That oil bath is much like the "high" wattage RF Jammers I used to work 
on in the Air Force.

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.......
