摘要
针对太阳能槽式系统反射镜玻璃厚度对聚光特性的影响进行了理论、模拟和实验研究。研究结果表明,平行光下反射镜玻璃越厚,入射光线距光轴距离越远,ΔX、ΔY越大。对焦距为1200mm,反射镜玻璃折射率为1.6的槽式系统进行了理论计算,玻璃厚度为1 mm的反射镜,当距光轴距离为200 mm和2000 mm时,ΔX为0.03mm和1.69mm,ΔY为0.19mm和0.31mm;当距光轴距离仍为2000mm时,玻璃厚度为5mm的反射镜,ΔX为8.41mm,ΔY为1.55mm。通过TracePro模拟以及实际实验测量,结果与理论计算相符。
The concentrating characteristics with the glass thickness of reflector of the solar parabolic trough system are studied by theoretical analysis, simulation, and experiments. The results show that the thicker glass of the reflector and the farther distance of the incident light from the optical axis, the bigger both △X and △y are. The theoretical analysis has been done for the solar parabolic trough system whose focal length is 1200 mm, and the refractive index of glass of reflector is 1.6. For l-ram thickness glass of reflector, when the distance from the optical axis of the incident light is 200 mm and 2000 mm respectively, △X is 0.03 mm and 1.69 mm respectively, △y is 0.19 mm and 0.31 mm respectively. For 5-ram thickness glass of reflector, when the distance from the optical axis of the incident light still is 2000 mm, △X is 8.41 mm, and △Y is 1.55 mm. The theoretical analysis is consistent with TracePro simulation and experiments. The research can provide references to further design of solar parabolic trough system.
