Specific embodiment
Car aluminum radiator as shown in Figure 1 includes water chamber A, cooling fin 4, heat-dissipating pipe 3 and main leaf 1, and heat-dissipating pipe
3, main leaf 1 and cooling fin 4 constitute core, since heat-dissipating pipe 3 and main leaf 1 are directly contacted and used with the coolant liquid in aluminium radiator
Aluminum or aluminum alloy material, and be easy to cause corrosion impact radiator to heat-dissipating pipe 3 and main leaf 1 containing a large amount of iron ions in coolant liquid
Physical life, the program are improved mainly for the Anticorrosion of heat-dissipating pipe 3 and main leaf 1.
The General layout Plan of the core are as follows:
The aluminum radiator core body includes main leaf 1, and the material of the main leaf 1 is aluminum or aluminum alloy, is contacted in main leaf 1 with coolant liquid
Side is equipped with anticorrosive board 2, and anticorrosive board 2 and main leaf 1 directly or indirectly connect, and aperture or makes anti-corrosion on anticorrosive board 2
Gap is reserved between plate 2 and main leaf 1 can guarantee that coolant liquid passes into heat-dissipating pipe 3, and the material of anticorrosive board 2 is that magnesium or magnesium close
Gold, the lower anticorrosive board 2 of potential will occur oxidation reaction as cathode and consume, protected heat-dissipating pipe 3 and main leaf 1 be aluminium or
Aluminium alloy can be to avoid corrosion as anode.
Principle is as follows: finding after detecting to anti-icing fluid inside the aluminium radiator corroded, the concentration of iron and ferriferous oxide
Very high, analysis is the discovery that the electrochemical corrosion of aluminium and aluminium alloy has occurred in the core of aluminium radiator.Analytic process parsing is as follows:
In the cooling system of vehicle, due to containing Fe3+With Fe2+(there are also a small amount of copper ion Cu2+) solution participation under due to metal
Activity (galvanic series relative position) determines and electrochemical reaction (corrosion) has occurred with aluminium and aluminium alloy, and then negative electron is from Al
(aluminium) atom loses, by the high Fe of potential3+It absorbs, Al atom, which loses electronics, becomes Al3+(trivalent aluminium ion), and Fe3+、Fe2+
It absorbs electronics and is then changed into Fe atom, it is anode, Fe that Al atom, which loses negative electron,3+、Fe2+Obtaining electronics is cathode, electrochemistry
Reaction is formed, and embodying just becomes electrochemical corrosion.
By common elements activity sequence list it is found that Mg (magnesium) and Mg (magnesium) alloy can be used as anode and form galvanic anode protection
It defends the doctrine and protects Al atom.Riveting or other modes connection magnesium plate or magnesium on the core of the water inlet position of aluminium radiator assembly
Alloy sheets constitute primary battery with being connected by protection aluminum or aluminum alloy using the lower magnesium plate of potential or magnesium alloy plate as protection pole,
The lower magnesium plate of potential or magnesium alloy plate will occur oxidation reaction as cathode and consume, and protected aluminum or aluminum alloy is as just
It pole can be to avoid corrosion.Caused by effectively solving because of electrochemical corrosion phenomena such as material failure, perforation, etch pit, significantly improve
The service life and quality of aluminum radiator core body.
Specific mounting structure is explained by taking several embodiments once as an example:
Embodiment 1
Main leaf 1 as shown in Figure 2 is equipped with mounting hole 1-1 for installing heat-dissipating pipe 3, and anticorrosive board 2 is laid on main leaf 1,
Anticorrosive board 2 is corresponded equipped with one group of through-hole 2-2, through-hole 2-2 and mounting hole 1-1, protrudes into master by heat-dissipating pipe when installation
Part in piece 1 sets flange and fixes anticorrosive board 2 (with the form of riveting), and it is good both to have can guarantee that anticorrosive board 2 was contacted with main leaf 1 in this way
It is good to can ensure that coolant liquid is able to enter heat-dissipating pipe 3 again.
Embodiment 2
2 both ends of anticorrosive board are fastened on main leaf 1 as indicated at 3, and anticorrosive board 2 is stuck in 1 width direction of main leaf in the embodiment,
Arching upward among anticorrosive board 2, which makes to reserve gap between anticorrosive board 2 and main leaf 1, enters heat-dissipating pipe for cooling liquid stream is logical, in order to make to cool down
The liquid stream general character is more preferably additionally provided with one group of aperture 2-1 on anticorrosive board 2.
Embodiment 3
It is fixed in the heat-dissipating pipe 3 that 2 both ends of anticorrosive board insertion as shown in Figure 4 is mounted in mounting hole 1-1, make in the embodiment
Arching upward among anticorrosive board 2, which makes to reserve gap between anticorrosive board 2 and main leaf 1, enters heat-dissipating pipe for cooling liquid stream is logical, in this case
It is unsmooth that two heat-dissipating pipes 3 of fixed anticorrosive board 2 may result in circulation, but has no effect on the integral heat sink effect of radiator,
Simultaneously anticorrosive board 2 be in this case with 1 mediate contact of main leaf, since the material of heat-dissipating pipe is also closed using aluminium or aluminium
Gold, so that the anticorrosive board plays the role of corrosion-resistant to main leaf main body 1 and heat-dissipating pipe.In order to make circulation more preferably in the embodiment
In anticorrosive board 2 on to be also provided with one group of aperture 2-1 logical for cooling liquid stream.
Anticorrosive board 2 only need to be arranged one section in main leaf (core) main body 1 and can not need to cover comprehensively in above embodiments
Entire main leaf main body 1, covering mainboard main body 1 is also feasible comprehensively for selection certainly.
Certain this programme is not limited to above-mentioned mount scheme, the specific mount scheme being derived according to General layout Plan
Also belong to the protection scope of the program.
