Summary

Thermo/hydraulic characteristics are obtained through numerical simulations considering a low-permeability aluminium alloy porous layer and air, water and polyalphaolefin as coolants. A theoretical estimate of the global pressure drop across the cold plate is also obtained and compared with the numerical results. The microporous cold plate provides subtantially more uniform operating temperatures for identical components in all module housings than a cold plate without a porous layer. Results also suggest an increased global heat transfer coefficient reducing the operational temperature of the electronics for the same waste heat.
