Problems solved by technology
[0006] At present, in the production of VC radiators, multi-temperature zone tunnel furnaces or vacuum furnaces are generally used for welding. Before welding, the products need to be placed manually, which consumes a lot of manpower. It softens after a long time in the furnace at high temperature, low efficiency, high energy consumption, etc.

Embodiment Construction
[0061] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0062] In the first aspect of the present invention, a welding process is provided for the copper mesh of the VC radiator, specifically molecular diffusion welding, which realizes efficient welding of the copper mesh of the VC radiator, greatly shortens the production cycle, reduces production energy consumption, and reduces product manufacturing cost.
[0063] The copper mesh welding process of the VC radiator of the present invention is carried out based on a diffusion welding machine, and the specific steps are:
[0064] Step 1. Prepare the shell plate and copper mesh;
[0065] Step 2. Lay the copper mesh in the groove of the shell plate;
[0066] Step 3. Using a spot welding machine, fix the copper mesh around the copper mesh at more than 2 points in the groove of the shell plate to form a shell plate and copper mesh spot welding assembly...

The invention relates to a diffusion welding machine heating workbench, a copper net welding technology of VC radiators and a copper net automatic welding machine for the VC radiators. Aiming at the welding requirement of copper nets of the VC radiators, the heating workbench can carry out synchronous diffusion welding on the copper nets of the multiple VC radiators at a time, and the requirementfor efficient and reliable welding is met. The welding technology is designed accordingly, the manner of combining spot welding and diffusion welding is adopted, special heating temperature and pressure are set, and the excellent welding quality of the copper nets of the VC radiators is obtained. According to the copper net automatic welding machine for the VC radiators, full-automatic welding andfeeding and discharging of the copper nets of the VC radiators are achieved, and the welding efficiency is greatly improved. The welding technology is simple, the welding contact time is short, and long-time thermal deformation of materials is avoided. Welding quality is good, and welding reliability is high. The welding efficiency is high, automatic welding is adopted, and the welding productionefficiency is greatly improved.
Description
technical field [0001] The invention relates to a copper mesh welding process for a VC radiator and an automatic welding machine based on the process. Background technique [0002] VC (Vapor Chambers), that is, steam chamber, is also called planar heat pipe, vapor chamber, vapor chamber; with the continuous improvement of chip power density, VC has been widely used in the heat dissipation of CPU, NP, ASIC and other large power consumption devices . Although VC can be considered as a planar heat pipe, it still has some core advantages. VC has better temperature uniformity than metal or heat pipes, which can make the surface temperature more uniform (reduce hot spots); secondly, the use of VC radiator can make the heat source and equipment Direct contact between them reduces thermal resistance. [0003] VC radiator adopts vacuum design, hot air circulates more quickly in the copper mesh micro-environment - heat conduction; [0004] Then, the hot air is heated and rises, and...
