Customized Heat exchanger with Improved Nano-coated surface for earthmoving machines Applications (CHINA) Final report

The project starts from the consideration that, due to the increasingly strict international standards, the earth moving machineries will be provided of optimized engines with new and improved devices (liquid cooled EGR valves, new catalytic converters and DPF systems) which reduce inevitably the space in the engine compartment. An heat exchanger optimization is needed to obtain smaller, lighter, but at the same time more efficient radiators than the current ones and the industry has to modify its production system to be able to answer to the market requests rapidly and with tailored products. The potential of the application of structured coatings on a nanoscale, has been exploited in another project (SNAPP) presented by the same research team in the FDF-SP1-1.2 with encouraging results. This project aims to investigate the potential of surface nano-coatings on the heat transfer surface of heat exchangers, in order to improve the overall efficiency, in terms of pressure drop and heat power developing also an optimized production system.
