Device that circulates mineral oil and cools it?

I agree there, mineral oil is a huge pain, I've used it for small HV transformers and it's almost impossible to keep it contained. It wicks up inside wires and leaks out every conceivable place, it makes a sticky mess all over everything, once it's been immersed you pretty much have to just throw it all away if anything fails. I don't see any advantage of using it over forced air in this application.

OM222O:
literally any water cooling loop would work just fine. don't use plastic tubing as it will get brittle and breaks.rigid tubes like copper/glass/etc are better options.

james_s:
Plastic tubing works fine, metal is conductive and glass is brittle, it doesn't seem very practical to be running fragile glass tubes full of water around electronics. Cars and trucks use rubber hoses for cooling water without big issues so long as it is maintained.

If he really wanted to, he could use Galden or other fluorinated heat transfer fluids... nonflammable and less viscous than mineral oil, but costs even more.

Plasmateur:
Hey thanks everyone. It appears forced air is probably going to be the best way to go then. But then I'll probably have to mod the induction heater by switching out the caps.

The heater is here: https://www.amazon.com/Yosoo-Voltage-Induction-Heating-12V-48V/dp/B01C70G7Y8/ref=sr_1_4?keywords=induction+heater&qid=1555120176&s=gateway&sr=8-4

Those caps get super hot, and I don't feel like forced air is going to do the trick since I'm going to have to run this over some length of time.
