Peltier module

Peltier effect is a converse of seebeck effect.

 

 An effect where by heat is given out or absorbed 

when an electric current passes across a junction between two materials

 

How do Thermoelectric cooler work?

According to peltier effect thermoelectric coolers are operated. The effect creates a temperature difference by transferring heat between two electrical junction. A voltage is applied across joint conductors to create an electric current.

When the current flows through the junction of two conductors, heat is removed at one junction and cooling occurs . Heat is deposited at the other junction.

The main application of peltier effect is cooling. However the peltier effect can also be used for heating or control of temperature.

its my personal experience that if you wanna try any experiment through peltier module just don't buy it online if that offer doesn't have any return policies.
