The main result of this study is to propose a liquid-cooling system for high power LED heat dissipation treatment. By using thermal dissipation mechanism and based on ANSYS CFX numerical analysis of change the parameters of cold plat. We will get the optimal heat dissipation structure. The experimental results show that the Taguchi method of thermal mechanisms in this study of the four control factors affecting the order: k value of thermal compound > fan power > liquid type > pump flow rate, and to identify the best combination of factor levels. When the heat source is 90 W, the best factor of the experimental cooling system thermal resistance is 0.563K/W. Nomenclature

Liquid Cooling System

To optimize thermal dissipation efficiency for cooling high power LED modules is studied and analyzed using ANSYS CFX software and Taguchi method. In liquid-cooling system, four control factors are tested and compared in order to find the best cooling arrangement that are pump flow rate, fan power, cooling liquid type and k- value of thermal compound. The experimental results show that the importance of these cooling parameters applied to high power LED module are k-value of thermal compound, fan power, liquid type and pump flow rate in sequence. For a constant heating power of 90W from an LED lighting module, an optimal thermal resistance of 0.563K/W is obtained that shows a significant improved result then the conventional LED module’s. It has high potential in future high power LED applications.

Two Phase Heat Transfer

A new cooling concept for high power LED by combining the heat release of high power LED with two-phase heat transfer heat pipes was proposed, and in this study a new type of heat pipe with specific fins structure was developed. Through experimental results, we found the new heat pipe heat exchanger has the features of high efficiency of heat dissipation and compact construction which meets the demand of heat dissipation for high power LED. We also found the heat dissipation performance of the HP heat exchanger changed with the work angle.
