When this gas flow generator 10 works, by in the coil 1312 of the first moveable magnet 131 of the first actuator 13 to these gas current generating unit 12 and pass in periodically variable electric current respectively in the coil 1412 of the second moveable magnet 141 of the second actuator 14, to magnetize the iron core 1411 of the iron core 1311 of the first moveable magnet 131 of the first actuator 13 and the second moveable magnet 141 of the second actuator 14 respectively.The iron core 1311 of described first moveable magnet 131 and the iron core 1411 of the second moveable magnet 141 after magnetization respectively and the first fixed magnet 132 of the first actuator 13 and the second actuator 14 the second fixed magnet 142 between produce and attract or repulsive interaction comparatively by force, to drive this first vibrating diaphragm 121 and the second vibrating diaphragm 122 move toward one another or move dorsad simultaneously, repeatedly the gas compression in the first chamber 124 of casing 120 is pushed in the runner 1231 of nozzle 123, thus periodically produce an air-flow at the outer end place of nozzle 123 and spray to radiator 20.This air-flow flow forward to carry out heat exchange with fin 21 in the gas channel 22 entering radiator 20, thus the heat reaching fin 21 is taken away.
Refer to Fig. 5 to Fig. 7, illustrate the production process of air-flow below with a period of motion of single gas current generating unit 12.
The production process of air-flow is divided into three phases.As shown in Figure 5, in the first stage, in the coil 1312 of the first moveable magnet 131, pass into sense of current is forward (or negative sense), after the iron core 1311 of the first moveable magnet 131 is magnetized, the polarity at the two ends that iron core 1311 is close to each other with the first fixed magnet 132 is identical, namely the polarity of iron core 1311 near one end of the first fixed magnet 132 is identical with the polarity of the first fixed magnet 132 near one end of iron core 1311, and the first moveable magnet 131 and the first fixed magnet 132 are repelled mutually.Because the first fixed magnet 132 is fixed on casing 120, the first moveable magnet 131 is moved away from the first fixed magnet 132 under the effect of repulsive force, thus drive the first vibrating diaphragm 121 to move towards the second vibrating diaphragm 122 by the first moveable magnet 131.Meanwhile, in the coil 1412 of the second moveable magnet 141, pass into sense of current is forward (or negative sense), after the iron core 1411 of the second moveable magnet 141 is magnetized, the polarity at the two ends that iron core 1411 is close to each other with the second fixed magnet 142 is identical, namely the polarity of iron core 1411 near one end of the second fixed magnet 142 is identical with the polarity of the second fixed magnet 142 near one end of iron core 1411, and the second moveable magnet 141 and the second fixed magnet 142 are repelled mutually.Because the second fixed magnet 142 is fixed on casing 120, the second moveable magnet 141 is moved away from the second fixed magnet 142 under the effect of repulsive force, thus drive the second vibrating diaphragm 122 to move towards the first vibrating diaphragm 121 by the second moveable magnet 141.That is, under the effect of the first actuator 13 and the second actuator 14, the first vibrating diaphragm 121 and the second vibrating diaphragm 122 move toward one another simultaneously, thus common compression the first chamber 124.
As shown in Figure 5, this first vibrating diaphragm 121 and the second vibrating diaphragm 122 move in the process of position shown in dotted line 121a, 122a in figure by original horizontal position respectively, gas in first chamber 124 is moved in the runner 1231 of nozzle 123 by compressing, thus nozzle 123 one first air-flow 31 going out interruption-forming tool fair speed and blow to radiator 20, this first air-flow 31 travels forward along the gas channel 22 between fin 21 and carries out heat exchange to be taken away by the heat reaching fin 21 with fin 21.
In second stage, sense of current is passed into reverse in the coil 1312 of the first moveable magnet 131, after the iron core 1311 of the first moveable magnet 131 is magnetized, the polarity at the two ends that iron core 1311 is close to each other with the first fixed magnet 132 is contrary, namely the polarity of iron core 1311 near one end of the first fixed magnet 132 is contrary with the polarity of the first fixed magnet 132 near one end of iron core 1311, and the first moveable magnet 131 and the first fixed magnet 132 are attracted each other.Because the first fixed magnet 132 is fixed on casing 120, the first moveable magnet 131 is moved under the effect of suction towards the first fixed magnet 132, thus by the first moveable magnet 131 drive the first vibrating diaphragm 121 dorsad the second vibrating diaphragm 122 move.Meanwhile, sense of current is passed into also reverse in the coil 1412 of the second moveable magnet 141, after the iron core 1411 of the second moveable magnet 141 is magnetized, the polarity at the two ends that iron core 1411 is close to each other with the second fixed magnet 142 is contrary, namely the polarity of iron core 1411 near one end of the second fixed magnet 142 is contrary with the polarity of the second fixed magnet 142 near one end of iron core 1411, and the second moveable magnet 141 and the second fixed magnet 142 are attracted each other.Because the second fixed magnet 142 is fixed on casing 120, the second moveable magnet 141 is moved under the effect of suction towards the second fixed magnet 142, thus by the second moveable magnet 141 drive the second vibrating diaphragm 122 dorsad the first vibrating diaphragm 121 move.That is, under the effect of the first actuator 13 and the second actuator 14, the first vibrating diaphragm 121 and the second vibrating diaphragm 122 move simultaneously dorsad.
When position shown in dotted line 121a, 122a during the first vibrating diaphragm 121 and the second vibrating diaphragm 122 are by Fig. 5 is moved in the process being back to horizontal level shown in Fig. 6, the first air-flow 31 entered in the gas channel 22 of radiator 20 moves forward, simultaneously the air of nozzle 123 periphery be sucked into radiator 20 gas channel 22 in form one second air-flow 32, the flow of this second air-flow 32 can up to ten times of the first air-flow 31.
