Patent number: 7723844Abstract: A heat dissipation device includes a heat sink, a retention module and a locking device for securing the heat sink to the retention module. The heat sink includes a base for contacting with a heat-generating component. The retention module includes a bottom wall and a first spring clip secured at one side thereof. The locking device is pivotably connected to the retention module and includes a second spring clip attached thereon. The heat sink rests on the bottom wall of the retention module with an end thereof being pressed by the first spring clip, and an opposite end thereof being pressed by the second spring clip. The locking device can be at a released position where the locking device is pivotable, so that the heat sink is removable from the retention module, and a locked position where the locking device presses the base of the heat sink.Type: GrantFiled: January 24, 2007Date of Patent: May 25, 2010Assignees: Fu Zhun Precision Industry (Shen Zhen) Co., Ltd., Foxconn Technology Co., Ltd.Inventors: Jin-Song Feng, Song-Shui Liu

Publication number: 20080128110Abstract: A heat sink assembly comprises a heat sink (10) having a plurality of outwardly extending fins (13), a plurality of fasteners (20) and a fan (30) mounted on the heat sink (10) via the fasteners (20). Each of the fasteners (20) comprises a self-tapping screw (25) and a fan holder (22). The fan holder (22) is buckled on the fins (13) and comprises a retaining body (220). The retaining body (220) of each fan holder (22) spans cross each corner of the heat sink (10). A connecting portion (225) extends downwardly from the retaining body (220). The connecting portion (225) abuts against the fins (13) of the heat sink (10). Each self-tapping screw (25) is inserted into a hole (228) defined in the connecting portion (225) and a space between two adjacent fins (13a) of the heat sink (10) to attach the fan holder (22) to the heat sink (10).Type: ApplicationFiled: November 30, 2006Publication date: June 5, 2008Applicant: FOXCONN TECHNOLOGY CO., LTD.Inventors: CHENG-TIEN LAI, CUI-JUN LU, SONG-SHUI LIU

Patent number: 7362573Abstract: A heat dissipation device includes a heat sink having a heat conducting core and a plurality of fins extending from the core. The core has a downward extension portion extending away the fins for contacting a heat generating device. A locking device includes a locking plate defining a central opening accommodating the extension portion of the core of the heat sink therein and has a plurality of locking arms extending from the locking plate. Pluralities of cutouts circumferentially surrounding and communicating with the opening are defined in the locking plate. The extension portion of the core of the heat sink is punched to press the locking plate of the locking device toward the heat sink and have portions thereof engaged in the cutouts of the locking plate of the locking device, whereby the locking device is stably fixed to the heat sink.Type: GrantFiled: April 28, 2006Date of Patent: April 22, 2008Assignees: Fu Zhun Precision Industry (Shen Zhen) Co., Ltd., Foxconn Technology Co., Ltd.Inventors: Cui-Jun Lu, Song-Shui Liu

Patent number: 7292443Abstract: A heat sink mounting assembly includes a retention module having a bottom and a pair of posts extending from the bottom. A heat sink is located on the bottom of the retention module. A clip spans across the heat sink and includes a clamping member having first and second legs releasably engaging with the posts of the retention module, and a pressing member having a first end thereof pivotably engaging with a first end of the clamping member. The pressing member has a pressing portion pressing the heat sink toward the retention module when a second end of the pressing member is depressed to engage with a pair of ears formed at a second end of the clamping member.Type: GrantFiled: October 3, 2006Date of Patent: November 6, 2007Assignees: Fu Zhun Precision Industry (Shen Zhen) Co., Ltd., Foxconn Technology Co., Ltd.Inventors: Cheng-Tien Lai, Cui-Jun Lu, Song-Shui Liu
