    Abstract: A synthetic jet includes a first backer structure and a first actuator coupled to the first backer structure to form a first composite unit. The synthetic jet also includes a second backer structure, and a second actuator coupled to the second backer structure to form a second composite unit. A wall member is coupled to and positioned between the first and second backer structures to form a cavity. The first composite unit has an orifice formed therethrough and the orifice is fluidically coupled to the cavity and fluidically coupled to an environment external to the cavity.

    Abstract: A synthetic jet driven cooling device includes at least one synthetic jet actuator to generate and project a series of fluid vortices. A manifold coupled to the synthetic jet actuator(s) receives the fluid vortices and generates a primary air stream. An air amplifier connected to the manifold by a connecting pipe receives the primary air stream. The air amplifier includes an air intake oriented perpendicular to the connecting pipe and an air outlet positioned opposite the air intake, with a venturi section positioned between the air intake and air outlet that has a diameter smaller than the air intake diameter. A low pressure region in a center of the venturi section entrains a surrounding air in through the air intake to generate a secondary air stream that combines with the primary air stream to generate a combined air flow that flows through the venturi and exits the air outlet.

    Abstract: A system and method for lowering resonant frequency in a synthetic jet device for less noise, as well as lowering vibration, is disclosed. A synthetic jet device includes a first plate, a second plate spaced apart from the first plate, a spacing component coupled to and positioned between the first and second plates to form a chamber and including an orifice therein, and an actuator element coupled to at least one of the first or second plates to selectively cause deflection thereof, wherein the first and second plates are formed at least in part of a non-metallic material.

    Abstract: A system and method for reducing or increasing the mechanical structure resonance of a synthetic jet device is disclosed. A synthetic jet device includes a first plate, a second plate spaced apart from the first plate, a spacing component coupled to and positioned between the first and second plates to form a chamber and including an orifice therein, and an actuator element coupled to at least one of the first and second plates to selectively cause deflection thereof, thereby changing a volume within the chamber so that a series of fluid vortices is generated and projected out from the orifice of the spacing component. At least one of the first and second plates includes a modified section that alters a mechanical resonance of the synthetic jet device, so as to control a level of acoustic noise generated by the synthetic jet device.
