基于各向异性材料的低能耗热流控制模块研究

摘要

In order to reduce the energy consumption of heat control unit used in ultra-precision machining system, a low-energy heat control unit was designed based on anisotropy nano composite.In this unit, control flow was accessed through the heat conductor's principle direction, while input flow was accessed through the non-principle direction.Therefore heat conducting circuit was optimized and energy reduction was realized in theory.The unit was modeled using thermal network theory and the model was updated according to experiment data.The influence to the unit's control performance was analyzed by considering some key parameters.Further energy reduction method in control strategy was presented in the end.Experiment results show energy reduction of heat control unit is about 50％.%为改善应用于超精密加工系统的热控制模块能耗大的状况,设计了一种低能耗热流控制模块.模块的导热体基于各向异性纳米复合材料制作,输入热流从导热体非主方向通入,控制热流从主方向通入,从而优化了热流传导路径,机理上实现了低能耗.使用热网络法对模块建模,并依据实验数据对模型进行了修正.最后利用模型分析了关键参数对模块控制性能的影响,并提出了在控制策略中进一步减小能耗的方法.实验结果表明,热控制模块能耗减小在50%左右.
