Zusammenfassung:	A cooling fan (100) for a wind turbine (1) comprises:- a cooling fan motor (110) extending along a longitudinal axis (X) between a drive end (111) and a non-drive end (112),- a motor shroud (120) having a shroud base (121) transversal to the longitudinal axis (X) at the drive end (111) or at the non-drive end (112), and a lateral wall (122) extending from the shroud base (121) towards the non-drive end (112) or the drive end (111), respectively, up to an opening (123) of the motor shroud (120),- a shroud cooling channel (130) comprised between the motor (110) and the motor shroud (120). The shroud cooling channel (130) comprises at least a first portion (131) longitudinally extending from the opening (123) to the shroud base (121) and at least a second return portion (132) extending from the shroud base (121) to the opening (123) .
