PA cooling

Then there's Tygon tubing woven in-and-out of the fins,
a bucket of water... with ice cubes? ... and an aquarium
pump. (;-))

To be realistic ... a 12V computer fan from Radio Scrap
with four sitck-on felt pads resting on top is really easy and
inexpensive.

Re: PA cooling

I know.....I've been thinking about a water cooling system
for my computer instead of noisy fans.......with a goal of
a silent, or almost silent, PC. Thought this may be
interesting to try with the radio as well.

Re: PA cooling

Cool! If they can overclock a CPU to 5 GHz, perhaps we can coax 200W out of
a KPA100.

A messier but cheaper alternative:

and you can cook your french fries when you're done.

OT - Re: PA cooling

That oil bath is much like the "high" wattage RF Jammers I used to work
on in the Air Force.
http://www.dsd.es.northropgrumman.com/rf/ANALQ155.html

The electronics and backward-wave-oscillators (BWO's) were in a bath of
DC200.
(http://www.clearcoproducts.com/pdf/pure-silicone/np-psf-6.pdf)

When the system came on the DC200 was circulated through much of the
electronics and high end systems, and then out and through a radiator
that supported two jammers. The radiators then had ram air passed
through them to supply cooling.

Incidentally, it was huge amounts of fun to stand on a sheet of ice
(northern tier SAC base) and as half of a two man team, pick up these
275+ lb beasts and load them into the belly of the aircraft, connect up
antennas, and cabling. Often times even with or above our heads (at 6'
tall). Ahhhh the memories.
Great stuff.

Don't get me started about Desert Shield / Storm.......
