Abstract :

In this work an experimental study of cooling capabilities of impinging water and air jet array is presented. Investigations were carried out using electrically heated test plate. Heat flux in the range of 25 to 200W/cm2, which is a typical requirement for cooling high power electronic components was dissipated using 0.25mm and 0.5mm diameter water and air jets arranged in 7X7 array with a pitch of 3mm. Tests were performed in the Reynolds number range of 1200 to 4500. Results shows higher values of heat transfer coefficient are obtained.The effe ct of positioning of jets are insignificant
