e Simulação Computacional do Sistema de Arrefecimento de Um Veículo Fórmula SAE Elétrico

Abstract

The cooling system plays a fundamental role in the performance and reliability of electric competition vehicles, ensuring the optimal operating temperature of power components such as the motor and inverter. This work presents the design and simulation of a cooling system for a Formula SAE electric vehicle, considering the integration of a reservoir, pump, hoses, heat exchanger, and cooling circuit. Initially, a review of the thermal requirements of the powertrain components was conducted, defining the heat dissipation parameters and the required coolant flow rate. Subsequently, computational modeling of the system was developed using thermal and fluid dynamics simulation software, allowing for an analysis of fluid behavior and heat transfer efficiency under different operating conditions. The results enabled the optimization of the hydraulic and thermal layout of the system, ensuring more efficient and reliable performance. This study contributes to the advancement of thermal system engineering in electric competition vehicles, providing a foundation for future design improvements.
