PCT No. PCT/SE88/00365 Sec. 371 Date Nov. 15, 1989 Sec. 102(e) Date Nov. 15, 1989 PCT Filed Jul. 1, 1988 PCT Pub. No. WO89/00355 PCT Pub. Date Jan. 12, 1989.An arrangement for transporting air, with the aid of an ion-wind, includes a corona electrode (K) at least one target electrode (M) located at a distance from the corona electrode, and a d.c. voltage source (4) connected between the corona electrode and target electrode. The arrangement includes a housing (1, 5) with an inlet opening (2) in which the corona electrode (K) is disposed centrally, and an air-flow path extending from the inlet opening and containing the target electrode (M). The target electrode is located spaced form and symmetrical with the center line through the inlet opening. The housing is configured so that the air-flow path downstream of the inlet opening (2) and the corona electrode (K) branches outwardly towards the target electrode (M), thereby forcing air entering through the inlelt opening (2) out towards the target electrode (M) and preventing at least the major part of this air-flow from continuing straight forwards along the extension of the center line. |
