Abstract

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

What is claimed is:

1 . An apparatus comprising:
a housing; one or more electrical components disposed within the housing; and a spectrally selective radiation emission device, disposed on the housing, and configured to:
emit radiation at one or more wavelengths of electromagnetic energy corresponding to a far infrared spectrum; and
reflecting radiation at other wavelengths of electromagnetic energy corresponding to a mid-infrared spectrum and a visible spectrum.

2 . An apparatus as described in claim Error! Reference source not found., wherein the spectrally selective radiation emission device is configured to reflect one or more wavelengths of electromagnetic energy that correspond to the near infrared spectrum.

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

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

5 . An apparatus as described in claim 1 , wherein the spectrally selective radiation emission device is configured to emit radiation responsive to the one or more electrical components generating heat during operation.

6 . An apparatus as described in claim 1 , wherein the apparatus is configured such that 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 electrical components.

7 . An apparatus as described in claim 1 , wherein the spectrally selective radiation emission device comprises an outer layer of material that is transparent to the emitted radiation at the one or more wavelengths of electromagnetic energy corresponding to the far infrared spectrum.

8 . A computing device comprising:
a housing; one or more computing device components disposed within the housing; and a spectrally selective radiation emission device, disposed on the housing, and configured to emit radiation at one or more wavelengths of electromagnetic energy corresponding to a far infrared spectrum, and reflect one or more other wavelengths of electromagnetic energy that correspond to a near infrared spectrum.

9 . A computing device as described in claim 8 , wherein the spectrally selective radiation emission device is further configured to reflect one or more wavelengths of electromagnetic energy that correspond to a visible spectrum.

10 . A computing device as described in claim 8 , wherein the spectrally selective radiation emission device comprises an outer layer of material that is transparent to the emitted radiation at the one or more wavelengths of electromagnetic energy corresponding to the far infrared spectrum.

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

12 . A computing device as described in claim 8 , wherein the spectrally selective radiation emission device comprises a paint that is applied to the housing.

13 . A computing device as described in claim 8 , wherein the spectrally selective radiation emission device is configured to emit radiation thereby cooling the one or more computing device components during operation of the computing device.

14 . A computing device as described in claim 8 , wherein the computing device is configured such that 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.

15 . A housing for an apparatus, comprising:
a spectrally selective radiation emission device attached to the housing and including:
a far infrared emissive material configured to emit radiation at one or more wavelengths of electromagnetic energy corresponding to a far infrared spectrum; and
a near infrared reflective material configured to reflect radiation at one or more other wavelengths of electromagnetic energy corresponding to a near infrared spectrum.

16 . A housing as described in claim 15 , wherein the spectrally selective radiation emission device comprises a fabric secured to the housing.

17 . A housing as described in claim 15 , wherein the spectrally selective radiation emission device comprises a paint secured to the housing of the computing device.

18 . A housing as described in claim 15 , wherein the housing is for one or more of a display device, a peripheral device, an electrical charging device, or a power supply.

19 . A housing as described in claim 15 , further comprising one or more electrical components disposed within the housing.

20 . A housing as described in claim 15 , further comprising one or more electrical components disposed within the housing, wherein the spectrally selective radiation emission device is configured such that 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 electrical components.
