Abstract
A heat-dissipating device includes a heat-dissipating body, a vapor chamber and a fan assembly. The heat-dissipating body includes a thermal-conductive element and a radial fin assembly. The thermal-conductive element includes a solid post and extending arms extending therefrom. The radial fin assembly includes radially-arranged heat-dissipating fins that form a central hole to enclose the sold post, engaging troughs inserted by the extending arms, and an airflow space. An air channel is formed between any two heat-dissipating fins. The vapor chamber is provided at one end of the solid post, while the fan assembly is arranged on the other end and received in the airflow space to correspond to the respective air channels. Thus, the mobility of air and the heat-dissipating efficiency can be increased, thereby conforming to the requirements for compact design.
