TEC1-12715 Peltier Module
❄️ TEC1-12715 Thermoelectric Peltier Module
High-Power Cooling Device • Solid-State Heat Pump • DIY Refrigeration
The TEC1-12715 Thermoelectric Peltier Module is a thermoelectric cooling device that works based on the Peltier Effect. When electrical current flows through the module, one side becomes cold while the opposite side becomes hot.
Unlike traditional compressors, the Peltier module has no moving parts, making it compact, reliable, and ideal for portable cooling systems, electronic temperature control, and DIY refrigeration projects.

⚙️ Working Principle
The module works using the thermoelectric cooling effect.
Step-by-Step Operation
1️⃣ DC current flows through the module.
2️⃣ Heat energy is transferred between semiconductor junctions.
3️⃣ One surface absorbs heat and becomes cold.
4️⃣ The opposite surface releases heat and becomes hot.
5️⃣ A heat sink and fan are used to dissipate heat from the hot side.
