Patent number: 8789384Abstract: 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.Type: GrantFiled: March 23, 2010Date of Patent: July 29, 2014Assignee: International Business Machines CorporationInventors: Eric A. Eckberg, Vinod Kamath, Howard V. Mahaney, Jr., William M. Megarity, Mark E. Steinke

Patent number: 8687364Abstract: A cooling apparatus for an electronics rack is provided which includes an air-to-liquid heat exchanger, one or more coolant-cooled structures and a tube. The heat exchanger, which is associated with the electronics rack and disposed to cool air passing through the rack, includes a plurality of distinct, coolant-carrying tube sections, each tube section having a coolant inlet and a coolant outlet, one of which is coupled in fluid communication with a coolant loop to facilitate flow of coolant through the tube section. The coolant-cooled structure(s) is in thermal contact with an electronic component(s) of the rack, and facilitates transfer of heat from the component(s) to the coolant. The tube connects in fluid communication one coolant-cooled structure and the other of the coolant inlet or outlet of the one tube section, and facilitates flow of coolant directly between that coolant-carrying tube section of the heat exchanger and the coolant-cooled structure.Type: GrantFiled: October 28, 2011Date of Patent: April 1, 2014Assignee: International Business Machines CorporationInventors: Timothy J.

Patent number: 8493221Abstract: One embodiment involves detecting the fouling of an air filter used to filter airflow entering a computer system. An expected airflow rate is obtained from a current fan speed. An expected temperature rise between two positions is computed as a function of the expected airflow rate and the power consumption of heat-generating components, such as servers. An actual temperature rise is obtained from temperature sensors. An electronic alert is automatically generated in response to the actual temperature rise exceeding the expected temperature rise by a setpoint. Different setpoints may be used to trigger distinct electronic alerts.Type: GrantFiled: June 24, 2010Date of Patent: July 23, 2013Assignee: International Business Machines CorporationInventors: Kevin M.
