Abstract
A fan cooling system for use with an electronic apparatus having a fan for providing a cooling draft and adapted to remove draft-borne dust includes: an input module for receiving a control instruction; a programmable logic module electrically connected to the input module and adapted to validate the control instruction received by the input module and output a logic result in accordance with the control instruction; and an electrostatic module comprising an electrostatic filtering unit and an electrostatic controlling unit electrically connected to the electrostatic filtering unit and the programmable logic module, wherein the electrostatic filtering unit adjoins the fan to take the cooling draft, and the electrostatic controlling unit applies static electricity to the electrostatic filtering unit in accordance with the logic result sent from the programmable logic module and thus enables the electrostatic filtering unit to electrostatically adsorb draft-borne dust.
