“…Comparison between Figures 13 and 15 shows that the addition of perforations to the pin fins in inline arrangement significantly increases heat dissipation from the heat flux at the base plate. This situation is predicted because an increase in effective heat transfer area enhances the rate of heat dissipation [22].…”

Heat sinks play a crucial role in thermal management by dissipating heat away from electronic devices and reducing the device’s performance. The heat sink with pin fins will enhance the rate of convective heat transfer and improve the cooling efficiency of electronic components by increasing the surface area. This study investigates the enhancement of heat transfer rate on square threaded pin fin heat sinks with or without perforation under natural convection. The fins were arranged in inline and staggered arrangement. Four different configurations were designed by using CATIA V5 and simulated by using CFD analysis with different power inputs at 5 W, 10 W and 15 W. The simulation results were validated with the experimental results from the previous study by comparing the heat transfer coefficient of the heat sink design by natural convection. The results show that the average heat transfer coefficient of square threaded pin fins with perforations in staggered arrangement is 7.365 W/m2.oC compared to the pin fins without perforations which is 7.168 W/m2.oC. Therefore, pin fin with perforation dissipates heat at the rate of 2.75% more than pin fin without perforation. In conclusion, the square threaded pin fins with perforations in staggered arrangement have higher heat transfer performance.

“…The Nusselt number was higher for inline pin fin arrangement but the staggered fins showed overall better performance. Ahmad Naufal bin Samsudin et al [11] investigated numerically the change in heat sinks performance and its heat transfer ability by using wings and by varying the number of pin fins. They concluded that addition of wings increases the heat transfer rate drastically from the hot spots.…”

Fins are used to enhance the rate of heat dissipation by increasing convection. The total amount of conduction, convection, or radiation of an object determines the amount of heat it transfers. A pin fin heat sink is acts as a heat exchanger and transfers the heat generated by an electronic or a mechanical device to a fluid medium, where it is dissipated away from the device which helps in proper functioning of device. The present investigation deals with the CFD simulation of heat dissipation and fluid flow behavior of pin fin heat sink with straight and inclined wings. The results show that pin fin with straight wings or wings at 0 degrees dissipate more heat than pin fin with inclined wings at 15 degrees.
