In high-power microwave industrial application systems, there will be reflections during microwave transmission. Therefore, the Industrial Microwave Water Load are often used in industrial applications to absorb microwaves to protect the microwave source. As a commonly used terminal matching load, the Industrial Microwave Water Load is mainly composed of a waveguide transmission section and a microwave absorption cavity section.
The microwaves transmitted in the waveguide are absorbed by the cooling liquid flowing in the water chamber and converted into heat energy. The greater the power absorbed by the load, the higher the temperature in the absorption cavity, and the faster the cooling liquid temperature rises. The cooling liquid needs to maintain a certain flow to meet the power capacity requirements, otherwise the water load temperature rises too high, and the microwave absorption will deteriorate.
