Abstract Scope |
Recently, appling LED(Light-emitting diode) headlight to the automobile has been increasing and the trend has also led from luxury cars to low and mid-price cars because of its advantages; great energy efficiency, longer life, eco-friendly, and its ability to provide positively influencing vehicle design.
But, LED performance and lifetime are strong factors of its temperature. Therefore, the effective cooling of LED light system is very important issue.
In this study, forged aluminum heat sink(A1050) which has cylindrical pins' arrangement that extended from its base was produced and its performance was compared with an existing straight fin heat sink(ADC12) which was produced by die casting process.
Results show that although the surface area of forged heat sink was 189cm² while die casting heat sink had 268cm², its performance was better than die casting heat sink. Moreover, the weight of forged heat sink reduced 30% compared to die casting heat sink.
