    摘要: A method and apparatus to improve air flow in an air circulating fan assembly by forming an inlet opening in a fan assembly. A static air pressure profile is calculated along a top portion of the fan assembly configured to operate in an enclosure. The shape of a section of the inlet opening in the top portion of the fan assembly is changed based on a pressure contour of the calculated static air pressure profile. The method is repeated iteratively one or more times using an inlet opening changed by a previously calculated static air pressure profile when calculating a subsequent static air pressure profile. The inlet opening is positioned in the top surface of the fan assembly so that the centroid of the inlet opening is laterally offset with respect to the rotational axis of an impeller in the fan assembly.

    摘要: A fan assembly for a computing device is disclosed. The device can include an impeller having a number of blades and a motor for turning the blades. The motor can turn the blades via a magnetic interaction between the impeller and the motor. A thrust bearing can be used to control a position of the impeller relative to the motor. In particular, the impeller can be configured to rotate around an axis and the thrust bearing can be used to control movement of the impeller in a direction aligned with the axis. In one embodiment, the impeller can be configured to generate aerodynamic forces, such as lift, and the parameters associated with the thrust bearing can be selected to counteract the aerodynamic forces so that the impeller remains within a desired positional range relative to the motor.

    摘要: A centrifugal blower in a cooling system of an electronic device having asymmetrical blade spacing with acceptable balance. The asymmetrical blade spacing is determined according to a set of desired acoustic artifacts that are favorable and balance that is similar to that found with equal fan blade spacing. In one embodiment, the fan impeller can include sixty one fan blades.

    摘要: A method of optimizing placement of a control source relative to a noise source includes establishing a first pool of constructive chromosomes, each constructive chromosome defining a potential spatial position for the control source in an acoustic space and each constructive chromosome including a plurality of constructive genes having a value-based value that represents an ordinate related to the potential spatial position. A second pool of constructive chromosomes is established by manipulating the value-based values of constructive genes from at least a portion of the plurality of constructive chromosomes of the first pool to create a plurality of modified constructive chromosomes, and evaluating a fitness characteristic of at least some of the constructive chromosomes from the first pool and/or at least some of the constructive chromosomes from the second pool. A portion of the constructive chromosomes are eliminated from the first and/or second pools based on the fitness characteristic.
