    Abstract: PROBLEM TO BE SOLVED: To stably adhere a prescribed amount of a flux to a brazing area without interposing any substance which becomes unnecessary for the brazing, such as a binder, in supplying the flux to a member for heat exchangers for brazing. SOLUTION: In producing the member for heat exchangers, particles including the flux are sprayed over a surface of a base made of aluminum or its alloy at a temperature lower by at least 30°C than the melting point of the flux so as to cause the particles to collide against the surface at an average speed of ≥100 m/sec and thereby mechanically adhere the particles thereto.

    Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a heat exchanger, and the heat exchanger manufactured by the method, capable of improving brazing property of a core plate and a tube without impairing heat exchanging performance.
    SOLUTION: As the core plate 111 is retracted to the direction to keep an edge portion 111b away from a core portion 120, a linear tip portion of a dispenser 200 can enter deeply to a position indicated by a two-dot chain line in the thickness direction of the core portion 120 as shown in (b). Thus paste brazing filler metal can be applied to a comparatively wide range of a joining part 122b of the core plate 111 and the tube 122 without reducing an installation area of a fin 121.

    Abstract: PROBLEM TO BE SOLVED: To provide a heat exchanger capable of having pressure-proof strength of a header tank with desired magnitude. SOLUTION: In this method for manufacturing the heat exchanger, the header tank 2 is constituted by stacking and brazing a header part forming plate 8, a pipe connecting plate 9 and an intermediate plate 10 with each another. The header part forming plate 8 is formed by a brazing sheet having a brazing material layer on both surfaces. At least one of outer side expansion parts 12A to 12D extending to the longitudinal direction and having an aperture closed by the intermediate plate 10 is formed on the header part forming plate 8. The pipe connecting plate 9 is formed by the brazing sheet having the brazing material layer on both surfaces. The intermediate plate 10 is formed by a metal bare material having no brazing material layer. A brazing material flow acceleration groove 50 is formed on both surfaces of the intermediate plate 10, and all of the plates 8, 9 and 10 are laminated and brazed. COPYRIGHT: (C)2007,JPO&INPIT
