Plate heat exchangers for ships are mainly used in cruise ships, LNG carriers, container ships and special ships for transporting cars. Some also apply to luxury tourist cruise ships. It can be said that the application is quite extensive.

The main working conditions of marine plate heat exchangers on ships include the cooling of the lubricating oil used by the ship's main engine, which is called the lubricating oil cooler; there is also the cooling of the main generator on the ship, the main engine and the auxiliary machinery, which is called the central Coolers; seawater desalination; widely used in these conditions.

The plate heat exchanger for ships has the same structure as other heat exchanger equipment. On the sheet of corrosion-resistant metal such as stainless steel and titanium, it is flattened by a press with a design ripple, and synthetic rubber is used around it The gasket is sealed, forming a "heat transfer plate". A required number of the above-mentioned heat transfer plates are suspended from a guide rod, overlapped between a steel frame fixed frame and a moving frame, and fixed with a screw. The high-temperature fluid medium and the low-temperature fluid medium are separated from each other by a flow path formed between the plates for heat exchange.

The characteristics of plate heat exchangers for ships are very obvious, mainly the corrugated plate has high performance and high heat transfer efficiency; small size, compact overall structure, does not take up space; fast start at any time, strong environmental adaptability ; Easy to maintain and disassemble, whether it is cleaning or replacing plate gaskets.
