Questions about the number of tubes in each tube side of the heat exchanger
Thread Content
Is it okay if the number of tubes on each tube side of the heat exchanger is different? Are there any specific requirements?
The same number of heat exchange tubes in each process is mainly to facilitate design and production. The number of heat exchange tubes in each process can be adjusted according to process needs.
There seems to be a requirement on 151 that the number of heat exchange tubes in each tube pass should be as equal as possible.
It has the same meaning as the circulation cross section mentioned on the second floor.

Can you change the splitting method?； Whether the user can accept the eccentric connection is really not acceptable. It is also said that the heat coefficient is calculated based on the average flow rate during calculation. . .
GB/T151-2014 6.3.2.2 For a multi-tube pass structure, the number of heat exchange tubes in each tube pass should be as similar as possible, the shape of the split-pass partition groove should be simple, and the length of the sealing surface should be short.
