The development of microwave heating technology promotes the improvement of industry quality and efficiency, but the drawbacks of microwave heating, such as uneven heating, prevent its wide application in industry. In this paper, a double‐layer ring tube is proposed for improving the heating uniformity and achieving the target temperature. The gap between the inner and outer tubes is evenly divided into four regions, and the cooling liquid flows through the gap to control the temperature of the heating target placed in the inner tube. Maxwell's equation, heat conduction equation, Navier‐Stokes equation and the mass conservation equation are coupled to simulate the heating process, and the experimental data and simulation data are compared to verify the correctness of the model. Meanwhile, the heating uniformity of structure with or without heating exchanger is compared, and the effect of different fluid velocities, different sizes of the reactor and different dielectric constant of heating target on the heating performance is discussed.

换热器在微波加热下控制均匀加工的动力学模型

微波加热技术的发展促进了工业质量和效率的提高,但是微波加热的缺点,例如加热不均匀,阻碍了其在工业中的广泛应用。本文提出了一种双层环形管,以提高加热均匀性并达到目标温度。内管和外管之间的间隙均匀地分为四个区域,冷却液流过该间隙以控制放置在内管中的加热目标的温度。耦合麦克斯韦方程,热传导方程,纳维尔-斯托克斯方程和质量守恒方程来模拟加热过程,并比较实验数据和模拟数据以验证模型的正确性。同时,
