Conjugate natural convection cooling of protruding heat sources mounted on a substrate placed inside an enclosure: a parametric study Original Research Article

The present work demonstrates a parametric study for a conjugate natural convection cooled substrate mounted heat sources placed inside an enclosure. This particular situation has direct relevance in electronic cooling applications. The governing coupled non-dimensional transport equations were solved using the finite volume technique. It is found that Ra,Pr and enclosure boundary condition affects strongly the fluid flow and heat transfer characteristics. It is concluded that non- dimensional temperature is maximum for Pr=150. Numerical correlation for maximum protrusion temperature and Nusselt number were presented for wide range of Pr,Ra and enclosure boundary conditions.
