HEADER PIPE FOR REGENERATOR HAVE A GROOVE

摘要

A header pipe for a heat exchange having a groove is provided to reduce a failure rate caused by brazing bonding by allowing molten filler material to smoothly flow to a desired position with a desired amount. A header pipe(200) includes a sub-header pipe, a filler material(300), and an induction groove(214). The header pipe has a groove(213) for the filler material and a tube insertion hole(211). The filler material flows along the circumference of the tube and the tube insertion hole. The filler material is inserted into the filler material groove. The induction groove has a passage so that the filler material smoothly flows between the tube insertion hole and the groove. The induction groove is gradually expanded to the tube insertion hole from the groove.
