Publication number: 20160198600Abstract: Modular elements employing latches secured by linkages are disclosed. A modular element may include a chassis body in communication with a latch, control body, and control arm of the modular element. The modular element is removable from or secured to an enclosure using the latch. The latch may remain secured to the enclosure in a locked mode by being rotated to engage a control catch of a control arm of a linkage. By connecting the control arm to the control body with a rigid member connected to the control body with first and second rotary joints, the rigid member transforms a control body movement into a rotary motion of the control arm to disengage the control arm from the latch. In this manner, the modular element may be disengaged from the enclosure to facilitate upgrades or maintenance of electronic components supported by the chassis body.Type: ApplicationFiled: January 21, 2015Publication date: July 7, 2016Inventors: Matthew A. BUTTERBAUGH, Eric A. ECKBERG, Camillo SASSANO, Kevin L. SCHULTZ, Scott A. SHURSON

Publication number: 20160192529Abstract: Modular elements employing latches with flexure bearings are disclosed. A modular element may include a chassis body supporting electronic components. The body is in communication with a latch and a control member of the modular element. The modular element is removable from or secured to an enclosure using the latch. The latch may engage the enclosure and may remain engaged by being secured by interfacing with a catch of an arm of the control member. By connecting the arm to the control body with a flexure bearing, the flexure bearing may urge the catch into a detent of the latch to secure the latch and keep the modular element secured to the enclosure. The latch may be disengaged from the control member by removing the catch from the detent. In this manner, the modular element is efficiently secured and removed from the enclosure.Type: ApplicationFiled: December 29, 2014Publication date: June 30, 2016Inventors: Matthew A.

Publication number: 20160183396Abstract: Modular elements removable from enclosures and employing cams forming detent features with latches are disclosed. A modular element may include a chassis body supporting electronic components. The modular element is removable from or secured to an enclosure using a latch. The latch may engage the enclosure and may remain engaged with the enclosure by being secured by interfacing with a cam. By forming the cam with a predetermined shape, a detent feature may be established with the latch to secure the latch and maintain the modular element locked to the enclosure. The latch may be disengaged from the cam by applying a disengagement motion to the cam and allow the latch to move relative to the chassis body and disengage from the enclosure. In this manner, the modular element is efficiently secured and removed from the enclosure with minimum obstruction to airflow to the electronic components.Type: ApplicationFiled: December 30, 2014Publication date: June 23, 2016Inventors: Matthew A.

Patent number: 9354001Abstract: A heat exchanger core optimization method is provided for a heat exchanger door which resides at an air inlet or outlet side of an electronics rack, and includes an air-to-coolant heat exchanger with a heat exchanger core. The core includes a first coolant channel coupled to a coolant inlet manifold downstream from a second coolant channel, and the first channel has a shorter channel length than the second channel. Further, coolant channels of the core are coupled to provide counter-flow cooling of an airflow passing across the core. The core optimization method determines at least one combination of parameters that optimize for a particular application at least two performance metrics of the heat exchanger. This method includes obtaining performance metrics for boundary condition(s) of possible heat exchanger configurations with different variable parameters to determine a combination of parameters that optimize the performance metrics for the heat exchanger.Type: GrantFiled: February 25, 2013Date of Patent: May 31, 2016Assignee: LENOVO ENTERPRISE SOLUTIONS (SINGAPORE) PTE.
