摘要
本文通过模拟传热模型,建立起激光器风冷系统的换热基本方程式.分析指出:仅当热阻主要集中于光泵浦——冷却质一侧时,增加循环工作物质密度才有提高换热效果、减小流动阻力、降低风机耗功的明显效果.在此基础上研制成功重复率为10c/s,热耗散功率200W的激光器中压气体封闭循环风冷系统.实验研究所用气体压力P、流速W、壳体外壁侧热阻等诸因素对冷却效能影响的结果亦与分析结论一致.
By using a Simulated model, this article established the basic heat transfer equations for laser-gas cooling systems. It can be used in the determination of heat resistance of each part in the system. Analysis indicates that increase in the circulating gas density can improve the heat transfer effect, decrease gas flow resistance and reduce power consumption. On this basis a medium pressure gas cooling system was built and succeasfuly used in a YAG laser which has a repetition rate of 10 Hz and heat dissipation power of 200 W.
