中文摘要：
介绍了1种新型金属-塑料复合微结构散热器,并将其应用到LED散热中.通过FloEFD软件,针对不同结构形式的散热器设计进行了数值模拟和比较研究.模拟试验结果表明：金属-塑料复合微结构散热器可以替代全金属散热器,且在加工成本、重量、结构设计、节能减排等方面具有优势.LED芯片的结温达到了设计要求温度60℃以下.
英文摘要：
A new type heat radiator,metal-plastic composite microstructurc heat radiator,and its application in LED heat dissipation were introduced. Through FloEFD software,the numerical simulation and the comparative study had been carried on according to different structure forms of radiator design. The results showed that the metal-plastic composite mierostrueture heat radiator could replace metal heat exchanger and had advantages in the processing cost, weight, structural design, energy saving and emission reduction,etc. The LED junction temperature had reached the design requirements below 60℃.
