され、また負コロナ放電極５は接地11されている。In FIG. 1, reference numeral 1 denotes a blower casing, which is formed of an insulating material or the like in a cylindrical shape. Inside the blower casing 1, collector electrodes 2 and 3 and positive and negative corona discharge electrodes 4 and 5 are arranged in multiple stages from the outlet 1a on the downstream side to the upstream side. That is, from the outlet 1a, is arranged a collector electrode 2 of the ground 6 is wire mesh, positive corona charging electrode 4 composed of a plurality of needle electrodes 7 and a predetermined distance d 1 apart upstream
Is arranged, and the collector electrode 3 made of a wire mesh is arranged on the upstream side, and the negative corona discharge electrode 5 composed of a plurality of needle electrodes 8 is arranged on the upstream side at a predetermined distance d 2 . A positive DC high power source 10 whose one end is grounded 9 is connected to the positive corona discharge electrode 4 and the collector electrode 3 on the upstream side thereof, and the negative corona discharge electrode 5 is grounded 11.

れ単独に印加するよりも少ない入力電力で風速及び風量
を増加できる。In the above, negative corona is generated between the negative corona discharge electrode 5 on the upstream side of the blower casing 1 and the collector electrode 3 on the downstream side thereof, and a positive corona is generated between the positive corona discharge electrode 4 and the collector electrode 2 on the downstream side thereof. Ion wind is generated at the same time as shown by the arrow in the figure. At this time, positive and negative coronas are generated in the blower casing 1, so that ozone generation can be reduced. In addition, since the corona discharge electrode is multi-staged and the positive DC high power source 10 is simultaneously applied to the positive corona discharge electrode 4 and the collector electrode 3 on the upstream side of the positive corona discharge electrode 4, it requires less input power than individually applied. The wind speed and volume can be increased.

が判る。FIG. 4 shows the relationship between the wind speed and the input power when the positive and negative corona discharge electrodes are individually driven, and the relationship between the wind speed and the input power when the positive and negative corona discharge electrodes are driven simultaneously as in the present invention. As can be seen from the figure, when the positive and negative corona discharge electrodes are individually driven, the wind speeds with respect to the input power are substantially the same as shown by the curves a and b, but the present invention is shown by the curve c. In the case of, the wind speed increases (about twice) even when the input power is the same as when driven alone.
また印加電圧は10〜20kVであるが正負のコロナ放電で
はブレークダウン電圧が異なるため、上述した電極間距
離d1,d2を調節して両者のブレークダウン電圧を一致さ
せる。The applied voltage is 10 to 20 kV, but the breakdown voltage is different in positive and negative corona discharges. Therefore, the above-mentioned inter-electrode distances d 1 and d 2 are adjusted to make the breakdown voltages match.
第２図は本発明の他の実施例を示す。 FIG. 2 shows another embodiment of the present invention.
第２図においては各電極の配置は第１図と略同じであ

となる。In FIG. 2, the arrangement of each electrode is almost the same as that in FIG. 1, but the applied voltage is a negative DC high power source 12.
Therefore, the discharge electrode on the side of the outlet 1a becomes the negative corona discharge electrode 5, and the discharge electrode on the upstream side 11 which is grounded 11 is the positive corona discharge electrode 4.
Becomes

のため、オゾンの発生をさらに低減できる。In this example, since there are multiple stages, the wind speed and air volume are further improved. Further, since the positive corona discharge electrode 4 has two stages and the negative corona discharge electrode 5 has one stage, the generation of ozone can be further reduced.

Further, since the diameter and cross-sectional shape of the blower casing 1 can be freely set, the blower casing 1 can also be used as a blower for cooling various electronic components mounted on an electronic board.
