Types of Plate Type Heat Exchanger

1. 5 Commonly Used Types of Hear Exchangers on Ship!! Ships use heat exchangers in different ways on a ship. It depends on the application and requirement of the heat exchanger for a particular usage. A ship's systems are almost entirely dependent on plate type heat exchanger, which heat or cool the fluid. They classify exchangers primarily based on their construction, and they are as follows: 1) Shell and Tube Type Heat Exchanger Most popular, this design has a shell accompanied by several tubes, with the primary liquid mainly flowing through the pipes, while the second fluid

A heat transfer process occurs between two fluids that are placed on opposite sides of the plate. Heat exchangers of this type are more expensive to install than those of the shell and tube type, but they cost less to maintain. With the same size of the unit, plate-type pumps are more efficient than shell and tube types. They can also withstand high pressures. 3) Plate Fin Heat Exchanger It construct similarly plating and fin heat exchangers to plate-type exchangers but with fins to improve efficiency. They improve heat transfer with aluminum alloy, which is lighter and lower in weight. 4) Dynamic Scraped Surface Heat Exchanger This heat exchanger can operate for a longer period of time because of the continuous scraping of the surface, which helps improve the efficiency of heat transfer and reduce fouling. With a motor-driven shaft and a timer inside the frame, the blade unit scrapes with a motor. They commonly use heat exchangers like this for transferring heat from highly viscous fluids by increasing the fluid's turbulence. Due to the auto cleaning process, maintenance is less expensive than other types. 5) Phase Change Heat Exchanger Heat exchangers of this type are designed to convert a solid into a liquid or a liquid to gas using the principle of heat transfer. It is normal for this type to operate in freeze and melt cycles for phases to change. They usually built heat exchangers as shell-and-tube exchangers, but usually consist of at least two divider walls that create upper and lower annular spaces for flow passage. In addition, they equip both passageways with fins to facilitate efficient heat transfer. Conclusion Ships also make use of used Alfa Laval Heat Exchanger for better functioning. But, the problem is where to find used parts of good quality and
