Abstract
A data center cooling system includes a housing to contain electronic racks of IT components operating therein, a coolant distribution unit (CDU) situated within the housing to control a liquid flow of a cooling liquid. One or more liquid cooling devices are disposed on the IT components to receive a first liquid from the CDU, to exchange or extract heat generated from the IT components, to transform the first liquid to a second liquid with a higher temperature, and to transmit the second liquid back to the CDU. The CDU is coupled to a heat transfer system to dissipate the exchanged heat to an external environment. The data center cooling system includes an airflow delivery system to generate a direct or indirect airflow to travel through the servers of the electronic racks to remove heat generated by the servers to the external environment eliminating chiller and IT fans.
