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.
