Description
Technical field
The present invention relates to a kind of radiator fan, especially one kind to be installed with radial air gap motor, and whole axial height
The radial air gap motor size selection side of the relatively thin thin heat radiation fan and thin heat radiation fan with radial air gap motor
Method.
Background technique
In recent years, as electronic product is lightening and high performance development trend, when electronic product operates, electronic component
Heating temperature improve, the factors such as be limited plus heat-dissipating space, so that electronic component not easy heat radiation, to be easy to produce efficiency not
Stable situation, influences the reliability of electronic product, and functional characteristic is caused to decline, and can not play and even work as machine, therefore radiates
One of the important topic to be considered when having become current design of electronic products.
Wherein, increasing the most-often used mode of radiating efficiency is exactly that radiator fan is installed in electronic product, by heat dissipation
The wind dispelling effect of fan forces air-flow to flow, and the high-temperature gas inside electronic product is discharged, and is suitable for light and thin type electronics
The radiator fan of product, then would generally arrange in pairs or groups the thin heat radiation fan (axis part of its fan frame for selecting whole axial height relatively thin
The axial height of bottom surface to the wheel hub top surface of impeller may be, for example, 2 to 4.5 millimeters or so).However, to the stator of its motor with turn
For thin heat radiation fan between son with radial air gap, when designing the thin heat radiation fan, though it wishes to contract as much as possible
Subtract the axial height of radiator fan with up to " thinning " purpose, if but being limited to feel between stator and rotor that magnetic surface product is too small to be will lead to
Motor efficiency is insufficient, so that the problem of influencing the thin heat radiation fan performance, therefore the thinning of thin heat radiation fan design still needs to examine
The equilibrium relation of amount and fan performance.
On the other hand, during Earlier designs radiator fan, often by the experience of designer or pass through trial and error
The mode of (try and error) carries out fan performance after the two collocation assembling to select the size of motor and fan frame again
Test, until fan performance requirement up to specification；It is, early stage because motor with it is in the selection of fan frame size assortment and irrelevant
Formula can be followed, and increase many exploitation time-histories and labour on foot.It is China's No. 101113737 " wind of bulletin for this purpose, please referring to Fig. 1
The selecting method of fan and its motor dimension " Patent Case, which includes a fan frame 91, an impeller 92 and a motor 93, the leaf
Wheel 92 is placed in the fan frame 91, which has a rotor structure 931 and a stator structure 932, and the stator structure 932
The rotor structure 931 can be driven to rotate, generate air-flow to drive the impeller 92 to rotate；Wherein, the width Y of the fan frame 91 with should
The selection of the diameter X of stator structure 932 is to meet relational expression (Y=13.25X1.4, and the diameter X of the stator structure 932 ± 5%)
Ratio with the width Y of the fan frame 91 is 0.25 to 0.5.In this way, which by the relational expression, designer can be quickly and accurately
The fan frame and motor dimension of collocation are selected, to shorten the time-histories of exploitation fan, and ensures that the fan has good fan performance.
However, above-mentioned relation formula is only applicable to thickness more than or equal to 38 millimeters, and the width Y of fan frame 91 is between 4 to 12
Centimetre fan, the relational expression and can not suitable for fan frame axis part bottom surface to the wheel hub top surface of impeller axial height 2
To 4.5 millimeters or so of thin heat radiation fan.Furthermore one of parameter of the relational expression be fan frame 91 width, but light by
Therefore the width of fan frame 91 and the form that can not directly determine whole fan frame 91 may not necessarily be developed correctly by the relational expression
Provide the fan of superperformance.
