Structural Characteristics Of Marine Plate Heat Exchanger

Plate heat exchangers for ships are mainly used in cruise ships, liquefied natural gas carriers, container ships and special ships for transporting cars. The main working conditions of the ship’s plate heat exchanger on the ship include the cooling of Structural characteristics of marine plate heat exchangerthe lubricating oil used by the ship’s main engine (called lubricating oil cooler); the cooling of the ship’s main generator, main engine and auxiliary machinery (called central cooling) Device) and desalination.

The structure of the plate heat exchanger for ships is the same as other heat exchanger equipment. The stainless steel, titanium and other corrosion-resistant metal flakes are flattened by a press and have design ripples. Synthetic rubber gaskets are used around them. The sheet is sealed to form a "heat transfer plate". The required number of the heat transfer plates are suspended on the guide rods, overlapped between the fixed frame made of steel plate and the movable frame, and fixed by screws. The high-temperature fluid medium and the low-temperature fluid medium alternately flow in the flow path formed between the plates to exchange heat. The main characteristics of the plate heat exchanger for ships are that the corrugated plate has high performance and high heat transfer efficiency; the volume is small, the overall structure is compact, and it does not occupy space. It can start quickly no matter when, and the environment is adaptable. It is easy to maintain and disassemble, it is very convenient to clean or replace the plate gasket.
