Cross flow heat exchangers are very common in automotive vehicle thermal management systems. The most important and standard fitment of any vehicle is the radiator, a cross flow heat exchanger for engine cooling systems. As a vehicle manufacturer, selection of a cooling system based on the requirements is very critical especially when the radiators are sourced from multiple sources and of different configurations. So, these different types of radiator have to be compared on the same level for effective selection of heat exchangers. This demands the common methodology to be created to understand the heat exchanger performance with different geometrical input from different sources. In this study, an empirical cum analytical based methodology has been developed for generating the performance characteristics of the louvered fin heat exchanger using the thermal resistance and Number of Transfer Units (NTU) method.
