DESIGN OF HEAT SINK WITH CORRUGATED CHANNEL BY THE MODELS OF RESPONSE SURFACE AND NUMERICAL CONJUGATE HEAT TRANSFER
RESUMO
The aim of this study is to optimize the sinusoidal wavy structure of a channel cooler for active cooling with the best heat transfer performance. The wavelength s, amplitude a, wave width b, the channel width between two waves m, and heat sink height u have been determined as geometric design parameters. The optimization was performed by combining the experimentally validated conjugate computational fluid dynamics method with the response surface methodology (RSM). The overall heat transfer index β and the mean temperature of the cooler base T were determined as evaluation criteria to show whether the increase in heat transfer outweighed the increased pressure drop. In addition, the effect of each design parameter on β and T is shown and empirical equations are obtained. The effect of each parameter on the results is determined using an analysis of variance (ANOVA). The results showed that channel width variation for both β and wavelength was the effective primary factor for T. At the optimum design point, β and T were found to be 12.59 and 311.6 K, respectively. At this point, the parameters were found as s = 10, a = 0.55, b = 1.5, u = 18, and m = 3. Simulations for optimum geometry were performed in the air flow rate range from 10 L/min to 35 L/min.
