Abstract

A heat dissipation apparatus includes an insulating plate, a conductive plate located on the insulating plate and a power source with an anode connected with the insulating plate and a cathode connected with the conductive plate. A conductive element is received in the insulating plate and is connected to the anode of the power source. When the heat dissipation apparatus is activated, the conductive element ionizes air closing to the insulating plate to produce positive ions. The conductive plate attracts the positive ions to move fast towards the conductive plate, which cause the air to flow in a direction in which the positive ions move.

Claims (27)

1. A heat dissipation apparatus for dissipating heat by movement of air, comprising:

a perforated non-conductive insulating plate;

a perforated conductive plate; and

a conductive element,

wherein, the conductive element is positioned upon the non-conductive insulating plate;
