Induction furnace cooling question!
I'm building an induction furnace for a project and I'm just hoping someone can help with the pros and cons of water cooling types.
My immediate intuition was to use water pumped through the interior of a copper pipe being used, but last night I was thinking it might be more effective to make a sleeve that fits over both sides of the entire coil, placing it in a high flow water jacket.
It would be more complicated, but would also allow just hooking up like sump pump level of flow. It would also have to be magnetically transparent, and set up with standoffs from the coil.
I'll be melting several ounces of brass alloys to pour test coupons
If anyone has experience designing these systems I'd love some feedback.
In case I'm not being clear enough, imagine a coil with a cylinder on the id and od, with an annular cap on both ends, so it's encased in a big tall donut. Then in the top add a few angled intake ports, which feed back to a water pump (exit ports below as well). This would allow high flow water to constantly cool the entire structure, hopefully preventing the coil from annealing during use, and increasing its duty cycle. It would also have the benefit of preventing shorts via contact between the coil and crucible
