THERMAL ANALYSIS OF HEAT SINK WITH FINS OF DIFFERENT CONFIGURATION USING ANSYS WORKBENCH 14.0
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 6
Abstract
The effect of the pin-fin shapes on the overall performance of the heat sink with inline and staggered arrangement is studied in this paper. Six different shapes of fins rectangle, trapezoidal, rectangular interrupted, square, circular inline and staggered are subjected to study in this paper. The optimization processes are carried out using computer simulations performed using Ansys workbench 14.0. TheHeat transfer taken in natural air and aluminum 6063 as a pin fin material. To study of thermal performance of different heat sink of the different fin profile at different velocities 5, 10 & 12 m/s and simulation is done at different heat load of 15W, 20W & 25 W and air inlet temperature is taken as 295 K. The purpose of this study is to examine the effects of the configurations of the different pin-fins design. It is observed from the results that optimum cooling is achieved by the heat sink design which contains Circular pin fins. After the selection of proper heat sink by CFD simulations the steady state thermal performance is carried out at different fin height of circular pin fin heat sink. The result shows that the temperature is increasing by decreasing the fin height. At different loads the performance of all selected fin profiles is carried out and found that at & 25 W load the maximum temperature is maximum for interrupted rectangular fin and minimum for circular pin fin. And the value of Nusslet number is also maximum for circular pin fin design.
