Synthetic jet driven cooling device with increased volumetric flow

摘要

A synthetic jet driven cooling device 50 includes at least one synthetic jet actuator 10 to generate and project a series of fluid vortices. A manifold 54 coupled to the synthetic jet actuator(s) 10 receives the fluid vortices and generates a primary air stream. An air amplifier (58) connected to the manifold (54) by a connecting pipe 56 receives the primary air stream. The air amplifier 54 includes an air intake 64 oriented perpendicular to the connecting pipe 56 and an air outlet 66 positioned opposite the air intake 64, with a venturi section 62 positioned between the air intake 64 and air outlet 66 that has a diameter smaller than the air intake diameter. A low pressure region in a center of the venturi section 62 entrains a surrounding air in through the air intake 64 to generate a secondary air stream that combines with the primary air stream to generate a combined air flow that flows through the venturi 62 and exits the air outlet 66.
