Description
[technical field]
The present invention relates to heat radiator fitting fields, and in particular to a kind of aluminium alloy cooling tube.
[background technique]
The cooling tube of aluminum product in use will be with corrosive medium (engine cool recirculated water or engine row
The exhaust gas put or hydraulic bending moment oil) contact, it is easy that corrosion failure occurs and leakage is caused to ask product failure etc. in use
Topic.
In addition, needing one layer of fusing point with heat-radiation belt on the outside of the cooling tube of aluminum product, main leaf in mutual soldering and being lower than
Three is brazed at one piece in soldering in after molten by the solder of substrate.Conventional process techniques are outside cooling tube and main leaf
One layer of solder is brushed in side, and the technical matters process is many and diverse, coating is uneven, is also easy to fall off, it is difficult to ensure in high-volume
Quality stability index in the case of large-scale production.
[summary of the invention]
In view of problem above, the present invention is intended to provide a kind of aluminium alloy cooling tube, is able to solve cooling tube in use process
Middle corrosion failure and the problem of cause leakage and quality in high-volume large-scale production is stablized.
The technical scheme adopted by the invention is that:
A kind of aluminium alloy cooling tube, including cooling tube body, anti-corrosion layer and the eutectic welding bed of material；
The cooling tube body is middle way pipe fitting, is made of aluminium alloy；
The anti-corrosion layer is made of pvc material, and is arranged in the cooling tube body internal surface；
The eutectic welding bed of material is covered on the cooling tube body outer surface；The material of the eutectic welding bed of material includes as follows
Component:
Phosphorus 0.005%~0.007%, silver 0.003%~0.005%, germanium 0.001%~0.002%, cerium 0.001%~
0.003%, beryllium 0.02%~0.03%, indium 0.005%~0.008%, nickel 0.001%~0.015%, remaining is tin and zinc,
The ratio of tin and zinc is 3:1~4:1.
Preferably, being connected between the anti-corrosion layer and the cooling tube body by adhesive layer.
Preferably, the adhesive layer is made of polyurethane.
Preferably, the adhesive layer with a thickness of 0.15~0.25mm.
Compared with the existing technology, the invention has the following advantages:
For structure of the invention by the way that the eutectic welding bed of material is arranged in the cooling outer tube layer of aluminium alloy, anti-corrosion layer is arranged in internal layer, is formed
Three layers of compound aluminium product make cooling tube midsole layer protective film, efficiently solve substrate and corrosion failure occurs in use and draws
The problem of leakage makes product failure is played, aluminium radiator product service life is improved, had both reached the corrosion resistant product in inside
Performance requirement, and reached the uniform technique requirement not easily to fall off of outside solder thickness, so that production technology has been obtained pole
Big simplification, while finished product also being made to be able to satisfy the requirement of quality guarantee in 1 year in normal conditions of use.
