Thermo Coolers' Application
The core principle behind thermoelectric generators (TEG) is the Seebeck effect, a physical phenomenon that converts thermal energy directly into electrical energy.
Thanks to their high adaptability and ability to convert energy using temperature differences, 15×15 thermoelectric modules are primarily used in the following applications: Fireplace fans, outdoor grills, fire safety control systems, and control systems, etc.
Semiconductor thermoelectric generator (TEG) is a solid-state power generation device based on the Seebeck effect. It can directly convert temperature differences into direct current electricity, without any moving parts, without noise, and has high reliability.
High-temperature-resistant thermoelectric modules and semiconductor cooling modules are primarily used in fireplace fans.
