  • 摘要: 基于均匀设计方法设计了6个太阳能蓄热装置,将石蜡RT110作为相变材料封装于带内翅片的圆柱管蓄热单元内,建立蓄热单元模型并对其蓄热特性进行研究.结果表明:蓄热单元结构及尺寸对相变材料的蓄热速率有较大影响,并且较小的蓄热单元内径、较多的翅片和较大的翅片高度可以显著增加蓄热量;蓄热单元各因素的二阶交互作用对蓄热单元蓄热能力的影响也很大,其中翅片厚度与翅片个数、圆柱内径协同影响蓄热单元的蓄热能力.
    Abstract: Based on the uniform design method, six solar heat storage devices were disigned, the phase change material of paraffin RT110 was encapsulated in the heat storage unit of cylindrical tube with inner finned, and the heat storage unit model was established and its heat storage properties were investigated. Results showed that the structure and size of the heat storage unit had a great influence on heat storage rate of phase change materials. The smaller the inner diameter, the more the fins and the longer the fin width, the capacity of heat storage was greater. The capacity of heat storage was influenced greatly by the second-order interaction of various factors. The fin width, the fin number and the inside diameter of cylindricity collaboratively affected the capacity of heat storage unit.
