Abstract

The invention discloses a 10kW/2450MHZ package type continuous wave magnetron and a preparation method. The 10kW/2450MHZ package type continuous wave magnetron comprises a magnetron core (1), a magnetic circuit structure (2), a shielding box (3) and a cold water sleeve (4). The continuous wave magnetron disclosed by the invention is novel in the structure, small in volume and big in output power reaching 10KW. The continuous wave magnetron disclosed by the invention has more than 4000 hours of service life, is small in microwave leakage, and high in safety. The preparation method disclosed by the invention has gone through multitude screening tests, has a reasonable technology and is strong in operability. The obtained magnetron is high in sealing, vacuum degree and pressure resistance, and stable in performance, reduces the rate of fire striking, and overcomes the defects of the prior art.

Description

technical field [0001] The invention relates to a magnetron, in particular to a 10kW / 2450MHz packaged continuous wave magnetron and a preparation method thereof. Background technique [0002] With the increasing application of high-power continuous wave magnetrons in miniaturized microwave sources, our existing 2450MHz series magnetrons are non-packaged continuous wave magnetrons, which need to be equipped with large-volume devices such as electromagnets. , which adversely affects the miniaturization of the microwave source and limits the application range of the product. At present, in the 2450MHz frequency band in China, the microwave output power of a single packaged magnetron can only reach 2kW, and the lifespan is only 2000 hours, and the output power and lifespan are very limited. The objects to be heated in industrial production are often bulky. Insufficient microwave power will directly affect the heating effect and seriously restrict the production scale, which is ...
