William Mark Megarity - Raleigh NC, US

Assignee:

International Business Machines Corporation - Research Triangle Park NC

International Classification:

A47B 81/00

US Classification:

3122232

Abstract:

A mount for a bezel/air filter assembly for use in mounting the bezel/air filter assembly directly to the rack or cabinet in which electrical equipment is mounted or contained. The mount is affixed to the rack or cabinet rather than to the electrical equipment mounted or contained in the rack or cabinet, making use of the normally unused frontal area along the rail forming the front of the rack or cabinet, maximizing air flow to the equipment mounted in the rack or contained in the cabinet and allowing greater packaging density. Also, by using the rack or cabinet (rather than the equipment) as a support element, the mount is substantially stronger than if the mount was affixed to the chassis.

International Classification:

F28F 27/00
F28D 15/00

US Classification:

165200, 16510433

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.

International Classification:

F28F 7/00
B23P 19/00

US Classification:

165185, 29428

Abstract:

Dual heat sinks, apparatuses, and methods for installing a dual heat sink for distributing a thermal load are provided. Embodiments include a top base to couple with a first integrated circuit of a first board and to receive a first thermal load from the first integrated circuit; a bottom base to couple with a second integrated circuit of a second board and to receive a second thermal load from the second integrated circuit; and a thermal dissipating structure coupled between the top base and the bottom base, the thermal dissipating structure to receive and distribute the first thermal load and the second thermal load from the top base and the bottom base; wherein a height of the thermal dissipating structure is adjustable so as to change a distance separating the top base and the bottom base.

International Classification:

G05D 23/20

US Classification:

700300

Abstract:

Improving the operating efficiency of a rear door heat exchanger, including: determining, by a ventilation management module, a temperature differential between two temperature sensors in the rear door heat exchanger, the temperature differential indicative of cooling efficiency in the rear door heat exchanger; determining, by the ventilation management module, whether the temperature differential is greater than a predetermined threshold; and responsive to determining that the temperature differential is greater than the predetermined threshold, taking corrective action by the ventilation management module.

International Classification:

B23P 15/26

US Classification:

2989003

Abstract:

An air-cooling method is provided which includes providing a heat exchanger door and a catch bracket. The door is hingedly mounted to the air inlet or outlet side of an electronics rack, and includes: a door frame spanning at least a portion of the air inlet or outlet side of the rack, wherein the frame includes an airflow opening which facilitates airflow through the rack; an air-to-coolant heat exchanger supported by the door frame and disposed so that airflow through the airflow opening passes thereacross; and a door latch mechanism to selectively latch the heat exchanger door to the rack. The catch bracket is attached to the rack and sized to extend from the rack into the heat exchanger door through a catch opening, and the door latch mechanism is configured and mounted within the heat exchanger door to physically engage the catch bracket within the heat exchanger door.

US Classification:

165 111

Abstract:

A heat exchanger core optimization method is provided for a heat exchanger door which resides at an air inlet or outlet side of an electronics rack, and includes an air-to-coolant heat exchanger with a heat exchanger core. The core includes a first coolant channel coupled to a coolant inlet manifold downstream from a second coolant channel, and the first channel has a shorter channel length than the second channel. Further, coolant channels of the core are coupled to provide counter-flow cooling of an airflow passing across the core. The core optimization method determines at least one combination of parameters that optimize for a particular application at least two performance metrics of the heat exchanger. This method includes obtaining performance metrics for boundary condition(s) of possible heat exchanger configurations with different variable parameters to determine a combination of parameters that optimize the performance metrics for the heat exchanger.
