Heat exchanger and method for manufacturing the same |
(57) A heat exchanger (1) includes a header pipe (2, 3) comprising a header pipe body
(6) and connecting portions (13, 14) projecting outwardly from the surface of the
header pipe body (6) and connected to each other at a plane contact condition. A joint
block (16) or a bracket (15) is connected to header pipe (2, 3) so that the joint
block (16) or bracket (15) is brought into contact with both the header pipe body
(6) and one or two connecting portions (13, 14). The joint block (16) or bracket (15)
is precisely positioned relative to header pipe (2, 3), and a good brazing property
therebetween can be achieved.
