Summary

Superconducting magnets are typically maintained in a cryogenic environment to sustain their superconducting state. The use of cryocoolers for conductive cooling of these magnets has emerged as a cost-effective and operationally simple cooling trend. However, achieving an efficient heat connection between cryocoolers and low-temperature superconducting magnets has become a key concern. Vibrations and electromagnetic interference from the cold head can impact magnet performance, while the leakage field from high-field magnets can affect cryocooler efficiency. Furthermore, the integration of coolers and cooled objects necessitates efficient heat transfer units for long-distance heat conduction. Pulsating heat pipes have shown remarkable advantages in this aspect.
This study aims to experimentally investigate the heat transfer characteristics of long-distance liquid helium pulsating heat pipes. Specifically, it seeks to explore the relationship between the effective heat transfer coefficient of these heat pipes and the length of heat transfer while providing theoretical explanations.
