This master thesis presents a study and analysis of liquid-cooled thermal exchange systems for electric traction inverters. The advancement of high-performance microprocessor systems allowed inverter models with greater power density and operating limits. For this, thermal management measures are important to reduce the size of electric traction inverters. The importance of thermal management in power systems is addressed and the impacts on the heat exchange capacity of different heat sinks under operating conditions are evaluated. These impacts are verified from two sink geometries, with evaluation between a finite volume model and experimental tests. Simulations and tests allow the design and dimensioning of heat sinks through thermal parameters and tests on an experimental bench, using an electronic load as a heat source. Simulation and experimental results are performed to evaluate the thermal exchange capacity of heat sinks.
