I swear...I didn't do it!!! Not my design...Honest!
Okay, weak attempt at humor.
I'm with Jonnie on this one, looks like some, "make shift", ambient
cooled, evaporator set up. The timer and temperature cut out, is
a dead give away. I think someone had too much time on their hands
and came up with this idea, maybe for a "gutted" box, turned into
some kind of "refrigerator" or...something. Just a thought.
