Abstract
The braze welding of 6063 aluminum alloy uses traditional Nooclock non-corrosive braze agent protecting the channel cold plate, adding a layer of pure aluminum or 3A21 aluminum alloy into the welding seam. It is low in cost, high in efficiency, simple in process with low operation requirement.
Description
Technical field
The present invention relates to a kind of slice welding process method of 6063 aluminium alloy microchannel cold plates.
Background technology
Microchannel cold plates is that the minim channel by 0.1～0.6mm constitutes, but material is that intensity is higher, 6063 aluminium alloys of the high soldering of thermal conductivity, needs to adopt method for welding to be welded into the cavity of a sealing, is a kind of high efficiency heat radiation cool plate.
According to the brazing characteristics of 6063 aluminium alloys, be suitable for adopting the vacuum aluminium soldering.But adopt the vacuum aluminium soldering to have such problem,, in brazing process, be easy to flow into the microchannel, thereby stop up the microchannel, influence the heat dispersion of cold drawing near the solder in the weld seam of microchannel because the vacuum brazing of 6063 aluminium alloys is good.
Summary of the invention
The slice welding process method that the purpose of this invention is to provide a kind of 6063 aluminium alloy microchannel cold plates, it can prevent effectively that solder from flowing into the microchannel.
The object of the present invention is achieved like this: adopt traditional Noclock brazing flux without corrosion slice welder skill, it is characterized in that: in the weld seam of microchannel cold plates, add one deck fine aluminium or 3A21 aluminium alloy.During soldering, because the effect of fine aluminium or 3A21 aluminium alloy, can form solder joint comparatively fine and close, that satisfy the air-tightness requirement, and, can prevent effectively that the solder in the weld seam from flowing into the microchannel because the spreadability and the wetability of the weldering of 6063 aluminium alloy Noclock brazing flux without corrosion slices are relatively poor.
The present invention is owing to adopt the weldering of Noclock brazing flux without corrosion slice, and production cost is low, the production efficiency height, and technology is comparatively simple; Because the solder wetting of 6063 aluminium alloy Noclock brazing flux without corrosion slices weldering is relatively poor, be easy in brazing process prevent that solder from flowing into the microchannel simultaneously, process structure requires lower, strong operability.
Description of drawings
Fig. 1, be typical microchannel water-cooled cold drawing structural representation;
Fig. 2, be the vertical view (not adding the cold drawing cover plate) of Fig. 1.
Among the figure: the 1st, the cold drawing cover plate; The 2nd, the cold drawing base plate; The 3rd, minim channel; The 4th, the interchannel dividing plate plays booster action simultaneously, must weld with cover plate 1.
The specific embodiment
Below in conjunction with drawings and Examples, describe process for soldering in detail according to the weldering of the cold employing in 6063 aluminium alloy microchannels of the present invention Noclock brazing flux without corrosion slice.
A) the 3A21 aluminum alloy materials that adopts 0.3mm is as the soldering transition material in the solder joint, the Al-Si eutectic solder of 0.1mm.
B) clean part to be welded and transition material, solder, and on face of weld and transition material, solder surface brush the Noclock brazing flux without corrosion.
C) on weld seam step around the base plate 2, reach the dividing plate end, state ready solder, transition material, solder by putting successively, cover cover plate 1 again, the weld jig of packing into.
D) furnace temperature is risen to 640～650 ℃, open bell, workpiece in the anchor clamps of packing into is hung in the stove, build bell, vacuumize, vacuum feeds high pure nitrogen during less than 0.1Pa to malleation, open fan, continue heating, evenly heat up, be incubated 2～3 minutes until 605～615 ℃, open bell, hang out the workpiece air cooling.
