斯特林制冷机成功研制填补了国内空白
发布日期：2024-02-07
中轴网记者2月24日获得最新消息，我国首台气体轴承斯特林制冷机工程化产品的成功研制，填补了国内空白。且该项目综合性能指标达到国际先进水平，环境适应性能也达到国际领先水平。
据中轴网了解，斯特林制冷机，是以氦气为工质，在封闭系统中应用回热原理实现气体制冷循环以获得低温和冷量的机械。气体轴承斯特林制冷机是相同制冷量下效率最高、重量最轻、寿命最长的低温制冷机，可为军事探测用超导接收机、通讯基站、低温生物冰箱、制氧/氮机等军民领域提供冷源。目前，只有美国等极少数国家掌握其核心技术。
该所自主研发的斯特林制冷机，具有冷量质量比大、制冷效率高、寿命长和环境适应性强等特性，近日已顺利通过省科技成果鉴定。作为国内唯一的低温与超导专业研究院所，中国电科16所的技术团队潜心攻关6年，突破了静压气体轴承设计与制造、多臂板簧减振器、高效直线电机、冷端高效换热等多项关键技术，先后完成性能样机、产品设计定型、工程化设计优化各阶段工作，产品在总参某部、甘肃浩元、兰州雨生等用户设备上装机使用验证，不仅完全达到国外同类产品的性能指标，更是完成国外同类产品无法保证的高低温、振动、冲击等各项环境适应性测试。
目前，该产品已授权相关发明专利2项，另有5项发明专利已经受理；授权实用新型专利7项，制定标准1项。
