I wonder how one of these little $100 fridges would work with their useless
little freezers filled with blocks of aluminum as holding plates so you
could flip them on when you crank the engine (or install a simple relay to
do it automatically). Btu is Btu. It's not rocket science. The more you
open it, the more it draws. The cheap one's R-value could be easily
increased with some sheet styrofoam to pack it in with or glued to its
sides.
I have some big aluminum heat sinks I got from somewhere. I think I'll
play a little with them stuffed into the little freezer and see how that
works as a holding plate....hmmm...(c;
Badly.
You would be much better off filling the freezer with a phase change
fluid that melts/freezes somewhere in the desired temperature range.
Water, for instance...
The exterior of a typical little bar fridge is a heat dissipation
surface, so insulating it from the surroundings would be a bad idea.
