Thermoelectric Peltier Refrigeration Cooling System DIY Kit With TEC-12706 Peltier  Semiconductor coolers are a form of solid-state cooling that incorporates both semiconductor technologies and electronic assembly techniques. The thermoelectric Peltier refrigeration cooling system DIY kit is one such example. The DIY kit is a semiconductor cooling kit that uses a TEC1-12706 Thermoelectric Cooler Peltier Module. The kit has 2 heat sinks, the bigger one is for the hotter side and the smaller one is for the cooler side. The bigger the heat sink, the greater dissipation of the heat. The fan, also included in this kit acts as a radiator. This is attached to the bigger heat sink. The TEC1-12706 thermoelectric Peltier module is sandwiched between the two heat sinks. The module will reduce the temperature. Note: This is an unassembled kit.  How To Assemble The Thermoelectric Peltier Refrigeration Cooling System DIY Kit: First, take the large heatsink and the cotton washer (which will hold the Peltier in place), remove the cotton washer’s sticker and place it on top of the large heat sink, making sure to align it. Apply thermal grease or heatsink compound before installing the TEC1-12706 Peltier module (the heatsink compound/thermal grease increases the heat transfer rate). Then, firmly press the TEC1-12706 Peltier module against the heatsink (Remember the cold side of the Peltier module is always the surface with letterings) Apply the heatsink compound/thermal grease above the TEC1-12706 Peltier module and place the small heatsink on top of it and attach the screws Place the brushless dc fan on top of the large heat sink, align it properly, and screw it in place. Next, attach the safety grill to the brushless dc fan and then screw it in place. Read our blog Peltier module working principle where we explained what is a Peltier Cooler, how it works, things to keep in mind while using a Peltier, and applications of Peltier.
