Peltier Element

A Peltier element, also known as a thermoelectric cooler (TEC), is a solid-state active heat pump that transfers heat from one side of the device to the other when an electric current is passed through it. This process creates a temperature difference, with one side becoming cold and the other hot.

Material:

Peltier elements are constructed from semiconductor materials, typically bismuth telluride (Bi₂Te₃), antimony telluride (Sb₂Te₃), selenium telluride (SeTe), or alloys of these compounds. These materials exhibit the Seebeck effect and Peltier effect. They are arranged in a matrix of p-type and n-type semiconductor pellets, electrically connected in series and thermally connected in parallel. The pellets are sandwiched between ceramic plates, providing electrical insulation and mechanical support.

Purpose:

The primary purpose of a Peltier element is to create a temperature difference. This makes them suitable for applications requiring precise temperature control, cooling, or heating in a compact form factor.

Function:

The Peltier effect is the core principle of operation. When a DC current flows through the element, electrons move from the hot side to the cold side, absorbing heat in the process. This heat absorption creates a cooling effect on the cold side. Simultaneously, heat is released on the hot side as electrons recombine. The magnitude of the temperature difference is proportional to the current and the number of Peltier pairs within the element. Reversing the current direction reverses the hot and cold sides.
