Abstract

A thermal control system for directing fluids between a reservoir and a rotatable platform. The system comprises a rotatable platform having an inlet port for receiving a cooling fluid; a reservoir adjacent the platform houses the cooling fluid for transport to the rotatable platform; and a non rotary jointed conduit having a first end immersed in the cooling fluid of the reservoir provides a fluid path for the cooling fluid to the rotatable platform.

Claims

1. A thermal control system comprising:

a rotatable platform having an inlet port for receiving a cooling fluid;

a reservoir for housing said cooling fluid for transport to said rotatable platform; and

a non rotary jointed conduit having a first end immersed in said cooling fluid of said reservoir for providing a fluid path for said cooling fluid to said rotatable platform, said reservoir aligned with said platform whereby said non rotary jointed conduit moves through said fluid during operation of said rotatable platform.

2. The system of claim 1, further comprising a cooling unit coupled to said reservoir for providing cooling fluid thereto.

3. The system of claim 2, wherein said cooling unit comprises a heat exchanger fluidly coupled to said reservoir.

4. The system of claim 1, further comprising:

a second reservoir for receiving heated fluid; and

at least one cooling unit coupled to said first and second reservoirs and operative for receiving the heated fluid from the second reservoir and providing cooling fluid to said first reservoir.

5. The system of claim 4, wherein said at least one cooling unit comprises a plurality of heat exchangers.

6. The system of claim 1, wherein said non rotary jointed conduit comprises a tube.

7. The system of claim 1, wherein said non rotary jointed conduit comprises a flexible material.

8. The system of claim 1, wherein said non rotary jointed conduit comprises a rigid material.

9. The system of claim 1, wherein the reservoir is stationary relative to a fixed position.

10. The system of claim 1, wherein the reservoir rotates with the rotatable platform.

11. The system of claim 2, wherein said cooling unit is stationary relative to the reservoir.

12. The system of claim 4, wherein the first and second reservoirs are concentric.

13. The system of claim 4, wherein the first and second reservoirs are disposed below the rotatable platform to thereby enable a gravity feed of the heated fluid from the outlet port to the second reservoir.

14. A method for cooling a rotatable platform having an inlet port for receiving a cooling fluid, said method comprising:

providing a reservoir for housing cooling fluid;

aligning said reservoir with said inlet port of said platform; and

providing said cooling fluid housed in said reservoir via a non rotary jointed conduit into said inlet port of said rotatable platform, whereby said non rotary jointed conduit moves through said fluid during operation of said rotatable platform.

15. The method of claim 14, wherein the step of providing said cooling fluid housed in said reservoir via a non rotary jointed conduit further comprises pumping said cooling fluid through said non rotary jointed conduit.

16. A thermal control system for exchanging fluids between a rotatable platform and a reservoir, said system comprising:

a rotatable platform having an inlet port for receiving a cooled fluid and an outlet port for providing a heated fluid;

a reservoir comprising a first vessel for receiving the heated fluid from the outlet port of the rotatable platform, and a second vessel for housing cooled fluid for transport to the inlet port of the rotatable platform via a non rotary jointed conduit, said conduit having an end immersed in said cooled fluid in said second vessel; and

a heat exchanger coupled to the first and second vessels, said heat exchanger operative for receiving the heated fluid from the first vessel, and for providing cooled fluid to the second vessel for transport via said non rotary jointed conduit to the rotatable platform.

17. The system of claim 16, further comprising a second non rotary jointed conduit having a first end coupled to the output port of the rotatable platform for providing a fluid path for said heated fluid to said first vessel.

18. The system of claim 16, wherein the reservoir is stationary relative to a fixed position.

19. The system of claim 16, wherein the reservoir rotates with the rotatable platform.

20. The system of claim 16, further comprising a plurality of heat exchangers fluidly coupled to the first and second vessels.

21. The system of claim 16, wherein said heat exchanger is stationary relative to the reservoir.

22. The system of claim 16, wherein the first vessel is circular, oval or elliptical shaped, and said second vessel is annular shaped.

23. The system of claim 16, wherein the reservoir is disposed below the rotatable platform to thereby enable a gravity feed of the heated fluid from the outlet port to the first vessel.

24. The system of claim 16, wherein the reservoir is disposed below the rotatable platform such that the outlet port is vertically aligned with the first vessel.

25. The system of claim 16, wherein the heat exchanger includes a pump for pumping the cooled fluid through the second vessel of the reservoir to the platform.

26. An antenna system comprising:

an antenna array mounted on a first wheel, the first wheel having a circumferential portion adapted to engage at least one path disposed on a platform for revolving the radar array about the platform;

an axle coupled to the first wheel; and

a thermal control system for providing cooling fluid to the antenna array, said thermal control system comprising;

a first vessel for housing said cooling fluid for transport to said antenna array; and

a non rotary jointed conduit having a first end immersed in said cooling fluid of said first vessel and a second end coupled to said antenna array for providing a fluid path to said array for said cooling fluid.

27. The system of claim 26, wherein said fluid path is carried by said axle.

28. The system of claim 27, wherein said fluid path is formed within an interior of said axle.

29. The system of claim 26, wherein said antenna array comprises an outlet for exhausting said fluid transported to said array via said fluid path.

30. The system of claim 26, further comprising a guard disposed a predetermined distance from said outlet and adapted to re-direct portions of the exhausted fluid incident on said guard to a second vessel.

31. The system of claim 30, wherein the second vessel is separated from the outlet of the antenna array by an air gap.

32. The system of claim 27, wherein said antenna array comprises an outlet for exhausting said fluid transported to said array, and wherein a second fluid path extending from said outlet is carried by said axle for returning said exhausted fluid from said antenna array to said first vessel.

33. The system of claim 26, further comprising a heat exchanger coupled to said first and second vessels for receiving the exhausted fluid from the second vessel and providing cooling fluid to said first vessel.

34. An antenna system comprising:
