Thermoelectric Peltier Refrigeration Cooling System DIY Kit without TEC-12706
Thermoelectric Peltier Refrigeration Cooling System DIY Kit (Without TEC-12706)
DIY Cooling Thermoelectric Technology STEM Learning
The Thermoelectric Peltier Refrigeration Cooling System DIY Kit is a compact thermoelectric cooling assembly designed for building small cooling systems and learning projects. This kit demonstrates the Peltier Effect, where electric current passing through a thermoelectric module creates a temperature difference between two sidesone side becomes cold and the other hot.
This version of the kit does not include the TEC-12706 Peltier module, so the thermoelectric module must be purchased separately.

Working Principle
The system operates based on the Peltier thermoelectric effect.
Step-by-Step Operation
1 Electric current passes through the Peltier module.2 One side of the module becomes cold while the opposite side becomes hot.3 The cold heat sink absorbs heat from the object being cooled.4 The hot heat sink and fan remove heat from the system.5 Continuous cooling is achieved as long as power is supplied.
