Abstract

A computing device having a spectrally selective radiation emission device is described. In one or more implementations, an apparatus includes a housing, one or more electrical components disposed within the housing, and a spectrally selective radiation emission device. The one or more electrical components are configured to generate heat during operation. The spectrally selective radiation emission device is disposed on the housing and configured to emit radiation when heated by the one or more electrical components at one or more wavelengths of electromagnetic energy and reflect radiation at one or more other wavelengths of electromagnetic energy.

First claim

emitting radiation, when heated by the one or more electrical components, at one or more wavelengths of electromagnetic energy, the one or more wavelengths of electromagnetic energy corresponding to a far infrared spectrum;
reflecting radiation at one or more other wavelengths of electromagnetic energy, the one or more other wavelengths of electromagnetic energy corresponding to a near infrared spectrum; and
reflecting one or more wavelengths of electromagnetic energy that correspond to a visible spectrum.

2. An apparatus as described in claim 1 , wherein the spectrally selective radiation emission device includes a fabric that is secured to the housing.

3. An apparatus as described in claim 1 , wherein the spectrally selective radiation emission device includes a paint that is applied to the housing.

4. An apparatus as described in claim 1 , wherein the approximate operating temperature is between thirty and fifty degrees Celsius.

5. An apparatus as described in claim 1 , wherein a surface temperature of the housing is higher than a surface temperature of the spectrally selective radiation emission device during operation of the one or more computing device components.

6. An apparatus as described in claim 1 , wherein the spectrally selective radiation emission device includes an outer layer of material that is transparent to the emitted radiation at the one or more wavelengths.

7. A computing device comprising:
a housing formed according to a hand-held form factor that is suitable to be held by one or more hands of a user;
one or more computing device components disposed within the housing, the one or more computing device components generating heat at an approximate operating temperature to perform one or more computing device operations; and
a spectrally selective radiation emission device, disposed on the housing, emitting radiation when at the approximate operating temperature at one or more wavelengths of electromagnetic energy thereby cooling the one or more computing device components during operation of the computing device, the one or more wavelengths of electromagnetic energy corresponding to a far infrared spectrum and the spectrally selective radiation emission device reflecting at least one or more other wavelengths of electromagnetic energy that correspond to a near infrared spectrum.

8. A computing device as described in claim 7 , wherein the spectrally selective radiation emission device includes a fabric that is secured to the housing.

9. A computing device as described in claim 7 , wherein the spectrally selective radiation emission device includes a paint that is applied to the housing.

10. A computing device as described in claim 7 , wherein the approximate operating temperature is between thirty and forty degrees Celsius.

11. A computing device as described in claim 7 , wherein a surface temperature of the housing is higher than a surface temperature of the spectrally selective radiation emission device during operation of the one or more computing device components.

12. A method comprising:
securing a spectrally selective radiation emission device to a housing of a computing device such that the housing is suitable to be held by one or more hands of a user; and
positioning one or more computing device components within the housing, the one or more computing device components generating heat, during operation, at an approximate operating temperature, thereby causing the spectrally selective radiation emission device to emit radiation at one or more wavelengths of electromagnetic energy thereby cooling the housing and reflecting radiation at one or more other wavelengths of electromagnetic energy, the one or more other wavelengths of electromagnetic energy correspond to a near infrared spectrum and the one or more wavelengths of electromagnetic energy that are emitted correspond to a far infrared spectrum.

13. A method as described in claim 12 , wherein securing the spectrally selective radiation emission device to the housing of the computing device includes securing a fabric to the housing of the computing device.

14. A method as described in claim 12 , wherein securing the spectrally selective radiation emission device to the housing of the computing device includes securing a paint that to the housing of the computing device.

15. A method as described in claim 12 , wherein the approximate operating temperature is between thirty and forty degrees Celsius.

16. A method as described in claim 12 , wherein a surface temperature of the housing is higher than a surface temperature of the spectrally selective radiation emission device during operation of the one or more computing device components.

17. An apparatus as described in claim 1 , wherein the apparatus comprises one of a display device, a peripheral device, an electrical charging device, or a power supply.

18. A computing device as described in claim 7 , wherein the computing device comprises a tablet or a wireless phone.
