由国家财政专项支持的大型低温制冷设备研制项目29日在河北廊坊通过了国家财政部委托组织的验收。至此,我国已具备制造万瓦级液氢温区制冷设备的能力,从而打破了发达国家在该领域的技术垄断。所谓大型低温制冷设备,是指制冷温度20K(一253℃)及以下,制冷量为数百至万瓦以上,集精密加工、气体轴承氦透平膨胀机技术、低温传热与绝热技术、高效安全集成调控技术
The large-scale cryogenic refrigeration equipment research and development project supported by the state finance department was approved by the Ministry of Finance on the 29th in Langfang, Hebei Province. So far, our country has the ability to manufacture refrigeration equipment with a capacity of 10,000 watts of liquid hydrogen temperature zone, thus breaking the technological monopoly of developed countries in this field. The so-called large-scale low-temperature refrigeration equipment, refers to the refrigeration temperature 20K (a 253 ℃) and below, cooling capacity of hundreds of thousands of watts or more, set precision machining, gas bearing helium turbine expander technology, low temperature heat transfer and thermal insulation technology, efficient Safety integrated control technology
