14 Facts About Cooling fan
2.
The first rotary Cooling fan used in Europe was for mine ventilation during the 16th century, as illustrated by Georg Agricola .

4.
In 1998 William Fairbank and Walter K Boyd invented the high-volume low-speed ceiling fan, designed to reduce energy consumption by using long fan blades rotating at low speed to move a relatively large volume of air.

6.
Cross-flow or tangential Cooling fan, sometimes known as a tubular Cooling fan, was patented in 1893 by Paul Mortier, and is used extensively in heating, ventilation, and air conditioning, especially in ductless split air conditioners.

7.
The Cooling fan is usually long relative to its diameter, so the flow remains approximately two-dimensional away from the ends.

8.
The cross-flow Cooling fan uses an impeller with forward-curved blades, placed in a housing consisting of a rear wall and a vortex wall.
| FactSnippet No. 1,008,519 |
9.
One interesting phenomenon particular to the cross-flow Cooling fan is that, as the blades rotate, the local air incidence angle changes.

10.
Since the flow both enters and exits the impeller radially, the crossflow Cooling fan has been studied and prototyped for potential aircraft applications.
| FactSnippet No. 1,008,521 |
11.
In vehicles, a ducted Cooling fan is a method of propulsion in which a Cooling fan, propeller or rotor is surrounded by an aerodynamic duct or shroud which enhances its performance to create aerodynamic thrust or lift to transport the vehicle.

12.
In ventilation systems a jet Cooling fan, known as an impulse or induction Cooling fan, ejects a stream of air which entrains ambient air along with it, in order to circulate the ambient air.

13.
In machines with a rotating part, the Cooling fan is often connected to it rather than being powered separately.
| FactSnippet No. 1,008,524 |
14.
Large, slow-moving energy sources such as a flowing river can power a Cooling fan using a water wheel and a series of step-down gears or pulleys to increase the rotational speed to that which is required for efficient Cooling fan operation.
