Peltierelemendi

Peltier element, also known as a thermoelectric cooler or Peltier device, is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy. It can be used either for heating or for cooling, although in practice the main application is cooling. The Peltier effect is the basis for the operation of the device. It was discovered by French physicist Jean Charles Athanase Peltier in 1834. The Peltier effect describes the phenomenon where heat is absorbed or released at the junction of two different types of materials when an electric current is passed through the junction. In a Peltier element, one side of the device becomes hot while the other side becomes cold, creating a temperature difference. The efficiency of a Peltier element is typically low, with only about 5% of the electrical energy being converted into heat. However, Peltier elements are compact, reliable, and can be used in a wide range of applications, including refrigeration, temperature control, and power generation. They are commonly used in portable coolers, small refrigerators, and in scientific and industrial applications where precise temperature control is required.
