Motorized Impeller Wall Exhaust Fans

DATA CENTER COOLING

HOW DO I MANAGE THE EXCESSIVE HEAT PRODUCED IN A DATA CENTER?

Electrical components in data centers generate a lot of heat, which can reduce the overall efficiency and capacity of servers in a data center. Over time, the excessive heat can also cause electrical components to fail or shutdown. To prevent a breakdown, conditioned air (using electronics cooling fans like the DXP series) should be supplied to the inlet of the servers. Simultaneously, hot air must be removed from the exhaust side. This will allow the servers to operate efficiently and keep electrical components well within their design limits.

THE FAN SOLUTION FOR DATA CENTER COOLING

A custom solution of motorized axial impellers and an in-line fan will yield the best results for data center cooling. Motorized axial impellers are used in the sub-floor to boost and supply conditioned air from the computer room air conditioning (CRAC) unit to the cool aisles of the racks. As the cool air enters the servers, it expels higher temperature air in the hot aisles. An in-line fan is used to return the warm air to the CRAC unit and help prevent it from re-circulating back into the server, which would otherwise reduce the cooling efficiency of the server. The size and type of fans used depend on the application; however, this approach will yield a more efficient data center, promote a longer server life and reduce the operating cost of the CRAC unit.

ELECTRONIC CABINET COOLING

HOW DO I REMOVE EXCESS HEAT GENERATED BY ELECTRONICS WITHIN AN ENCLOSURE OR PANEL?

Electronic components generate a lot of heat. Overheating can cause them to trip out or even fail!

To protect components, especially when they are enclosed in a cabinet or panel, cooling fans should be used to draw ambient air into the enclosure and exhaust the heated air into the environment. This allows the electronics to operate efficiently and keeps them well within their design operating limits.

THE CFM SOLUTION FOR ELECTRONIC CABINET COOLING

For smaller enclosures with higher resistances to airflow, Continetal Fan series XR and CMI motorized impellers provide the best solution for electronic cabinet cooling. The backward curved blade design of these centrifugal fans is capable of developing higher pressures to overcome system resistance.

For enclosures with low resistance to airflow, Continental Fan series DXG and DXP AC motorized axial fans provide an effective and economical solution for electronic cabinet cooling. For such applications, these axial fans are ideal for generating high airflow at low static pressure.

For large enclosure sizes and high heat loads, higher capacity fans are required to ventilate the cabinets and cool the electronics inside. Excellent choices for these applications include TMK, TNC, and MNC cabinet cooling fans. These are available with customized mounts to fit any enclosure design.
