초록
The study will design the structural optimization of 30W LED heat sink using the thermalconductive plastic materials. The advantages of thermal conductive plastic heat sink are having formabilityand being able to lighten products. A heat sink was optimized in terms of the number, and the thicknessof fins and the base thickness of the heat sink, using the Heatsinkdesigner software. Also by usingSolidWorks Flow simulation and thermal analysis software, the thermal characteristics of the heat sinkwere analyzed. As the result, the optimized heat sink has 22 fins, which are 1.5mm thick and a3.8mm-thick base. The weight of the heat sink was 310g, and the highest and the lowest temperaturewere 64.93℃ and 45.96℃ respectively. Because of the low thermal conductivity of the thermalconductive plastic, the highest and the lowest temperature of the thermal conductive plastic heat sinkwere 14.3℃ higher and 2.19℃ lower respectively than an aluminum heat sink.
