Patent ID: 7639499

Claim:
A liquid cooling apparatus for an electronics rack comprising at least one electronic subsystem chassis, the liquid cooling apparatus comprising: a rack-level coolant manifold assembly comprising a rack-level inlet manifold and a rack-level outlet manifold, the rack-level coolant manifold assembly being configured to mount to the electronics rack; and at least one moveable chassis-level manifold subassembly configured to couple to the electronics rack adjacent to the at least one electronic subsystem chassis and pass liquid coolant to one or more components of the at least one electronic subsystem chassis for facilitating cooling of the one or more components thereof, wherein the at least one moveable chassis-level manifold subassembly comprises a chassis-level coolant inlet manifold and a chassis-level coolant outlet manifold, the chassis-level coolant inlet manifold being coupled in fluid communication with the rack-level inlet manifold, and the chassis-level coolant outlet manifold being coupled in fluid communication with the rack-level outlet manifold, wherein the at least one moveable chassis-level manifold subassembly, when coupled to the electronics rack, is slideable relative to the electronics rack to facilitate access to a removable component of the at least one electronic subsystem chassis, wherein the at least one electronic subsystem chassis comprises at least one removable component.
