Embodiment 1

[0031] The built-in waterway type electron gun body of this embodiment includes a main cavity 1 formed with an installation cavity, and a transition plate 2 correspondingly arranged at the tail end of the main cavity to realize transition connection with the vacuum chamber. The main cavity A water inlet and a water outlet are formed on the outer side of the water inlet and a water outlet, and a water inlet joint 35 and a water outlet joint 36 are correspondingly arranged at the water inlet and the water outlet. There is an end water channel 31 connecting the water channels of the main cavity correspondingly to form a complete circulation flow path. The water injection channel and the end water channel are connected to form a single circulation flow path, which realizes the synchronous cooling of the two components, reduces the internal water jacket structure, and improves the safety of use.

[0032] Wherein, the main cavity can be made of integral stainless steel material, and...

Embodiment 2

[0042] As a specific implementation, the main waterway, end-connection waterway, side waterway, end-connection waterway and water passage are all formed by drilling and plugging. The diameter of the plugging end hole is 12mm larger than that of the corresponding waterway and the plug is connected by welding. For the plugging of the drilled end of the pipeline, except for the remaining water inlet and outlet, other drilled holes must be blocked, and the plugged end hole should be drilled twice, and its diameter is 1 to 2 mm larger than the diameter of the water channel, which is conducive to plugging The plug is installed to prevent the plug from being accidentally inserted into the pipeline and it is difficult to take it out. The gap between the plug and the gun body is welded by argon arc welding. The welding end of the plug is designed with a welding groove. weld. The size of the weld seam formed here is small, the trauma to the whole body is small, and the welding deformati...

Embodiment 3

[0045] A method for cooling the gun body of the built-in waterway type electron gun, comprising the following steps,

[0046] 1) Cooling water enters from the water inlet and enters the first group of side waterways on the electronic shaping side, and the side waterways are collected to the first main waterway through the end-connecting waterway;

[0047] 2) Cooling water enters the end waterway of the transition plate and enters the second main waterway, then passes through the second main waterway corresponding to the second group of side waterways, and the middle waterway enters the third group of side waterways on the other side and then gathers to the first three main roads;

[0048] 3) The third main channel enters the fourth main channel through the other end channel of the transition plate, and then flows out from the water outlet after passing through the fourth group of side channels.

[0049] At the same time, it also includes the step of converging the fourth grou...

Abstract

An electron gun body having a built-in waterway and a cool method are disclosed, the electron gun body having a built-in waterway comprises a main cavity formed with a mounting cavity, and a transition plate correspondingly arranged at the tail end of the main cavity, wherein the outside of the main cavity is formed with a water inlet and a water outlet, a main waterway is formed on the main cavity, and an end waterway correspondingly communicating the main cavity waterway to form a complete single circulation flow path is formed on the transition plate. The invention discards the double-layerwater jacket structure and adopts the structure of an outer-side square and an inner-side circular electron gun body to avoid the dead angle of cooling and improve the cooling effect through the water drawing hole and the circulating water channel connected in series with a certain direction. The structure of outer drill hole is used, the vacuum chamber inside the electron gun body has no weldingseam, avoiding the hidden danger of water leakage. The welding form of small hole plugging has less weld trauma and less thermal stress deformation of electron gun body. The contour of the electron gun body can be processed by secondary mechanical finishing, which can meet the needs of high-precision installation and positioning.

Description

technical field [0001] The invention belongs to the technical field of electron guns, and in particular relates to a built-in waterway type electron gun body and a cooling method. Background technique [0002] Electron gun is a device for generating, accelerating and converging high-energy-density electron beams. Under vacuum conditions, electron beams can be used in many industrial applications such as high-purity metal smelting, refractory metal melting, evaporation coating, and metal alloying. At present, all high-power electron guns use axial scanning electron guns. The functional components that generate electron beams and control the beam shape require a vacuum cavity as a support. The cavity that provides a vacuum environment for the electron gun is the electron gun body. The body of the electron gun involves vacuum, heat transfer, high pressure, etc., especially the design of heat conduction is very important. High temperature will cause structural deformation, which...
