THERMOELECTRIC COUPLE Meaning and
Definition
-
A thermoelectric couple refers to a device consisting of two dissimilar conductors which are joined at both ends. It operates based on the principle of the thermoelectric effect, which describes the conversion of thermal energy into electrical energy. This phenomenon occurs when there is a temperature difference across the junction of the conductors.
The thermoelectric couple consists of a hot junction and a cold junction. The hot junction is exposed to a heat source, while the cold junction is exposed to a lower temperature or a heat sink. The temperature difference established between the two junctions creates an electric potential known as a thermoelectric voltage. This voltage indicates the temperature difference and generates an electrical current when a load is connected to the couple.
The functioning of a thermoelectric couple heavily relies on the Seebeck effect, which is the production of an electric current when there is a temperature gradient across a conductor. The strength of the electric current generated by the couple is determined by the choice of the conductors, as they possess varying thermoelectric coefficients. The thermoelectric efficiency is influenced by factors such as the materials used, temperature difference, and load resistance.
Thermoelectric couples are widely implemented in applications such as power generation, sensors, and cooling systems. They provide a practical and efficient means of converting waste heat into useful electrical energy, making them invaluable in industries such as automobile and aerospace engineering, where energy conservation and sustainability are prioritized.

Etymology of THERMOELECTRIC COUPLE
The word "thermoelectric" comes from the combination of two root words: "thermo" and "electric". "Thermo" is derived from the Greek word "thermos", meaning heat. "Electric" refers to electricity generated or produced by the flow of electrons.
The word "couple" in this context refers to the combination or pairing of two different metals or semiconducting materials to create a thermoelectric effect. Thus, the term "thermoelectric couple" refers to the combination of two metallic or semiconducting materials that generate electricity from temperature differences, based on the thermoelectric effect.
