1. A method, said method comprising:flowing a cooling fluid through a flexible tube into each rack container of a plurality of rack containers, each rack container comprising a plurality of rack units via a cooling conduit that encapsulates the flexible tube and is secured at a first port on a top surface of said each rack container,
wherein the rack units of the plurality of rack units are stacked in a first direction that is parallel to a floor,
wherein the cooling conduit comprises a first segment, a second segment, and a third segment,
wherein the first segment is linked to, perpendicular to, and in direct physical contact with, the second segment through a first articulation,
wherein the second segment is linked to, parallel to, and in direct physical contact with, the third segment through a second articulation,
wherein the first and second articulations are configured to rotate horizontally in a plane parallel to the floor to enable the flexible tube to maintain smooth contact with the top surface of said each rack container,
wherein the cooling conduit of said each rack container is located at a front side of said each rack container, and
wherein an exhaust conduit of said each rack container is located at a back side of said each rack container.
