Military HD-347/U Electronic Equipment Air Cooler (Collins Blower 1990-3)
Collins Blower 1990-3, shown in figure 20, is a centrifugal blower capable of delivering 125 cfm of air at a pressure equivalent to 1.83 inches of water. The 1990-3 includes a double-pole, single-throw switch which is actuated by air pressure. The switch contacts are used as interlocks for the primary power to the system. A block diagram of the 1990-3 is shown in figure 21. The unit mounts in a standard 19-inch open-type rack. Cooling air is supplied to the units mounted in the rack through a central air duct, All power and control connections are made through an 8-pin connector located on the top of the 1990-3. Access to components is obtained by removing the front cover and air filter.
