    摘要:

    本研究设计了一种针对高功率半导体激光器散热问题的干冰微粒喷雾冷却散热器,并利用FLUENT软件对其热流场进行了模拟仿真。得出:入口带有多出口喷嘴的散热器,冷流体在针柱的扰动后对高功率半导体激光器的散热效果最好。干冰流速为0.5m/s,稳定后的温度为24.79℃。实验测试与模拟仿真结果对比,得出最大比较误差分别为8.3%、8.8%。此外,与微通道水冷相比,干冰冷却降温的激光器整体温度低,电光转换效率大,沿垂直条宽方向温度分布均匀,热应力小“smile”效应减弱。研究结果为开发高功率水平阵列半导体激光器干冰冷却打下基础。

    Abstract:

    In this study, a dry ice particle spray cooling heat sink for a high-power semiconductor laser heat dissipation problem is designed and its heat flow field is simulated using FLUENT software. It is concluded that the heatsink with multiple outlet nozzles at the inlet has the best cooling effect of the cold fluid on the high-power semiconductor laser after the perturbation of the needle column. The dry ice flow rate is 0.5 m/s and the temperature after stabilization is 24.79°C. Comparison of the experimental tests with the simulation results yielded maximum comparative errors of 8.3% and 8.8%, respectively. In addition, compared with the microchannel water cooling, the overall temperature of the dry ice-cooled laser is low, the electro-optical conversion efficiency is large, the temperature distribution is uniform along the vertical strip width direction, and the thermal stress is small and the "smile" effect is weakened. The results of the study have laid the foundation for the development of dry ice cooling for high-power horizontal array semiconductor lasers.
