In this manuscript we have learned four types of Fin-tube Air-Cooled Heat Exchanger (ACHE) design with rounded inner circles in a separate area with rectangular copper wings. In the proposed design we find the average value of the heat transfer counter for crossing the flow rate of the cooling air of the natural convection exchange is 3010.68 watt, 3110.53 watt, 3129.56 watt and 3151.50 watt in a different grooving area at 0 mm [without , 15 mm, 10 mm and 5 mm respectively. similarly for convection compression values the average heat transfer counter for the flow rate of the cooling air tube is 3044.25 watt, 3125.65 watt, 3154.85 watt and 3190 watt in a different grooving area at 0 mm [excluding grooving], 15 mm, 10 mm and 5 mm respectively. The value of the heat transfer function of the test set, using a rotating aluminum inner tube with rectangular brass fins 6.011, 6.484, 6.891, and 7.485 in a separate grooving hole in the 0 mm eg empty tube (excluding grooving), circle grooving pitch by 15 mm, round grooving pitch by 10 mm and circular grooving pitch by 5 mm respectively .In this experimental setting we check that with the circular heat transfer of the grooving concentric aluminum tube with copper wings is the highest in place 15 mm round clipping
