Abstract
A fan includes a frame and an impeller. The frame includes a main body, a plurality of guiding elements and a motor base. The main body has an airflow inlet and an airflow outlet. The guiding elements are disposed in the main body and located at the airflow outlet, wherein each of the guiding elements includes an inclined part and an axial extended part, and the inclined par meets the axial extended part at an angle. The motor base connects to the main body. The impeller is disposed on the motor base for providing an airflow, wherein the guiding elements guide the airflow away from the fan.
Claims15
A frame, comprising:
- a main body having an airflow inlet and an airflow outlet;
- and
- a plurality of guiding elements disposed in the main body and located at the airflow outlet, wherein each of the guiding elements comprises an inclined part and an axial extended part, and the inclined part meets the axial extended part at an angle;
- wherein the inclined part has a first height, the axial extended part has a second height, and a ratio of the first height to the second height is between 0.2 and 5;
- wherein the axial extended part of each of the guiding elements guides airflow away from the frame in a direction perpendicular to a radial direction of the airflow outlet, and the axial extended part is parallel to a vertical direction of the airflow outlet, and
- wherein the sum of the first height and the second height exceeds 15 millimeters when the frame is sized as 38×38 millimeters.
