    摘要: A fan vibration absorbing structure includes a bearing cup and a vibration absorbing element. The bearing cup includes a first section, a second section and a bearing holding hole. The first and the second section are connected end-to-end to enclose a receiving space therein, which communicates with the bearing holding hole. The vibration absorbing element is fitted between the first and the second section. With the fan vibration absorbing structure included in a fan, it is able to largely reduce the vibration occurred during fan operation.

    摘要: A blower fan includes a lower plate portion made of a material having a thermal conductivity of 1.0 W/(m·K) or more, and a side wall portion made of a material having a thermal conductivity of 1.0 W/(m·K) or more. An upper plate portion arranged to cover an upper side of the impeller includes an air inlet. The upper plate portion, the side wall portion, and the lower plate portion are arranged to together define an air outlet on the lateral side of the impeller. The blower fan further includes a heat source contact portion with which a heat source is to be in contact, the heat source contact portion being arranged in a surface of the blower fan which faces away from the impeller. The heat source contact portion and the tongue portion are arranged to at least partially overlap with each other in the plan view.

    摘要: A fan assembly for a computing device is disclosed. The fan assembly 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 fluid dynamic 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 rotational axis. In one embodiment, the thrust bearing can be configured to stabilize the impeller when vibratory forces act upon the fan assembly. More particularly, parameters associated with the thrust bearing can be selected to counteract vibratory forces emitted by a speaker system.

    摘要: A bearing cooling structure includes a metal base seat and a plastic bearing cup. The metal base seat has a raised section and an extension section. The plastic bearing cup encloses the raised section and has an inner circumference defining a bearing hole. The extension section horizontally extends from the raised section toward a center of the plastic bearing cup. The extension section has a free end and an upper surface positioned in the bearing hole. A bearing is received in the bearing hole and disposed on the extension section. A bottom face of the bearing is in contact with the upper surface of the extension section. Accordingly, the heat of the bearing can be transferred (conducted) through the extension section to the metal base seat to be dissipated. A fan with the bearing cooling structure is also disclosed.
