    Semiconductor electronic refrigeration, also known as thermoelectric refrigeration, or thermoelectric refrigeration, is a refrigeration method using the "Peltier effect", and is known as the world's three major refrigeration along with compression refrigeration and absorption refrigeration.

    The semiconductor refrigerator cooler belongs to electronic physical refrigeration and does not need refrigeration working fluid and mechanical moving parts at all, thus completely solving the application problems that mechanical refrigeration refrigerators such as medium pollution and mechanical vibration cannot solve, and has more significant advantages in small-capacity low-temperature refrigerators. The energy-saving features are of great development and promotion value.

    The effect of semiconductor electronic refrigeration mainly depends on the energy level difference between the two materials in which the charge carrier moves, that is, the thermoelectric potential difference. Pure metal has good electrical and thermal conductivity, but the cooling efficiency is extremely low (less than 1%). Semiconductor materials have extremely high thermoelectric potentials and can be successfully used to make small thermoelectric coolers. Since semiconductor refrigerators are electronic and physical refrigeration, there is no need for refrigeration working fluid and mechanical moving parts, which completely solves the application problems that mechanical refrigeration refrigerators cannot solve, such as medium pollution and mechanical vibration, and has more significant advantages in small-capacity low-temperature refrigerators. The energy-saving features are of great development and promotion value.
