Abstract

Methods, systems, and devices are provided for cooling a heat source. One apparatus embodiment includes a housing, a fluid conduit, a pump within the housing and in communication with the fluid conduit for conveying fluid through the fluid conduit, and a turbine in communication with the fluid conduit to be driven by the fluid as it passes through the fluid conduit.

Claims

1. An apparatus, comprising:

a housing;

a fluid conduit;

a pump within the housing and in communication with the fluid conduit for conveying fluid through the fluid conduit; and

a turbine in communication with the fluid conduit to be driven by the fluid as it passes through the fluid conduit and attached to a shaft that provides rotation to a fan blade to move air away from the housing.

2. The apparatus of claim 1, wherein the housing includes a heat source and wherein heat from the heat source can be absorbed by the fluid in the fluid conduit.

3. The apparatus of claim 2, wherein the heat source includes a number of computer processors.

4. The apparatus of claim 2, wherein the heat source includes a number of circuit boards.

5. The apparatus of claim 1, wherein the turbine is positioned outside the housing.

6. The apparatus of claim 1, wherein the turbine impeller is connected to a drive shaft that is driven by communication of the turbine impeller with the fluid passing through the fluid conduit.

7. The apparatus of claim 6, wherein the drive shaft drives a fan to dissipate heat from the fluid in the fluid conduit.

8. The apparatus of claim 1, wherein the housing is nuclear, biological, and chemical restrictive.

9. The apparatus of claim 1, wherein the apparatus further includes a heat exchanger for removing heat from the fluid within the fluid conduit.

10. A fluid handling system, comprising:

a housing;

a fluid conduit;

a pump within the housing and in communication with the fluid conduit for conveying fluid through the fluid conduit;

a heat exchanger for removing heat from the fluid within the fluid conduit; and

a turbine in communication with the fluid conduit to be driven by the fluid as it passes through the fluid conduit and attached to a shaft that provides rotation to a fan blade to move air away from the housing.

11. The system of claim 10, the heat exchanger is positioned outside the housing.

12. The system of claim 10, wherein the heat exchanger includes a number of fins for dissipating heat.

13. The system of claim 10, wherein the turbine is positioned outside the housing.

14. The system of claim 10, wherein the fan blade is positioned to move air across the heat exchanger.

15. The system of claim 10, wherein the system further includes an electrical heat source positioned within the housings, wherein the pump is an electrical pump, and wherein the housing is impervious to a fluid.

16. The system of claim 10, wherein components of the system positioned outside the housing can be cleaned with a fluid.

17. The system of claim 10, wherein components of the system positioned outside the housing are non-electrical.

18. A method for cooling a heat source, comprising:

pumping a fluid through an interior periphery of a housing;

absorbing heat from a heat source into the fluid flowing through the housing;

removing the heat from the fluid to an exterior of the housing with a heat exchanger; and

directing the fluid through a turbine connected to a shaft of a fan to turn the shaft of the fan positioned outside the housing to direct heat away from the housing.

19. The method of claim 18, wherein turning a shaft of a fan includes moving a turbine impeller by directing the fluid through the turbine impeller connected to the shaft of the fan.

20. The method of claim 18, wherein removing the heat includes directing the fluid into a heat exchanger.

21. The method of claim 18, wherein absorbing heat from a heat source into a fluid flowing through a housing includes absorbing heat from a heat source within a housing.

22. The method of claim 18, wherein absorbing heat from a heat source includes absorbing heat from an electrical component.
