4 Terms and definitions
4.1 Cooling systems
4.1.1
liquid cooling
cooling system in which a liquid coolant is used as the transfer fluid
4.1.2
evaporative cooling
liquid cooling system in which engine heat is dissipated by evaporating liquid coolant
4.1.3
single evaporative cooling
evaporative cooling where evaporative losses in the liquid coolant are compensated by refilling
See Figure 2.
4.1.4
evaporative cooling with additional tank
evaporative cooling where the liquid coolant is supplemented by an additional tank
See Figure 3.
4.1.5
evaporative cooling with cond enser
evaporative cooling where the evaporated transfer liquid settles in a condenser and flows back to the cooling circuit top-up coolant tank of the engine
See Figure 4.
4.1.6
circulative cooling
cooling by circulating liquid coolant which is recooled
4.1.7
convective cooling
cooling by a liquid coolant in which natural circulation is achieved by the thermal siphon
phenomenon
See Figure 5.
4.1.8
force-feed
cooling by a liquids crculatio is achieved cglon in which freree byapump
4.1.15
oil cooling
cooling system in which oil is the transfer medium
4.1.16
oil-cooled engine
engine in which the engine lubricating oil is used as the cooling medium instead of a water-based coolant
See Figure 9.
4.1.1 7
oil/air-cooled engine
engine in which either the cylinder head is cooled by air with the cylinder liner cooled and the engine frictional heat removed by the engine lubricating oil, or the cylinder liner is cooled by air with the cylinder head cooled and the engine frictional heat removed by the engine lubricating oil
See Figure 10.
NOTE The heat in the engine lubricating oil is removed in the engine lubricating oil cooler.
4.2.2
header tank
tank containing a certain amount of reserve liquid, located above the heat exchange and, in some
cases, combined with it
4.2.3
interior evaporation unit
4.2.6
liquid-to-liquid heat exchanger
primary (inner) to secondary (outer) liquid coolant heat exchanger
4.2.7
fresh water cooler
liquid-to-liquid heat exchanger in which the engine liquid coolant (primary) circuit is cooled by a secondary coolant (e.g. seawater)
4.2.8
keel cooler
liquid-to-liquid heat exchanger fitted on ships, either as a flat coolant tank attached to the inner surface of the hull or, outside, to the keel as a tubular system
4.2.9
oil cooler
heat exchanger for lubricating oil
4.2.10
liquid-cooled oil cooler
cooler that transfers heat from the lubricating oil to the liquid coolant
See Figure 14.
4.2.16
fan
component which generates a forced air stream for air cooling
4.2.17
liquid coolant pump
pump which circulates the liquid coolant through a force-feed cooling system
4.2.18
thermostat
component for controlling the liquid coolant flow dependant upon temperature
NOTE The thermostat allows part of the flow to by-pass the cooler.
4.2.19
cooling airduct
airduct used to convey the cooling airflow to or from the engine parts to be cooled
See Figure 19.
