CLAIMS

1. A means for thermal cooling, comprising:

a heatsink means disposed within an environmentally-controlled region;

a mast means disposed outside of the environmentally-controlled region, the mast being coupled to an antenna circuitry means; and

one or more heat pipe means coupled to the heatsink means and the mast means, the one or more heat pipe means providing a heat transfer between the mast means and the heatsink means to thermally regulate a temperature of one or more portions of the antenna circuitry means.

2. The means for thermal cooling of Claim 1, wherein the one or more heat pipe means are coupled to the heatsink means and the mast means through a roof of a vehicle.

3. The means for thermal cooling of Claim 1, wherein the mast means includes a plurality of faces.

4. The means for thermal cooling of Claim 1, wherein the antenna circuitry means includes a plurality of antenna chip means, and wherein the mast means comprises a same number of the plurality of faces of the mast means as a number of the plurality of antenna chip means.

5. The means for thermal cooling of Claim 1, wherein each of the plurality of faces of the mast means is coupled to a respective one of the plurality of antenna chip means.

6. The means for thermal cooling of Claim 1, wherein the antenna circuitry means includes a number of active antenna chip means to facilitate communications for frequencies much above 6GHz, including a range of 24 to 86 GHz.

7. The means for thermal cooling of Claim 1, wherein the antenna circuitry means includes a number of active antenna chip means having an associated junction temperature, and wherein the heat transfer between the heatsink and the mast means regulates the associated junction temperature of the number of active antenna chip means.

8. The means for thermal cooling of Claim 1, wherein the mast means is comprised of a solid block of aluminum.

9. The means for thermal cooling of Claim 1, wherein each of the plurality of faces associated with the mast means forms an about 15 degree angle with respect to the vertical direction relative to the heatsink means.

10. The means for thermal cooling of Claim 1, wherein the one or more heat pipe means include at least two heat pipe means.

11. The means for thermal cooling of Claim 1, wherein the heatsink means includes one or more fan means to generate air flow through the heatsink means using air from the environmentally-controlled region.

12. The means for thermal cooling of one or more of Claims 1-11, wherein the antenna circuitry means includes a number of active antenna chip means having an associated junction temperature, and wherein the one or more fan means are turned on and off based upon the associated junction temperature associated with one or more of the number of active antenna chip means.

13. A means for thermal cooling, comprising:

an internal heatsink means disposed within a cab of a vehicle;

an external mast means disposed outside the cab of the vehicle, the external mast means having a plurality of faces, with each face from among the plurality of faces being coupled to a respective one of a plurality of active antenna chips means; and

one or more heat pipe means coupled to the internal heatsink means and to the external mast means, the one or more heat pipe means providing a heat transfer between the internal heatsink means and the external mast means to thermally regulate a temperature of one or more portions of the plurality of active antenna chip means.

14. The means for thermal cooling of Claim 13, wherein the one or more heat pipe means are coupled to the internal heatsink means and the external mast means through a roof of the vehicle.

15. The means for thermal cooling of Claim 13, wherein each of the plurality of faces associated with the external mast means forms an about 15 degree angle with respect to the vertical direction relative to the internal heatsink means, and wherein the external mast means comprises a same number of the plurality of faces of the external mast means as a number of the plurality of active antenna chip means.

16. The means for thermal cooling of Claim 13, wherein the plurality of active antenna chip means are configured to facilitate communications for frequencies much greater than 6 GHz, including a range of 24 to 86 GHz.

17. The means for thermal cooling of Claim 13, wherein the heat transfer between the internal heatsink means and the external mast means regulates a junction temperature of the plurality of active antenna chip means.

18. The means for thermal cooling of Claim 13, wherein the external mast means is comprised of a solid block of aluminum.

19. The means for thermal cooling of Claim 13, wherein the one or more heat pipe means include at least two heat pipe means.

20. The means for thermal cooling of one or more of Claims 13-19, wherein: the internal heatsink means includes one or more fan means to generate an air flow through the internal heatsink means using air within the cab of the vehicle, the plurality of active antenna chip means have an associated junction temperature, and the one or more fan means are turned on and off based upon the junction temperature associated with one or more of the plurality of active antenna chip means.
