针对大型太阳模拟器光源过热造成光学系统特性不稳定或者丧失的实际问题,以大型太阳模拟器中的散热器为研究对象,通过其热传导分析,建立其三维立体模型,并构建出气工作状态下的数学模型,运用有限元分析方法,设定优化区域值,对散热量、结构与质量构成的多目标参数进行优化设计。优化结果实现了散热器质量不大于16kg时,散热量不小于11000 W的优化目标,所研究方案为大型高温工作的光学设备研制提供了一种有效设计方法。
Aiming at the practical problem of instability or loss of optical system characteristics caused by overheating of large solar simulator light source, the heat sink in large solar simulator is taken as the research object. Through its heat conduction analysis, the three-dimensional model is established and the gas working condition is established Mathematical model, the finite element analysis method is used to set the optimum regional value, and the multi-objective parameters of heat dissipation, structure and quality are optimized. The optimization result achieves the optimization goal that the heat dissipation is not less than 11kg when the mass of the radiator is not more than 16kg. The research project provides an effective design method for the development of optical equipment for large-scale high-temperature operation.
