Patent number: 7330355Abstract: A fixed pillar with heat loss is a fixed pillar for losing heat. The fixed pillar with heat loss includes a metal body, a screw thread and a plurality of grooves. The metal body is a hollow body. The plurality of grooves is respectively set on two sides of the metal body and communicating with each other. The screw thread is set on one end of the metal body to fix a circuit or other electric devices. Air flows into one side of the metal body and then passes through the inner part of the metal body and last flow out from another side of the metal body. Accordingly, the metal body exchanges heat with the air to lose the thermal energy quickly.Type: GrantFiled: April 14, 2005Date of Patent: February 12, 2008Assignee: Via Technologies Inc.Inventors: Yi-Cheng Kuo, Chi-Chang Chang, Cheng-Ming Hsu

Patent number: 7327575Abstract: A locking device (10) for securing a heat sink (20) to a heat generating component (30) includes a pair of operating members (14) and a pair of locking members (16). Each operating member includes a pivot shaft (142) defining an axis and an operation handle (144) extending from the pivot shaft along a first direction. The pivot shaft has an offset section (146) offsetting from the axis thereof in a second direction. The first direction and the second direction form an angle therebetween. Each locking member is attached to the offset section of one of the operating members. The operation handle of each operating member is capable of rotating about the axis of the pivot shaft from an unlocked position to a locked position and accordingly the offset section of the pivot shaft drives the locking member to move upwardly.Type: GrantFiled: February 18, 2005Date of Patent: February 5, 2008Assignees: Fu Zhun Precision Industry (Shenzhen) Co., Ltd., Foxconn Technology Co., Ltd.Inventors: Fang-Xiang Yu, Shu-Ho Lin, Meng-Tzu Lee

Patent number: 7327573Abstract: A heat sink clip (1) includes a main body (10), a post (40), a spring (50) and a cammed handle (30). The main body includes a horizontal portion (12) and two locking arms (16). A locking hole (17) is defined in an end of each locking arm for engaging with catches (82) of a socket (80). The post has a pressing block (44) at a bottom portion and a cutout (42) at a top portion. The spring is placed around the post and rests on the pressing block The post extends through a through aperture (13) of the horizontal portion, and the cutout pivotally receives a cam (32) at one end of the handle. When the handle is pressed, the horizontal portion of the main body is raised by the decompressed spring, so that the locking arms tightly engage with the catches of the socket.Type: GrantFiled: July 25, 2003Date of Patent: February 5, 2008Inventors: Hsieh Kun Lee, Wellint Xia, Toly Lee, Gen-Cai Wang

Patent number: 7317618Abstract: An exemplary apparatus generally includes a fence, a heat sink, and a thermal interface. The fence includes walls defining at least one opening along an upper portion of the fence. The walls are configured to be disposed generally about one or more electrical components of a board. The heat sink includes resilient fingers connected to a lid portion, and configured to engage openings of the fence and/or the board. The lid portion is configured to substantially entirely cover the at least one opening of the fence for cooperatively shielding the one or more electrical components within the interior defined by the lid portion and the fence's walls. The thermal interface is configured such that engagement of the resilient fingers with the openings compresses the thermal interface between the lid portion and the one or more electrical components, thereby forming a thermally-conducting heat path from the one or more electrical components to the heat sink.Type: GrantFiled: May 1, 2006Date of Patent: January 8, 2008Assignee: Laird Technologies, Inc.Inventors: Kenneth M. Robinson, James E. Kline
