Abstract
A rectifying device is prepared as setting said rectifying device to be form of flat channel being set between centrifugal fan and heat radiation fin-plate, forming said rectifying device by multiple flow guide plate to form multiple runner for improving uniformity of airflow speed entering into heat radiator fin-plate and furthermore improving heat radiation efficiency of heat radiation fin-plate.
Description
Technical field
The present invention relates to a kind of heat abstractor of high heat-flux thermal source, particularly a kind of centrifugal fan that is used for computer is with the rectifying device of the heat dissipation of the radiating fin that improves computer.
Background technology
Heat abstractor in the notebook, because be subjected to the restriction of space and weight, usually utilize heat delivered that one group of heat pipe produces computer chip to long-range radiating fin, relend the forced convertion that helps fan and the cold air in the external world is sucked and blow over radiating fin, and heat is shed to the computer fuselage.The form of fan comprises centrifugal fan and tube-axial fan.Centrifugal fan is thinner, and adopts the side-blown mode, so be usually used in the radiating module of mobile computer.Known technology as shown in Figure 1, air-flow directly blows to radiating fin 3 from the air outlet 2 of centrifugal fan 1.But in this configuration, the wind speed of centrifugal fan air outlet 2 positions is also inhomogeneous, the wind speed in its outside is much larger than inboard wind speed, when air-flow when centrifugal fan air outlet 2 directly blows to radiating fin 3, the wind speed that radiating fin 3 is received is also inhomogeneous, is not enough to bring into play the maximum heat dissipation of radiating fin.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of rectifying device that is used for centrifugal fan, enters the uniformity of the air velocity of radiating fin with improvement, thereby brings into play the maximum heat dissipation of radiating fin.
For solving the problems of the technologies described above, the technical solution used in the present invention is, the rectifying device that is provided, place between centrifugal fan and radiating fin, two ends are respectively air inlet and air outlet, be a flat passage between air inlet and the air outlet, the flat channel interior has a plurality of bafflers that are connected in conduit wall, and flat channel interior separated by spaces is become a plurality of runners.
Compared with prior art, the present invention is owing to adopt baffler that the gas channel inner space is separated into a plurality of runners, can control the uniformity of exit air-flow, the present invention is placed between centrifugal fan and the radiating fin, the uniformity of the air velocity that enters radiating fin can be improved, thereby the heat dissipation of radiating fin can be brought into play better.
Description of drawings
Fig. 1 is the assembling mode of centrifugal fan and radiating fin in the prior art;
Fig. 2 places a kind of embodiment between centrifugal fan and radiating fin with the present invention;
Fig. 3 is the embodiment that baffler is made up of a plurality of discontinuous segments among the present invention;
Fig. 4 is the embodiment that increases ledge among the present invention on the baffler;
Fig. 5 is integrated in another embodiment in the fan with the present invention.
Embodiment
The present invention is further detailed explanation below in conjunction with accompanying drawing.
Among Fig. 2, with a kind of rectifying device 4 provided by the invention, place between centrifugal fan 1 and the radiating fin 3, its two ends are respectively air inlet 7 and air outlet 8, be a flat passage between air inlet 7 and the air outlet 8, the flat channel interior comprises a plurality of bafflers 5, forms a plurality of runners 6, enter the uniformity of the air velocity of radiating fin 3 with improvement, and then bring into play the maximum heat dissipation of radiating fin 3.The entrance section of each runner is long-pending can to differ from one another, and is principle can improve airflow homogeneity, and the cross section of each runner can be made becomes flaring, parallel or convergent form.With Fig. 2 is example, and several runners of top are bigger near this place because of the fan outlet air-flow, so adopt the flaring form; Several runners of mid portion are placed in the middle at this place because of the fan outlet air-flow, so adopt parallel form; The runner of below is minimum near this place because of the fan outlet air-flow, so employing convergent form.The outlet total sectional area of the flat passage of this rectifying device 4 can be greater than the inlet total sectional area, to increase the coverage area of exit flow.The runner of flaring can cause the flow field to be separated and whirlpool, can strengthen heat radiation.
Can comprise a plurality of holes on each baffler 5, or form, make 6 of each runners be able to intercommunication, make pressure distribution each other more even, as shown in Figure 3 by a plurality of discontinuous segments.Also can comprise on the baffler 5 and staggered strip or the columnar protrusions part of airflow direction,, strengthen heat radiation, as shown in Figure 4 to increase turbulent flow.On baffler, increase jut to strengthen the mode of turbulent flow, be particularly suited for parallel and the convergent runner.Fig. 5 represents that baffler 5 can directly be incorporated in the fan.Rectifying device 4 also can be integrated (not shown) with radiating fin 3.
