Abstract

The subject disclosure is directed towards a datacenter or partial datacenter (e.g., a datacenter module) contained in a sealed container. The container may be filled with a cooling fluid, such as a dielectric fluid, to help cool the datacenter components. The container and its internal datacenter or datacenter portion may be submerged in water, in which event the fluid also helps to equalize the external water pressure.

First claim

What is claimed is:

1. A system comprising:
a datacenter or partial datacenter immersed in a cooling fluid, the data center or partial datacenter comprising:
a sealed container that surrounds and seals the cooling fluid and the datacenter or partial datacenter, the sealed container configured for submersion in submarine conditions, including having chamfered edges; and
a heat transfer subsystem configured to cool the cooling fluid and the datacenter or partial datacenter and transfer heat away from the datacenter or partial datacenter to surrounding water in the submarine conditions, including to circulate a dielectric fluid throughout the sealed container via a sealed circulation pipe passing through the sealed container and to transfer heat from the circulated dielectric fluid to the surrounding water via a heat transfer mechanism.

2. The system of claim 1 wherein the cooling fluid is a dielectric fluid, and wherein components of the datacenter are immersed in the dielectric fluid.

3. The system of claim 1 wherein the container incorporates or is coupled to at least one pump to circulate the cooling fluid.

4. The system of claim 1 wherein the sealed container is submerged in water, and wherein the heat transfer subsystem is configured to cool the cooling fluid and the datacenter or partial datacenter by transferring at least some heat from the sealed container to the water.

5. The system of claim 4 wherein the container is sufficiently filled with the cooling fluid to reduce or equalize a pressure difference between external water pressure and at least part of the internal container pressure.

6. The system of claim 4 wherein the heat transfer subsystem comprises heat pipe technology that provides conductive transfer of heat from the cooling fluid within the sealed container to the water surrounding the sealed container.

7. A system comprising:
a datacenter or partial datacenter enclosed in a sealed container comprising chamfered edges and submerged in water in submarine conditions, the sealed container further comprising:
a heat transfer subsystem that transfers heat away from the sealed container into the water, including by circulating a cooling fluid throughout the sealed container to reduce or equalize a pressure difference between external water pressure external to the sealed container and at least part of an internal pressure of the sealed container and to transfer the heat away from the sealed container into the water.

8. The system of claim 7 wherein the heat transfer subsystem comprises a pump that circulates the cooling fluid within the sealed container.

9. The system of 7 wherein at least part of the heat transfer subsystem uses a surface of the sealed container to transfer at least some heat to the water in submarine conditions outside the sealed container.

10. The system of 7 wherein the heat transfer subsystem comprises a hydronic loop that provides conductive transfer of heat from the cooling fluid within the sealed container to the water surrounding the sealed container.

11. The system of 7 wherein at least part of the heat transfer subsystem uses at least one heat pipe to cool the datacenter or partial datacenter and the cooling fluid.
