| 摘 要： | 介绍了电热固体蓄热装置的蓄热原理和蓄热用材料,对加热过程和放热过程进行了传热分析。在加热阶段,电能转换成热能,热能以辐射和导热方式传递给蓄能介质;在放热阶段,空气与蓄热介质表面进行对流换热,蓄热介质内部的换热仍为导热。

| Abstract: | The heat storage principle and material of electric heat solid heat storage device is introduced, and heat transfer analysis is made on the heating and discharging. Electric energy is converted into thermal energy and thermal energy is transferred to media of stored energy by the methods of radiant and conduction during heating. Convection transfer is conducted between air and the media surface and heat transfer inside of the media is still conduction. |
