摘　　要：文章基于SolidWorks软件建立了圆柱孔簇腔式吸热器的物理、光学模型,然后利用Optisworks软件对该吸热器内壁的能流分布情况进行仿真,最后根据模拟结果研究了圆柱孔簇的结构参数对该吸热器的光学效率及其内壁能流分布情况的影响。分析结果表明:圆柱孔长度是吸热器内壁能流峰值的主要决定因素,圆柱孔长度对吸热器的光学效率无显著影响;吸热器内壁能流随着圆柱孔间距的增大而逐渐减小;吸热器中心圆柱孔内壁能流随着圆柱孔半径的增大而增大,吸热器第二层圆柱孔内壁能流随着圆柱孔半径的增大而减小;吸热器的光学效率随着圆柱孔间距的增大而减小,随着圆柱孔半径的增大而增大。The optical and physical model of cylindrical cluster cavity receiver were established based on SolidWorks software. Using Optisworks software to carry out the internal wall flux distribution simulation of the receiver. The influence of the parameters on the flux distribution and optical efficiency of the inner wall of the receiver was analyzed. The results show that the cylindrical hole length determines the flux peak value of the inner wall of the receiver, while it has no significant influence on the optical efficiency. The flux value of the receiver inner wall decreased with the increase of the space of cylindrical hole. The flux value of the wall in the central cylindrical hole gradually increased with the radius of the cylinder, while the flux value of the wall in the second ring decreases as the radius of the cylinder increases. The optical efficiency of the receiver is gradually decreased with the increase of the space of cylindrical hole, while the optical efficiency increases gradually with the increase of the radius of the cylindrical hole.
