Numerical Investigation of Forced Convection Heat Transfer for Different Models of PPFHS Heatsinks

In his research article, several models of heatsink were optimally designed in fin length, width and height along with pin placement which consists of ۴ pin fin heatsink models heatsink (including square with different pin angles, circular, truncated cone, and cone pin heatsinks and one model of the plate-fin heatsink (PFHS)) in order to achieve better thermal performance as well as less energy consumption and were numerically investigated under high air velocity and heat fluxes. Different parameters such as peak temperature, Nusselt number, heat resistance, pressure drop, and energy consumption were compared. The results show that the square PPFHS with the pin angle of ۴۵ degrees has the highest thermal performance compared to the rest of the models while also having the highest pressure drop and energy consumption between the models consuming more than ۲۵۵ and ۳۵۸ percent more energy in order to have the same air velocity in the pathway, while the truncated and the fully formed cone model despite having ۲۵% and ۳۰% less thermal performance, have the least pressure drop between the pin models of the heatsinks and therefore consume the least energy out of the PPFHS.
