Lateral side cooling structure for drift section of sheet beam klystron

Abstract

The invention discloses a lateral side cooling structure for a drift section of a sheet beam klystron and relates to the microwave technology. The drift section comprises an upper wall of the drift section and a lower wall of the drift section; the upper wall and the lower wall of the drift section are axially provided with square through slots; the square slots in the upper wall and the lower wall are axially and fixedly connected in parallel, so that a through hole is formed between two square slots; an n-shaped lateral plate is respectively arranged on each of the left side and the right side of the drift section, and the two n-shaped lateral plates are open outwards; the external axes of the two n-shaped lateral plates are respectively crossed and fixedly connected with the left side and the right side of the drift section to form a drift section main body; the openings of the n-shaped lateral plates at two sides of the drift section main body are fixedly connected with an internal side of a lateral cold water cover plate; a water path is formed between the lateral cold water cover plate and the lateral plate; the external side of the lateral cold water cover plate is perpendicularly and fixedly connected with two water nozzles; a water path end cover is respectively installed at two ends of the water path formed between the lateral cold water cover plate and the lateral plate, and two end ports of the water path are fixedly connected in a sealing manner. The invention solves the cooling problem of the W-wave band sheet electron beam. When in work, the tube wall has the maximum temperature of 60 DEG C and meets the requirements of the actual project.

Description

technical field [0001] The invention relates to the field of microwave technology, in particular to high-power microwave components, and relates to a side cooling structure of a belt-shaped klystron drift section. Background technique [0002] The new ribbon-shaped injection klystron has great potential to obtain high-power microwave output in the high-frequency band, and has the characteristics of low operating voltage, high gain and efficiency, small size, light weight and compact structure. It is expected to become the future high-energy accelerator and collider, The core device urgently needed for ultra-long-range radar and lightweight high-power microwave weapons. Ribbon injection klystron is a high power microwave device, which needs to be cooled by water cooling device. The tube wall of the W-band strip-shaped injection klystron is very thin, and the magnetic steel is closely attached to the tube wall. If water channels are placed on the upper and lower wide sides, ...
