Abstract: The described embodiments relate to improving efficiency of a low-profile cooling fan. In one embodiment, an impeller of the cooling fan includes a shroud which covers a central portion of the impeller, thereby allowing a central inlet portion of the blades to have an increased fan blade height when compared to a cooling fan constrained by minimum part tolerances between the fan blades and a portion of the fan housing. In some embodiments, the impeller includes splitter blades that can improve performance of the low-profile cooling fan.

Abstract: A thermal management system that includes a fan assembly, a heat exchanger, and an insulating box is described. The fan assembly can have two impellers and a housing that includes two scroll portions. An internal portion of the scroll wall can be truncated. A motor housing can be connected to the fan housing via multiple struts. The struts can be oriented angularly with a tangential component and can slope inward to increase the effective inlet area. The heat exchanger can be formed of a fin stack that has a curved body that defines an airflow path that turns radially from the inlet to the exhaust. The heat exchanger can have an inlet that is smaller than the exhaust. The heat exchanger can be connected to one or more heat pipes. The insulating box can have a grid that directs air to certain specific directions.

Abstract: A cooling system for optimizing fan air flow performance without compromising acoustic performance is disclosed. At least three fan feature embodiments are disclosed: (1) sloped fan blades, (2) sloped impeller hubs, and (3) inlet flow guidance features. For the first embodiment, fan blades attached to an impeller disc and having leading edges that progressively curve toward a center of the impeller disc. For the second embodiment, the impeller disc is attached to and centered on an impeller hub that has a sloped hub surface that progressively curves toward the fan blades. For the third embodiment, an inlet flow guidance feature is positioned within a region surrounding a fan's inlet promoting smooth passage of air into the fan. In some embodiments, all three fan features are combined.

Abstract: The described embodiments relate generally to cooling fans and more specifically to a method for balancing an impeller assembly included in a cooling fan. In one embodiment, a balancing ring with an asymmetric shape can be included in an impeller assembly and rotated to correct an unbalance in the impeller assembly. In another embodiment, a balancing ring assembly can be provided including an inner balancing ring and an outer balancing ring. The size and shape of the inner balancing ring can be modified to better correct any unbalance in the impeller assembly.

Abstract: A fan assembly having a reduced dimension formed by several modifications is described. The fan assembly includes a stator having stator coils positioned within a recessed portion of a pillow that receives the motor. The stator may include wire connections positioned between adjacent stator coils and designed to terminate wires of the stator coils. The wire terminations may be on a protrusion or a post positioned between adjacent stator coils, or alternatively, the wire terminations may be disposed on protruding features of a bushing. The protrusion may be formed from an electrically conductive material and electrically connected to a motor control circuit via a flexible printed circuit. In some embodiments, the protrusion is part of an electrically neutral stator bushing having several pins. Also, a gap region between the bushing and a flange feature is designed to improve an adhesive joint.

Abstract: An electronic device includes a fan assembly that draws air (including heated air) away from components and forces the air out of the electronic device. The fan assembly includes a guide vane located in the fan housing. Subsequent to air entering the fan assembly via the fan inlets, the guide vane is designed to direct the air to a fan outlet. Further, the guide vane is designed and positioned in the fan assembly to limit or prevent flow separation that may cause the heated air to recirculate and may also cause increased turbulence leading to elevated acoustic noise. Furthermore, the guide vane may include a tapered region to allow the heated air to readily flow over the guide vane to limit or prevent a vortex from occurring within the fan assembly. Using the guide vane, the fan assembly drives more air at the same fan speed and lowers noise generation.
