Abstract

A liquid cooling leak detection system includes a sensor cable, a leak sensor cable carrier, and multiple cable carriers. The sensor cable indicates a detected leak based on the sensor cable being in contact with a liquid. The leak sensor cable carrier is in physical communication with the sensor cable. The cable carriers are in physical communication with the sensor cable and with the leak sensor cable carrier. Each of the cable carriers includes a support structure and an absorbent material. The absorbent material is in physical communication with the support structure and with the sensor cable. The absorbent material transfers the liquid from a portion of the absorbent material to the sensor cable.

Claims (42)

1 . A liquid cooling leak detection system comprising:

a sensor cable to indicate a detected leak based on the sensor cable being in contact with a liquid;

a leak sensor cable carrier in physical communication with the sensor cable, the leak sensor cable carrier includes first and second tabs; and

a plurality of cable carriers in physical communication with the sensor cable and with the leak sensor cable carrier, each of the cable carriers including:

a support structure in physical communication with the first and second tabs of the leak sensor cable carrier, wherein the first and second tabs hold the support structure in physical communication with the leak sensor cable carrier when the support structure is at an engaged position, at a disengaged position, and

when the support structure transitions between the engaged position and the disengaged position; and

an absorbent material in physical communication with the support structure and with the sensor cable, the absorbent material to transfer the liquid from a portion of the absorbent material to the sensor cable.

2 . The liquid cooling leak detection system of claim 1 , further comprising: a location to receive a corresponding cold plate and a corresponding graphics processing unit.

3 . The liquid cooling leak detection system of claim 2 , wherein a first cable carrier of the plurality of cable carriers is placed on a first edge of the location, and a second cable carrier of the plurality of cable carriers is placed on a second edge of the location.

4 . The liquid cooling leak detection system of claim 3 , wherein the first and second edges of the location are opposite sides of the location.

5 . The liquid cooling leak detection system of claim 1 , wherein the support structure includes: a back, a base, a bump, and a bending tab, the bump and bending tab extend from the base.

6 . The liquid cooling leak detection system of claim 5 , wherein the leak sensor cable carrier includes an edge, and the bump is in physical communication with the edge when the support structure is in the engaged position.

7 . The liquid cooling leak detection system of claim 6 , wherein the bending tab is in physical communication with the edge when the support structure is in the disengaged position.

8 . An information handling system comprising:

a cooling pipe;

a cold plate;

a coupler to connect the cold plate and the cooling pipe;

a cold plate fitting in physical communication with the coupler; and

a liquid cooling leak detection system including:

a sensor cable to indicate a detected leak when the sensor cable is in contact with a liquid;

a leak sensor cable carrier in physical communication with the sensor cable, the leak sensor cable carrier includes first and second tabs; and

a plurality of cable carriers in physical communication with the sensor cable and with the leak sensor cable carrier, a first cable carrier of the cable carriers including:

a support structure in physical communication with the first and second tabs of the leak sensor cable carrier, wherein the first and second tabs hold the support structure in physical communication with the leak sensor cable carrier when the support structure is at an engaged position, at a disengaged position, and when the support structure transitions between the engaged position and the disengaged position; and

an absorbent material in physical communication with the support structure and with the sensor cable, the absorbent material located under the cold plate fitting when the support structure is in an engaged position, the

absorbent material to transfer the liquid from a portion of the absorbent material to the sensor cable.

9 . The information handling system of claim 8 , wherein liquid cooling leak detection system further includes a location to receive the cold plate and a corresponding graphics processing unit.

10 . The information handling system of claim 9 , wherein the first cable carrier is placed on a first edge of the location, and a second cable carrier of the cable carriers is placed on a second edge of the location.

11 . The information handling system of claim 10 , wherein the first and second edges of the location are opposite sides of the location.

12 . The information handling system of claim 8 , wherein the support structure includes: a back, a base, a bump, and a bending tab, the bump and bending tab extend from the base.

13 . The information handling system of claim 12 , wherein the leak sensor cable carrier includes an edge, and the bump is in physical communication with the edge when the support structure is in the engaged position.

14 . The information handling system of claim 13 , wherein the bending tab is in physical communication with the edge when the support structure is in the disengaged position.

15 . The information handling system of claim 12 , wherein the absorbent material is past the cold plate fitting when the support structure is in the disengaged position.

16 . A liquid cooling leak detection system comprising:

a sensor cable to indicate a detected leak when in contact with a liquid;

a leak sensor cable carrier in physical communication with the sensor cable, the leak sensor cable carrier including first and second tabs; and

a plurality of cable carriers in physical communication with the sensor cable and with the leak sensor cable carrier, each of the cable carriers including:

a support structure in physical communication with the first and second tabs of the leak sensor cable carrier, wherein the first and second tabs hold the support structure in physical communication with the leak sensor cable carrier when the support structure is at an engaged position, at a disengaged position, and

when the support structure transitions between the engaged position and the disengaged position, the support structure includes a back, a base, a bump, and a bending tab, the bump and bending tab extending from the base,

wherein the support structure is held in physical communication with the leak sensor cable carrier via the first and second tabs; and

an absorbent material in physical communication with the support structure and with the sensor cable, the absorbent material to transfer the liquid from a portion of the absorbent material to the sensor cable.

17 . The liquid cooling leak detection system of claim 16 , wherein the leak sensor cable carrier includes an edge, and the bump is in physical communication with the edge when the support structure is in the engaged position.

18 . The liquid cooling leak detection system of claim 17 , wherein the bending tab is in physical communication with the edge when the support structure is in the disengaged position.
