And again, if you are pumping warm water back into the ice chest, let's
just say AT ambient
temperature, the insulation of the chest will do no good.

Good for you, you finally made a statement that is true! *Once* the water
reaches ambient the insulation of the chest is worthless.

What you're failing to grasp is that up until that point the cooler is
focusing the heat gain at the heat exchanger where it is useful, whereas the
cardboard box will allow much more heat to be absorbed from the box itself,
the floor the box is sitting on, and the air around the box.
