摘　　要：文中介绍了小型化光纤激光器的热仿真分析和优化设计方法。首先对光纤激光器的热损耗进行了分析,然后依据热力学相关理论,基于ANSYS Icepak软件,对光纤激光器进行了建模和仿真分析。针对小型化光纤激光器小尺寸流道的特点,进行了水冷板结构的仿真分析和散热优化,设计了2 kW级的小型化、轻量化光纤激光器,并开展了实验验证。结果表明,在实现了工作波长为1 080 nm,最大功率为2.2 kW的连续激光输出时,热耗器件安装位置处的最高温度为32.1℃,且光学参数正常。实验结果与仿真结果相符,光纤激光器的整体温度得到了明显改善。文中的仿真和优化设计可为小型化、轻量化光纤激光器的冷却设计提供重要参考。The thermal simulation analysis and optimization design methods of miniaturized fiber laser are introduced in this paper. Firstly, the thermal loss of fiber laser is analyzed. Then, based on the thermodynamics theory and ANSYS Icepak software, the fiber laser is modeled and simulated. According to the characteristics of the miniaturized fiber laser, the thermal optimization design and structure design of the water-cooled plate are carried out respectively. A 2 kW class miniaturized and lightweight fiber laser is designed and verified by experiment. The result shows that when continuous fiber laser output with a work wavelength of 1 080 nm and a maximum output power of 2.2 kW is realized, the maximum temperature at the installation position of the heat consumption device is 32.1℃ and the optical parameters are normal. The experimental results are in agreement with the simulation results. The overall temperature of the fiber laser has been significantly improved. The simulation analysis and optimization design in this paper can provide an important reference for cooling design of the miniaturization and lightweight fiber laser.
