TEC1-01703 2V 3.9W 15x15mm Peltier
TEC1-01703 is a 15x15mm Thermoelectric Cooler 3.3A Peltier Module.
Thermoelectric coolers also known as TEC or Peltier Module create 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.
Thermoelectric cooling (TEC) module is a small It is a semiconductor-based electronic component that functions as a heat pump. By applying DC power supply to a TEC, heat is transferred from one side of the module to the other. It creates a cold and a hot side. They are widely used in industrial fields, for example, computer CPU, CCDs, portable refrigerators, medical instruments, etc.
