摘　　要：为了实现高功率半导体激光器连续泵浦源输出,设计一种使用微通道热沉封装多个单管半导体激光器的堆叠结构。基于有限元分析,此结构可以通过辅助热沉和微通道内部圆柱翅片扩展单管半导体激光器的传热渠道,与传统凹槽微通道相比,热传导效果有所增强,优化提出斜翅片结构,控制水流速,调节流体流动从而产生混流效应,进一步改善微通道散热性能,对其封装下的多单管进行功率拟合,理论最大输出功率可达128.75 W,在微通道热沉所需制冷功耗较低的前提下,可以实现多单管半导体激光器连续工作模式下泵浦且满足其散热需求。To realize the continuous pumping source output of high-power semiconductor lasers,we design a stacked structure of multi-tube semiconductor lasers based on a microchannel heat sink packaging.Based on the simulation using finite element analysis software,this structure can expand the heat transfer channel of a single-tube semiconductor laser by assisting heat sink and cylindrical fins inside the microchannel.Additionally,the heat conduction effect is enhanced compared with the traditional groove microchannel.Furthermore,the oblique fin structure is optimized to control the water flow rate and promote the mixed flow effect,further improving the heat dissipation performance of the microchannel and power fitting on multiple single tubes under its packaging.The theoretical maximum output power can reach 128.75 W,which can realize the pumping of multi-tube semiconductor lasers in continuous working mode and meet their heat dissipation needs under the premise of low cooling power consumption required for microchannel heat sinking.
