    • A heat exchanger which has i) a fin material comprising a triple-layer clad material constituted of a core material composed of an aluminum alloy containing from 0.5 to 1.8% by weight of Mn and from 0.5 to 3.0% by weight of Zn and, provided on both sides of the core material, a brazing filler material composed of an Al—Si alloy containing from 6.5 to 13.0% by weight of Si and from 0.15 to 0.60% by weight of Cu and ii) an aluminum alloy tube having a Zn concentrated surface; the both having been brazed with each other; wherein, after brazing, recrystallized grains of the core material have an average length of from 100 to 1,000 μm in the lengthwise section of a fin and the recrystallized grains of the core material are 4 or less in average number in the thickness direction of that lengthwise section. This heat exchanger is improved in the durability of fin joints and fins themselves and their strength after corrosion.
    • 一种热交换器,其具有包括由包含0.5〜1.8重量%的Mn和0.5〜3.0重量%的Zn的铝合金构成的芯材构成的三层包覆材料的翅片材料, 在芯材的两侧,由含有6.5〜13.0重量%的Si和0.15〜0.60重量%的Cu的Al-Si合金构成的钎料,以及ii)具有Zn浓缩的铝合金管 表面; 两者相互钎焊; 其中,在钎焊后,芯材的再结晶晶粒在翅片的长度方向上的平均长度为100〜1000μm,芯材的再结晶晶粒的长度方向的平均数为4个以下 部分。 该热交换器改善了翅片接头和翅片本身的耐久性及其腐蚀后的强度。
