Performance of special type heat sink with an integrated synthetic jet actuator

The performance of special type heat sink with integrated synthetic jet actuator has been presented in this work. Synthetic jet is a flow technique which synthesizes stagnant air to a form of jet. Synthetic jet produces high turbulent flow and thus high heat transfer coefficient can be achieved. Standard heat sink with fan have limited applications in particular in a dusty industrial environment. Therefore, the use of new flow technique is optimistic. The paper presents preliminary results of heat sink thermal power and characteristic temperatures during synthetic jet switched on and off. The results show that under synthetic jet switched on, the dissipated heat is 3.7 times higher than when synthetic jet is switched off
