In figure：1- furnace chambers, 2- cooler cores, 201- oil pockets, 202- center-aisles, 203- water cavities.
Specific embodiment
Be described further below technical scheme, but claimed scope be not limited to it is described.Following realities
The step of be not described in detail in example is applied, is processed using conventional method.
Embodiment
A kind of aluminum plate wing oil, the vacuum brazing technique of water composite cooler, comprise the following steps：
(1) fin shaping, Cleaning of Parts, assembling parts shaping；
(2) core body is put：As shown in figure 1, because 2 points of cooler core is oil pocket 201, water cavity 203, and the He of oil pocket 201
203 liang of chamber thickness structures of water cavity differ greatly, and also have a center-aisle 202, cooler core 2 between oil pocket 201 and water cavity 203
To keep samming more difficult during soldering, in order to improve the soldering uniform temperature of cooler core 2, need to misplace it pendulum in furnace chamber 1

E. 590~600 DEG C are warming up in 10~15min, 20~40min, vacuum ＜ 4.0 × 10 in stove is incubated-3；
F. 620~630 DEG C are warming up in 10~15min, 30~50min, vacuum ＜ 3.0 × 10 in stove is incubated-3)；
G. 610~615 DEG C are cooled in 5~10min, 20~40min, vacuum ＜ 3.0 × 10 in stove is incubated-3)；
H. power-off cooling, is cooled to 600~605 DEG C in 5~10min, is incubated 40~60min, now, product workpiece temperature
Degree reaches 596~600 DEG C, and vacuum brazing is completed.
Compared with conventional vacuum process for soldering, the parameter in the technique has following feature, is favorably improved pricker
Weldquality, improves the braze-welded structure intensity of product：
1st, increased 150-200 DEG C of temperature section.Because the characteristic of aluminum alloy materials is to be susceptible to secondary oxygen at 300 DEG C or so
Change, if directly rising to 300-400 DEG C from room temperature in brazing process, product will be with temperature and raise and volatilize steam, make
Obtain atmosphere humidity in vacuum furnace chamber 1, it is easier to aoxidize, so as to influence the vacuum of vacuum drying oven, influence the vacuum brazing matter of product
Amount.Increasing 150-200 DEG C of temperature section carries out the insulation of a period of time, its role is to product is fully dried, to ensure furnace chamber 1
Interior vacuum, is that good environmental basis are established in the vacuum brazing of product.
2nd, 560-570 DEG C of temperature section, in this section of soaking time, vacuum level requirements 4.0 × 10 are provided with-3.This temperature
Section is exactly that solidus temperature when solder is welded is interval, and solder rupture of membranes needs good vacuum condition, prevents vacuum condition not
The soldering strength of good Product jointing position re-oxidation, influence solder joint quality and product.
3rd, it is provided with 590-600 DEG C of temperature section.Because cooler core 2 is thick and big, the more conventional product of high temperature uniform temperature is poor,
This temperature section just provides powerful guarantee for core body high-temperature samming, beneficial to solder wetting, sprawls and fills, so as to form high-quality
Solder joint.
4th, 620~630 DEG C, 610~615 DEG C, 600~605 DEG C of temperature sections are provided with, are interval brazing temperature.Conventional
Welding temperature is 595 DEG C~605 DEG C, and because the area and volume of cooler are larger, under conventional brazing temperature, cooler is in welding
The insulation samming in area is extremely difficult to the quality requirement of high intensity weld seam, and soaking time is very long, and efficiency is low；620~630
DEG C, 610~615 DEG C, 600~605 DEG C of segmentation insulation welding temperature interval welded, enable to weld seam to have good
Microstructure and weldquality.
