## Abstract

An immersion cooling system includes a tank, a first condenser, an enclosure, a second condenser and a connecting pipe. The tank has a first space. The first space is configured to accommodate a cooling liquid for at least one electronic equipment to immerse therein. The first condenser is disposed inside the tank. The enclosure is disposed outside the tank. The enclosure forms a second space together with the tank. The second condenser is disposed in the second space. The connecting pipe includes a first end and a second end opposite to the first end. The first end is connected with the second condenser. The second end is communicated with the first space.

## Claims

### Claim 1

An immersion cooling system, comprising:
a tank having a first space configured to accommodate a cooling liquid for at least one electronic equipment to immerse therein;
a first condenser disposed inside the tank;
an enclosure disposed outside the tank and forming a second space together with the tank;
a second condenser disposed in the second space, the second condenser comprising:
a first main body configured to condense a first gas into a first liquid, the first main body having at least one first through hole;
a fan connected with the first main body and configured to absorb the first gas into the first main body through the first through hole;
a first input port communicated with the first main body and configured to allow a first water to flow into the first main body;
a first output port communicated with the first main body and configured to allow the first water to flow away from the first main body; and
at least one extension pipe connected with the first main body and communicated with the first through hole, the extension pipe having a plurality of second through holes arranged along an extending direction of the extension pipe; and
a connecting pipe comprising a first end and a second end opposite to the first end, the first end connecting with the first main body, the second end being communicated with the first space.

### Claim 2 (depends on 1)

The immersion cooling system of claim 1, wherein the second condenser and the first condenser are separated from each other.

### Claim 3 (depends on 1)

The immersion cooling system of claim 1, further comprising:
a first seal sealed between the enclosure and the tank.

### Claim 4 (depends on 1)

The immersion cooling system of claim 1, further comprising:
a check valve disposed on the connecting pipe.

### Claim 5 (depends on 1)

The immersion cooling system of claim 1, wherein the tank has an opening communicated between the first space and the second space, the immersion cooling system further comprises:
a cover pivotally connected with the tank and configured to open or close the opening.

### Claim 6 (depends on 5)

The immersion cooling system of claim 5, further comprising:
a second seal sealed between the cover and the tank.

### Claim 7 (depends on 1)

The immersion cooling system of claim 1, wherein a quantity of the first through hole and a quantity of the extension pipe are respectively plural.

### Claim 8 (depends on 1)

The immersion cooling system of claim 1, wherein the first condenser comprises a second main body, a second input port and a second output port, the second input port and the second output port are respectively communicated with the second main body, the second input port is configured to allow a second water to flow into the second main body, the second output port is configured to allow the second water to flow away from the second main body, and the second main body is configured to condense a second gas into a second liquid.

### Claim 9 (depends on 1)

The immersion cooling system of claim 1, wherein the second condenser is independently operational from the first condenser.

### Claim 10 (depends on 1)

The immersion cooling system of claim 1, wherein the first condenser is a water-cooling condenser, the second condenser is an air-cooling condenser separated from the water-cooling condenser.
