Semiconductor materials with high thermal potential can be successfully used to create small thermoelectric coolers. The copper plate and copper wire connect the N-type semiconductor and the P-type semiconductor into a loop. The copper plate and copper wire only serve as a conductor. At this time, one of the contacts becomes hot and the other becomes cold. Material: Aluminum, Plastic If the direction of the current is reversed, the hot and cold parts of the connection are opposite. Weight: 0.5 kg, Manufacturer: CWCQGH
