Abstract

An apparatus for shielding an electronics enclosure is disclosed. The apparatus includes an inner enclosure that houses electronic components. An outer enclosure surrounds the inner enclosure, and is separated from the inner enclosure by a gap. The outer enclosure preferably comprises plastic, and comprises a plurality of perforations uniformly distributed over its surface. The plurality of perforations allow air to flow into the gap between the outer enclosure and the inner enclosure. At the same time, the perforations are configured and dimensioned such that they substantially prevent sunlight from directly striking the surface of the inner enclosure. In this manner, the apparatus prevents overheating of the electronic components while minimizing the space taken up by the enclosure.

Claims

1. An apparatus for enclosing electronics, comprising:

an outer enclosure having a plurality of perforations substantially uniformly distributed about its surface; and

an inner enclosure positioned within the outer enclosure, wherein the inner enclosure has one or more electronic components selectively positioned inside;

wherein the outer enclosure is configured and dimensioned to be spaced from the inner enclosure.

2. The apparatus of claim 1, wherein each of the plurality of perforations substantially prevent sunlight from directly striking an outer surface of the inner enclosure.

3. The apparatus of claim 1, wherein each of the plurality of perforations allow air to pass to the space between the inner and outer enclosure.

4. The apparatus of claim 1, wherein about 95% or more of the sunlight that strikes each of the plurality of perforations from an angle of about 45 degrees or more, relative to normal, are substantially prevented from striking a surface of the inner enclosure.

5. The apparatus of claim 1, wherein the outer enclosure comprises plastic.

6. The apparatus of claim 1, wherein the width of the perforations is between about 5.5 mm and about 6.5 mm.

7. The apparatus of claim 1, wherein the height of the perforations between about 2.5 mm and about 3.5 mm.

8. An apparatus for enclosing electronic components, comprising:

a first housing having one or more electronic components selectively positioned therein; and

a second housing configured and dimensioned to enclose the first housing;

wherein the second housing includes a plurality of perforations that substantially prevent sunlight from directly striking the first housing.

9. The apparatus of claim 8, wherein the plurality of perforations are uniformly distributed about the surface of the second housing.

10. The apparatus of claim 8, wherein the second housing comprises plastic.

11. The apparatus of claim 8, wherein the thickness of the second housing is between about 2.5 mm and about 3.5 mm.

12. The apparatus of claim 8, wherein the second housing is spaced from the first housing.

13. The apparatus of claim 12, wherein the space between the second housing and the first housing is between about 10 mm and about 14 mm.

14. The apparatus of claim 8, wherein:

the height of the perforations is between about 2 mm and about 4 mm; and

the width of the perforations is between about 4 mm and about 8 mm.

15. An apparatus for enclosing electronic devices, comprising:

an inner enclosure having one or more electronic devices positioned inside; and

an outer enclosure configured and dimensioned to surround the inner enclosure;

wherein the inner enclosure is separated from the outer enclosure by a gap;

and wherein the outer enclosure comprises a plurality of perforations, wherein each of the plurality of perforations allow air to enter the gap.

16. The apparatus of claim 15, wherein the outer enclosure comprises plastic.

17. The apparatus of claim 15, wherein the plurality of perforations are uniformly distributed on the surface of the outer enclosure.

18. The apparatus of claim 15, wherein the plurality of perforations substantially prevent sunlight from directly striking a surface of the inner enclosure.

19. The apparatus of claim 15, wherein between about 80% and about 100% of the sunlight that strikes the outer enclosure from an angle of about 45°

or more relative to normal is prevented from directly striking a surface of the inner enclosure.

20. The apparatus of claim 15, wherein the gap is between about 8 mm and about 16 mm.
