Abstract
A heat-dissipating device includes a housing having an air inlet and an air outlet, and a blade structure disposed in the housing and having a hub and a plurality of rotor blades. The housing has an inwardly extending sidewall to define an accelerating airflow passage between the sidewall, the hub and the rotor blades for effectively increasing the airflow pressure and stabilizing the discharged airflow.
