The present invention is intended to solve the problem, and provides a kind of vacuum brazing technique flow process of plate wing aluminum alloy radiator, and it pollutes less, product easy cleaning, and its technical scheme adopted is as follows:
A vacuum brazing technique flow process for plate wing aluminum alloy radiator, is characterized in that, the step of the vacuum brazing technique flow process of described plate wing aluminum alloy radiator is followed successively by:
A) raw material prepares: strip of paper used for sealing, fin adopt AA3003 aluminium alloy, and dividing plate adopts 4343/3003/4343 duplex coating aluminium alloy, and side guard plate adopts 4343/3003 single covering grass plantation;
B) clean: surface clean is carried out to unit parts, the greasy dirt, oxide skin etc. of removing material surface;
C) assemble: each unit parts are superposed successively, after closed assembly, puts fixture; ;
D) soldering: the product after closed assembly is put into vacuum brazing furnace brazing, brazing temperature 600-620 DEG C, vacuum (3-5) × 10 -3pa;
E) check: product complete for soldering is put into the compressed air that water passes into 0.25-0.35MPa, and pressurize 2min does not reveal;
F) dry: the water first drying up spreader surface with air cannon, then radiator is sent into chain type drying oven and dry, bake out temperature 70-85 DEG C;
G) clean: the impurity of product surface is removed, keep product surface to clean.
Tool of the present invention has the following advantages: its technological process is simple, the aluminium alloy heat radiator compact conformation produced, good stability, intensity are high, even weld densification, firmly attractive in appearance, good airproof performance, product is not easily corroded, qualification rate is high, is a kind of vacuum brazing technique flow process of producing high strength, high-performance plate wing aluminum alloy radiator.
