2. Evaporative cooler - Wikipedia

   en.wikipedia.org/wiki/Evaporative_cooler

   Evaporative cooling of ordinary helium forms a 1-K pot, which can cool to at least 1.2 K. Evaporative cooling of helium-3 can provide temperatures below 300 mK. These techniques can be used to make cryocoolers, or as components of lower-temperature cryostats such as dilution refrigerators. As the temperature decreases, the vapor pressure of the ...

3. Hopper cooling - Wikipedia

   en.wikipedia.org/wiki/Hopper_cooling

   Evaporative or steam cooling was used experimentally for high-powered aircraft engines in the 1930s, notably the Rolls-Royce Goshawk. [8] Although both systems rely on evaporation, they are quite different. Aircraft evaporative cooling, like radiator systems, used a pumped closed-loop for the coolant, without loss.

4. Turbine inlet air cooling - Wikipedia

   en.wikipedia.org/wiki/Turbine_Inlet_Air_Cooling

   An inlet air cooling system installed in a desert-dry area to increase turbine power output. Turbine inlet air cooling is a group of technologies and techniques consisting of cooling down the intake air of the gas turbine. The direct consequence of cooling the turbine inlet air is power output augmentation.

5. Air-cooled engine - Wikipedia

   en.wikipedia.org/wiki/Air-cooled_engine

   Most modern internal combustion engines are cooled by a closed circuit carrying liquid coolant through channels in the engine block and cylinder head. A fluid in these channels absorbs heat and then flows to a heat exchanger or radiator where the coolant releases heat into the air (or raw water, in the case of marine engines).

6. Intercooler - Wikipedia

   en.wikipedia.org/wiki/Intercooler

   Additional cooling can be provided by externally spraying a fine mist onto the intercooler surface, or even into the intake air itself, to further reduce intake charge temperature through evaporative cooling. Intercoolers can vary dramatically in size, shape and design, depending on the performance and space requirements of the system.

7. Fan (machine) - Wikipedia

   en.wikipedia.org/wiki/Fan_(machine)

   This is commonly seen in motor vehicles with internal combustion engines, large cooling systems, locomotives, and winnowing machines, where the fan is connected to the drive shaft or through a belt and pulleys. Another common configuration is a dual-shaft motor, where one end of the shaft drives a mechanism, while the other has a fan mounted on ...
