First Claim
Patent Images
1. An ion wind fan having a longitudinal axis, a first end, and a second end longitudinally opposite the first end, the ion wind fan comprising:
- a first wire emitter electrode held in tension between the first end and the second end, the first wire emitter electrode being oriented in the direction of the longitudinal axis;
a collector electrode having an upstream side and a downstream side, the collector electrode comprising a first row of openings connecting the upstream and downstream sides, the first row of openings being oriented along the direction of the longitudinal axis, the openings in the first row of openings having an elongated oval shape having a straight portion and a rounded portion; and
an isolator, wherein the first wire emitter electrode and the collector electrode are attached to the isolator so that the first row of openings is substantially centered above the first wire emitter electrode.
