3.2 Principle of operation of cooling
Air that has been heated by the servers (to 35°C/95°F, e.g.) is fed to a specially designed air/water
heat exchanger using high-performance fans.
There the air is cooled to approx. 20-25°C / 68-77°F, and fed to the front of the server.
The server fans can draw in the air and feed it over internal equipment.
Chilled water is provided by a chiller made available on site.
Below the heat exchanger there is a condensed water tray with a 5/8“ outlet.
When the cooling system fails
, the unit doors have to be opened
to prevent a build up of heat in the cabinet. In this case the heat load is
dissipated into the room where the unit is located.
When the CoolTherm fans fail
, the unit doors are to be opened
to prevent a build up of heat in the housing. In this case the heat is
emitted into the room where the unit is installed as a thermal load.
If the rear door (with fans) is opened, the front door
must be opened.
