This makes sense, to have a heat removal mechanism on the back of the peltier... this brings up a question though - if using a water cooling, or more likely, a fan, on the back of the peltier, would it not be easier to use a fan on the back in the first place... However, upon further reading of the thermal exchanges, it seems that using peltier is still more beneficial, as it puts the cold surface (heat removing) next to the electronics, thus cooling it faster, while the excess heat is building up away from the electronics and needs to be removed from the "displaced" location...

The peltiers that i was looking at are 12VDC units, 40mm x 40mm squares with two leads. and about 2-3mm thick... However, now we are looking at a small computer fan and probably a heatsink to go along with a fan... the adventure becomes a little bulkier than i envisioned but i did find fans with heatsinks that are about 55mm x 55mm... so, the jury is still out on this - the phone is doing fine however the heating and battery life on the freaking thing suck... turns out, that folks that i asked about their battery lives on their "smart" phones are complaining about the same things... seems that the battery technology is seriously behind the rest of the computing technologies...

Also, the issue either with the phone or with the technology in general - a USB charger thing is not keeping up with the power requirements of the phone... A factory supplied wall transformer is rated at 1A, which is only 5W and I was getting a message that the phone is not charging as the power supply can not provide adequate juice... I found a 10W/2A transformer, which seems to be a bit better but still, a fully charged battery is slowly dischargin in the car, while on the charger and the phone is running Waze (thanks to Slick for pointing that app to me!!!), and a TuneIn or Pandora while in Car mode... (I have 110VAC outlets in the car)
I found a step down DC-to-DC 15W/3A 12V to 5V converters that need to be hardwired in the car - I hope that 3A might be sufficient... If the 3 Amps will not be enough, I will need to build a custom step down converter, say, 50W or something like that... however, all that amperage is definetely bound to create some serious heat, assuming that the phone will not go up in the smoke before i have a chance to cool it down!!!

It'd be cool driving around with an AC system dedicated for the phone cooling!!!
