Overview
The TEC1-12706 Thermoelectric Cooler is a semiconductor-based electronic component that functions as a small-scale heat pump. By applying a 12V DC current, the device transfers heat from one side to the other, creating a temperature differential of up to 65°C. With no moving parts, no vibration, and no refrigerant, it is the safest and most compact way to build cooling systems for students, hobbyists, and engineers.
Key Features
Instant Cooling: Reaches sub-zero temperatures on the “cold side” within seconds of being powered.
Solid State Reliability: No moving parts or gases, ensuring a long lifespan and silent operation.
Dual-Purpose: Reverse the polarity of the power supply to switch between cooling and heating modes.
Precise Control: Temperature can be accurately managed by varying the input voltage/current.
Compact Footprint: At only 40mm x 40mm, it fits into tight spaces where traditional compressors cannot.
