Description

technical field [0001] The invention relates to the technical field of cooling of high-power electromagnetic wave generators, in particular to a working fluid contact cooling system of high-power electromagnetic wave generators and a working method thereof. Background technique [0002] Electromagnetic waves are electromagnetic fields that propagate in the form of fluctuations. High-frequency electromagnetic waves can be used for signal enhancement or interference, as well as efficient heating, and can be widely used in radar and microwave transmitters. For example, high-power microwave technology refers to the generation, transmission, measurement and application of microwave signals with an average power above kilowatts or a peak power above hundreds of kilowatts. The traction of commercial and military requirements has prompted microwave devices to work in the high microwave frequency band, up to the millimeter wave frequency band. In order to maintain a certain power ga...
