  1. Peltiers generate a heat difference by Dhericean · · Score: 5

    A peltier is the active equivalent of a thermo-couple. This means that there are two terminals and a voltage generates a temperature difference between them. Where as in a thermocouple the temperature difference generates a voltage.

    One terminal is normally in a heat buffer of some kind (ice bath, flowing water, etc.). If the voltage is applied one way then the second terminal will become hotter yes. But if the voltage is reversed then it becomes cooler. This is because the first terminal cannot become hotter as its temperatue is buffered.
