How to add guide cylinders to a heat exchanger
Thread Content
When is it necessary to add guide cylinders to the heat exchanger? I searched around in HTRI for a long time but couldn’t find where to add guide cylinders. Can HTRI be used to add guide cylinders to heat exchangers? Thank you
What I know is that guide cylinders are installed at the inlet and outlet of heat exchangers to make the fluid distribution at the inlet more uniform; these are usually external guide cylinders, and they are employed in heat exchangers with a relatively large shell diameter. For more detailed information on this topic, I think the original poster should consult additional materials – it seems that HTFS can be used for such designs
It can be divided into several aspects: there is an inner flow guide cylinder and an outer flow guide cylinder. The inner flow guide cylinder is primarily used to reduce dead zones, improve heat transfer efficiency, and prevent erosion of the heat exchange tubes. The outer flow guide cylinder serves mainly to increase the number of tubes and ensure even fluid distribution. It is designed specifically for certain issues, but generally the pressure isn’t too high
After looking at it for a long time, I still don’t quite understand how to add external guide cylinders to a heat exchanger when using HTRI for its design. Is it impossible to add such cylinders at all, or is it only necessary to specify this requirement when giving instructions to the heat exchanger manufacturer?
