No Maintenance Filtration/Cooling System for Optical Libraries

      This article describes an close-loop cooling system which has
coarse and fine particle filters to remove the contaminant.

The preferred embodiment of this invention, as illustrated in Figure,
comprises:
  o  An unfiltered cooling path 1 which air flow is provided by a fan
      2, all components 3 to be cooled with unfiltered air are
exposed
      in this path.
  o  A close loop flow path 4 which is contained within the enclosure
      8 of the machine.  The fan 5 provides the air flow for this
      cooling path wherein the components 6 which require clean
cooling
      air are mounted.  The heat is dissipated to the ambient through
      the heat exchanger 7 and the enclosure 8.  A coarse filter 9 is
      installed in this path to remove some contaminant in inside the
      box, the density of said coarse filter 9 is selected so that
      clogging never takes place.  To further remove the the
      contaminant, an air deflector 10 made out of higher density
      filter material is installed to direct some of the air flow to
      the components 6, the rest of the flow goes through the filter
      for the filtration.  If the filter 10 get clogged, the air flow
      to the components 6 won't be reduced.
  o  A replacing air inlet 11 which replaces the air loss 12 through
      the enclosure cracks 13 with a small...
