I was thinking about cutting a couple holes in the lid of a small chest freezer and either putting a keg of glycol in there, or maybe just filling the whole thing with glycol, then running a copper coil or two through the whole thing. Figured a big reservoir like that would provide a ton of cooling, especially if I let it sit overnight.
Would run cooling fluid through the coils? Or even just pump the liquid directly and not even both with the coils at all?
My only worries would be the freezer running too much? (Blow the pump on my $100 used freezer) or hitting a coil or something in the lid?
Any thoughts on the topic? Seems like it’s a good potential combination of cheap & effective.
