Abstract

A system for thermal management and structural containment includes an enclosure, a heat source disposed within the enclosure; and a wick encompassing at least a portion of an outer surface of the heat source.

First claim

We claim:

1. A system for thermal management and structural containment, comprising:
an enclosure;
at least one battery disposed within the enclosure;
a battery surface wick encompassing at least a portion of an outer surface of the at least one battery;
an interior base wick disposed on and in thermal communication with an inner surface of a first wall of the enclosure, wherein the interior base wick is in capillary force communication with the battery surface wick;
and
a working fluid in capillary force communication with the battery surface wick.

2. The system of claim 1 , further comprising:
an interior wick structure disposed on and in thermal communication with an interior surface of a second wall of the enclosure, wherein the interior wick structure is in capillary force communication with the interior base wick.

3. The system of claim 2 , further comprising:
a heater disposed on an exterior side of a second wall, the heater disposed in complementary opposition to the interior wick structure.

4. The system of claim 1 , wherein the at least one battery comprises a first plurality of batteries disposed within the enclosure,
wherein a portion of an outer surface of each battery of the first plurality of batteries is encompassed by a battery surface wick, and
wherein the battery surface wick of each battery of the first plurality of batteries is in capillary force communication with the interior base wick.

5. The system of claim 4 , wherein the first plurality of batteries is stacked in a mono-block configuration.

6. The system of claim 5 , wherein the first plurality of batteries stacked in a mono-block configuration are stacked on the interior base wick.

7. The system of claim 6 , further comprising:
a second plurality of batteries stacked in a mono-block configuration on the interior base wick, wherein each battery of the second plurality of batteries comprises an outer surface encompassed by a battery surface wick, and
wherein the battery surface wick of each battery of the second plurality of batteries is in capillary force communication with the interior base wick.

8. The system of claim 7 , further comprising:
an interior frame structure between the first plurality of batteries and the second plurality of batteries.

9. The system of claim 1 , wherein the working fluid is a dielectric liquid.

10. The system of claim 1 , wherein the enclosure is a vapor-tight or substantially vapor-tight enclosure.

11. The system of claim 1 , further comprising an operational flow of the working fluid, wherein the operation flow is defined by:
evaporation of a portion of the working fluid from the battery surface wick upon receiving heat from the at least one battery;
condensation of at least a portion of the evaporated portion of the working fluid on the interior base wick; and
fluid transportation by a capillary force of the condensed evaporated portion of the working fluid from the interior base wick to the battery surface wick.

12. The system of claim 2 , wherein any one or more of the battery surface wick, the interior wick structure, and the interior base wick comprise one of ceramic, cellulose, glass, graphite, or polymer fibers.

13. The system of claim 2 , wherein any one or more of the battery surface wick, the interior wick structure, and the interior base wick comprise a fabric of non-woven, woven, knitted, or braided fibers.

14. The system of claim 2 , wherein any one or more of the battery surface wick, the interior wick structure, and the interior base wick comprise a multi scale wick structure.

15. The system of claim 14 , wherein the at least one battery comprises a first terminal surface and a second terminal surface, and wherein the second terminal surface is partially covered by a bottom wick.

16. The system of claim 15 , wherein the interior wick structure of the second wall is in capillary force communication with the battery surface wick via the bottom wick.

17. The system of claim 14 , wherein the second wall is a base wall or a side wall of the enclosure.

18. The system of claim 1 , wherein the battery surface wick is a multi scale wick.

19. The system of claim 14 , wherein the multi scale wick comprises a plurality of wick layers and wherein each adjacent wick layer comprises a different pore size distribution.

20. The system of claim 4 , further comprising a secondary wick in capillary force communication with at least one battery surface wick of the first plurality of batteries and extending along at least a portion of an outer surface of the at least one battery surface wick of the first plurality of batteries.

21. The system of claim 2 , further comprising an operational flow of the working fluid, wherein the operation flow is defined by:
evaporation of a portion of the working fluid from the battery surface wick upon receiving heat from the at least one battery;
condensation of a portion of the evaporated portion of the working fluid on the interior wick structure; and
fluid transportation by a capillary force of the condensed evaporated portion of the working fluid from the interior wick structure to the battery surface wick via the interior base wick.

22. The system of claim 3 , further comprising an operational flow of the working fluid, wherein the operation flow is defined by:
evaporation of a portion of the working fluid from the interior wick structure upon receiving heat from the heater; and
condensation of a portion of the evaporated portion of the working fluid on the battery surface wick.
