TEC1-12706 6A Thermoelectric Cooler Peltier Module
❄️ 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.

⚙️ Working Principle
The module operates using thermoelectric heat transfer.
Step-by-Step Operation
1️⃣ A DC power supply (usually 12V) is applied to the module.
2️⃣ Current flows through 127 thermoelectric junctions.
3️⃣ Heat is absorbed from one side of the module.
4️⃣ Heat is released on the opposite side.
5️⃣ A heat sink and fan are required to remove heat from the hot side.
