Abstract
Disclosed is a solder coating type aluminum flat tube which is used for an automotive heat exchanger, comprising a non-composite fin and a coating flat tube. The lower end of the non-composite fin is connected with the surface layer of the coating flat tube. The upper part of the coating flat tube is provided with coating and is coated through flux solder, and the non-composite fin consists of aluminum foil. The utility model has the beneficial effects: using the mode that the flux solder is coated to the flat tube, not only fin materials are improved to the most common aluminum foil from composite aluminum, at the same time of reducing the spray brazing process of brazing and decreasing the cost greatly, the molding and tooling life of the fin can be increased five times. The surface of brazed heat exchanger is bright and clean, the service life of the heat exchanger is also improved greatly.
Description
Technical field
The utility model relates to heat exchanger technology, relates in particular to a kind of solder-coated formula aluminium flat conduit that is used for automotive heat exchanger.
Background technology
Heat exchanger is as a kind of significant element equipment in the industry such as oil refining, chemical industry, environmental protection, the energy, electric power, usually in the construction in chemical plant, heat exchanger accounts for the 10%-20% of gross investment, heat exchanger commonly used both at home and abroad at present can be divided into tubular type and board-like two big classes substantially, usually, plate-fin heat exchanger is widely used in the heat exchange of gas and gas, and fin-tube type heat exchanger is more is applied to the gas liquid type heat exchange.What the flat tube of automotive heat exchanger and fin adopted at present is brazing mode, and fin is the composite insulating foil of surperficial tape welding material, after the catalysis of 580 ℃ to 615 ℃ process brazing fluxes, with flat tube and fin welding; This kind mode is for generally adopting mode in the industry, but shortcoming is a lot: the molding cutter life-span higher as the fin cost, fin is short, price is high; In addition, the heat exchanger outward appearance after the soldering is coarse, has caused the corrosion resistant decline of heat exchanger and the shortening in service life indirectly.
The utility model content
At above defective, the purpose of this utility model provide a kind of cheap, outward appearance is exquisite, can improve the solder-coated formula aluminium flat conduit that is used for automotive heat exchanger in service life, to overcome the deficiency of existing product.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of solder-coated formula aluminium flat conduit that is used for automotive heat exchanger comprises non-combined type fin and coating type flat tube, and the low side of described non-combined type fin is connected with coating type flat tube top layer; Described coating type flat tube top is provided with coating by the solder flux solder-coated, and described non-combined type fin is made up of aluminium foil.
The beneficial effect that is used for the solder-coated formula aluminium flat conduit of automotive heat exchanger described in the utility model is: adopt the solder flux solder-coated to the flat tube mode, not only fin material is improved to prevailing aluminium foil by composite insulating foil, in the spray pricker technology that has reduced soldering and when significantly reducing cost, the moulding frock life-span of fin can be improved 5 times; Heat exchanger surface after the soldering is bright clean, and the heat exchanger life-span also significantly promotes.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the described structural representation that is used for the solder-coated formula aluminium flat conduit of automotive heat exchanger of the utility model embodiment;
Fig. 2 is existing flat tube configuration schematic diagram of the same type.
Among the figure:
1, non-combined type fin; 2, coating type flat tube; 3, coating; 4, composite insulating foil fin; 5, braze welding type flat tube; 6, scaling powder stratum granulosum.
The specific embodiment
Shown in Fig. 1-2, the solder-coated formula aluminium flat conduit that is used for automotive heat exchanger described in the utility model, comprise non-combined type fin 1 and coating type flat tube 2, the low side of described non-combined type fin 1 is connected with coating type flat tube 2 top layers, described non-combined type fin 1 is made up of aluminium foil, compare the composite insulating foil fin 4 of traditional product, both reduced the spray pricker technology of soldering and when significantly reducing cost, make the moulding frock life-span of fin improve 5 times again; Described coating type flat tube 2 tops are provided with coating 3 and by the solder flux solder-coated, compare the braze welding type flat tube 5 surface welding-assistant stratum granulosums 6 of traditional product, have both guaranteed that heat exchanger surface was bright clean, have prolonged heat exchanger service life again.
