介绍了射流水冷技术并将其应用到高能激光器反射镜的冷却中，设计了射流式水冷镜。采用计算流体力学的方法，利用通用有限元软件ANSYS的流体分析模块FLOTRAN对单孔内射流进行了数值模拟，详细讨论了各孔参数对换热性能的影响，实现了孔参数的优化。结果表明:在水冷镜中采用射流技术可以获得很好的对流换热效果，换热系数可达100 kW/(m2·K)以上，且具有结构简单、可控性强等特点。
Abstract
The jet cooling technology was introduced and used in the cooling of high power laser mirror, then the water jet cooled mirror was designed. Computational fluid dynamics method was adopted to simulate the jet in a hole by the fluid analysis module FLOTRAN of the finite element analysis software ANSYS, then the influence on the capability of heat transfer of the parameters of the hole was discussed and optimization of the parameters was achieved. The results show that great capability of heat transfer can be achieved by using the jet cooling technology, with simple structure and good controllability, and the heat transfer coefficient can be higher than 100 kW/(m2·K).
