Abstract

Power dense electrical machines are usually liquid cooled; however, this creates a more complex system, involving fluid pumps and heat exchangers: where possible direct air-cooling should be considered. Air speed, turbulence intensity and detailed coil geometry have a direct impact upon the cooling performance of stator windings. These three factors are used to investigate the heat transfer performance of stator windings using 3D Computational Fluid Dynamics (CFD). Great care has been taken to model the anisotropic thermal properties of the coils, enabling the CFD simulations to present an accurate model validated in wind tunnel experiments. Small changes to the geometry are shown to improve the cooling performance of the winding by 44%.
