Ionic wind heat sink

Abstract

An ionic wind heat sink includes a heat-dissipating structure and a high-voltage generator. The high-voltage generator is configured to output a positive high-voltage surge and a negative high-voltage surge. The high-voltage generator has a positive high-voltage end and a negative high-voltage end. A first electrical wire is electrically connected to the positive high-voltage end, and a second electrical wire is electrically connected to the negative high-voltage end. The two electrical wires generate an ionic wind flowing toward the heat-dissipating structure. With this arrangement, the whole mechanical construction of the heat sink can be simplified. The noise, vibrations and electricity consumption can be reduced, while the heat of a heat-generating source can be taken away efficiently.
