The fundamental problem with these coolers is that they don't actually
provide much cooling. Air conditioners used to be rated in "tons", which
meant the number of tons of ice it would take to provide the same
cooling. A 12,000 BTU air conditioner running for one day (24 hours)
provides about the same amount of cooling as 1 ton of ice.
Weight is very important in an airplane. It would be impractical to
carry enough ice to provide cooling for the length of a typical
several-hour flight.
Race car drivers use "cold suits" to keep cool without the need for air
conditioners, which would add weight and decrease performance.
Basically, they only cool the driver; nothing else! The suits have
little plastic tubes laced through them. An ice chest has 5 lbs or so of
ice, and a pump circulates the cold water through the suit. This is
"good enough" for the short duration of a race. Maybe it would be good
enough for pilots as well?
