仿植物蒸腾作用的高热流密度散热的研究

摘要仿照植物蒸腾作用原理，利用毛细结构和相变技术研究高热流密度的散热问题。以发光二极管（Light Emitting Diode，LED）作为散热对象、乙醇溶液作为相变工质，考察了不同种类毛细材料特性和材料厚度对散热效果的影响。实验结果表明，毛毡材料价格便宜、加工方便，能够把LED的温度降到80℃。毛毡材料的厚度以8~12 mm为宜，乙醇溶液体积分数在80%以上散热效果更佳。

Abstract： Based on the principle of plant transpiration, the heat dissipation of high heat flux was studied by capillary structure and phase change technology. The effects of material properties and thickness on heat dissipation were investigated with light emitting diode (LED) and different concentrations of ethanol. The experimental results show that cheap and easy-to-prepare felt material can reduce the temperature of LED to 80℃. The suitable thickness is 8~12 mm, and the heat dissipation effect is better if the volume fraction of ethanol solution is above 80%.

Keywords： high heat flux； plant transpiration； capillary structure； enhanced heat transfer
