I'm in the planning stages of a solid state amp. I am considering water cooling... looking for pointers on design ideas, parts suggestions, etc. 73, John NI0K Roger (K8RI) <mailto:k8ri@rogerhalstead.
has anyone ever thought of just immersing the whole amp in mineral or transformer oil? Joe WB9SBD Sig The Original Rolling Ball Clock Idle Tyme Idle-Tyme.com http://www.idle-tyme.com On 2/14/2017 7:0
-- ORIGINAL MESSAGE --(may be snipped) REPLY: it could be done but you still have to get rid of the heat. Keep in mind that so-called "water cooled" amps are really cooled by air. The water is just a
Or you refrigerate the water, but in that case the heat from compression is air cooled. There's a good chance submersing in oil would change the values of some components. 200 fluid of a very low vis
I was even thinking of one of these crazy yet cheap server power supplies. I got one here that can make 13.2 volts at 140 amps! Yeah. wow, BUT the thing is small with two tiny screaming muffin fans,

To make the story short; my goal was dead silent watercooling. I was in the basement and decided to remote an in-line pump and lay the tygon tubing to-from it on the ground as a long heat sink. I hea
OK, I'm going to try again: Water cooling is a mature technology and even with a busted hose, distilled water spraying around in there can be messy, but it's unlikely to be dangerous. Water cooling a

How about instead of "Water" use Mineral or transformer oil? Less chance of contamination... Joe WB9SBD Sig The Original Rolling Ball Clock Idle Tyme Idle-Tyme.com http://www.idle-tyme.com On 2/17/20
water heat capacity is 4.200, mineral or transformer oil are much worse - like 1.650-1850 J/kg/K _______________________________________________ Amps mailing list Amps@contesting.com http://lists.con

cooling works on the premise that the water is brought up to a boil. And thats with normal sea level pressure." Vapor phase cooling doesn't require a completely closed system under pressure. In the
