半导体电子制冷原理(国外英文资料) Principle of semiconductor electronic refrigeration Application and development of semiconductor refrigeration technology Maqiaoshi This paper systematically expounds the development history and present situation of semiconductor refrigeration technology, introduces its main application in industry, and points out the development trend of semiconductor refrigeration technology Keywords semiconductor refrigeration; thermoelectric material; Perle tie effect; thermocouple; CLC number TP 211.51 Application, and, development, of, semiconductor, refrigerant, technique Ma Qiaoshi (Dept.of, Auto, Control, Shenyang, Arch.and, Civ.Eng.Inst., Shenyang, 110015, China) Abstract, This, paper, summarizes, the, history, and, present, situation, of, semiconductor, refrigerating, introduces, the, application,, in, industry.and, its, development, development, direction. Keywords semiconductor refrigerating; pyroelectric materials; Peltier effect; thermo-electric couplers Semiconductor refrigeration also called thermoelectric refrigeration, from a range of refrigeration technology and semiconductor technology developed in the 50s edge discipline, it uses a special semiconductor P-N junction, the formation of the thermocouple, the Perle post effect, through a new type of DC refrigeration cooling. Compared with the traditional refrigeration technology, it the advantages are: (1) has the advantages of simple structure, no noise, no wear, no pollution and high reliability; (2) cooling speed, flexible control; (3) the thermopile can be arbitrary distribution, size and shape variable. Because of the advantages, now at home and abroad are promoting this technology, 1, 3. This paper introduces and reviews the status quo of semiconductor refrigeration technology development in recent years, for engaged and interested in semiconductor refrigeration technology reference. From the historical point of view the development of semiconductor refrigeration, has experienced three stage
