Synthetic jet arraying device

The invention discloses a synthetic jet arraying device and belongs to the field of fluid mechanic flowing control. The synthetic jet arraying device comprises vibration mechanisms, cavities and a cover plate. Each vibration mechanism comprises a plurality of vibration units. Each vibration unit comprises a magnet, a coil, a rigid vibration basin and an outer frame. A cavity plate is provided witha plurality of through holes. One vibration unit is mounted in each through hole. A signal generator inputs periodic electric signals to the coils of the vibration mechanisms, and the coils are madeto move back and forth in magnetic fields of the magnets to drive the rigid vibration basins to vibrate to squeeze and expand the air in the cylindrical cavities, so that air flow is periodically blown and sucked at jet nozzles of the cover plate to generate macroscopic jet flow. The synthetic jet arraying device adopts the modular design and has the advantages of being compact in structure and convenient to install and fa
