Marine engines convert thermal energy to mechanical energy that facilitates the propulsion of ships from one port to another. Internal combustion engines generate heat from burning fuel inside a cylinder to aid marine propulsion. Heat exchangers are used to keeping marine engine systems working.
Marine engine systems are interconnected by heat exchangers to cool or heat fluids. The type of heat exchanger used in marine engine systems depends on the applications’ requirements. Lube oil, jacket water, steam, and main seawater systems are some systems on board that use heat exchangers to prevent overheating.

Shell and tube type, plate type, plate-fin, dynamic scraped surface, phase change, spiral, and direct contact heat exchangers are some heat exchangers used onboard ships. Observe regular cleaning, checking of recommended temperature, and frequent inspections of heat exchangers to maximize their cooling effects on marine engine systems.
