Abstract

Systems and methods for a dry power supply for immersion-cooled Information Handling Systems (IHSs) are described. In some embodiments, an IHS may include: a chassis configured to be at least partially disposed under a surface of a dielectric liquid coolant, where the chassis includes one or more components configured to be cooled by the dielectric liquid coolant during operation of the IHS; and a power supply coupled to the chassis and configured to provide power to the one or more components via an adaptor configured to maintain the power supply above the surface of the dielectric liquid coolant during operation of the IHS, where the power supply comprises a fan configured to blow air.

Claims

1. An Information Handling System (IHS), comprising:

a chassis configured to be at least partially disposed under a surface of a dielectric liquid coolant, wherein the chassis includes one or more components configured to be cooled by the dielectric liquid coolant during operation of the IHS; and

a power supply coupled to the chassis and configured to provide power to the one or more components via an adaptor configured to maintain the power supply above the surface of the dielectric liquid coolant during operation of the IHS, wherein the power supply comprises a fan configured to blow air.

2. The IHS of claim 1, wherein the IHS is a server.

3. The IHS of claim 1, wherein the chassis is unsealed against the dielectric liquid coolant.

4. The IHS of claim 1, wherein the dielectric liquid coolant comprises oil.

5. The IHS of claim 1, wherein the dielectric liquid coolant is held inside a tank, the tank comprises a top and a rack, and the chassis is mountable on the rack such that the IHS is removable from the tank through the top while another IHS remains in operation at least partially disposed under the surface of the dielectric liquid coolant.

6. The IHS of claim 1, wherein the one or more components comprises a processor.

7. The IHS of claim 1, wherein the power supply is an off-the-shelf power supply.

8. The IHS of claim 1, wherein the adaptor includes a first electrical connector configured to be coupled to the IHS and a second electrical connector configured to be coupled to the power supply.

9. The IHS of claim 8, wherein the first and second electrical connectors are coupled to each other via a printed circuit board (PCB) extender, and wherein the second electrical connector is disposed on an opposite side of the PCB extender from the first electrical connector.

10. The IHS of claim 9, wherein the adaptor includes a bay coupled to the PCB extender and configured to receive the power supply, the bay configured to allow a power supply connector to be coupled to the second electrical connector.

11. The IHS of claim 10, wherein the bay is configured to hold the power supply above the surface of the dielectric liquid coolant while a portion of the PCB extender remains under the surface of the dielectric liquid coolant.

12. The IHS of claim 11, wherein the bay includes a handle portion configured to allow a user to slide the power supply in and out of the bay coupling and decoupling the power supply to and from the IHS, respectively.

13. A power supply adaptor, comprising:

a printed circuit board (PCB) extender having a first electrical connector configured to be coupled to the IHS and a second electrical connector configured to be coupled to a power supply; and

a bay coupled to the PCB extender and configured to receive the power supply, the bay configured to allow the power supply to be coupled to the second electrical connector.

14. The power supply adaptor of claim 13, wherein the second electrical connector is disposed on an opposite side of the PCB extender from the first electrical connector.

15. The power supply adaptor of claim 13, wherein the bay is configured to hold the power supply above a surface of a dielectric liquid coolant while a portion of the PCB extender remains under the surface of the dielectric liquid coolant.

16. The power supply adaptor of claim 15, wherein the power supply provides power to an Information Handling System (IHS) having a chassis that is being cooled by the dielectric liquid coolant within a tank.

17. A power supply assembly, comprising:

a power supply configured to provide power to an Information Handling System (IHS) having a chassis cooled by a dielectric liquid coolant within a tank; and

a printed circuit board (PCB) extender having a first electrical connector configured to the coupled to the IHS and a second electrical connector configured to be coupled to the power supply while keeping the power supply above a surface of the dielectric liquid coolant when a portion of the PCB extender remains under the surface of the dielectric liquid coolant.

18. The power supply assembly of claim 17, wherein the second electrical connector is disposed on an opposite side of the PCB extender from the first electrical connector.

19. The power supply assembly of claim 17, further comprising a bay coupled to the PCB extender and configured to receive the power supply, the bay configured to allow the power supply to be coupled to the second electrical connector.

20. The power supply assembly of claim 19, wherein the bay includes a handle portion configured to allow a user to slide the power supply in and out of the bay coupling and decoupling the power supply to and from the IHS, respectively.
