一种采用吸附式压缩机的低温制冷机几乎没有磨损和振动。当发展完善时,这种制冷机不需要电能,它可长时间自动操作,用于冷却灵敏度高的红外探测器,使用寿命估计在十年以上。在实验室实验时,该制冷机在118K产生0.5瓦冷量,其温度可低达100K。此低温制冷机用活性炭交替吸附和解吸氮气。当活性炭被冷却时,它就自然地吸附氮气。当对活性炭加热时,它就放出高压氮 A cryogenic refrigerator with an adsorption compressor has almost no wear and vibration. When developed, the refrigerator does not require power, it can be a long time automatic operation, for cooling sensitive infrared detectors, the service life is estimated at more than a decade. In laboratory experiments, the chiller generates 0.5 watts of cold at 118K and can reach temperatures as low as 100K. This cryogenic refrigerator uses activated carbon to alternately adsorb and desorb nitrogen. When the activated carbon is cooled, it naturally adsorbs nitrogen. When the activated carbon heating, it emit high pressure nitrogen
