about
Shell & Tube Heat Exchangers
A shell and tube heat exchanger is one of the most reliable and universal thermal management solutions used in innumerable industries. As professional shell and tube heat exchanger manufacturers, we've witnessed directly how these systems provide reliable performance even in challenging operating conditions. Here's why these systems work so well:
- Fluid Flow: In the conventional shell and tube heat exchanger configuration, one fluid is pumped inside the inner tubes and a second fluid flows outside them within the outer casing.
- Heat Transfer: What's so appealing about this design is the manner in which thermal exchange is managed. Whether operating with counterflow (oppositely directed flows of fluids) or parallel flow, the tube heat exchanger makes it easy for heat transfer to occur from the hotter fluid to the cold fluid via the conductive walls of the tube.
- Cooling/Heating: As it operates, the warmer fluid slowly cools as it dissipates thermal energy, while the colder fluid heats up as it takes in this heat.
Types of
Shell & Tube Heat Exchangers
Fixed Tube Sheet
- The simplest of shell and tube heat exchanger designs employs tubes that are rigidly fixed to tube sheets, these being attached to the outer shell. This simple method provides excellent reliability but does complicate internal tube cleaning.
Removable Tube Bundle
- When maintenance access is a priority, this design from seasoned shell and tube heat exchanger manufacturer makes it possible for the entire tube assembly to be pulled out of the shell for complete cleaning and inspection. The tubes remain attached to their tube sheets but can be quickly taken out of the main housing when required.
U-Tube
- This innovative tube heat exchanger design has U-bent tubes whose both ends are attached to a common tube sheet. Since this design accommodates natural expansion and contraction of the tubes, this configuration is ideal for applications where there is a lot of thermal cycling.
Coil in Tank
- For some applications, this specialized design puts coiled tubing right inside a tank vessel. One fluid passes through these coils while the second fluid envelops them in the tank, providing effective heat transfer in a small space.
Double Pipe
- Bashfulness is sometimes the best policy. This basic shell and tube heat exchanger consists of two pipes nested within each other. One fluid flows inside the inner pipe and the other inside the gap between pipes, providing simple but efficient thermal transfer for particular applications.
