Heat-dissipating device having air-guiding cover

Abstract

A heat-dissipating device having an air-guiding cover includes a heat-dissipating body, an air-guiding cover, a plurality of heat pipes, a fixing base and a fan. The heat-dissipating body is constituted of a plurality of heat-dissipating pieces that are stacked up at intervals. On the heat-dissipating body, venting channels and a plurality of through holes are provided. The air-guiding cover includes a hollow cylinder and an air-guiding blade. The hollow cylinder covers the heat-dissipating body. The air-guiding blade is accommodated in the venting channel. Each of the plurality of heat pipes includes a section to be heated and a heat-releasing section extending from the section to be heated. The heat-releasing section penetrates into the through hole. The bottom of the fixing base is provided with a plurality of grooves for accommodating the sections to be heated of the heat pipes. The fan is provided above the air-guiding cover. Via the above arrangement, the air-guiding cover guides the airflow blown by the fan, thereby enhancing the heat-dissipating effect.
