The Thermoelectric Peltier Refrigeration Cooling System DIY Kit is a compact and efficient cooling solution using Peltier (TEC) technology to create a heat differential. When powered, the TEC1-12706 Peltier module absorbs heat from one side and dissipates it on the other, enabling refrigeration without compressors or refrigerants.

The kit includes a heatsink and high-speed cooling fan to maintain thermal efficiency, along with a thermal pad or thermal paste to ensure proper heat transfer. This system is perfect for DIY mini fridge builds, CPU/GPU cooling, electronic component cooling, and STEM educational projects.

Common use cases:

• Miniature fridge projects

• Raspberry Pi or Arduino thermal cooling

• Battery cooling

• Cold drink storage systems

• Thermal physics demonstrations

How to Use:

Assembly Steps:

1. Apply thermal paste or thermal pad to the cold side of the Peltier module.

2. Mount the cold side to the smaller heatsink or cold plate.

3. Attach the hot side to the large aluminum heatsink with the fan.

4. Secure all parts using screws or thermal adhesive.

5. Connect the fan and Peltier module to a 12V DC power supply (rated for at least 5A).

6. After powering on, the cold side becomes cool, and the hot side becomes warm.

Important Tips:

• Always use the fan when powering the module to prevent overheating.

• Ensure good thermal contact with thermal paste for efficient heat transfer.

• The Peltier draws significant current — use a power supply rated above 5A for full performance.

• Ideal for non-continuous applications unless proper insulation and heat dissipation are managed.

Applications:

• DIY Mini Fridge / Cooler

• CPU or Electronics Cooling

• Thermoelectric Air Conditioners

• Battery Pack Cooling

• Scientific Demonstrations

• Solar-powered Refrigeration
