摘要: 氢能作为清洁能源,已成为世界各国解决能源和环境问题的重要选择,其中终端装备储氢效率成为了氢能在交通领域、能源领域能否大规模利用的关键。针对深冷高压储氢技术研究所需的低温高压复合测试环境,设计并研制了一种深冷高压试验平台,选用液氮作为低温制冷工质,压缩氦气作为增压工质,对三型储氢瓶开展低温工况下的加压、保压和泄压试验,通过舱体数据接口实现远程数据传输和流程控制,保证测试过程安全性。结果表明,该试验平台能够实现快速降温和升压,形成20 MPa/80 K-100 K的低温高压复合环境,同时保压稳定,泄压迅速安全,既可用于低温复合材料的性能测试,也可满足氢能装备研制中对压力、温度循环疲劳测试的需求。该试验平台有助于车用低温系统关键装备的开发与测试,同时也可为相关试验平台的研究提供一定的参考。

Abstract: As a clean energy, hydrogen energy has become an important choice for countries around the world to solve energy and environmental problems. Among them, the efficiency of hydrogen storage in terminal equipment has become the key to whether hydrogen energy can be used on a large scale in the transportation and energy fields. Aiming at the low-temperature and high-pressure composite test environment required for the research of Cryo-compressed hydrogen storage technology, a Cryo-compressed test system was designed and developed. The type III hydrogen storage bottle has carried out pressurization, pressure retention and pressure relief tests under cryogenic conditions, and realizes remote data transmission and process control through the cabin data interface to ensure the safety of the test process. The results show that the test system can achieve rapid temperature drop and pressure increase, forming a Cryo-compressed composite environment of 20MPa/80K-100K, while maintaining stable pressure and releasing pressure quickly and safely. It can not only be used for performance testing of cryogenic composite materials, but also meet the demand for pressure and temperature cycle fatigue testing in the development of hydrogen energy equipment. It helps the development and testing of key equipment for automotive cryogenic systems, and can also provide a reference for the research of related test systems.
