Fin for heat exchanger, heat exchanger and air conditioner outdoor unit

The utility model discloses a fin for a heat exchanger, the heat exchanger and an air conditioner outdoor unit. At least one heat sink, the radiating fins are connected with the connecting section; one end, far away from the connecting section, of each cooling fin is a windward end; a plurality of turbulent flow holes are formed in at least one cooling fin; wherein the plurality of spoiler holes are formed at intervals in the direction from the windward end to the connecting section, each spoiler hole penetrates through the cooling fin in the thickness direction of the cooling fin, and the distance between every two adjacent spoiler holes is gradually reduced in the direction from the windward end to the connecting section. According to the fin for the heat exchanger, the heat exchange coefficient of the fin is high, and the heat exchange efficiency of the heat exchanger can be improved. 本实用新型公开了一种用于换热器的翅片、换热器及空调室外机，所述翅片包括：连接段；至少一个散热片，所述散热片与所述连接段相连，所述散热片的远离所述连接段的一端为迎风端，至少一个所述散热片上设有多个扰流孔，多个所述扰流孔在从所述迎风端到所述连接段的方
