摘　　要：风冷散热是大功率激光广泛应用的一个至关重要的技术问题。随着激光手持焊、激光清洗等应用范围越来越广,激光风冷散热也变得更加困难起来。在文章中,将热管安装在冷却热沉板上,并在散热片上重新安装热管,以便利用热管的传热原理。利用风冷散热器模拟热负载,并使用ANSYS有限元分析软件进行仿真模拟,以研究热沉板中嵌入热管后激光模块器件的温度场分布情况。经过频率红移法的实验验证可发现,这种方法在风冷散热系统中能够获得良好的散热效果。通过模拟发现,热管与高功率半导体激光器风冷技术相结合可以克服水冷技术在复杂环境中的局限性,为高功率半导体激光器的散热问题带来新的解决方案。Air-cooled heat dissipation is a key technical problem in the wide application of high power laser.With the more and more wider application of laser hand welding and laser cleaning,it is more difficult for laser air cooling to dissipate heat.In this paper,the heat pipe is installed on the cooling heat sink plate,and reinstalled on the heat sink fins in order to enhance the cooling of high-power laser.Also,thermal simulation analysis of air-cooled semiconductor laser module is carried out based on ANSYS finite analysis software.Through the experiments of frequency redshift method,it is found that this method can obtain good heat dissipation effect in air cooling system.Moreover,the results show that combining heat pipes with high-power semiconductor laser air-cooling technology can overcome the limitations of water-cooling technology in complex environments,thus bringing new solutions to the problem of heat dissipation in high power semiconductor laser.
