Electric fan in Thailand Two box fans. Between 1882 and 1886 Schuyler Wheeler invented a fan powered by electricity. [9] It was commercially marketed by the American firm Crocker & Curtis electric motor company. In 1885 a desktop direct drive electric fan was commercially available by Stout, Meadowcraft & Co. in New York. [10]
The key components of a ceiling fan are the following: An electric motor; Blades (also known as paddles or wings) usually made from solid wood, plywood, steel, aluminium, MDF or plastic; Blade irons (also known as blade brackets, blade arms, blade holders, or flanges), which hold the blades and connect them to the motor.
A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, or squirrel-cage fan (because it looks like a hamster wheel).
Most of the Dyson fans and heaters are controlled by small infrared remote controls, which can be held magnetically on the appliance when not in use. A more-limited set of control switches is provided on the body of the appliance. The design for a "bladeless" fan had been patented by Toshiba in 1981, but was not marketed before the patent ...
A High-volume low-speed fan. A high-volume low-speed (HVLS) fan is a type of mechanical fan greater than 7 feet (2.1 m) in diameter. [1] HVLS fans are generally ceiling fans although some are pole mounted. HVLS fans move slowly and distribute large amounts of air at low rotational speed– hence the name "high volume, low speed."
A small blower fan is used to direct air across a laptop computer's CPU cooler. A case fan may be mounted on a radiator attached to the case, simultaneously operating to cool a liquid cooling device's working fluid and to ventilate the case. In laptops, a single blower fan often cools a heat sink connected to both CPU and GPU using heat pipes.
