Abstract

A device for ventilating electronic and electrical equipment, subassemblies and components, which are placed in casings, cabinets and subassembly carriers. The device is particularly suitable for slide-in fan modules, which are equipped with axial flow fans and positioned at a relatively small distance from a reception space for the electrical and electronic equipment, etc. to be ventilated. Between the objects to be cooled and the fan unit is provided an air distribution plate, which has punched out air passage openings. In order to achieve a diffuser action and partial direction change of an air volume flow, air deflecting surfaces with a predeterminable inclination and in clearly defined areas are formed by a punching and bending process.
