PROBLEM TO BE SOLVED: To provide a heat exchanger fin capable of providing a more excellent heat exchange performance.SOLUTION: Four louver groups 22A and 22B composed of a plurality of louvers 21A and 21B are provided in a tabular part 18 of a heat exchanger fin 16 at a spacing in a ventilation direction and flow change parts 23 and 24 for changing wind directions are provided between the adjoining louver groups 22A and 22B. The flow change parts 23 and 24 are composed of: the residual part 18a of a tabular part 18; and windward louvers 25 and 26 and leeward side narrow louvers 27 and 28 disposed in the windward edge part of the residual part 18a. The inclination angles of the windward narrow louvers 25 and 26 of the flow change parts 23 and 24 and the leeward side narrow louvers 27 and 28 with respect to the tabular part 18 disposed at the windward side edge part and the leeward side edge part of the residual part 18a are made larger than the inclination angles of the louver groups 22A and 22B disposed adjacent to the windward side and the leeward side with respect to the tabular part 18 of the louvers 21A and 21B.SELECTED DRAWING: Figure 2
【課題】より優れた熱交換性能を得ることができる熱交換器用フィンを提供する。【解決手段】熱交換器用フィン16の平板状部18に、複数のルーバ21A,21Bからなる4つのルーバ群22A,22Bを通風方向に間隔をおいて設け、隣り合うルーバ群22A,22Bどうしの間に風の流れを変える流れ変更部23,24を設ける。流れ変更部23,24は、平板状部18の残存部分18aと、残存部分18aの風上側縁部および風下側縁部に設けられた風上側幅狭ルーバ25,26および風下側幅狭ルーバ27,28とよりなる。流れ変更部23,24の風上側幅狭ルーバ25,26および風下側幅狭ルーバ27,28の平板状部18に対する傾斜角度が、流れ変更部23,24の風上側および風下側に隣接して設けられたルーバ群22A,22Bのルーバ21A,21Bの平板状部18に対する傾斜角度よりも大きくなっている。【選択図】図2
