摘要: 针对传统微波炉驻波分布不均引发的加热不匀、能量利用率低等问题,基于人工表面等离激元原理,设计了含H面波导喇叭天线激励装置与金属褶皱慢波结构的新型微波炉。研究确定了激励装置核心设计参数,提出了一种阵列式金属褶皱结构。经仿真验证,该结构在2.45 GHz中心频率下可激励出均匀表面波,腔体内横向电场均匀性宽度达210 mm,纵向高度达150 mm,2.45~2.46 GHz工作频段内反射系数小于-10 dB,空载及不同负载条件下均能实现均匀加热。制作样机实测后,证实该微波炉有效改善了传统微波炉的驻波缺陷,样机能效达52%,加热均匀性与能量利用率表现良好,为新型微波炉的结构设计与性能优化提供了新的方案和实验依据。

Abstract: To address the problems of uneven heating and low energy utilization caused by standing wave distribution in traditional microwave ovens, this paper designs a new type of microwave oven based on the principle of artificial surface plasmon, which contains an H-plane waveguide horn antenna excitation device and a metal fold slow-wave structure. The core design parameters of the excitation device are determined, and an array-type metal fold structure is proposed. Simulation results show that this structure can excite uniform surface waves at a center frequency of 2.45 GHz, with a uniformity width of the transverse electric field of 210 mm and a longitudinal height of 150 mm in the cavity. The reflection coefficient is less than -10 dB in the working frequency band of 2.45~2.46 GHz. Uniform heating can be achieved under no-load and different load conditions. After the prototype was fabricated and tested, it was confirmed that this microwave oven effectively improved the standing wave defect of traditional microwave ovens. The energy efficiency of the prototype reached 52%, and the heating uniformity and energy utilization rate were good, providing a new solution and experimental basis for the structural design and performance optimization of new microwave ovens.

引言

微波技术凭借其高效、便捷的能量传输与转化特性,在民用生活、食品农产品加工、核工业等多个领域得到了广泛应用,成为各领域不可或缺的核心技术之一[1-3]。其中,在微波加热领域,传统微波炉已得到普及,但其腔体内部微波反射易形成驻波场,导致驻波分布不均,进而引发加热不匀,既影响加热效果与食品品质,也降低了能量利用率[4-6]。

针对上述加热难题,当前行业内的解决方案大多集中于模式搅拌器、旋转台、功率输入模式调控或特定频率加热等方式,通过机械运动、参数调整等手段调整微波传播状态,以缓解加热不均问题[4,6-10]。但此类方法仍存在一定的局限性,难以从根本上突破传统腔体驻波调控的固有瓶颈。基于此,本文从全新角度出发,引入表面波加热技术,结合人工表面等离激元(Spoof Surface Plasmons Polaritons, SSPPs)的传播特性,为解决微波加热不均、能量利用率偏低的问题提供新的技术路径[11]。
