摘　　要：使用X射线电缆测偏仪的电缆挤出机工作温度高达150°C,对电缆测偏仪散热器的温度进行精确控制是保证测偏仪检测性能的重大因素,因此测偏仪散热器传热性能设计对整个测偏仪工作性能有着重要的作用。基于传热学理论和有限元分析方法,采用SolidWorks软件建立了散热器模型,并利用其中的Simulation模块对散热器进行热力学分析。将仿真分析结果和试验数据采集结果进行对比,通过传热学理论分析,得出仿真产生误差的原因、改进途径以及影响散热器效率的一些重要参数。Because the operational temperature of extruders of the cable radiator can be 150 degrees centigrade,it plays important role in controlling the temperature of fans of radiator detectors with X-ray.Based on both heat transfer theory and the finite element method,a method of thermal analysis is presented by modeling and simulating of radiator using SolidWorks.Through analysis of heat transfer theory,the reasons of simulation tolerance and methods of improving the situation can be induced.By comparing the results of between heat transfer theory and experimental tests,some major parameters influencing the efficiency of radiator can be observed.
