Abstract

The invention discloses a gyrotron with a compact liquid-cooled structure, which belongs to the technical field of gyrotrons, and includes a waveguide section, a cooling cavity, and a cooling tube sleeved outside the waveguide section, and a partition bar is arranged on the outer wall of the waveguide section to separate the The bar extends axially along the waveguide section and divides the cooling cavity into a first cooling zone and a second cooling zone. The outlet and the liquid outlet are arranged at the same end of the cooling chamber, and the circumferential channel is arranged at the other end of the cooling chamber. The present invention changes the flow path of the cooling liquid by arranging the partition bar and the circumferential channel, and on the premise of avoiding the large-volume dead water area in the cooling chamber, the liquid outlet and the liquid inlet of the cooling chamber can be placed in the cooling chamber. The same end of the cavity, and the overall structure of the waveguide section in the radial direction maintains a compact single-layer structure.

Description

technical field [0001] The invention relates to the technical field of gyrotubes, in particular to gyrotubes provided with a compact liquid cooling structure. Background technique [0002] The gyrotron is an important high-power millimeter-wave and submillimeter-wave vacuum electronic device. Since the 1970s, driven by controlled nuclear fusion, millimeter-wave radar, high-energy physics and industrial applications, it has been used in various fields have achieved significant development. [0003] In the gyrotron system, the resonant cavity and the microwave output section are circular tube-shaped waveguide sections; these waveguide sections need to be cooled during high-power operation. At present, the existing gyrotron mainly has two liquid-cooled structures: [0004] The first is a single-layer liquid-cooled structure, such as figure 1 As shown, it mainly includes a waveguide section with flanges at both ends, a cooling tube sleeved outside the waveguide section, and a...
