Thermoelectric Peltier Refrigeration Cooling System DIY Kit With TEC-12706
❄️ Thermoelectric Peltier Refrigeration Cooling System DIY Kit (With TEC-12706)
Compact Cooling • STEM Learning • DIY Thermoelectric Refrigerator
The Thermoelectric Peltier Refrigeration Cooling System DIY Kit with TEC‑12706 Thermoelectric Peltier Module is a small thermoelectric cooling system designed for DIY refrigeration, electronics cooling, and educational experiments.
It demonstrates the Peltier Effect, where electrical current passing through a thermoelectric module causes one side to become cold and the other side to become hot.
This kit includes all major parts needed to build a compact cooling unit, making it ideal for STEM education, hobby electronics, and small cooling projects.

⚙️ Working Principle
The cooling system works based on thermoelectric heat transfer.
Step-by-Step Operation
1️⃣ A 12V power supply is applied to the TEC-12706 module.
2️⃣ Electric current flows through the thermoelectric elements.
3️⃣ One side of the module becomes cold while the other becomes hot.
4️⃣ The cold heat sink absorbs heat from the object being cooled.
5️⃣ The fan and hot heat sink remove heat from the system.
This creates a continuous cooling cycle.
