Abstract

This paper presents numerical and experimental investigation on optimal placement of discrete heated blocks under forced convection. Flowing air velocities of 0.6–1.4 m/s have been used for cooling of heated blocks in a vertical channel. Three-dimensional laminar developing flows over-heated blocks, representing integrated circuit components for electronic cooling, have been studied using conjugate heat transfer. Experiments are conducted for FR4 and bakelite as substrate board materials having thermal conductivities of 0.3 and 1.4 W/m K to study the fluid flow and heat transfer characteristics with effects of substrate thermal conductivity. Finite element-based software is used to solve the coupling between heat transfer in solids and fluid region. The air cooling of substrate boards mounted with heated blocks is modeled and simulated to present heat transport in combination with the fluid flow resulting from the forced air circulation at velocities 0.6–1.4 m/s at constant heat flux values of 1500, 2000, and 2500 W/m2. The optimal configuration that gives maximum heat dissipation is identified. Experiments indicate a deviation of under 5% with simulations.
