In the old days and still in many refrigerators, the freezer was actually inside the refrigerator cabinet. It is the coldest place in the fridge where the cooling coils are located, and when cold air leaks out of it, that cold air falls down into the outer cabinet of the refrigerator. Warm air from the
refrigerator portion rises up to the freezer section and gets cooled in turn.This is also why the vegetable "crispers" are located in the bottom of thefridge, I believe--the coldest air from the freezer falls there first, keepingthe fruit and veggies freshest.

Freezers are always on top of a fridge due to the nature of convection. The natural law of convection is that warm air rises while cold air falls, so the freezer at the top provides cold air for the other compartments at the bottom of the freezer.
