摘　　要：分析了槽形抛物镜聚光集热器中管簇结构腔体式吸收器的热物理特征，依据其热阻网络、太阳能一般性控制方程和计算框图对其热效率在自动跟踪条件下所受边界条件（太阳直射辐射强度、室外空气温度、室外风速、工作介质流速）影响作了数值分析。n this paper, the thermal characteristics of a novel solar cavity receiver using a bundle of tubes as an absorber is analysed. Based on the heat resistance network,the general control equations of solar energy and calculation fram figure, the influence of environment condition (solar straight radiation intensity, outside air temperature,out side wind velocity, actuating medium flowing velocity) on the heat efficiency is numerically analysed.
