Description
The 12V 40×40mm TEC Semiconductor Thermoelectric Cooler (Peltier Module) is a solid-state cooling device designed for efficient heat transfer without moving parts. It works by creating a temperature difference between its two sides when powered, allowing one side to cool while the other side heats up. This Peltier module is commonly used in DIY cooling projects, electronic cooling systems, mini refrigerators, temperature control applications, laboratory equipment, and research prototypes. It is compact, reliable, and maintenance-free, making it ideal for both hobbyist and professional use. Available in TEC1-12704, TEC1-12706, and TEC1-12708 variants to suit different cooling power and current requirements.
