Problems solved by technology

Due to the thick fan blade, it limits the heat dissipation performance of the thin fan to a certain extent. Secondly, under long-term rotation and high temperature environment, the plastic fan blade is prone to deformation, which may cause interference between the fan blade and the upper cover, affecting the thin fan. If the traditional method of reducing the height of the fan blades to avoid interference is adopted, the heat dissipation performance of the thin fan will be further weakened

Embodiment Construction

[0020] The fan device and the method for making the fan blades of the present invention will be further described below with reference to the figures.

[0021] see figure 1 The fan device 10 provided by the embodiment of the present invention includes a fan frame 100 and a fan blade structure 200 accommodated in the fan frame 100 . The airflow generated by the fan device 10 is used to assist the electronic components to dissipate heat.

[0022] Please also refer to figure 2 with image 3 The fan frame 100 includes a bottom plate 110 , a cover plate 120 disposed on the bottom plate 110 , and a side wall 130 extending downward from the edge of the cover plate 120 and connected between the bottom plate 110 and the cover plate 120 . An outwardly extending connecting portion 140 is formed at one end of the side wall 130 close to the bottom plate 110 , and the connecting portion 140 is closely attached to the bottom plate 110 . In this embodiment, the cover plate 120 , the side...

Abstract

A fan blade producing method includes providing a fan blade mould; injecting mixture of metal powder and molten adhesive into the fan blade mould in an injected and formed manner to form a blank of the fan blade; removing the adhesive on the blank of the fan blade; sintering the blank of the fan blade to form the fan blade. Since the fan blade is produced by metal powder in the injected and formed manner, compared with the prior art, the thickness of the fan blade is thin, accordingly a fan device has larger air flow, radiating efficiency is improved; furthermore, since the blade is produced by metal powder, deformation occurs rarely to cause interference between the fan blade and an upper cap, and stability of the fan device is improved. The invention further provides a fan device applying the fan blade.

Description

technical field [0001] The invention relates to a manufacturing method of a fan blade and a fan device using the fan blade. Background technique [0002] With the increasing performance of electronic products, a large amount of heat is also produced. Cooling fans are components that are often used to assist in cooling. [0003] On the other hand, electronic products tend to be smaller in size and lighter in weight, and their thickness is increasingly thinner, such as notebook computers. In order to meet the demand for thinner electronic products, fans must also develop towards thinner. [0004] The fan device generally includes a fan frame and fan blades accommodated in the fan frame. The fan frame includes an upper cover, a lower cover and a side wall connecting the upper cover and the lower cover. Under the thin structure with limited space, how to overcome the fluid resistance, improve the air flow, and ensure the heat dissipation performance of the thin fan has become...
