Problems solved by technology

Due to the narrowing of the internal space of the computer and the gap between the upper and lower air intakes of the thin fan, the thickness of the traditional thin fan is severely compressed, and the air flow is not high, resulting in low heat dissipation efficiency; moreover, the traditional thin fan becomes thinner Afterwards, its overall height is reduced, thereby reducing the height of the bearing system, reducing the oil storage capacity of the bearing, and reducing the supporting force of the bearing, which greatly affects the service life of the thin fan

Embodiment Construction

[0018] see Figure 1 to Figure 3 , is a thin fan 100 according to the first embodiment of the present invention, which includes a fan frame 10 and an impeller 20 accommodated in the fan frame 10 . The thin fan 100 can be clamped and fixed on a related electronic device (not shown), so as to assist the electronic device to dissipate heat.

[0019] Specifically, see figure 1 , the fan frame 10 includes a fan base 11 and an upper cover 12 located on the fan base 11 , the fan base 11 and the upper cover 12 enclose a receiving space 13 for accommodating the impeller 20 . The fan base 11 includes a bottom plate 111 , a first side wall 112 extending upward from the edge of the bottom plate 111 , a second side wall 113 , and a third side wall 114 opposite to the second side wall 113 . The bottom plate 111 is in the shape of a square flat plate, and its edge adjacent to the third side wall 114 is inwardly recessed to form a first recess 1111. The first recess 1111 is roughly in the s...

Abstract

A thin-type fan comprises an impeller and a fan frame accommodating the impeller, wherein one side wall of the fan frame is provided with an air outlet, the fan frame also comprises an air inlet, and the air inlet is arranged on the other side wall which is adjacent to the side wall on which the air outlet is arranged. Compared with the prior art, a lateral intake and lateral exhaust structure is adopted, the thin-type fan is arranged on an appropriate position, no air intake space needs to be reserved among the impeller, an upper cover and a soleplate, so that an accommodating space which is formed by the upper cover and a fan base can be adequately utilized, and the air flow of the entire thin-type fan can be enhanced. On the basis of utilizing the thin-type fan, a high bearing system can be provided, oil storage volume of the bearing system can be guaranteed, a longer service life condition can be realized compared with the traditional fan, the supporting capacity of the high bearing system is strong, the stability of the entire thin-type fan can be enhanced, and the heat radiation performance of the entire thin-type fan can be the best.

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 traditional thin fan generally includes a fan frame and an impeller 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. The upper cover and the lower cover are provided with air inlets. , an air outlet is opened on one side of the side wall. Under the thin structure wi...
