Now, learning how to TIG weld aluminum without LEAKS !!!
Cool idea and design.
I don't know if you've thought of this or not so I'll just put it out there. I assume you are going to fill the freeze tanks full of water and then put them in a freezer to freeze them. Don't forget the ice is going to expand the freeze tanks, possibly splitting the tanks or at least making them swell, so you might need a little bit of extra clearance in the coolant tank where the freeze tanks slid in.
Also a suggestion for when you weld up the tanks. After the tanks have cooled pour Denatured alchohol in the tanks and tip the tanks to let the alchohol cover the weld seams if there is a leak Denatured alchohol will find it. Hope these help and good luck.
