Description
Technical field
This utility model is relevant with radiator fan, a kind of radiator fan for electronic installation.
Background technology
Consumption in recent years electronic installation becomes increasingly popular, development based on science and technology, and the volume of electronic building brick gradually reduces, but its
Performed application program but tends to complicated, and therefore electronic building brick can produce substantial amounts of heat energy at work, so needing in heat radiation
Ask also with greater need for attention, if can not effectively dispel the heat, work efficiency will be had a strong impact on.The mode of heat radiation mainly has two kinds: one
Planting is the passive component utilizing radiating fin or heat radiation conduit etc, by increasing the contact area between thermal source to derive heat
Can, but, this passive radiating mode can not meet the radiating requirements of present consumer electronic device.
Another kind of then be structure as shown in Figure 1, utilize fan motor to produce air-flow and walk heat energy with main belt, be more effective
Radiating mode.Also, due to DC Brushless Motor, to have the curve approximation of rotating speed and torque linear, and life-span length, no
Mechanical nose can be produced, electro instrument noise will not be produced, do not have that wave interference, rotating torsion are big, easily manufacture multi-electrode type horse
Reach and manufacture that torsion is stable, stabilization of speed, the advantages such as round and smooth and stable torque can be obtained, and having in running up and high
The function of precision controlling, is therefore widely used on various radiator fan product.LGA 775 frame is being released at Intel in 2004
While structure, PWM unit (PWM--Pulse Width Modulation) control system is added fan horse the most simultaneously
Reach in framework, make fan motor adjust rotating speed at any time according to the temperature of CPU so that it is to reach preferably usefulness.
But, owing to the operating usefulness of DC Brushless Motor has inseparable relation with the number of the magnetic pole that magnetizes, because of
For it with square wave analog sine, so the number of the magnetic pole that magnetizes is the most, then rotor operating is the most smooth and easy, and DC Brushless Motor
Running efficiency and rotating speed all can improve relatively, and the electric current needed for starting operating is relatively low, but for existing technology,
Small-sized DC Brushless Motor, because narrow space, particularly relates to the small-sized heat radiating fan applied in the middle of electronic equipment, causes
The excitatory yoke sheet quantity manufacture of stator pack cannot coordinate the permanent magnet of rotor magnetize number of magnetic poles synchronize improve, for direct current without
The enhancement of brush motor running usefulness forms obstruction greatly.
Along with development in science and technology is growing, under the effort of related researcher is researched and developed, the number of poles of DC Brushless Motor is also
Having promoted, the most the product of the ends of the earth or 12 poles or the above magnetic pole that magnetizes comes out, but, the most common fan motor
The highest driving only supported to six types of severe debility disease motor of the logic control of driver element designs, and does not have the height more than for the ends of the earth or the ends of the earth
The number of magnetic poles motor design driven that magnetizes controls, if causing electronic installation to select the height of more than the ends of the earth or the ends of the earth to magnetize number of magnetic poles fan
Motor, this fan motor driver element still calculates basis with six types of severe debility disease as rotating speed, thus makes actual speed and the reason of fan motor
Opinion operating value rotating speed is not inconsistent.
For example, when select six types of severe debility disease magnetize magnetic pole fan motor time, its fan motor driver element magnetizes magnetic with six types of severe debility disease
Pole is as calculating basis, and this fan motor driver element calculates often through the change of six magnetic poles that magnetize, this fan motor
Driver element is i.e. calculated as rotor rotation and turns around, and the rest may be inferred, so when the rotating speed of fan motor is such as 4,000 (rpm), its
Can be magnetized pole change through 4,000 (rpm) * 6 pole=24,000 time；But, the magnetic pole fan motor if magnetizing in the selection ends of the earth
Time, due to do not aim at the ends of the earth magnetize pole design fan motor drive unit drives control, therefore this fan motor drive
Unit still magnetizes magnetic pole as rotating speed calculating basis with six types of severe debility disease；That is, this fan motor driver element calculates and is still often to pass through
One six pole change that magnetize, this fan motor driver element is i.e. calculated as rotor rotation and turns around；So, magnetize magnetic when the ends of the earth
Pole fan motor, often through six pole change that magnetize, is i.e. calculated as rotor rotation and turns around that (that is real-world operation is only four
/ tri-circles), cause fan motor rotating speed too low, thus cannot effectively get rid of the thermal source in electronic installation, and then affect electronics
The task performance of device.
In view of this, how to improve the problems referred to above and be the primary problem that this utility model to be solved.
