Marine heat exchangers play a crucial role in the maritime industry, functioning as the backbone of vessel engine cooling systems. These systems use the temperature differential between seawater and engine coolant to transfer heat. The jacket water cooling system, commonly associated with internal combustion engines, specifically aids in maintaining an optimal engine temperature, preventing overheating and promoting efficiency. Beyond engine cooling, marine heat exchangers also serve in other applications such as refrigeration, air conditioning, and heating systems onboard ships, thus ensuring a stable operation of the vessel's equipment.
