Ocean shipping is the most important mode of transportation in international logistics, a service industry that uses ships to transport goods or passengers between ports in different countries and regions via sea routes. Compared with air and land transport, ocean shipping has advantages such as large capacity, high flexibility, and lower cost, making it particularly suitable for transporting large quantities of goods over long distances, but it requires a longer time. The marine industry also faces significant challenges; the implementation of the Energy Efficiency Index (EEXI) and Carbon Intensity Index (CII) has forced shipping companies to take measures to improve energy efficiency or reduce sailing speed. Plate heat exchangers (PHEs), with their high efficiency, compactness, and flexibility, have become one of the key pieces of equipment for the shipping industry to achieve energy conservation, environmental protection, and improved operational reliability.
Plate heat exchangers allow two media at different temperatures to exchange heat without mixing through a single PHE Plate. Corrugated Heat Exchanger Plates are assembled between a frame and pressure plates, with gaskets placed in the grooves of the plates for sealing. The counter-current flow of the fluids is smooth, and the thin plates and corrugated structure create highly turbulent, high-heat-transfer-efficiency fluid channels, enabling the most efficient heat exchange between the two fluids within a minimal volume.
On ships, plate heat exchangers are core components of various cooling and heating systems, ensuring the normal operation of shipboard machinery and environmental systems.
Plate heat exchangers act as central coolers (Fresh Water Generator/ Central Cooler), using seawater to cool the ship's circulating freshwater.
Cooling the cylinder liner water of the main propulsion diesel engine and generator; Cooling the lubricating oil and HFO of the main and auxiliary engines; Cooling hydraulic oil.
Plate heat exchangers utilize waste heat steam or hot water to heat fuel oil; Evaporate seawater to produce the required freshwater; Recover heat energy from exhaust gases, improving the ship's energy efficiency.
Traditional shipboard cooling systems typically use seawater to directly cool all equipment. However, seawater's high salinity, corrosiveness, and susceptibility to marine organisms lead to scaling and blockages in pipes and heat exchangers. Using plate heat exchangers separates high-temperature freshwater from low-temperature seawater, efficiently transferring heat from the freshwater side to the seawater side. The addition of rust and scale inhibitors protects the cooling systems and piping of critical equipment. The cooled freshwater is returned to the ship's equipment for further cooling, while the heated seawater is discharged overboard. The removable structure of plate heat exchangers allows for simple and quick maintenance, reducing downtime.
