- thermoelectric cooling is a way to pump heat from one side of a device to the other by applying voltage between two electrodes connected to a sample of semiconductor material. The temperature differential that appears, which is known as the Peltier Effect, can be used for cooling, heating and precise temperature control for various applications.

How do Thermoelectric Coolers work?
2024-10-30 - Technical Q&A Thermoelectric coolers, also referred to as Peltier Coolers, are solid-state heat pumps that require DC voltage to dissipate heat using the Peltier effect. A Thermoelectric cooler consists of an array of p-and n-type semiconductor materials that are soldered between two ceramic plates. During operation, electric current flows through the module to create heat transfer and a temperature differential across the ceramic plates resulting in one cold and one hot side of the Thermoelectric cooler.
