Synthetic Jet Actuator Equipped With A Piezoelectric Actuator And A Viscous Seal

摘要

A synthetic jet ejector (201) is provided which includes a housing (203). A blade (205) is disposed in the housing which has a first fixed end (207) and a second movable end (209), and which is driven by an actuator to trace out a first volume as its free end moves between a first apex and a second apex. The housing has a first portion which is spaced apart from, and complimentary in shape to, at least a portion of the first volume. The spacing (217) between this volume and the first portion is sufficiently small to form a viscous seal around the periphery of the actuator.

1. A synthetic jet ejector, comprising:
a housing; a blade disposed in said housing, said blade having a first fixed end and a second movable end; and an actuator disposed on said blade;wherein said actuator oscillates said blade so that said blade traces out a first volume as the second end of said blade moves between a first apex and a second apex, wherein said housing has a first portion which is spaced apart from, and complimentary in shape to, at least a first surface of said first volume, and wherein the spacing between said first volume and said housing is sufficiently small to form a viscous seal around the periphery of said actuator.
