摘　　要：为解决测试箱在测试大功率X射线源时遇到的散热问题,根据X射线源及测试箱的结构特点、工况要求、损耗功率等,通过热力学理论计算,初步得出了设备的散热方案;又运用有限元仿真,通过Flotherm软件对设备进行热仿真计算再次得出了散热方案。经过对两种方法进行数据对比后发现,理论计算和有限元仿真所得出的散热方案是一致的,均要求测试箱采用强迫通风散热方案。经实际测试证明,该方案顺利解决了测试箱的散热问题。In order to solve the heat dissipation problem encountered in testing of high power X-ray source by the test box, equipment cooling scheme was initially determined through thermodynamics theory calculation. The calculation was based on the structure characteristics of the X-ray source and test box, working condition requirements and loss power, etc. Thermal simulation based on finite element theory was done by using Flotherm software according to the actual condition. Results of theoretical calculation and finite element simulation were consistent with each other according to data comparison, which showed that the forced ventilation cooling scheme must be adopted by the test box. The practical test showed that the design scheme solved the heat dissipation problem of in the test box successfully.
