Description

A kind of aluminium-aluminium composite pipe and radiator for assembled radiator
Technical field
The utility model one is related to a kind of aluminium-aluminium composite pipe for assembled radiator, and it is mainly used in automobile water Case, belong to special aluminium alloy pipeline.
The utility model two is related to a kind of radiator for assembled radiator, and it is used described in the utility model one Aluminium-aluminium composite pipe, it is mainly used in radiator, belongs to auto parts and components part.
Background technology
Automobile water tank radiator plays as the cooling element of automobile engine system in the manufacture of automobile and application field Very important effect, the length in its life-span directly affect the usage experience of user.The water box for car of the present overwhelming majority is all Using aluminum water block, this water tank is in light weight, good heat dissipation effect.But for copper water tank, the anti-corruption of aluminum water block Corrosion is poor, is easier to produce " drill bit " hole of penetrability on aluminum pipe tube wall and produce spot corrosion leakage.
In order to solve the problems, such as that automobile aluminum water block is perishable, the engineers and technicians of this area have made long-term research and development, Most successful is that composite pipe structure is used on welding type water tank.Its specific method:It is by the way of ratio-frequency welding that aluminium-aluminium is compound Tape welding is connected into clad aluminum flat tube.This aluminium flat conduit is typically made up of three-layer composite structure;Outermost is 4 series alloys, such as 4045,4343 are used as the solder of welding type water tank pipe;Intermediate layer is supervisor, using Al-Mn series aluminium alloy;Internal layer is 7072 aluminium Alloy, the alloy are aluminium-zinc line aluminium alloy, contain 1% or so zinc.
The composite three-layer aluminum pipe being welded into, its internal layer are tubing and the contact layer of water tank coolant, are perishable layers.Internal layer Compared with intermediate layer, 7072 aluminium alloys have relatively low electrode potential, and both alloys are in contact, and 7072 aluminium alloys are as sacrifice Anode can provide protection to the aluminium manganese systems aluminium alloy in intermediate layer, internal surface of pipe is produced homogeneous corrosion, avoid point corrosion Occur.
But the composite three-layer aluminum pipe being welded into can not be applied to assembled water tank.For assembled water tank, generally require Tube expansion or expander.Existing high-frequency welding into composite three-layer aluminum pipe, longitudinal seam be present, can produce to expand along weld seam during expander and split Problem.So existing high-frequency welding into composite three-layer aluminum pipe be not suitable for assembled water tank.
To meet the technological requirements such as tube expansion or expander, existing assembled radiator uses common individual layer drawing aluminium always Pipe is as fluid delivery tube.Therefore, existing assembled water tank aluminum pipe Shortcomings in terms of corrosion resistance.
The content of the invention
The purpose of the utility model one is in view of the shortcomings of the prior art, there is provided a kind of for assembled radiator Aluminium-aluminium composite pipe, its purpose to be realized:The technological requirements such as tube expansion or expander can be met, and with good corrosion resistance and added Work.
To achieve the above object, the utility model uses following technical scheme:
A kind of aluminium-aluminium composite pipe for assembled radiator, it is characterised in that:Aluminium-the aluminium composite pipe is by outer tube Formed with inner tube;The outer tube is Al-Mn series aluminium alloy outer tube, and said inner tube is aluminium-zinc line aluminium alloy inner tube;Aluminium-the manganese Line aluminium alloy outer tube and aluminium-zinc line aluminium alloy inner tube faying face are metallurgical binding, and said inner tube is evenly distributed on the inside of outer tube;Institute The thickness for stating aluminium-aluminium composite pipe is 0.2mm~0.4mm;The 60%-95% of the aluminium-aluminium composite pipe thickness is outer tube thickness, institute The remainder for stating aluminium-aluminium composite pipe thickness is interior tube thickness;Aluminium-the aluminium composite pipe is seamless pipe.
As it is of the present utility model it is a kind of improve, the cross sectional shape of the aluminium-aluminium composite pipe be pipe, flat tube, elliptical tube, Single closing waist type pipe or double closing waist type pipes.
The purpose of the utility model two is in view of the shortcomings of the prior art, there is provided a kind of dissipating for assembled radiator Hot device, its purpose to be realized:With good corrosion resistance, and easy to process, stable performance.
To achieve the above object, the utility model uses following technical scheme:
A kind of radiator of assembled radiator, it includes:Left and right hydroecium, the left and right hydroecium opposite side difference It is connected with left and right side plate, it is characterised in that:It is additionally provided with aluminium-aluminium composite pipe described in claim 1 or 2, the left and right hydroecium Between connected by the aluminium-aluminium composite pipe, the aluminium-aluminium composite pipe passes through tube expansion mode and aluminum fin-stock fastens.
The beneficial effects of the utility model:
1st, there is good corrosion resistance.
Different aluminium alloys is respectively adopted in the inner and outer tubes of aluminium-aluminium composite pipe, the electrode potential of inner tube is less than outer tube Electrode potential.For outer tube, inner tube turns into sacrificial anode naturally.Inner tube connects with the liquid in radiator of water tank Touch, under such conditions, the sacrificial anode as inner tube uniformly can corrode in advance under electrochemical reaction, work as inner tube in theory The relatively high outer tube of ability corrosion electrode potential, so, avoids aluminum pipe in a short time along wall thickness direction after corrosion Produce the possibility of penetrability " drill bit " etch pit.The utility model gives certain scope to the thickness of inner and outer pipes, suitably Selection inner and outer pipes thickness, the protecting effect of sacrificial anode can be greatly improved, so as to greatly improve the life-span of tubing.
2nd, good machinability
The utility model provides a kind of new aluminium-aluminium composite pipe.The faying face of inner and outer pipes is seamless for metallurgical binding Pipe, has good mechanical performance, can bear the processing such as the expanded joint of tubing, expander, bend pipe, heading, can be with common aluminum pipe Equally, same processing is born.For the radiator of assembled radiator, using novel aluminum-aluminium composite pipe, it can pass through Mechanical expanding method and aluminum fin-stock fastening, radiator have good corrosion resistance, and easy to process, stable performance.
