PERFORMANCE OPTIMIZATION OF A HEAT SINK WITH BRANCHED FINS
Krishna Kumar Singh and M. K. Sinha
|
Abstract: This paper determines the optimum values of the design parameters in a cylindrical heat sink with branched fins. Investigations on the effect of the design parameters, such as the number of fins, length of fin, height of fin, and the outer diameter of the heat sink on heat transfer are reported. In this analysis, branch angle is considered. The Taguchi method, a powerful tool for design optimization, is applied for the tests and standard orthogonal array (OA) with all the three factors and three levels for each factor is selected. Nine test samples are analyzed in which the total heat transfer rate for each test sample is found. Contribution ratios for each parameter are also found. The results obtained from this analysis are employed to find the optimum design parameter values which are related to the heat sink performance. The reliability of the optimum test samples is verified. Also, the variation of the average heat transfer rate of optimum sample is reported, when it is compared with the reference sample. |
