摘要

微波能量耦合窗口是微波化学反应器的关键部件，它应该尽可能小地反射微波能量以避免烧毁功率源，同时密闭反应腔体以分隔反应物与微波装置。根据多物理场耦合模型，利用有限元方法对耦合窗进行了结构应力计算和设计，分析了微波加热过程中介质耦合窗的受热和热应力特点，得到了对工业应用具有参考价值的结果。提出可以通过设计适宜的介质垫片来降低窗体应力，提高可靠性。

Abstract

The dielectric microwave transmission window is one of the key components used in power couplers for microwave chemical reactors. It should keep low microwave power reflection to avoid burning the power source

and at the same

should airproof the cavity of reactor to separate the reactant from the microwave equipments. Based on multi-physics field model together with finite-element method (FEM)

the mechanical and thermal stress characteristic of the dielectric microwave transmission windows during the processing are calculated. Valuable results for applications in industry are obtained. Finally

a novel gasket made by PTFE is proposed to add on the microwave coupled window design

which can reduce the stress and improve reliability.
