Abstract
The invention discloses a kind of corrosion-resistant cooling fins, the cooling fin heat dissipation capacity is 800-850W, comprising: the zinc film layer of aluminium lithium alloy base and hot-dip outside the aluminium lithium alloy base, the aluminium lithium alloy base uses corrosion-resisting aluminium lithium alloy, the chemical constituent and quality proportioning that the corrosion-resisting aluminium lithium alloy includes are as follows: lithium 12%-15%, copper 1%-4%, nickel 2%-5%, magnesium 0.5%-2.5%, chromium 0.02%-0.08%, manganese 0.01%-0.04%, remaining is aluminium and inevitable impurity.By the above-mentioned means, light weight of the present invention, has good heat dissipation performance and corrosion resistance.
Description
Technical field
The present invention relates to technical field of heat dissipation, more particularly to a kind of corrosion-resistant cooling fin.
Background technique
With the development of society, heating radiator is set as the heat of heating agent capable of being transmitted to a kind of indoor end
It is standby, it has also become indispensable component part in life.
Common heating radiator material is copper and aluminium alloy, and the two respectively has its advantage and disadvantage.The thermal conductivity of copper is good, but price
More expensive, difficulty of processing is higher, and weight is excessive, and thermal capacity is smaller, and easy to oxidize.And fine aluminium is too soft, cannot directly use, all
Be using aluminium alloy enough hardness could be provided, the advantages of aluminium alloy be it is cheap, it is light-weight, but thermal conductivity is just than copper
Want far short of what is expected, there is also defects for corrosion resistance aspect.
Summary of the invention
The present invention solves the technical problem of: in view of the deficiencies of the prior art, provide a kind of corrosion-resistant cooling fin, matter
Amount is light, has good heat dissipation performance and corrosion resistance.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of corrosion-resistant cooling fin, institute are provided
Stating cooling fin heat dissipation capacity is 800-850W comprising: the zinc of aluminium lithium alloy base and hot-dip outside the aluminium lithium alloy base
Film layer, the aluminium lithium alloy base use corrosion-resisting aluminium lithium alloy, the chemical constituent and matter that the corrosion-resisting aluminium lithium alloy includes
Amount proportion are as follows: lithium 12%-15%, copper 1%-4%, nickel 2%-5%, magnesium 0.5%-2.5%, chromium 0.02%-0.08%, manganese 0.01%-0.04%,
Remaining is aluminium and inevitable impurity.
In a preferred embodiment of the present invention, the aluminium lithium alloy base with a thickness of 3-5mm.
In a preferred embodiment of the present invention, the zinc film layer with a thickness of 0.4-0.8mm.
In a preferred embodiment of the present invention, content≤0.02% of the inevitable impurity.
The beneficial effects of the present invention are: the corrosion-resistant cooling fin of the present invention is by corrosion resistance aluminium lithium alloy base and hot-dip
What zinc film layer was constituted, have the characteristics that light weight, thermal diffusivity be good, good corrosion resistance.
Specific embodiment
