A thermoelectric cooling (TEC) module is a semiconductor-based electronic component that functions as a small heat pump. By applying a dc power source to a tec, heat will be transferred from one side of the module to the other. It creates a cold and hot side. Using this TEC TEC1-12706 Thermoelectric cooler or thermoelectric Peltier get ice cold in minutes or heat to boiling by simply reversing the polarity.TEC12706 12706 Cooling refrigeration Plate used for numerous applications from CPU coolers to alternate power sources, or even for your own custom car drink warmer/cooler. Since they consist primarily of semiconductor material sandwiched between ceramic plates and have no moving parts. These devices must be used in conjunction with a heat sink water block to avoid burned one side is cooling (Printed model number)and another side is heating (Printed no word) when working. Please radiating the heating side
