摘　　要：分析了槽形抛物聚光集热器中管簇结构腔体式吸收器的热物理特性，依据其热阻网络、太阳能一般性控制方程对热损和所受边界条件的影响作了数值分析。In this paper,the, thermal performance of a novel solar cavity receiver with a bundle of tubes as an absorber is analysed, Based on the heat resistance network,the general control equations of solar energy, the influence of environmental conditions (solar direct irradiance, ambient temperature, and wind velocity) on the heat loss is numerically calculated.
