  • Synthetic jet ejector for the thermal management of PCI cards
    Publication number: 20070119573
    Abstract: A method for constructing a thermal management system is provided herein. In accordance with the method, a fan (405) is provided which is adapted to provide a global flow of fluid through the device. A synthetic jet ejector (409) is also provided which is adapted to augment the global flow of fluid over the surfaces of a heat sink (403). The ratio of the flow per unit time of the synthetic jet ejector to the flow per unit time of the fan is selected so as to achieve a desired level of heat dissipation.

  • Apparatus and method for enhanced heat transfer
    Publication number: 20060060331
    Abstract: One embodiment of the system is implemented as a device for two-phase heat transfer. This device comprises a chamber containing a fluid, where a heated wall makes up a portion of the chamber. The device also comprises an actuator that emits pressure vibrations. The pressure vibrations dislodge vapor bubbles that form at the heated wall due to the heat in the wall.
