Abstract
The provided surface treatment method for heat-pipe radiator with vacuum copper pipe and aluminum thermal fin comprises: A. before assembly, forming protective layer on surface respectively by electroplating or passivating the copper pipe, oxidizing aluminum fin surface; B. after assembly, taking secondary process for new protective layer. This invention improves product corrosion resistant capacity.
Description
Technical field
The present invention relates to communicate by letter or the heat dissipation technology of electronic applications, be specifically related to a kind of surface treatment method of heat-pipe radiator.
Background technology
Heat-pipe radiator is to assemble with vacuum heat-pipe and aluminium radiator fin that copper tube is made, and its surface treatment generally is: chemical passivation or electroplating processes are carried out in the copper surface, electroplates and adopts electronickelling or electrodeposited chromium or eleetrotinplate usually; Chemical conversion or anodic oxidation treatment are carried out in the aluminium surface.Copper pipe and aluminium flake assemble with welding or riveted way after surface treatment respectively again, after this do not remake other processing treatment.Heat-pipe radiator product corrosion resistance after handling like this is not strong, the junction of copper pipe and aluminium flake is easier to be corroded, and is not suitable for abominable outdoor environment, as areas such as seashore, high industrial pollution, acid rains, if use in these areas, the surface corrosion phenomenon will appear in product in a short time.
Summary of the invention
The present invention is directed to the not strong shortcoming of heat-pipe radiator product corrosion resistance of prior art, a kind of resistance to corrosion of heat-pipe radiator, surface treating process for heat pipe radiator that it can be worked under severe environment steadily in the long term of improving is provided.
Technical scheme provided by the invention is as follows:
A kind of surface treating process for heat pipe radiator, described heat-pipe radiator includes vacuum copper pipe and aluminium radiator fin, comprises step:
A, to before the assembling of described vacuum copper pipe and aluminium radiator fin, respectively described vacuum copper pipe is electroplated or Passivation Treatment, oxide treatment is carried out on the aluminium radiator fin surface, and form protective layer on its surface respectively;
B, after the assembling of described vacuum copper pipe and aluminium radiator fin, the junction of described heat-pipe radiator surface or vacuum copper pipe and aluminium radiator fin is handled again, and forms new protective layer.
Handle on the surface of opposite heat tube scatterer among the described step B, detailed process is: in the whole immersion of heat-pipe radiator paint, the heat-pipe radiator surface is fully contacted with coating, soak the above time in 30 seconds, then heat-pipe radiator is taken out, paint coating is solidified.
Among the described step B junction of vacuum copper pipe and aluminium radiator fin is handled again, detailed process is: the connecting portion of vacuum copper pipe and heat radiation aluminium flake is painted or gluing one by one, and form protective layer.
Handle on the surface of opposite heat tube scatterer among the described step B, and detailed process is: be coated with organic coating on the top layer of heat-pipe radiator or form new protective layer with electrophoresis painted mode.
Handle on the surface of opposite heat tube scatterer among the described step B, and detailed process is: adopt hot dip process metal or thermospray metal to form new protective layer on the surface of heat-pipe radiator.
In the described steps A described vacuum copper pipe is carried out electroplating processes, detailed process is: be that the vacuum copper pipe is carried out multi-layer plating, to form the electrolytic coating of thickening on the surface of vacuum copper pipe.
The invention has the advantages that: by in that handle the surface or the junction of treated heat-pipe radiator again; make the sealer of heat-pipe radiator thicken; increase surperficial organic coating, thereby make that heat-pipe radiator can be at the medium-term and long-term stable corrosion phenomenon that uses, is not easy to occur of abominable outdoor environment.
Description of drawings
Fig. 1 is the structural representation of heat-pipe radiator.
