3.3.1 Cooling and Airflow

Cooling
MADE IN DENMARK
Cooling can be obtained in different ways, by using the
cooling ducts in the bottom and the top of the unit, by
taking air in and out the back of the unit or by combining
the cooling possibilities.
Back cooling
The backchannel air can also be ventilated in and out the
back of a Rittal TS8 enclosure for frame size F18 LHD. This
offers a solution where the backchannel could take air
from outside the facility and return the heat losses outside
the facility thus reducing air-conditioning requirements.
NOTICE!
A door fan is required on the enclosure to remove the
heat losses not contained in the backchannel of the
drive and any additional losses generated from other
components installed inside the enclosure. The total
required air flow must be calculated so that the
appropriate fans can be selected. Some enclosure
manufacturers offer software for performing the
calculations (i.e., Rittal Therm software).
Airflow
The necessary airflow over the heatsink must be ensured.
The flow rate is shown in Table 3.1.
