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.

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: Fan assemblies are disclosed. Fan assemblies include an impeller with asymmetric design. For example, an impeller may include a first set of blades with one geometry and second set of fan blades with another geometry. This enables a dual-inlet centrifugal fan to generate different air flow performance characteristics for the air entering one fan inlet compared to the air entering the other fan inlet. The impeller, with different fan blade configurations, can better handle air flow entering the fan assembly through different inlets, particularly when the air flow conditions differ through the inlets due to impeding structures (e.g., motor, struts, etc.). As a result, air flow distribution from air leaving the impeller, including the locations associated with the different fan blade configurations, is relatively uniform. Beneficially, when air flow distribution uniformity increases, the fan assembly operates more efficiently, as air flow pressure losses due to flow separation are mitigated.

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.
