ABSTRACT:
A ventilator insert for cooling electronic components in cabinets and racks, the insert including a ventilator housing provided with a cover plate and a front plate. A plurality of blowers are held in the cover plate. The blowers are supplied with air by way of different air intake channels whose inputs constitute partial regions of the inlet opening and start at the front plate. Each row of blowers has an associated separate air intake channel. By differently dimensioning the entrance cross sections of the air intake channels, the cooling air discharged by the ventilator insert can be adapted to requirements while ensuring uniform cooling of the components.
