Experimental Study of Heat Pipe Exchanger for High Power LED Cooling System

Abstract:

A new cooling concept for high power LED street lamp by combining the heat release of high power LED with two-phase heat transfer heat pipes was proposed, and in this study a series of heat pipes with specific fins structure were developed. Through experimental results, we found the new heat pipe heat exchangers have the features of higher efficiency of heat dissipation and more compact construction which meets the demand of heat dissipation for high power LED than the traditional heat pipe heat exchangers and the new exchanger with outwards-radiate structure has the best heat dissipation performance.
