Patent number: 11333170Abstract: 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.Type: GrantFiled: October 7, 2019Date of Patent: May 17, 2022Assignee: Apple Inc.Inventors: Anthony Joseph Aiello, Jesse T.

Patent number: 11215193Abstract: An electronic device with a fan assembly is disclosed. The fan assembly includes an impeller and an insert separated from the impeller by a gap. The fan assembly increases airflow by rotationally driving the impeller. For a sufficient rotational speed of the impeller, the airflow reaches a level that provides a force that displaces the insert. The displacement may include movement and/or compression of the insert. As a result of the displacement, the gap between the impeller and the insert increases. The increased gap reduces the pressure and associated noise that is otherwise caused by the airflow. When the rotational speed of the impeller reduces or ceases, the insert returns to its initial position. In this manner, the fan assembly includes a self-adjusting gap that changes based on the airflow.Type: GrantFiled: February 14, 2020Date of Patent: January 4, 2022Assignee: Apple Inc.Inventors: Halil Berberoglu, Cheng Ping Tan, Arash Naghib Lahouti, Richard A.

Patent number: 10422350Abstract: 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: GrantFiled: July 1, 2016Date of Patent: September 24, 2019Assignee: Apple Inc.Inventors: Philippe P.

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

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.

Patent number: 7301773Abstract: A heat collection apparatus is mounted to the heat source using a gimbal plate, which includes a gimbal joint. The gimbal joint enables application of a retaining force to the heat collection apparatus as a single-point load. The retaining force is applied along a vector that is collinear to the face-centered normal vector of the thermal interface of the heat source. This results in a balanced and centered application of the retaining force over the thermal interface area. The gimbal plate is mounted directly to a circuit board using spring means. The spring means regulate the amount of mating force directed through the gimbal joint to the heat collection device. Because the gimbal joint is rotation-compliant, the two mating faces making up the thermal interface are forced into a parallel mate. In this manner, a high performance TIM interface is generated.Type: GrantFiled: September 20, 2004Date of Patent: November 27, 2007Assignee: Cooligy Inc.Inventors: Richard Grant Brewer, Paul Tsao, Richard Herms, Mark Munch, Mark McMaster, Dave Corbin

Patent number: 5835004Abstract: Improved tape assemblies for delivering electrical devices to work stations at which the devices are installed. Each of the devices comprises a laminar electrical component sandwiched between two laminar metal members, and is preferably a PTC circuit protection device. In the assemblies, the electrical components are discrete components, but they are contacted by, and linked together through, laminar metal members which, after the assembly has been divided into separate devices, provide leads which contact and extend away from the electrical component. Preferably the metal members are prepared by cutting and forming a single strip of metal. Preferably the assembly is free from any longitudinally continuous carrier strip which much be discarded after the devices have been separated from each other. Preferably, the assemblies are sufficiently flexible to be wrapped around a reel and unwrapped at the work station.Type: GrantFiled: April 21, 1995Date of Patent: November 10, 1998Assignee: Raychem CorporationInventors: James P.
