In this article, we experimentally and analytically studied the heat transfer characteristics of a louver finned automotive radiator. These automotive radiators are one of the most critical devices in the engine cooling systems. These are fluid-gas type heat exchangers, where the fluid phase is cooling fluid, which heated in the engine block, and the gas phase is air from the wind edge. These radiators are commonly used in every vehicle from the simplest scooter to the trucks, but their size is highly depending on the performance of the engine. This study would like to summarize the theoretical background of the louver finned heat exchangers, to show the expressions to calculate the heat performance of the constructions. For the measurements, an experimental setup was made. The airflow provided by fans. In the function of the frequency of the current, the mass flow rate across the fan can be variable. From the results of the measurements, an analytical calculation method can be developed, which fitted to the empirical results.
