Product Description of Thermoelectric Cooler
The thermoelectric generator is assembled using high-strength bismuth-based thermoelectric material, high-thermal-conductivity, high-insulation DBC (directly bonded copper) ceramics, and high-temperature solder, making it suitable for use in environments where the hot side reaches 200°C.
Product Features of Peltier Cooler
High performance: Achieves a power conversion efficiency of 5% even under a 200°C temperature difference.
High reliability: Typical service life exceeds 10 years.
High-temperature resistance: The hot side can operate in environments up to 200°C.
Compliant with RoHS requirements.
Customization services available.

Performance Curves of Peltier Cooling Module
At a hot-end temperature of 130°C, the temperature-versus-output voltage and temperature-versus-output current curves

At a hot-end temperature of 200°C, the temperature-versus-output voltage and temperature-versus-output current curves

1. The horizontal axis of the graph represents the temperature difference—that is, the difference between the temperatures of the hot and cold surfaces. The greater the temperature difference, the higher the output voltage and current;
2. For the definitions of open-circuit voltage and open-circuit current, refer to P1. Both open-circuit voltage and open-circuit current can be measured with a multimeter when there is no load;
3. The left vertical axis represents voltage data, and the right vertical axis represents current data;
The core principle behind thermoelectric generators (TEG) is the Seebeck effect, a physical phenomenon that converts thermal energy directly into electrical energy.
20*20*2.95mm thermoelectric generation: Compact, self-powered via temperature difference, reliable power for low-power devices in harsh environments.
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.
