Plate Heat Exchanger Apply in Marine

Plate-type marine heat exchangers are designed with sets of multiple parallel plates that are compressed to form the main cooler unit. This type has a small footprint in comparison to other types of heat exchangers. The plates are designed in such a way that when placed next to each other they create passageways to the fluid to flow between the plates. Gaskets are placed around the edge of each plate in order to prevent the mixing of the two fluids. Due to the temperature and pressure constraints of the rubber used to make the gaskets plate type heat exchangers are used for low pressure, low temperature applications, under 290 psig (20 bar) and 300 degrees Fahrenheit (150 degrees Celsius)

Heat generated due to friction is carried away from an engine in the lube oil. Lube oil pass through a heat exchanger where the heat is passed to a central engine room cooling loop before the heat is rejected to the ocean.

Unlike most systems with heat exchangers, steam is used to heat other systems. 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.

Regular maintenance of heat exchangers is important in order to maintain the heat exchanger's maximum efficiency. Sacrificial anodes are necessary in cooling systems to prevent galvanic corrosion. Anodes are often time made of Zinc and are replaced when they reach fifty percent wear. Shell and tube heat exchangers require tubes to be plugged upon the detection of a leak. This prevents the two liquids from mixing inside the heat exchangers. In order to perform regular maintenance on a plate type heat exchanger, the plate stack is separated and the plates a cleaned to improve heat transfer.
