Comment High density ( 52 KW per rack ) (Score 2, Interesting) 409
The only effective way to cool 52 KW racks
is with a cooler in front of the rack -
This unit requires a 15 ton capacity coil,
but can be lined up side by side. Each rack stays cool.
Smaller units work the same way -For example- put a 4 ton coil in front of a rack of 40 opterons - cold air in the front regardless of the room temperature. 80 opterons / 8 ton coil The computers provide the fan - no crac unit needed -
Size the cooler for the rack, hook it to the cold water, - repeat as needed.
This adds 8 to 14 inches to rack depth - and has no hot spots.

Bigger computers - bigger coil - one rack at a time I can cool any installation you have !
I am going to roll out the first installation this summer.
From my patent application -
Background of the Invention
[003]Computers are sometimes cooled by cooling the air in the room in which the computers are located. A typical cooling system cools air and moves it through the room with the devices in the room that need to be cooled. When air is used as the cooling medium, variations in airflow occur, particularly when the heat density rises in a region of the equipment room, or when the absolute heat load approaches the maximum load that the air can handle. In an effort to solve resulting problems, systems have been made in which the devices that heat up are placed inside of a closure and the air inside the enclosure is cooled. These systems have been found to be inadequate when the heat density is above about 8 Kw. None of the existing systems are able to effectively operate in an environment in which the heat density is between about 20 to about 40 Kw. Yet, manufacturers are starting to make computer equipment in which that much power exists in the system. Currently, when the heat density is high, the systems are provided with greater floor space and larger air handlers and chillers. This approach has led to the creation of "hot spots" in the equipment. The known systems fail when the power level raises to about 400 watts per square foot, or when the cooling requirements vary substantially in a given space.
[004]When airflow in a single rack approaches about 3,000 cubic feet per minute, and an aisle of about 20 racks approaches 52,000 cubic feet per minute, the conventional systems cannot handle the airflow in a computer room of conventional size. The use of larger rooms is expensive and they are still subject to the airflow problems that are created. These problems include the creation of "hot spots" which are regions in the room that are not sufficiently cooled and in which the devices that generate the heat are adversely affected by the heat. There is a need for a cooling system that avoids the problems of the prior art systems and which eliminates the "hot spots". A principal object of the present invention is to fulfill this need.
ABSTRACT
A device that in use generates heat is positioned within an enclosed space that includes an ambient air inlet, an outlet and an air mover for moving ambient air through the space from the ambient air inlet to the outlet. A cooler comprising coils and passage ways defined by and between the coils to which ambient air moves from the inlet of the cooler to the outlet of the cooler. Position in the cooler with its outlet in register with the ambient air inlet for the enclosed space. Using the cooler to cool the ambient air that is immediately forwardly of the ambient air inlet for the enclosed space. Using an air mover in the enclosed space for moving the cooled ambient air into the ambient air inlet, through the enclosed space, and out from the outlet of the enclosed space.
