Modular liquid cooling architecture for liquid cooling

A liquid cooling system for a computer hardware arrangement, the system comprising:

• a first manifold having an inlet opening;
• a second manifold having an outlet opening;
• a group of cold plates extending between the first and second manifolds, each of the cold plates within the group of cold plates having a conduit extending therethrough and fluidly connecting the first manifold to the second manifold to define a first portion of a flow path between the inlet and outlet openings, and the system being convertible between a first state wherein the conduits in the cold plates are fluidly connected in parallel and a second state wherein the conduits in the cold plates are fluidly connected in series, wherein each of the cold plates within the group of cold plates is fluidly connected in series with an adjacent one of the group of cold plates;
• and
• a plurality of valves in the first manifold and the second manifold, wherein the plurality of valves is operable to change the first portion of the flow path between the first state and the second state.
