摘　　要：本文运用微槽群复合相变和热电制冷(TEC)技术来实现激光器系统低温下的高热流密度散热。通过对不同工质在不同充液率下的实验研究发现,工质和充液率对系统的运行状况有重要的影响。在选用甲醇作为循环工质,并且在系统充液率为1.5的情况下,系统能够达到所需的散热冷却效果;本文实验分析了冷凝器的工作状况对蒸发器表面温度的影响,提出通过提高TEC制冷片的制冷量和强化铜散热片的散热能力来降低冷凝器的温度,进而降低蒸发器的温度。High heat flux cooling at subnormal temperature for the lasers on display is realized by using technologies of combined phase-change heat transfer in microgrooves and thermoelectric cooling （TEC） in this paper. An experimental study on the thermal management characteristics of the cooling system is conducted. It is found that the type of working liquid and liquid fill ratio have important influences on the performance of the cooling system. The system can meet the laser＇s cooling demands when working liquid is methanol and liquid fill ratio is 1.5. Through analyzing the relationship between condenser performance and evaporator temperature, it is suggested that enhancing the cooling capacity of TEC and the copper rib plates could reduce the condenser temperature, thereby reducing evaporator temperature.
