Thermopile vs peltier
WebbI am a professional designer and user of TEC/Peltier modules This instructable, whilst very enthusiastic, and very nicely illustrated won't work as advertised. Moving HEAT is not the same as creating a temperature difference. A Peltier cell will only create a maximum delta T of about 50 C, and pump NO heat, or it will pump its "rated power" at ZERO delta T. http://www.columbia.edu/itc/chemistry/ARCHIVE/chem-c1500TL/experiments/session3/thermocouple/thermocouple.html

Webb10 aug. 2008 · Re: Which thermopile (TEC) is better for power met Hmm, I'll have to check that out. Actually, since this is mostly for experimentation, and I'm receiving three of the same peltier type, I can try out the various paints, etc. to see how they perform. This paint has a high emissivity at around 0.97 though it was measured in the infrared region. WebbPeltier (thermoelectric) cooler performance is a function of ambient temperature, hot and cold side heat exchanger (heat sink) performance, thermal load, Peltier module (thermopile) geometry, and Peltier electrical parameters.
