A keel cooler is a type of internal combustion engine cooling system used in marine engines.. In this system, engine coolant is circulated through a system of tubing outside the vessel's hull, using the lower temperature of seawater to reduce the coolant temperature via heat exchange before it is recirculated through the engine.

This is most common when a ship is left pierside for an extended period of time. The steam system will be used to prevent condensation and rusting of vital engine room components. These heat exchangers are most often shell and tube heat exchangers due to the high temperature and pressures often utilized in steam systems.
In most familiar engines today, this water is circulated from the hot parts of the engine to a radiator, where it gives up its heat to the air. In early and low powered engines with hopper cooling there is little circulation. Water is instead slowly boiled off, with the heat of vaporisation needed to boil the water coming from the engine heat ...

A typical automotive cooling system comprises: a series of galleries cast into the engine block and cylinder head, surrounding the combustion chambers with circulating liquid to carry away heat; a radiator, consisting of many small tubes equipped with a honeycomb of fins to dissipate heat rapidly, that receives and cools hot liquid from the engine;
