Hey Trackrat!
Hard to tell from the lame description of the electronic system you link to, but I would have to assume that it's some sort of Peltier device. Here is a link to a Wiki description of the device:
http://en.wikipedia.org/wiki/Thermoelectric_effect
When I worked in the bio-tech instrumentation field as an ME, I designed a machine that used a Peltier cooler. What I found was that I had to provide way more ducting of the hot side than I had anticipated. The process of creating cool meant that you had to dissipate a LOT of heat. I imagine that you'd have to run a duct from the device out to the outside.
Besides, that thing is way too damn expensive!
