Optimization of fins arrangements for the square light emitting diode (LED) cooling through nanofluid-filled microchannel

Abstract In current paper, a finned micro-channel is designed for the cooling application in Light Emitting Diode (LED), numerically using Galerkin weighted residual Finite Element Method (GFEM). Selected materials for LED-chip is GaN, Die from Si, Die-attach is made by Au-20Sn, substrate is copper...
