Abstract

A cellular communication antenna has a base with a length that exceeds its width and an inside surface with internal mounts for a plurality of electrical components that generate heat when in operation. A top encapsulates the electrical components and incorporates a radome. A plurality of fins are mounted on the outside surface of the base. They may be non-parallel with the length of the base. They may all be substantially the same length. They are further constructed and arranged to be in thermal communication with the electrical components such that heat generated by the electrical components is dissipated by the fins. Each fin may be in thermally conductive communication with more than one electrical component.

Claims

1. A cellular communication antenna comprising:

a base having a length and a width and having an inside surface and an outside surface;

said base having mounts for a plurality of electrical components, said electrical components generating heat when in operation;

a top encapsulating said electrical components, said top incorporating a radome;

a plurality of fins mounted on said outside surface of said base, said fins being non-parallel with said length of said base and at an angle between about 40 degrees and about 75 degrees from horizontal; and

said fins being in thermal communication with said electrical components such that heat generated by said electrical components is dissipated by said fins.

2. The antenna of claim 1 wherein each of said fins is substantially the same length.

3. The antenna of claim 1 wherein said fins define spaces therebetween, each of said spaces opening on a side of said antenna such that unheated air may enter said spaces from the side.

4. The antenna of claim 1 wherein said fins define spaces, each of said spaces opening on a side of said antenna such that heated air may exit said spaces to the side.

5. The antenna of claim 1 wherein said base is a generally planar rectangle.

6. The antenna of claim 1 wherein said electrical components are mounted on modules;

each of said fins being deployed to be in thermal communication with at least two of said modules.

7. The antenna of claim 6 wherein said fins are deployed in groups, each group being in thermal communication with at least two of said electrical components.

8. The antenna of claim 1 wherein said fins are deployed in groups, each group being in thermal communication with at least two of said electrical components.

9. The antenna of claim 8 wherein said fins define spaces therebetween, each of said spaces opening on a side of said antenna such that unheated air may enter said spaces from the side.

10. The antenna of claim 8 wherein said fins define spaces, each of said spaces opening on a side of said antenna such that heated air may exit said spaces to the side.

11. The antenna of claim 8 wherein each of said fins is substantially the same length.

12. The antenna of claim 1 further comprising:

said fins being arranged in groups; and

said groups being separated by gaps.

13. The antenna of claim 12 wherein said fins define spaces therebetween, each of said spaces opening on a side of said antenna such that unheated air may enter said spaces from the side.

14. The antenna of claim 12 wherein said fins define spaces, each of said spaces opening on a side of said antenna such that heated air may exit said spaces to the side.

15. The antenna of claim 12 wherein said electrical components are mounted on modules;

each of said groups of fins being deployed to be in thermal communication with at least two of said modules.

16. The antenna of claim 12 further comprising said groups being in thermal communication with at least two of said electrical components.

17. The antenna of claim 12 further comprising a baffle disposed in said gap.

18. The antenna of claim 17 further comprising a pair of said baffles forming a chevron.

19. The antenna of claim 1 further comprising a central vertical channel.
