摘　　要：太阳能的能流密度较低,不易利用,而太阳能聚光集热器能够将分散的太阳光聚集到一个较小的面积上,增强太阳光的能流密度,改善光热转换的效果,均匀聚光器是近年来提出的一种能实现较为均匀热流分布的聚光器。针对一种均匀聚光器,本文首先建立均匀聚光器模型,采用蒙特卡洛光线追踪法模拟光源特性;而后以获得的光源特性作为输入光源,通过TracePro软件模拟得到吸热管表面热流密度分布。研究结果表明,吸热管上部分区域的实际热流分布与目标热流分布存在差异。需要对聚光器上的部分区域进行优化,才能使吸热管呈现目标热流分布。Solar energy has a low flux density,so it is hard to use.The solar concentrator collects the sunlight into a small area,which can enhance the sunlight energy flow density and improve the effect of photothermal conversion.The surface uniform concentrator is a kind of concentrator which can acquire uniform heat flow distribution.In the present study,the model of surface uniform concentrator is established,and the characteristics of light source are simulated through the Monte Carlo ray tracing method.The heat flux distribution on the surface of the absorber is simulated by using TracePro software.The results show that the actual heat flow distribution is different from the target heat flow distribution in some areas of the absorber.Some areas on the absorber need to be optimized so that target heat flow distribution can be seen on the absorber.
