Title: Heat exchanger and method of manufacturing the same
Inventor: KAWACHI NORIHIDE
IPC: F28D9/00
Filed: 2001-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a heat exchanger which can suppress the cost of manufacturing and improve the quality of brazing by simplifying the assembly of water tubes 221 and a method of manufacturing the same. SOLUTION: The water tubes are brazed by using phosphorus copper solder of 3±1% in the content of the phosphorus in a brazing filler metal B. The material cost of the brazing filler metal B can be reduced by lowering the content of the phosphorus in the brazing filler metal B. The working of the material of the brazing filler metal B can be easily performed to a thin sheet form by the enhanced ductility of the brazing filler metal B and therefore the cost of working is suppressed and in addition, the brazing filler metal can be used by stretching the brazing filler metal to a foil form thinner than the thin sheet form, by which the consumption of the brazing filler metal B is reduced and consequently the cost of the brazing filler metal can be reduced.  The occurrence of crack by the enhanced ductility is substantially prevented and such thing that the defect in brazing results from wedging of the cracked splinters during assembly and the occurrence of the float in joint surfaces can be prevented.
