| Abstract: | The superconducting outsert of 40 T hybrid magnet of steady high magnetic field facility(SHMFF) is cooled with forced flow of supercritical helium at 4.5 K,5×105Pa and 18 g/s,the spiral-coil heat exchanger was chosen to cool the helium to the supercritical mode.Firstly,the thermodynamic analysis of the refrigeration cycle was carried out to obtain the inlet pressure and temperature of spiral-coil heat exchanger in subcooler,then the hierarchic caliber theory was put forward to design and optimize the subcooler based on project’s demand,which could obtain the coiled way and dimension of the spiral-coil heat exchanger.Finally,the dimension of the subcooler was obtained according to the dimension of spiral-coil heat exchanger,liquefied fraction and extractive time of helium. |
