【発明の詳細な説明】 〔産業上の利用分野〕 本発明はアルミニューム製熱交換器のブラケットの如
く、熱交換器のサイドメンバやタンク表面に一体的にろ
う付け固定される平板状部品の炉中ろう付け方法に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a flat plate-like component which is integrally brazed and fixed to a side member of a heat exchanger or a tank surface, such as a bracket of an aluminum heat exchanger. It relates to a brazing method in a furnace.
一例としてアルミニューム製熱交換器は、その製作の

いる。そして、各部品を組み立てて高温の炉内に挿入す

却し各部品間を一体的にろう付け固定するものである。As an example, in an aluminum heat exchanger, a brazing sheet having a brazing material clad on the surface is used for at least one of the parts to be joined to each other for manufacturing the heat exchanger. Then, each part is assembled and inserted into a high-temperature furnace. Then, the brazing material on the surface of the component is melted, cooled, and the components are integrally brazed and fixed.
このようなろう付けにおいて特にブラッケット等の平
板状部品は、その部品をプレス機械によって切断した時
その縁部に生ずるバリが接合面と反対側に向くようにし
て他の部品表面に接触させ、両者間をろう付け固定して
いた。これは、バリによって各部品相互間に僅かに隙が
できるのを嫌うためである。In such a brazing, in particular, a flat part such as a bracket is brought into contact with the surface of another part in such a manner that when the part is cut by a press machine, burrs generated at the edge face the opposite side to the joining surface, and The gap was fixed by brazing. This is because it is not desirable to have a slight gap between the components due to burrs.
しかしながら、本発明者の実験によれば従来の板状部
品の如くバリ面をろう付け面と逆側に向けた場合には、
接合面にねじれ等の僅かな傾き及び接合面に対する不均

ろう材８が中央又は一方に寄せられる。このようなろう
付け面はろう付けの剥離強度の弱い欠点があることが本
発明者の実験研究により明らかとなった。However, according to the experiment of the present inventor, when the burr surface is turned to the opposite side to the brazing surface as in a conventional plate-shaped component,
When there is a slight inclination such as torsion on the joint surface and an uneven gap to the joint surface, the molten brazing material is affected by this inclination or the uneven gap and one side is biased, or the brazing material is in the center. It is sent. For example, as shown in FIG. 4, the brazing material 8 is moved to the center or one side. It has been clarified by the inventor's experimental research that such a brazed surface has a disadvantage that the peel strength of brazing is weak.
即ち、ろう付け面のろう材は平面部品の周縁全周に行
き渡らず、一部のみに保持されるため、剥離強度が小さ
るなるのである。これは、溶融したろう材がその表面張
力の影響でより小さな隙間に引き寄せられる結果であ
る。In other words, the brazing material on the brazing surface does not spread over the entire periphery of the flat part, but is held only on a part thereof, so that the peel strength is reduced. This is a result of the molten brazing material being drawn to smaller gaps under the influence of its surface tension.
そこで本発明は以上の問題点を取り除くため次の構成
をとる。Therefore, the present invention employs the following configuration to eliminate the above problems.
