接合方法に係るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention has a protrusion having a substantially constant height at the joining point of opposing aluminum alloy members, and a core between the protrusion of the opposing member and the protrusion of the member. This method relates to a joining method for aluminum alloy members, in which a composite brazing sheet having brazing material on both sides of the material is interposed, and the members are joined by increasing the temperature while applying pressure in the direction of the composite brazing sheet. .

度の接合が得られ難いという欠点がある。 The conventional method for joining aluminum alloy members is the fifth method.
As shown in the figure, this method involves interposing the composite brazing sheet 14 between the flat joining surfaces of the members 12 and the flat joining surfaces of the members 12.
The larger the bonding area, the more difficult it is to destroy the oxide film on the bonding surface, and the more difficult it is for gases adsorbed on the bonding surface to come out, making it difficult to obtain a bond with stable strength.

The purpose of this is to act like a hole to expel adsorbed gas from the bonding surface, thereby achieving stable bonding strength.

芯材の両面にロウ材を有する、いわゆる複合ブレ
ージングシートを介在する。 In the method for joining aluminum alloy members of the present invention, a protrusion having a substantially constant height is provided at the location where each of the opposing members is to be joined, and an aluminum alloy core is provided between the opposing members. A so-called composite brazing sheet, which has brazing material on both sides, is interposed.

関係は接合した際に部材の突起と突起との間の谷
部に複合ブレージングシートのロウ材で埋まる程
度になる関係が望ましく、具体的には第２図のよ
うな形状の突起では次のような関係である。 The relationship between the protrusions of this member and the composite brazing sheet is preferably such that when they are joined, the brazing material of the composite brazing sheet fills the valley between the protrusions of the member, and specifically, as shown in Figure 2. For a protrusion shaped like this, the relationship is as follows.
０＜t1≦2t2 t1は突起の高さ、t2はロウ材の厚さ。 0<t 1 ≦2t 2 t 1 is the height of the protrusion, and t 2 is the thickness of the brazing material.
この部材の突起は第２図のように規則的に有し
てもよいが、不規則的に有しているものでもよ
い。また部材の突起の形状は第２図のような形状
や第３図第４図々示のような形状そしてその他の
形状でもよい。 The protrusions of this member may be formed regularly as shown in FIG. 2, but they may also be formed irregularly. Further, the shape of the protrusion of the member may be the shape as shown in FIG. 2, the shape as shown in FIG. 3, FIG. 4, or other shapes.
第４図々示のような形状の突起３″を有する部
材２″と複合ブレージングシートとの関係は次の
ようであることが望ましい。 It is desirable that the relationship between the member 2'' having the protrusion 3'' shaped as shown in FIG. 4 and the composite brazing sheet is as follows.
０＜t′1≦t′2 t′1は突起の高さ、t′2はロウ材の厚さ。 0<t' 1 ≦t' 2 t' 1 is the height of the protrusion, and t' 2 is the thickness of the brazing material.

り込んでいく。即ち部材２の突起３はロウ材６へ
と入り込むし、ロウ材６は部材２の突起３と隣り
の突起３との間の谷部へと入り込んでいく。 As shown in Figure 1, the tips of the protrusions break the oxide film of the brazing material by increasing the temperature while applying pressure in the direction in which the composite brazing sheet 4 exists, that is, in the direction of the arrow. The protrusion 3 of the member 2 and the brazing material 6 of the composite brazing sheet 4 penetrate into each other while also destroying the oxide film at the tip. That is, the protrusion 3 of the member 2 enters into the brazing material 6, and the brazing material 6 enters into the valley between the protrusion 3 of the member 2 and the adjacent protrusion 3.
部材２の突起３がロウ材６へと入り込んでいく

の役割を果すとともに次第に抜け孔が小さくなる
ので前記の酸化皮膜破壊などにより遊離した吸着

のアルミニウム合金の表面を浄化する。 When the protrusion 3 of the member 2 enters the brazing material 6, the valley between the protrusion 3 and the adjacent protrusion 3 acts as a hole and the hole gradually becomes smaller, causing the oxide film to break as described above. This makes it easier to expel free adsorbed gas and other gases, thereby purifying the surface of the aluminum alloy at the joint.
更にこの発明のアルミニウム合金部材の接合方
法では部材の接合すべき個所に突起を有するため
に部材の接合個所の表面積が従来の平らな接合面
のものに較べて大きくなる。 Furthermore, in the method for joining aluminum alloy members of the present invention, since the parts to be joined have protrusions, the surface area of the parts to be joined is larger than that of conventional flat joining surfaces.

定した強度で、より強く接合することができる方
法である。 As described above, the method for joining aluminum alloy members of this invention has protrusions on the parts to be joined, so the surface area is large, and the temperature is increased while applying pressure in the direction of the composite brazing sheet, which destroys the oxide film. In this method, gases such as adsorbed gases are expelled, and the protrusions of the member and the brazing material of the composite brazing sheet penetrate into each other and join, resulting in a stronger joint with stable strength.
