Stress analysis and design of dielectric microwave transmission window for microwave chemical reactors
摘要
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.关键词
