FAN DEVICE CAPABLE OF INCREASING AIR PRESSURE AND AIR SUPPLY |
摘要 |
A fan device capable of increasing air pressure and air supply includes a fan frame, a base and a fan wheel. The fan frame has an air inlet side, an air outlet and a flow path which defined by the inner wall of the frame. The base is disposed in the flow path and joined to the inner wall of the fan frame by means of a plurality of elongated fan blade shaped connecting parts being attached to the inner wall of the frame. The fan wheel is movably attached to the base from the air inlet side. The base further includes a main base part and a shoulder part with a streamline contour extending from a lateral side of the main base part to approach the air outlet side of the fan frame such that a concave inward curved surface converging toward a central axis of the base is formed with a tip end is disposed at the central axis to concentrate fluid flow and increase air pressure for eliminating stagnation zone and promoting heat dissipation.
