What is the principle of a vaneless fan?
The base will be a large amount of air from the suction hole at the bottom of the 5.28 gallons per second flow inhalation, then the air is pressurized into the annular inner wall, an impeller inside the edge of the ring in the air circular trajectory jet, change the air flow will cause the air pressure, and ultimately the formation of a cold air flow shares uninterrupted
The base there is a similar air compressor device, the air is sucked in, after compressed by spraying out annular gap above the ejected air annular air flow driven device, has the wind.
No leaf fan operation, the motor base in the first air inhaled from many hole edge, then the air pushed upward into the hollow pipe ring, the pipe on the side of the thick, with a ring of narrow slit, the air ejected from the slot; at the Bainuliding law, these the air flow will produce a lower pressure in the middle ring, thus driving the rear ring, on the surrounding air flows toward the front of the ring together, blowing.
