Shell and Tube Heat Exchanger is a heat exchange equipment widely used in chemical, petroleum, energy and other industries. According to its structure, it can be divided into the following four types.
Type | Fixed Tube Sheet Heat Exchanger | Floating Head Heat Exchanger | U-tube Heat Exchanger | Stuffing Box Heat Exchanger |
Features | The tube sheet and shell are fixed and the structure is relatively simple. | The tube sheet at one end is fixed, while the tube sheet at the other end can float freely, allowing the tube bundle to expand freely. | The tube bundle is bent into a U shape, with one end fixed and the other end free to expand. It has a compact structure and occupies a small area. | Use packing to seal and allow for some expansion. |
Suitable Temperature | Medium and low temperature | High temperature | Medium to high temperature | Medium temperature |
Suitable Working Conditions | Suitable for clean fluids and low maintenance applications. | High temperature difference | Larger temperature differences and thermal expansion | Medium temperature difference |
Maintenance Difficulty | High maintenance difficulty | Moderate maintenance difficulty | Medium to high maintenance | Low maintenance |
Difficulty of Cleaning | Difficult to clean, usually requires disassembly of the housing and a complex cleaning process. | The cleaning difficulty is medium. It can be cleaned relatively easily by pulling out the tube bundle, but the structure is complex. | The cleaning difficulty is medium to high, and the U-bend part is more difficult to clean. | The cleaning difficulty is relatively low, the tube bundle is easy to disassemble and assemble, and the cleaning process is relatively simple. |
Cost | Low manufacturing cost and simple structure | Manufacturing costs are moderate to high, with complex design and floating head components adding to the cost. | The manufacturing cost is moderate, and the manufacturing complexity of the U-tube and elbow parts increases the cost. | The manufacturing cost is medium to high, and the manufacturing requirements for stuffing boxes and seals are high. |
Applicable Media | Suitable for relatively clean fluids without large amounts of solid particles or sticky substances. | Solid or viscous media can be processed because the floating head design allows the tube bundle to be pulled out for easy cleaning. | Suitable for fluids with large thermal expansion, because the U-tube design allows the tube bundle to expand freely. | Suitable for media that require frequent maintenance and cleaning. |
In addition to the above factors, when purchasing a heat exchanger, you also need to choose the right material and design based on the corrosiveness of the medium or whether it contains sediment, the service life and durability of the heat exchanger, installation and space requirements, and choose appropriate leakage protection measures based on the medium characteristics and operating conditions, etc.
By comprehensively considering these factors, you can choose the heat exchanger that best suits your application needs and ensure its performance and economy in actual use.
