ALUMINUM FIN FOR CROSS-FIN TUBE-TYPE HEAT EXCHANGER, AND CROSS-FIN TUBE-TYPE HEAT EXCHANGER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an aluminum fin for a cross-fin tube type heat exchanger, and the cross-fin tube type heat exchanger using the same, capable of solving a problem on buckling in bending such as L-bending.

SOLUTION: A plurality of projecting sections are formed near both side faces of a fin of the aluminum fin used in the bent cross-fin tube type heat exchanger. The projecting sections roughly have the oval shape extending in the direction at right angle to the longitudinal direction of the fin in a state of observing the fin from straight above.
