1. An electrostatic air-cooled heat sink comprising:
a frame, made of solid insulating materials to form a hollow framework, comprising of a first opening, a second opening, and a holding space located between the first and second openings; a power controller, assembled onto the frame for controlling the power supply state; a sharp electrode (corona electrode), made of conducting materials and integrally located at the first opening of the frame; said sharp electrode is provided with at least a sharp electrode portion, which is folded and protruded towards the holding space; a first power feed portion is set on the sharp electrode and electrically connected with the power controller; at least a through-hole, formed correspondingly to the sharp electrode portions of the sharp electrode; and ribs are formed at periphery of said through-hole; a guide frame, assembled into the holding space of the frame; made of conducting materials, the guide frame is provided with guide plates arranged at interval; a guide channel is formed between the guide plates, and both ends of the guide channels are oriented separately towards the first and second openings; one end of the guide channel facing the first opening is located opposite to the sharp electrode portion of the sharp electrode; insulating configuration between the guide frame and sharp electrode is required; a second power feed portion is set onto the guide frame and electrically connected with the power controller; a half-bowl blunt electrode assembly, set onto the guide plate of the guide frame in a manner that at least a half-bowl blunt electrode unit is integrally formed at one end of the guide plate facing the first opening, and the other half-bowl blunt electrode unit is formed correspondingly to the guide plate; so said half-bowl blunt electrode assembly comprise of these two half-bowl blunt electrode units set at interval; a flow-through portion, formed by a space set between two half-bowl blunt electrode units; and said flow-through portion must be connected with the guide channel between the guide plates as well as the through-hole formed by the sharp electrode; of which, the end of the sharp electrode portion formed by the sharp electrode is located correspondingly to the center of the half-bowl blunt electrode assembly, and a spacing is kept between two half-bowl blunt electrode units. |
