Thermal convection of nano-liquid in an electronic cabinet with finned heat sink and heat generating element

Abstract

Development of electronic devices depends on cooling techniques. An efficiency of cooling methods can be improved using more effective heat-transfer fluids and extended heat-exchange surfaces. Free convection of alumina nanoliquid in a chamber with a copper finned thermal sink and a thermally-producing unit is simulated in the present research. Basic equations written by means of non-dimensional non-primitive characteristics have been solved using the finite difference method. Influences of the Rayleigh number, fins height and nanoparticles concentration on energy transport and flow structures within the chamber have been scrutinized. It has been ascertained that a rise of the fins height and particles concentration intensifies the heat removal from the heated source.
