Heat-conducting plate is installed, the fan housing and fan back cover are bolted on the upper surface of radiator ontology, and wind
The inside of fan outer cover is equipped with miniature motor, and shaft and the oil-containing axle center of the miniature motor are fixedly welded, and flabellum is logical
It crosses noise reduction axle sleeve to be mounted on oil-containing axle center, the front and rear sides of the flabellum are respectively arranged with flexible ring set and rear door, described
Leaf cover is installed, and oil-containing axle center is mounted on leaf cover by fastening nut on fan housing, the mute bottom plate, fan housing
Fabrics abatvoix and polyester fibre acoustic panel are fixed with on the inner wall of fan back cover.
Preferably, end cap is provided on outside on the fastening nut.
Preferably, location hole is provided on the mute bottom plate.
Preferably, described this body side surface of radiator is provided with thermally conductive copper bar.
Compared with prior art, the beneficial effects of the present invention are: the equipment is ingenious in design rationally, outside mute bottom plate, fan
It is fixed with fabrics abatvoix and polyester fibre acoustic panel on the inner wall of cover and fan back cover, can greatly absorb fan institute
The noise of sending, and it is internally provided with heat-conducting plate in radiator ontology, timely thermally conductive copper bar can be transmitted
Heat is discharged into air, and computer is discharged in hot gas by fan therewith, and is provided with and is disappeared between motor and flabellum
Sound axle sleeve, even if in the case where the oil starvation of axle center fan will not with axle center generate friction generate noise.
