High-power circulator shell and high-power circulator

Abstract

The invention relates to the technical field of high-power microwaves and particularly relates to a high-power circulator shell and a high-power circulator. A traditional circulator is changed from manners that multiple parts are welded and longitudinally combined and connected into a pure mechanical machining that an upper cavity and a lower cavity are symmetrically and transversely connected through a flange. The high-power circulator comprises the upper cavity and the lower cavity which are symmetrical with each other, and the high-power circulator is machined once without any welding, so that geometric dimension precision is high, the assembling error is small, the yield of finished products is high, the maintenance is convenient, the manufacturing cost is low, and the operation quality is stable. The high-power circulator is divided into the upper cavity and the lower cavity which are symmetrical with each other, and a rotary ferrite and a heat-dissipation water cooling disc can be directly machined in the upper cavity and the lower cavity, so that a lighting phenomenon caused due to a gap between an original water cooling disc and a main cavity during the passing of microwaves is avoided, and meanwhile, a cooling water path system is relatively simple and effective. The circulator is relatively convenient and rapid to maintain, and the economic benefit is remarkably increased.

Description

technical field [0001] The invention relates to the technical field of microwave power supplies, in particular to a high-power circulator housing and a high-power circulator. Background technique [0002] The microwave power supply is input through three-phase alternating current, and after rectification, it is raised to high-voltage electricity by a transformer. The high-voltage electricity excites the magnetron to generate electrons at high temperature, and forms stable microwave oscillations in the magnetron, that is, microwave energy is generated. Microwave power supplies are widely used in radar systems, food industry, wood processing, rubber industry and other fields. [0003] In practical applications, due to the mismatch of the load, the microwave will be reversely transmitted, affecting the performance of the microwave power supply, and even burning the expensive magnetron. The circulator can make the microwave directional transmission, effectively preventing the m...

AI Technical Summary

Problems solved by technology

[0004] At present, the commonly used processing method for high-power circulator shells is to weld multiple aluminum plates or copper plates. The welding deformation is large and difficult to control. During use, the gyromagnetic ferrite needs to be replaced frequently. Welding process is adopted, and the inside is closed. Therefore, in order to facilitate the replacement of the rotating ferrite in the prior art, the rotating ferrite is pasted on the water cooling plate, and then the rotating ferrite is placed along the axial direction of the hole on the circulator shell. Put it into the circulator shell, and then connect the water-cooled plate to the circulator shell with screws. In the practical application of high-power microwave power supply, the installation gap between the water-cooled plate and the circulator shell will be Sparking occurs, which seriously affects the performance of the microwave power supply. A water cooling device is also connected to the water cooling plate to cool the gyromagnetic ferrite through flowing liquid. However, since the water cooling plate is arranged above the housing, the The water cooling device can only exchange heat with the contact surface of the water cooling plate, and the cooling efficiency of the gyromagnetic ferrite is low
