A Peltier Module is a semiconductor device that generates temperature differences in response to an electronic current, and vice versa. Most commonly it is used as a cooling device. This module consists of 127 peltier couples mounted between ceramic plates.

Apply current flow in one direction and heat is transferred in a corresponding direction. Reverse the current and the direction of heat transfer reverses. The input current can be pulsed to moderate the degree of temperature transfer. In most cases you will need to provide a heat sink, fan or draft to dissipate the thermal energy.
