建立了具有石英窗口的太阳能高温吸热器的能量传递与转换模型,采用谱带辐射传递因子描述太阳光与热辐射能束的传输特性。结合谱带模型,通过蒙特卡洛射线踪迹法模拟,得到谱带辐射传递因子。在此基础上,分析了太阳能高温吸热器的热转换特性,考察了石英窗口的光学性能参数与吸热芯温度分布对太阳能高温热转换的影响,获得了对太阳能高温吸热腔设计有参考价值的结果。
A model of energy transfer and conversion of solar heat sink with quartz window was established. The band radiation transfer factor was used to describe the transmission characteristics of solar beam and thermal radiation beam. Combined with the band model, Monte Carlo ray tracing method was used to simulate the band radiation transfer factor. On this basis, the thermal conversion characteristics of the solar heat absorber were analyzed. The influence of the optical performance parameters of the quartz window and the temperature distribution of the heat sink on the solar heat conversion was investigated. The design of the solar heat absorber was obtained The value of the result.
