Turbulator Array for Heat Sink Enhancement

      Disclosed is a method which allows field upgrades of the
cooling capacity of air-cooled heat sinks by increasing the effective
heat transfer coefficient at the fin surface.

      As shown in the Figure, field installable turbulator arrays (1)
are placed between the fins of a common plate-fin heat sink (2).  The
turbulator array consists of wires (3) spaced at regular intervals
along a support structure (4).  The thickness of the support
structure is such that it provides a snug fit between the fins of the
heat sink.  Materials for the support structure can be thermally
conductive (i.e., metals) or insulating (i.e., plastics).  The
turbulators can be either straight (3) to force flow acceleration at
the fin surface or wavy (5) to force the air flow to wash back and
forth through fin channel.
