Abstract

Sealed camera apparatus may include a generally closed chamber having at least one transparent window provided therein. A video camera mounted within the generally closed chamber receives light transmitted through the at least one transparent window. A radio transmitter mounted within the generally closed chamber is operatively associated with the video camera. A heat conduit having a first end and a second end extends through an opening provided in the generally closed chamber so that the first end of the heat conduit is located interior to the generally closed chamber and so that the second end of the heat conduit is located exterior to the generally closed chamber. The first end of said heat conduit is in thermal contact with at least a portion of the radio transmitter so that heat from the radio transmitter is transferred to the heat conduit. A heat sink mounted to the second end of the heat conduit dissipates heat from the transmitter and conducted through the heat conduit.

Claims

1. A sealed camera apparatus, comprising:

a generally closed chamber having at least one transparent window provided therein;

a video camera mounted within said generally closed chamber so that said video camera receives light transmitted through the at least one transparent window provided in said generally closed chamber;

a radio transmitter mounted within said generally closed chamber, said radio transmitter being operatively associated with said video camera;

a heat conduit having a first end and a second end, said heat conduit extending through an opening provided in said generally closed chamber so that the first end of said heat conduit is located interior to said generally closed chamber and so that the second end of said heat conduit is located exterior to said generally closed chamber, the first end of said heat conduit being in thermal contact with said radio transmitter so that heat from said radio transmitter is transferred to said heat conduit; and

a heat sink mounted to the second end of said heat conduit, said heat sink dissipating heat from at least said radio transmitter and conducted through said heat conduit.

2. The apparatus of claim 1, wherein said generally closed chamber comprises a waterproof chamber.

3. The apparatus of claim 1, wherein said heat conduit comprises a generally cylindrically shaped member.

4. The apparatus of claim 1, further comprising a gasket operatively associated with said heat conduit and said generally closed chamber, said gasket sealing a gap between said heat conduit and said generally closed chamber.

5. The apparatus of claim 4, wherein said gasket comprises an O-ring.

6. The apparatus of claim 1, wherein said heat conduit comprises aluminum.

7. The apparatus of claim 1, wherein said heat sink comprises a plurality of fins.

8. The apparatus of claim 1, wherein said heat sink comprises aluminum.

9. The apparatus of claim 1, wherein said heat conduit lacks a liquid heat transfer fluid.

10. The apparatus of claim 1, wherein said heat conduit comprises at least one chosen from the group consisting of a metal and a metal alloy.

11. The apparatus of claim 1, further comprising:

a battery mounted within said generally closed chamber, said battery being operatively associated with said video camera and said radio transmitter; and

a flash memory module mounted within said generally closed chamber, said flash memory module being operatively associated with said video camera, said flash memory module storing video data from said video camera.

12. The apparatus of claim 11, wherein said transmitter comprises a dual power radio transmitter, said dual power radio transmitter being operable in a high power transmission mode and a low power transmission mode.

13. Apparatus, comprising:

a generally closed chamber;

a heat source provided within said generally closed chamber;

a heat conduit having a first end and a second end, said heat conduit extending through an opening provided in said generally closed chamber so that the first end of said heat conduit is located interior to said generally closed chamber and so that the second end of said heat conduit is located exterior to said generally closed chamber, the first end of said heat conduit being mounted to said heat source so that heat from said heat source is transferred to said heat conduit; and

a heat sink mounted to the second end of said heat conduit, said heat sink dissipating heat from said heat source and conducted through said heat conduit.

14. The apparatus of claim 13, wherein said heat sink further comprises a plurality of fins.

15. The apparatus of claim 13, wherein said generally closed chamber comprises a water-tight chamber.

16. The apparatus of claim 13, wherein said heat source comprises a plurality of electronic devices.

17. The apparatus of claim 16, wherein said plurality of electronic devices comprises at least a radio transmitter and at least a video camera.

18. The apparatus of claim 13, wherein said heat conduit lacks a liquid heat transfer fluid.

19. A heat removal system for conducting heat from a heat source located within a generally closed chamber to a location outside the chamber, comprising:

a heat conduit having a first end and a second end, said heat conduit being sized to be received by an opening provided in the chamber, the first end of said heat conduit being mounted to the heat source contained within the chamber; and

a heat sink mounted to the second end of said heat conduit, the heat sink being located exterior to the chamber.
