| 摘要 |
The present invention relates to devices and methods for whirling a liquid comprising water, and further to different uses of such a device. The device comprises a vortex unit (10; 20; 40; 50V, 50H; 60; 70V, 70H) comprising seven essentially parallel elongate helical elements (11; 21V, 21H; 41V, 41H; 61), of which six are positioned around the seventh. The device may be used, for instance, for improving the performance of a coolant, for exhaust emission control, and for reducing the effect of electromagnetic radiation in an environment. |
