This study aims to analyze the influence of Reynolds number velocity and heating power on the staggered tube arrangement toward the thermo-hydraulic performance of an air-cooled cross-flow heat exchanger. This experimental study employed test air velocities varying from 4–28 m/s and three heating power variations of 20, 30, and 40 W. Measurements included pressure drop (ΔP), logarithmic mean temperature difference (ΔTlm), convective heat transfer coefficient (h), and Nusselt number (Nu). The measurement results indicate that the pressure drop increased significantly with increasing flow velocity, whereas the logarithmic mean temperature difference decreased. Meanwhile, the convective heat transfer coefficient and Nusselt number were found to increase along with the increase in Reynolds number.
