Abstract
A cooling fin, used in a heat-exchanger, which includes a breakable line section extending from one side of the cooling fin plate to a substantially middle portion of the plate in a direction perpendicular to the elongated direction of the plate and a substantially V-shaped notch formed at a portion of the other side of the plate corresponding to the extended end of the breakable line section. The cooling fins are stacked in prescribed numbers to make a cooling fin block. The breakable line section includes a perforated line and is broken when one part of the cooling fin block in the elongated direction is bent against the other part of the block along the breakable line section.
