Cryogenic refrigerator
OpenThe high-pressure pneumatic refrigeration system cooperates with the homogenization system to complete the high-pressure inflation and freezing of the sample, and transfer to the homogenization system for homogenization experimental research and characterization. The whole system solves 17 technical difficulties, including ultra-high pressure special gas aeration and recovery technology, ultra-high pressure and leak rate control technology for special gas systems, low-temperature gas-filled experimental cold box multi-layer structure design and integration technology and sample transfer process. The low temperature state maintains the technology and the like.
