Impingement cooling method utilizes high speed jet(s) to impinge on a high temperature surfaces for cooling or heating. In this study, various heat sink geometrical configurations – Heat sink with no fins, Heat sink with continuous platefins, Heat sink with interrupted plate-fins, Heat sinks with pin-fins – were studied. The studies had been conducted for three jet velocity (2, 4 and 6 m/s) as well as three Z/d ratio of 2, 4 and 6. Numerical simulations for this work had been performed in ANSYS… Expand
