为准确掌握太阳炉焦点位置光斑能流密度分布情况,需对其进行实际测量。通过相应小朗泊靶能流密度测试仪对该位置光斑能流密度分布情况进行测量,太阳光斑能流密度分布会受到多种因素的影响,比如太阳辐照、表面形状误差、风速、聚光器镜面安装精度因素等。通过小朗泊靶能流密度测试仪实际测量太阳炉聚焦位置光斑能流密度值,软件模拟计算出整个光斑能流密度值,更加接近实际值。从而作为评价聚光器聚光性能的关键指标,进而优化聚光器设计。
In order to accurately understand the distribution of spot energy density at the focal point of the solar furnace, it is necessary to make actual measurements. Through the corresponding Xiaolangd target energy density tester to measure the spot light flux density distribution of the spot, the spot energy density distribution will be affected by many factors, such as solar radiation, the surface shape error, wind speed, concentration Mirror installation accuracy factors. Through the small Langaloo target current density tester, the spot energy density of the solar furnace was measured, and the energy density of the entire spot was simulated by the software, closer to the actual value. As a key index for evaluating the condenser performance, the condenser design is optimized.
