Description
Technical field:
The utility model relates to the engine aluminum alloy oil coolers such as automobile, engineering machinery, steamer, specifically a kind of corrosion protection plate and fin type aluminium oil cooler adopting nano coating technology Corrosion Protection.
Background technique:
Oil cooler is the key components and parts of engine cooling, and early stage oil cooler majority is that stainless steel is made, and along with the requirement of lightweight and energy-saving and emission-reduction improves constantly, stainless steel oil cooler is substituted by aluminium oil cooler fast.
Oil cooler adopts aluminum alloy material all to there is same problem, and that is exactly that corrosion resistance is more much lower than stainless steel.Etching problem is the obstacle that aluminium oil cooler is applied.The corrosion of aluminium oil cooler is divided into internal corrosion and outer corrosion two kinds.
Surface lacquer is a kind of corrosion-resistant solution, but can only be used for preventing outer corrosion, and cannot spray paint in some outside small channels, and painting process is big for environment pollution, the health that affects workman.
Anodic oxidation is also a kind of effective Corrosion prevention scheme, but Problems existing is: for the product using the soldering of Nocolok brazing flux, be difficult to remove because Nocolok brazing flux after soldering remains in surface, prevent anodised reaction, good antiseptic effect can not be obtained.
Summary of the invention:
The purpose of this utility model is to provide the corrosion protection plate and fin type aluminium oil cooler that a kind of cost is low, technological operation convenient, antiseptic property is excellent.
The utility model is achieved in that
A kind of corrosion protection plate and fin type aluminium oil cooler, include joint, chip, be placed in fin between chip, fin isolation is formed oil circuit, water route by chip, and chip, fin brazed connect, and applies one deck nano-paint coating being formed on the fin on surface, water route, chip; Described soldering is vacuum brazing, is connected between fin and chip by Al-Si-Mg solder; Or described soldering is vacuum brazing Nocolok soldering, is connected between fin and chip by Al-Si solder.
The thickness of above-mentioned nano-paint coating is 2-10 microns.
The advantage that the utility model is given prominence to compared to existing technology is:
1, the utility model nano-paint coating can intercept the contact of aggressive medium and aluminum alloy, thus avoids the generation of corrosion of aluminium alloy, significantly can extend product working life under circumstances; Test shows, does not have cated oil cooler will to leak by corrosion failure for 800-1000 hours in salt spray test, and has the oil cooler of nano-paint coating to reach 2000 hours also obviously not corrode;
2, the utility model nano-paint coating can maintain temperature conductivity, has the abilities such as anticorrosion.
Accompanying drawing illustrates:
Fig. 1 is plate-fin structure schematic diagram of the present utility model.
Embodiment:
With specific embodiment, the utility model is further described below, see Fig. 1:
A kind of corrosion protection plate and fin type aluminium oil cooler, include joint 1, chip 2, be placed in fin 3 between chip 2, fin 3 is isolated formation oil circuit 4, water route 5 by chip 2, chip 2, fin 3 brazing, and the fin 3, chip 2 on formation surface, water route 5 apply one deck nano-paint coating.
The thickness of above-mentioned nano-paint coating is 2-10 microns.
Between above-mentioned fin 3 and chip 2, welding is vacuum brazing, employing be roll clad Al-Si-Mg solder, connected by Al-Si-Mg solder between fin 3 and chip 2; Or Nocolok soldering, is linked together after using roll clad Al-Si solder brazing to complete, is connected between fin 3 with chip 2 by Al-Si solder.
Nano-paint coating can adopt the modes such as spraying, immersion, vacuum suction to add required surface to.
Oil cooler of the present utility model can adopt following methods to process:
1, multiple oil circuit fin 3 and chip 2 are alternately stacked to radiating core;
2, Al-Si or the Al-Si-Mg solder of roll clad on chip 2 is used to carry out brazing;
3, corrosion-resistant position as required, liquid nano-paint is coated to surface oil cooler needing apply, put into baking oven and be heated to 150-200 DEG C, be incubated 20-50 minutes, water route interior surface will adhere to the nano-paint coating that a layer thickness is 2-10 microns closely, realizes the isolation between aggressive medium and aluminum alloy material.
Above-described embodiment is only one of preferred embodiment of the present utility model; not limit practical range of the present utility model with this; therefore: all equivalence changes done according to shape of the present utility model, structure, principle, all should be covered by within protection domain of the present utility model.
Claims (2)
1. a corrosion protection plate and fin type aluminium oil cooler, include joint, chip, be placed in fin between chip, fin isolation is formed oil circuit, water route by chip, and chip, fin brazed connect, and it is characterized in that: on the fin, chip on formation surface, water route, apply one deck nano-paint coating; Described soldering is vacuum brazing, is connected between fin and chip by Al-Si-Mg solder; Or described soldering is vacuum brazing Nocolok soldering, is connected between fin and chip by Al-Si solder.
2. a kind of corrosion protection plate and fin type aluminium oil cooler according to claim 1, is characterized in that: the thickness of described nano-paint coating is 2-10 microns.
