Patent number: 7990717Abstract: An electronic device includes a shell, an electronic component received in the shell, and a heat sink arranged between the electronic component and the shell. The heat sink includes a first heat spreader attaching to the electronic component, a second heat spreader spaced from the first heat spreader, and a plurality of fins between the first and second heat spreaders. Each fin includes a pair of contacting portions, a pair of bending portions and a connecting portion each of which being flat. The contacting portions are respectively connected to the two heat spreaders. The bending portions respectively extend from the contacting portions towards each other. Each bending portion forms a rear end adjacent to the other bending portion. The connecting portion interconnects the rear ends of the bending portions at opposite ends thereof.Type: GrantFiled: July 17, 2009Date of Patent: August 2, 2011Assignees: Furui Precise Component (Kunshan) Co., Ltd., Foxconn Technology Co., Ltd.Inventors: Xi-Jian Zhu, Ran Lin

Publication number: 20070089869Abstract: A heat sink (10) includes a plurality of fins (12). Each of the fins includes a main body (122) and at least one bulge (126) disposed on the main body. The main bodies of two adjacent fins cooperatively define an air passage (121) therebetween, for allowing an airflow to pass therethough. The bulge has a varying projection height so as to form a streamline guide surface (127) thereon.Type: ApplicationFiled: June 15, 2006Publication date: April 26, 2007Applicant: FOXCONN TECHNOLOGY CO., LTD.Inventors: Ching-Bai Hwang, Xi-Jian Zhu

Publication number: 20060292020Abstract: A cooling fan includes a motor (30) for generating an airflow, and a housing (10) defining a space (40) for receiving the motor therein. The housing defines an air inlet (57) through which the airflow flows into the housing. The motor has a plurality of fan blades (31) extending radially outwards from a periphery thereof. The motor is mounted under the air inlet. The air inlet is so configured or positioned that the fan blades are unevenly exposed to an ambient air through the air inlet. The housing further has an air outlet (56) through which the airflow flows out of the fan. The air outlet is oriented perpendicular to the air inlet.Type: ApplicationFiled: March 14, 2006Publication date: December 28, 2006Inventors: Ching-Bai Hwang, Xi-Jian Zhu, Guo-Wen Zhang

Patent number: 7080973Abstract: A fan seat (30, 30?) includes a basis (31) with a vertical extending tubal portion (32) having a pair of flanges (33) integrally formed on opposite ends of an inner circumferential surface thereof, and a bearing set (34, 34?) located in the tubal portion and sandwiched between the flanges. The bearing set includes a tube (36) and a pair of bearings (38) firmly secured in opposite ends of the tube. A method for producing the fan seat includes the following steps: providing a mold (50) with a cavity (53), locating the bearing set in the cavity with a space (60) formed between the bearing set and the mold corresponding to the tubal portion, injecting molten material into the space, and cooling the molten material whereby the molten material congeals into the tubal portion and integrates with the tube.Type: GrantFiled: July 15, 2004Date of Patent: July 25, 2006Assignee: HON HAI Precision Industry Co., Ltd.Inventors: Chao-Nien Tung, Xi-Jian Zhu

Publication number: 20060144567Abstract: A pulsating heat transfer apparatus includes a number of separate heat receiving portions (100, 200, 300), at least one heat dissipating portion (400), and a plurality of capillary pipes (500). Each heat receiving portion has a flat surface for contacting with a heat source, and defines therein at least one first capillary passage. Each heat dissipating portion defines therein at least one second capillary passage. The first capillary passages, the at least one second capillary passage, together with the capillary pipes form a close-looped, serpentine flow channel having capillary effect. Vapor slugs (600) and liquid slugs (700) are distributed in the flow channel. Heat is capable of being transferred from the heat receiving portions to the at least one heat dissipating portion by pulsation of the vapor slugs and liquid slugs.Type: ApplicationFiled: August 23, 2005Publication date: July 6, 2006Applicant: Foxconn Technology CO., LTD.Inventors: Xi-Jian Zhu, Ching-Bai Hwang
