　　无叶风扇也叫空气增倍机，其造型奇特，外表既流线又清爽。如今，第三代无叶风扇已经在市场上普及，其外形更时尚、有创意。不过Ameya360还是很好奇没有了传统风扇的“叶”，它是怎么带来凉风的呢？

无叶风扇的介绍 无叶风扇的工作原理

　　原来，无叶风扇基座中带有的40瓦电力马达每秒钟将33升的空气吸入风扇基座内部，经由气旋加速器加速后，空气流通速度最大被增大16倍左右，经由无叶风扇扇头环形内唇环绕，其环绕力带动扇头附近的空气随之进入扇头，并以高速度向外吹出。

　　无叶风扇利用喷气式飞机引擎及汽车涡轮增压中的技术，通过底部的吸风孔吸入空气，圆环边缘的内部隐藏的一个叶轮则把空气以圆形轨迹喷出，最终形成一股不间断的冷空气流。重要的是这种空气流动比普通风扇产生的风更平稳。它产生的空气量相当于目前市场上性能最好的风扇。

　　很多无叶风扇同时带有变频风速大小调节装置，方便用户根据实际情况调节风速的大小，风量均匀增加，不会冲击电压，能耗低，是普通风扇一半能耗。同时气流也会通过粘滞力带动圆环中的空气向前运动。两种效应叠加的结果理论上可以使实际吹出的空气量为流过基座空气量的整整15倍！
