A klystron with a small integrated cooling structure

Abstract

The invention provides a klystron with a small integrated cooling structure, comprising: a high-frequency section, a wire package skeleton sleeved on the outer periphery of the high-frequency section, combined with a wire package fixed on the outer wall of the wire package skeleton, and a coil sleeved outside the wire package The sealing ring and the magnetic shield tube sleeved outside the coil sealing ring. By setting the relative positions of each part, an S-shaped cooling liquid channel along the axial direction of the high-frequency section is formed in the first cavity between the high-frequency section and the magnetic screen cylinder. The klystron also includes an electron gun, an electron gun barrel, a collector and a collector barrel, which realize the circulation of the cooling liquid outside the entire klystron and form an integrated cooling structure. The coolant circulation process is long, the one-way circulation is good, and the electron gun, high-frequency band, wire package and collector can be cooled at the same time, the cooling efficiency is high, and the integrated structure is conducive to the miniaturization of the klystron structure; the coolant can play The function of the oil tank facilitates the movement of the klystron and further simplifies the structure of the klystron.

Description

technical field [0001] The invention relates to a small klystron, in particular to an integral cooling structure of the small klystron. Background technique [0002] High-power klystrons are widely used in microwave electronic systems such as radars, accelerators, and medical equipment. For high-power klystrons with a pulse peak power of several megawatts, the applied voltage needs to be tens of kilovolts, or even hundreds of kilovolts. If the withstand voltage of the electron gun is not enough, frequent ignition will directly affect the stability and life of the klystron. At the same time, when the high-power klystron is working normally, the focusing system and the collector will generate a lot of heat. If the generated heat cannot be dissipated in time, the local temperature will gradually rise. When the temperature rises to a certain level, the parts in the tube will be burned out, resulting in the failure of the klystron. Therefore, the withstand voltage of the elect...

Problems solved by technology

This kind of system has large volume, heavy weight, complex cooling system, and the electron gun is immersed in the fuel tank, and the klystron is not easy to move, so its application places are greatly restricted
