Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method of brazing an aluminum alloy heat exchanger eliminating the necessity of specific work and processes and for preventing erosion in a tube even when solder of a tank is made to flow in a tube bending joint part. SOLUTION: When the brazing filler metal of the tank is molten, by maintaining the temperature of a core at a level lower than that of the tank all the time, erosion of the tube is securely prevented even when the brazing filler metal is made to flow from the tank into the tube bending part.
