Several types of heat exchangers are commonly used in industrial settings, each with its own advantages and best use cases. Here are some of the most common types:
Shell and Tube Heat Exchangers: These are aptly named – the primary components are a tube pack and a shell to contain them. One fluid goes through the tubes, and the second goes through the larger shell surrounding the tubes. They can support higher operating temperatures and pressures than your typical plate heat exchanger. However, if the fluid in your application is very viscous or has particulates, it can foul up the tube and undermine the heat transfer process.
Plate Heat Exchangers: These are becoming preferred due to better heat transfer, easier maintenance and cleaning, modularity, and compactness. They are more efficient than shell and tube heat exchangers in many industrial and most HVAC applications.
Dimple Plate/Plate Coil Heat Exchangers: These offer the best of the above kinds of heat exchangers – they’re cheap, customizable, and compact but can withstand incredibly high pressures and temperatures due to design and materials.
The best type of heat exchanger for industrial use depends heavily on the particular process in which the heat exchanger is installed. Factors such as the type of fluids being used, the desired temperature change, the pressure, and the flow rate will all impact which type of heat exchanger is most suitable.
according to TEMA there are basically six types of heat exchangers (HEs). like wise TEMA type E, F,G etc. Type E is used for where no phase change is required..easy to construct...well suited for analysis and prediction purposes. for more details kindly refer the literature and books available.
