Abstract

A RTICLE I NFORMATION A BSTRACTOriginal Research PaperReceived 19 June 2016Accepted 12 July 2016Available Online 28 August 2016Effects of different INLET/OUTLET ARRANGEMENTS on thermal performance of POROUS MICROchannel heat sinkMCHS of any geometry has not been studied yet. In this investigation, the effects of utilization of fourdifferent INLET/OUTLET ARRANGEMENTS on electronic chip COOLING utilizing trapezoidal MCHS with porousmicrochannels with porosity of 0.88 have been studied numerically. For this purpose, three dimensionalsimulations of laminar forced convection flow in microchannels and conduction in solid parts of MCHSby applying constant heat flux of 150 kWm -2 at its base plate have been performed utilizing the finitevolume method and the commercial Ansys-CFX code. The results show that the A- and B-typearrangements, for which the inlet and outlet are in direction of flow in the microchannels, have a betterheat transfer performance, smaller thermal resistance and provide more uniform temperaturedistribution in the MCHS base plate. The results indicate that using porous media is effective inreducing the MCHS base plate temperature and in this regard the D-type arrangement has the bestperformance among the heat sinks studied. Considering both the positive effect of using porous mediaon increasing the heat transfer coefficient and its negative effect on increasing the required pumpingpower, the A-type arrangement has the best performance.
