Abstract

A system for stabilizing, moderating and/or controlling the temperature of an outdoor enclosure, such as a network interface device, using room-temperature air from the associated building. A fan draws the room temperature (or moderate-temperature) air through a conduit from the interior of the dwelling to the outdoor enclosure. The outdoor enclosure is temperature-stabilized as indoor air flows through it. The air may flow through the same conduit that accommodates the data lines. A power line for the fan may be located in the same conduit. The system may be arranged to prevent insects and contaminants from entering the enclosure.

Claims

1. A system for controlling the temperature in a network interface device, said system comprising:

an outdoor enclosure for enclosing said network interface device, said outdoor enclosure having an opening, said outdoor enclosure being located on a wall of a building; and

a fan for causing room temperature air to flow from said building, into said outdoor enclosure, and through said opening.

2. The system of claim 1, further comprising a conduit for flowing air into said enclosure.

3. The system of claim 1, wherein said outdoor enclosure includes plastic.

4. The system of claim 1, further comprising a power source for said fan.

5. A system for controlling the temperature in a network interface device, said system comprising:

an outdoor enclosure having an opening; and

a fan for causing room temperature air flow into said outdoor enclosure and through said opening; and

wherein said outdoor enclosure contains electronic devices and signal lines, said signal lines extending out of said enclosure through said opening.

6. The system of claim 5, wherein said opening is configured to prevent contaminants from entering said outdoor enclosure.

7. The system of claim 5, wherein said fain and said opening are sized to prevent insects from entering said outdoor enclosure.

8. A system for controlling the temperature in a network interface device, said system comprising:

an outdoor enclosure having an opening;

a fan for causing room temperature air to flow into said outdoor enclosure and through said opening; and

a power source for said fan, and wherein said power source supplies direct current to said fan at no more than about forty volts.

9. The system of claim 8, further comprising a power line located between said power source and said fan, said power line being located in said conduit.

10. The system of claim 9, further comprising data lines located in said conduit, said data lines being connected to electronic components.

11. The system of claim 10, further comprising a cover located within a dwelling, said cover having one or more opening for said air, said power line and said data lines.

12. A method of operating an outdoor enclosure attached to a building, said method comprising the steps of:

causing room temperature air to flow from the interior of said building, into said outdoor enclosure, and then through an opening in said outdoor enclosure; and

communicating signals through data lines from said outdoor enclosure and into said interior of said building.

13. The method of claim 12, wherein said step of causing air to flow includes the step of operating a fan located within said enclosure.

14. The method of claim 12, wherein said building includes a residential dwelling.

15. The method of claim 12, wherein said step of causing air to flow into said enclosure includes the step of flowing air through a conduit formed in a wall of said building.

16. The method of claim 15, wherein said data lines are located in said conduit.

17. The method of claim 16, wherein said air flowing through said conduit is cooler than the outdoors temperature.

18. The method of claim 17, wherein said step of flowing air through said opening includes the step of preventing insects from entering said enclosure.

19. The method of claim 16, wherein said air flowing through said conduit is warmer than the outdoors temperature.
