Publication number: 20240138104Abstract: A cold plate assembly includes a thermally conductive cold plate having a first surface attachable to a heat generating electronic component of an information processing system. An opposite second surface includes an array of hollow riser columns extending orthogonally and filled with a saturated working fluid for heat transfer. The cold plate assembly includes a stacked arrangement of fins physically attached perpendicularly to at least one of the riser columns. The vertical levels of fins are spaced apart, substantially in parallel with each other and the second surface to form a fin stack. An encapsulating lid of the cold plate assembly is attached to the second surface to form a liquid cooling cavity that encloses the fin stack. The encapsulating lid includes an intake port and an exhaust port that are laterally positioned and aligned with the fin stack to create liquid flow through the fin stack for liquid cooling.Type: ApplicationFiled: October 23, 2023Publication date: April 25, 2024Inventor: AUSTIN SHELNUTT

Publication number: 20240138118Abstract: A rack liquid cooling manifold (RLCM) system includes a supply manifold to receive a cooling liquid for cooling heat-generating electronic components via a cold plate and a return manifold to exhaust the cooling liquid from the cold plate. The RLCM system includes a manifold control unit (MCU) integrated into the supply manifold or the return manifold that is communicatively coupled to a supply control valve and a datacenter control system. The MCU includes a memory with rack temperature and liquid control (RTLC) code and a processor that processes the RTLC code to cause the MCU to: receive node-level liquid telemetry data originating from one or more liquid telemetry sensors integrated at a respective node; trigger actuation of the supply control valve to control a rate of cooling liquid flow into the supply manifold, partly based on the liquid telemetry data; and communicate rack level information with the datacenter control system.Type: ApplicationFiled: October 23, 2023Publication date: April 25, 2024Inventor: AUSTIN SHELNUTT

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: 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
