[Elecraft] Cooling on a KX2

[Mike Morrell]

Gents: 

 

Please excuse my ignorance here but being a retired professional  engineer
and owning the complete KX? Series,  it seems to me why rely upon natural
convection alone?  If you have the means (indoors) why not provide yourself
a simple DC fan blowing over the heat sink and move the convection component
to forced convection? Forced convection has significant higher heat transfer
than  the conduction/natural convection model that the Elecraft KX? Series
uses.  While going to extended surface area that the Pro Audio fins gives,
nothing beats a blast of cooling air over these fins to move the heat
transfer to a much higher value than natural convection alone.  Another way
of saying this is why does a car draw air over the radiator ( extended
surface) ?
