n: see air-cooled exchanger. aerial river crossing n: a river crossing technique in which a pipeline is either suspended by cables over a waterway or attached to the girders of a bridge designed to carry vehicular traffic.

heat exchangers for cooling gas after compression.

n: an atmospheric fin tube exchanger that utilises air for cooling. Ambient air contacts the external fins by fanforced or natural draft. Also called air-fin unit or aerial cooler.

n: a heat exchanger that reduces the temperature of a fluid by transferring the heat to a nonprocess medium.

n: boiling, especially as applied to a system to remove heat from engine jacket water, wherein the water is permitted to boil and the evolved vapours are condensed in air-fin coolers.

n: on an engine, a device through which engine lubricating oil is circulated to reduce its temperature to acceptable levels. Some oil coolers depend on the surrounding air to reduce the temperature, but on most large engines, the oil is circulated through tubes that are surrounded by engine coolant.

n: a length of tubing or pipe bent to assume a coiled shape and through which a fluid cooler than the fluid outside the coil is circulated. The cooler fluid is used to cool the warmer fluid. Cooling causes vapors to condense to liquid.
