摘　　要：太阳能模拟器为高温吸热器、热化学反应器、高温材料等测试提供了稳定可靠、调节灵活的全天候辐射条件。本文介绍了一种高辐射能流的太阳能模拟器,包含19个独立的单元。每个单元包括一盏短弧氙灯(包含椭球面反射灯罩),一台冷却风机和一台电源控制器。每盏灯的输入电流范围是50~150 A,19盏灯的灵活组合使得该设备具有非常宽泛的能流使用范围(10%~100%)。实验通过"Mapping Method"得到了聚焦平面上的能流分布、峰值能流、总功率和转换效率等参数。测试结果表明:该太阳能模拟器的总功率达到了28.95 k Wth,峰值能流为2.33 MW/m2,平均辐射能流为545.54 k W/m2(直径为260 mm焦斑面),电-热转换效率为35%。本文介绍的太阳能模拟器为太阳能高温器件的测试提供了稳定可靠的室内模拟辐射源,为相关实验部件的性能评估提供了一种新的便捷途径。A high flux solar simulator is essential for evaluating the performance of high-temperature receiver,thermochemical reactors and high-temperature materials under controlled and adjustable flux conditions.This paper presents a new high-flux solar simulator with 19 individual units(each consuming 6 kW electricity),and each of them is composed of a xenon short-arc lamp closely-coupled with a truncated ellipsoidal reflector,a cooling fan and an electric power supply.The input current of the single lamp is in the range of 50~150 A and the number of units used is flexible,which is capable to provide wide range of flux on the focal plane(10%~100%).The flux distribution,peak flux,power and conversion efficiency intercepted on a circular target plane are evaluated on the base of flux mapping method.According to the test results,the simulator could achieve 28.95 kWth thermal power,peak flux in excess of 2.33 MW/m2 and average irradiance of 545.54 kW/m2 on the focal area with the diameter of 260 mm.The electric-to-thermal conversion efficiency of the simulator is 35%.A new method for evaluating relevant equipment is provided by the proposed solar simulator with the access to the stable and reliable indoor radiation condition.
