Abstract

The invention provides a solar semiconductor refrigeration and thermoelectric power generation demonstration instrument. The demonstration instrument conducts demonstration of refrigeration and power generation through the Peltier effect and the Seebeck effect of semiconductors, and comprises a solar cell panel, a storage battery, two sets of semiconductor pieces, an LCD crystal displaying screen displaying temperature, a digital pipe displaying voltages, a single chip microcomputer, a control circuit, a DS18B20 type temperature sensor, a diverter switch and a main switch. The demonstration instrument system is driven by direct currents generated by the solar energy, the electric power is stored by the storage battery, energy is saved, the environment is protected, and the demonstration device carries out visual demonstration in cooperation with the solar energy power generation technology and the semiconductor refrigeration technology. The LCD crystal display screen displays change of the temperature of air at the refrigerating side of the semiconductor pieces along with time and the value of currents generated during temperature-difference power generation visually and compactly. The demonstration instrument combines a traditional semiconductor refrigeration demonstration device and a temperature difference power generation demonstration device together, the solar power generation technology is additionally provided for the demonstration device, and the demonstration device has the advantages of saving energy, protecting the environment, and being visual and convenient to use, simple in structure and the like.

Description

technical field [0001] The invention relates to a demonstration instrument for solar semiconductor refrigeration and thermoelectric power generation. Background technique [0002] Due to the massive consumption of natural resources during the development of traditional industries, and the waste of resources, industrial pollution and other problems, the development of new energy and energy conservation and emission reduction has become a new direction for the development of modern industry and high-tech. [0003] Traditional semiconductor refrigeration and temperature difference demonstration instruments cannot demonstrate the Peltier effect and Seebeck effect of semiconductor materials at the same time, and the semiconductor refrigeration demonstration instrument uses direct current to power semiconductor chips, and the battery needs to be constantly charged, which is troublesome. Contents of the invention [0004] The purpose of the present invention is to provide a demon...
