The working principle of the ion wind radiator 7 is as follows: First, under the action of the high-voltage transformer 9, the current is converted from a low-voltage current to a voltage of 30KV, and acts on the ion wind radiator 7, and a high-voltage electric field of 30KV is generated between the electrodes on the left and right sides , the electrons begin to move toward the anode, colliding with air molecules to produce cations, which are positively charged and attracted by the adjacent electrodes. Under the action of a strong electric field, the positively charged ions will push the neutral molecules in the air to move by the wire, thus forming the wind for cooling. According to theoretical calculations, this ionic wind radiator can generate a wind speed of up to 2.4 m/s. Since the wind speed is much higher than the speed of an ordinary mechanical fan, it can effectively dissipate heat. And because there is no mechanical structure, it can almost Keep running with zero noise.
