Description

Technical Field

[0001] This invention belongs to the field of magnetron technology, and in particular relates to a high-power continuous wave magnetron. Background Technology

[0002] High-power continuous wave magnetrons require insulating ceramics to withstand high voltages during operation. Traditional straight-cylinder insulating ceramics require high-quality raw materials and advanced molding processes to achieve high voltage withstand levels. Furthermore, consistent magnetron assembly is crucial for product quality stability; minimizing unnecessary manual assembly is essential for maintaining consistency. Statistical analysis shows that most magnetron lifespan ends due to filament performance degradation. When a tube reaches its expected lifespan, only the filament assembly needs replacement to extend its lifespan; however, repositioning the filament assembly during replacement is currently difficult. The cooling effect of the water system in a high-power continuous wave magnetron significantly impacts its lifespan and safety. Differences in water system structure greatly affect the magnetron's cooling effect and the user's facilities and equipment. A well-designed water system not only provides effective cooling but also reduces the need for complex water supply equipment. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A high-power continuous wave magnetron includes an insulating ceramic assembly and a filament assembly and an anode assembly respectively disposed at both ends of the insulating ceramic assembly. An output assembly is connected to one side of the anode assembly. The output assembly includes an output window connected to the anode assembly and an output antenna disposed within the output window. The insulating ceramic assembly includes a head connection and a tail connection, with a non-straight-walled insulating ceramic part between the head connection and the tail connection. The filament assembly is connected to the head connection, and the anode assembly is connected to the tail connection. The output antenna includes a cylindrical end and a round cap end. The cylindrical end is provided with several sets of antenna feet on the side away from the round cap end. The angle between each antenna foot and the center line of the cylindrical end is denoted as α, where α is 50-70°. The anode assembly is also equipped with a water system; the water system consists of several sets of anode blades, which are evenly distributed along the circumference of the anode assembly, and the anode blades are equipped with cooling water channels for cooling.

[0004] Furthermore, the outer surface of the insulating ceramic part is corrugated.

[0005] Furthermore, the cooling water circuit is equipped with a water connector, and the water connector and the surface corresponding to the cooling water circuit are both provided with spiral patterns, through which the cooling water flows out.

[0006] Furthermore, the head connector is provided with a first step, and the filament assembly is provided with a second step that matches the first step.

[0007] Furthermore, the cooling water circuit includes an inlet and an outlet, and the water connector is located between the inlet and the outlet.

[0008] The beneficial effects of this utility model are: 1. The core part of the insulating ceramic assembly in this utility model is made of corrugated ceramic. Compared with straight cylindrical ceramic of the same height, this corrugated ceramic has a longer creepage distance and can withstand higher voltage.

[0009] 2. The sector-shaped structure of the anode and the lead wire connector of this utility model are also manufactured in one piece. This integrated manufacturing reduces assembly manpower and welding frequency, and also ensures product consistency. The filament connector and cathode connector are assembled using a stepped positioning method, which facilitates later assembly and repair of the tube.

[0010] 3. This utility model optimizes the water circuit design. The water connector and the corresponding surface of the cooling water circuit are provided with spiral patterns. The cooling water flows out through the spiral patterns, which greatly reduces the cooling effect of the pipe. Attached Figure Description
