兰州重离子研究装置分离扇回旋加速器的新型注入器--直线加速器正在设计中。漂移管直线加速器（DTL）的设计目的是将238 U34+从0.140 MeV/u加速到0.97 MeV/u [1]。本文采用三维有限元法对热性能进行了分析。在操作期间，腔将产生焦耳热。由于温度过高，谐振腔将不能正常工作，热变形将导致频率漂移。因此，有必要进行热分析，以确保使用正确的工作温度。分析结果表明，水冷系统进入谐振腔后，谐振腔的温升约为20度，频率漂移约为0.15%。
A linear accelerator as a new injector for the Separated Sector Cyclotron at the Heavy Ion Research Facility of LAN Zhou is being designed. The Drift-Tube-Linac (DTL) has been designed to accelerate 238U34+ from 0.140 MeV/u to 0.97 MeV/u [1]. The 3D finite element analysis of thermal behavior is presented in this paper. During operation, the cavity will produce Joule heat. The cavity will not work normally due to the high temperature and thermal deformation will lead to frequency drift. So it is necessary to perform thermal analysis to ensure the correct working temperature is used. The result of the analysis shows that after the water cooling system is put into the cavity the temperature rise is about 20 degrees and the frequency drift is about 0.15%.
