Description
[technical field]
The present invention is about a kind of radiator, a kind of radiator with centrifugal fan and tube-axial fan.
[background technology]
Along with the most scientific and technological development, in computer system or other electronic systems, the arithmetic speed of processing means is more come
The fastest, and required data quantity to be processed also gets more and more, therefore processing means produced temperature during process data
Spend more and more higher, so the problem of heat radiation is the most aobvious with technology important.
In order to solve the problem of heat radiation, at present many by arranging radiator on arithmetic unit or heat radiation module processes and dissipates
The work of heat, and current modal radiator or heat radiation module are mainly with the master that is designed as of fan, such as in centre
Fan assembly is all had to dispel the heat on reason device or display wafer.
At present in the fansink designs of single fan, when running often along with the rising of temperature, and must relatively promote
Rotation speed of the fan, but the rotating speed of fan itself must have it to limit, and cannot unconfined promote always.And, improving fan
While rotating speed, make also fan when rotating produced noise increase therewith, add fooled rotation speed of the fan the highest time, fan meeting
Enough air cannot be sucked, cause the air pressure within fan relatively low, and then affect the air output of fan.
Furthermore, when being in high-speed state due to fan, its air output cannot effectively promote, and therefore fan needs into one
Step increase rotating speed is to increase air output, but now cannot may improve rotation speed of the fan again, or may be such that noise content one
And promote.
How to overcome current existing fan because its rotating speed has limited cannot heat radiation usefulness, and how gram this
Take known techniques and cannot take into account the situation of high heat dissipation efficiency and low noise value, be that presently relevant person skilled in the art is urgently to be resolved hurrily
Problem.
[summary of the invention]
In order to solve the disappearance of above-mentioned known techniques, the present invention provides a kind of radiator, uses solution and commonly uses single fan
Radiator cause air output not enough because rotation speed of the fan limits, and promoting the high noisy caused while rotation speed of the fan
Problem.
The radiator of the present invention includes a fin unit, a centrifugal fan and a tube-axial fan.Centrifugal fan
It is arranged at the side of fin unit, rotates with one first axle center, and there is an air intake direction and an air-out direction, enter
Paralleling with the first axle center in wind direction, air-out direction and the first axle center are perpendicular.Tube-axial fan is obliquely installed in fin unit
Relative opposite side, rotate with one second axle center, there is between the second axle center and the first axle center an angle, and axial-flow type wind
Fan has an air intake direction and an air-out direction, all parallels with the second axle center.The air-flow that centrifugal fan is blown out along from
The air-out direction of core type fan blows to tube-axial fan.
Radiator disclosed by the invention described above, wherein tube-axial fan the air-out of air-out direction and centrifugal fan
Direction intersection, tube-axial fan is selectively driven, and tube-axial fan is from the outer inspiration air-flow of radiator, and discharges air-flow to lead
The dynamic air-flow from the air-out direction of centrifugal fan is discharged outside radiator.
Radiator disclosed by the invention described above, wherein tube-axial fan air intake direction more with the going out of centrifugal fan
The intersection of wind direction, tube-axial fan is selectively driven, and tube-axial fan is from the air-out direction inspiration air-flow of centrifugal fan
And discharge outside radiator.
Radiator disclosed by the invention described above, radiator has further included a housing, wherein fin unit, centrifugal fan
And tube-axial fan is arranged in housing, housing has an opening corresponding to centrifugal fan and tube-axial fan.
Radiator disclosed by the invention described above, the relative opposite side of fin unit is obliquely installed, and tube-axial fan is arranged
Thereon, make, between the second axle center of tube-axial fan and the first axle center, there is angle.
Radiator disclosed by the invention described above, has further included a heat pipe, is arranged at fin unit, wherein heat pipe between from
Between core type fan and tube-axial fan.
The radiator of the present invention, under general operation situation, utilizes centrifugal fan to be inhaled by the cold air outside radiator
Enter, and after its air-flow discharged flows through fin unit, can the torrid zone on fin unit be gone out outside radiator, to reach the effect of heat radiation
Really.And when the temperature of fin unit promotes, tube-axial fan, by the startup of selectivity, now tilts because of tube-axial fan
Design so that tube-axial fan, during air intake and air-out, can draw the air-flow that centrifugal fan discharged and flow through fin
The radiating airflow of unit, the therefore flow efficiency of heat radiation air-flow, reach the purpose of improving radiating effect.
The radiator of the present invention utilizes the operation principles that two kinds of fans are different, by two distinct types of fan collocation fortune
Make, by the efficiency of lifting air current flow, not only can be not required to again rotation speed of the fan is substantially improved with improving radiating effect, can subtract
Few noise, more can take out of the dust in fin unit by the change of air current flow and have effect of dedusting.
Feature for the present invention, implementation and effect, hereby coordinate graphic most preferred embodiment of making to describe in detail as follows.
