Abstract
Embodiments of the present invention include a cooling system and method for cooling a computer rack by circulating liquid coolant through different sections of a rack heat exchanger under separately controlled flow and temperature conditions. In a method according to one embodiment, a first liquid coolant is supplied to a first section of an air-to-liquid heat exchanger. A second liquid coolant is supplied to a second section of the air-to-liquid heat exchanger at a different temperature than the first liquid coolant. Airflow is generated through rack-mounted computer components to the first and second sections of the air-to-liquid heat exchanger. The flow rates of the first and second liquid coolants are independently controlled to enforce a target cooling parameter. The independent operation of the first and second fin tube sections allows for the increased use of un-chilled water without sacrificing heat removal objectives.
