Thermoelectric cooler/module Answered

I'm working on a project with peltier coolers. I want to get it as cold as I can. What would be my optimum power source? Amps over volts? If it helps I am planning to hardwire the device. and I'll have plenty of room for mounting fans on the hot sides heatsink Here are the specs 50mm x 50mm x 3.64mm 245 - 320 Watts of cooling power Operates from 0-15 volts DC and 0-26 amps Operates from -60 deg C to +180 deg C Thanks

Hi I think using water coolers and a small radiator with a fan will be a good idea but I'd suggest you mention the number of peltiers you are using. of course you are aware that these peltiers are not that efficient but scince you are using them I suggest you ask for detailes from sb who had actually worked with them. I made a project with them and it led to pure failiure I hope you won't end like that.

Thank you, but I've already been there. These coolers are new to me and I'm trying to learn about them. Unfortunaltely that site and the others I've been to don't seem to put the information I need in a language I understand. I guess I need an idiots guide and I'm not ashamed to admit it.

. Since you just want to move as much heat as possible and aren't worried about regulating the temp, I'd just hook up a variable supply w/ammeter. Run the voltage up until you hit 15V or 26A. You'll want to do this with the max delta T you plan to run into.
