Computer-aided Analysis of Thermal Convection near Electric Devices

摘要

Current-carrying capacity of the electric devices depends to a large extent on the intensity of the heat transfer to the environment [1-6]. The heat transfer is influenced by the thermal conductivity of the device insulation and by the thermal resistance of convection from the device surface to the environment. For instance, the current-carrying capacity I_z of an insulated conductor may be determined by (1).
