Thermoelectric separation copper substrate materials generally contain no chemical elements. Thermoelectric separation copper substrate is a special thermoelectric material that uses the thermoelectric effect for energy conversion and separation. It is mainly made of copper and thermoelectric materials. Among them, copper is a metal material with excellent electrical conductivity and is usually used as a conductive part in a circuit; thermoelectric materials are special materials with thermoelectric effects that can generate electrical energy under the action of temperature gradients.
