Abstract
An intelligent liquid helium-free whole-body magnetic resonance imaging superconducting magnet system, comprising: a vacuum container, provided with a main magnetic field superconducting coil in a radially inner side position therein, and a shielding superconducting coil in a radially outer side position therein, and a heat pipe gas tank is arranged in a vacant area between the main magnetic field superconducting coil and the shielding superconducting coil; a liquid helium reservoir, communicated with a liquid-gas storage tank, and connected with the main magnetic field superconducting coil or the shielding superconducting coil via a helium self-oscillation heat pipe; a refrigerator, fixed on the vacuum container through a thermal conduction component auto-pluggable component; the first thermal conduction component connected with the refrigerator is in close contact with the thermal radiation screen assembly, and the second thermal conduction component connected with the refrigerator is in close contact with the liquid helium reservoir.
