Fan (4)

Abstract

[Purpose of the Item]: This design relates to a cooling fan assembly, particularly a series-connected fan assembly, used in electronic devices to drive airflow for cooling heat-generating components. [Design Description]: This design consists of a pre-stage fan and a post-stage fan assembly. As shown in the figures, each fan's overall appearance extends outward from the periphery of a fan hub with a plurality of blades. The blades of both the pre-stage and post-stage fans have their ends facing the outer top surface of the hub, exhibiting the shape shown by the solid lines in the views. Furthermore, as shown in the front and rear views, the blades of the pre-stage and post-stage fans exhibit different overlapping patterns. Overall, this design highlights its ingenious and cleverly designed collaborative form, presenting an innovative aesthetic with an industrial style. It provides a novel visual experience and truly meets the requirements for an innovative design patent. The dotted lines in the views represent parts that are not claimed in this design.
