A tray-type fan impeller structure includes a plate body annularly disposed around a hub. The plate body has a connection side connected with the hub and a free side extending in a direction away from the hub. Multiple boss bodies are arranged on a top face or the top face and a bottom face of the plate body at intervals. By means of the boss bodies, the periodical noise problem caused by the conventional blades is improved.

Tray-type fan impeller structure

A disk-shaped fan impeller structure includes a plate body having an inner rim and an outer rim. The inner rim is connected with a hub via multiple connection members. The outer rim extends in a direction away from the hub. The connection members are annularly disposed on outer circumference of the hub at intervals to radially extend toward the inner rim of the plate body. A top face and a bottom face are defined between the inner rim and outer rim. Multiple upper boss bodies are arranged on the top face at intervals. Multiple first gaps are distributed between the upper boss bodies. By means of the boss bodies, the periodical noise problem of the conventional fan impeller can be improved.

A fan blade with improved structure includes a hub, a plurality of blades. The hub has a lateral side having two ends, one of which is formed a top side and the other end is extended to form an extended section, and a plurality of connecting slots located on the periphery of the extended section. Each blade has a first end correspondingly engaged in respective connecting slot and a second end. With these arrangements, the fan blade with improved structure can increase structural strength of thin fan blades and be easy to connect the hub to the blades.

An anti-press fan structure includes a fan frame and a fan impeller. The fan impeller has a support shaft supporting the fan impeller disposed in the fan frame. The support shaft has a protrusion section protruding from the fan frame to bear and connect with an external unit positioned above the fan impeller so as to keep an axial space between the fan impeller and the external unit. Accordingly, the fan impeller is prevented from being compressed by the external unit and the pressure applied to the fan frame is dispersed.

A fan wheel structure includes a hub provided with a plate member and a plurality of blades. The plate member is located around the hub and has an upper side and a lower side. The blades are arranged on the upper side of the plate member and respectively have a connecting end connected to the hub as well as a free end. The blades respectively include a backward-curved section, a middle section and a forward-curved section. The backward-curved section is located adjacent to the connecting end and connected to the upper side of the plate member; the forward-curved section is located adjacent to the free end; and the middle section is connected at two opposite ends to the backward-curved section and the forward-curved section. And, an air passage is formed on the upper side of the plate member between any two adjacent backward-curved sections.

The present invention relates to an improved structure of fan blades, which comprises a hub, a connecting part, and a plurality of fan blades. The connecting part has a coupling section and a plurality of slits. The connecting part is sleeved around the perimeter of the hub through the coupling section. The slits are circularly disposed close to the perimeter of the connecting part. The fan blades individually have a first end and a second end; the first ends are individually embedded in the slits and combined with the connecting part. Be means of the present invention, the disadvantage of the combination through a non-integrated structure of the fan blades and the hub in the prior art can be overcome.

Structure of fan blades

A fan impeller structure of cooling fan includes a blade assembly and a hub. The blade assembly has multiple blades and an annular cover body. The annular cover body is integrally formed on the rear ends of the blades by injection molding to enclose and connect with the rear ends of the blades. Alternatively, the annular cover body is fused and integrally connected with the rear ends of the blades by means of laser welding. The blade assembly and the hub are integrally connected with each other to form the fan impeller structure.

Fan impeller structure of cooling fan

A fan rotor mechanism includes a fan impeller, a case and an adhesive body. The fan impeller has a hub and multiple fan blades. The hub has a first top section and a first peripheral section together defining a receiving space for receiving the case. The case has a receptacle for receiving therein at least one magnetic component. The case and the magnetic component define therebetween a filling gap. The case is formed with at least one perforation in communication with the filling gap. The adhesive body is filled up in the filling gap. By means of the structural design of the fan rotor mechanism, the fan rotor mechanism is applicable to various magnetic components with different sizes. Therefore, is unnecessary to manufacture different sizes of molds for different sizes of cases so that the fan rotor mechanism has high universality and is manufactured at lower cost.

The present invention relates to a fan wheel structure comprising a cover body connected with a plurality of fan blades, a hub, and a plurality of fan blades. The cover body is disposed on a hub. The hub has a top surface and a receiving space defined on the top surface. Each of the fan blades has a joining end protruding into the receiving space. The cover body has a clamping side combined with the top surface of the hub and a plurality of joining grooves spaced around the cover body and individually combined with the corresponding joining ends of the fan blades to fix the fan blades.
