摘要
针对高功率光纤激光器在空间等特殊环境下无水冷却的热管理要求, 设计并研制了一种基于相变材料的高功率光纤包层光滤除器。采用正十八烷作为相变材料吸收包层光滤除器的产热, 利用Ansys的Fluent模块仿真分析相变材料的相变过程及200 W下滤除器温度分布特性, 实验采用0.246 kg质量分数为99%的正十八烷对200 W级滤除器进行热管理, 在室温为25.6 ℃、滤除的包层光为206 W的情况下, 该滤除器可稳定、安全工作360 s。实验结果和仿真结果基本吻合。
Abstract
A high power fiber cladding optical filter with phase change material is designed and developed for the thermal managements of high power fiber laser in the space and other special environments. The phase change material of 18-alkanes is applied to absorbing cladding light heat. The Fluent module of Ansys is used to simulate the phase change process of phase change material and the temperature variation of the stripper at 200 W. 18-alkanes with the mass of 0.246 kg and the mass fraction of 99% is used as the phase change material. The experiment verifies that the stripper can work stably for 360 s at the room temperature of 25.6 ℃ and the light power of 206 W. The simulation results are basically coincident with the experiment.
