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.
Claims19
A cooling fan comprising:
- a plurality of blades;
- a frame for receiving the blades therein, wherein a height of the frame is reduced to an extent for exposing the blades, and the frame includes a plurality of air-guiding parts directly extended from corner areas of the frame;
- and
- a cover assembled with the frame through the air-guiding parts, and having a top portion and at least one side plate, wherein the side plate is extended from a peripheral edge of the top portion and vertically bent downwards, the side plate is formed with a plurality of vertical or lateral bars biased with an angle with respect to the side plate such that at least one air intake is formed between the bars therethrough and the side plate abuts against the air guiding part of the frame.
A cooling fan comprising:
- a plurality of blades;
- a frame for receiving the blades therein, wherein the frame comprises at least one air-guiding part directly formed with a periphery of the frame and directly extending from corner areas of the frame, and 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 dissipation efficiency of the cooling fan;
- and
- a cover mounted to the air-guiding part of the frame, wherein the cover is provided with a top portion and a plurality of side plates, the side plates are extended from peripheral edges of the top portion and vertically bent downwards, the side plates abut against the air guiding part of the frame each of the side plates is formed with a plurality of bars and openings in a manner that adjacent openings are spaced by one of the bars, and the cover and the frame are formed as a single piece.
