Abstract
An airflow generator (10) having a first plate (12), a second plate (14) where the second plate (14) is spaced from the first plate (12) to define a cavity (28) there between, a joint (30) operably coupled to the first plate (12) and the second plate (14) and joining them together, piezoelectrics (34) located on each of the first plate (12) and the second plate (14) wherein actuation of the piezoelectrics (34) results in movement of the first plate (12) and the second plate (14) to increase the volume of the cavity (28) to draw air in (200) and then decrease the volume of the cavity (28) to push out the drawn in air (202).
Claims14
An airflow generator, comprising:
- a first plate having a first surface and a second surface;
- a second plate having a first surface and a second surface wherein the first surface of the second plate is spaced from the first surface of the first plate to define a cavity there between;
- a joint operably coupling the first plate and the second plate;
- and
- at least one piezoelectric located on each of the first plate and the second plate;
- wherein at least one of the first plate or the second plate includes a plurality of recesses;
- and
- wherein the plurality of recess surround and are spaced from the at least one piezoelectric located on the at least one of the first plate or the second plate, and
- wherein at least one recess of the plurality of recesses includes at least one dimple extending away from the at least one of the first plate or the second plate to increase a volume of the cavity.
