Abstract
A cooling fan with high heat-dissipating performance includes a plurality of blades; and a frame for receiving the blades therein, wherein the frame has a reduced height for exposing the blades to outside of the frame so as to allow air to enter into the frame via a top portion and a peripheral portion of the blades to improve air introduction and heat dissipating efficiency of the cooling fan. A cover may be mounted to a top surface of the frame, and formed with a plurality of openings for allowing air to enter into the frame through the openings; such an arrangement cam effectively enhance air intake and working efficiency of the cooling fan.
Claims21
A cooling fan comprising:
- a plurality of blades;
- and
- a frame for receiving the blades therein, wherein a height of the frame is reduced to an extent for exposing the blades so as to allow air to enter into the frame via a top portion and a peripheral portion of the blades to improve air introduction and heat dissipating efficiency of the cooling fan.
A cooling fan comprising:
- a plurality of blades;
- and
- a frame for receiving the blades therein, wherein the frame has a hollow portion for disposing the blades in the frame, and a plurality of openings formed on peripheral areas thereof for allowing air to enter into the frame through the hollow portion and the plurality of openings so as to improve heat-dissipating performance of the cooling fan.
