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 f ans.
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.
