In this study, the application of heat sinks for cooling heat loads in a commercial aircraft is investigated. An outer skin heat exchanger is modeled numerically and examined. For this purpose, a suitable CFD (computational fluid dynamics) model of the heat exchanger is developed and validated. A well-founded evaluation of different geometry variants of the heat exchanger liquid side is carried out using the generated model. Subsequently, the designed geometries are evaluated with regard to their weight properties, which are of vital importance in the application of commercial aircraft. The received information at component level in combination to a defined cooling system architecture is used as an input for a developed overall system design methodology. Within this framework, a multi-criteria evaluation of the overall system level will show the influence of parameter variation on a component level and its effect on the overall system level for a regional aircraft. In particular, the required power demand, the resulting system weight and the induced aerodynamic drag are considered. Subsequently, an integration analysis of the selected system architecture is performed and evaluated in terms of plausibility.
