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 cooling fan (100) includes a frame (10), a circuit board (20) and a rotor (30). The frame includes a housing (12) and a plate (14) connecting with the housing. The circuit board is mounted on the plate. The rotor is received in the housing and includes a hollow hub (32) and a plurality of blades (38) extending from the hub. A plurality of light emitting diodes (40) is mounted on the circuit board. When the rotor rotates, each LED projects light towards the rotor and to the frame so that the light will be reflected and deflected by the fan whereby the whole fan glows and produces a fantastic visual effect.
Abstract:
A cooling fan includes a hub (40) and blades (50) extending radially from the hub. Each of the blades is divided into strip zones (505, 51, 52, 53, 54, 55, 56), projections of homocentric arcs concentric with the hub on the blades are defined as boundaries of the zones. The zones are coated with a layer of paint with different colors to present a rainbow-liked image when the fan is in operation.
Abstract:
A heat sink includes a first array of fins defining a plurality of first channels therebetween, a second array of fins disposed at opposite sides of the first array of fins, and a plurality of grooves extending through the first array of fins and the second array of fins. The second array of fins defines a plurality of second channels therebetween. The grooves are intersected with the first channels and the second channels. A bottom extremity of each groove has a curved shape facing upwardly and laterally. A portion of an airflow generated by a fan mounted on a top of the heat sink flows laterally and downwardly through the grooves to leave the heat sink.
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 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 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.
Abstract:
A heat dissipation device includes a heat sink, a fan placed on a top of the heat sink for providing an airflow through the heat sink and a fan duct located at a side of the heat sink. The heat sink includes a plurality of upwardly extending first fins and a plurality of laterally extending second fins located below the first fins. A plurality of first airflow channels are defined in the adjacent first fins and a plurality of second airflow channels are defined in the adjacent second fins. The fan duct guides a significant part of the airflow produced by the fan to the second airflow channels from a lateral side of the heat sink to have a sufficient contact with the second fins of the heat sink.
