Principle of Micro Cooling Fan

"Micro Cooling Fan" from the people the best control in more than two meters, if the home space is limited in scope, you can select the fan blowing against the wall, then let the wind reflection over. In fact, the air is not compressed, the principle is similar to an airplane wing, above the ring wall thickness is not uniform, that is the side of the ring diameter is relatively large, on the other side relatively small, so that the air blown out from the bottom through the ring, it will weaken the ambient air pressure, which led to the surrounding air, enhance air flow. This is a not only beautiful, but also very practical design. Because the following drive does not require too much air flow, so the noise is very low. Because the drive air driven ambient air, so the wind than usual "Micro Cooling Fan" is even higher. In addition, the general fan with blades cutting the air to promote air flow, so unpleasant. And this is a continuous flow of fan air flow, so more comfortable. Also, this "Micro Cooling Fan" not as a general fan as top-heavy, so more stable.
