PROBLEM TO BE SOLVED: To provide a fin for a heat exchanger showing a high heat transferring effect and a heat exchanger including the fin.SOLUTION: A fin 10 for a heat exchanger comprises: a heat radiating plate 20; a plurality of opening holes 22a, 22b for heat transferring pipes 12 passing through the heat radiating plate 20; a group 3a of the first slits opened toward an air flow 14 and cut and raised only at one main surface 20a of the heat radiating plate 20; a group 3b of the second slits; and a group 3c of the third slits. The group 3b of the second slits and the group 3c of the third slits are arranged between the opening holes 22a, 22b for heat transferring pipes and heights of the adjoining slits 31a to 34a or the like are made different in respect to an advancing direction of an air flow 14 to cause a height of each of the group 3a of slits to the group 3c of slits to be uneven.SELECTED DRAWING: Figure 1 |
