Yours appears to be a chinese unit like mine, but mounted in a box. Same pcb and likely a very similar power supply.
The welding leads from the induction board to the coil, do get hot, but not enough to require active cooling. The coil is called a tank circuit, essentially a very high current bouncing back and forth is what does the heating.
I used 6 or 8mm plumbing pipe for the coils and fibreglass insulation of ebay/amazon, which is relatively cheap.
Used chinese rectus21 fittings off amazon, for water to the coils. Turned copper 10mm plug and sockets for the electrical connection but dinse may have been more sensible - zoro sells them cheap enough.
