Problems with the inlet and outlet settings of the heat exchanger
Thread Content
Why are the inlet and outlet of the shell side of the heat exchanger in the figure on the same side? Could some expert please explain this?
One has flow from bottom to top and exit from top, while the other has flow from top to bottom and exit from bottom; it’s not hard to understand – it’s still counter-current heat exchange!
There is a partition in the central position, and the shell side is quite complex.
The shell type is Type F: a double-pass shell with a longitudinal partition, which divides the shell into two parts； The number of pipes is even, so the inlet and outlet are on the same side
In your diagram, there is a partition layer in the middle shell side; it’s not discharged directly
Double shell pass, with a partition plate in the middle, allowing the inlet and outlet to be on the same side.
The U-tube heat exchanger has a partition in the middle; it is the thick solid line shown in the diagram, which represents the partition
This is a U-tube heat exchanger with two flow paths, enabling full counter-current flow of the hot and cold fluids; partition plates in the shell side facilitate a U-shaped flow of the fluid in that section.
