What is the role of the tube exchange in creating holes in the partition slots?
Thread Content
Are there some multi-pass tubular heat exchangers in which holes are intentionally made in the partitions? What is its function? See the figure. 4
The holes provided on the partition grooves can increase the heat transfer area of the tubular heat exchanger, thereby improving its heat transfer efficiency. The location and size of these holes are typically determined based on the design requirements of the heat exchanger and the process parameters. Furthermore, in multi-tube shell-and-tube heat exchangers, perforations can also facilitate fluid mixing between different tubes, thereby enhancing the heat exchange efficiency. At the same time, drilling also helps to reduce the impact of cross-flow convection, narrow the temperature difference, and prevent issues such as scaling and corrosion. .
I find it a bit weird; is it that I can’t understand the genius’s intention?
Guess: if there are studs at the corresponding positions on the split partition, then the holes in the partition slots are used for positioning； Otherwise, it may serve as a substitute for the tear holes in the dividing partition.
The second floor is answered by robots, which is absolutely ridiculous: lol
Mm-hmm, thank you. What you say makes sense; it might be a positioning function.
Positioning during the machining of tube sheet grooves may result in limited machining capacity
Later, I checked the partition plate in the tube box; there were no protrusions on the plate to fit with the grooves. It doesn’t seem to be for positioning.
