Abstract
A flow tube apparatus may include a flow tube having a first opening and a second opening, a corona electrode provided in the flow tube, a collecting electrode provided in the flow tube, and at least one focusing electrode provided in the flow tube to guide ions and thereby provide an ionic wind. In at least one embodiment, the flow tube apparatus may be provided in an electronic apparatus to provide an air flow.
Claims24
A flow tube apparatus comprising:
- a flow tube having an opening;
- a corona electrode;
- a collecting electrode, the corona electrode and the collecting electrode to provide a movement of ions in the flow tube;
- and
- a plurality of focusing electrodes to be provided in the flow tube to guide the ions in a direction toward the opening, and a first one of the focusing electrodes to receive a first voltage and a second one of the focusing electrodes to receive a second voltage.
2 more elements
An electronic apparatus comprising:
- an electronic component to generate heat;
- a flow tube apparatus to provide an air flow from a first opening to a second opening;
- and
- a voltage supply to supply power to the electronic component and to the flow tube apparatus,
- wherein the flow tube apparatus includes:
- a flow tube,
- a corona electrode and a collecting electrode to ionize gas molecules in the flow tube, and
- a plurality of focusing electrodes to provide an assist discharge to the ionized gas molecules, and a first one of the focusing electrodes to receive a first voltage from the voltage supply and a second one of the focusing electrodes to receive a second voltage from the voltage supply.
5 more elements
A method comprising:
- providing a corona discharge in a flow tube by applying an electronic field between a corona electrode and a collecting electrode;
- and
- providing an assisted discharge to ionize gas molecules in the flow tube by applying a voltage to at least one focusing electrode.
