摘要

针对传统复合抛物面聚光器（CPC）高宽比较大、接收角较小、聚光能流分布不均匀等问题

通过建立几何型线数学模型

设计复合双曲面聚光器（CHC）

获得不同几何聚光比下聚光器的高宽比以及接收半角。运用蒙特卡洛光线追踪方法

对比分析CPC和CHC的光学效率

辐照非均匀度。结果表明

不同聚光比下CHC的高宽比总是小于CPC

接收半角总是大于CPC。以聚光比分别为2和4为例

CHC的高宽比分别为1.5和5.6

均小于CPC的2.6和7.5;CHC的接收半角分别为53.14°和28°

均大于CPC的30°和14.1°。对比两者在不同入射角条件下的光学效率

CPC在接收角范围内的光学效率更高

但CHC相较于CPC持续聚光能力更强。当CHC聚光比分别为2和4时

需分别在纵向长度上增加约20%和30%的反射面积来弥补在CPC接收半角内所损失的光学效率

而在CPC接收半角之外

CHC所具有的宽接收半角可使两种聚光器聚光能力相近。此外

在不同入射角条件下

CHC最大辐照非均匀度分别为0.59和0.58

均小于CPC的6.31和12.51

接收面能流分布更加均匀。以上结果表明

相较于传统CPC

CHC高宽比较小、接收角较大、聚光能流分布更均匀

在应用于免跟踪低倍聚光光伏光热系统上具有更好的潜力。

Abstract

To address the issues of high aspect ratio

small acceptance angle and non-uniform irradiance distribution in traditional compound parabolic concentrators （CPCs）

a compound hyperbolic concentrator （CHC） was designed by establishing a mathematical model of the geometric profile. The half acceptance angles and aspect ratios of the concentrators were obtained under different geometric concentration ratios. By applying the Monte Carlo ray tracing method

the optical efficiency and irradiance non-uniformity of CPC and CHC were analyzed. The results indicated that under different concentration ratios

the aspect ratio of CHC was always lower than that of CPC

and the half acceptance angle of CHC was always larger than that of CPC. When the concentration ratios were 2 and 4

the aspect ratios of CHC were 1.5 and 5.6 respectively

which were lower than those of CPC at 2.6 and 7.5. The half acceptance angles of CHC were 53.14° and 28° respectively

which were largr than those of CPC at 30° and 14.1°. The optical efficiency of CPC within the acceptance angle range was higher than that of CHC

but CHC possessed a stronger ability for continuous concentration than CPC. When the concentration ratios were 2 and 4

respectively

it was necessary to increase the reflective area of CHC by approximately 20% and 30% along the longitudinal direction to compensate for its lower optical efficiency within the CPC half acceptance angles. However

outside the CPC half acceptance angles

the wider half acceptance angles allowed the CHC to achieve similar concentrating performance to CPC. Additionally

under different incident angles

the maximum irradiance non-uniformity of CHC （0.59 and 0.58） was much lower than that of CPC （6.31 and 12.51）

suggesting a more uniform irradiance distribution on the receiving surface. On account of lower aspect ratio

wider acceptance angle and more uniform irradiance

CHC had better potential than CPC in the application of non-tracking low concentrating photovoltaic/thermal systems.
