Abstract EN
The present study investigates the thermal performance of a multiple micro-jet impingements model for electronics cooling.
The fluid flow and heat transport characteristics were investigated for steady incompressible laminar flow by solving three-dimensional (3D) Navier-Stokes equations.
Several parallel and staggered micro-jet configurations (ie.
inline 2 × 2, 3 × 3 and 4 × 4 jets, and staggered five-jet and 13-jet arrays with the jet diameter to the channel height ratios from 0.25–0.5) were analyzed at various flow rates for the maximum temperature rise, pressure drop, heat-transfer coefficient, thermal resistance, and pumping power characteristics.
The parametric investigation was carried out based on the number of jets and the jet diameters at various mass flow rates and jet Reynolds numbers.
Temperature uniformity and coefficient of performance were evaluated to find out the trade-off among the various designs investigated in the present study.
The maximum temperature rise and the pressure drop decreased with an increase in the number of jets except in the case of staggered five-jet array.
A higher temperature uniformity was observed at higher flow rates with a decrease in the coefficient of performance.
The performance parameters, such as thermal resistance and pumping power, showed a conflicting nature with respect to design variables (viz.
jet diameter to stand-off ratio and interjet spacing or number of jets) at various Reynolds numbers within the laminar regime.
