Patent number: 11092986Abstract: Performance of a system may be boosted with a boost dock that seals fan interfaces to improve airflow through an information handling system. An apparatus may include a first port configured to seal a first interface between the apparatus and an information handling system. The apparatus may also include a first blower configured to receive ambient air as cool intake air and to blow the cool intake air into the information handling system through the first interface sealed by the first port. The apparatus may further include a second blower configured to receive warm exhaust air from the information handling system through the first interface sealed by the first port and to blow the warm exhaust air out of the apparatus. A method may include steps of sealing a first interface, receiving ambient air, blowing cool intake air, receiving warm exhaust air, and blowing warm exhaust air.Type: GrantFiled: June 30, 2017Date of Patent: August 17, 2021Assignee: Dell Products L.P.Inventors: Travis North, Austin Shelnutt, Philip Grossmann, Chris Helberg

Patent number: 10426063Abstract: A method for cooling components of an information handling system (IHS) includes detecting, via a thermal control system, at least one pressure reading, at least one temperature reading and at least one current cooling device setting of the IHS. At least one new cooling device setting is calculated based on the pressure reading and the temperature reading. The new cooling device setting is compared to the current cooling device setting associated with one or more cooling devices of the IHS. In response to the new cooling device setting being different from the current cooling device setting, one or more of the corresponding cooling devices are triggered to adjust its/their current cooling device setting to the new cooling device setting corresponding to the respective cooling device.Type: GrantFiled: February 3, 2015Date of Patent: September 24, 2019Assignee: Dell Products, L.P.Inventors: Travis C. North, Austin Michael Shelnutt, Chris Helberg

Patent number: 10399190Abstract: An assembly for cooling a heat dissipating device reducing the thermal contact/interface resistance between a heatsink and a heat dissipating device includes: a heat dissipating device having a heat releasing surface; a heatsink having a heat absorbing surface; a gasket extending between the heat releasing surface and the heat absorbing surface to provide a sealed interstitial cavity; and a working fluid provided within the cavity. The working fluid has specific thermal properties that cause the fluid to (i) absorb latent heat and evaporate from a liquid to a vapor at the liquid surface in contact with the heat releasing surface during operation of the heat dissipating device and (ii) condense from the vapor back to the liquid when the vapor contacts the heat absorbing surface of the heatsink, thus releasing the latent heat from the vapor to the heatsink.Type: GrantFiled: August 8, 2014Date of Patent: September 3, 2019Assignee: Dell Products, L.P.Inventors: Travis C. North, Austin Michael Shelnutt, Chris Helberg, Rene Jason Salas

Patent number: 10283999Abstract: An information handling system (IHS) includes a base station that has a transmitter coil to generate a magnetic field for charging a portable power source of a battery-powered electronic device. A receiver coil magnetically receives power from the transmitter coil of the base station. A power control module connected to the portable power source and the receiver coil charges the portable power source with the received power. A flexible ferrite shield is positioned on a side of the receiver coil opposite to the transmitter coil to shield the IHS electronics. A pneumatic diaphragm is formed by a portion of the flexible ferrite shield that is positioned for oscillating movement into a center cavity of the receiver coil. A diaphragm actuator is attached to the pneumatic diagram and is responsive to a triggering signal to oscillate the pneumatic diaphragm to disperse thermal energy that is generated by the receiver coil.Type: GrantFiled: July 19, 2016Date of Patent: May 7, 2019Assignee: Dell Products, L.P.Inventors: Chris Helberg, Travis C. North, Andrew Sultenfuss, Austin M. Shelnutt

Patent number: 10274977Abstract: Control signals, such as PWM control signals, can be used to control aspects of a cooling system and can be generated using proportional-integral-derivative (PID) control. PID control systems for cooling systems are designed based on default environmental and system characteristics and pre-programmed for operation prior to delivery to customers or end users. Changes in environmental and system characteristics, such as component aging, environmental variations, and variation in manufacturing from system to system, such as heat sink effectiveness and application of thermal pastes, can impact system level performance of the control system. Adjusting gain parameters for the P, I, and D components of a PID control signal can reduce negative impact on system performance resulting from such changes and allow the control system to better adjust to external factors.Type: GrantFiled: March 22, 2017Date of Patent: April 30, 2019Assignee: Dell Products L.P.Inventors: Travis North, Chris Helberg, Austin Shelnutt, Kevin Locke, Joohyun Woo
