Abstract
An air agitator assembly for use with a heat-emitting object having a contour, the air agitator assembly including a perforated flexible structure having a thermally absorbing first side confronting and spaced from a portion of the heat-emitting object to define an air space there between and a second side opposite the first side and where at least a portion of the first side of the perforated flexible structure has a contour that matches a contour of a corresponding portion of the heat-emitting object.
Claims20
An air agitator assembly for use with a heat-emitting object having a contour, comprising:
- a perforated flexible structure having a thermally absorbing first side confronting and spaced from a portion of the heat-emitting object to define an air space there between and a second side opposite the first side and where at least a portion of the first side of the perforated flexible structure has a contour that matches a contour of a corresponding portion of the heat-emitting object;
- and
- at least one piezoelectric structure located on the perforated flexible structure and operably coupled to a power source;
- wherein heat emitted from the heat-emitting object is absorbed by the first side and actuation of the at least one piezoelectric structure results in movement of the perforated flexible structure to move the volume of the air located between the hot source and the agitator assembly with the local ambient air.
An air agitator assembly for use with a heat-emitting object having at least a first side and a second side, comprising:
- a first air agitator having a first perforated flexible structure having a thermally absorbing first side spaced from a portion of the first side of the heat-emitting object to define a first air space there between and a second side opposite the first side, where at least a portion of the first side of the first perforated flexible structure has a contour that matches a contour of a corresponding portion of the second side of the heat-emitting object, and at least one piezoelectric structure located on the first perforated flexible structure;
- and
- a second air agitator having a second perforated flexible structure having a thermally absorbing first side spaced from a portion of the second side of the heat-emitting object to define a second air space there between and a second side opposite the first side, where at least a portion of the first side of the second perforated flexible structure has a contour that matches a contour of a corresponding portion of the second side of the heat-emitting object, and at least one piezoelectric structure located on the first perforated flexible structure;
- wherein heat emitted from the heat-emitting object is absorbed by the first side of the first perforated flexible structure and the first side of the second perforated flexible structure and actuation of piezoelectric structures results in movement of the corresponding first perforated flexible structure and the corresponding second perforated flexible structure to move the air such that the heat-emitting object is cooled by airflows created.
