What are High Temperature Thermoelectric Coolers (TEC)?
Thermoelectric coolers (TECs) are solid-state devices that transfer heat from one side of the device to the other by using the Peltier effect. When an electric current flows through two different conductors, heat is absorbed on one side and released on the other, creating a cooling effect. High temperature thermoelectric coolers specifically refer to devices capable of operating effectively at elevated temperatures, typically above 200°C, where conventional TECs might struggle to maintain efficient cooling. These coolers are critical in applications requiring high-performance thermal management under challenging conditions.
In contrast to traditional cooling technologies such as compressors or fans, TECs have no moving parts, making them more reliable and long-lasting. Additionally, they offer precise temperature control, making them ideal for sensitive applications where temperature stability is paramount.
