Hybrid fluid-dynamic apparatus

Abstract

The present invention is to provide a hybrid fluid-dynamic apparatus which is an assembly of an axial fan and a centrifugal fan. The assembly apparatus is able to enhance the volume of airflow and the air pressure of the centrifugal fan. The hybrid fluid-dynamic apparatus includes a first dynamic device, a second dynamic device, and an air path between the first and second dynamic devices; wherein the first dynamic device comprises a axial impeller, the second dynamic device comprises a centrifugal impeller, the air path is gradually narrowed from the first dynamic device to the second dynamic device. The air is able to be directed to the air path by the first dynamic device and exhausted by the second dynamic device. Thus, the hybrid fluid-dynamic apparatus is capable to increase the airflow volume and air pressure to enhance the efficiency of the heat dissipation.
