Abstract
The utility model provides a novel laminated foil fin device for an automobile evaporator, which comprises a laminated foil fin, wherein the bottom of the laminated foil fin is provided with an outward projecting weld-aid lug, a brazing flat tube is arranged below the laminated foil fin, an outer welding coating is arranged on the outer surface of the brazing flat tube, and the lower layer of the outer welding coating is provided with a welding flux granular layer. The novel laminated foil fin device has the beneficial effects that the weld-aid lug and the outer welding coating are beneficial to stabilizing welding points, and while the braze spraying process of brazing is reduced and the cost is greatly lowered, the life of the fin molding tool can be greatly prolonged; and the device is beneficial to ensuring that the surface of the processed heat exchanger is bright and smooth, and the overall life of the heat exchanger is also prolonged.
Description
Technical field
The utility model relates to heat exchanger technology, relates in particular to a kind of NEW TYPE OF COMPOSITE paper tinsel fin device that is used for automobile evaporator.
Background technology
For existing like product; A lot of all is the version that is employed in welding fin between some flat tubes that are arranged in parallel or the double-deck lamination; Fin wherein is to be formed as wavy aluminium flake, and each crest of fin and trough all will weld with the flat tube or the double-deck lamination of its both sides; What the flat tube of automotive heat exchanger and fin adopted is brazing mode, and fin is the single paper tinsel of surperficial soldered; This kind mode exists a lot of defectives, and for example the cost of fin is higher, the molding cutter life-span of fin short, price is also higher; In addition, the heat exchanger outward appearance after the soldering is coarse, connects very built on the sand, and this has caused the corrosion resistant decline of heat exchanger and the shortening in service life indirectly.Therefore, to above aspect, need reasonably improve prior art.
The utility model content
To above defective, the purpose of the utility model provides a kind of firmly pad, helps reducing cost, outward appearance is neat, can improve the NEW TYPE OF COMPOSITE paper tinsel fin device that is used for automobile evaporator in service life, to overcome the deficiency of existing product.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of NEW TYPE OF COMPOSITE paper tinsel fin device that is used for automobile evaporator comprises the composite insulating foil fin, this composite insulating foil fin be provided with one outwards protrusion help the weldering projection; Said composite insulating foil fin below is provided with the braze welding type flat tube, and this braze welding type flat tube outer surface is provided with one deck welding external coating and this external coating lower floor is provided with the solder soldering fluid stratum granulosum.
The described beneficial effect that is used for the NEW TYPE OF COMPOSITE paper tinsel fin device of automobile evaporator of the utility model is: help weldering projection and welding external coating through setting; Help firm pad; Reduced the spray pricker technology of soldering and when significantly reducing cost, the moulding frock life-span of fin can improve greatly; Heat exchanger surface after helping guaranteeing to process is bright and clean seamless, and the bulk life time of heat exchanger also promotes to some extent.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the said NEW TYPE OF COMPOSITE paper tinsel fin schematic representation of apparatus that is used for automobile evaporator of the utility model embodiment.
Among the figure:
1, composite insulating foil fin; 2, braze welding type flat tube; 3, scaling powder stratum granulosum; 4, help the weldering projection; 5, external coating.
The specific embodiment
As shown in Figure 1; The described NEW TYPE OF COMPOSITE paper tinsel fin device that is used for automobile evaporator of the utility model; Comprise composite insulating foil fin 1; This composite insulating foil fin 1 bottom is provided with helping of an outside protrusion and welds projection 4, and said composite insulating foil fin 1 below is provided with braze welding type flat tube 2, and these braze welding type flat tube 2 outer surfaces are provided with one deck welding external coating 5 and this external coating 5 lower floors are provided with solder soldering fluid stratum granulosum 3; Said composite insulating foil fin 1 bottom helps weldering projection 4 to be welded on the external coating 5 of braze welding type flat tube 2; In the spray pricker technology that has reduced soldering and when significantly reducing cost, the moulding frock life-span of fin can improve greatly.
