Yes, Peltier – ThermoElectric Cooler (TEC).
2x TEC1-12706 in parallel at 12v will draw about 108W.
With very good water cooling or heatpipe of surface area covering both plates fully (=>40x80mm).
It is possible to maintain 25Ltr at 25C in 27C ambient environment.
I have archived better results with improved design, but just to keep folks realistic. After 30C you’re pushing more hot air around the res then removing it.
Fans on Aluminium Heat Sinks are not really going to cut it, the single devices on Heatpipe are very inefficient and generate a lot more heat, pumping this heat into confined environment could make it worse.
Again, everyone is going to have different variables.
Using air extraction, “pipes with radiator” or “separating the hot and cold side of Peltier with in wall design”.
I mention this for the people, who like experimenting.
Readers: If any of this is new, I would not suggest you Google and buy any pre-built device.
Sometimes it’s just about the challenge.
