The present paper reports the important results of the problem of combined conductionconvectionradiation from a vertical rectangular electronic board equipped with three identical discrete heat sources. The heat sources are located along the vertical central axis of the board. The heat generated in the three heat sources is conducted both along and across the board, before subsequently getting dissipated by convection and radiation. Air, a radiatively transparent medium, is considered to be the cooling agent. The governing partial differential equations for temperature distribution in the entire computational domain are obtained by appropriate energy balance between the heat generated, conducted, convected and radiated. These equations are solved using finite difference formulation coupled with GaussSeidel iterative solver. A computer code is written to solve the problem and exhaustive parametric studies have been carried out. Interactive effect of radiation on conjugate convection has been elucidated.
