Function: Working principle: When there is a temperature difference between the two ends of the thermoelectric power generation module, the modified module can generate continuous DC electricity, and the greater the temperature difference between the two ends of the module, the greater the direct current generated electricity and the higher the efficiency of thermoelectric conversion. Improve thermal conductivity: During use, paste flexible graphite thermal transfer paper with high temperature resistance and good thermal conductivity at both ends of the module, which can improve the thermal conductivity of the module and improve the performance and durability of the device. Applicable scenes: The thermoelectric generator can be used for power generation, cooling or heating. These modules are specifically manufactured for power generation, but can also be used for cooling or heating applications. Specially designed: The thermoelectric power generator is specially designed for power generation in thermal enterprises. Reliable performance: The Peltier SP1848 27145 TEG modules are much better than standard Peltier modules in power generation applications.
