2. Infrared heater - Wikipedia

   en.wikipedia.org/wiki/Infrared_heater

   There may be a wire guard over the front of the shroud, to prevent touching the hot surface of the bulb. Ordinary household white incandescent bulbs can also be used as heat lamps , but red and blue bulbs are sold for use in brood lamps and reptile lamps. 250 watt heat lamps are commonly packaged in the "R40" (5" reflector lamp) form factor ...

3. Radiator (engine cooling) - Wikipedia

   en.wikipedia.org/wiki/Radiator_(engine_cooling)

   a thermostat to control temperature by varying the amount of coolant going to the radiator; a fan to draw cool air through the radiator. The combustion process produces a large amount of heat. If heat were allowed to increase unchecked, detonation would occur, and components outside the engine would fail due to excessive temperature. To combat ...

4. Computer fan - Wikipedia

   en.wikipedia.org/wiki/Computer_fan

   Fans are, less commonly, used for other purposes such as: Water-cooling radiator transfers a lot of heat, and radiator fans have large static pressure (opposed to case fans that have high airflow) for dissipating heat. Laptop computers lack large openings in the case for warm air to escape.

5. Air-cooled engine - Wikipedia

   en.wikipedia.org/wiki/Air-cooled_engine

   With the much smaller radiators and less fluid in the system, the weight and drag of these designs was well below contemporary air-cooled designs. On a weight basis, these liquid-cooled designs offered as much as 30% better performance. [6] In the late- and post-war era, the high-performance field quickly moved to jet engines. This took away ...

6. Ducted fan - Wikipedia

   en.wikipedia.org/wiki/Ducted_fan

   In aeronautics, a ducted fan is a thrust-generating mechanical fan or propeller mounted within a cylindrical duct or shroud. Other terms include ducted propeller or shrouded propeller . [ 1 ] When used in vertical takeoff and landing ( VTOL ) applications it is also known as a shrouded rotor .

7. Aircraft engine - Wikipedia

   Counter-clockwise from top left: propeller hub, mast with belt guide, radiator, Wankel engine, muffler shroud. The Wankel is a type of rotary engine. The Wankel engine is about one half the weight and size of a traditional four-stroke cycle piston engine of equal power output, and much lower in complexity. In an aircraft application, the power ...
