  Semiconductor coolers are thermoelectric coolers, also known as Peltier coolers or thermoelectric modules, which act as a heat pump. These coolers act when a low direct current (DC) voltage is passed through them. The voltage causes the semiconductor cooler to move the heat from one part of the cooler to another part, thus cooling the former area while heating the later area. Semiconductor coolers market  are generally made of alternating n and p type semiconductors, which results in cooling at the junctions of these semiconductors, while heat is being absorbed from the environment. Reversal of polarity of the DC voltage will cause a reversal in the cool and hot areas of the pump, thus allowing for temperature control of the semiconductor module in a precise manner. The same thermodynamic principle is also applied for portable refrigerators and beverage coolers, among others, however on a larger scale. In general, semiconductor coolers are accompanied by a heat sink, absence...
