Has anyone experimented with peltier devices to make their own chiller? I am thinking of giving it a try. My plan is to use a brand new aluminum transmission oil cooler, this will provide a great dealt of conducting surface for cooling, along with a 12 inch 12v fan for the cooling side, a computer heatsink and fan for the other side and sandwiched in between two 136 watt 12v Peltier devices. I will need a 12v 30 amp power source, a 12 volt temperature controller that triggers two devices one for cooling and one for heating, and finally a couple of 12v 30 amp relays. I believe I can do this for under 150. and get all the parts from ebay. They have a Peltier temperature controller that works with 9amps that would have been nice to use however, my project will use at least 18 amps so I am forced use the relays to reverse the polarity to switch between heating and cooling. I will update this post with the results of this project.
