Patent number: 7515422Abstract: The present invention provides an electric power converter in which a tip portion of a cooling fin on an air flow inlet side is limited to flow a large quantity of air around a connection portion, where the fin efficiency is high, of a base surface of the cooling fin and the fin so that the cooling efficiency of the cooling fin can be improved. By providing the limiting member, air or atmosphere flowing into the cooling fin is directed to flow toward the fin near the base surface. Further, by providing the limiting member, an area of a portion from which the air or atmosphere flows into the cooling fin is also limited so that the velocity of the air or atmosphere flow becomes high. By these functions and the like, the cooling efficiency of the cooling fin can be increased as compared to the prior art.Type: GrantFiled: December 21, 2006Date of Patent: April 7, 2009Assignee: Hitachi Industrial Equipment System Co.Inventors: Masayuki Hirota, Satoshi Ibori, Tomoya Kamezawa, Jiangming Mao, Masahiro Hiraga

Patent number: 7515413Abstract: A fan device includes a connector, a fan, and an attachment assembly. The fan is configured to provide cooling to circuitry when the fan receives a power signal through the connector. The attachment assembly is configured to control attachment of the fan device to a chassis within an air duct defined by the chassis. The fan defines (i) a near side which faces the circuitry, (ii) a far side which faces away from the circuitry, (iii) an airflow axis which extends from the near side to the far side along an airflow direction, and (iv) a fan profile which is substantially perpendicular to the airflow axis. The fan is disposed substantially between the electronic circuitry and the attachment assembly when the fan device attaches to the chassis within the air duct. The attachment assembly has a width which closely mirrors that of the fan profile.Type: GrantFiled: April 27, 2007Date of Patent: April 7, 2009Assignee: Cisco Technology, Inc.Inventor: George Curtis

Patent number: 7508664Abstract: An assembly that facilitates the use of modules requiring orthogonal airflow in a chassis providing normal airflow. Partitions within the housing direct ambient airflow from the front air inlet, through the modules, and out the rear air exhaust. The housing and partitions define first and second vertically and horizontally offset slots for receiving first and second orthogonal airflow modules, and also define separate first and second airflow pathways. The first airflow pathway provides airflow through a front air inlet, under the second module, orthogonally through the first module and out the rear air exhaust. Similarly, the second airflow pathway provides airflow through a front air inlet, over the first module, orthogonally through the second module and out the rear air exhaust. Both airflow pathways both draw ambient air into the housing and exhaust warm air from the rear of the housing, while keeping the two airflow pathways separated.Type: GrantFiled: July 28, 2006Date of Patent: March 24, 2009Assignee: International Business Machines CorporationInventor: William Gavin Holland

Patent number: 7508066Abstract: A heat dissipating semiconductor package and a fabrication method thereof are provided. A semiconductor chip is mounted on a chip carrier. A heat sink is mounted on the chip, and includes an insulating core layer, a thin metallic layer formed on each of an upper surface and a lower surface of the insulating core layer and a thermal via hole formed in the insulating core layer. A molding process is performed to encapsulate the chip and the heat sink with an encapsulant to form a package unit. A singulation process is performed to peripherally cut the package unit. A part of the encapsulant above the thin metallic layer on the upper surface of the heat sink is removed, such that the thin metallic layer on the upper surface of the heat sink is exposed, and heat generated by the chip can be dissipated through the heat sink.Type: GrantFiled: November 3, 2005Date of Patent: March 24, 2009Assignee: Siliconware Precision Industries Co., Ltd.Inventors: Chien-Ping Huang, Chih-Ming Huang
