JLCPCB Solution: Air Multiplier

An air multiplier, sometimes called bladeless fan, is a fan which blows air from a ring with no external blades. Its vanes are hidden in its base and direct the collected airflow through a hollow tube or toroid, blowing a thin high-velocity smooth airflow from holes or a continuous slot across the surface of the tube or toroid. The first concept was created by Toshiba in 1981.-Wikipedia
