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.

Heat sink and electronic device using same

A fan seat (') includes a basis () with a vertical extending tubal portion () having a pair of flanges () integrally formed on opposite ends of an inner circumferential surface thereof, and a bearing set (&#x2032;) located in the tubal portion and sandwiched between the flanges. The bearing set includes a tube () and a pair of bearings () firmly secured in opposite ends of the tube. A method for producing the fan seat includes the following steps: providing a mold () with a cavity (), locating the bearing set in the cavity with a space () 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.

Fan seat and method for producing it

A fan ( ) includes a housing ( ), a vane assembly ( ), and a sealing device ( ). The housing includes a base portion ( ), a bearing sleeve ( ), a self-lubricating bearing ( ) received in the bearing sleeve, and a lubricant insulation ring ( ) received in the bearing sleeve. The vane assembly is rotatably attached in the housing, with a central rod ( ) of the vane assembly extending through the bearing and the lubricant insulation ring. The sealing device is attached to the base portion such that the bearing is sealed in the bearing sleeve between the lubricant insulation ring and the sealing device. A sealing ring ( ) of the sealing device is disposed in an annular groove ( ) defined in the base portion, and is pressed tightly between the sealing lid and the base portion.
