High end design of cooling components requires both detailed analysis with CFD and 1D system simulation. CFD for detailed optimization of all thermodynamic characteristics of the heat exchangers and 1-D simulation for the evaluation of such a heat exchanger in its entire cooling environment (i.e. vehicle simulation). This paper describes the intensive use of CAE-tools for the development of tube/fin systems for higher performance density heat exchangers. As an example the successful optimization of a 52 mm depth radiator system for truck applications is shown. Key element for the virtual design is the parametric CFD capability which allows a thorough understanding of the influence of various parameters. Complete evaluation of heat exchanger performance needs both, heat transfer and pressure drop characteristics. The new winglet tube in combination with an optimized louvered fin (parallel-type) reduces coolant inlet temperature for a given engine heat load and increases the cooling performance of approximately 5.5 % compared to the current radiator design for critical low speed, high engine load operation points. The use of the described CAE-tools is the key for both quality and development speed increase.
