Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the present invention provides a kind of fan, including: housing, and
At least two impeller being positioned in housing, adjacent two impellers turn to contrary and airflow connection, so that at least partly
The air-flow produced by a wherein wheel rotation can be outside housing be flowed out in the rotation of another impeller.
Specifically, above-mentioned impeller includes the first impeller 3 and the second impeller 4, fan have the first wind district and with the first wind district
The the second wind district being connected, the first wind district and the second wind district are respectively provided with air outlet 8.First impeller 3 is located in the first wind district, and second
Impeller 4 is located in the second wind district.Second impeller 4 and the first impeller 3 turn on the contrary, so that at least partly being rotated by the second impeller 4
And the air-flow produced can be outside housing be flowed out in the first wind district.Namely increase the air output in the first wind district, such as when the first wind
During the high heat producing regions of district's correspondence electronic equipment, the second impeller 4 just can increase the product air quantity of the first impeller 3 by this kind of method,
To meet the heat radiation needs of high heat producing regions.
Further, the diameter of the second impeller 4 in the present embodiment closes less than the diameter of the first impeller 3, its concrete ratio
Depending on system can be according to the quantity of heat production of heat producing regions corresponding to two impellers, if the second impeller 4 correspondence is high heat producing regions, and
One impeller 3 correspondence is low heat producing regions, then the diameter of the second impeller 4 is more than the diameter of the first impeller 3.
Continuing with shown in Fig. 2, housing includes the two cover plates 1 being oppositely arranged and the side plate 2 being located between two cover plates 1,
The side plate 2 in the first impeller 3 and corresponding first wind district limits and forms the first air channel 5, the side plate in the second impeller 4 and corresponding second wind district
2 limit and form the second air channels 6, the second impeller 4 rotate the fraction of generation and flow to the first air channel 5 by the second air channel 6 and enter
And flow out outside housing.In the present embodiment, the first impeller 3 is arranged side by side with the second impeller 4, and side plate 2 at least has respectively around
One impeller 3 and two curved portions of the second impeller 4, the first air channel 5 is by the first impeller 3 and the curved portions relative with the first impeller 3
Limiting and formed, the second air channel 6 is limited formed by the second impeller 4 and the curved portions relative with the second impeller 4, the concrete shape in each air channel
Shape refers to Fig. 1.
Preferably, as in figure 2 it is shown, be positioned in housing between the first air channel 5 and the second air channel 6 and be additionally provided with for will be by the second leaf
The air-flow that wheel 4 rotates and produces guides the guide plate 7 in the first air channel 5, so that the wind in the second air channel 6 is more easy to pour in the first wind
In road 5.Further, in two curved portions in the present embodiment distance in the heart less than the first impeller 3 and the second impeller 4
In distance in the heart.The purpose so arranged is to make air output in the air outlet in the first air channel 5 and the second air channel 6 bigger
Side is mutually close, makes the second air channel 6 can provide the air-flow of abundance to the first air channel 5, it is ensured that the air output in the first wind district meets
The radiating requirements of electronic equipment, provides installation space for guide plate 7 simultaneously.
When being embodied as, the first impeller 3 and velocity of rotation of the second impeller 4 can be regulated as required, control wind with this
The size of the air output of fan.It addition, the first impeller 3 and the rotation of the second impeller 4 can synchronize also can be asynchronous, such as when the first impeller
After 3 rotate clockwise 1/4 circle, the second impeller 4 starts to rotate counterclockwise.
Present invention simultaneously provides a kind of notebook computer, including system end and display end, system end is internally provided with above-mentioned
Fan.
Above example is only the exemplary embodiment of the present invention, is not used in the restriction present invention, protection scope of the present invention
It is defined by the claims.The present invention can be made respectively in the essence of the present invention and protection domain by those skilled in the art
Planting amendment or equivalent, this amendment or equivalent also should be regarded as being within the scope of the present invention.
