摘要
应用热力学第一定律和第二定律对高倍聚光能量转换系统进行分析,发现系统对外输出功率最大时的集热温度为2464 K,提高能量综合利用效率存在较大的潜力,高倍聚光是有效解决手段。并对太阳能集热器形面设计和传输过程分析,满足最佳集热温度条件的抛物镜的相对口径为0.5,传输光纤的最大传输能力的接受半角约为40°。
In this study,the first law and the second law of thermodynamics are used to analyze the energy conversion of a solar concentrator with high concentration ratio,it is founded that the optimal collector temperature is 2464 K under which the maximum power outputs can be obtained,It is of great potential in improving the energy conversion efficiency comprehensively and high concentration of solar radiation is an effective measure.The analysis on the shape of solar concentrator and the process of light transfer shows that relative caliber is of 0.5 under optimal temperature,and the acceptable angle is of 40°within the maximum transmission capacity.
