Abstract: This work presents an investigation of the thermal performance on Thermo-siphon charged with norflurane as a running fluid, with electro chemical nano coating. This analysis was carried out to scrutinize the optimized fill ratio and angle of inclination for better heat transfer enhancement. The fluctuation of heat transfer ability of the thermo-siphon was analyzed for the input heat transfer rate varies from 0 to 350 W for various filling ratios and inclination of angle. The various fill ratio of the refrigerant used in the analysis are 70%, 60%, 50%, 40% and 30% and angle of inclination for carrying out orientation analysis were taken as 0°, 45° and 90°. Experimental results showed that the fill ratio and orientation analysis showed a better heat transfer performance on thermo-siphon while using Norflurane as a working fluid. Experimental investigations and calculations depicted that the thermal resistance of 50% fill ratio was found to be lower than that of other fill ratios thereby leading to a better thermal performance for thermo-siphon charged with Norflurane. Further, upon further investigation for orientation analysis it was found that the horizontal inclination provided better heat transfer. Hence this present investigation indicates that the thermal performance of a thermo-siphon can be enhanced using Norflurane at an optimal fill ratio of 50% and at an angle of inclination of 0°
