【摘要】 高品位太阳能的利用是当今世界太阳能利用的热点,针对太阳到达地面能流密度低的特点,需要采用聚焦的方式加以利用。为了能使入射的太阳能得到更为有效的利用,对聚集到接收面上的能流进行合理的分配非常必要。本文设计制作了一个直径为500 mm的温度测试盘,并将其安装于碟式聚光器上,利用铠装热电偶对该聚光器焦平面上的温度分布情况进行了实验测试,为后期优化设计吸热器提供了参考和依据。更多还原

【Abstract】 The use of high-grade solar energy is the world’s solar energy utilization hotspot.For the characteristics of low energy flux density from which the sun reaches the ground,a focused approach to be adopted.In order to make the incident of solar energy be more efficient,it is necessary to reasonably assign energy flux density which is received by the collector.In this paper,a temperature testing disc of 500 mm in diameter is designed and mounted on the condenser of the dish solar collector.The temperature distribution on the focal plane of the condenser is experimentally tested which lays the reference and basis for the post-optimized for the absorber.更多还原
