TEC1-12705 12V 49W 40x40mm Peltier

TEC1-12705 40x40mm Thermoelectric Cooler is a 5A Peltier Module. The module contains 127 semiconductor pairs that very effectively cool and heat up to 70°C in a 40mmx40mm area.

Thermoelectric coolers are also known as TEC or Peltier Module each It creates a temperature difference on both sides. One side gets hot, the other side gets cold. Therefore, they can be used to heat something or cool something, depending on the side you use. You can also take advantage of the temperature difference to generate electricity.

This Peltier works very well as long as you remove the heat from the hot side. After turning on the device, the hot side heats up quickly, the cold side cools down quickly. If you don't remove the heat from the hot side (with a heatsink or other device), the Peltier will quickly reach stasis and do nothing. We recommend using an old computer CPU heat sink or other metal block to draw heat from the hot side.
