摘要:
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.

A synthetic jet ejector (201) is provided which includes a housing (205) having an orifice (207) defined in a wall thereof from which a synthetic jet (209) is emitted, and a barrier (211) disposed about the orifice. The barrier has a first end which is disposed proximal to the orifice and which has a first perimeter. The barrier also has a second end which is disposed distal to the orifice and which has a second perimeter. The second parameter has a larger area than the first perimeter.

A synthetic jet ejector (101) is provided herein which comprises a diaphragm (119), a first voice coil (121) disposed on a first side of said diaphragm, and a second voice coil (123) disposed on a second side of said diaphragm.
摘要:
One embodiment of a thermal management system comprises a heated body, where a heat energy is contained within this heated body. This first embodiment also comprises an ambient fluid adjacent to an exterior surface of the heated body. Walls forming a channel are disposed within an interior of the heated body. The heat contained in the heated body is moved into at least one of these channel walls. The first embodiment comprises a synthetic jet actuator adjacent to one of the channel walls. The synthetic jet actuator is positioned so as to direct a synthetic jet flow through the channel. The operation of the synthetic jet actuator creates a flow consisting of the ambient fluid though the channel. This flow of ambient fluid cools the walls of the channel and thereby also cools the heated body itself.
