Abstract
One end sides of two sets of pressed-type headers, which have been molded by an existing press, are cut off, respectively, the cut-off portions of thus obtained one-side-cut-off headers are abutted together and are welded to each other, and a nozzle is welded to the position of a welded portion. With this construction, a large header, which is larger than the pressed-type header, can be manufactured, and the use of which permits a large plate-fin type heat exchanger, that can be used at high pressure, to be manufactured.
Claims5
A plate-fin type heat exchanger comprising:
- a core having a plate-fin and side bars interposed between partitions;
- and
- a header welded to said core, said header including a pair of ends that are formed by cutting off press-shaped headers in a direction perpendicular to a longitudinal direction.
