Background
The oil cooler is an important heat exchange device commonly used in the field of ships, and mainly used for cooling the working heated oil to keep the oil at a proper temperature. When the temperature of the lubricating oil is too high or too low, accidents of the diesel engine can be caused.
In order to meet various restriction factors of ships, a floating head heat exchanger is generally adopted in the current oil cooler for ships. The floating head heat exchanger is one kind of tubular heat exchanger, and consists of mainly casing, pipe plate, end caps, pipe bundle, etc. and is one kind of dividing wall type heat exchanger with the wall of the pipe bundle as heat transferring surface. The heat exchanger can work in high-temperature and high-pressure occasions, the tube bundle can be drawn out of the shell, and the cleaning is convenient, but the heat exchanger has the advantages of large metal consumption, large volume and high cost.
The plate heat exchanger is heat exchange equipment which takes convection heat transfer and heat conduction as main means. The heat exchanger has the advantages of high heat exchange efficiency, compact and light structure, small occupied area, long service life and low production cost. Under the condition of the same pressure loss, the heat transfer efficiency of the heat exchanger is more than 2 times that of the tube heat exchanger, and the floor area of the heat exchanger is only one third of that of the tube heat exchanger. However, the allowable stress of the plate heat exchanger in China is generally lower than that of a tubular heat exchanger at present, and the plate heat exchanger is limited by temperature and pressure and cannot be widely used in the field of ships.
In order to utilize energy more efficiently and save limited space, it is of great significance to develop a lubricant cooler with higher heat exchange efficiency and smaller volume under the condition of meeting various restriction factors of ships.
