冷热匹配对微波炉加热效率的影响

Influence on cold and hot matching for heating efficiency of microwave oven

微波炉是一种将电能转化为微波能量进行加热食物的器具。能量转换过程中,磁控管以输出功率的形式将电能转换为微波能量。但由于匹配的原因,磁控管发射微波的输出功率往往偏低。如何提高磁控管的输出功率,提高微波炉的加热效率,有效节约能源意义非常重大。本论文主要就改进微波炉冷、热匹配后提高磁控管的输出功率,进而提高微波炉的加热效率进行研究。

Microwave oven is an appliance for heating food by converting electric energy into microwave energy. The magnetron converts electrical energy to microwave energy by outputting power in the process of energy conversion. But in fact, the microwave output power of magnetron is often low because of matching. It is of great significance important that how to increasing the output power of the magnetron, improving the heating efficiency of microwave oven and then saving energy effectively. This paper is about how to increasing the output power of the magnetron, improving the heating efficiency of microwave oven through making the cold and hot matching of microwave oven better.
