Heat Exchangers : Header Tank Heat Exchanger

A heat exchanger is any type of device used to transfer heat from between mediums. A header tank is a tank or reservoir that is mounted at the top of a device to maintain static pressure on a fluid. A header tank heat exchanger is one in which the header tank is mounted above the engine and the engine water is circulated through the tube stack to dissipate heat. Header type heat exchangers are very common on marine engines, but are also used in other applications such as generator sets and fire pumps.
