OOI, have you ever seen or used a cooler box that works by the
evaporation of water because I haven't? shrug
When I was young and domestic fridges were the exception
rather than the rule, my mum had a butter cooler which worked
on that principle.
It was an unglazed porcelain urn with matching lid which was
half filled with water and a glass container that fitted in
the top to hold the butter.
I'm quite sure that larger versions were made as it was a
simple but effective way of achieving the objective.
Now you mention it it does remind me of that sort of solution. Not
sure I've seen a camping cooler box in that form though. ;-)

Inverted, soaked, unglazed pots for milk bottles to keep them cool for
people who were out when the milkman came used to be commonplace.
