Abstract (en)
[origin: EP0369456A2] Air outlet with vortex flow for computer double bottoms The air outlet with vortex flow for computer double bottoms is formed from a swirl disc (1) of plastic having a plurality of radial air guide slits (2/3), these air guide slits (2/3) extending, in the airstream direction (A), at an angle through the disc thickness. A crosspiece (4), which lies at a shorter distance from the outer edge (1a) of the swirl disc (1) than from the disc centre (1b) and occupies the entire slit height, is formed at least in individual air guide slits (2). <IMAGE>
