Design and Thermal Analysis of LED Lamp Cooling by using Optimization of Circular Fins

Abstract

The selection of particular fin configuration in LED Lamp for heat transfer application depend on the  weight and manufacturing technique consideration as well as the thermal characteristics it exhibits, Circular Fins are one of the most popular choice for enhancing the heat transfer rate to Minimize an junction temperature by minimizing the total thermal resistance of system. For actively cooled systems,  this may essentially be achieved by simultaneously engineering the conduction through the heat sink and creating a well-designed flow pattern of Heat over suitable convective surface area. Finite element method (FEM) was used to compute the maximum temperature at junction of LED. An extensive study was carried out using ANSYS, a powerful platform for Heat flow through Led Heat sink. Results obtained were presented in a series of temperature along the length of fins.
