Description

technical field [0001] The invention belongs to the technical field of semiconductor sterilization, and more specifically relates to a method and system for air sterilization and purification of semiconductor thermoelectric sheets. Background technique [0002] The working principle of the semiconductor thermoelectric chip is based on the Peltier effect. When a current flows through a thermocouple pair formed by connecting an N-type semiconductor material and a P-type semiconductor material, heat transfer will occur between the two ends, and the heat will Transfer from one end to the other, creating a temperature difference to form a hot and cold end. The advantages of semiconductor thermoelectric chips are: no need for any refrigerant, continuous work, no vibration and noise during work; very small thermal inertia, fast cooling and heating time; easy to control, through the control of input current, high precision can be achieved temperature control etc. [0003] At prese...
