A subrack assembly can be configured for use with a subrack that includes an installation space for electronic circuit boards, an air distribution duct, an air collecting duct, and a slot. A fan tray can be configured to be slidably and removably received in the slot and can include panel and support one or more electric fans. The panel of the fan tray can at least partly define a first air chamber within the fan tray, and, in cooperation with the subrack, can define a second air chamber within the subrack, with the panel separating the second air chamber from the first air chamber. The one or more electric fans can be configured to drive an air flow through the first and second air chambers, the air collecting duct, and the air distribution duct, to cool the electronic circuit boards within the installation space.

Subrack assembly for electronic equipment

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.
