Abstract

The invention discloses a double-layer board with a turbulent flow column structure for cooling and a vacuum electron beam machining method and relates to the technical field of double-layer boards with cooling structures. Double-layer boards with the thickness being 0.1-10 mm are assembled together according to the set gaps; the assembled double-layer boards are conveyed into a vacuum electron beam vacuum chamber and fastened to a working table; vacuumizing is carried out until the vacuum degree is superior to 7*(10-4) Pa; electron beam surface focusing or defocusing is carried out, a machining path and parameters are edited, and the electron beam machining parameters are set to the proper range; according to the preset procedure, electron beam machining of the turbulent flow column structure for cooling between the double-layer boards is carried out on the designated portion, it is ensured that the upper board achieves penetration, and the lower board has a certain penetration depth,and metal molten on the upper board flows down and makes contact with the lower board to form the turbulent flow column structure; and after machining is completed, standing is carried out for 10-30minutes, a vacuum chamber is inflated, and the machined double-layer board is taken out. According to the double-layer board, the characteristic of the large penetration depth of high-vacuum electronbeam machining is utilized, and rapid machining of the turbulent flow column structure for cooling among the double-layer boards with different thicknesses and different gaps can be achieved.

Description

technical field

[0001] The invention relates to the technical field of double-layer plates with a cooling structure, in particular to a double-layer plate with a spoiler column structure for cooling and a vacuum electron beam processing method. Background technique

[0002] Due to its low density, high rigidity, good stability and good heat insulation performance, double-layer panels with cooling structure are widely used in aerospace, transportation, architectural decoration, military defense and other fields.

[0003] At present, there are two commonly used double-layer board structures. One is to prepare double-layer boards by connecting the panels and cores by gluing. Therefore, it is often constrained by the adhesive. The other is to prepare double-layer plates by brazing. The brazing method requires a lot of equipment investment, a long brazing cycle, and high product costs. There are disadvantages such as difficulty in presetting materials and brazing filler metals....
