Abstract: The heat storage performance of heat storage device is directly affected by its’ thermal insulation structure. The application of Al-Si alloy in phase change energy storage is limited by the heat loss caused by its high working temperature. Aiming at the thermal insulation problem of high temperature phase change heat storage device, four different insulation structures such as glass wool, aerogel, composite aerogel and vacuum sandwich composite aerogel, used in the Aluminum-silicon alloy phase change heat storage device with the working temperature as high as 600 ℃, are put forward. A series of heat storage, thermal insulation and thermal release experiments are carried out, the thermal insulation performance compared including the shell temperature, the dissipated power and the thermal efficiency, and the influence of thermal insulation materials and vacuum interlayer on thermal insulation performance analyzed and studied. The results show that when the heat storage temperature is 600 ℃, the shell temperatures of glass wool, aerogel, composite aerogel and vacuum sandwich composite aerogel are, respectively, 91 ℃, 54 ℃, 51 ℃ and 41 ℃, the dissipated power is 589 W, 364 W, 325 W and 151 W, and the thermal efficiency is 0.64, 0.85, 0.88 and 0.94, respectively. The thermal insulation performance of vacuum sandwich composite aerogel is the best.

Key words: Al-Si alloy, phase change heat storage, thermal insulation structure, dissipated power, store thermal efficiency
