Cooling assembly for high power density computer racks

A cooling system, comprising:

• a rack system;
• a plurality of heat exchangers vertically arranged beneath the rack system, wherein a primary heat exchanger of the plurality of heat exchangers is disposed adjacent to a front portion of the rack system, and a secondary heat exchanger of the plurality of heat exchangers is disposed adjacent to a rear portion of the rack system;
• and
• a liquid distribution sub-system, comprising:
• one or more supply pipes disposed between the primary and secondary heat exchangers and configured to deliver a cooling fluid to the plurality of heat exchangers, wherein the cooling fluid is warmed by the plurality of heat exchangers;
• one or more return pipes configured to collect the warmed cooling fluid from the plurality of heat exchangers;
• a manifold coupled to at least one of the one or more supply pipes and the one or more return pipes, wherein the manifold is configured to distribute the cooling fluid throughout the rack system;
• and
• one or more liquid pumps disposed within the rack system, the one or more liquid pumps configured to communicate with the plurality of heat exchangers.
