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

[0017] see figure 1 and figure 2 , is a thin fan 100 according to an embodiment of the present invention, which includes a fan frame 10 and a fan blade 20 accommodated in the fan frame 10 . The thin fan 100 is clamped and fixed on a related electronic device (not shown), so as to assist the electronic device to dissipate heat.

[0018] Please also see image 3 and Figure 4 The fan frame 10 includes an upper cover 11 , a lower cover 12 , a scroll side wall 13 connected between the upper cover 11 and the lower cover 12 , and a connecting portion 14 extending from the side edge of the scroll side wall 13 . The side wall 13 is formed integrally extending downward from the outer periphery of the upper cover 11 , and the upper cover 11 , the lower cover 12 , the side wall 13 and the connecting portion 14 enclose to form a receiving space 15 for accommodating the fan blade 20 .

[0019] Specifically, the upper cover 11 and the lower cover 12 are in the shape of a flat plate and...

Abstract

A thin fan comprises a fan frame and a blade assembly accommodated in the fan frame. The fan assembly comprises a hub, a blade ring structure around the hub and a plurality of blades clamped on the blade ring structure, and the blades are made of magnesium and aluminum alloy. The thickness of the fan is reduced greatly as compared with that of the prior art, so that the thin fan has larger air intake space and high in airflow and cooling effect of the thin fan is guaranteed. Besides, since the blades of the fan are thinned, the integral size of the blades is reduced, and weight of the blades is lower than that of existing plastic blades. Further, due to excellent performance of the magnesium and aluminum alloy blades, stress of the blades is improved, the blades are not easy to deform. In addition, since interference between the blades and a top cover is avoided, stability of the thin fan is improved.

Description

technical field [0001] The invention relates to a fan device, in particular to a thin fan used for heat dissipation of electronic products. 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] A thin fan generally includes a fan frame and fan blades accommodated in the fan frame, and 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 thi...
