Ok, here's what I've got rolling around in my head. A bank of 12v thermoelectric coolers avalable from
All Electronics | Electronic and Electro-Mechanical Parts and Supplies at Discount Prices cooling a heat exchanger (manifold) of sorts. Pull the vented air seat covers input air through this manifold.
Years ago, I built a water cooler for an overclocked PC. With just one TEC chip, I could get frost on the cold block in 20-30 seconds at room temp. The only problem is getting rid of the waste heat from the hot side of these coolers. You would have to vent a heatsink to the outside to pull a sufficient amount of heat to keep these cooling properly...
Here's a link if anyone's interested:
