Abstract: The present invention is a radial fan having an axial fan blade configuration. The present invention comprises a hub; a first set of blades around the hub; and a second set of blades on the extending part. Therein, the hub comprises a hollow at the center, an axle, a guiding part and an extending part. The gaps are each between every two adjacent blades of the second blade set, having the same distance between every two adjacent gaps. The second set of blades comprises a plurality of blades around outside of the first set of blade and a ring connected with the blades. Accordingly, the structure of the blades may increase the wind pressure, reduce the energy loss by the blade rotation and raise the work efficiency of the blades while the noise is lessened and the working current is lowered.

Abstract: The present invention is an axle fixture for heat dissipation fan and a method of manufacture thereof, comprising steps of the followings: obtaining a shell with an axle at center where a depression is deposed on the bottom with several rabbets which are not connected to the axle; providing a lower mold with a platform and a concave where the shell is covered on the platform and the concave is corresponding to the rabbets; obtaining an upper mold with sprue to cover on the shell where the sprue is corresponding to the concave but not to the axle; and pouring a fixing agent from the sprue into the concave with the guidance of the rabbets so that the axle can be firmly fixed at the center of the shell after the fixing agent is solidified. In this way, an axle fixture can be easily manufactured and the cost can be reduced while the axle can be firmly fixed at the center of the shell.

Abstract: The present invention is a hub structure for a heat-dissipation fan, comprising a hub; and a plurality of locking parts. Therein, the hub includes a containing space. The locking parts are at the bottom of the containing space. Each locking part comprises a curved surface, a hook extended to the side wall of the containing space, and a leaning part at the end. Accordingly, by the locking parts, a metal sheath for a fan can be locked to a hub and is firmly fixed in the containing space to prevent from looseness or departure.

Abstract: The present invention relates to a structural reinforcement of the fan wheel of a mixed flow fan. The structure of the fan wheel comprises a hub and several blades attached to the outer rim of this hub. One side of the hub consists of a hollow space, the other side consists of a flat surface. The blades are attached to the outer rim of the hub in equal distances. The outer rim of the hub is beveled. The flat surface acts as the air inlet side, the hollow side acts as the air outlet side. The surfaces of the blades are to bend. The part connecting the blades to the hub is also to bend. Therefore cambered channels form in the gaps between the blades, which are arranged in equal distances. Through use of this structure the operational area for the characteristic curve of the mixed flow fan is increased and the possibility of a loss of speed is reduced. Thus the overall performance of the fan is improved.

Abstract: The modified centrifugal fan wheel comprises a hollow hub and a set of blade. A hollow hub axis is disposed at the center of a hollow portion of the hollow hub. Along a top side surface of the hollow hub is a curved guiding inlet part and along a bottom side surface of the hollow hub is a curved surface with a smooth fillet extending to a closed part. A set of blades is arranged around an outer part of the hollow hub, having an up ring and a down ring. An inner part of the down ring is connected to the closed part of the hollow hub. Blades are disposed between the up ring and the down ring. Wind holes are disposed equidistantly between each of the blades and equidistant perforations are arranged on the surface of the down ring, connecting to the wind holes between each of the blades. By the closed part and the perforation of the fan wheel, low noise and low current are provided. Meanwhile, power consumption is reduced and working performance of the fan wheel is also improved.
