【Abstract】 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.更多还原
