Abstract

The disclosed wireless router may include (i) an enclosure, (ii) an antenna, (iii) a printed circuit board assembly, (iv) a radiative heat sink disposed between the antenna and the printed circuit board assembly within the wireless router such that the radiative heat sink is configured to shield the antenna from spurious emissions generated by the printed circuit board assembly, and (v) a fan disposed at a center of the radiative heat sink such that the fan is configured to cool the wireless router by circulating air within the enclosure rather than pushing air through venting in the enclosure. Various other apparatuses, systems, and methods are also disclosed.

Claims (31)

1. A wireless router comprising:

an enclosure;

an antenna;

a printed circuit board assembly;

a radiative heat sink disposed between the antenna and the printed circuit board assembly within the wireless router such that the radiative heat sink is configured to shield the antenna from spurious emissions generated by the printed circuit board assembly; and

a fan disposed at a center of the radiative heat sink such that the fan is configured to cool the wireless router by circulating air within the enclosure rather than pushing air through venting in the enclosure.

2. The wireless router of claim 1 , wherein the enclosure substantially lacks venting.

3. The wireless router of claim 2 , wherein the enclosure is substantially air impermeable.

4. The wireless router of claim 1 , wherein the fan is configured to cool the wireless router through forced convection.

5. The wireless router of claim 4 , wherein the wireless router is configured to perform cooling primarily through forced convection rather than natural convection.

6. The wireless router of claim 1 , further comprising a temperature sensor.

7. The wireless router of claim 6 , wherein the wireless router is configured to activate the fan in response to the temperature sensor detecting a temperature over a threshold value.

8. The wireless router of claim 1 , wherein the radiative heat sink is separated from the enclosure by a gap of space to inhibit the radiative heat sink from heating the enclosure.

9. The wireless router of claim 8 , wherein the gap of space surrounds a horizontal planar edge of the radiative heat sink.

10. The wireless router of claim 1 , wherein the radiative heat sink substantially fills a horizontal plane of the wireless router to maximize surface area of the radiative heat sink.

11. The wireless router of claim 1 , wherein the radiative heat sink is disposed between the antenna and the printed circuit board assembly along a vertical axis of the wireless router.

12. The wireless router of claim 1 , wherein the radiative heat sink is placed within a horizontal plane within the enclosure that is substantially optimized in circumference to maximize surface area of the radiative heat sink.

13. The wireless router of claim 1 , wherein the radiative heat sink comprises at least one fin.

14. The wireless router of claim 13 , wherein the fin extends vertically up from a horizontal plane of the radiative heat sink.

15. The wireless router of claim 13 , wherein the fin extends radially along a horizontal plane from the fan at the center of the wireless router.

16. The wireless router of claim 13 , wherein:

the radiative heat sink comprises a plurality of fins; and

each of the plurality of fins extends radially along a horizontal plane from the fan at the center of the wireless router.

17. The wireless router of claim 1 , wherein a shape of the enclosure is substantially spherical.

18. The wireless router of claim 17 , wherein a shape of the enclosure forms a geodesic polyhedron.

19. A wireless router cooling system, comprising:

a radiative heat sink disposed between an antenna and a printed circuit board assembly such that the radiative heat sink is configured to shield the antenna from spurious emissions generated by the printed circuit board assembly; and

a fan disposed at a center of the radiative heat sink such that the wireless router cooling system is configured to perform cooling primarily through forced convection rather than natural convection.

20. A method comprising:

disposing a radiative heat sink between an antenna and a printed circuit board assembly within a wireless router such that the radiative heat sink is configured to shield the antenna from spurious emissions generated by the printed circuit board assembly; and

disposing a fan at a center of the radiative heat sink such that the fan is configured to cool the wireless router by circulating air within an enclosure of the wireless router rather than pushing air through venting in the enclosure.
