Title:
高温ろう付け用薄肉ブレージングシートフィン材およびそれを使用した熱交換器の製造方法
Document Type and Number:
Japanese Patent JP5258636
Kind Code:
B2
Abstract:
The present invention provides a thin brazing sheet fin component for high temperature brazing and a method for manufacturing a heat exchanger using the same. According to the invention, the thin brazing sheet fin component with a thickness less than 85 mu m is used. Even the brazing is performed at a high temperature higher than 610 DEG C, the tilting deformation at the end of the fin is not caused. Al-Mn series alloy which is used as a core material is composed of the following components: 0.7-1.5% of Mn, 0.3-0.8% of Si, 0.05-0.75% of Fe, and the balance of Al substantially. The solder which is used for jointing with two surfaces of the core material is Al-Si series alloy with Si content of 5.5-8.0%. Furthermore the average coating rate of a single surface of the solder is 6.0-9.8%. Furthermore the relationship between the silicon content (Sif) in the solder and the average coating rate (CR) of a single surface of the solder is adjusted so that the following formula is satisfied: Q=Sif(mass%)*CR(%)<=67.
