Design of the Liquid-Cooling System for High Power LED Modules Using Taguchi Analysis
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.
