This paper describes numerical analyses on conjugate heat transfer of laminar air flow from vertical parallel plates with discrete heat sources. The problem is related to the cooling of electronic equipment. Two-dimensional Navier-Stokes and energy equations which include heat conduction in the plates are solved numerically. The conduction heat transfer in the plates reduces both the maximum temperature and convective heat flux of each heat source, and the degrees of reduction depend on the thermal conductivity ratio of the plate to air. The local Nusselt numbers at positions of maximum temperature are correlated by using relevant non-dimensional parameters. The correlation expression can predict the maximum temperature of each heat source within 5% error.
