A engine heat sink is a heat exchanger used to cool an internal combustion engine, mainly in automobiles, but also in aircraft with piston engines, railway locomotives, motorcycles, stationary power plants, or any similar use of such engines. In automotive and motorcycles with liquid-cooled internal combustion engines, the heat sink is connected to passages running through the engine and cylinder heads through which liquid (coolant) is pumped. This fluid may be water (in climates where water is less likely to freeze), but more often it is a mixture of water and antifreeze in proportions appropriate for the climate. The antifreeze itself is usually ethylene glycol or propylene glycol (with a small amount of corrosion inhibitor).
A typical automotive cooling system includes:
A series of channels cast into the engine block and cylinder head that circulate fluid around the combustion chamber to remove heat.
A heat sink, consisting of many small tubes with honeycomb-shaped fins to dissipate heat quickly, to receive and cool hot fluid from the engine.
A water pump, usually centrifugal, to circulate the coolant through the system.
The thermostat controls the temperature by changing the amount of coolant entering the heat sink.
A fan that draws cool air through the heat sink.
