摘　　要：针对在核辐射环境下破拆机器人控制器内部芯片散热的问题,通过分析核辐照以及电子器件的散热原理,提出了一种兼顾防核辐照和散热的方法并设计了相应的结构模型。该控制器机箱内部使用TEC(Thermo Electric Cooler)半导体制冷和相变材料蓄热的方法解决控制器在核辐照环境下的散热问题,并利用热仿真软件ANSYS Icepak进行了仿真。经过对比仿真结果,表明在环境温度为55℃时,添加散热方法后,控制器内部最大功耗芯片温度为80.1℃,低于最高许用温度95℃,说明该方法可满足核辐射环境下的工作需求。Aiming at the problem of chip heat dissipation in robot controller under nuclear radiation environment,a method of preventing nuclear radiation and heat dissipation was proposed by analyzing the principle of radiation dissipation of nuclear radiation and electronic devices,and the corresponding structure model was designed.The inside of controller enclosure uses TEC(Thermo Electric Cooler)semiconductor refrigeration and phase change material heat storage method to solve the heat dissipation problem of the controller in the nuclear irradiation environment,and the thermal simulation software Ansys Icepak is used to simulate.The simulation results show that when the ambient temperature is 55℃and the cooling method is added,the temperature of the chip with the most power consumption inside the controller is 80.1℃,which is lower than the maximum allowable temperature of 95℃,indicating that the method can meet the work requirements in the nuclear radiation environment.
