An engine cooled directly by a stream of air without the interposition of a liquid medium.

air-cooled engine

A reciprocating engine that depends on cooling by the air mass rather than on liquid coolants. The cooling is directed by radiating heat to the air flowing between the fins around the cylinder head or around a hot rotor casing in the case of a rotating combustion engine.

This placement resulted in an extremely high air velocity under these racks, meaning that the volumetric airflow rate issuing from the dedicated tiles was less than optimal (see airflow discussion in the "Comparison of Air-Cooled and Liquid-Cooled Servers" section).
The plant manufactures helical rotor and scroll water- and air-cooled chillers, compressors and cold generators.
There is also minimal noise and no need for air-conveyance ducts to remove hot air generated by air-cooled chillers.
Hudson is a global heat transfer solutions firm that provides custom-designed, highly engineered air-cooled heat exchangers and axial-flow fans, and also offers aftermarket parts and services.
Air-cooled system with ambient-temperature, closed-circuit, air/water ventilated heat exchanger eliminates a cooling tower.
Thermal Care is just now bringing to market models of these chillers designed to work with an outdoor, air-cooled remote condenser to supplement the initial water-cooled versions designed to work with cooling towers.
Performance for the new air-cooled frame models has been increased up to 60 percent over the equivalent current models.
Hudson and its affiliated companies have nearly 70 years of experience in producing high quality axial-flow fans and air-cooled heat exchangers.
Cooling equipment includes central systems with semi-hermetic open drive or screw compressor; air-cooled units with heat recovery; water-cooled units with "free cooling"; clean-water tower systems; prepackaged mezzanine systems; portable chillers; blown-film coolers; temperature-control units; chemical-treatment packages; mold-area dehumidifiers; and water-filtration systems.
The Model 180 provides a new lower-cost entry point to the ES/9000 air-cooled frame processors, while the Model 200 delivers an increased level of processing power to the ES/9000 rack-mounted processors.
We now run a fully operational manufacturing plant that is producing plates for our 400kW air-cooled PAFC fuel cell module, which serves as the building block of HydroGen's core product, a 2MW Power Island.
It is also the first supercomputer to be fully implemented with gallium arsenide (GaAs) semiconductor technology, which increases the speed of the system while maintaining a low-maintenance, air-cooled package.
