摘要

针对二极管激光器叠阵的高效散热冷却开展了研究, 设计了基于R134a制冷剂的相变冷却系统和以节流式微通道相变冷却方式工作的冷却器, 完成了脉冲功率3 kW叠阵的封装, 并分析了制冷剂在热沉进出口的温度对叠阵出光波长的影响。实验测试结果表明:在20%的高占空比下, 电流197 A时叠阵的输出功率达到3 030 W, 插座效率为39%, 光谱宽度小于3.8 nm, 冷却器内R134a的气化率约为50%。制冷剂R134a的流量为0.60 L/min, 仅为水系统的1/5, 大幅减小了冷却液流量和热管理系统的体积。

Abstract

The paper studies the cooling system of a diode laser stack, and presents a phase transition cooling system using R134a as coolant and a heat sink based on throttle microchannel phase transition cooling. The packaging of the quasi-continuous wave (pulsed) 3 kW laser diode stack is finished. The influence of the temperature difference of coolant at inlet and outlet on the output wavelength of the stack is analyzed. Experimental results show that the stack achieves a 3 030 W peak light-output power with a duty cycle of 20% at a current of 197 A. The wall plug efficiency is 39% and the vaporization rate of R134a in the cooler is 50%. The half width at full maximum of spectrum is smaller than 3.8 nm. The flow rate of the coolant R134a is 0.60 L/min, which is about 20% that of water. Therefore, the coolant flow becomes smaller and the volume of the thermal management unit diminishes significantly.
