Claims

[Claims for Utility Model Registration] (1) A heat exchanger characterized in that corrugated fins are disposed between cooling tubes arranged at predetermined intervals in close contact with the tubes by at least line contact. (2) The heating device according to claim 1, which is a utility model registered, in which a recess having the same shape as a part of the outer periphery of a cooling tube is formed on the side of the corrugated fin and is brought into close contact with the tube through line contact or surface contact. exchanger. (3) The heat exchanger according to claim 1, wherein the cooling tube has at least two opposing sides in a cross section that are flat and closely attached to the corrugated fins by line contact or surface contact.
