Arrangement for ventilating electrical and electronic units, has air distributor with protrusion-free surface from which openings and guidance devices extend into air accumulation volume

摘要

The arrangement has an air distributor (11) between a fan unit (7) and the units to be ventilated and with air passage openings and air guidance devices and an air accumulation volume between the fan unit and air distributor. The air distributor has a continuous, essentially plane, protrusion-free surface bounding the air accumulation volume from which the openings and guidance devices extend into a region of the accommodation chamber (5).
