The whole appearance is colored by oxidation, so that metal texture and objects of safety and environmental protection can be well reflected.

Description

A kind of steel-made nickel-plating Ni-P anticorrosion water passage binding aluminum alloy fin radiator

Technical field

The present invention relates to civilian, industrial radiator field, be a kind of with steel plating Ni-P anticorrosion water channel, binding with aluminum alloy fin, different combinations arbitrarily according to calorific requirement, reduce the stock, be a kind of, solve the corrosion difficult problem of radiator with the anticorrosion base material heating installation water conservancy Ni-P coating and base material isolation.

Background technology

The light-duty radiator of China has had bigger development for many years, multiple reason anticorrosion does not have much progress, cause descend service life, at present the most producer of China with the manual application thermohardening lacquer, copper aluminium is compound is anticorrosion, coating generally adopts manual the filling to be coated with, twice application mode and twice high-temperature baking, production efficiency is low, coating and solvent loss are big and coating storage property such thermosetting performance is relatively poor, easily cause the coating uniformity of inner chamber poor on the other hand, causing local holiday phenomenon, is exactly coated coating.Facts have proved that same returning caused corrosion along with the warm sex change energy of aluminium alloy and the adhesiveness of coating descend.To hiding some dangers for the security reliability and the service life of improving radiator, composite copper aluminium radiator is a kind of new product of releasing for the burn into leakage problem that solves Aluminium Radiator of state's inner radiator industry in recent years, this product is owing to adopt copper pipe, Corrosion Protection increases, but copper pipe is wanted expand tube in manufacture process, weld, along with time length, also can produce intergranular, stress corrosion.

Summary of the invention

The purpose of this invention is to provide a kind of steel-made nickel-plating Ni-P anticorrosion water passage binding aluminum alloy fin radiator.

Technical scheme of the present invention is, according to the domestic light-duty radiator present situation of existing market, the present invention will adopt the steel water channel, the anticorrosion water channel of inside and outside chemical Ni-P plating, steel water channel plating Ni-P layer is fit to various heating water quality, makes radiator of the present invention from having solved a corrosion difficult problem in essence.

The invention has the beneficial effects as follows, chemical nickel plating Ni-P has plurality of advantages, be that coat can't be compared, the shape that it is not plated workpiece limits, have all-pervasive, exhaustive careful amorphous state coating, adhesion is good, corrosion resisting property is strong, can reach more than 10 years service life according to detecting, these advantages not only make to be used in its lumen of radiator anticorrosion and become a reality, and reasonably can obtain good adhesion under heat spreader structures technology and the plating mode, corrosion-resistant, long-life, safe and reliable corrosion-resistant coating, main is that complex method does not need expand tube compound, can not produce intergranular, stress and the corrosion that causes.And can obtain than paint coatings, the compound better heat transfer property of copper aluminium and Corrosion Protection.

The specific embodiment

Below in conjunction with accompanying drawing point of the present invention is explained

Fig. 1 is a kind of front view of steel-made nickel-plating Ni-P anticorrosion water passage binding aluminum alloy fin radiator, also is a kind of embodiment of the design's product, is made up of four sheet heat radiators.

Fig. 2 is aluminium radiator fin＜3〉and locking profile＜2 end view drawing, the aluminium radiator fin of Fig. 2 has 2 keeper＜1 〉, 2 locking profile＜2, radiating fin＜3, composite channel＜4 form.

Fig. 3 is plating Ni-P corrosion-resistant steel water channel＜5〉and header tube＜6, connect plug figure＜7, the steel water channel inserts hole＜8, steel water channel＜5〉composite channel＜4 of external diameter size and Fig. 2, header steel pipe welding hole＜8 big or small identical.

Fig. 4 is sheet and sheet coupling, and its outer-diameter threads 10,12 is identical with the screw thread 6 of nut in the connection of Fig. 3, and 11 is movable nut, its screw thread and 10 great circle threads engaged.

Fig. 5 is the cover of upholstery at monolithic fin two ends, its size is identical with the end face of fin Fig. 2, the cover end has louvre＜13〉and connect screw hole＜14 〉, its combinatorial principle mode be with Fig. 3,＜5〉about chemical Ni-P plating etch-proof steel water channel＜5 aluminium radiating fin＜3 of at the uniform velocity inserting Fig. 2 composite channel＜4 in, two pipes insert respectively simultaneously can; Two ends is reserved an amount of steel water channel＜5〉welding access head.To insert steel water channel＜5〉radiator put into the pressure compounding machine, firmly compounding machine makes keeper＜1 of Fig. 2〉narrow down to minimum, to lock profile＜2〉insert keeper＜1 by direction shown in Figure 6 〉, in case make when unclamping the pressure compounding machine aluminium radiating fin of Fig. 2 produce resilience, produce the gap and form thermal resistance, locking profile 2 insertion depth and aluminium radiator fin＜3 height identical, the welding of compound good fin steel water channel＜5〉two ends is inserted the steel pipe that head inserts Fig. 3 inserts hole＜8〉in welding get final product, connecting plug＜7〉weld and the header tube two ends.The cover of upholstery of Fig. 6 is buckled in the two ends of fin, has blocked header, form the monolithic radiator with in attractive in appearance.In Fig. 5 radiator and radiator coupling 10 adopted the hex tool spiral in radiator the same side up and down Fig. 3＜7 in, with another sheet heat radiator with same method with 11 the combination rear screws in Fig. 3＜7 in, with nut alive 12 spirals of Fig. 4 on the silk up and down of fin mouthful＜10, form two radiator groups, the various combination that uses the same method successively according to calorific requirement becomes the radiator group.
