摘要

摘要: 针对高热流密度激光介质高效散热与均匀冷却技术需求，设计并搭建了以去离子水为冷却工质的开式单喷嘴喷雾冷却实验平台，实验研究获得了不同热流密度（16～110 W/cm²）、不同冷却工质流量（200～300 mL/min）以及不同喷雾高度（15～25 mm）下单相喷雾冷却换热系数及其冷却均匀性效果。结果表明：该实验工况下，不同热流密度条件下喷雾高度及工质流量对于单相喷雾冷却换热效率及温度均匀性影响显著；喷雾高度15 mm、工质流量200 mL/min时获得最大对流换热系数为5.93 W/（cm²·K）；喷雾高度15 mm、工质流量250 mL/min时面积20 mm×20 mm的热源表面温度均匀性最佳可优于0.6 ℃。

Abstract: Aiming at the requirements of efficient heat dissipation and uniform cooling for high heat flux laser medium, an experimental platform of open single nozzle spray was designed and established by using the deionized water as cooling medium. The spray cooling heat transfer coefficients and cooling uniformity effect in the single-phase region were obtained at different heat flux (16～110 W/cm²), flow rates (200～300 mL/min) and spray heights (15～25 mm). It is concluded from the experimental results that the cooling efficiency and temperature uniformity were significantly affected by the spray height and flow rate under different heat flux. The maximal heat transfer coefficient of 5.93 W/(cm²·K) was got at the spray height of 15 mm and flow rate of 200 mL/min, while the temperature uniformity could be greater than 0.6 ℃ with the heating area of 20 mm×20 mm at the spray height of 15 mm and flow rate of 250 mL/min.
