Abstract
An air distribution system for electronic components utilizes an air supply unit with a silencer unit. The silencer unit attenuates sound associated with the air unit blowers with inlet and discharge silencers. The blowers have check valves which provide for isolating each blower for continued operation even with one blower. The cooling air is transported to a circuit board module stack from the blowers through ducts and a bank of rod valves. The valves allow maximum air flow to the modules with minimum resistance. The ducts have a flexible portion which have quick disconnects and act to isolate the modules from vibrations and static. The modules utilize channels in an air plate with different sized baffles to provide even distribution of cooling air to the printed circuit boards.
