Abstract: PROBLEM TO BE SOLVED: To execute flux-brazing without applying a flux agent before assembling by joining at least one 1st component and at least one 2nd component during brazing process to each other. SOLUTION: A brazing sheet is manufactured, after applying a flux 19 to a thin sheet 13, by rolling and coating with a pair of rollers 24. The brazing sheet to which the flux 19 is mechanically stuck like this is used for manufacturing a beat exchanger assembly or the like. The thin sheet 13 possesses the flux 19 on either or both of the internal surface and external surface. In forming the component of the assembly, the brazing sheet is pressed, rolled and cut and is made into a tube, header, side support, fin, or the like. At this time, because the parts have the flux 19 on its internal surface, fluxing work in an assembly shop is unneccessitated.

Abstract: PROBLEM TO BE SOLVED: To improve a degree of freedom of a production by arranging a core material and a sheet having a joining clad and mechanically adhering flux to a sheet to conduct CAB brazing an aluminum brazing assembly with using a single process and with eliminating use of the flux. SOLUTION: In coating flux 19 on a sheet 13, the flux supplied in a flux hopper 22 is applied at a dry state by a general static electricity device or is applied at a wet state by using a carrier. When the flux 19 is rolled/applied on the sheet 13 between a pair of rollers 24 and heated/dried by the hot air from a heat source 26, the carrier of the flux 19 is evaporated, the flux 19 is left on the surface of the sheet 13, the sheet is coiled to a coiling wheel 32. By this method, a brazing sheet adhering the flux 19 can conduct stronger brazing by directly assembling, the flux is not required to apply on an assembly preassembled.
