Cooling fan

A cooling fan (1) for cooling an electronic device (2) is disclosed. The cooling fan (1) comprises a heat sink (5) thermally connectable to the electronic device (2), the heat sink (5) having a first clearance side (6a, 6b) centered relative to a longitudinal axis (L) of the heat sink (5), and sever...

Zusammenfassung:	A cooling fan (1) for cooling an electronic device (2) is disclosed. The cooling fan (1) comprises a heat sink (5) thermally connectable to the electronic device (2), the heat sink (5) having a first clearance side (6a, 6b) centered relative to a longitudinal axis (L) of the heat sink (5), and several thermally conductive fan blades (13) arranged in a circle centered on the longitudinal axis (L). The fan blades (13) are rotatable relative to the heat sink (5) about the longitudinal axis (L) by a motor (19) and each fan blade (13) has a second clearance side (14) facing the first clearance side (6a, 6b). A clearance space (18) is provided between the first clearance side (6) and each second clearance side (14), the majority of said clearance spaces (18) having a size of 100 micrometer or less in a direction perpendicular to the first clearance side (6a, 6b) and the corresponding second clearance side (18).
