The idea behind the project concerns the study and feasibility analysis of the realisation of cooling systems for power electronics by means of plates made using the Additive Manufacturing technique. The development of the project will include the finite element simulation of the cooling systems designed to assess the thermal, fluid-dynamic and mechanical performance of the structures and a comparison of different construction layouts. A cooling system will be studied that, using these plates, can allow optimal cooling of the entire converter. AM demonstrators of the designed structures will then be built, and a prototype converter will be constructed to demonstrate that the assumptions made during the study phase are actually achieved. An important part of the project will be the electrical, thermal and mechanical characterisations that will be performed on the converter prototype in an operational environment to validate the entire solution.
