5) the mechanical membrane removal of partition, finned plate；It is using diamond file that upper spacer, lower clapboard and finned plate surface is pre-
The oxidation film of welding surface removes, until leaking out bright metal covering；
6) vacuum diffusion welding；Successively by upper spacer, lower clapboard, left strip of paper used for sealing, right strip of paper used for sealing, preceding strip of paper used for sealing, rear strip of paper used for sealing and finned plate
Assembling, and surface is connected by vacuum diffusion welding, drill after the completion of connection and will be installed into and out of hydraulic fluid port, through end socket, connect
Leakproofness is measured after pipe.
Preferably, vacuum diffusion welding includes pressure process and diffusion welding (DW) process, the pressure process packet in the step 6
It includes under conditions of 500 DEG C, keeps the pressure value for bearing to be not less than 3.5Mpa between the component for needing to weld；The diffusion welding (DW)
Process is included under conditions of 540 DEG C, completes welding between component, and keep the temperature 2-4h.
Preferably, the soaking time is 3.5h.
The utility model has the advantages that
1, for can still generate HNO after chemical membrane removal3The phenomenon that skin covering of the surface, in this product by need chemical membrane removal every
Plate, finned plate are using mechanical membrane removal together, until internal pure metal layer is revealed, at the same time, each strip of paper used for sealing
It is made by mechanical milling, it is ensured that when welding, the face that contacts with each other between component is pure metal surface, can be effective
The weld strength for guaranteeing diffusion welding (DW) solves the problems, such as that conventional diffusion weldering weld strength is lower.
2, traditional vacuum brazing is replaced using vacuum diffusion welding, the cooler of more preferable sealing efficiency can be obtained, and solved
There are a large amount of weld seams in conventional cooler of having determined, improve the heat exchanger efficiency of cooler, and obtain more good production
Product.
