The TEC1-12715 Thermoelectric Peltier Cooler Module is a high-power solid-state cooling plate that works on the Peltier effect, creating a temperature difference when DC power is applied. One side becomes cold while the other side becomes hot, making it suitable for DIY cooling projects, mini refrigerators, laser cooling, CPU cooling experiments, and portable thermoelectric systems. With a 12V 15A rating, it delivers strong cooling performance when used with a proper heatsink and fan.
Core Module Specifications
• Module Type: Thermoelectric Peltier cooler plate
• Model: TEC1-12715
• Working Principle: Peltier effect (heating + cooling)
• Heat Transfer Mode: One side cold / one side hot
Electrical & Interface
• Operating Voltage: 12 V DC (typical)
• Rated Current: 15 A (maximum)
• Power Consumption: Up to 180 W (approx.)
• Polarity Reversible: Yes (swap +/– to reverse hot/cold side)
• Wire Type: Red (+) and Black (–) leads
Cooling Performance
• High cooling capacity for compact setups
• Requires strong heat dissipation on hot side
• Performance depends on heatsink, airflow, and insulation
• Best results with thermal paste on both sides
Physical Characteristics
• Module Type: Ceramic thermoelectric plate
• Form Factor: Flat square module
• Build: Ceramic plates with internal thermoelectric elements
• Lightweight and easy to mount between plates/heatsinks
Compatibility
• Works with DC power supplies and battery setups
• Suitable for PWM control using MOSFET drivers
• Compatible with Arduino/ESP control (via external driver)
• Can be used with temperature controller modules
Key Advantages
• No moving parts (silent solid-state cooling)
• Compact and easy integration
• Hot/cold direction reversible
• Useful for portable cooling and thermal experiments
Technical Insights
• Always use heatsink + fan on the hot side
• Without cooling, module can overheat and fail quickly
• Use thermal paste for better heat transfer
• Condensation may form on cold side, use insulation if needed
Applications
• Mini fridge and portable coolers
• CPU / electronics cooling experiments
• Laser diode cooling
• Temperature stabilization projects
• DIY thermoelectric research and demos
Pro Tip
• Use a 12V 20A power supply for stable operation
• Add temperature sensor + controller for safety
• Keep module flat and apply even pressure while mounting
• Avoid direct contact with water to protect ceramic plates
Package Includes
• 1 × TEC1-12715 Thermoelectric Peltier Cooler Module
