If the current direction is reversed, the cold and heat at the junction is reciprocal. Semiconductor materials with high thermal potential can be successfully used to make small thermoelectric coolers. Material: aluminum, plastic The copper plate and the copper wire connect the N-type semiconductor and the P-type semiconductor into a loop, and the copper plate and the copper wire only function as a conductive. At this point, one of the contacts becomes hot and one of the contacts becomes cold. Weight: 0.5 KG
