A heat sink with ionic wind has been developed in this study for a new cooling device of a Light Emitting Diode (LED). The characteristics of the ionic wind using wire to parallel-plate-electrodes were analyzed using the Computational Fluid Dynamics (CFD) technique suggested in this study. Also, the cooling performance of the heat sink applied by the impinging flow of the ionic wind was investigated by parametric studies. The CFD results were verified from the experimental results of the ionic wind velocity and temperature. A developed prototype of the heat sink with the ionic wind was then manufactured and tested for its cooling performance. Finally, the advantages of the heat sink with the ionic wind for cooling the LED were confirmed. (C) 2015 Elsevier Ltd. All rights reserved.
