Patent number: 8125779Abstract: A front-to-back cooling system allows cooling of an apparatus containing two orthogonal sets of modules. Each set of modules is independently cooled. A vertical set of modules is cooled with vertical air flow across the modules that enters from a front of the apparatus and exhausts from a back of the apparatus. A horizontal set of modules is cooled with horizontal front-to-back air flow. When the horizontal set of modules is at the front of the apparatus, a plenum extending exterior to the vertical set of modules allows exhausting horizontally flowing air to the rear of the apparatus. When the horizontal set of modules is at the rear of the apparatus, a plenum extending exterior to the vertical set of modules allows moving air from the front of the apparatus to a chamber holding the horizontal modules.Type: GrantFiled: September 23, 2010Date of Patent: February 28, 2012Assignee: Juniper Networks, Inc.Inventors: Gunes Aybay, Sindhu Pradeep, Jean-Marc Frailong, David J.

Patent number: 8120913Abstract: An electronic flight bag computer (EFB) includes a housing defining first and second compartments that are fluidly isolated from and in thermal communication with one another. The first compartment contains electronic components connected to a user interface on an exterior portion of the housing for providing interactive flight related computation functions to a user. The second compartment contains a forced convection cooling component in thermal communication with the electronic components. The forced convection cooling component directs a flow of cooling fluid into the second compartment to convey heat produced by the electronic components out of the housing, such that the cooling fluid in the second compartment remains fluidly isolated from the electronic components in the first compartment of the housing.Type: GrantFiled: June 29, 2009Date of Patent: February 21, 2012Assignee: Rosemount Aerospace Inc.Inventor: Curtis Wicks

Patent number: 8102651Abstract: Method and apparatus providing airflow through a chassis including an upstream column of memory modules and a downstream column of memory modules. The airflow is divided into first and second separate airflow streams extending from an upstream end of the upstream column to a downstream end of the downstream column. The first airflow stream is guided into contact with a single memory module operably-installed in the upstream column and to avoid contact with any memory module in the downstream column. The second airflow stream is guided to avoid contact with any memory module in the upstream column and into contact with a single memory module operably-installed in the downstream column. The improved cooling enables the extended use of a single memory module per channel, even though the thermal load on such a memory module is greater.Type: GrantFiled: October 2, 2009Date of Patent: January 24, 2012Assignee: International Business Machines CorporationInventors: Patrick M.

Patent number: 8098489Abstract: The invention broadly contemplates an integrated thermal system that is capable of simultaneously cooling multiple, separate heat generating components of an electronic device. The integrated thermal system according to one embodiment of the invention takes the form of a CPU heat sink designed to intelligently maximize available airflow, utilizing multidirectional airflow cooling of a plurality of heat generating components on the motherboard. The heat sink is designed such that airflow provided by a single fan is captured and directed to nearby/adjacent components, thus cooling these components. The invention thus provides an integrated cooling solution and removes the need for multiple cooling systems/solutions.Type: GrantFiled: March 27, 2009Date of Patent: January 17, 2012Assignee: Lenovo (Singapore) Pte.
