摘要
微波加热相对于传统热传导加热具有内外加热的效果,但其在工业应用中存在加热效率低下、加热不均匀等问题。据此,提出一种基于双端口非同步旋转结构的加热方法,降低端口间的互耦;并基于COMSOL Multiphysics建立了双端口旋转下的微波加热模型,分析了双微波源端口之间的旋转速度对端口间的互耦和加热均匀性的影响,实现了端口间低互耦、高均匀性的加热,同时极大提高了微波加热的效率。
Compared to conventional heat conduction heating, microwave heating has the effect of internal and external heating and has been widely used in various fields such as industry and agriculture. Nevertheless, the problems of low heating efficiency and low heating uniformity in industrial applications are still widespread. A heating method based on dual-port non-synchronous rotating structure is proposed to reduce the mutual coupling between ports, and a microwave heating model of dual-port rotating structure is established based on COMSOL multiphysics. This paper analyzes the effect of the rotation speed between the two microwave source ports on the mutual coupling and heating uniformity between the ports, realizes the low mutual coupling and high uniformity heating between the ports, and greatly improves the efficiency of microwave heating.
