Here's an idea which follows on the principles you just mentioned. It
requires an old fridge that still works, a couple of small electric
boxer fans, some clothes dryer flexible hose, and some ingenuity.

The first step is to build an air tight enclosure around the back of the
fridge over the evaporator coils. Perhaps just thick plastic film will
work as well as a wooden box. Attach the hoses at opposite ends, say top
and bottom, and direct them to the outdoors some distance apart so the
air can't feed back into them. One hose will be the air intake and the
other the heat exhaust. In line with the intake hose mount a first fan
to push air through.

Second step: the freezer compartment, jam the food channel shut,
disconnect the air circulating fan, rip off the insulation over the
cooling coils to expose them, make a hole either side of the freezer and
jam a hose into each hole so you can redirect the cold air to a
distance, one hose will be the air return, and mount the other fan
inside so it pushes the return air through the cooling coils. I have no
idea how many BTU's might be extracted from the inside air with such a
contraption.
