半导体制冷技术是利用半导体材料,通过直流电后有致冷能力的特性而发展的。它有别于现今使用的制冷机械原理,不使用制冷剂、没有压缩机、没有运动部件和管路系统。故无噪音、无振动、不污染环境,外形体积小、重量轻,可随身携带,维护方便,使用寿命长。 半导体技术制冷量可从毫瓦级到千瓦级,制冷温差可达30～150°C;改变电压,可实现 Semiconductor refrigeration technology is the use of semiconductor materials, through the DC after the development of refrigeration capacity characteristics. It is different from the principles of refrigeration machinery used today, does not use refrigerant, no compressor, no moving parts and piping systems. Therefore, no noise, no vibration, no pollution to the environment, small size, light weight, portable, easy maintenance, long service life. Semiconductor technology cooling capacity from milliwatts to kilowatts, cooling temperature difference of up to 30 ~ 150 ° C; change the voltage can be achieved
