PELTIER COOLER MODULE TECI-12704

Description

The TECI-12704 (TEC1-12704) Peltier Cooler Module is a thermoelectric cooling device that works using the Peltier effect, where one side becomes cold while the other side becomes hot when DC power is applied. It is commonly used in mini refrigerators, CPU cooling experiments, portable coolers, and electronic temperature control systems.

Key Features

• Solid-state cooling with no moving parts
• One side produces cooling, other side produces heat
• Compact 40×40 mm design for small cooling systems
• High reliability with silent operation (no vibration/no noise)
• Fast temperature response when powered correctly
• Reversible function (swap polarity for heating/cooling side change)
• Suitable for DIY cooling projects and electronic enclosures
• Works with heatsink + fan for effective performance
• Long service life under proper thermal management
• Environment-friendly semiconductor cooling technology
