Abstract

Disclosed is a top cover for a computer frame that enables three requirements to be met in a single structural package: 1) water protection for the circuitry inside the frame, 2) acoustical noise attenuation, and 3) vertical discharge of air from the cooling fans or blowers located inside the frame. Water which might fall on the top surface of the cover, such as from an overhead sprinkler system or other source, is diverted to fall over the side covers. Air is directed out the top through a series of internal baffles which are lined with acoustically absorptive material to provide the noise attenuation.

Water Protective, Acoustically Attenuating Top Cover for Computer Frame

       Disclosed is a top cover for a computer frame that
enables three requirements to be met in a single structural package:
1) water protection for the circuitry inside the frame, 2) acoustical
noise attenuation, and 3) vertical discharge of air from the cooling
fans or blowers located inside the frame.  Water which might fall on
the top surface of the cover, such as from an overhead sprinkler
system or other source, is diverted to fall over the side covers.
Air is directed out the top through a series of internal baffles
which are lined with acoustically absorptive material to provide the
noise attenuation.

      In three possible implementations illustrated in the figures
the top cover 1 is placed over the open top area of the computer
frame 2 so that cooling air discharges along path 3, while water is
diverted along path 4.  In Fig. 1, a "J-trough" 5 allows air to flow
out freely in a vertical direction but prevents water from spilling
into interior 6 of frame.  In Figs. 2 and 3, "deflector plate" 7
diverts water through narrow channel 8 while air takes easier path
through wider channel 9.  Acoustically absorptive foam 10 lines
surfaces not in contact with water and may be applied as in Fig. 3 to
provide greater noise attenuation than in either Fig. 1 or Fig. 2.
