Title: Method for manufacturing heat exchanger
Inventor: ISHIKAWA SUMIO
IPC: F28D1/047
Filed: 1989-05-31
Abstract: PURPOSE:To improve an aeration characteristic at a bent portion of a core and further improve an entire radiation characteristic by a method wherein a flat plate-like core is bent and formed in a thickness direction at a part of the flat plate-like core having a circulation resistance between the fins being lower than that of the other position. CONSTITUTION:This heat exchanger is constructed such that a flat plate-like core is formed in advance and this core is bent and formed by a guide member 4. Plate fins at a part B to be bent and formed are plane fins 3 where no lower is formed, and the plate fins at the portion A linearly formed are lowered fins 2. Each of fin pitches is made the same as each other and the fins may constitute the flat plate-like core. In this way, when the core is bent and formed, an aeration resistance at that portions is made smaller than that of the other portion in advance under an assumption of an increased aeration resistance generated at the bent portion, resulting in that the heat exchanger may perform a uniform heat exchanging operation at each of the portions, and thus an entire radiation performance can be improve.
