Peltier modules use the Seebeck effect to create a heat flux between the junctions of two different types of materials. They can be used with both heating and cooling applications, although primarily used in a cooling process. These thermoelectric operate by the Peltier effect and have two sides, one brings heat from one side to the other, ensuring the other side gets cooler. Applications Consumer products (portable coolers, AC units) Scientific devices Military Engineers Features and Benefits No moving parts, so considerably less maintenance Almost perfect temperature control Flexible shape Long lasting
