摘要： PROBLEM TO BE SOLVED: To improve strength of a heat exchanger while maintaining desired dripping performance by processing contacts of individual fins of superposed heat exchanger units as fins to become one or more points. SOLUTION: After part of a continued fin material corresponding to a fin end is cut, a convexo-concave shape is provided by pressing, and independent fins of the shape bent at upper and lower ends are obtained. Fin lower part end 101L of upper stage of the fin 101 and upper part end 101U of lower stage are crossed at least at one point in the fin shape, and the fins are brought into close contact with each other while preventing engagement of the fins. Then, a heat transfer tube 2 is inserted, several fin blocks are formed, and pipes are bent so that the fins are brought into contact with each other, all the fins are aligned in the same direction in the direction of bending, inserted, and aligned to the tube 2. When the tube 2 is bent, upper and lower fins are brought into contact with each other at two points. Thus, dripping properties and heat exchanger strength can be largely improved.

摘要： PURPOSE:To prevent crack in a collar or flaw on the internal surface of a collar from generating even in the case of using volatile machining oil by ironing the collar twice or more continuously with an ironing punch having ironing parts different in diameters. CONSTITUTION:An ironing process is executed in a 1st ironing part 3, and the sheet thickness is changed from ta to tb, the rising height is changed from ha to hb. In this case the sheet thickness is controlled to be ta>tb, and the rising height is controlled to be ha>hb. The ironing rate is defined as (D-da)/2ta. Next, the ironing process is executed in a 2nd ironing part 4, the sheet thickness is changed from tb to tc, and the rising height is changed from bb to hc. The ironing rate is defined as (D-db)2tn. By continuously executing ironing twice, the of result working the same as that of the ironing rate of (D-db)/2ta is obtained By continuously executing ironing twice while restraining the ironing rate and executing lubrication at the same time, the fin collar is worked without generating the collar crack or flawing the fin collar 1 internal surface even in the case of using the volatile machining oil.
