Abstract
A fan testing apparatus includes an air duct defining an air inlet and air outlet, and at least one anemometer mounted at the air outlet. The fan is received in the air duct to generate airflow in the air duct via the inlet and out of the air duct via the outlet, and the at least one anemometer is used to measure wind speed at the outlet.
Claims6
A fan testing apparatus comprising:
- a hollow air duct defining an air inlet and an air outlet respectively located at two opposite ends thereof;
- at least one anemometer mounted to the air duct adjacent to the air outlet to measure a speed of the airflow generated by a fan mounted in the air duct;
- wherein an access hole is defined in the air duct, adjacent to the air inlet of the air duct, for the fan inserted into or take out of the air duct;
- and
- wherein opposite guide rails are attached to insides of the air duct, aligned with the access hole.

A fan testing method comprising:
- providing a fan testing apparatus comprising:
- an air duct defining an air inlet, and an air outlet;
- and
- at least one anemometer mounted to the air duct adjacent to the air outlet;
- mounting a reference fan into the air duct;
- powering on the reference fan to generate an airflow entering the air duct through the air inlet, and out of the air duct through the air outlet;
- obtaining a speed Va of the airflow generated by the reference fan, through the air outlet with said at least one anemometer;
- taking the reference fan out of the air duct, and mounting a to-be-tested fan into the air duct instead;
- powering on the to-be-tested fan to generate an airflow entering the air duct through the air inlet, and out of the air duct through the air outlet;
- obtaining a wind speed Vb of the airflow generated by the to-be-tested fan, through the air outlet with said at least one anemometer;
- comparing the speed Vb with the speed Va, if the speed Vb is greater than or equal to the speed Va, the to-be-tested fan is eligible;
- if the speed Vb is smaller than the speed Va, the to-be-tested fan is ineligible.
