Abstract

An immersion cooling system is provided and includes a storage tank, an adapter frame, and an electronic device. The storage tank includes an accommodating tank and a sealing cover for sealing the opening of the accommodating tank. The adapter frame includes a first wire channel attached to the side of the adapter frame, and is disposed in the accommodating tank in a vertical direction. The electronic device includes at least one power wire, and is inserted into the adapter frame along the above direction. The side of the electronic device is attached to the side of the first wire channel. A second wire channel is formed between the bottoms of the electronic device and the adapter frame, and the first and second wire channels communicate with each other. The power wire is connected to the circuit of the external power apparatus along the first and second wire channels.

Claims (30)

1 . An immersion cooling system, comprising:

a storage tank comprising a sealing cover and an accommodating tank, and the sealing cover is configured to seal an opening of the accommodating tank;

an adapter frame comprising a first wire channel, wherein the first wire channel is attached to one side of the adapter frame, and the adapter frame is disposed in the accommodating tank in a direction perpendicular to a bottom of the accommodating tank; and

an electronic device comprising at least one power wire, wherein the electronic device is inserted into the adapter frame along the direction, and one side of the electronic device is attached to one side of the first wire channel,

wherein a distance is formed between a bottom of the electronic device and a bottom of the adapter frame to form a second wire channel, and the first wire channel and the second wire channel communicate with each other,

wherein the at least one power wire is electrically connected to an external electric apparatus from the bottom of the electronic device along the first wire channel and the second wire channel.

2 . The immersion cooling system as claimed in claim 1 , wherein the adapter frame further comprises a positioning portion adjacent to the first wire channel, and the positioning portion is matched with a bracket of the accommodating tank.

3 . The immersion cooling system as claimed in claim 2 , wherein the adapter frame further comprises an extension portion connected to a top surface of the positioning portion and extending in a direction parallel to the top surface.

4 . The immersion cooling system as claimed in claim 3 , wherein the adapter frame further comprises a fixing member suitable for penetrating through the extension portion and the bracket of the accommodating tank, so that the adapter frame is affixed to the accommodating tank.

5 . The immersion cooling system as claimed in claim 3 , wherein the extension portion has at least one hole configured to be aligned with one hole on the bracket.

6 . The immersion cooling system as claimed in claim 2 , wherein the positioning portion protrudes from an outlet end of the first wire channel.

7 . The immersion cooling system as claimed in claim 2 , wherein the positioning portion has a plurality of openings, and the plurality of openings of the positioning portion communicate with each other.

8 . The immersion cooling system as claimed in claim 1 , wherein a length of the one side of the electronic device is equal to a length of the one side of the first wire channel.

9 . The immersion cooling system as claimed in claim 1 , wherein the adapter frame further comprises a back plate connected to the bottom of the adapter frame and the one side of the first wire channel.

10 . The immersion cooling system as claimed in claim 1 , wherein the accommodating tank further comprises a positioning member disposed on a sidewall of the accommodating tank and configured to abut against the adapter frame.

11 . The immersion cooling system as claimed in claim 1 , further comprising a hanging ear disposed beside the first wire channel, and a positioning portion of the adapter frame is disposed below the hanging ear.

12 . The immersion cooling system as claimed in claim 11 , wherein the hanging ear has a recess configured to correspond to a hook-shaped structure of a hanging apparatus.

13 . An immersion cooling system, comprising:

a storage tank comprising a sealing cover and an accommodating tank, and the sealing cover is configured to seal an opening of the accommodating tank;

an adapter frame comprising a first wire channel, wherein the first wire channel is attached to one side of the adapter frame, and the adapter frame is disposed in the accommodating tank in a direction perpendicular to a bottom of the accommodating tank; and

an electronic device inserted into the adapter frame in the direction,

wherein the adapter frame comprises a positioning portion adjacent to the first wire channel, the positioning portion is matched with a bracket of the accommodating tank, and the positioning portion has a plurality of openings configured for a hanging apparatus connected to the adapter frame, the adapter frame further comprises:

an extension portion connected to a top surface of the positioning portion and extending in a direction that is parallel to the top surface; and

a plurality of protruding portions disposed on the extension portion and protruding toward a direction that is away from the electronic device.

14 . The immersion cooling system as claimed in claim 13 , wherein the plurality of openings of the positioning portion each have a rectangular outline.

15 . The immersion cooling system as claimed in claim 13 , wherein the plurality of openings of the positioning portion are located on a top surface of the positioning portion and a sidewall connected to the top surface.

16 . The immersion cooling system as claimed in claim 13 , wherein a bottom of the electronic device is level with a hub end of the first wire channel in a direction parallel to the bottom of the accommodating tank.

17 . The immersion cooling system as claimed in claim 13 , wherein the plurality of openings of the positioning portion communicate with each other.

18 . The immersion cooling system as claimed in claim 13 , wherein the plurality of protruding portions are located on opposite sides of the extension portion.

19 . The immersion cooling system as claimed in claim 13 , wherein the plurality of openings of the positioning portion are located over the first wire channel.
