Rack-mountable immersion cooling system

1. An immersion cooling system, comprising:

a plurality of spaced-apart cooling plates defining a plurality of subvolumes therebetween, the cooling plates at least partially immersed in a first liquid coolant, so that the first liquid coolant at least partially fills each subvolume;

a second liquid coolant flowing through at least a portion of each cooling plate; and

at least one electronic device at least partially immersed in the first liquid coolant within each subvolume;

wherein the immersion cooling system is configured to be mounted on slides in a standard server rack.

2. The immersion cooling system of claim 1 , wherein the first liquid coolant is a dielectric fluid.

3. The immersion cooling system of claim 1 , wherein the second liquid coolant is selected from the group consisting of water, ethylene glycol and water solution, diethylene glycol and water solution, and propylene glycol and water solution.

4. The immersion cooling system of claim 1 , wherein at least one subvolume of the plurality of subvolumes is in fluidic communication with at least one other subvolume of the plurality of subvolumes.

5. The immersion cooling system of claim 1 , wherein the at least one electronic device is an electronic server.

6. The immersion cooling system of claim 5 , further comprising a heat exchanger in fluidic communication with the cooling plate.

7. The immersion cooling system of claim 5 , wherein the first liquid coolant is a dielectric fluid.

8. The immersion cooling system of claim 5 , wherein the second liquid coolant is selected from the group consisting of water, ethylene glycol and water solution, diethylene glycol and water solution, and propylene glycol and water solution.

9. The immersion cooling system of claim 5 , wherein the at least one wall of the open interior volume is a wall dividing the open interior volume into subvolumes.

10. An immersion cooling system, comprising:

a tank defining an open interior volume and comprising a cooling plate forming at least one wall of the open interior volume;

a first liquid coolant at least partially filling the open interior volume;

a second liquid coolant flowing through at least a portion of the cooling plate; and

at least one electronic device at least partially immersed in the first liquid coolant within the open interior volume;

wherein the immersion cooling system is configured to be mounted on slides in a standard server rack.

11. The immersion cooling system of claim 10 , wherein the at least one electronic device is an electronic server.

12. A method of cooling electronic devices, comprising:

disposing a plurality of cooling plates so as to define a plurality of subvolumes;

at least partially filling each subvolume with a first coolant liquid, such that each of the plurality of cooling plates is at least partially immersed in the first coolant liquid;

providing a second coolant fluid disposed within the cooling plate;

disposing at least one electronic device in at least one subvolume such that it is at least partially immersed in the first coolant fluid; and

mounting the plurality of cooling plates including the plurality of subvolumes and electronic devices on slides in a standard server rack.

13. The method of claim 12 , further comprising:

creating a fluidic circuit comprising a heat exchanger and the plurality of cooling plates; and

circulating the second coolant fluid through the fluidic circuit.

14. The method of claim 12 , wherein the first liquid coolant is a dielectric fluid.

15. The method of claim 12 , wherein the second liquid coolant is selected from the group consisting of water, ethylene glycol and water solution, diethylene glycol and water solution, and propylene glycol and water solution.

16. The method of claim 12 , wherein the at least one electronic device is an electronic server.
