## Abstract

Systems and methods are provided for a leak sensor drip tray. In some embodiments, an Information Handling System (IHS) may include: a component; a cold plate disposed above the component; a leak sensor board disposed above the cold plate; and a drip tray disposed above the leak sensor, wherein the drip tray is configured to capture a fluid leak from a fitting coupled to the cold plate.

## Claims

### Claim 1

An Information Handling System (IHS), comprising:
a component;
a cold plate disposed above the component;
a leak sensor board disposed above the cold plate; and
a drip tray disposed above the leak sensor board, wherein the drip tray is configured to capture a fluid leak from a fitting coupled to the cold plate, wherein the leak sensor board comprises a microstrip differential trace moisture sensor, and wherein the drip tray has a concave shape and comprises:
at least one hole configured to receive the fitting;
at least one drain configured to guide the fluid leak from the fitting toward the microstrip differential trace moisture sensor; and
at least another drain configured to guide another fluid leak from another fitting toward another microstrip differential trace moisture sensor.

### Claim 2 (depends on 1)

The IHS of claim 1, wherein the drip tray further comprises a lateral wall configured to guide air flow from a fan into a dual in-line memory module (DIMM) area.

### Claim 3

A drip tray, comprising:
a concave surface;
a hole configured to receive a fitting coupled to a cold plate;
a drain configured to guide a fluid leak from the fitting toward a leak sensor board disposed between the cold plate and the drip tray; and
a lateral wall configured to guide air flow from a fan into a dual in-line memory module (DIMM) area of an Information Handling System (IHS).

### Claim 4 (depends on 3)

The drip tray of claim 3, wherein the leak sensor board comprises a microstrip differential trace moisture sensor.

### Claim 5 (depends on 4)

The drip tray of claim 4, wherein the drain is configured to guide the fluid leak to the microstrip differential trace moisture sensor.

### Claim 6 (depends on 5)

The drip tray of claim 5, further comprising another drain configured to guide another fluid leak from another fitting toward another microstrip differential trace moisture sensor on the leak sensor board.

### Claim 7

In an Information Handling System (IHS), a method comprising:
positioning a drip tray over a leak sensor board disposed atop a cold plate configured to cool a component of the IHS, wherein the drip tray has a concave shape, and wherein the leak sensor board comprises a microstrip differential trace moisture sensor;
fastening the drip tray to the IHS; and
coupling a fitting to the cold plate through a hole in the drip tray, wherein the drip tray is configured to capture a fluid leak from the fitting, and wherein the drip tray comprises:
at least one drain configured to guide the fluid leak toward the microstrip differential trace moisture sensor; and
at least another drain configured to guide another fluid leak from another fitting toward another microstrip differential trace moisture sensor.

### Claim 8 (depends on 7)

The method of claim 7, wherein the drip tray further comprises a lateral wall configured to guide air flow from a fan into a dual in-line memory module (DIMM) area.
