Synthetic jet driven cooling device with increased volumetric flow

A hybrid coanda-venturi cooling device comprising:

• at least one synthetic jet actuator, each of the at least one synthetic jet actuators configured to generate and project a series of fluid vortices out from an orifice thereof;
• a manifold coupled to the at least one synthetic jet actuator so as to receive the series of fluid vortices therefrom, the series of fluid vortices from the at least one synthetic jet actuator generating a primary air stream;
• an air amplifier connected to the manifold so as to receive the primary air stream, the air amplifier comprising a venturi section having a reduced cross-sectional area as compared to an air intake of the air amplifier;
• wherein a coanda effect acting on the primary air stream as it enters the air amplifier and a venturi effect caused by the venturi section of the air amplifier causes a fluid surrounding the air intake to be entrained into the air intake to generate a secondary air stream, the secondary air stream combining with the primary air stream to provide a combined air flow that exits an air outlet of the air amplifier.

A method of manufacturing a synthetic jet cooling device comprising:

• providing one or more synthetic jet actuators each configured to generate and project a series of fluid vortices out from an orifice thereof;
• coupling a manifold to the one or more synthetic jet actuators so as to receive the series of fluid vortices from the orifices of the synthetic jet actuators, the series of fluid vortices from the one or more synthetic jet actuators generating a primary air stream;
• connecting an air amplifier to the manifold by way of a connecting pipe so as to receive the primary air stream from the manifold, the air amplifier comprising a venturi section having a reduced cross-sectional area as compared to an air intake of the air amplifier;
• wherein connection of the air amplifier to the synthetic jet stack generates an air flow output from the air amplifier having a higher velocity and volumetric flow rate than the primary air stream generated from the one or more synthetic jet actuators.
