exotherm, and the work is efficient and stable. The actual heat storage and storage performance of the phase-change heat storage device is excellent, and the average heat storage and exothermic power are 418 W and 353 W.
