  • Patent number: 7545640
    Abstract: A method, apparatus, and system are described for an ionic wind generator. The ionic wind generator may have a first electrode that is elevated off a surface of a device that the ionic wind generator is intended to cool. A first surface of the first electrode is in contact with a first surface of a first post that elevates the first electrode off the surface of the device that the ionic wind generator is intended to cool. The ionic wind generator causes a generation of ions that are then drawn through an interstitial atmosphere from the first electrode to a second electrode to affect a velocity of local flow over the surface of the device between the first electrode and the second electrode. The flow from a forced flow device also affects the velocity of local flow over the surface of the device between the first electrode and the second electrode.

  • Publication number: 20080218968
    Abstract: A winged piezo-fan to dissipate the heat generated by the devices in an electronic system is disclosed. The winged piezo-fan may comprise a piezo-ceramic element and two blades. The blades may be coupled to the piezo-ceramic element, which may change its physical dimension in response to receiving an alternating voltage signal. The blades coupled to the piezo-ceramic element may move upwards and downwards in a direction that is perpendicular to the axis drawn along the length dimension of the blades in response to the changes in the physical dimension of the piezo-ceramic element. The movement of the blades may cause a flapping movement, which may create turbulence in the surrounding air. The turbulence so created may create eddies, which may dissipate the heat generated by the devices positioned close to the winged piezo-fan.
