Abstract
An ion generator to generate ion flow to ventilate heat comprises an emitter, a receiver and a power supply. The emitter comprises a needle electrode having one needle shaped tip configured as a discharging portion. The receiver comprises a plurality of flow channels for airflow and at least one receiving portion. The at least one receiving portion comprises a line edge arranged around a concave spherical surface, and the discharging portion is at a substantial center of the concave spherical surface. The power supply provides a voltage potential difference between the discharging portion of the emitter and the receiving portions of the receiver.
