Heat exchangers: air-cooled, finned, shell-and-tube, spiral-wound tube, detachable plate type
Thread Content
I have been working in the field of heat exchangers for many years, and I hope to exchange ideas with everyone regarding various issues related to heat exchangers. Feel free to ask questions
Are you working on heat transfer, structure, or systems?
Heat transfer calculations; the school system is currently under consideration
There is not much evaporation; more condensation, cooling, and heating takes place
1. How to calculate the optimal water level in a phase change furnace； 2. Causes of leakage in floating-head heat exchangers
May I ask whether a spiral-wound tubular heat exchanger can be used as a top condenser in a distillation column? If not, why? For the same heat transfer medium, is the heat transfer coefficient of coiled tubes much higher than that of shell-and-tube exchangers?
Indeed, under the same conditions, the heat transfer coefficient of coiled tubes is higher than that of shell-and-tube exchangers; this applies specifically to condensation processes, where the heat transfer coefficient is very high, but it is not that high for cooling purposes
I haven’t worked with phase change furnaces, but I can answer the second question. Leaks in floating-head heat exchangers are quite common; as the name suggests, the rear part of such exchangers is floating, and that’s why companies usually don’t construct the rear floating parts very well, which results in poor sealing. These days, a double-sealing structure is often used for the rear part
I have been working on the design of plate-fin heat exchangers for over a decade; I am not very familiar with other types of heat exchangers. If there is a need, I wonder if I can provide some assistance? I hope we can communicate more
