The cooling of a racing car is an important aspect that has significant implications for both its reliability and performance. In an extremely competitive championship like Formula Student, a properly sized cooling system is essential for achieving excellent results in dynamic events. The purpose of this master’s thesis is to design a radiator assembly for the Politecnico di Torino SC26 Formula Student car. To achieve this, it was necessary to analyze the car’s design targets in order to understand how the radiator assembly could help achieve them. The results were the targets of the cooling system and, as a consequence, the targets of the radiator assembly.
