Patent number: 7362571Abstract: Flow conditioners for use with air inlets on computer cabinets are disclosed herein. In one embodiment, a large computer system includes a plurality of computer cabinets arranged in close proximity to each other. Each of the computer cabinets can include a fan, impellor, or other air mover positioned proximate to an inlet that receives cooling air from a plenum, such as a floor plenum. In this embodiment, a flow conditioner configured in accordance with the present invention can be positioned proximate to the air inlet. The flow conditioner can include a vortex diffuser and a flow-speed normalizer. The flow-speed normalizer can include a perforated screen that forms a cylinder around the inlet, and the vortex diffuser can include one or more vanes that extend across the cylinder adjacent to the inlet.Type: GrantFiled: September 15, 2005Date of Patent: April 22, 2008Assignee: Cray Inc.Inventors: Douglas P. Kelley, Alexander I. Yatskov

Patent number: 7359193Abstract: Electronic equipment includes a chassis that compose a case, a first printed circuit board, an MPU and a memory both of which are mounted in the case and consume high power, and a cooling fan for taking in air from the outside into the inside of the case. The cooling fan supplies an air current to the MPU and the memory to cool them. The electronic equipment also includes a wind direction control board between the cooling fan and the MPU and the memory to partition the inside of the case into at least two subspaces. The wind direction control board has an opening at a position opposed to the MPU and the memory.Type: GrantFiled: October 5, 2005Date of Patent: April 15, 2008Assignee: NEC CorporationInventor: Masaru Deguchi

Patent number: 7359205Abstract: Embodiments of the present invention recite an electronic device comprising a chassis, a backplane, at least one heat generating component coupled with the backplane, and a fan. In embodiments of the present invention, the chassis comprises at least one air inlet disposed on a side of the chassis and at least one exhaust outlet disposed on the bottom surface of the chassis. The heat generating component is suspended from said backplane when coupled therewith and is disposed above the at least one exhaust outlet. The fan draws cooling air through the at least one air inlet and expels the cooling air through the at least one exhaust outlet.Type: GrantFiled: November 9, 2005Date of Patent: April 15, 2008Assignee: NVIDIA CorporationInventors: Xiaohua H. Sun, Don Le

Patent number: 7352576Abstract: A multi-processor system has a tubelike computer module including plural mother boards configured onto plural side walls of a rack body to form a unitary, continuous and non-segment airflow channel. The airflow channel of the tubelike computer module has larger space and fewer barriers to allow the airflow passing through smoothly, and to reduce wind noises or turbulences. Therefore, the system achieves optimum heat-dissipation efficiency and noise reduction by means of specific space arrangement and less cooling system requirement.Type: GrantFiled: July 10, 2006Date of Patent: April 1, 2008Assignee: Tyan Computer CorporationInventor: John McClure

Patent number: 7352573Abstract: A power supply unit (PSU) has walls which define an internal volume of the PSU. A metal sheet forming left and right side walls and an upper wall is provided with plural perforations on each of those walls. The perforations are circular in shape, and formed in a regular grid pattern. The perforations are formed by punching the metal sheet before it is bent into shape. The perforations in the housing of the PSU allow hotspots to be carried through the walls of the housing of the PSU, following which the hotspots are unable to damage internal components of the PSU. This allows the use of reduced flow rate fans.Type: GrantFiled: October 6, 2005Date of Patent: April 1, 2008Assignee: High Performance Enterprise Public Limited CompanyInventor: William Wong
