Description
[technical field]
The present invention relates generally to a kind of heating radiator, espespecially a kind of heating radiator with overlapped fan.
[background technology]
Because the technology such as three-dimensional animation or electronic game is fast-developing now, computer system needs more dynamical display card could process huge data, also therefore makes display card produce huge heat.In order to solve the heat dissipation problem of display card, heat radiation module usually can be installed on display card.
Referring to Fig. 1, is the stereographic map of known display device.Display device 1a comprises a display card 2a and and to dispel the heat module 3a, heat radiation module 3a is arranged on display card 2a, a centrifugal fan 4a is provided with in heat radiation module 3a, utilize centrifugal fan 4a fast rotational to suck air along one first airflow direction D1, rear air is by surrounding's outflow of centrifugal fan 4a, and blow to the radiating fin (not shown) of heat radiation module 3a inside, dispel the heat to help display card 2a.
But the heat produced due to display card 2a is now excessive, therefore needs the rotating speed improving centrifugal fan 4a, just can reach the heat dissipation needed for display card 2a.But after the rotating speed of centrifugal fan 4a improves, the noise that centrifugal fan 4a produces can sharply increase, and can cause noise jamming to user.
[summary of the invention]
When known centrifugal fan rotating speed is very high, centrifugal fan can cannot suck enough air, and the air pressure causing centrifugal fan inside is lower, and then have impact on the air output of centrifugal fan.Also because air output during high rotating speed cannot effectively promote, therefore centrifugal fan needs to increase rotating speed further to increase air output, but this can make noise content promote in the lump.
In order to solve the disappearance of above-mentioned prior art, object of the present invention provides a kind of heating radiator with overlapped fan, it comprises a centrifugal fan and a tubeaxial fan, tubeaxial fan is overlapped in the side of centrifugal fan, the air-flow blown out to make tubeaxial fan blows to centrifugal fan, to increase the air pressure of centrifugal fan inside, make centrifugal fan can improve air output under not improving rotating speed further.Therefore the present invention can operate centrifugal fan and tubeaxial fan with lower rotating speed, and then the noise that reduction integrated radiator produces.
To achieve the above object, the invention provides a kind of heating radiator with overlapped fan, comprise a centrifugal fan, with a tubeaxial fan, also can comprise a shell body further, its inside is provided with an accommodation space.Centrifugal fan is arranged at the accommodation space of shell body inside, and is provided with an inlet side.Tubeaxial fan is articulated in the outside of shell body and the inlet side of centrifugal fan.Wherein tubeaxial fan is optionally driven, and when tubeaxial fan is driven, the air-flow that tubeaxial fan blows out blows to the inlet side of centrifugal fan, and centrifugal fan and tubeaxial fan all rotate along a turning axle.
To achieve the above object, the present invention separately provides a kind of display device, comprise a display card, a centrifugal fan, with a tubeaxial fan.Display card has a heater element, and centrifugal fan has an inlet side, and centrifugal fan is arranged at the side that display card has heater element, and the air-flow that this centrifugal fan produces enters rear guiding display card by inlet side and dispels the heat to the wafer on display card.Tubeaxial fan is arranged at the inlet side of centrifugal fan, and the air-flow that wherein tubeaxial fan blows out blows to the inlet side of centrifugal fan.
In sum, due to centrifugal fan inside air pressure can increase by tubeaxial fan, therefore centrifugal fan compared to prior art, under identical rotating speed, more easily can suck air, and then produces more air output.Therefore tubeaxial fan of the present invention and centrifugal fan can adopt less rotating speed, reach preferably radiating effect, and then effectively reduce the noise that integrated radiator produces, to reduce the noise jamming to user.
