Cooling fan, for electronic components, has a frame with spaced tongues angled outwards giving increased air inflow gaps for the fan wheel to give a stronger cooling effect

摘要

The cooling fan, for electronic components, has a frame (21) with spaced tongues (213) around it, with air inflow gaps (214) formed by the spaces (215) between them. The tongues are angled outwards, and have a semicircular or rectangular shape. The frame has a center hub seat (212) and connecting rods (211), to accommodate the hub (221) of the fan wheel (22) with its blades (222).
