Seeking help in selecting a heat exchanger
Thread Content
When using shell-and-tube heat exchangers, scaling can occur layer by layer, blocking the tubes and affecting heat transfer efficiency. I am looking for a better type of heat exchanger, preferably one with an automatic cleaning function. Thank you!
Use a bellows. Bellows can increase the heat transfer coefficient of the tube and shell sides. It enhances the heat transfer coefficient within the tube, and at the same time, the corrugated tube helps to delay scaling.

It’s all nonsense. With the scale buildup to that extent, what kind of heat exchanger can really solve the problem? Those who recommend other types of heat exchangers, such as corrugated tube or plate heat exchangers, dare they sign a contract? If problems still occur after use, will they be willing to compensate for the losses? Do they dare? I wouldn’t dare even borrow 10 of your guts! To address the root problem, multiple stages of water treatment—filtration and softening—should be carried out before the water enters the equipment; otherwise, continuous maintenance will be required!
What was said upstairs makes sense; I’d like to add that the filtering capability of plate heat exchangers is also very good
For soda heat exchange, you can consider spiral-wound heat exchangers; Shandong Miyou does a good job with these
It is recommended to use an automatic descaling and enhanced high-efficiency heat exchanger with segmented springs inside the tubes; for specific spring parameters and structural details, consult the relevant manufacturers.
For media with a strong tendency to form scale, changing the design of the heat exchanger has little effect; it is still necessary to focus on purifying the fluid
I agree with the opinion from the 6th floor: the surface of the heat exchange tubes varies in design, and some of these designs may delay the formation of scale, but they only provide temporary solutions rather than a permanent fix. Therefore, it’s still necessary to treat the water quality before it enters the heat exchanger.
