Abstract

Light Emitting Diode(LED) lighting is one of the well-known energy efficient and rapidly developing technologies.LED lighting has a longer lifespan,higher durability and better light quality if have a good cooling performance of heat sink.The purpose of this research is to optimize the geometry of heat sink without increasing production cost to achieve high performance of heat sink without using excessive materials.The experimental work of the study will be expensive. Therefore,software simulation Ansys version 16 was used to simulate the case study.In order to validate the simulation were correct,comparison of the experimental and numerical result was done.Once the difference between them was not huge,case study proceeded.After several case studies were done,it found out that reduce in fin thickness of heat sink and increased in height of fin of heat sink had the highest cooling performance of heat sink compared to the others.This is because reduce in fin thickness resulted the thermal boundary layer did not fully develop at an early stage.While increase in fin height resulted in a huge increase in surface area, therefore,heat transfer surface area greatly increased. This study will be used for geometry optimization of the heat sink with another shape.
