Abstract

The invention discloses a 2450-MHz high-power continuous-wave magnetron and a preparation method thereof. The 2450-MHz high-power continuous-wave magnetron comprises an anode cavity combination unit (1), a cathode outgoing line combination unit (2), an output window combination unit (3) connected with the anode cavity combination unit (1), and an output antenna (4) fixed at the anode cavity combination unit (1); the other end of the output antenna (4) is arranged inside the output window combination unit (3); and the anode cavity combination unit (1) is connected with a cavity cooling water inlet-outlet pipe (5). The structure of the provided continuous-wave magnetron is designed reasonably; the power of the magnetron is high and the output power can reach over 30 KW; the service life can reach more than 5000 hours; the microwave leakage is less; and the security performance is high. Besides, according to the preparation method of the continuous-wave magnetron, lots of experiment screening is carried out; and the method has the advantages of reasonable process design and high operability. Moreover, the prepared magnetron with characteristics of high gas tightness, a high vacuum degree, low sparking probability and stable performance enables various defects existing in the prior art to be overcome.

Description

technical field [0001] The invention relates to a magnetron, in particular to a 2450MHz high-power continuous wave magnetron and a preparation method thereof. Background technique [0002] Energy conservation and environmental protection are the basic national policies for sustainable economic development in my country. The energy consumption of my country's six major energy-consuming industries has accounted for 77% of the total industrial energy consumption, of which 5 industries involve heating treatment. Microwave heating is a selective heating method that directly interacts with the material to be heated. It has remarkable characteristics of high efficiency, clean energy and energy saving. Using microwave heating to replace traditional heating in chemical and metallurgical industries can greatly improve energy utilization and achieve energy saving and reduction. row purpose. At present, in the 2450MHz frequency band in China, the microwave output power of a single mag...
