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 disc type aluminium oil cooler that adopts 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 have 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 two kinds of internal corrosion and outer corrosion.
Surface lacquer is a kind of corrosion-resistant solution, but can only be for preventing outer corrosion, and cannot spray paint in some outside small channels, the health that painting process is big for environment pollution, affect workman.
Anodic oxidation is also a kind of effective anticorrosion scheme, but the problem existing is: for the product that uses the soldering of Nocolok brazing flux, because Nocolok brazing flux after soldering remains in surface, be difficult to remove, stoped anodised reaction, can not obtain good antiseptic effect.
Summary of the invention:
The purpose of this utility model is to provide that a kind of cost is low, technological operation is convenient, the excellent corrosion protection disc type aluminium oil cooler of antiseptic property.
The utility model is achieved in that
A kind of corrosion protection disc type aluminium oil cooler, include chip, be placed in the fin between chip, chip forms oil circuit by fin isolation, chip, fin brazed connect, outside the structure forming at fin, chip, be provided with shell, between shell and chip, form water route, at the internal surface of shell that forms water route, apply one deck nano-paint coating on the outer surface of chip.
The thickness of above-mentioned nano-paint coating is 2-10 microns.
Above-mentioned soldering is vacuum brazing or Nocolok soldering.
The utility model compared to existing technology outstanding advantage is:
1, the utility model nano-paint coating can intercept contacting of aggressive medium and aluminum alloy, thereby has avoided the generation of corrosion of aluminium alloy, can significantly extend product working life under various environment; Test shows not have cated oil cooler will to leak by corrosion failure for 800-1000 hours in salt spray test, and have the oil cooler of nano-paint coating to reach 2000 hours also less than obviously corrosion;
2, the utility model nano-paint coating can maintain temperature conductivity, has the abilities such as anticorrosion.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A portion enlarged diagram of Fig. 1.
Embodiment:
With specific embodiment, the utility model is further described below, referring to Fig. 1-2:
A kind of corrosion protection disc type aluminium oil cooler, include chip 1, be placed in the fin 2 between chip 1, chip 1 forms oil circuit 3 by fin 2 isolation, chip 1, fin 2 brazings, outside the structure forming at fin 2, chip 2, be provided with shell 4, between shell 4 and chip 1, form water route 5, at the internal surface of shell 4 in formation water route 5, apply one deck nano-paint coating on the outer surface of chip 1.
The thickness of above-mentioned nano-paint coating is 2-10 microns.
Between above-mentioned chip 1, fin 2, welding is vacuum brazing, employing be the coated Al-Si-Mg solder of rolling, or Nocolok soldering, links together after using the coated Al-Si solder brazing of rolling to complete.
Nano-paint coating can adopt the modes such as spraying, immersion, vacuum suction to add needed surface to.
Oil cooler of the present utility model can adopt following methods to process:
1, a plurality of oil circuit fins 2 and chip 1 are alternately stacked to radiating core;
2, the Al-Si or the Al-Si-Mg solder that use rolling to be coated on chip 1 carry out brazing;
3, corrosion-resistant position as required, liquid nano-paint is coated to the surface that needs coating on oil cooler, put into baking oven and be heated to 150-200 ℃, be incubated 20-50 minutes, it is the nano-paint coating of 2-10 microns that inner surface, water route will be adhered to a layer thickness 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 with this, limit practical range of the present utility model; therefore: all equivalences of doing according to shape of the present utility model, structure, principle change, within all should being covered by protection domain of the present utility model.
Claims (3)
