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)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Cooling fan","description":"A cooling fan (1) for cooling an electronic device (2) is disclosed.
