Patent number: 10375853Abstract: In an exemplary electronic device with a cooling fan, a fan assembly is attached to a keyboard assembly of the electronic device. The fan assembly includes an impeller at least partially inside a fan enclosure. The fan enclosure has, on a surface, an inlet opening and an external protrusion. The electronic device further includes a bottom case. The fan assembly is positioned between the keyboard assembly and the bottom case and oriented such that the inlet opening and the external protrusion face the bottom case. The external protrusion maintains a passage between the fan enclosure and the bottom case that allows air to enter the inlet opening and also resists interference between the rotating impeller and the stationary bottom case.Type: GrantFiled: August 21, 2017Date of Patent: August 6, 2019Assignee: Apple Inc.Inventors: Anthony J. Aiello, Jonathan L. Berk, Karen Cheng, Jesse T. Dybenko, Trevor Edmonds, Kwonil D. Fleischman, Richard A. Herms, Eric A. Knopf, Arash Naghib Lahouti, Brad L. Patton

Publication number: 20180352676Abstract: 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.Type: ApplicationFiled: May 31, 2018Publication date: December 6, 2018Inventors: Brett W. DEGNER, Eric R.

Patent number: 9913400Abstract: The present application describes various embodiments regarding systems and methods for providing efficient heat rejection for a lightweight and durable compact computing system having a small form factor. The compact computing system can take the form of a desktop computer. The desktop computer can include a monolithic top case having an integrated support system formed therein, the integrated support system providing structural support that distributes applied loads through the top case preventing warping and bowing. A mixed flow fan is utilized to efficiently pull cooling air through the compact computing system.Type: GrantFiled: May 26, 2015Date of Patent: March 6, 2018Assignee: Apple Inc.Inventors: Brett W.

Publication number: 20180003183Abstract: 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.Type: ApplicationFiled: September 19, 2017Publication date: January 4, 2018Applicant: APPLE INC.Inventors: Jesse T.

Patent number: 9853580Abstract: A method to reduce acoustic noise in a cooling fan motor is disclosed. The method includes reducing the slew rate of a PWM (pulse width modulation) voltage waveform applied to energize a coil of the fan motor. This slew rate reduction results in lower mechanical vibrations and acoustic noise in the fan motor. In one embodiment, the slew rate reduction is performed during startup of the fan motor, when the motor is spinning slowly and there is little air flow noise. In another embodiment, the slew rate reduction is not performed during high speed operation of the fan motor, when the fan motor is spinning very fast and air flow noise masks the motor noise. In one embodiment, there is variable slew rate control depending on the speed of the fan motor.Type: GrantFiled: March 11, 2014Date of Patent: December 26, 2017Assignee: Apple Inc.Inventors: Brad Lee Patton, Anthony Joseph Aiello, Jesse T.

Publication number: 20170067470Abstract: Electronic devices have peripheral drive centrifugal fans having smaller hubs and increased air flows to manage heat levels within the electronic device. A peripheral drive centrifugal fan includes a fan housing, an impeller including a plurality of blades, and a plurality of stacked inductor groups radially disposed about the impeller. Some of the blades have magnetically active portions. Each stacked inductor group includes first and second coils configured to impart a variable magnetic force to the magnetically active portion of a blade to drive the impeller along a rotational direction. The first and second coils can be selectively energizable independently from each other to provide greater control of the impeller.Type: ApplicationFiled: June 15, 2016Publication date: March 9, 2017Inventors: Brad L. PATTON, Anthony J. AIELLO, Jesse T. DYBENKO

Publication number: 20170002836Abstract: A fan includes an impeller having blades of varying chord lengths. The fan includes a fan housing surrounding the impeller. The fan housing includes a protruding region, or throat, separated from each passing blade by a clearance, or throat gap, that varies according to the chord length. During rotation of the impeller, the impeller blades rotate about a rotational axis, passing the protruding region defining a minimum radial gap to the protruding region. Due to their different chord lengths, the impeller blades pass the throat region at different throat gaps. Shorter blades are likely to have lower amplitude static pressures and lower air velocities resulting at the blade tip, and are hence likely to generate a lower amplitude acoustic pulse at the protruding region. The variety of chord lengths modulate the amplitude of the pressure to spread acoustic sound across multiple frequencies thereby reducing peak amplitude of the acoustic sound.Type: ApplicationFiled: July 1, 2016Publication date: January 5, 2017Inventors: Philippe P. HERROU, Richard A. HERMS, Jesse T. DYBENKO

Patent number: 9341192Abstract: 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.Type: GrantFiled: October 23, 2013Date of Patent: May 17, 2016Assignee: Apple Inc.Inventors: Anthony Joseph Aiello, Jesse T.

Patent number: 9334867Abstract: The described embodiments relate generally to improving performance characteristics of a low profile fan. More specifically configurations having sloped fan blade edges are disclosed. By applying a gradual slope to each of the fan blades, performance of the fan can be increased without risking contact or rubbing between the fan blades and a fan housing. In some embodiments, the sloped fan blades can be configured to prevent contact when bearings of the fan include a certain amount of tilt play.Type: GrantFiled: May 3, 2013Date of Patent: May 10, 2016Assignee: Apple Inc.Inventors: Anthony Joseph Aiello, Jesse T.
