Abstract
A cooling device generating unidirectional air flow to cool an electrical component. The cooling device is an equivalent of an electrical acoustic diode to make air flow only one direction. A speaker generates air flow in a first passageway to a cavity, and then expels air out from the cavity through a second passageway. An electrical component is cooled by the air flow, and may be positioned adjacent the passageways, or positioned in the cavity. In one example, eyewear having an electrical component positioned in a temple is cooled by the cooling device.
Claims20
A cooling device, comprising:
- a body member having a cavity;
- a first channel section having a first passageway extending from the cavity, wherein the first passageway is tapered from a first input opening directly coupled to the cavity to a first output opening, wherein the first input opening is larger than the first output opening;
- a second channel section having a second passageway extending from the cavity, wherein the second passageway is tapered from a second input opening directly coupled to the cavity to a second output opening, wherein the second input opening is smaller than the second output opening;
- and
- a speaker coupled to the cavity, wherein the speaker is configured to generate an air flow into the second channel section and out the first channel section.
A method of cooling a device having a body member having a cavity, a first channel section having a first passageway extending from the cavity, wherein the first passageway is tapered from a first input opening directly coupled to the cavity to a first output opening, wherein the first input opening is larger than the first output opening, a second channel section having a second passageway extending from the cavity, wherein the second passageway is tapered from a second input opening directly coupled to the cavity to a second output opening, wherein the second input opening is smaller than the second output opening, a speaker coupled to the cavity, comprising:
- energizing the speaker to generate an air flow into the second channel section and out the first channel section;
- and
- cooling an electrical component using the generated air flow.
