The fan frame of the fan is internally provided with a middle pipe, the shaft core of the fan blade is sleeved in a bearing fixed in the middle pipe, and the fan blade is arranged in the fan frame; the fan frame is a plastic fan frame, the metal ring is integrally formed with the plastic fan frame through rubber coating and injection molding, the metal ring is located in the circular inner wall of the plastic fan frame with the outer diameter of the fan blade, rubber passing holes are distributed at equal intervals on the annular peripheral surface of the metal ring, positioning convex ribs and/or anti-sliding grooves are/is arranged on the upper ring opening and the lower ring opening of the metal ring, and the middle pipe is a copper middle pipe. The metal ring is made of metal materials such as iron and aluminum, and is placed into a fan frame mold to be subjected to rubber coating and injection molding after being processed in a die casting mode, turning mode and the like on a machine tool or a die casting mold to be manufactured into a finished fan frame.
Description
Technical Field
The utility model relates to a radiator fan is a novel metal ring fan frame fan.
Background
The heat dissipation fan generally refers to a fan used for heat dissipation of main board devices such as a CPU and a graphics card, and some of the heat dissipation fans are further provided with heat dissipation fins, and mainly aim at conducting heat out and blowing the heat to nearby air to achieve a cooling effect. With the development of society and the change of environment, the field of application of the current electronic products is more and more extensive, the equipment installed on the electronic products is more and more precise, and the cooling fan is applied to equipment such as a server. Since the server generates a large amount of heat and the components are dense, the fan is required to provide high static pressure and large flow, and the high static pressure and large flow fan is accompanied by high power consumption and high noise, which requires improvement of the roundness of the inner diameter of the fan frame, thereby improving the efficiency of the fan and reducing the noise of the fan. Meanwhile, the internal space of the system is compact, so that the requirement on the compressive strength of the fan frame is higher; however, the cost of the conventional aluminum fan frame is high, and the common plastic outer frame cannot achieve the using effect. Therefore, the fan frame of the existing cooling fan needs to be improved, so that the inner diameter of the fan frame can reach the roundness, and the fan frame has the effects of high static pressure and large flow.
Disclosure of Invention
In order to overcome the defects, the utility model aims to provide a novel metal ring fan frame fan to the field, so that the current like product structural design of which is not good enough leads to the roundness to be lower, the high static pressure and the large-flow effect are relatively poor, and the radiating effect is relatively poor. The purpose is realized by the following technical scheme.
A new kind of metal ring fan frame fans, there is middle tube in the fan frame of the fan, the axle core of the flabellum is emboliased and fixed in the bearing in the middle tube, the flabellum is set up in the fan frame; the fan frame is a plastic fan frame, the metal ring is integrally formed with the plastic fan frame through rubber coating and injection molding, and the metal ring is positioned in the circular inner wall of the plastic fan frame with the outer diameter of the fan blade. Therefore, the metal ring is fixed in the plastic fan frame in an encapsulating way, the metal ring is made of metal materials such as iron and aluminum, and the metal ring is placed in a fan frame mold to be processed into a finished fan frame after being processed in a machine tool or a die-casting mold in a die-casting, turning and other modes.
The annular circumferential surface of the metal ring is provided with glue passing holes distributed at equal intervals. The structure enables the metal ring and the plastic fan frame to be further integrally fixed and formed.
And the upper and lower ring openings of the metal ring are provided with positioning convex ribs and/or anti-slip grooves. The structure ensures that the metal ring and the plastic fan frame are integrally fixed and formed to be further stable.
The middle pipe is a copper middle pipe. Thereby further improving the heat dissipation effect of the fan.
The utility model has reasonable structural design, higher roundness of the fan frame, good high static pressure and large flow effect, good firmness and stability and long service life; the fan frame is suitable for production and use of a large fan frame of a cooling fan and further improvement of similar products.

Detailed Description
The structure and use of the present invention will now be further described with reference to the accompanying drawings. As shown in fig. 1-3, a middle tube 3 is arranged in a fan frame of the fan, the middle tube is a copper middle tube, a shaft core of the fan blade is sleeved and fixed on a bearing in the middle tube, and the fan blade is arranged in the fan frame. The fan frame is a plastic fan frame 1, the metal ring 2 is integrally formed with the plastic fan frame through encapsulation and injection molding, and the metal ring is located in the circular inner wall of the plastic fan frame with the outer diameter of the fan blade. The annular peripheral surface of the metal ring is provided with glue passing holes 201 which are distributed at equal intervals, and the upper and lower ring openings of the metal ring are provided with positioning convex ribs 202 and anti-slip grooves 203. The metal ring rubber is fixed in the plastic fan frame and integrally formed through rubber coating and injection molding, and the metal ring is made of metal materials such as iron and aluminum.
To sum up, the technology for improving the roundness of the inner diameter of the fan frame in the industry at present mainly adopts the technologies of an aluminum fan frame, a multi-sliding block die fan frame and the like, but the aluminum fan frame has high cost and cannot meet the requirement of customers on price; the mold cost of the multi-slide block mold fan frame is high, the production efficiency is low, and the improvement effect is not good enough. According to the fan frame structure of the fan, the metal ring is encapsulated in the mould in the fan frame, so that the problems of shrinkage deformation and poor roundness during injection molding of the inner diameter of the plastic fan frame can be effectively solved, the efficiency of the fan is improved, the noise of the fan is reduced, and the roundness of the inner diameter and the outer diameter of the fan frame is effectively improved; meanwhile, the metal ring coated with the rubber enhances the compressive strength of the fan frame, effectively improves the stability of the fan, and is a novel fan frame structure.
