The invention discloses an intellectualized liquid-
helium-free magnetic
resonance whole-body imaging
superconducting magnet system. The intellectualized liquid-
helium-free magnetic
resonance whole-body imaging
superconducting magnet system comprises a vacuum container, a
helium liquid storage box and a refrigerator, wherein a main
magnetic field superconducting coil is arranged in a radial insidespace of the vacuum container, a shielding
magnetic field superconducting coil is arranged in a radial outside space of the vacuum container, and a
heat pipe air
storage tank is placed in an idle areabetween the main
magnetic field superconducting coil and the shielding magnetic field superconducting coil; the helium
liquid storage box is communicated with a
liquid storage box and air
storage tank, is also connected with the main magnetic field superconducting coil or the shielding magnetic field superconducting coil through a helium self-oscillating
heat pipe, and the helium self-oscillatingheat
pipe is further communicated with the
heat pipe air
storage tank; the refrigerator is fixed to the vacuum container through a cold head automatic
insertion and extraction
assembly; the first-level cold head of the refrigerator is in
close contact with a
thermal radiation screen
assembly, and the second-level cold head of the refrigerator is in
close contact with the helium liquid storage box. By means of the intellectualized liquid-helium-free magnetic
resonance whole-body imaging
superconducting magnet system, the problems are solved that an existing superconducting
magnet system is poor in cooling performance, once the refrigerator stops work, a
magnet loses heat quickly due to excessive
heat leakage, and the superconducting
magnet system is complicated to maintain and poor in reliability.
