Abstract
An air-cooling system (10, 110, 210) utilizing a synthetic jet or airflow generator (20, 120, 220) and airflow generators utilizing piezoelectrics (26, 126, 226) to cool heat-emitting elements (12, 112, 212). Actuation of the piezoelectrics (26, 126, 226) results in movement of one or more flexible structures (22, 24, 122, 124, 221) to increase the volume of one or more cavities (28, 30, 32, 128, 228, 230, 232) to draw air in and then decrease the volume of the one or more cavities (28, 30, 32, 128, 228, 230, 232) to push out the drawn in air.
Claims18
An air-cooling system comprising:
- a heat-emitting element having at least one of an interior or an exterior;
- and
- a piezoelectric air generator having opposed and spaced flexible plates defining a cavity there between;
- wherein the piezoelectric synthetic jet is located either within the interior of the heat-emitting element, where the flexible plates are located within the interior, or about the exterior of the heat-emitting element, where at least a portion of the heat-emitting element extends into the cavity.
An airflow generator for use with an object having at least a first surface and a second surface, comprising:
- a flexible structure having a first side where a first portion of the first side of the flexible structure is spaced from a portion of the first surface of the object to define a first cavity there between and a second portion of the first side of the flexible structure is spaced from a portion of the second surface of the object to define a second cavity there between;
- and
- at least one piezoelectric located on the flexible structure;
- wherein actuation of the at least one piezoelectric results in movement of the flexible structure to increase the volume of at least one of the first cavity or the second cavity to draw air in and then decrease the volume of the first cavity or the second cavity to push out the drawn in air such that the object is cooled by the airflow created by the airflow generator.
An airflow generator for cooling an object having at least a first surface and a second surface, comprising:
- a first flexible structure having a first surface spaced from a portion of the first surface of the object to define a first cavity;
- a second flexible structure having a first surface spaced from a portion of the second surface of the object to define a second cavity;
- and
- a piezoelectric located on each of the first flexible structure and the second flexible structure;
- wherein actuation of the piezoelectrics results in movement of the first flexible structure and the second flexible structure to increase the volume of the first and second cavities to draw air in and then decrease the volume of the first and second cavities to push out the drawn in air.
