讨论了一种新型的管簇结构腔体式吸收器，基于网络法建立了确定各种热流的控制方程及总热阻并给出集热器及各主要部件的效率定义式，最后对热性能进行了详细的数值分析。
A new type of tube - type absorber with tube - tube structure is discussed. Based on the network method, the governing equation and the total thermal resistance for determining various heat fluxes are established. The efficiency of the collector and the main components are defined. Finally, the thermal performance A detailed numerical analysis.
