Heat Dissipator
A heat dissipator for mounting on a heat-generating element includes a heat-dissipating body, a fan assembly, a bottom stand and a top stand. The heat-dissipating body is formed into a spherical body and constituted of a plurality of heat-dissipating pieces. The heat-dissipating body is provided with a sealed accommodating space therein for accommodating the fan assembly. Further, the bottom stand and the top stand are provided at the upper and lower ends of the heat-dissipating body, respectively. Further, the bottom of the fan assembly has a connecting seat for connecting to the bottom stand to fix the fan assembly. Finally, the bottom stand is provided with a heat-conducting block for adhering to the heat-generating element, thereby to conduct the heat generated by the operation of the heat-generating element to the heat-dissipating body. In this way, the heat can be uniformly dissipated to each heat-dissipating piece. With the airflow generated by the fan assembly, the heat-dissipating effect can be satisfactorily achieved.
