Objectives: To enhance heat transfer by using different shaped heat sinks. Method: The results from the experimental forced convection are compared for different heat sinks like honeycomb-shaped, radial-shaped, and flaredshaped. The experiment is conducted by varying the voltage input and the heat dissipation is compared. Also, certain other parameters like surface temperature, Nusselt number, Reynolds number, and effectiveness are found. The heat sink which has greater Nusselt number and heat transfer coefficient along with lower thermal resistance are considered as a comparatively better heat sink. Findings: Experimental analysis shows that the Honey comb shaped heat sink for 100V of voltage input has higher heat transfer coefficient which is more by 20.01% and 22.73%, also shows higher Nusselt number by 9.7% and 8.9% along with decrease in thermal resistance by 20.1% and 22.73% with respect to radial and flared heat sinks respectively. Novelty: It leads to findings of different shaped heat sink, which can be used in electronic components for better heat dissipation.
