Abstract:
A cooling fan includes a frame, a stator, a rotor and a display panel. The frame includes a base. The stator is mounted on a bottom surface of the base. The rotor is rotatably installed on the stator and received in the frame. The display panel is attached to a top surface of the base and electrically connected to the stator. The display panel can show a lot of useful information such as a logo of the cooling fan, a rotating speed of the cooling fan and an environment temperature.
Abstract:
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.
Abstract:
A heat sink used to dissipate a heat source includes a heat-dissipating portion and a heat-conducting portion secured into the heat-dissipating portion. The heat-dissipating portion includes a base and fins extending from the base. The base defines a threaded hole in a bottom thereof. The heat-conducting portion includes a substrate for contacting with the heat source and a threaded portion extending from the substrate. The threaded portion of the heat-conducting portion is positioned in the base of the heat-dissipating portion and secured in the base of the heat-dissipating portion by the threaded portion engaging in the threaded hole of the base of the heat-dissipating portion.
Abstract:
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.
Abstract:
A fan assembly includes a fan and a fan guard mounted on the fan to protect the fan from contamination and damage during operation. The fan includes a plurality of ears extending outwardly from a circumference thereof. The fan guard includes a frame and a hood made of net and mounted over the frame in a stretched manner. The frame includes a plurality of concentrically arranged annular ribs and a plurality of supporters connecting the annular ribs together. The annular ribs are spaced apart with predetermined spacing along an axial direction. A lowest one of the ribs of the frame is bent to form a plurality of fastening feet for extension of screws to threadedly engage with the ears of the fan. The hood has an outwardly convex periphery due to the configuration of the annular ribs.
Abstract:
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.

Abstract:
A liquid cooling device (1) includes a base (2) enclosing working fluid therein and absorbing heat from a heat-generating electronic component, a heat sink (10) fluidically connecting with the base, and a pump (3) driving the working fluid to circulate between the base and the heat sink. The heat sink has closed top and bottom ends, and includes an outer tube (100) and an inner tube (30) disposed in the outer tube. First and second receiving chambers (34, 14) are respectively formed in the inner tube and between an inner surface of the outer tube and an outer surface of the inner tube for receiving the working fluid therein. The first receiving chamber communicates with the second receiving chamber at an end thereof so that the working fluid flows from the first receiving chamber to the second receiving chamber.
