The current mainstream technical approach employs a "GM refrigeration system + multi-stage thermal barrier" configuration: The primary cooling stage (approximately 40K) drives high-temperature thermal barriers to block radiant heat from ambient temperatures. The secondary cooling stage (4.2K) maintains the PTMS MAGNETIC SEPARATOR magnet below its superconducting critical temperature through direct thermal coupling between high-purity oxygen-free copper rods and superconducting coils.
4K/1.5W The GM refrigeration system, featuring an innovative structure combining magnetic thermal storage materials with rare earth permanent magnets, achieves 60% higher PTMS MAGNETIC SEPARATOR efficiency than traditional models and has maintained continuous operation for 100,000 hours without failures. The pulse tube refrigeration unit delivers 1W cooling power in the 4.2K temperature range, reaching internationally leading cooling efficiency levels. This breakthrough provides crucial support for domestic production of liquid helium-free magnet technologies.
The disruptive transformation of the cost structure has made liquid helium-free PTMS MAGNETIC SEPARATOR commercially viable. While the initial manufacturing costs for liquid helium-free magnets are 30-50% higher than traditional liquid helium variants—primarily due to investments in high-precision refrigeration systems, low-leakage vacuum dewars, and sophisticated temperature control mechanisms—their lifecycle cost advantages remain remarkably significant.
