Description

TECHNICAL FIELD

[0001] The utility model relates to an electronic accelerator, in particular to a titanium window of the electronic accelerator. BACKGROUND

[0002] It is known in the electronic accelerator production and application industry that the titanium window of the electronic accelerator is mainly composed of a grid plate, a titanium film and a pressing frame. The titanium film is attached to the grid plate and connected to the grid plate around the titanium film by the pressing frame. The grid plate is a traditional grid plate, which comprises a rectangular copper plate with longitudinally distributed arc-shaped through slots to form arc-shaped grids between adjacent arc-shaped through slots. The contact area between the arc-shaped grids and the titanium film is small, which results in low heat dissipation efficiency of the traditional grid plate to the titanium film, and the arc-shaped grids on the grid plate are prone to uncertain deformation after being heated, thereby shortening the service life of the titanium window. SUMMARY

[0003] The utility model provides a titanium window of an electronic accelerator, which can improve the heat dissipation efficiency of the grid plate and prolong the service life of the titanium window.

[0004] The above problems of the utility model are solved by the following technical solutions:

[0005] The titanium window of the electronic accelerator comprises a grid plate, a titanium film and a pressing frame. The grid plate comprises a rectangular copper plate, which is characterized by longitudinally distributed arc-shaped through slots in the same direction to form arc-shaped grids in the same direction between adjacent arc-shaped through slots. The titanium film is attached to the arc-shaped grids and connected to the grid plate around the titanium film by the pressing frame. The arc-shaped grids are evenly distributed along the length direction of the grid plate. Vertical connecting ribs are arranged between adjacent arc-shaped grids except for the arc-shaped grids at both ends. The vertical connecting ribs on the same side are arranged in a staggered manner along the transverse direction of the grid plate and located on the same straight line parallel to the long side of the grid plate.

[0006] There are no less than two support ribs on the upper surface of the grid plate between the grid plate at both ends and the adjacent arc-shaped grid, which are longitudinally parallel to the long side of the grid plate and evenly arranged along the transverse direction of the grid plate.

[0007] The arc-shaped grids adjacent to both ends of the grid plate are located on the upper surface of the grid plate and connected as a whole. The heights of the arc-shaped grids adjacent to both ends of the grid plate are lower than those of the other arc-shaped grids and the outer ends of the support ribs, and the upper surface of the inner section of the support rib and the arc-shaped grids adjacent to both ends of the grid plate are smoothly connected in a streamline shape.

[0008] As can be seen from the above technical solutions, the long rectangular copper plate is longitudinally uniformly distributed with arc-shaped through grooves in the same direction, so as to form arc-shaped grids in the same direction between adjacent arc-shaped through grooves. The titanium film is attached to the arc-shaped grids and is connected with the periphery of the grid plate by the pressing frame. The arc-shaped grids are uniformly distributed along the length direction of the grid plate. In addition to the arc-shaped grids at both ends, vertical connecting ribs are arranged between adjacent arc-shaped grids. The adjacent vertical connecting ribs are arranged in a staggered manner along the transverse direction of the grid plate, and the vertical connecting ribs on the same side are located on the same straight line parallel to the long side of the grid plate. The arc-shaped grids have a larger contact area compared with the long strip grids in the background art, which can improve the heat dissipation efficiency of the grid plate. The vertical connecting ribs arranged between adjacent arc-shaped grids can effectively reduce the deformation of the arc-shaped grids on the grid plate and prolong the service life of the titanium window.
