SUMMARY

The discussion centers on the Peltier cooling effect, which involves the transfer of heat between two different metals when an electric current is applied. This phenomenon is explained by the thermoelectric effect, where electrons move from one material to another, causing one side to absorb heat and the other to dissipate it. The key takeaway is that the temperature difference arises due to the varying electron mobility and energy levels in the different metals used in the Peltier junction.

PREREQUISITES
  • Understanding of the thermoelectric effect
  • Familiarity with Peltier devices

When the heat gets transferred to one side and the other side gets cold , what causes this cooling effect , why does the heat go from one side to the other on the different metals ,
does this have something to do with the electrons.

I read that before I posted this , what doesn't make sense to me is that why does one get hot and one get cold , why don’t they both get hot , just one hotter than the other.
