Analysis on Heat Transfer Characteristic in Micro-channel with High Heat Flux

  • 摘要: 冷却散热问题一直是制约高热流密度激光器进一步发展的关键问题,对于传统的冷却方法,其散热均很难以突破100 W/cm2。介绍了几种以水为工质的微通道液冷散热器结构,并重点分析研究了基于V型槽的微通道冷板结构。利用有限元分析软件,对影响换热效率的冷却工质入口流速,微通宽度,占空比进行了分析,并对分歧管的结构位置作了进一步改进,以改善最高表面温度分布均匀度。通过有限元软件的特征分析,结果表明:基于V型槽的微流道冷板,用水为冷却工质时,其散热能力可高达500 W/cm2。
