摘要： A brazing sheet (1) includes a core material (11) composed of an Al alloy that contains 0.20-3.0 mass % of Mg; and a filler material (12) layered on the core material and composed of an Al alloy that contains Mg, 6.0-13.0 mass % of Si, and more than 0.050 mass % and 1.0 mass % or less of Bi. The Mg concentration of the filler material becomes continuously lower in a direction from a boundary (122) with the core material to an outermost surface (121). The Mg concentration of the filler material is 0.150 mass % or less at a first depth from the outermost surface that is ⅛ of a thickness (tf) of the filler material and is 5-90% of the amount of Mg in the core material at a second depth from the outermost surface that is ⅞ of the thickness of the filler material.

摘要： A fin for a heat exchanger includes a flat portion parallel to a flow direction of a fluid, multiple louvers cut and inclined from the flat portion and arranged in the flow direction, and a fluid-turning part arranged between two of the louvers adjacent to each other to be parallel to the flow direction. The louvers located upstream of the fluid-turning part are opposite from the louvers located downstream of the fluid-turning part in an inclination direction. The louvers include at least first louvers and second louvers. The first louvers are inclined from the flat portion at a first inclined angle larger than a second inclined angle at which the second louvers are inclined from the flat portion. The second louvers are arranged adjacent to the fluid-turning part.

摘要： An aluminum alloy brazing sheet used for brazing of an aluminum material in an inert gas atmosphere or in vacuum is formed of a two-layer material in which a brazing material and a core material are stacked. The core material is formed of an aluminum alloy and has a grain size of 20 to 300 μm, and the aluminum alloy contains Mn of 0.50 to 2.00 mass %, Mg of 0.40 to 2.00 mass %. Si of 1.50 mass % or less, Fe of 1.00 mass % or less, and Ti of 0.10 to 0.30 mass %, with the balance being aluminum and inevitable impurities. The brazing material is formed of an aluminum alloy containing Si of 4.00 to 13.00 mass % with the balance being aluminum and inevitable impurities. In a drop-type fluidity test, a ratio α (α=Ka/Kb) of a fluid coefficient Ka is 0.50 or more.

摘要： A fin for a heat exchanger includes a flat portion having an upstream flat part and a downstream flat part parallel to a flow direction of a fluid. Multiple louvers are arranged in the flow direction. A fluid-turning part including a surface approximately parallel to the flow direction is arranged between two of the multiple louvers. A first portion of the louvers located upstream of the fluid-turning part are inclined in a direction opposite from a second portion of the louvers located downstream of the fluid-turning part. The first and second portion of the louvers include first louvers and second louvers. The first louvers are inclined from the flat portion at a first inclined angle larger than a second inclined angle at which the second louvers are inclined from the flat portion. The second louvers are arranged adjacent to the fluid-turning part.
