Abstract

To meet the cooling requirements of visual display monitors it is usual to provide a large open area in the top of the monitor enclosure. Unfortunately this requirement conflicts with both industrial design and safety needs leading to compromise. It is particularly difficult to provide ventilation at the highest point of the enclosure, at the top front over the CRT, where hot air collects, without impact on the design of the enclosure. This area becomes even more critical when the monitor is tipped back on a tilt table.

Additional Ventilation Slots in a Monitor Enclosure

       To meet the cooling requirements of visual display
monitors it is usual to provide a large open area in the top of the
monitor enclosure.  Unfortunately this requirement conflicts with
both industrial design and safety needs leading to compromise.  It is
particularly difficult to provide ventilation at the highest point of
the enclosure, at the top front over the CRT, where hot air collects,
without impact on the design of the enclosure.  This area becomes
even more critical when the monitor is tipped back on a tilt table.

      This article discloses a method of providing cooling slots in
the front of the bezel, which encloses this critical area.  The
resulting additional ventilation will improve the reliability and
life of the monitor without impact on unit cost.

      Viewed from the front in Fig. 1, the bezel design is such that
there is an outer rim 1 divided from the 'mask'-portion of the bezel
by a relatively deep narrow recess 3.  The mask 2 is either molded as
part of the bezel or as a separately fitted insert.  The method is
applicable to both of these designs.  Cooling slots 4 are positioned
at the bottom of recess 3, where the mask 2 joins to the bezel 1.
Between each slot 4 is a bezel support rib 5.  As can be seen from
Fig. 1 there is very little or no visual impact due to the cooling
slots 4, particularly as the recess is narrow and the mask is as dark
in color.
