In this paper. is present a new model for heat transfer calculations during airflow through the finned tubes bank in air cooled condenser systems (ACC). The model was correlated with a total of 736 sets of available experimental data provided by ten authors of recognized prestige in the research area. The air flow bathes a package of finned tubes with an inclination of 450 to 600 with respect to the horizontal line. The studies were performed for ST/SL intervals between 0.4 and 2, air flow velocity of 0.1 to 20 m/s, an ambient temperature of 15 to 43 °C, the incident wind speed over the installation between 0 and 45 km/h, the outer equivalent diameter of the bare tubes between 0.019 and 0.035 m, a height of the fins between 2.7 and 7.5 mm. thicknesses of the fins ranging between 2.3 and 3 mm and a number of fins per unit tube length between 315 and 394. The mean deviation found was 6.5% in 84.8% of the correlated experimental data.
