Abstract
An active cooling device in the form of a torsional, oscillating synthetic jet is provided. Fins are oscillated in a manner that creates a flow of air that can be used to cool an electronic device such as a lamp. Embodiments of the active cooling device can be compact and readily incorporated within heat sinks of different sizes and configurations. The flow of air can be provided as jets of air distributed over multiple directions as may be desirable with certain electronics such as an omnidirectional lamp.
Claims19
An active cooling device, the active cooling device defining radial and circumferential directions, the active cooling device comprising:
- a plurality of fins spaced apart from each other along a circumferential direction of the cooling device and rotatable about an axis of rotation;
- a housing defining a plurality of chambers positioned adjacent to each other along the circumferential direction, each chamber defining at least two openings for air flow in and out of the chamber, wherein at least one fin from the plurality of fins is movably positioned within each chamber;
- and
- an oscillating device positioned at least partially within the housing and radially inward of the plurality of fins, the plurality of fins connected with the oscillating device, the oscillating device structured for causing the plurality of fins to rotate back and forth along the circumferential direction so as to create air flow through the openings in each chamber.
An active cooling device, comprising:
- a housing defining an internal compartment and a plurality of chambers positioned proximate to each other along a circumferential direction, the plurality of chambers positioned radially outward of the internal compartment, each chamber of the plurality of chambers having at least two openings spaced apart from each other along the circumferential direction;
- a plurality of fins mechanically connected to each other, each fin positioned in one of the plurality of chambers, the plurality of fins rotatable within the plurality of chambers and about an axis of rotation so as to create a flow of air through the at least two openings;
- and
- an oscillating device positioned at least partially within the internal compartment of the housing and radially inward of the plurality of fins, the plurality of fins connected with the oscillating device, the oscillating device structured for causing the plurality of fins to rotate back and forth along the circumferential direction so as to create air flow through the openings in each chamber.
