The heat exchanger is a water-cooled door that is mounted on the rear of an IBM
42U 1100 mm Deep Dynamic Rack Type 9363 to cool the air that is heated and
exhausted by devices inside the rack. A supply hose delivers chilled, conditioned
water to the heat exchanger. A return hose delivers warmed water back to the water
pump or chiller. In this document, this is referred to as a secondary cooling loop.
The primary cooling loop supplies the building chilled water to secondary cooling
loops and air conditioning units. The hoses for the secondary cooling loop are not
included with this product. The rack on which you install the heat exchanger can be
on a raised floor or a non-raised floor. Each heat exchanger can remove 100,000
Btu per hour (or approximately 30,000 watts) of heat from your data center.
See "Secondary cooling loop parts and services" on page 10 for information about
hoses, water treatment, and coolant distribution units for supplying conditioned
water.
If you would like to procure IBM installation planning services regarding what is
needed to plan for supplying conditioned water and installing the heat exchanger,
see "Installation and support from IBM Integrated Technology Services" on page 22.
If documentation updates are available, you can download them from the IBM
website. The heat exchanger might have features that are not described in the
documentation that comes with the product, and the documentation might be
updated occasionally to include information about those features, or technical
updates might be available to provide additional information that is not included in
the heat exchanger documentation. To check for updates, go to
