The transverse tube (1) and the column tube (2) comprise copper-aluminum combined tubes of an inner layer copper tube of an outer aluminum tube, the inner diameters of the transverse tubes are 20 to 60 mm, the wall thicknesses are 1 to 15 mm, the inner diameter of the column tube (2) is 20 to 60 mm, the thickness of the modified epoxy internal corrosion proof coating layer (4) is 0.02 to 0.1 mm, and the thickness of heat conductivity modified epoxy external coating layer (5) is 0.02 to 0.1 mm. The internal corrosion proof coating layer has good adhesion force, hot water corrosion resistance, heat resistance and steam corrosion resistance, a test rod coated with the internal corrosion proof coating layer dose not burble, and the coating layer is in good condition after the test rod is dipped in alkaline solution with the PH value being equal to 12.5 for 500 h at 95 DEG C; and the utility model can be applied to heat radiators used for heating in large-scale factory buildings and residences.
Description
Technical field
The utility model relates to a kind of copper aluminium combined column tube radiator of interior underseal, can be used for large-sized workshop, heating residential radiator.
Background technology
Existing cast-iron radiator steel, aluminium or the compound radiator of copper aluminium, its weak point be, inner surface is handled without corrosion protection, contacts phenomenon such as oxidation takes place easily, get rusty during use with water, oxygen etc.Facts have proved that this radiator uses 5-8 the disadvantage of leaking, leak gas just to occur.If on material, take measures, thickening copper aluminium thickness, then cost is too high, and is very uneconomical.
Summary of the invention
The technical problems to be solved in the utility model: avoid above-mentioned weak point of the prior art and provide a kind of manufacturing that increases the service life easy, economical in the copper aluminium combined column tube radiator of underseal.
The technical solution adopted in the utility model
1, the copper aluminium combined column tube radiator of underseal in a kind of, by two transverse tubes 1,3～25 column jeckets 2 that communicate with transverse tube 1, four pipe joints 3 two transverse tube 1 terminations, underseal 4 in the modified epoxy of transverse tube 1 and column jecket 2 inner surfaces, thermal conductivity modified epoxy external coating 5 at transverse tube 1 and column jecket 2 outer surfaces is formed, transverse tube 1 and column jecket 2 are by the internal layer copper pipe, the copper aluminum composite pipes of outer aluminum pipe is formed, transverse tube bore 20～60mm, wall thickness 1～15mm, column jecket 2 bores 20～60mm, wall thickness 1～15mm, the thickness of underseal 4 is 0.02～0.1mm in the modified epoxy, and the thickness of thermal conductivity modified epoxy external coating 5 is 0.02～0.1mm.
2, the copper aluminium combined column tube radiator of interior underseal according to claim 1, it is characterized in that transverse tube 1 long 1.2m, bore 25mm, wall thickness 2mm, column jecket 2 totally 10, every long 0.6m, bore 20mm, wall thickness 1.5mm, the thickness of underseal 4 is 0.08mm in the modified epoxy, and the thickness of thermal conductivity modified epoxy external coating 5 is 0.06mm.
The utility model beneficial effect compared with prior art:
1, the copper aluminium combined column tube radiator of interior underseal of the present utility model, can strengthen radiator corrosion protection ability effectively, underseal 4 has good adhesive force, heat-resisting aqueous corrosion, hear resistance, anti-steam corrosion in the modified epoxy, after the underseal coupon soaked 500h in it scribbled in 95 ℃, the alkaline solution of pH=12.5, do not bubble, coating is intact.
2, interior corrosion-proof paint is easy to use, and use cost is lower than increases tubing thickness, cost saving.
Description of drawings
The schematic diagram of the copper aluminium combined column tube radiator of underseal in Fig. 1;
Fig. 2 is the enlarged drawing in A district among Fig. 1.
The specific embodiment
Shown in accompanying drawing 1,2, among the figure: the 1-transverse tube; The 2-column jecket; The 3-pipe joint; Underseal in the 4-modified epoxy; 5-thermal conductivity modified epoxy external coating.
The copper aluminium combined column tube radiator of interior underseal, transverse tube 1 long 1.2m, bore 25mm, wall thickness 2mm, column jecket 2 totally 10, every long 0.6m, bore 20mm, wall thickness 1.5mm, the thickness of underseal 4 is 0.08mm in the modified epoxy, and the thickness of thermal conductivity modified epoxy external coating 5 is 0.06mm.
The copper aluminium combined column tube radiator manufacture process of interior underseal: after radiator is made moulding, corrosion-proof paint in the modified epoxy of inside perfusion some, multi-angle upset radiator, so that coating immerses all radiator inner surfaces, behind baking-curing, form underseal 4 in the remodeling epoxy, then at radiator outer surface spraying thermal conductivity epoxy external coating 5.
The coating that interior underseal 4 is made up of modified epoxy resin, phenolic resins, dimethylbenzene, cyclohexanone, DAA, carboxylic acid dibasic ester, poly-methyl alkyl siloxane solution, γ-methacryloxypropyl trimethoxy silane solution, polyether-modified silicone solution and pigment, filler and forming.
The compound column jecket of copper aluminium adopts commercially available product, and thermal conductivity modified epoxy external coating 5 adopts China Petroleum Group Engineering and Technology Research Institute to sell the spraying of HR-100 radiator special anti-corrosion erosion coating and forms.
The copper aluminium combined column tube radiator performance test of interior underseal shows that radiator satisfies the performance indications of vapours or hot water heating; Radiator inner surface underseal has good adhesive force, heat-resisting aqueous corrosion, hear resistance, anti-steam corrosion, after the underseal coupon soaked 500h in it scribbled in 95 ℃, the alkaline solution of pH=12.5, bubbles, and coating is intact.
