摘要
通过分析间距对多层圆筒反射型保温结构散热损失及当量导热系数的影响 ,计算了不同条件下散热损失最小的间距分布 ,得出了最佳间距分布 ,提出了多层圆筒型反射型保温结构的优化变间距分布布置设想。与等间距结构对比 ,这种新型结构可进一步改善隔热保温效果 。
Through the analyses of the influence that spaces exert on the performance of the reflective mutiplate cylindrical structure, this paper calculates the spacing distribution, gives out the optimal spacing distribution model, according to the minimum heat flux at different emissivities, and presents a optimized variable spacing distribution ideal. Contrasted with other structures, author get such conclusion that optimized variable spacing distribution can indeed decrease heat flux greatly and improve the thermal economics effectively.
