Component and engine cooling module heat transfer testing in dedicated computer-interfaced wind tunnels allows the measurement of heat rejection and internal and external fluid pressure drop. This empirical data serves as the base for cooling module performance simulations, which further supports Climatic Vehicle Wind Tunnel testing. This information helps to maximize individual heat exchanger and cooling module system performance and provides a simple, repeatable test that can be performed in continuous conformance testing to ensure that TitanX heat exchangers provide the expected heat transfer over the entire life of the product.
