Application of plate heat exchanger in marine turbine
In marine turbines, heat exchange is undoubtedly a very important factor in ensuring the normal use of the turbine. When the turbine is working, it needs to maintain a certain temperature to ensure the normal operation of the machine. At present, there are already very well-designed heat exchangers in the marine turbine. Among them, the plate heat exchanger is one of the most important ones, and it is a machine with great development potential in the future.
The principle of the plate heat exchanger is actually very simple, basically consisting of many channel plates and a blind plate and end plates. The latter is located at both ends of the heat exchanger, so it is very helpful for the transfer and the sealing of the passage. In this system, the hot air is basically flowed from one direction to another. The channel board is the place where the medium exists. When the air is present, these mediums are basically the heat dissipating medium. When the hot air is in contact with these mediums, the purpose of heat dissipation is achieved. There is a very wide range of uses in the industry, not just in the marine industry.
Plate heat exchangers have become one of the most important equipment in ships. For example, heat exchangers are used in equipment such as main and auxiliary oil coolers, cylinder liner fresh water coolers, fuel heaters, steam condensers and feed water heaters. However, the special working environment of the ship is very demanding on the heat exchanger. The special environment includes factors such as instability on the sea surface, and may encounter vibration, shock, large angle tilt and noise. The cooling medium is generally sea water, including the salt concentration is large, the working environment is high in humidity, and the corrosion of the plate is very strong. The space of the ship itself is very compact, and the space and quality occupied by the heat exchanger are more severely restricted. The conventional heat exchanger is often water and water. the heat transfer medium for ship plate heat exchangers is generally oil and water,.The emergence of plate heat exchangers has effectively solved a large part of the problem.
