Abstract: The project starts from the consideration that, due to the even more strict international standards, the earth moving machineries must be equipped with optimized engines with new and improved devices (liquid cooled EGR valves, new catalytic converters and DPF systems) which reduce the space in the engine compartment. The heat exchanger optimization is needed to obtain smaller, lighter, but at the same time more efficient radiators so that the industry has to modify his production system to be able to answer to the market requests rapidly and with tailored products. The technical feasibility of nanostructured coatings application on the single component of heat exchangers has been explored in the Reference project presented by the same research team in the FDF‒SP1‒1.2 with encouraging results. The present project aims at investigating the effects of nanostructured coatings when deposited on the inner surface of a heat exchanger, in order to improve its overall heat transfer efficiency as expected on the basis of the last literature findings. However, since the most commonly used processes to assemble heat exchanger from single components – e.g. blaze welding – require high temperatures at the moment not consistent with the nature of the coating, the project will evaluate the development of an alternative assembly methodology leading to heat exchangers prototypes with internal superhydrophobic surfaces.
