20090145580 | Heat sink and a method of manufacturing the heat sink - A heat sink includes a base plate and a plurality of thin-sheet fins. The base plate has a plurality of recesses and protruding ribs formed between every two recesses. The protruding ribs are spaced by the respective recesses with an equal space. Each thin-sheet fin comprises a folded engaging portion and a dissipating portion connecting with the engaging portion. The engaging portion has a first extending portion and a second extending portion parallel to the first extending portion and connecting with the first extending portion. The engaging portions are inserted into the recesses of the base plate and abut against a bottom of the recesses. | 06-11-2009 |
20090147475 | Heat dissipation device having a fan mounted thereon - A heat dissipation device for dissipating heat from a heat-generating electronic element includes a heat sink for contacting with the heat-generating electronic element, a fan placed on the heat sink for providing an airflow through the heat sink and two wire clips. The fan comprises a frame. Each wire clip comprises a V-shaped main body and two locking parts at two opposite ends of the main body. Middles of the main bodies of the two wire clips are securely attached to two lateral sides of the heat sink by two screws. The locking parts of the wire clips are fastened to the frame of the fan, with the main bodies being deformed and pushing the fan toward the heat sink. | 06-11-2009 |

20090161316 | HEAT DISSIPATION DEVICE WITH FAN HOLDER - A heat dissipation device includes a heat sink assembly, a fan holder and a fan mounted in the fan holder. The heat sink assembly includes a heat spreader for contacting with a heat-generating electronic component, and two fin assemblies thermally connecting with the heat spreader and sandwiching the fan therebetween. Each fin assembly defines cutouts at opposite ends thereof. The fan holder includes a top plate and a pair of vertical, downward-extending baffle walls. A pair of clamping arms extends from each baffle wall and inserted into the cutouts of the fin assemblies. Screws extend through the top plate to engage in holes defined in the fin assemblies and communicating with the cutouts. A vaulted operating plate is formed by the top plate for a user to grip to conveniently transport the heat dissipation device. | 06-25-2009 |
20090165998 | HEAT DISSIPATION DEVICE - A heat dissipation device includes a base, a fin group located at a top of the base, a heat pipe connecting with the base and the fin group, a fan located at a top of the fin group, and a fan holder. The fan holder includes a securing portion mounted between the base and the fin group, a mounting portion extending from the securing portion. The mounting portion of the fan holder is located at a top of and spaced from the fin group and the fan is mounted on the mounting portion. | 07-02-2009 |
20090166009 | HEAT DISSIPATION DEVICE HAVING HEAT PIPES FOR SUPPORTING HEAT SINK THEREON - A heat dissipation device includes a base, a fin group located at a top of the base, a fan mounted on a top of the fin group, a first heat pipe and a second heat pipe. The first and second heat pipes connect with the base and the fin group and each includes a condensing portion and an evaporating portion. The evaporating portions of the first and second heat pipes are received in the base. The condensing portions of the first and the second heat pipes are located at opposite sides of the fin group respectively and extend through and support the fin group along opposite directions. | 07-02-2009 |
20090166011 | HEAT DISSIPATION DEVICE HAVING A MOUNTING BRACKET - A heat dissipation device includes a heat sink, a plurality of mounting brackets and a fan. The heat sink comprises a central core, a plurality of branches at a circumference of the core and a plurality of fins extending outwardly from the core and branches. Each of the branches has a locking part at a distal end thereof. Each of the mounting brackets comprises a mounting plate engaging with the locking part, a supporting part extending outwardly from a top end of the mounting part and a fixing part extending outwardly from a bottom end of the mounting plate. The fan is supported and secured on the supporting part. | 07-02-2009 |
20090168350 | HEAT DISSIPATION DEVICE WITH A FAN HOLDER - A heat dissipation device includes a heat sink assembly, a fan holder and two fans mounted on the two sides of the fan holder. The heat sink assembly includes a heat spreader for contacting with a heat-generating electronic component, and a fin assembly thermally connecting with the heat spreader. The fin assembly has a plurality of channels therein. The fan holder includes a top plate mounted on a top of the fin assembly and a pair of vertical baffle walls extending from two opposite ends of the top plate. The baffle walls of the fan holder are located at two lateral ends of the fin assembly and sandwich the fin assembly therebetween. The two fans respectively abut against inlets and outlets of the channels of the fin assembly. An airflow generated by one fan flows through the fin assembly and is sucked by the other fan. | 07-02-2009 |
20090236077 | HEAT DISSIPATION DEVICE - A heat dissipation device for dissipating heat generated by an electronic component includes a base, a pair of fin groups and heat pipes connecting the base with the fin groups. The base is used for thermally contacting with the electronic component. The fin groups includes a plurality of fins located over the base. Each of the heat pipes includes an evaporating portion received in the base, a condensing portion extending spirally and upwardly from an end of the evaporating portion through a corresponding fin group. The fins of each fin group is so arranged that each fin group has an arch-shaped profile. The condensing portions in each fin group are parallel to each other. A fan is mounted over the fin groups. | 09-24-2009 |
