Patent number: 7729115Abstract: An electrical apparatus having a cooling system includes a first cover to cover a first part of the electrical apparatus to be cooled and a second cover substantially enclosing the first cover to define a surrounding space. A base plate on which the first cover is mounted defines an environmentally-sealed enclosure that houses the first part of electrical apparatus. A first circulation device causes air to circulate in the environmentally-sealed enclosure and a second circulation device causes a cooling fluid to circulate around the surrounding space. A heat transfer structure is positioned on each side of the first cover. A third cover is mounted to an opposite side of the base plate from the first cover to define a second enclosure that houses a second part of the electrical apparatus to be cooled. A heat exchange structure is positioned within the second enclosure.

Patent number: 7724515Abstract: In a disk array apparatus, by taking note of a first sound of a specific frequency which is a noise element of original sounds generated from a fan, a second sound whose phase is inverted to that of the first sound is generated by a structure of a cooling air flow path passing through the fan, and the second sound is synthesized with the first sound on the cooling air flow path, thereby reducing the noise. For example, an exhaust duct is located on a fan unit in an upper part of the apparatus, two flow paths extending to an exhaust port are formed in an internal structure of the exhaust duct, and the two flow paths are designed so that the difference in the flow path length therebetween becomes equivalent to half wavelength of the specific frequency.Type: GrantFiled: January 23, 2008Date of Patent: May 25, 2010Assignee: Hitachi, Ltd.Inventors: Hiroshi Fukuda, Hitoshi Matsushima

Patent number: 7643284Abstract: The present invention provides a portable computer in which an increase in temperature of a housing is suppressed. In the present invention, a guide plate is provided to suppress an increase in temperature of a bottom surface. When a cooling fan device operates, outside air taken in from inlet openings flows as an air current through a narrow flow path formed between the guide plate and the bottom surface. A flow velocity of the air current can be increased by narrowing the flow path, and heat exchange with the guide plate can be effectively performed, thereby sufficiently cooling a cooling surface. The cooled guide plate cools an air layer between the guide plate and the heat sink and thermally insulates between the air layer and the bottom surface.Type: GrantFiled: October 29, 2007Date of Patent: January 5, 2010Assignee: Lenovo Singapore Pte.

Patent number: 7630201Abstract: While one of ventilation fans operates, the other ventilation fan is at rest. Air flows from the operating ventilation fan to the ventilation fan at rest. The airflow passes through an air passage defined in a heat radiating member located between the ventilation fans. Dust cumulates at the entrance of the air passage. The other ventilation fan is then driven to operate while the operating ventilation fan is brought to rest. Airflow is generated in the reverse direction. The airflow is inverted within the air passage. The inverted airflow serves to remove the dust from the entrance of the air passage. The cumulation of the dust can thus reliably be avoided. Accordingly, no dust filter is required in the path of airflow outside the air passage. Airflow of a sufficient amount can always be maintained in the air passage.Type: GrantFiled: March 6, 2006Date of Patent: December 8, 2009Assignee: Fujitsu LimitedInventor: Kazutoshi Asahi

Patent number: 7529087Abstract: A chassis panel for a computerized device includes ventilation elements that visually obscure electronic components disposed within an associated chassis and that minimize airflow resistance. Each ventilation element includes a first angled ventilation portion having openings that provides limited visual access to the electronic components disposed within the chassis. Each ventilation element also includes a second angled ventilation portion having openings that provide no visual access to the electronic components disposed within the chassis. As such, the ventilation elements visually obscure the electronic components disposed within the chassis without the need for additional materials such as screens, mesh, or foam. Also, the openings of the first and second ventilation portions provide the chassis panel with a relatively large free area ratio, such as between about 42% and 48% or greater depending on hole pitch values and opening sizes.Type: GrantFiled: February 24, 2006Date of Patent: May 5, 2009Assignee: Cisco Technology, Inc.Inventors: Craig Donald Dubrule, Phong Hoang Ho
