N2 - The current study focuses on investigating of the performance of inclined microjet array to reduce the temperature of electronic devices. The capacity of the inclined jet arrays has been investigated through a computational fluid dynamics analysis for incompressible laminar flow to find out surface temperature, pressure drop, and flow chaos for the change in jet spacing and diameter, which is related to the number of jets under the constrained heat sink volume. Five different jet arrays consisting of 4, 5, 9, 13, and 16 jets were investigated for different jet diameters. The jet inclination kept constant at 45° to the impingement surface. The results show that the average exit liquid temperature increases with increasing the number of jets. The effects also manifest as the number of jets increases the pressure drop reduces monotonously for all jet diameters under constant mass flow rate in the module. Inclined microjet impingement heat sink having 13 jets showed better potential than the other microjet array configurations.
