| Abstract: |
| Water cooled magnets consume tens of megawatts of power, and the cooling problem caused by the extremely high power density of their high field coils is one of the key factors restricting the improvement of magnet performance. This article takes the high field coil of a 35T water-cooled magnet in a steady-state strong magnetic field experimental facility as the research object. Through experiments, key measured parameters under different working conditions are obtained, and based on this, three-dimensional electric thermal fluid multi field coupling simulation calculation of the high field coil is carried out as boundary conditions. The temperature distribution law inside the coil is studied, and the measured average temperature is compared and analyzed with the calculated average temperature to determine the correction coefficient. The space for further improving the magnetic field within the temperature safety margin of the high field coil is studied. |
