Abstract :
In this paper, a 3D thermal model that couples thermal and flow fields of a high-power, high-frequency oil-immersed transformer was presented. The thermal model including a set of conservation equations was solved using the finite volume method. The temperature and oil flow velocity distribution are of interest. Natural convection is the mechanism of heat dissipation. The results show that the conditions of natural convection were dependent on the physical shapes of the heat sink and transformer.
