The Simulation Study on Heat Dissipation of High Power LED Based on the Natural Convection

Abstract:

In this paper, we studied on the heat dissipation of high power LED in numerical simulation by the large eddy simulation numerical methods with the simulation software FDS, and studied the temperature distribution and heat pipe cooling respectively, etc.. We did the numerical simulation research on the heat dissipation of high power LED fin by numerical simulation, and obtained the numerical solution of all the LED temperature field and flow field. The air flow rate near the radiating surface was low; the fin surface temperature distribution was basic uniform and closed to the temperature of the constant heat reservoir. The analysis of the results of numerical simulation provided references for the improvement of optimal design of LED radiator.
