Abstract: The structural design of a high heat flux test facility for divertor components of fusion device, including vacuum vessel, vacuum pumping system, manipulator, small-scale water-cooling system, electronic gun operating platform and so on, is carried out. The rationality and reliability of vacuum vessel structure has been verified through Ansys software. The simulation results show that the max temperature of vacuum vessel outer wall is less than 50℃, and the maximum stresses of vacuum vessel and its support are 134.49MPa and 48.76MPa respectively, meeting the allowable stress intensity requirement (3S_m=620MPa).
