High Availability Central Electronics Complex Cooling

      Disclosed is a means of providing fault tolerant air moving
device cooling capability to a split logic cage for high availability
electronics systems.  A blower, ducting, and flap arrangement is
described which provide continued cooling of multiple logic cages in
the event of blower failure.

      The Figure shows the elements: a split cage (1), housing
a multiplicity of cards or books, a plenum section (2), internal
triangular duct section (3), two blower units (4), flappers (5), and
acoustical foam (6).  The blower unit attaches to the plenum with
screws so that an individual blower unit can be removed without
removing the entire plenum from the system.  The blower unit is
guided in by rails so that the connector on the blower unit will
autodock with the connector inside the plenum.  The plenum has a
gasket which fits against the system bulkhead.  Sealing is
accomplished automatically when the plenum is screwed in.  The mating
of blower units with the ducting by means of a circular foam gasket
which provides a tight air seal and vibration dampener.  The blower
units mount in a direction (Z) that directly compresses the gasket
with no shearing of the gasket.  A series of hinged plastic flaps is
situated along the vertical discharge plane of each blower unit.
These prevent backflow through a failed blower.  Each flap is hinged
in two holes.
