Embodiment Construction

[0031] like figure 1 shown. A device for brazing a brass waveguide and a water-cooled plate with a high bonding rate in a vacuum state. Brazing solder is arranged on the brazed tube wall area of ​​the brass waveguide 13 to be brazed, and the water-cooled plate 10 is fixed on the brass waveguide 13 to be brazed. The area of ​​the waveguide 13 to be brazed constitutes the workpiece, the brazing solder is held together by the water-cooled plate 10 and the brass waveguide 13, a vacuum container 1 is set, and the workpiece is placed in the vacuum container 1 as a whole;

[0032] The vacuum container 1 is provided with a plurality of sections of heating elements 9 surrounding the workpiece. The heating elements 9 are close to but not in contact with the workpiece. A multi-layer shielding assembly 8 is respectively arranged between each section of the heating element 9 and the inner wall of the vacuum container 1 at the corresponding position. The vacuum container Corresponding to t...

Abstract

The invention discloses a device and method for brazing a brass waveguide and a water-cooled plate with a high bonding rate in a vacuum state, brazing the brass waveguide and the water-cooled plate in a vacuum container, and bonding the welded water-cooled plate and the waveguide The combination rate is better than 70%, and there is no oxidation or peeling on the inner and outer walls of the waveguide.

Description

technical field [0001] The invention relates to the field of brazing of a waveguide and a water-cooled plate, in particular to a device and method for brazing a brass waveguide and a water-cooled plate with a high bonding rate in a vacuum state. Background technique [0002] A waveguide is a structure used to confine or guide electromagnetic waves. Generally, waveguides refer to hollow metal waveguides and surface waveguides of various shapes. The former completely confines the transmitted electromagnetic wave in the metal tube, also known as a closed waveguide; the latter confines the guided electromagnetic wave around the waveguide structure, also known as open waveguide. When the radio wave frequency is increased to the centimeter wave band and the millimeter wave band of 3000 MHz to 300 GHz, the use of coaxial lines is limited and metal waveguides or other wave guiding devices are used. The advantage of the waveguide is that the conductor loss and dielectric loss are ...
