Abstract
A fan accessory includes an air-inlet piece configured to be disposed in front of a fan and has a first hole adjacent to an outside and a second hole adjacent to the fan. The first hole is in communication with the second hole. The first hole has a first diameter gradually decreased in an airflow direction from the outside to the fan, and the second hole has a second diameter gradually increased in the airflow direction. The fan accessory also includes an air-outlet piece configured to be disposed behind the fan and have a third hole. The third hole has a third diameter gradually decreased in the airflow direction.
Claims18
