Specific embodiment
Below presently preferred embodiments of the present invention is described in detail so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly defining so as to make to protection scope of the present invention.
Referring to the air quantity analog imaging shown in accompanying drawing 1, described between radiator fan of the prior art, radiating fin
Figure, operationally, fluid is not perpendicular to fan outlet and flows out radiator fan, but becoming larger with flow velocity,
Fluid is subject to the pulling motion that the draw of impeller is produced, and fluid finally to flow with respect to the relative motion of impeller in fan
The absolute movement of body is presented varied angle and inclines from air outlet flows out.According to the direction of air outlet air flow, design fin direction
It is parallel with air-flow direction, according to air quantity of fan air outlet distributing position, specifically to change the angle of inclination of fin, from
And effectively reduce the stop of the air flow of fin.As each air quantity of fan is different, describe relatively difficult with air quantity,
Therefore the angle of fin can be changed according to the velocity flow profile of air outlet.
One embodiment of the inclined notebook computer of radiator air outlet varied angle of the invention, which includes radiating
Fan, the air outlet being arranged on the wind path of radiator fan, a plurality of radiating fins being arranged in air outlet, radiating fin with
The angle that the normal of air outlet plane is in gradually increases along radiator fan rotation direction, i.e. radiating fin and air outlet plane
The angle entirety that normal is in starts angle from 0 ° with air-out direction and gradually increases, and designs a model as ideal, due to
Angle design by the radiating fin of optional position is parallel with the wind direction for changing position, can make to improve wind under present same rotational speed
Amount, reaches more excellent heat dispersion.
As shown in Figure 4, it is in big flow velocity according to the inclined notebook computer of radiator air outlet varied angle of the invention
Under air outlet angle of inclination facilities.Radiating fin is according to the angle for being in the normal of air outlet plane along radiator fan
Rotation direction is divided into first area and second area, wherein, the radiating fin of radiating fin, second area in first area
Piece is in each identical angle with the normal of air outlet plane, the normal institute of the radiating fin in first area and air outlet plane
The angle that the angle for being in less than the radiating fin of second area with the normal of air outlet plane is in.Radiating fin in first area
The normal of piece and air outlet plane is arrived in 4 ° with the normal of air outlet plane in 0 ° of angle, the radiating fin in second area
45 ° of angle, is set to 10 ° in this example.
As shown in Figure 2, it is in little flow velocity according to the inclined notebook computer of radiator air outlet varied angle of the invention
Under air outlet angle of inclination facilities.Three areas can be divided into according to air outlet angle according to the air outlet position in Fig. 1
Domain, from figure, a dextrad left side is followed successively by：Main air outlet, centre air vent and throat's air outlet.Thus, radiating fin according to air-out
The angle that the normal of mouthful plane is in along radiator fan rotation direction it is same be divided into first area, second area, the 3rd
Region, wherein, the radiating fin of radiating fin, second area, the 3rd region in first area each with air outlet plane
In identical angle, the angle that the normal of the radiating fin in first area and air outlet plane is in is less than second area to normal
Radiating fin and air outlet plane the normal angle that is in, the normal of the radiating fin in second area and air outlet plane
The angle that the angle for being in less than the radiating fin in the 3rd region with the normal of air outlet plane is in.
According to seeing on air quantity simulation drawing, what main wind outlet wind was almost vertically gone out, so the radiating fin in first area
Piece is minimum with the angle of the normal of air outlet plane, it is proposed that at 0 °；Angle at middle air port between air-flow and air outlet starts
Increase, so air outlet angle of inclination also gradually should increase, it is proposed that the radiating fin in second area and air outlet plane
In 5 ° to 25 ° of angle, preferably 10 ° is 5 ° to 25 °, in this example to normal；Folder at throat air port between air-flow and air outlet
Angle is maximum, so air outlet angle of inclination is maximum, it is proposed that the radiating fin in the 3rd region and air outlet plane
In 4 ° to 45 ° of angle, preferably 25 ° is 10 ° to 45 °, in this example to normal.
As shown in Figure 3, it is in big flow velocity according to the inclined notebook computer of radiator air outlet varied angle of the invention
Under air outlet angle of inclination facilities, first area in the program, second area, the radiating fin in the 3rd region are successively
0 °, 25 °, 45 ° is set to, the radiating fin angle of inclination of the same area is identical, overall gradually to increase with air-out direction angle.
Angle design more than comprehensive in several embodiments, and comprehensive other schemes, represent below in table form
The actual contrast test result of air quantity, blast.
Can be seen that with reference to the accompanying drawing 5 that P-Q curve charts are made according to table 1：In the case of radiating fin, the air quantity of fan,
Blast is maximum；Relatively without radiating fin situation, when there is fin, the air quantity of fan, blast have decline；Relatively fin inclination angle is 0
When spending, when inclination angle is not 0 degree, air quantity rises more than 14%, blast rises more than 7%, and 0 ° -25 ° of design effect
Preferably.As a result of above technical scheme, change fin and design with fan outlet angle of inclination, subtract can fluid impedance
It is little, flow relative increase, so as to improve the performance of whole radiating.
In another embodiment of the present invention, also including angle of fins adjustment unit and control unit, control unit reality
When monitor the operational factor of notebook computer and control angle of fins adjustment unit and change and the normal angle of air outlet plane
Size, operating above parameter includes the rotating speed of CPU usage, display card opening or radiator fan.
For example, increase an air outlet flow rate detection device and detect air outlet flow velocity, according to different flow velocity adjustment fins
Heeling condition；When wind speed is 1m/s ~ 4m/s, it is set to air outlet under little flow velocity and arranges.When wind speed is 4m/s ~ 10m/s, arrange
Arrange for the air outlet under big flow velocity.
And for example, calculate CPU and use percentage ratio, when CPU uses percentage rate below 40%, fin is set to into little flow velocity
Lower air outlet is arranged；When CPU is more than 40% using percentage rate, fin is set to into air outlet under big flow velocity and is arranged.
For another example, detect whether display card is opened, when display card is not opened, fin is set to into air-out under little flow velocity
Mouth is arranged；When display card is opened, fin is set to into air outlet under big flow velocity and is arranged.
Embodiment of above technology design only to illustrate the invention and feature, its object is to allow and are familiar with technique
People understands present disclosure and is carried out, and can not be limited the scope of the invention with this, all according to spirit of the invention
The equivalence changes or modification done by essence are encompassed by protection scope of the present invention.
