Abstract:
1. A fanless high-efficiency cooling device using ion wind, the device comprising: a heat sink having a fixing part fixedly attached to a heat-generating part of an electronic product and a plurality of protrusions extending a predetermined height from a bottom surface of the fixing part; a cover that covers the upper part of the heat sink while exposing both ends of the heat sink to define fluid inlet and outlet channels between the protrusions; at least one electric wire, disposed between one of the protrusions and another adjacent protrusion such that the electric wire extends a predetermined length from one end of the heat sink to the other end of the heat sink while being in parallel with the protrusions, for generating ion wind between the corresponding protrusions when high voltage is applied to the electric wire, the electric wire being made of a conductive material; an electric wire-supporting member that supports both ends of the electric wire; and a power supply that connects a high-voltage terminal to the electric wire and connects a ground terminal to the heat sink to supply high voltage to the electric wire.
