Abstract

The invention discloses an ion fan with a self-cleaning function, which comprises a collecting electrode, a discharge electrode for heat dissipation, a discharge electrode for self-cleaning and an electrode frame. The collecting electrode comprises a substrate that is in contact with a heating element, and fins arranged at equal intervals on the substrate, wherein an ion wind channel is formed between the fins. The discharge electrode for heat dissipation is fixed to the electrode frame above the ion wind channel, and the discharge electrode for self-cleaning is located on the electrode framelocated on one side of the ion wind channel. The collecting electrode, the discharge electrode for heat dissipation and the discharge electrode for self-cleaning are connected with a power supply viawires, and the discharge electrode for heat dissipation and the discharge electrode for self-cleaning are controlled independently by switches. The ion fan is simple in the system structure, free of vibration noise, low in energy consumption and capable of better exerting the inherent advantages of the ion fan.

Description

technical field [0001] The invention relates to the field of heat dissipation, in particular to an ion fan with self-cleaning function. Background technique [0002] Ionic fans have the advantages of small size, no noise and vibration, and easy adjustment of shape, and have been more and more researched in the field of heat dissipation. However, during the operation of the ion fan, dust in the air will accumulate on the collector and discharge electrodes, and the dust accumulation will reduce the heat dissipation performance of the ion fan. Therefore, it is extremely important to remove the dust on the ion fan in time. [0003] The U.S. Patent No. 4318718 discloses an ion fan that uses a nozzle to remove dust, and the nozzle ejects high-speed flowing gas to remove dust on the discharge electrode. The U.S. Patent No. 6868242 discloses a mechanical dedusting method in which the discharge electrode of the ion fan stretches into the aperture of the band cleaning pad, and remov...
