Experimental Study of Effect Factors on Performance of Heat Dissipation of HP Heat Exchanger for 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 paper we study the effect of heat pipe numbers, fins structure and ambient temperature on the performance of heat dissipation of HP heat exchanger. Through experimental results, we found the heat pipes number plays a more importent role on the performance of heat dissipation than the fins material and the final surface temperature will increase with the environmental temperature.
