The system may include a spout connected to a liquid cooling manifold for channeling liquid. The system may also include a collection tray positioned under the spout and configured to contain the liquid from the spout. The system may further include a leak detection rope having a first end coupled to the liquid cooling manifold, a middle portion extending along the spout, and a second end placed inside the collection tray for detection of liquid. ## Claims ### Claim 1 A system for collection, detection and containment of leaked liquid, the system comprising: a spout connected to a liquid cooling manifold for channeling liquid; a collection tray positioned under the spout and configured to contain the liquid from the spout; and a leak detection rope having a first end coupled to the liquid cooling manifold, a middle portion extending along the spout, and a second end placed inside the collection tray for detection of liquid. ### Claim 2 (depends on 1) The system of claim 1, wherein the collection tray has a bottom with a surrounding edge, four side walls extending upward from the surrounding edge of the bottom, and an open top configured to collect the liquid from the spout. ### Claim 3 (depends on 2) The system of claim 2, wherein the collection tray is configured to collect liquid dripped from any components comprising Reservoir Pump Unit (RPU) and Quick Connects positioned above the collection tray. ### Claim 4 (depends on 2) The system of claim 2, wherein at least one of the four side walls is positioned opposite to the liquid cooling manifold, and comprises a sliding door configured to be manually opened and closed by a user. ### Claim 5 (depends on 4) The system of claim 4, wherein the sliding door comprises an optically transparent or semi-transparent material to allow a liquid level in the collection tray to be visually monitored. ### Claim 6 (depends on 2) The system of claim 2, wherein at least one of the four side walls comprises a protruded opening, the protruded opening being able to be fluidly sealed by a cap. ### Claim 7 (depends on 6) The system of claim 6, wherein the cap comprises a transparent or semi-transparent material to allow a liquid level in the collection tray to be visually monitored. ### Claim 8 (depends on 2) The system of claim 2, wherein the bottom of the collection tray comprises a near-rectangular shape. ### Claim 9 (depends on 2) The system of claim 2, further comprising a bracket configured to attach to a rack for servers. ### Claim 10 (depends on 9) The system of claim 9, wherein the collection tray has a front end configured to have a bottom attachment configured to attach to the rack, wherein the collection tray has a back end configured to be supported by the bracket. ### Claim 11 (depends on 10) The system of claim 10, wherein the four side walls comprise a front side wall near the front end of the collection tray, and a back side wall, and two connection side walls connecting to the front side wall and the back side wall, wherein the front side wall has a smaller width and a larger depth than the back side wall near the back end of the collection tray. ### Claim 12 (depends on 11) The system of claim 11, wherein each of the two connection side walls between the front end and the back end comprises at least one section that has the depth continuously increasing. ### Claim 13 (depends on 11) The system of claim 11, wherein each of the two connection side walls between the front end and the back end comprises at least one section that has the width continuously decreasing. ### Claim 14 (depends on 1) The system of claim 1, wherein the spout comprises a first section fluidly coupled to a second section at a first angle. ### Claim 15 (depends on 14) The system of claim 14, wherein the spout further comprises a third section fluidly coupled to the second section of the spout at a second angle. ### Claim 16 (depends on 15) The system of claim 15, wherein the first section is configured to allow the liquid to flow down vertically, wherein the second section and the third section are configured to allow the liquid to flow into the collection tray. ### Claim 17 (depends on 1) The system of claim 1, wherein the leak detection rope is configured to detect liquid. ### Claim 18 A collection tray for collecting liquid, the collection tray comprising: a bottom with a surrounding edge; four side walls extending upward from the surrounding edge of the bottom and surrounding an open top; a front end with a bottom attachment configured to attach to a rack; a back end configured to be supported by a bracket that is attached to the rack; and a leak detection rope having a first end couplable to a liquid cooling manifold, a middle portion arranged for placement along a spout, and a second end arranged inside the collection tray. ### Claim 19 (depends on 18) The collection tray of claim 18, wherein the four side walls comprise a front side wall near the front end of the collection tray, and a back side wall, and two connection side walls connecting to the front side wall and the back side wall, wherein the front side wall has a smaller width and a larger depth than the back side wall near the back end of the collection tray. ### Claim 20 (depends on 19) The collection tray of claim 19, wherein each of the two connection side walls between the front end and the back end comprises at least one section that has the depth continuously increasing and at least one section that has the width continuously decreasing.
