Numerical and experimental investigation of thermal convection near electric devices with vertical channels
This paper presents the results of numerical and experimental investigation of thermal convection near heat emitting surfaces of an electric device. For the intensification of thermal convection, special vertical channels were formed near the heat emitting surfaces of the device. An experimental test has proved that there is an optimal length of the channels - thermal convection is the most intensive then. Air velocity vectors close to heat emitting surfaces are presented with the use of Ansys software. Due to vertical channels, it is possible to increase the current-carrying capacity of electric devices.
