Increased elliptical surface area gives Elliptical Annular Fins an edge in heat transmission. This concept enveloped EAF with Multi-Walled Carbon Nano Tubes to improve convective heat transmission, the primary goal. The coated and uncoated surfaces were compared for convective heat transfer. This research examines fin efficiency, thermal conductivity, and temperature dispersion. Empirical evidence shows that carbon nanotube coated EAF transmits 9% more heat than uncoated fins. Empirical and computational approaches differ in shaped tube and fin efficiency within an acceptable range. Additionally, the Shape Factor is expected to significantly affect the fin’s surface temperature.
