【摘要】 利用ANSYS软件分析了外界温度波动对环形结构密闭壳体储热装置内部温度的影响。模拟结果表明，隔热层能阻碍热量的传递，降低装置内的温度变化速率。在外界温度波动过程中，装置内外温度始终存在一定的温度差。装置内外表面采用玻璃纤维隔热层，装置内温度变化速率明显降低且其温差远远小于外界温差。更多还原

【Abstract】 ANSYS software is used to analyze the impact of external temperature fluctuations on the internal temperature of a closed shell heat storage device with an annular structure. The simulation results indicate that the insulation layer can hinder the transfer of heat and slow down the rate of temperature change inside the device. During the process of external temperature fluctuations, there is always a certain temperature difference between the inside and outside of the device.The glass fiber insulation layer is applied on internal and external surfaces of the device. The fluctuation amplitude of the internal temperature of the device is much smaller than that of the external temperature.更多还原
