【摘要】 针对微波加热、微波化学等领域面临的热点驻留、负载失配、可控性差等问题,开展了基于注入牵引技术改善微波加热性能的研究,实现对微波加热均匀性的改善。基于磁控管注入锁定理论与注入牵引特性,拓宽了注入锁定磁控管输出可调范围,并开展了五杯水负载下的微波加热实验。在注入牵引态范围内扫频的方案下,相较于磁控管自由振荡状态,五杯水负载的加热均匀性提升了20%。基于注入牵引技术的微波加热方案为磁控管在微波加热上的应用提供了新思路。更多还原

【Abstract】 A study has been conducted on improving microwave heating performance based on injection pulling technology to address issues such as hot spot retention, load mismatch, and poor controllability in fields such as microwave heating and microwave chemistry, achieving improved microwave heating uniformity. Based on the magnetron’s injection-locking theory and injection-pulling characteristics, an injection-locked magnetron with frequency modulation output was achieved, and microwave heating experiments were conducted under five-cup water loads.Under the scheme of sweeping frequency within the range of injection pulling, the heating uniformity of the five-cup water load improved by 20% compared to the free oscillation state of the magnetron. The injection-pulling technology provides a new idea for applying magnetron in microwave heating.更多还原
