热电制冷是根据十九世纪初期发现的热电效应工作的。当时由于局限于使用热电性能较差的金属材料,效率很低,所以除了利用金属热电偶测量温度外,热电效应在工程技术上没有多少实际应用。直到本世纪五十年代出现碲化铋、碲化锑等半导体材料之后,热电制冷技术才逐渐进入实用阶段。热电制冷有其独特的优点。目前在微型和小型的制冷器件及恒温设备中已经胜过其他型式的制冷机,使用较多。可以深信,随着半导体材料性能的不断提高,制造和焊接工艺的不断改善,它必然会得到越来越广泛的应用。
Thermoelectric refrigeration is based on the thermoelectric effects found in the early nineteenth century. At that time, due to the limited use of metal materials with poor thermoelectric properties, the efficiency is very low, so in addition to the use of metal thermocouple temperature measurement, the thermoelectric effect in engineering and technology is not much practical. Until the fifties of this century appear bismuth telluride, antimony telluride and other semiconductor materials, the thermoelectric cooling technology was gradually into the practical stage. Thermoelectric cooling has its own unique advantages. Currently in the miniature and small refrigeration devices and thermostats have been better than other types of refrigerators, the use of more. Can be convinced that with the continuous improvement of the performance of semiconductor materials, manufacturing and welding technology continues to improve, it is bound to get more and more widely used.
