Patent number: 7623346Abstract: Airflow is introduced into an enclosure through an air inlet in an electronic component unit. The airflow runs toward a first electronic component. The airflow absorbs heat from the first electronic component. The first electronic component is thus sufficiently cooled. A second electronic component is mounted on a printed wiring board at a position remoter from the air inlet than the position of the first electronic component. An air intake opening is formed in the enclosure. The air intake opening is defined at a section of the enclosure opposed to the printed wiring board at least between the first and second electronic components. Airflow is introduced toward the second electronic component through the air intake opening. The second electronic opening is thus sufficiently cooled. In this manner, the first and second electronic components are cooled equally to the utmost.Type: GrantFiled: May 21, 2008Date of Patent: November 24, 2009Assignee: Fujitsu LimitedInventors: Hiromitsu Fujiya, Hideki Kimura

Publication number: 20090262497Abstract: Method and apparatus for substantially preventing recirculation of heated air from an exhaust outlet of an expansion card to an air inlet of the expansion card, wherein the air inlet and exhaust outlet are both on the same end of the chassis. The apparatus comprises a chassis with a chassis fan, a motherboard within the chassis having an expansion card connector, and an expansion card in communication with the expansion card connector and secured to the front end of the chassis. The expansion card also includes a card fan configured to move cooling air through the air inlet to the exhaust outlet. An air duct redirects the hot air from the exhaust outlet to prevent recirculation into the expansion card and causes the heated air to exit through the chassis fan. The air duct may include a longitudinal segment through a computer module and a lateral segment selectively securable over the exhaust outlet.Type: ApplicationFiled: April 22, 2008Publication date: October 22, 2009Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: William Norris Beauchamp, Karl Klaus Dittus, Whitcomb Randolph Scott, III, Jean Jidong Xu

Publication number: 20090257188Abstract: A docking plenum for a rack is disclosed. The docking plenum includes a pair of sides that are coupled to first and second panels at the top of the docking plenum. The panels at the top of the docking plenum are separated from one another by an aperture. The docking plenum includes a front opening and a rear opening between the two sides. Each of the front opening and the rear opening are sized to receive a rack. The placement of a first rack in the front opening and a second rack in the rear opening creates a heated air cavity that is formed by the racks, the floor of the docking plenum, and the panels at the top of the docking plenum. When the racks are placed in the opening, and when one or more fans in the computer systems are activated, the fans draw air from outside the plenum across the interior of the computer systems. Heated air exits the computer systems and enters the heated air cavity. The heated air exits the heated air cavity through the aperture in the top of the docking plenum.Type: ApplicationFiled: April 11, 2008Publication date: October 15, 2009Inventors: R. Steven Mills, Ty R. Schmitt

Publication number: 20090244827Abstract: An information handling system's thermal management is selectively altered by coupling a thermal barrier to the bottom surface of the information handling system chassis so that an air channel insulates against the passage of thermal energy from the bottom surface. A vent opening in a side of the thermal barrier allows airflow through the air channel to a vent opening of the information handling system. The airflow through the air channel cools the base of the thermal barrier so that an end user will experience reduced thermal energy if the information handling system rests on the end user, such as in the end user's lap.Type: ApplicationFiled: March 29, 2008Publication date: October 1, 2009Inventors: Mark Rehmann, David Lawrence McKinney, Anil Damani
