Abstract
An aluminium alloy radiator features that the steel pipe is arranged in the steel-aluminium composite joint, the isolating layer is arranged in the middle and the aluminium plug is arranged outside, and the steel-aluminium composite joint is welded integrally.
Description
The invention relates to radiator, particularly aluminium alloy extrusions welding, steel aluminium composite-joint and whole anodized aluminium alloy heat radiator.
As everyone knows, aluminium alloy heat radiator has numerous superiority, and some documents also have report, yet,, do not have desirable product so far and come out owing to reasons such as sealing, corrosion and combinations, particularly aluminium matter pipe joint combines with the steel water-supply-pipe, and the screw thread wearing and tearing are poorly sealed; The commissure oxide layer is destroyed, very easily by the boiler water corrosion leakage, causes the aluminium alloy heat radiator life-span short, and weak effect is can not become industrialization product and the main cause that is used widely.
The purpose of the invention is at above deficiency, and the steel aluminium composite-joint that contains aluminium matter plug behind a kind of inner core steel tube outer wall separation layer is provided, and whole anodized aluminium alloy heat radiator.
Aluminium alloy heat radiator comprises aluminium alloy communicating pipe 1, aluminum alloy heat sink 2 and steel aluminium composite-joint 4 etc., it is characterized in that steel aluminium composite-joint 4 is steel tube 5 in it, and centre is separation layer 6, and it is an aluminium matter plug 7 outward; After aluminium alloy communicating pipe 1, aluminum alloy heat sink 2 and the welding of steel aluminium composite-joint 4 entire combination, inside and outside containing one deck anodization plated film 8.
The aluminium alloy heat radiator manufacture method is characterized by extrusion modling aluminium alloy communicating pipe 1 and aluminum alloy heat sink 2, and length is blocked in accordance with regulations; Aluminium alloy communicating pipe 1 bottom surface system breach, aluminum alloy heat sink 2 end face millings; External separation layer 6 its outer die casting again of the steel tube 5 of steel aluminium composite-joint 4 or be pressed into aluminium matter plug 7; Steel aluminium composite-joint 4 is solded into aluminium alloy communicating pipe 1 two ends; The aluminium alloy communicating pipe 1 bottom notch place of postwelding is solded into aluminum alloy heat sink 2 end faces; The inside and outside one deck anodization plated film 8 that contains of aluminium alloy heat radiator after the entire combination welding is finished product.
The inventor finds through long-term development tackling key problem, though the various structures of aluminium gold radiator were reported to some extent in the past, but be difficult to become industrialization product and be used widely, exist the difficult point that is difficult to overcome, the first will be with the combination of steel water gas pipe when aluminium alloy heat radiator is used, the wearing and tearing of aluminum screw thread, poorly sealed, and both electrochemical potentialses of direct when contact that do not add separation layer can be accelerated corrosion, promptly leak at that time or later; They are two years old, the aluminium alloy extrusions that dispatches from the factory all passes through anodization, the surface is generally not perishable, and the existing variation of metallographic structure of welding back weld seam, the surface anodization plated film comes off, under the corrosion of boiler water, do not have protective action, promptly leak later, make its life-span low, intensity difference is difficult to satisfy instructions for use.
According to the steel aluminium composite-joint that this method is made, steel pipe is outer can to carry out hot-dip aluminizing, infiltration 10-15 μ mm, and die casting aluminium matter plug is welded on aluminium alloy communicating pipe two ends then again; Aluminium alloy heat radiator inside and outside wall after the entire combination welding carries out the anodization plated film again, surface 8-15 μ mm, inwall comprises that weld seam can play antisepsis, outer wall can play the attractive, decorative effect, needn't carry out applying the second time, integral body has only been carried out anodization one time, and cost is not high yet, and this is that general aluminium alloy heat radiator is difficult to expect or accomplish when making.
The invention theory is feasible, and is reasonable in design, simple in structure, easy to manufacture, easy to use, can effectively avoid the screw thread wearing and tearing, poorly sealed, antiseptic property is poor, defectives such as the life-span is short are corroded through the hot-water boiler water supply quality: hardness 0.12 equivalent parts per million, basicity 4.2 equivalent parts per millions, CL
-144 mg/litre, pH value 8.3-8.4,70 ± 2 ℃ of temperature are incubated after 10 hours and cooled off 10 hours, repeatedly, outward appearance still is silvery white as a result, finds no the red rust point, and corrosion resisting property improves 19.8 times, solved the difficult problem of aluminium alloy heat radiator corrosion, be emerging of aluminium alloy heat radiator, reliable assurance is provided, be suitable for penetration and promotion.
The invention accompanying drawing 1 is the aluminium alloy heat radiator structural representation, and Fig. 2 is steel aluminium composite-joint 4 structural representations, aluminium alloy communicating pipe 1 wherein, aluminum alloy heat sink 2, weld seam 3, steel aluminium composite-joint 4, steel tube 5, separation layer 6, aluminium matter plug 7, anodization plated film 8, anticorrosive film 9.
Embodiment:
Steel aluminium composite-joint is a critical component.Behind the steel tube outer wall mechanism screw thread, hot-dip aluminizing or nickel plating, cadmium plating, separation layers such as zinc-plated or enamel are avoided the directly contact and corroding of steel aluminium, can fill at whole inwall in case of necessity to be coated with the corrosion-resistant film former used or resin of one deck aluminium foil surface hydrophilic, strengthen antiseptic property.
