Abstract

The disclosed embodiments are provide a liquid cooling arrangement and method for a server rack including input and output temperature sensors of the server rack, a liquid cooling subsystem comprising a pump unit to forcibly urge the cooling liquid flow, a liquid distribution circuit fluidly-coupled to the liquid cooling subsystem and the server rack and configured to convey the cooling liquid to/from the server rack, input and output pressure sensors configured to measure the pressure of the cooling liquid flow received, and issued, by the pump unit, and a control unit. The control unit is configured to direct the pump unit to operate at full capacity, quantify pressure differences between the input/output pressure sensor measurements, determine an optimal volume flow rate based on a desired predetermined temperature difference between the input/output temperatures and empirical pump operational characteristics, and adjust the pump unit speed based on the determined optimal flow rate.
