摘要
大热流密度散热问题已成为发展高功率激光器的关键技术之一。本文结合我们近年来的研究工作,综述了目前正在应用或正在研究的针对高功率激光器冷却技术的研究现状,主要包括微通道液体对流换热、固体冷却、喷雾冷却和微热管冷却。然后根据技术发展趋势,提出了微通道沸腾换热冷却和液氮冷却是两种具有很好应用前景的冷却技术,并介绍了该两项技术目前基础研究进展情况。
For the high-power solid-state laser, the cooling technology has become one of the key techniques for its development. This paper reviews the current development of cooling technology dealing with the high-power solidstate laser, both in use and in the experimental stage, which includes the liquid convection heat exchange in microchannel, diamond cooling, spray cooling and micro-heat-pipe cooling. On the basis of our recent research and the summarization of the development, we propose two promising cooling methods, boiling heat exchange in microchannel and liquid nitrogen cooling, and discuss the recent progress of theoretical studies on the two techniques.
