Method of manufacturing a motorcycle radiator

摘要

A method of manufacturing a motorcycle radiator comprising the steps of: (1) arranging between a pair of horizontally arranged water tanks or headers, a straight radiator core comprising in combination: a plurality of corrugated sheets spaced alternately with a plurality of flattened tubes; the flattened tubes; and elongated reinforcing plates, each of said reinforcing plates being provided with a plurality of slits extending from opposite edge portions in width directions of the reinforcing plates, the slits on one of the opposite longitudinal edge portions being disposed in a row and at a predetermined pitch, and the slits on the other of the opposite longitudinal edge portions being disposed in another row and at the predetermined pitch at respective positions halfway between positions of adjacent ones of the slits on the one of the edge portions with respect to a direction parallel to the longitudinal axis; (11) assembling and brazing these main components to produce a straight radiator which establishes the integrity in its construction; and (111) bending the straight radiator in a direction perpendicular to a longitudinal direction of the flattened tubes so as to produce an arc-shaped radiator.
