Thermal Performance of a Plate Fin Heat Sink with Half Round Pins using CFD
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2020, Vol 4, Issue 6
Abstract
As electronic devices continue to advance towards high performance and miniaturization measurements, heat dissipation problems have become a major obstacle to their growth. Moreover, the conventional method of air cooling did not fulfil the heat dissipation criterion of high density. Many scientists have researched the thermal efficiency of heat sinks, but the effects of half round pins on plate fin heat sinks have not yet been explored in the best possible way. In this work, a CFD model is developed to evaluate the effect of half round pin on the thermal performance of plate fin heat sinks, compared with literary experimental data. Here in this work, a constant heat flux of 18750W m2 along with a variable value of inlet air flow i.e. 0.00092, 0.00218, 0.0033 and 0.00433 kg s has been applied. In particular, the plate fin heat sink subject to impinging flow was compared to the conventional design Plate fin heat sink without half round pins . Variation of conventional thermal resistance is compared with the approach proposed in the air mass flow rate of different values. The results of this study show that the base temperature along with the thermal resistance of the heat sink with half round pin is lower for the proposed design. Nusselt number in proposed approach is found to be 28.98 higher than the conventional design at various values of the air mass flow rate due to increase in average heat transfer coefficient. Therefore, the developed approach has strong potential to be used to improve the thermal performance of heat sinks and hence to develop more advanced effective cooling technologies.
