Ionic wind generator

A printed circuit board (PCB) mounted ionic air mover comprising:

• a) an ionic air mover assembly for mounting over a PCB opening on a PCB, the assembly having:
• i) a first side and a second side,
• ii) an assembly opening characterized as having a length, a width, and a height, the assembly opening traversing from the first side to the second side of the ionic air mover assembly, the assembly opening sized to allow air to pass through the assembly opening from the first side to the second side;
• b) an emitter mounted on the first side of the assembly, the emitter positioned across the assembly opening on the first side;
• c) a collector mounted on the second side of the assembly, the collector positioned across the assembly opening on the second side of the assembly;
• and,
• d) a PCB attachment member affixed to at least one of the first side and the second side of the assembly, the PCB attachment member configured to mount the ionic air mover over the PCB opening on the PCB,
• wherein the emitter and the collector are oriented and positioned such that when the ionic air mover is mounted over the PCB opening on the PCB, the emitter and the collector are on opposite sides of the PCB, and when a sufficient differential voltage is applied to the emitter and the collector, air is ionized to produce an airflow through the assembly opening from the first side to the second side, and
• wherein the airflow is capable of passing through the PCB opening on the PCB.
