Thermo electric pile - is three element generator giving opposed polarity outputs

摘要

Pile is made up three distinct materials bonded together a metallic heat sink or collector forms one layer, a second layer produces a negative potential across the junction, a third layer produces on the other face a positive. Both of these materials can be para or ferro magnetic and will have been subjected to a high magnetic field during manufacture such that temperatures of 600 deg.C can be tolerated.
