Fault-Tolerant Cooling of Multiple Parallel Processor Modules

      Disclosed is a method of supplying fault-tolerant forced air
cooling to multiple parallel high-speed processor modules.  A blower
pair, flap valve, and plenum sealing system are arranged to provide
continued cooling in the event of blower failure.

      As shown in the Figure, the main elements of the invention
are: a pair of blower impellers (A), a blower housing (B), metal
slide rails (D), a flapper valve (C), a plenum (F), a gasket (E), and
plenum end caps (G).

      The blower impellers dock into a sheet metal housing (B), which
in turn slides on metal rails (C) to dock into a system frame.  One
impeller inlet (H) faces-up, the other faces-down, so that the scroll
discharges are adjacent and the adjoining duct occupies a compact
common cross sectional flow area.  A V-seal gasket (E) connects the
blower housing (B) to the mating plenum bulkhead and prevents flow
leakage from gaps caused by misalignment tolerances.

      A single vertically-hinged flap (C), situated between the
blowers, functions as an anti-backflow check valve.  Under normal
operation the flap self-aligns with the airflow and permits both
impellers to feed the plenum.  In the event of impeller failure, the
flap swings shut over the failed blower discharge to prevent backflow
through the failed blower.
