本文主要介绍联邦德国Leybold-Heraeus有限公司的R210型制冷机。这种制冷机具有较高的可靠性,它是基于G-M循环原理工作的。在封闭回路中用氦气作为工作介质。这种制冷机适用于低温恒温器和低温泵,这是因为,它的压缩机和低温冷头是相互分开的,这样压缩机的振动就不会传到低温恒温器的样品盒或低温泵的本体。此外,低温冷头的位置也可以是独立的。并具有冷头和压缩机的结构简单、可靠性高、维护方便等特点。另外,冷头还具有高的“功率密度”。这种制冷机经14000小时的连续运转,制冷量没有减少。
This article focuses on the R210 chiller from Leybold-Heraeus GmbH, Federal Republic of Germany. This refrigerator with high reliability, it is based on the principle of G-M cycle work. Helium is used as the working medium in the closed circuit. This type of refrigerator is suitable for use with cryostats and cryogenic pumps because its compressor and cryogenic coldhead are separated from each other so that compressor vibrations do not reach the cryostat cartridge or cryogenic pump Ontology. In addition, the location of cryogenic cold head can also be independent. And has a cold head and compressor structure is simple, high reliability, easy maintenance and so on. In addition, the cold head also has a high “power density.” This refrigerator by 14,000 hours of continuous operation, the cooling capacity did not decrease.
