TEC1-12706 6A Thermoelectric Cooler Peltier Module
Solid-State Cooling Compact No Moving Parts
The TEC1-12706 Thermoelectric Peltier Module is a widely used thermoelectric cooling device that can create a temperature difference when powered with DC electricity. It works using the Peltier Effect, where heat is transferred from one side of the module to the other when current flows through it.
One side of the module becomes cold, while the opposite side becomes hot, allowing it to be used for cooling systems, temperature control devices, and DIY refrigeration projects.
