OK, this is ProCooling, so I can nit-pick.
That's the
condensation side
(click the image for a howstuffworks link).
The gas/fluid in a condenser is hot and there's comparatively little fluid movement, so I'd guess these to be inappropriate on at least two counts: restrictive, designed for high coolant-room delta.
[edit] or did you actually mean the evaporation panels from inside a freezer? These aren't designed for fluid flow at all, although they probably aren't much more restrictive than the condenser panel on the back/bottom[/edit]
