A rack mount assembly measurement tool, for determining physical values including air flow and heat loads, includes a front assembly and a rear duct assembly that are non-intrusively and releasably mounted on the front and rear of such rack mount enclosure. Physical values are sensed at multiple vertical locations to enable a determination of overall and localized heat loads within the enclosure. Front sensor values are collected and wirelessly transmitted from the front assembly to a receiver/processor supported on the rear duct, which generates computed values that are displayed in addition to the sensed values.

Heat flow measurement tool for a rack mounted assembly of electronic equipment

A tool is disclosed, for measuring the important thermal characteristics of a unit of electronic equipment, which obtains air flow and temperature readings at both air inlet and air outlet openings of the unit without disturbing cable or wiring connections or otherwise interrupting device operation. The tool pressure sensing element is rotatable between detented positions to permit the tool to be used at both air inlet and air outlet openings. The tool air duct portion may be formed of separate duct portions to enable a single duct portion including the sensing instrumentation to be used with multiple duct portions that conform to electronic device air inlet and outlet openings to impart added flexibility to the tool.

Bidirectional and expandable heat flow measurement tool for units of air cooled electrical equipment

Rack assemblies and methods for cooling one or more rack-based computer systems, as well as data center configurations that utilize the rack assembly. The rack assembly comprises a rack providing support for multiple columns of heat-generating electronic devices and device fans for moving air from an air inlet side of the rack through the devices and through an air outlet side of the rack. The rack assembly also comprises a unitary door having a support frame spanning the air outlet side of the rack and hingedly coupling the door to a rear vertical edge of the rack. The door includes an air-to-liquid heat exchanger panel spanning an air outlet passage inside the support frame so that substantially all of the air passing through the air outlet must pass through the heat exchanger panel. The air outlet passage has a cross-sectional area that is substantially equal to or greater than the cross-sectional area of the multiple columns of heat-generating devices.
