[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and transport gas. It is a driven fluid machine. Commonly referred to fans include ventilators, blowers, wind turbines, gas compression and gas delivery machines, which convert rotational mechanical energy into gas pressure energy and kinetic energy and transport the gas. The main structural components of a fan are impeller, casing, air inlet, bracket, motor, pulley, coupling, muffler, transmission parts (bearings), etc. An unpowered ventilator uses natural wind and the air heat convection caused by the temperature difference between indoor and outdoor to drive the turbine to rotate, thereby using centrifugal force and negative pressure effect to discharge stale hot air from the room.
