Description

technical field [0001] The invention relates to a multifunctional helium condensation circulation system. Background technique [0002] Cryogenic systems have a wide range of applications, and their main applications include: nuclear magnetic resonance, superconducting energy storage devices, superconducting transformers, superconducting motors, nuclear fusion, superconducting maglev trains, high-energy physics experiments and accelerators, etc. The operation of the traditional cryogenic system uses liquid helium immersion cooling. Due to the heat leakage of the cryogenic container, the liquid helium evaporates continuously, and the vaporized helium is directly released into the air, causing the liquid level to drop. In order to maintain the operation of the cryogenic system, liquid helium must be continuously added. Helium is not recycled, resulting in high application costs; manual continuous addition of liquid helium is a heavy workload. [0003] Helium resources are lim...

AI Technical Summary

Problems solved by technology

The existing problems are: 1. The system structure is complex, there are many connections, and the cooling efficiency is not high; 2. The helium recovery system is large in size and heavy, making it difficult to move the system; 3. The helium recovery system does not have pressure protection; 4. The helium recovery system is manually operated, and the degree of automation is not high; 5. The helium recovery system is not configured to recover the exhausted helium when the pressure is too high (due to the failure of the cooling equipment and other reasons)
