摘要： The present invention provides a heat exchanger which is assembled by brazing an aluminum fin material to the outer surface of an aluminum tube material formed by bending a sheet material, in particular, an aluminum heat exchanger which can be suitably used as an automotive heat exchanger such as a condenser or evaporator. The tube material is formed of a two-layer clad sheet which includes a core material and an Al—Zn alloy layer clad on the core material. The Al—Zn alloy layer is clad on the outer surface of the tube material and brazed to the aluminum fin material. The potential of the Al—Zn alloy layer in normal corrosive solution is 100 mV or more lower than the potential of the core material in the normal corrosive solution. The potential of the Al—Zn alloy layer in the normal corrosive solution is lower than the potential of the core material in high-concentration corrosive water. The normal corrosive solution refers to an aqueous solution containing 10 g/l of NaCl and 0.3 g/l of Na2SO4, and the high-concentration corrosive water refers to an aqueous solution in which the NaCl concentration is increased by 30 times by concentrating the above aqueous solution.

摘要： An object of the present invention is to provide a filler metal for an aluminum brazing sheet for heat exchangers capable of preventing or controlling occurrence of a melting hole during heating for brazing, and a method of manufacturing the same. In an Al—Si alloy filler metal which is clad on the aluminum brazing sheet and melted during heating for brazing, the maximum particle diameter of a coarse Si particle crystallized in the eutectic structure of the filler metal is 20 μm or less. Provided that an average value and a standard deviation in a normal distribution of the particle diameter of the coarse Si particle in the filler metal are respectively μ and σ, (μ+3σ) is preferably 10 μm or less. This brazing sheet is obtained by a method of adding a specific amount of Na, Sr, or Sb to the filler metal, a method of limiting the amount of impurities in the filler metal within a specific range, a method of specifying a cooling rate during the casting of the filler metal, or the like.

摘要： A sheet material for the tube 10 includes: a core material 10b; and a sacrifical corrosion material 10c clad on one face of the core material 10b which becomes an outside of the tube 10. A sheet material for the fin is a bare aluminum material on which a brazing filler metal is not clad. A mixture composition 10e, in which powder of a brazing filler metal and flux are mixed with each other, is coated on the outside of the tube 10. The tube 10 and the fin are brazed to each other with this mixture composition 10e. Even after the completion of brazing, the sacrifical corrosion material 10c remains on the outside of the tube 10.
