Device that circulates mineral oil and cools it?

Cars and trucks use rubber hoses for cooling water without big issues so long as it is maintained.

plastic reacts chemically with mineral oil and breaks down. there are purpose built rigid tubes such as copper and glass which you cut down to size for this application. I'm not quite sure what it has to do with copper being conductive or glass being too brittle? this is the standard method used for years in the PC industry

look at CPU voltages vs induction heater voltages. you have to be more careful and use higher quality insulators and the failure mode will be worse. It's going to be very high current 170-300VDC @ 1000A in the tank vs like 3-12VDC @ much less A-DC (the processor does not use high voltages). And the PC supply might have a e-fuse or current limit or something. That tank is just going to blow something up immediately if there is a low impedance formed some where.
I think you will want to up the ante compared to cooling a computer unless its a piss weak low voltage heater.
OM222O:
that's true but AFAIK mineral oil is a good insulator so unless there is something extremely wrong with the installation where the tubes are touching the supply, it should be fine? in case you want extra safety, it's super easy to just ground the tubes as well?
james_s:
I was assuming using water, not mineral oil. We've already established that immersion in mineral oil is pointless for this thing. Just pump water through the work coil.
