Fans are used to force air into low- and high-bypass jet engines, seen here on a Boeing 777. A fan is a powered machine used to create a flow of air. A fan consists of a rotating arrangement of vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an impeller, rotor ...
Air-cooled engine. Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them in order to keep the engine within operating temperatures. Air-cooled designs are far simpler than their liquid-cooled counterparts, which require a separate radiator, coolant reservoir, piping and pumps.
Computer cooling. A finned air cooled heatsink with fan clipped onto a CPU, with a smaller passive heatsink without fan in the background. A 3-fan heatsink mounted on a video card to maximize cooling efficiency of the GPU and surrounding components. Commodore 128DCR computer's switch-mode power supply, with a user-installed 60 mm cooling fan.
I've been hands-on with the JBL Live Beam 3 earbuds. These clever noise-cancelling buds come with a screen on the case, along with loads of extra features. Why I'm a fan of the new JBL Live Beam 3 ...
Here’s everything you need to know to attend the concert: Date: Friday, August 30. Check-in: By 5:15am (concert concludes at 9:30 a.m.) Where: 48th Street and Rockefeller Plaza (between 5th and ...
Passive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building in order to improve the indoor thermal comfort with low or no energy consumption. [ 1][ 2] This approach works either by preventing heat from entering the interior (heat gain prevention) or by removing heat from the building ...
If you're looking for great buds that aren't fruit-themed, consider the Sony WF-1000XM4 noise-canceling earbuds, currently on sale at Amazon for $198 (from $279). There are also a lot of other ...
Radiative cooling. Earth's longwave thermal radiation intensity, from clouds, atmosphere and surface. In the study of heat transfer, radiative cooling [1] [2] is the process by which a body loses heat by thermal radiation. As Planck's law describes, every physical body spontaneously and continuously emits electromagnetic radiation .
